- Linux kernel management style
-
-This is a short document describing the preferred (or made up, depending
-on who you ask) management style for the linux kernel. It's meant to
-mirror the CodingStyle document to some degree, and mainly written to
-avoid answering (*) the same (or similar) questions over and over again.
-
-Management style is very personal and much harder to quantify than
-simple coding style rules, so this document may or may not have anything
-to do with reality. It started as a lark, but that doesn't mean that it
-might not actually be true. You'll have to decide for yourself.
-
-Btw, when talking about "kernel manager", it's all about the technical
-lead persons, not the people who do traditional management inside
-companies. If you sign purchase orders or you have any clue about the
-budget of your group, you're almost certainly not a kernel manager.
-These suggestions may or may not apply to you.
-
-First off, I'd suggest buying "Seven Habits of Highly Successful
-People", and NOT read it. Burn it, it's a great symbolic gesture.
-
-(*) This document does so not so much by answering the question, but by
-making it painfully obvious to the questioner that we don't have a clue
-to what the answer is.
-
-Anyway, here goes:
-
-
- Chapter 1: Decisions
-
-Everybody thinks managers make decisions, and that decision-making is
-important. The bigger and more painful the decision, the bigger the
-manager must be to make it. That's very deep and obvious, but it's not
-actually true.
-
-The name of the game is to _avoid_ having to make a decision. In
-particular, if somebody tells you "choose (a) or (b), we really need you
-to decide on this", you're in trouble as a manager. The people you
-manage had better know the details better than you, so if they come to
-you for a technical decision, you're screwed. You're clearly not
-competent to make that decision for them.
-
-(Corollary:if the people you manage don't know the details better than
-you, you're also screwed, although for a totally different reason.
-Namely that you are in the wrong job, and that _they_ should be managing
-your brilliance instead).
-
-So the name of the game is to _avoid_ decisions, at least the big and
-painful ones. Making small and non-consequential decisions is fine, and
-makes you look like you know what you're doing, so what a kernel manager
-needs to do is to turn the big and painful ones into small things where
-nobody really cares.
-
-It helps to realize that the key difference between a big decision and a
-small one is whether you can fix your decision afterwards. Any decision
-can be made small by just always making sure that if you were wrong (and
-you _will_ be wrong), you can always undo the damage later by
-backtracking. Suddenly, you get to be doubly managerial for making
-_two_ inconsequential decisions - the wrong one _and_ the right one.
-
-And people will even see that as true leadership (*cough* bullshit
-*cough*).
-
-Thus the key to avoiding big decisions becomes to just avoiding to do
-things that can't be undone. Don't get ushered into a corner from which
-you cannot escape. A cornered rat may be dangerous - a cornered manager
-is just pitiful.
-
-It turns out that since nobody would be stupid enough to ever really let
-a kernel manager have huge fiscal responsibility _anyway_, it's usually
-fairly easy to backtrack. Since you're not going to be able to waste
-huge amounts of money that you might not be able to repay, the only
-thing you can backtrack on is a technical decision, and there
-back-tracking is very easy: just tell everybody that you were an
-incompetent nincompoop, say you're sorry, and undo all the worthless
-work you had people work on for the last year. Suddenly the decision
-you made a year ago wasn't a big decision after all, since it could be
-easily undone.
-
-It turns out that some people have trouble with this approach, for two
-reasons:
- - admitting you were an idiot is harder than it looks. We all like to
- maintain appearances, and coming out in public to say that you were
- wrong is sometimes very hard indeed.
- - having somebody tell you that what you worked on for the last year
- wasn't worthwhile after all can be hard on the poor lowly engineers
- too, and while the actual _work_ was easy enough to undo by just
- deleting it, you may have irrevocably lost the trust of that
- engineer. And remember: "irrevocable" was what we tried to avoid in
- the first place, and your decision ended up being a big one after
- all.
-
-Happily, both of these reasons can be mitigated effectively by just
-admitting up-front that you don't have a friggin' clue, and telling
-people ahead of the fact that your decision is purely preliminary, and
-might be the wrong thing. You should always reserve the right to change
-your mind, and make people very _aware_ of that. And it's much easier
-to admit that you are stupid when you haven't _yet_ done the really
-stupid thing.
-
-Then, when it really does turn out to be stupid, people just roll their
-eyes and say "Oops, he did it again".
-
-This preemptive admission of incompetence might also make the people who
-actually do the work also think twice about whether it's worth doing or
-not. After all, if _they_ aren't certain whether it's a good idea, you
-sure as hell shouldn't encourage them by promising them that what they
-work on will be included. Make them at least think twice before they
-embark on a big endeavor.
-
-Remember: they'd better know more about the details than you do, and
-they usually already think they have the answer to everything. The best
-thing you can do as a manager is not to instill confidence, but rather a
-healthy dose of critical thinking on what they do.
-
-Btw, another way to avoid a decision is to plaintively just whine "can't
-we just do both?" and look pitiful. Trust me, it works. If it's not
-clear which approach is better, they'll eventually figure it out. The
-answer may end up being that both teams get so frustrated by the
-situation that they just give up.
-
-That may sound like a failure, but it's usually a sign that there was
-something wrong with both projects, and the reason the people involved
-couldn't decide was that they were both wrong. You end up coming up
-smelling like roses, and you avoided yet another decision that you could
-have screwed up on.
-
-
- Chapter 2: People
-
-Most people are idiots, and being a manager means you'll have to deal
-with it, and perhaps more importantly, that _they_ have to deal with
-_you_.
-
-It turns out that while it's easy to undo technical mistakes, it's not
-as easy to undo personality disorders. You just have to live with
-theirs - and yours.
-
-However, in order to prepare yourself as a kernel manager, it's best to
-remember not to burn any bridges, bomb any innocent villagers, or
-alienate too many kernel developers. It turns out that alienating people
-is fairly easy, and un-alienating them is hard. Thus "alienating"
-immediately falls under the heading of "not reversible", and becomes a
-no-no according to Chapter 1.
-
-There's just a few simple rules here:
- (1) don't call people d*ckheads (at least not in public)
- (2) learn how to apologize when you forgot rule (1)
-
-The problem with #1 is that it's very easy to do, since you can say
-"you're a d*ckhead" in millions of different ways (*), sometimes without
-even realizing it, and almost always with a white-hot conviction that
-you are right.
-
-And the more convinced you are that you are right (and let's face it,
-you can call just about _anybody_ a d*ckhead, and you often _will_ be
-right), the harder it ends up being to apologize afterwards.
-
-To solve this problem, you really only have two options:
- - get really good at apologies
- - spread the "love" out so evenly that nobody really ends up feeling
- like they get unfairly targeted. Make it inventive enough, and they
- might even be amused.
-
-The option of being unfailingly polite really doesn't exist. Nobody will
-trust somebody who is so clearly hiding his true character.
-
-(*) Paul Simon sang "Fifty Ways to Lose Your Lover", because quite
-frankly, "A Million Ways to Tell a Developer He Is a D*ckhead" doesn't
-scan nearly as well. But I'm sure he thought about it.
-
-
- Chapter 3: People II - the Good Kind
-
-While it turns out that most people are idiots, the corollary to that is
-sadly that you are one too, and that while we can all bask in the secure
-knowledge that we're better than the average person (let's face it,
-nobody ever believes that they're average or below-average), we should
-also admit that we're not the sharpest knife around, and there will be
-other people that are less of an idiot that you are.
-
-Some people react badly to smart people. Others take advantage of them.
-
-Make sure that you, as a kernel maintainer, are in the second group.
-Suck up to them, because they are the people who will make your job
-easier. In particular, they'll be able to make your decisions for you,
-which is what the game is all about.
-
-So when you find somebody smarter than you are, just coast along. Your
-management responsibilities largely become ones of saying "Sounds like a
-good idea - go wild", or "That sounds good, but what about xxx?". The
-second version in particular is a great way to either learn something
-new about "xxx" or seem _extra_ managerial by pointing out something the
-smarter person hadn't thought about. In either case, you win.
-
-One thing to look out for is to realize that greatness in one area does
-not necessarily translate to other areas. So you might prod people in
-specific directions, but let's face it, they might be good at what they
-do, and suck at everything else. The good news is that people tend to
-naturally gravitate back to what they are good at, so it's not like you
-are doing something irreversible when you _do_ prod them in some
-direction, just don't push too hard.
-
-
- Chapter 4: Placing blame
-
-Things will go wrong, and people want somebody to blame. Tag, you're it.
-
-It's not actually that hard to accept the blame, especially if people
-kind of realize that it wasn't _all_ your fault. Which brings us to the
-best way of taking the blame: do it for another guy. You'll feel good
-for taking the fall, he'll feel good about not getting blamed, and the
-guy who lost his whole 36GB porn-collection because of your incompetence
-will grudgingly admit that you at least didn't try to weasel out of it.
-
-Then make the developer who really screwed up (if you can find him) know
-_in_private_ that he screwed up. Not just so he can avoid it in the
-future, but so that he knows he owes you one. And, perhaps even more
-importantly, he's also likely the person who can fix it. Because, let's
-face it, it sure ain't you.
-
-Taking the blame is also why you get to be manager in the first place.
-It's part of what makes people trust you, and allow you the potential
-glory, because you're the one who gets to say "I screwed up". And if
-you've followed the previous rules, you'll be pretty good at saying that
-by now.
-
-
- Chapter 5: Things to avoid
-
-There's one thing people hate even more than being called "d*ckhead",
-and that is being called a "d*ckhead" in a sanctimonious voice. The
-first you can apologize for, the second one you won't really get the
-chance. They likely will no longer be listening even if you otherwise
-do a good job.
-
-We all think we're better than anybody else, which means that when
-somebody else puts on airs, it _really_ rubs us the wrong way. You may
-be morally and intellectually superior to everybody around you, but
-don't try to make it too obvious unless you really _intend_ to irritate
-somebody (*).
-
-Similarly, don't be too polite or subtle about things. Politeness easily
-ends up going overboard and hiding the problem, and as they say, "On the
-internet, nobody can hear you being subtle". Use a big blunt object to
-hammer the point in, because you can't really depend on people getting
-your point otherwise.
-
-Some humor can help pad both the bluntness and the moralizing. Going
-overboard to the point of being ridiculous can drive a point home
-without making it painful to the recipient, who just thinks you're being
-silly. It can thus help get through the personal mental block we all
-have about criticism.
-
-(*) Hint: internet newsgroups that are not directly related to your work
-are great ways to take out your frustrations at other people. Write
-insulting posts with a sneer just to get into a good flame every once in
-a while, and you'll feel cleansed. Just don't crap too close to home.
-
-
- Chapter 6: Why me?
-
-Since your main responsibility seems to be to take the blame for other
-peoples mistakes, and make it painfully obvious to everybody else that
-you're incompetent, the obvious question becomes one of why do it in the
-first place?
-
-First off, while you may or may not get screaming teenage girls (or
-boys, let's not be judgmental or sexist here) knocking on your dressing
-room door, you _will_ get an immense feeling of personal accomplishment
-for being "in charge". Never mind the fact that you're really leading
-by trying to keep up with everybody else and running after them as fast
-as you can. Everybody will still think you're the person in charge.
-
-It's a great job if you can hack it.

-Read the F-ing Papers!
-
-
-This document describes RCU-related publications, and is followed by
-the corresponding bibtex entries.
-
-The first thing resembling RCU was published in 1980, when Kung and Lehman
-[Kung80] recommended use of a garbage collector to defer destruction
-of nodes in a parallel binary search tree in order to simplify its
-implementation. This works well in environments that have garbage
-collectors, but current production garbage collectors incur significant
-read-side overhead.
-
-In 1982, Manber and Ladner [Manber82,Manber84] recommended deferring
-destruction until all threads running at that time have terminated, again
-for a parallel binary search tree. This approach works well in systems
-with short-lived threads, such as the K42 research operating system.
-However, Linux has long-lived tasks, so more is needed.
-
-In 1986, Hennessy, Osisek, and Seigh [Hennessy89] introduced passive
-serialization, which is an RCU-like mechanism that relies on the presence
-of "quiescent states" in the VM/XA hypervisor that are guaranteed not
-to be referencing the data structure. However, this mechanism was not
-optimized for modern computer systems, which is not surprising given
-that these overheads were not so expensive in the mid-80s. Nonetheless,
-passive serialization appears to be the first deferred-destruction
-mechanism to be used in production. Furthermore, the relevant patent has
-lapsed, so this approach may be used in non-GPL software, if desired.
-(In contrast, use of RCU is permitted only in software licensed under
-GPL. Sorry!!!)
-
-In 1990, Pugh [Pugh90] noted that explicitly tracking which threads
-were reading a given data structure permitted deferred free to operate
-in the presence of non-terminating threads. However, this explicit
-tracking imposes significant read-side overhead, which is undesirable
-in read-mostly situations. This algorithm does take pains to avoid
-write-side contention and parallelize the other write-side overheads by
-providing a fine-grained locking design, however, it would be interesting
-to see how much of the performance advantage reported in 1990 remains
-in 2004.
-
-At about this same time, Adams [Adams91] described ``chaotic relaxation'',
-where the normal barriers between successive iterations of convergent
-numerical algorithms are relaxed, so that iteration $n$ might use
-data from iteration $n-1$ or even $n-2$. This introduces error,
-which typically slows convergence and thus increases the number of
-iterations required. However, this increase is sometimes more than made
-up for by a reduction in the number of expensive barrier operations,
-which are otherwise required to synchronize the threads at the end
-of each iteration. Unfortunately, chaotic relaxation requires highly
-structured data, such as the matrices used in scientific programs, and
-is thus inapplicable to most data structures in operating-system kernels.
-
-In 1993, Jacobson [Jacobson93] verbally described what is perhaps the
-simplest deferred-free technique: simply waiting a fixed amount of time
-before freeing blocks awaiting deferred free. Jacobson did not describe
-any write-side changes he might have made in this work using SGI's Irix
-kernel. Aju John published a similar technique in 1995 [AjuJohn95].
-This works well if there is a well-defined upper bound on the length of
-time that reading threads can hold references, as there might well be in
-hard real-time systems. However, if this time is exceeded, perhaps due
-to preemption, excessive interrupts, or larger-than-anticipated load,
-memory corruption can ensue, with no reasonable means of diagnosis.
-Jacobson's technique is therefore inappropriate for use in production
-operating-system kernels, except when such kernels can provide hard
-real-time response guarantees for all operations.
-
-Also in 1995, Pu et al. [Pu95a] applied a technique similar to that of Pugh's
-read-side-tracking to permit replugging of algorithms within a commercial
-Unix operating system. However, this replugging permitted only a single
-reader at a time. The following year, this same group of researchers
-extended their technique to allow for multiple readers [Cowan96a].
-Their approach requires memory barriers (and thus pipeline stalls),
-but reduces memory latency, contention, and locking overheads.
-
-1995 also saw the first publication of DYNIX/ptx's RCU mechanism
-[Slingwine95], which was optimized for modern CPU architectures,
-and was successfully applied to a number of situations within the
-DYNIX/ptx kernel. The corresponding conference paper appeared in 1998
-[McKenney98].
-
-In 1999, the Tornado and K42 groups described their "generations"
-mechanism, which quite similar to RCU [Gamsa99]. These operating systems
-made pervasive use of RCU in place of "existence locks", which greatly
-simplifies locking hierarchies.
-
-2001 saw the first RCU presentation involving Linux [McKenney01a]
-at OLS. The resulting abundance of RCU patches was presented the
-following year [McKenney02a], and use of RCU in dcache was first
-described that same year [Linder02a].
-
-Also in 2002, Michael [Michael02b,Michael02a] presented techniques
-that defer the destruction of data structures to simplify non-blocking
-synchronization (wait-free synchronization, lock-free synchronization,
-and obstruction-free synchronization are all examples of non-blocking
-synchronization). In particular, this technique eliminates locking,
-reduces contention, reduces memory latency for readers, and parallelizes
-pipeline stalls and memory latency for writers. However, these
-techniques still impose significant read-side overhead in the form of
-memory barriers. Researchers at Sun worked along similar lines in the
-same timeframe [HerlihyLM02,HerlihyLMS03].
-
-In 2003, the K42 group described how RCU could be used to create
-hot-pluggable implementations of operating-system functions. Later that
-year saw a paper describing an RCU implementation of System V IPC
-[Arcangeli03], and an introduction to RCU in Linux Journal [McKenney03a].
-
-2004 has seen a Linux-Journal article on use of RCU in dcache
-[McKenney04a], a performance comparison of locking to RCU on several
-different CPUs [McKenney04b], a dissertation describing use of RCU in a
-number of operating-system kernels [PaulEdwardMcKenneyPhD], and a paper
-describing how to make RCU safe for soft-realtime applications [Sarma04c].

-RCU on Uniprocessor Systems
-
-
-A common misconception is that, on UP systems, the call_rcu() primitive
-may immediately invoke its function, and that the synchronize_kernel
-primitive may return immediately. The basis of this misconception
-is that since there is only one CPU, it should not be necessary to
-wait for anything else to get done, since there are no other CPUs for
-anything else to be happening on. Although this approach will sort of
-work a surprising amount of the time, it is a very bad idea in general.
-This document presents two examples that demonstrate exactly how bad an
-idea this is.
-
-
-Example 1: softirq Suicide
-
-Suppose that an RCU-based algorithm scans a linked list containing
-elements A, B, and C in process context, and can delete elements from
-this same list in softirq context. Suppose that the process-context scan
-is referencing element B when it is interrupted by softirq processing,
-which deletes element B, and then invokes call_rcu() to free element B
-after a grace period.
-
-Now, if call_rcu() were to directly invoke its arguments, then upon return
-from softirq, the list scan would find itself referencing a newly freed
-element B. This situation can greatly decrease the life expectancy of
-your kernel.
-
-
-Example 2: Function-Call Fatality
-
-Of course, one could avert the suicide described in the preceding example
-by having call_rcu() directly invoke its arguments only if it was called
-from process context. However, this can fail in a similar manner.
-
-Suppose that an RCU-based algorithm again scans a linked list containing
-elements A, B, and C in process contexts, but that it invokes a function
-on each element as it is scanned. Suppose further that this function
-deletes element B from the list, then passes it to call_rcu() for deferred
-freeing. This may be a bit unconventional, but it is perfectly legal
-RCU usage, since call_rcu() must wait for a grace period to elapse.
-Therefore, in this case, allowing call_rcu() to immediately invoke
-its arguments would cause it to fail to make the fundamental guarantee
-underlying RCU, namely that call_rcu() defers invoking its arguments until
-all RCU read-side critical sections currently executing have completed.
-
-Quick Quiz: why is it -not- legal to invoke synchronize_kernel() in
-this case?
-
-
-Summary
-
-Permitting call_rcu() to immediately invoke its arguments or permitting
-synchronize_kernel() to immediately return breaks RCU, even on a UP system.
-So do not do it! Even on a UP system, the RCU infrastructure -must-
-respect grace periods.
-
-
-Answer to Quick Quiz
-
-The calling function is scanning an RCU-protected linked list, and
-is therefore within an RCU read-side critical section. Therefore,
-the called function has been invoked within an RCU read-side critical
-section, and is not permitted to block.

-Using RCU to Protect Read-Mostly Arrays
-
-
-Although RCU is more commonly used to protect linked lists, it can
-also be used to protect arrays. Three situations are as follows:
-
-1. Hash Tables
-
-2. Static Arrays
-
-3. Resizeable Arrays
-
-Each of these situations are discussed below.
-
-
-Situation 1: Hash Tables
-
-Hash tables are often implemented as an array, where each array entry
-has a linked-list hash chain. Each hash chain can be protected by RCU
-as described in the listRCU.txt document. This approach also applies
-to other array-of-list situations, such as radix trees.
-
-
-Situation 2: Static Arrays
-
-Static arrays, where the data (rather than a pointer to the data) is
-located in each array element, and where the array is never resized,
-have not been used with RCU. Rik van Riel recommends using seqlock in
-this situation, which would also have minimal read-side overhead as long
-as updates are rare.
-
-Quick Quiz: Why is it so important that updates be rare when
- using seqlock?
-
-
-Situation 3: Resizeable Arrays
-
-Use of RCU for resizeable arrays is demonstrated by the grow_ary()
-function used by the System V IPC code. The array is used to map from
-semaphore, message-queue, and shared-memory IDs to the data structure
-that represents the corresponding IPC construct. The grow_ary()
-function does not acquire any locks; instead its caller must hold the
-ids->sem semaphore.
-
-The grow_ary() function, shown below, does some limit checks, allocates a
-new ipc_id_ary, copies the old to the new portion of the new, initializes
-the remainder of the new, updates the ids->entries pointer to point to
-the new array, and invokes ipc_rcu_putref() to free up the old array.
-Note that rcu_assign_pointer() is used to update the ids->entries pointer,
-which includes any memory barriers required on whatever architecture
-you are running on.
-
- static int grow_ary(struct ipc_ids* ids, int newsize)
- {
- struct ipc_id_ary* new;
- struct ipc_id_ary* old;
- int i;
- int size = ids->entries->size;
-
- if(newsize > IPCMNI)
- newsize = IPCMNI;
- if(newsize <= size)
- return newsize;
-
- new = ipc_rcu_alloc(sizeof(struct kern_ipc_perm *)*newsize +
- sizeof(struct ipc_id_ary));
- if(new == NULL)
- return size;
- new->size = newsize;
- memcpy(new->p, ids->entries->p,
- sizeof(struct kern_ipc_perm *)*size +
- sizeof(struct ipc_id_ary));
- for(i=size;i<newsize;i++) {
- new->p[i] = NULL;
- }
- old = ids->entries;
-
- /*
- * Use rcu_assign_pointer() to make sure the memcpyed
- * contents of the new array are visible before the new
- * array becomes visible.
- */
- rcu_assign_pointer(ids->entries, new);
-
- ipc_rcu_putref(old);
- return newsize;
- }
-
-The ipc_rcu_putref() function decrements the array's reference count
-and then, if the reference count has dropped to zero, uses call_rcu()
-to free the array after a grace period has elapsed.
-
-The array is traversed by the ipc_lock() function. This function
-indexes into the array under the protection of rcu_read_lock(),
-using rcu_dereference() to pick up the pointer to the array so
-that it may later safely be dereferenced -- memory barriers are
-required on the Alpha CPU. Since the size of the array is stored
-with the array itself, there can be no array-size mismatches, so
-a simple check suffices. The pointer to the structure corresponding
-to the desired IPC object is placed in "out", with NULL indicating
-a non-existent entry. After acquiring "out->lock", the "out->deleted"
-flag indicates whether the IPC object is in the process of being
-deleted, and, if not, the pointer is returned.
-
- struct kern_ipc_perm* ipc_lock(struct ipc_ids* ids, int id)
- {
- struct kern_ipc_perm* out;
- int lid = id % SEQ_MULTIPLIER;
- struct ipc_id_ary* entries;
-
- rcu_read_lock();
- entries = rcu_dereference(ids->entries);
- if(lid >= entries->size) {
- rcu_read_unlock();
- return NULL;
- }
- out = entries->p[lid];
- if(out == NULL) {
- rcu_read_unlock();
- return NULL;
- }
- spin_lock(&out->lock);
-
- /* ipc_rmid() may have already freed the ID while ipc_lock
- * was spinning: here verify that the structure is still valid
- */
- if (out->deleted) {
- spin_unlock(&out->lock);
- rcu_read_unlock();
- return NULL;
- }
- return out;
- }
-
-
-Answer to Quick Quiz:
-
- The reason that it is important that updates be rare when
- using seqlock is that frequent updates can livelock readers.
- One way to avoid this problem is to assign a seqlock for
- each array entry rather than to the entire array.

-Review Checklist for RCU Patches
-
-
-This document contains a checklist for producing and reviewing patches
-that make use of RCU. Violating any of the rules listed below will
-result in the same sorts of problems that leaving out a locking primitive
-would cause. This list is based on experiences reviewing such patches
-over a rather long period of time, but improvements are always welcome!
-
-0. Is RCU being applied to a read-mostly situation? If the data
- structure is updated more than about 10% of the time, then
- you should strongly consider some other approach, unless
- detailed performance measurements show that RCU is nonetheless
- the right tool for the job.
-
- The other exception would be where performance is not an issue,
- and RCU provides a simpler implementation. An example of this
- situation is the dynamic NMI code in the Linux 2.6 kernel,
- at least on architectures where NMIs are rare.
-
-1. Does the update code have proper mutual exclusion?
-
- RCU does allow -readers- to run (almost) naked, but -writers- must
- still use some sort of mutual exclusion, such as:
-
- a. locking,
- b. atomic operations, or
- c. restricting updates to a single task.
-
- If you choose #b, be prepared to describe how you have handled
- memory barriers on weakly ordered machines (pretty much all of
- them -- even x86 allows reads to be reordered), and be prepared
- to explain why this added complexity is worthwhile. If you
- choose #c, be prepared to explain how this single task does not
- become a major bottleneck on big multiprocessor machines.
-
-2. Do the RCU read-side critical sections make proper use of
- rcu_read_lock() and friends? These primitives are needed
- to suppress preemption (or bottom halves, in the case of
- rcu_read_lock_bh()) in the read-side critical sections,
- and are also an excellent aid to readability.
-
-3. Does the update code tolerate concurrent accesses?
-
- The whole point of RCU is to permit readers to run without
- any locks or atomic operations. This means that readers will
- be running while updates are in progress. There are a number
- of ways to handle this concurrency, depending on the situation:
-
- a. Make updates appear atomic to readers. For example,
- pointer updates to properly aligned fields will appear
- atomic, as will individual atomic primitives. Operations
- performed under a lock and sequences of multiple atomic
- primitives will -not- appear to be atomic.
-
- This is almost always the best approach.
-
- b. Carefully order the updates and the reads so that
- readers see valid data at all phases of the update.
- This is often more difficult than it sounds, especially
- given modern CPUs' tendency to reorder memory references.
- One must usually liberally sprinkle memory barriers
- (smp_wmb(), smp_rmb(), smp_mb()) through the code,
- making it difficult to understand and to test.
-
- It is usually better to group the changing data into
- a separate structure, so that the change may be made
- to appear atomic by updating a pointer to reference
- a new structure containing updated values.
-
-4. Weakly ordered CPUs pose special challenges. Almost all CPUs
- are weakly ordered -- even i386 CPUs allow reads to be reordered.
- RCU code must take all of the following measures to prevent
- memory-corruption problems:
-
- a. Readers must maintain proper ordering of their memory
- accesses. The rcu_dereference() primitive ensures that
- the CPU picks up the pointer before it picks up the data
- that the pointer points to. This really is necessary
- on Alpha CPUs. If you don't believe me, see:
-
- http://www.openvms.compaq.com/wizard/wiz_2637.html
-
- The rcu_dereference() primitive is also an excellent
- documentation aid, letting the person reading the code
- know exactly which pointers are protected by RCU.
-
- The rcu_dereference() primitive is used by the various
- "_rcu()" list-traversal primitives, such as the
- list_for_each_entry_rcu().
-
- b. If the list macros are being used, the list_del_rcu(),
- list_add_tail_rcu(), and list_del_rcu() primitives must
- be used in order to prevent weakly ordered machines from
- misordering structure initialization and pointer planting.
- Similarly, if the hlist macros are being used, the
- hlist_del_rcu() and hlist_add_head_rcu() primitives
- are required.
-
- c. Updates must ensure that initialization of a given
- structure happens before pointers to that structure are
- publicized. Use the rcu_assign_pointer() primitive
- when publicizing a pointer to a structure that can
- be traversed by an RCU read-side critical section.
-
- [The rcu_assign_pointer() primitive is in process.]
-
-5. If call_rcu(), or a related primitive such as call_rcu_bh(),
- is used, the callback function must be written to be called
- from softirq context. In particular, it cannot block.
-
-6. Since synchronize_kernel() blocks, it cannot be called from
- any sort of irq context.
-
-7. If the updater uses call_rcu(), then the corresponding readers
- must use rcu_read_lock() and rcu_read_unlock(). If the updater
- uses call_rcu_bh(), then the corresponding readers must use
- rcu_read_lock_bh() and rcu_read_unlock_bh(). Mixing things up
- will result in confusion and broken kernels.
-
- One exception to this rule: rcu_read_lock() and rcu_read_unlock()
- may be substituted for rcu_read_lock_bh() and rcu_read_unlock_bh()
- in cases where local bottom halves are already known to be
- disabled, for example, in irq or softirq context. Commenting
- such cases is a must, of course! And the jury is still out on
- whether the increased speed is worth it.
-
-8. Although synchronize_kernel() is a bit slower than is call_rcu(),
- it usually results in simpler code. So, unless update performance
- is important or the updaters cannot block, synchronize_kernel()
- should be used in preference to call_rcu().
-
-9. All RCU list-traversal primitives, which include
- list_for_each_rcu(), list_for_each_entry_rcu(),
- list_for_each_continue_rcu(), and list_for_each_safe_rcu(),
- must be within an RCU read-side critical section. RCU
- read-side critical sections are delimited by rcu_read_lock()
- and rcu_read_unlock(), or by similar primitives such as
- rcu_read_lock_bh() and rcu_read_unlock_bh().
-
- Use of the _rcu() list-traversal primitives outside of an
- RCU read-side critical section causes no harm other than
- a slight performance degradation on Alpha CPUs and some
- confusion on the part of people trying to read the code.
-
- Another way of thinking of this is "If you are holding the
- lock that prevents the data structure from changing, why do
- you also need RCU-based protection?" That said, there may
- well be situations where use of the _rcu() list-traversal
- primitives while the update-side lock is held results in
- simpler and more maintainable code. The jury is still out
- on this question.
-
-10. Conversely, if you are in an RCU read-side critical section,
- you -must- use the "_rcu()" variants of the list macros.
- Failing to do so will break Alpha and confuse people reading
- your code.

-Using RCU to Protect Read-Mostly Linked Lists
-
-
-One of the best applications of RCU is to protect read-mostly linked lists
-("struct list_head" in list.h). One big advantage of this approach
-is that all of the required memory barriers are included for you in
-the list macros. This document describes several applications of RCU,
-with the best fits first.
-
-
-Example 1: Read-Side Action Taken Outside of Lock, No In-Place Updates
-
-The best applications are cases where, if reader-writer locking were
-used, the read-side lock would be dropped before taking any action
-based on the results of the search. The most celebrated example is
-the routing table. Because the routing table is tracking the state of
-equipment outside of the computer, it will at times contain stale data.
-Therefore, once the route has been computed, there is no need to hold
-the routing table static during transmission of the packet. After all,
-you can hold the routing table static all you want, but that won't keep
-the external Internet from changing, and it is the state of the external
-Internet that really matters. In addition, routing entries are typically
-added or deleted, rather than being modified in place.
-
-A straightforward example of this use of RCU may be found in the
-system-call auditing support. For example, a reader-writer locked
-implementation of audit_filter_task() might be as follows:
-
- static enum audit_state audit_filter_task(struct task_struct *tsk)
- {
- struct audit_entry *e;
- enum audit_state state;
-
- read_lock(&auditsc_lock);
- list_for_each_entry(e, &audit_tsklist, list) {
- if (audit_filter_rules(tsk, &e->rule, NULL, &state)) {
- read_unlock(&auditsc_lock);
- return state;
- }
- }
- read_unlock(&auditsc_lock);
- return AUDIT_BUILD_CONTEXT;
- }
-
-Here the list is searched under the lock, but the lock is dropped before
-the corresponding value is returned. By the time that this value is acted
-on, the list may well have been modified. This makes sense, since if
-you are turning auditing off, it is OK to audit a few extra system calls.
-
-This means that RCU can be easily applied to the read side, as follows:
-
- static enum audit_state audit_filter_task(struct task_struct *tsk)
- {
- struct audit_entry *e;
- enum audit_state state;
-
- rcu_read_lock();
- list_for_each_entry_rcu(e, &audit_tsklist, list) {
- if (audit_filter_rules(tsk, &e->rule, NULL, &state)) {
- rcu_read_unlock();
- return state;
- }
- }
- rcu_read_unlock();
- return AUDIT_BUILD_CONTEXT;
- }
-
-The read_lock() and read_unlock() calls have become rcu_read_lock()
-and rcu_read_unlock(), respectively, and the list_for_each_entry() has
-become list_for_each_entry_rcu(). The _rcu() list-traversal primitives
-insert the read-side memory barriers that are required on DEC Alpha CPUs.
-
-The changes to the update side are also straightforward. A reader-writer
-lock might be used as follows for deletion and insertion:
-
- static inline int audit_del_rule(struct audit_rule *rule,
- struct list_head *list)
- {
- struct audit_entry *e;
-
- write_lock(&auditsc_lock);
- list_for_each_entry(e, list, list) {
- if (!audit_compare_rule(rule, &e->rule)) {
- list_del(&e->list);
- call_rcu(&e->rcu, audit_free_rule, e);
- return 0;
- }
- }
- write_unlock(&auditsc_lock);
- return -EFAULT; /* No matching rule */
- }
-
- static inline int audit_add_rule(struct audit_entry *entry,
- struct list_head *list)
- {
- write_lock(&auditsc_lock);
- if (entry->rule.flags & AUDIT_PREPEND) {
- entry->rule.flags &= ~AUDIT_PREPEND;
- list_add(&entry->list, list);
- } else {
- list_add_tail(&entry->list, list);
- }
- write_unlock(&auditsc_lock);
- return 0;
- }
-
-Following are the RCU equivalents for these two functions:
-
- static inline int audit_del_rule(struct audit_rule *rule,
- struct list_head *list)
- {
- struct audit_entry *e;
-
- /* Do not use the _rcu iterator here, since this is the only
- * deletion routine. */
- list_for_each_entry(e, list, list) {
- if (!audit_compare_rule(rule, &e->rule)) {
- list_del_rcu(&e->list);
- call_rcu(&e->rcu, audit_free_rule, e);
- return 0;
- }
- }
- return -EFAULT; /* No matching rule */
- }
-
- static inline int audit_add_rule(struct audit_entry *entry,
- struct list_head *list)
- {
- if (entry->rule.flags & AUDIT_PREPEND) {
- entry->rule.flags &= ~AUDIT_PREPEND;
- list_add_rcu(&entry->list, list);
- } else {
- list_add_tail_rcu(&entry->list, list);
- }
- return 0;
- }
-
-Normally, the write_lock() and write_unlock() would be replaced by
-a spin_lock() and a spin_unlock(), but in this case, all callers hold
-audit_netlink_sem, so no additional locking is required. The auditsc_lock
-can therefore be eliminated, since use of RCU eliminates the need for
-writers to exclude readers.
-
-The list_del(), list_add(), and list_add_tail() primitives have been
-replaced by list_del_rcu(), list_add_rcu(), and list_add_tail_rcu().
-The _rcu() list-manipulation primitives add memory barriers that are
-needed on weakly ordered CPUs (most of them!).
-
-So, when readers can tolerate stale data and when entries are either added
-or deleted, without in-place modification, it is very easy to use RCU!
-
-
-Example 2: Handling In-Place Updates
-
-The system-call auditing code does not update auditing rules in place.
-However, if it did, reader-writer-locked code to do so might look as
-follows (presumably, the field_count is only permitted to decrease,
-otherwise, the added fields would need to be filled in):
-
- static inline int audit_upd_rule(struct audit_rule *rule,
- struct list_head *list,
- __u32 newaction,
- __u32 newfield_count)
- {
- struct audit_entry *e;
- struct audit_newentry *ne;
-
- write_lock(&auditsc_lock);
- list_for_each_entry(e, list, list) {
- if (!audit_compare_rule(rule, &e->rule)) {
- e->rule.action = newaction;
- e->rule.file_count = newfield_count;
- write_unlock(&auditsc_lock);
- return 0;
- }
- }
- write_unlock(&auditsc_lock);
- return -EFAULT; /* No matching rule */
- }
-
-The RCU version creates a copy, updates the copy, then replaces the old
-entry with the newly updated entry. This sequence of actions, allowing
-concurrent reads while doing a copy to perform an update, is what gives
-RCU ("read-copy update") its name. The RCU code is as follows:
-
- static inline int audit_upd_rule(struct audit_rule *rule,
- struct list_head *list,
- __u32 newaction,
- __u32 newfield_count)
- {
- struct audit_entry *e;
- struct audit_newentry *ne;
-
- list_for_each_entry(e, list, list) {
- if (!audit_compare_rule(rule, &e->rule)) {
- ne = kmalloc(sizeof(*entry), GFP_ATOMIC);
- if (ne == NULL)
- return -ENOMEM;
- audit_copy_rule(&ne->rule, &e->rule);
- ne->rule.action = newaction;
- ne->rule.file_count = newfield_count;
- list_add_rcu(ne, e);
- list_del(e);
- call_rcu(&e->rcu, audit_free_rule, e);
- return 0;
- }
- }
- return -EFAULT; /* No matching rule */
- }
-
-Again, this assumes that the caller holds audit_netlink_sem. Normally,
-the reader-writer lock would become a spinlock in this sort of code.
-
-
-Example 3: Eliminating Stale Data
-
-The auditing examples above tolerate stale data, as do most algorithms
-that are tracking external state. Because there is a delay from the
-time the external state changes before Linux becomes aware of the change,
-additional RCU-induced staleness is normally not a problem.
-
-However, there are many examples where stale data cannot be tolerated.
-One example in the Linux kernel is the System V IPC (see the ipc_lock()
-function in ipc/util.c). This code checks a "deleted" flag under a
-per-entry spinlock, and, if the "deleted" flag is set, pretends that the
-entry does not exist. For this to be helpful, the search function must
-return holding the per-entry spinlock, as ipc_lock() does in fact do.
-
-Quick Quiz: Why does the search function need to return holding the
-per-entry lock for this deleted-flag technique to be helpful?
-
-If the system-call audit module were to ever need to reject stale data,
-one way to accomplish this would be to add a "deleted" flag and a "lock"
-spinlock to the audit_entry structure, and modify audit_filter_task()
-as follows:
-
- static enum audit_state audit_filter_task(struct task_struct *tsk)
- {
- struct audit_entry *e;
- enum audit_state state;
-
- rcu_read_lock();
- list_for_each_entry_rcu(e, &audit_tsklist, list) {
- if (audit_filter_rules(tsk, &e->rule, NULL, &state)) {
- spin_lock(&e->lock);
- if (e->deleted) {
- spin_unlock(&e->lock);
- rcu_read_unlock();
- return AUDIT_BUILD_CONTEXT;
- }
- rcu_read_unlock();
- return state;
- }
- }
- rcu_read_unlock();
- return AUDIT_BUILD_CONTEXT;
- }
-
-Note that this example assumes that entries are only added and deleted.
-Additional mechanism is required to deal correctly with the
-update-in-place performed by audit_upd_rule(). For one thing,
-audit_upd_rule() would need additional memory barriers to ensure
-that the list_add_rcu() was really executed before the list_del_rcu().
-
-The audit_del_rule() function would need to set the "deleted"
-flag under the spinlock as follows:
-
- static inline int audit_del_rule(struct audit_rule *rule,
- struct list_head *list)
- {
- struct audit_entry *e;
-
- /* Do not use the _rcu iterator here, since this is the only
- * deletion routine. */
- list_for_each_entry(e, list, list) {
- if (!audit_compare_rule(rule, &e->rule)) {
- spin_lock(&e->lock);
- list_del_rcu(&e->list);
- e->deleted = 1;
- spin_unlock(&e->lock);
- call_rcu(&e->rcu, audit_free_rule, e);
- return 0;
- }
- }
- return -EFAULT; /* No matching rule */
- }
-
-
-Summary
-
-Read-mostly list-based data structures that can tolerate stale data are
-the most amenable to use of RCU. The simplest case is where entries are
-either added or deleted from the data structure (or atomically modified
-in place), but non-atomic in-place modifications can be handled by making
-a copy, updating the copy, then replacing the original with the copy.
-If stale data cannot be tolerated, then a "deleted" flag may be used
-in conjunction with a per-entry spinlock in order to allow the search
-function to reject newly deleted data.
-
-
-Answer to Quick Quiz
-
-If the search function drops the per-entry lock before returning, then
-the caller will be processing stale data in any case. If it is really
-OK to be processing stale data, then you don't need a "deleted" flag.
-If processing stale data really is a problem, then you need to hold the
-per-entry lock across all of the code that uses the value looked up.

-RCU Concepts
-
-
-The basic idea behind RCU (read-copy update) is to split destructive
-operations into two parts, one that prevents anyone from seeing the data
-item being destroyed, and one that actually carries out the destruction.
-A "grace period" must elapse between the two parts, and this grace period
-must be long enough that any readers accessing the item being deleted have
-since dropped their references. For example, an RCU-protected deletion
-from a linked list would first remove the item from the list, wait for
-a grace period to elapse, then free the element. See the listRCU.txt
-file for more information on using RCU with linked lists.
-
-
-Frequently Asked Questions
-
-o Why would anyone want to use RCU?
-
- The advantage of RCU's two-part approach is that RCU readers need
- not acquire any locks, perform any atomic instructions, write to
- shared memory, or (on CPUs other than Alpha) execute any memory
- barriers. The fact that these operations are quite expensive
- on modern CPUs is what gives RCU its performance advantages
- in read-mostly situations. The fact that RCU readers need not
- acquire locks can also greatly simplify deadlock-avoidance code.
-
-o How can the updater tell when a grace period has completed
- if the RCU readers give no indication when they are done?
-
- Just as with spinlocks, RCU readers are not permitted to
- block, switch to user-mode execution, or enter the idle loop.
- Therefore, as soon as a CPU is seen passing through any of these
- three states, we know that that CPU has exited any previous RCU
- read-side critical sections. So, if we remove an item from a
- linked list, and then wait until all CPUs have switched context,
- executed in user mode, or executed in the idle loop, we can
- safely free up that item.
-
-o If I am running on a uniprocessor kernel, which can only do one
- thing at a time, why should I wait for a grace period?
-
- See the UP.txt file in this directory.
-
-o How can I see where RCU is currently used in the Linux kernel?
-
- Search for "rcu_read_lock", "call_rcu", and "synchronize_kernel".
-
-o What guidelines should I follow when writing code that uses RCU?
-
- See the checklist.txt file in this directory.
-
-o Why the name "RCU"?
-
- "RCU" stands for "read-copy update". The file listRCU.txt has
- more information on where this name came from, search for
- "read-copy update" to find it.
-
-o I hear that RCU is patented? What is with that?
-
- Yes, it is. There are several known patents related to RCU,
- search for the string "Patent" in RTFP.txt to find them.
- Of these, one was allowed to lapse by the assignee, and the
- others have been contributed to the Linux kernel under GPL.
-
-o Where can I find more information on RCU?
-
- See the RTFP.txt file in this directory.

-Release Notes for Linux on Intel's IXP2000 Network Processor
-
-Maintained by Deepak Saxena <dsaxena@plexity.net>
--------------------------------------------------------------------------
-
-1. Overview
-
-Intel's IXP2000 family of NPUs (IXP2400, IXP2800, IXP2850) is designed
-for high-performance network applications such high-availability
-telecom systems. In addition to an XScale core, it contains up to 8
-"MicroEngines" that run special code, several high-end networking
-interfaces (UTOPIA, SPI, etc), a PCI host bridge, one serial port,
-flash interface, and some other odds and ends. For more information, see:
-
-http://developer.intel.com/design/network/products/npfamily/ixp2xxx.htm
-
-2. Linux Support
-
-Linux currently supports the following features on the IXP2000 NPUS:
-
-- On-chip serial
-- PCI
-- Flash (MTD/JFFS2)
-- I2C through GPIO
-- Timers (watchdog, OS)
-
-That is about all we can support under Linux ATM b/c the core networking
-components of the chip are accessed via Intel's closed source SDK.
-Please contact Intel directly on issues with using those. There is
-also a mailing list run by some folks at Princeton University that might
-be of helpful: https://lists.cs.princeton.edu/mailman/listinfo/ixp2xxx
-
-WHATEVER YOU DO, DO NOT POST EMAIL TO THE LINUX-ARM OR LINUX-ARM-KERNEL
-MAILINNG LISTS REGARDING THE INTEL SDK.
-
-3. Supported Platforms
-
-- Intel IXDP2400 Reference Platform
-- Intel IXDP2800 Reference Platform
-- Intel IXDP2401 Reference Platform
-- Intel IXDP2801 Reference Platform
-- RadiSys ENP-2611
-
-4. Usage Notes
-
-- The IXP2000 platforms ususally have rather complex PCI bus topologies
- with large memory space requirements. In addition, b/c of the way the
- Intel SDK is designed, devices are enumerated in a vert specific
- way. B/c of this this, we use "pci=firmware" option in the kernel
- command line so that we do not re-enumerate the bus.
-
-- IXDP2x01 systems have variable clock tick rates that we cannot determine
- via HW registers. The "ixdp2x01_clk=XXX" cmd line options allows you
- to pass the clock rate to the board port.
-

- S3C2410 GPIO Control
- ====================
-
-Introduction
-------------
-
- The s3c2410 kernel provides an interface to configure and
- manipulate the state of the GPIO pins, and find out other
- information about them.
-
- There are a number of conditions attached to the configuration
- of the s3c2410 GPIO system, please read the Samsung provided
- data-sheet/users manual to find out the complete list.
-
-
-Headers
--------
-
- See include/asm-arm/arch-s3c2410/regs-gpio.h for the list
- of GPIO pins, and the configuration values for them. This
- is included by using #include <asm/arch/regs-gpio.h>
-
- The GPIO management functions are defined in the hardware
- header include/asm-arm/arch-s3c2410/hardware.h which can be
- included by #include <asm/arch/hardware.h>
-
- A useful ammount of documentation can be found in the hardware
- header on how the GPIO functions (and others) work.
-
- Whilst a number of these functions do make some checks on what
- is passed to them, for speed of use, they may not always ensure
- that the user supplied data to them is correct.
-
-
-PIN Numbers
------------
-
- Each pin has an unique number associated with it in regs-gpio.h,
- eg S3C2410_GPA0 or S3C2410_GPF1. These defines are used to tell
- the GPIO functions which pin is to be used.
-
-
-Configuring a pin
------------------
-
- The following function allows the configuration of a given pin to
- be changed.
-
- void s3c2410_gpio_cfgpin(unsigned int pin, unsigned int function);
-
- Eg:
-
- s3c2410_gpio_cfgpin(S3C2410_GPA0, S3C2410_GPA0_ADDR0);
- s3c2410_gpio_cfgpin(S3C2410_GPE8, S3C2410_GPE8_SDDAT1);
-
- which would turn GPA0 into the lowest Address line A0, and set
- GPE8 to be connected to the SDIO/MMC controller's SDDAT1 line.
-
-
-Reading the current configuration
----------------------------------
-
- The current configuration of a pin can be read by using:
-
- s3c2410_gpio_getcfg(unsigned int pin);
-
- The return value will be from the same set of values which can be
- passed to s3c2410_gpio_cfgpin().
-
-
-Configuring a pull-up resistor
-------------------------------
-
- A large proportion of the GPIO pins on the S3C2410 can have weak
- pull-up resistors enabled. This can be configured by the following
- function:
-
- void s3c2410_gpio_pullup(unsigned int pin, unsigned int to);
-
- Where the to value is zero to set the pull-up off, and 1 to enable
- the specified pull-up. Any other values are currently undefined.
-
-
-Getting the state of a PIN
---------------------------
-
- The state of a pin can be read by using the function:
-
- unsigned int s3c2410_gpio_getpin(unsigned int pin);
-
- This will return either zero or non-zero. Do not count on this
- function returning 1 if the pin is set.
-
-
-Setting the state of a PIN
---------------------------
-
- The value an pin is outputing can be modified by using the following:
-
- void s3c2410_gpio_setpin(unsigned int pin, unsigned int to);
-
- Which sets the given pin to the value. Use 0 to write 0, and 1 to
- set the output to 1.
-
-
-Getting the IRQ number associated with a PIN
---------------------------------------------
-
- The following function can map the given pin number to an IRQ
- number to pass to the IRQ system.
-
- int s3c2410_gpio_getirq(unsigned int pin);
-
- Note, not all pins have an IRQ.

-Anticipatory IO scheduler
--------------------------
-Nick Piggin <piggin@cyberone.com.au> 13 Sep 2003
-
-Attention! Database servers, especially those using "TCQ" disks should
-investigate performance with the 'deadline' IO scheduler. Any system with high
-disk performance requirements should do so, in fact.
-
-If you see unusual performance characteristics of your disk systems, or you
-see big performance regressions versus the deadline scheduler, please email
-me. Database users don't bother unless you're willing to test a lot of patches
-from me ;) its a known issue.
-
-Also, users with hardware RAID controllers, doing striping, may find
-highly variable performance results with using the as-iosched. The
-as-iosched anticipatory implementation is based on the notion that a disk
-device has only one physical seeking head. A striped RAID controller
-actually has a head for each physical device in the logical RAID device.
-
-However, setting the antic_expire (see tunable parameters below) produces
-very similar behavior to the deadline IO scheduler.
-
-
-Selecting IO schedulers
------------------------
-To choose IO schedulers at boot time, use the argument 'elevator=deadline'.
-'noop' and 'as' (the default) are also available. IO schedulers are assigned
-globally at boot time only presently.
-
-
-Anticipatory IO scheduler Policies
-----------------------------------
-The as-iosched implementation implements several layers of policies
-to determine when an IO request is dispatched to the disk controller.
-Here are the policies outlined, in order of application.
-
-1. one-way Elevator algorithm.
-
-The elevator algorithm is similar to that used in deadline scheduler, with
-the addition that it allows limited backward movement of the elevator
-(i.e. seeks backwards). A seek backwards can occur when choosing between
-two IO requests where one is behind the elevator's current position, and
-the other is in front of the elevator's position. If the seek distance to
-the request in back of the elevator is less than half the seek distance to
-the request in front of the elevator, then the request in back can be chosen.
-Backward seeks are also limited to a maximum of MAXBACK (1024*1024) sectors.
-This favors forward movement of the elevator, while allowing opportunistic
-"short" backward seeks.
-
-2. FIFO expiration times for reads and for writes.
-
-This is again very similar to the deadline IO scheduler. The expiration
-times for requests on these lists is tunable using the parameters read_expire
-and write_expire discussed below. When a read or a write expires in this way,
-the IO scheduler will interrupt its current elevator sweep or read anticipation
-to service the expired request.
-
-3. Read and write request batching
-
-A batch is a collection of read requests or a collection of write
-requests. The as scheduler alternates dispatching read and write batches
-to the driver. In the case a read batch, the scheduler submits read
-requests to the driver as long as there are read requests to submit, and
-the read batch time limit has not been exceeded (read_batch_expire).
-The read batch time limit begins counting down only when there are
-competing write requests pending.
-
-In the case of a write batch, the scheduler submits write requests to
-the driver as long as there are write requests available, and the
-write batch time limit has not been exceeded (write_batch_expire).
-However, the length of write batches will be gradually shortened
-when read batches frequently exceed their time limit.
-
-When changing between batch types, the scheduler waits for all requests
-from the previous batch to complete before scheduling requests for the
-next batch.
-
-The read and write fifo expiration times described in policy 2 above
-are checked only when in scheduling IO of a batch for the corresponding
-(read/write) type. So for example, the read FIFO timeout values are
-tested only during read batches. Likewise, the write FIFO timeout
-values are tested only during write batches. For this reason,
-it is generally not recommended for the read batch time
-to be longer than the write expiration time, nor for the write batch
-time to exceed the read expiration time (see tunable parameters below).
-
-When the IO scheduler changes from a read to a write batch,
-it begins the elevator from the request that is on the head of the
-write expiration FIFO. Likewise, when changing from a write batch to
-a read batch, scheduler begins the elevator from the first entry
-on the read expiration FIFO.
-
-4. Read anticipation.
-
-Read anticipation occurs only when scheduling a read batch.
-This implementation of read anticipation allows only one read request
-to be dispatched to the disk controller at a time. In
-contrast, many write requests may be dispatched to the disk controller
-at a time during a write batch. It is this characteristic that can make
-the anticipatory scheduler perform anomalously with controllers supporting
-TCQ, or with hardware striped RAID devices. Setting the antic_expire
-queue paramter (see below) to zero disables this behavior, and the anticipatory
-scheduler behaves essentially like the deadline scheduler.
-
-When read anticipation is enabled (antic_expire is not zero), reads
-are dispatched to the disk controller one at a time.
-At the end of each read request, the IO scheduler examines its next
-candidate read request from its sorted read list. If that next request
-is from the same process as the request that just completed,
-or if the next request in the queue is "very close" to the
-just completed request, it is dispatched immediately. Otherwise,
-statistics (average think time, average seek distance) on the process
-that submitted the just completed request are examined. If it seems
-likely that that process will submit another request soon, and that
-request is likely to be near the just completed request, then the IO
-scheduler will stop dispatching more read requests for up time (antic_expire)
-milliseconds, hoping that process will submit a new request near the one
-that just completed. If such a request is made, then it is dispatched
-immediately. If the antic_expire wait time expires, then the IO scheduler
-will dispatch the next read request from the sorted read queue.
-
-To decide whether an anticipatory wait is worthwhile, the scheduler
-maintains statistics for each process that can be used to compute
-mean "think time" (the time between read requests), and mean seek
-distance for that process. One observation is that these statistics
-are associated with each process, but those statistics are not associated
-with a specific IO device. So for example, if a process is doing IO
-on several file systems on separate devices, the statistics will be
-a combination of IO behavior from all those devices.
-
-
-Tuning the anticipatory IO scheduler
-------------------------------------
-When using 'as', the anticipatory IO scheduler there are 5 parameters under
-/sys/block/*/iosched/. All are units of milliseconds.
-
-The parameters are:
-* read_expire
- Controls how long until a read request becomes "expired". It also controls the
- interval between which expired requests are served, so set to 50, a request
- might take anywhere < 100ms to be serviced _if_ it is the next on the
- expired list. Obviously request expiration strategies won't make the disk
- go faster. The result basically equates to the timeslice a single reader
- gets in the presence of other IO. 100*((seek time / read_expire) + 1) is
- very roughly the % streaming read efficiency your disk should get with
- multiple readers.
-
-* read_batch_expire
- Controls how much time a batch of reads is given before pending writes are
- served. A higher value is more efficient. This might be set below read_expire
- if writes are to be given higher priority than reads, but reads are to be
- as efficient as possible when there are no writes. Generally though, it
- should be some multiple of read_expire.
-
-* write_expire, and
-* write_batch_expire are equivalent to the above, for writes.
-
-* antic_expire
- Controls the maximum amount of time we can anticipate a good read (one
- with a short seek distance from the most recently completed request) before
- giving up. Many other factors may cause anticipation to be stopped early,
- or some processes will not be "anticipated" at all. Should be a bit higher
- for big seek time devices though not a linear correspondence - most
- processes have only a few ms thinktime.

-relayfs - a high-speed data relay filesystem
-============================================
-
-relayfs is a filesystem designed to provide an efficient mechanism for
-tools and facilities to relay large amounts of data from kernel space
-to user space.
-
-The main idea behind relayfs is that every data flow is put into a
-separate "channel" and each channel is a file. In practice, each
-channel is a separate memory buffer allocated from within kernel space
-upon channel instantiation. Software needing to relay data to user
-space would open a channel or a number of channels, depending on its
-needs, and would log data to that channel. All the buffering and
-locking mechanics are taken care of by relayfs. The actual format and
-protocol used for each channel is up to relayfs' clients.
-
-relayfs makes no provisions for copying the same data to more than a
-single channel. This is for the clients of the relay to take care of,
-and so is any form of data filtering. The purpose is to keep relayfs
-as simple as possible.
-
-
-Usage
-=====
-
-In addition to the relayfs kernel API described below, relayfs
-implements basic file operations. Here are the file operations that
-are available and some comments regarding their behavior:
-
-open() enables user to open an _existing_ channel. A channel can be
- opened in blocking or non-blocking mode, and can be opened
- for reading as well as for writing. Readers will by default
- be auto-consuming.
-
-mmap() results in channel's memory buffer being mmapped into the
- caller's memory space.
-
-read() since we are dealing with circular buffers, the user is only
- allowed to read forward. Some apps may want to loop around
- read() waiting for incoming data - if there is no data
- available, read will put the reader on a wait queue until
- data is available (blocking mode). Non-blocking reads return
- -EAGAIN if data is not available.
-
-
-write() writing from user space operates exactly as relay_write() does
- (described below).
-
-poll() POLLIN/POLLRDNORM/POLLOUT/POLLWRNORM/POLLERR supported.
-
-close() decrements the channel's refcount. When the refcount reaches
- 0 i.e. when no process or kernel client has the file open
- (see relay_close() below), the channel buffer is freed.
-
-
-In order for a user application to make use of relayfs files, the
-relayfs filesystem must be mounted. For example,
-
- mount -t relayfs relayfs /mountpoint
-
-
-The relayfs kernel API
-======================
-
-relayfs channels are implemented as circular buffers subdivided into
-'sub-buffers'. kernel clients write data into the channel using
-relay_write(), and are notified via a set of callbacks when
-significant events occur within the channel. 'Significant events'
-include:
-
-- a sub-buffer has been filled i.e. the current write won't fit into the
- current sub-buffer, and a 'buffer-switch' is triggered, after which
- the data is written into the next buffer (if the next buffer is
- empty). The client is notified of this condition via two callbacks,
- one providing an opportunity to perform start-of-buffer tasks, the
- other end-of-buffer tasks.
-
-- data is ready for the client to process. The client can choose to
- be notified either on a per-sub-buffer basis (bulk delivery) or
- per-write basis (packet delivery).
-
-- data has been written to the channel from user space. The client can
- use this notification to accept and process 'commands' sent to the
- channel via write(2).
-
-- the channel has been opened/closed/mapped/unmapped from user space.
- The client can use this notification to trigger actions within the
- kernel application, such as enabling/disabling logging to the
- channel. It can also return result codes from the callback,
- indicating that the operation should fail e.g. in order to restrict
- more than one user space open or mmap.
-
-- the channel needs resizing, or needs to update its
- state based on the results of the resize. Resizing the channel is
- up to the kernel client to actually perform. If the channel is
- configured for resizing, the client is notified when the unread data
- in the channel passes a preset threshold, giving it the opportunity
- to allocate a new channel buffer and replace the old one.
-
-Reader objects
---------------
-
-Channel readers use an opaque rchan_reader object to read from
-channels. For VFS readers (those using read(2) to read from a
-channel), these objects are automatically created and used internally;
-only kernel clients that need to directly read from channels, or whose
-userspace applications use mmap to access channel data, need to know
-anything about rchan_readers - others may skip this section.
-
-A relay channel can have any number of readers, each represented by an
-rchan_reader instance, which is used to encapsulate reader settings
-and state. rchan_reader objects should be treated as opaque by kernel
-clients. To create a reader object for directly accessing a channel
-from kernel space, call the add_rchan_reader() kernel API function:
-
-rchan_reader *add_rchan_reader(rchan_id, auto_consume)
-
-This function returns an rchan_reader instance if successful, which
-should then be passed to relay_read() when the kernel client is
-interested in reading from the channel.
-
-The auto_consume parameter indicates whether a read done by this
-reader will automatically 'consume' that portion of the unread channel
-buffer when relay_read() is called (see below for more details).
-
-To close the reader, call
-
-remove_rchan_reader(reader)
-
-which will remove the reader from the list of current readers.
-
-
-To create a reader object representing a userspace mmap reader in the
-kernel application, call the add_map_reader() kernel API function:
-
-rchan_reader *add_map_reader(rchan_id)
-
-This function returns an rchan_reader instance if successful, whose
-main purpose is as an argument to be passed into
-relay_buffers_consumed() when the kernel client becomes aware that
-data has been read by a user application using mmap to read from the
-channel buffer. There is no auto_consume option in this case, since
-only the kernel client/user application knows when data has been read.
-
-To close the map reader, call
-
-remove_map_reader(reader)
-
-which will remove the reader from the list of current readers.
-
-Consumed count
---------------
-
-A relayfs channel is a circular buffer, which means that if there is
-no reader reading from it or a reader reading too slowly, at some
-point the channel writer will 'lap' the reader and data will be lost.
-In normal use, readers will always be able to keep up with writers and
-the buffer is thus never in danger of becoming full. In many
-applications, it's sufficient to ensure that this is practically
-speaking always the case, by making the buffers large enough. These
-types of applications can basically open the channel as
-RELAY_MODE_CONTINOUS (the default anyway) and not worry about the
-meaning of 'consume' and skip the rest of this section.
-
-If it's important for the application that a kernel client never allow
-writers to overwrite unread data, the channel should be opened using
-RELAY_MODE_NO_OVERWRITE and must be kept apprised of the count of
-bytes actually read by the (typically) user-space channel readers.
-This count is referred to as the 'consumed count'. read(2) channel
-readers automatically update the channel's 'consumed count' as they
-read. If the usage mode is to have only read(2) readers, which is
-typically the case, the kernel client doesn't need to worry about any
-of the relayfs functions having to do with 'bytes consumed' and can
-skip the rest of this section. (Note that it is possible to have
-multiple read(2) or auto-consuming readers, but like having multiple
-readers on a pipe, these readers will race with each other i.e. it's
-supported, but doesn't make much sense).
-
-If the kernel client cannot rely on an auto-consuming reader to keep
-the 'consumed count' up-to-date, then it must do so manually, by
-making the appropriate calls to relay_buffers_consumed() or
-relay_bytes_consumed(). In most cases, this should only be necessary
-for bulk mmap clients - almost all packet clients should be covered by
-having auto-consuming read(2) readers. For mmapped bulk clients, for
-instance, there are no auto-consuming VFS readers, so the kernel
-client needs to make the call to relay_buffers_consumed() after
-sub-buffers are read.

-Here's a summary of the API relayfs provides to in-kernel clients:
-
-int relay_open(channel_path, bufsize, nbufs, channel_flags,

-----------
-int relay_open(channel_path, bufsize, nbufs,
- channel_flags, channel_callbacks, start_reserve,
- end_reserve, rchan_start_reserve, resize_min, resize_max, mode)
-
-relay_open() is used to create a new entry in relayfs. This new entry
-is created according to channel_path. channel_path contains the
-absolute path to the channel file on relayfs. If, for example, the
-caller sets channel_path to "/xlog/9", a "xlog/9" entry will appear
-within relayfs automatically and the "xlog" directory will be created
-in the filesystem's root. relayfs does not implement any policy on
-its content, except to disallow the opening of two channels using the
-same file. There are, nevertheless a set of guidelines for using
-relayfs. Basically, each facility using relayfs should use a top-level
-directory identifying it. The entry created above, for example,
-presumably belongs to the "xlog" software.
-
-The remaining parameters for relay_open() are as follows:
-
-- channel_flags - an ORed combination of attribute values controlling
- common channel characteristics:
-
- - logging scheme - relayfs use 2 mutually exclusive schemes
- for logging data to a channel. The 'lockless scheme'
- reserves and writes data to a channel without the need of
- any type of locking on the channel. This is the preferred
- scheme, but may not be available on a given architecture (it
- relies on the presence of a cmpxchg instruction). It's
- specified by the RELAY_SCHEME_LOCKLESS flag. The 'locking
- scheme' either obtains a lock on the channel for writing or
- disables interrupts, depending on whether the channel was
- opened for SMP or global usage (see below). It's specified
- by the RELAY_SCHEME_LOCKING flag. While a client may want
- to explicitly specify a particular scheme to use, it's more
- convenient to specify RELAY_SCHEME_ANY for this flag, which
- will allow relayfs to choose the best available scheme i.e.
- lockless if supported.
-
- - overwrite mode (default is RELAY_MODE_CONTINUOUS) -
- If RELAY_MODE_CONTINUOUS is specified, writes to the channel
- will succeed regardless of whether there are up-to-date
- consumers or not. If RELAY_MODE_NO_OVERWRITE is specified,
- the channel becomes 'full' when the total amount of buffer
- space unconsumed by readers equals or exceeds the total
- buffer size. With the buffer in this state, writes to the
- buffer will fail - clients need to check the return code from
- relay_write() to determine if this is the case and act
- accordingly - 0 or a negative value indicate the write failed.
-
- - SMP usage - this applies only when the locking scheme is in
- use. If RELAY_USAGE_SMP is specified, it's assumed that the
- channel will be used in a per-CPU fashion and consequently,
- the only locking that will be done for writes is to disable
- local irqs. If RELAY_USAGE_GLOBAL is specified, it's assumed
- that writes to the buffer can occur within any CPU context,
- and spinlock_irq_save will be used to lock the buffer.
-
- - delivery mode - if RELAY_DELIVERY_BULK is specified, the
- client will be notified via its deliver() callback whenever a
- sub-buffer has been filled. Alternatively,
- RELAY_DELIVERY_PACKET will cause delivery to occur after the
- completion of each write. See the description of the channel
- callbacks below for more details.
-
- - timestamping - if RELAY_TIMESTAMP_TSC is specified and the
- architecture supports it, efficient TSC 'timestamps' can be
- associated with each write, otherwise more expensive
- gettimeofday() timestamping is used. At the beginning of
- each sub-buffer, a gettimeofday() timestamp and the current
- TSC, if supported, are read, and are passed on to the client
- via the buffer_start() callback. This allows correlation of
- the current time with the current TSC for subsequent writes.
- Each subsequent write is associated with a 'time delta',
- which is either the current TSC, if the channel is using
- TSCs, or the difference between the buffer_start gettimeofday
- timestamp and the gettimeofday time read for the current
- write. Note that relayfs never writes either a timestamp or
- time delta into the buffer unless explicitly asked to (see
- the description of relay_write() for details).
-
-- bufsize - the size of the 'sub-buffers' making up the circular channel
- buffer. For the lockless scheme, this must be a power of 2.
-
-- nbufs - the number of 'sub-buffers' making up the circular
- channel buffer. This must be a power of 2.
-
- The total size of the channel buffer is bufsize * nbufs rounded up
- to the next kernel page size. If the lockless scheme is used, both
- bufsize and nbufs must be a power of 2. If the locking scheme is
- used, the bufsize can be anything and nbufs must be a power of 2. If
- RELAY_SCHEME_ANY is used, the bufsize and nbufs should be a power of 2.
-
- NOTE: if nbufs is 1, relayfs will bypass the normal size
- checks and will allocate an rvmalloced buffer of size bufsize.
- This buffer will be freed when relay_close() is called, if the channel
- isn't still being referenced.
-
-- callbacks - a table of callback functions called when events occur
- within the data relay that clients need to know about:
-
- - int buffer_start(channel_id, current_write_pos, buffer_id,
- start_time, start_tsc, using_tsc) -
-
- called at the beginning of a new sub-buffer, the
- buffer_start() callback gives the client an opportunity to
- write data into space reserved at the beginning of a
- sub-buffer. The client should only write into the buffer
- if it specified a value for start_reserve and/or
- channel_start_reserve (see below) when the channel was
- opened. In the latter case, the client can determine
- whether to write its one-time rchan_start_reserve data by
- examining the value of buffer_id, which will be 0 for the
- first sub-buffer. The address that the client can write
- to is contained in current_write_pos (the client by
- definition knows how much it can write i.e. the value it
- passed to relay_open() for start_reserve/
- channel_start_reserve). start_time contains the
- gettimeofday() value for the start of the buffer and start
- TSC contains the TSC read at the same time. The using_tsc
- param indicates whether or not start_tsc is valid (it
- wouldn't be if TSC timestamping isn't being used).
-
- The client should return the number of bytes it wrote to
- the channel, 0 if none.
-
- - int buffer_end(channel_id, current_write_pos, end_of_buffer,
- end_time, end_tsc, using_tsc)
-
- called at the end of a sub-buffer, the buffer_end()
- callback gives the client an opportunity to perform
- end-of-buffer processing. Note that the current_write_pos
- is the position where the next write would occur, but
- since the current write wouldn't fit (which is the trigger
- for the buffer_end event), the buffer is considered full
- even though there may be unused space at the end. The
- end_of_buffer param pointer value can be used to determine
- exactly the size of the unused space. The client should
- only write into the buffer if it specified a value for
- end_reserve when the channel was opened. If the client
- doesn't write anything i.e. returns 0, the unused space at
- the end of the sub-buffer is available via relay_info() -
- this data may be needed by the client later if it needs to
- process raw sub-buffers (an alternative would be to save
- the unused bytes count value in end_reserve space at the
- end of each sub-buffer during buffer_end processing and
- read it when needed at a later time. The other
- alternative would be to use read(2), which makes the
- unused count invisible to the caller). end_time contains
- the gettimeofday() value for the end of the buffer and end
- TSC contains the TSC read at the same time. The using_tsc
- param indicates whether or not end_tsc is valid (it
- wouldn't be if TSC timestamping isn't being used).
-
- The client should return the number of bytes it wrote to
- the channel, 0 if none.
-
- - void deliver(channel_id, from, len)
-
- called when data is ready for the client. This callback
- is used to notify a client when a sub-buffer is complete
- (in the case of bulk delivery) or a single write is
- complete (packet delivery). A bulk delivery client might
- wish to then signal a daemon that a sub-buffer is ready.
- A packet delivery client might wish to process the packet
- or send it elsewhere. The from param is a pointer to the
- delivered data and len specifies how many bytes are ready.
-
- - void user_deliver(channel_id, from, len)
-
- called when data has been written to the channel from user
- space. This callback is used to notify a client when a
- successful write from userspace has occurred, independent
- of whether bulk or packet delivery is in use. This can be
- used to allow userspace programs to communicate with the
- kernel client through the channel via out-of-band write(2)
- 'commands' instead of via ioctls, for instance. The from
- param is a pointer to the delivered data and len specifies
- how many bytes are ready. Note that this callback occurs
- after the bytes have been successfully written into the
- channel, which means that channel readers must be able to
- deal with the 'command' data which will appear in the
- channel data stream just as any other userspace or
- non-userspace write would.
-
- - int needs_resize(channel_id, resize_type,
- suggested_buf_size, suggested_n_bufs)
-
- called when a channel's buffers are in danger of becoming
- full i.e. the number of unread bytes in the channel passes
- a preset threshold, or when the current capacity of a
- channel's buffer is no longer needed. Also called to
- notify the client when a channel's buffer has been
- replaced. If resize_type is RELAY_RESIZE_EXPAND or
- RELAY_RESIZE_SHRINK, the kernel client should arrange to
- call relay_realloc_buffer() with the suggested buffer size
- and buffer count, which will allocate (but will not
- replace the old one) a new buffer of the recommended size
- for the channel. When the allocation has completed,
- needs_resize() is again called, this time with a
- resize_type of RELAY_RESIZE_REPLACE. The kernel client
- should then arrange to call relay_replace_buffer() to
- actually replace the old channel buffer with the newly
- allocated buffer. Finally, once the buffer replacement
- has completed, needs_resize() is again called, this time
- with a resize_type of RELAY_RESIZE_REPLACED, to inform the
- client that the replacement is complete and additionally
- confirming the current sub-buffer size and number of
- sub-buffers. Note that a resize can be canceled if
- relay_realloc_buffer() is called with the async param
- non-zero and the resize conditions no longer hold. In
- this case, the RELAY_RESIZE_REPLACED suggested number of
- sub-buffers will be the same as the number of sub-buffers
- that existed before the RELAY_RESIZE_SHRINK or EXPAND i.e.
- values indicating that the resize didn't actually occur.
-
- - int fileop_notify(channel_id, struct file *filp, enum relay_fileop)
-
- called when a userspace file operation has occurred or
- will occur on a relayfs channel file. These notifications
- can be used by the kernel client to trigger actions within
- the kernel client when the corresponding event occurs,
- such as enabling logging only when a userspace application
- opens or mmaps a relayfs file and disabling it again when
- the file is closed or unmapped. The kernel client can
- also return its own return value, which can affect the
- outcome of file operation - returning 0 indicates that the
- operation should succeed, and returning a negative value
- indicates that the operation should be failed, and that
- the returned value should be returned to the ultimate
- caller e.g. returning -EPERM from the open fileop will
- cause the open to fail with -EPERM. Among other things,
- the return value can be used to restrict a relayfs file
- from being opened or mmap'ed more than once. The currently
- implemented fileops are:
-
- RELAY_FILE_OPEN - a relayfs file is being opened. Return
- 0 to allow it to succeed, negative to
- have it fail. A negative return value will
- be passed on unmodified to the open fileop.
- RELAY_FILE_CLOSE- a relayfs file is being closed. The return
- value is ignored.
- RELAY_FILE_MAP - a relayfs file is being mmap'ed. Return 0
- to allow it to succeed, negative to have
- it fail. A negative return value will be
- passed on unmodified to the mmap fileop.
- RELAY_FILE_UNMAP- a relayfs file is being unmapped. The return
- value is ignored.
-
- - void ioctl(rchan_id, cmd, arg)
-
- called when an ioctl call is made using a relayfs file
- descriptor. The cmd and arg are passed along to this
- callback unmodified for it to do as it wishes with. The
- return value from this callback is used as the return value
- of the ioctl call.
-
- If the callbacks param passed to relay_open() is NULL, a set of
- default do-nothing callbacks will be defined for the channel.
- Likewise, any NULL rchan_callback function contained in a non-NULL
- callbacks struct will be filled in with a default callback function
- that does nothing.
-
-- start_reserve - the number of bytes to be reserved at the start of
- each sub-buffer. The client can do what it wants with this number
- of bytes when the buffer_start() callback is invoked. Typically
- clients would use this to write per-sub-buffer header data.
-
-- end_reserve - the number of bytes to be reserved at the end of each
- sub-buffer. The client can do what it wants with this number of
- bytes when the buffer_end() callback is invoked. Typically clients
- would use this to write per-sub-buffer footer data.
-
-- channel_start_reserve - the number of bytes to be reserved, in
- addition to start_reserve, at the beginning of the first sub-buffer
- in the channel. The client can do what it wants with this number of
- bytes when the buffer_start() callback is invoked. Typically
- clients would use this to write per-channel header data.
-
-- resize_min - if set, this signifies that the channel is
- auto-resizeable. The value specifies the size that the channel will
- try to maintain as a normal working size, and that it won't go
- below. The client makes use of the resizing callbacks and
- relay_realloc_buffer() and relay_replace_buffer() to actually effect
- the resize.
-
-- resize_max - if set, this signifies that the channel is
- auto-resizeable. The value specifies the maximum size the channel
- can have as a result of resizing.
-
-- mode - if non-zero, specifies the file permissions that will be given
- to the channel file. If 0, the default rw user perms will be used.
-
-- init_buf - if non-NULL, rather than allocating the channel buffer,
- this buffer will be used as the initial channel buffer. The kernel
- API function relay_discard_init_buf() can later be used to have
- relayfs allocate a normal mmappable channel buffer and switch over
- to using it after copying the init_buf contents into it. Currently,
- the size of init_buf must be exactly buf_size * n_bufs. The caller
- is responsible for managing the init_buf memory. This feature is
- typically used for init-time channel use and should normally be
- specified as NULL.
-
-- init_buf_size - the total size of init_buf, if init_buf is specified
- as non-NULL. Currently, the size of init_buf must be exactly
- buf_size * n_bufs.
-
-Upon successful completion, relay_open() returns a channel id
-to be used for all other operations with the relay. All buffers
-managed by the relay are allocated using rvmalloc/rvfree to allow
-for easy mmapping to user-space.
-
-----------
-int relay_write(channel_id, *data_ptr, count, time_delta_offset, **wrote_pos)
-
-relay_write() reserves space in the channel and writes count bytes of
-data pointed to by data_ptr to it. Automatically performs any
-necessary locking, depending on the scheme and SMP usage in effect (no
-locking is done for the lockless scheme regardless of usage). It
-returns the number of bytes written, or 0/negative on failure. If
-time_delta_offset is >= 0, the internal time delta, the internal time
-delta calculated when the slot was reserved will be written at that
-offset. This is the TSC or gettimeofday() delta between the current
-write and the beginning of the buffer, whichever method is being used
-by the channel. Trying to write a count larger than the bufsize
-specified to relay_open() (taking into account the reserved
-start-of-buffer and end-of-buffer space as well) will fail. If
-wrote_pos is non-NULL, it will receive the location the data was
-written to, which may be needed for some applications but is not
-normally interesting. Most applications should pass in NULL for this
-param.
-
-----------
-struct rchan_reader *add_rchan_reader(int rchan_id, int auto_consume)
-
-add_rchan_reader creates and initializes a reader object for a
-channel. An opaque rchan_reader object is returned on success, and is
-passed to relay_read() when reading the channel. If the boolean
-auto_consume parameter is 1, the reader is defined to be
-auto-consuming. auto-consuming reader objects are automatically
-created and used for VFS read(2) readers.
-
-----------
-void remove_rchan_reader(struct rchan_reader *reader)
-
-remove_rchan_reader finds and removes the given reader from the
-channel. This function is used only by non-VFS read(2) readers. VFS
-read(2) readers are automatically removed when the corresponding file
-object is closed.
-
-----------
-reader add_map_reader(int rchan_id)
-
-Creates and initializes an rchan_reader object for channel map
-readers, and is needed for updating relay_bytes/buffers_consumed()
-when kernel clients become aware of the need to do so by their mmap
-user clients.
-
-----------
-int remove_map_reader(reader)
-
-Finds and removes the given map reader from the channel. This function
-is useful only for map readers.
-
-----------
-int relay_read(reader, buf, count, wait, *actual_read_offset)
-
-Reads count bytes from the channel, or as much as is available within
-the sub-buffer currently being read. The read offset that will be
-read from is the position contained within the reader object. If the
-wait flag is set, buf is non-NULL, and there is nothing available, it
-will wait until there is. If the wait flag is 0 and there is nothing
-available, -EAGAIN is returned. If buf is NULL, the value returned is
-the number of bytes that would have been read. actual_read_offset is
-the value that should be passed as the read offset to
-relay_bytes_consumed, needed only if the reader is not auto-consuming
-and the channel is MODE_NO_OVERWRITE, but in any case, it must not be
-NULL.
-
-----------
-
-int relay_bytes_avail(reader)
-
-Returns the number of bytes available relative to the reader's current
-read position within the corresponding sub-buffer, 0 if there is
-nothing available. Note that this doesn't return the total bytes
-available in the channel buffer - this is enough though to know if
-anything is available, however, or how many bytes might be returned
-from the next read.
-
-----------
-void relay_buffers_consumed(reader, buffers_consumed)
-
-Adds to the channel's consumed buffer count. buffers_consumed should
-be the number of buffers newly consumed, not the total number
-consumed. NOTE: kernel clients don't need to call this function if
-the reader is auto-consuming or the channel is MODE_CONTINUOUS.
-
-In order for the relay to detect the 'buffers full' condition for a
-channel, it must be kept up-to-date with respect to the number of
-buffers consumed by the client. If the addition of the value of the
-bufs_consumed param to the current bufs_consumed count for the channel
-would exceed the bufs_produced count for the channel, the channel's
-bufs_consumed count will be set to the bufs_produced count for the
-channel. This allows clients to 'catch up' if necessary.
-
-----------
-void relay_bytes_consumed(reader, bytes_consumed, read_offset)
-
-Adds to the channel's consumed count. bytes_consumed should be the
-number of bytes actually read e.g. return value of relay_read() and
-the read_offset should be the actual offset the bytes were read from
-e.g. the actual_read_offset set by relay_read(). NOTE: kernel clients
-don't need to call this function if the reader is auto-consuming or
-the channel is MODE_CONTINUOUS.
-
-In order for the relay to detect the 'buffers full' condition for a
-channel, it must be kept up-to-date with respect to the number of
-bytes consumed by the client. For packet clients, it makes more sense
-to update after each read rather than after each complete sub-buffer
-read. The bytes_consumed count updates bufs_consumed when a buffer
-has been consumed so this count remains consistent.
-
-----------
-int relay_info(channel_id, *channel_info)
-
-relay_info() fills in an rchan_info struct with channel status and
-attribute information such as usage modes, sub-buffer size and count,
-the allocated size of the entire buffer, buffers produced and
-consumed, current buffer id, count of writes lost due to buffers full
-condition.
-
-The virtual address of the channel buffer is also available here, for
-those clients that need it.
-
-Clients may need to know how many 'unused' bytes there are at the end
-of a given sub-buffer. This would only be the case if the client 1)
-didn't either write this count to the end of the sub-buffer or
-otherwise note it (it's available as the difference between the buffer
-end and current write pos params in the buffer_end callback) (if the
-client returned 0 from the buffer_end callback, it's assumed that this
-is indeed the case) 2) isn't using the read() system call to read the
-buffer. In other words, if the client isn't annotating the stream and
-is reading the buffer by mmaping it, this information would be needed
-in order for the client to 'skip over' the unused bytes at the ends of
-sub-buffers.
-
-Additionally, for the lockless scheme, clients may need to know
-whether a particular sub-buffer is actually complete. An array of
-boolean values, one per sub-buffer, contains non-zero if the buffer is
-complete, non-zero otherwise.
-
-----------
-int relay_close(channel_id)
-
-relay_close() is used to close the channel. It finalizes the last
-sub-buffer (the one currently being written to) and marks the channel
-as finalized. The channel buffer and channel data structure are then
-freed automatically when the last reference to the channel is given
-up.
-
-----------
-int relay_realloc_buffer(channel_id, nbufs, async)
-
-Allocates a new channel buffer using the specified sub-buffer count
-(note that resizing can't change sub-buffer sizes). If async is
-non-zero, the allocation is done in the background using a work queue.
-When the allocation has completed, the needs_resize() callback is
-called with a resize_type of RELAY_RESIZE_REPLACE. This function
-doesn't replace the old buffer with the new - see
-relay_replace_buffer().
-
-This function is called by kernel clients in response to a
-needs_resize() callback call with a resize type of RELAY_RESIZE_EXPAND
-or RELAY_RESIZE_SHRINK. That callback also includes a suggested
-new_bufsize and new_nbufs which should be used when calling this
-function.
-
-Returns 0 on success, or errcode if the channel is busy or if
-the allocation couldn't happen for some reason.
-
-NOTE: if async is not set, this function should not be called with a
-lock held, as it may sleep.
-
-----------
-int relay_replace_buffer(channel_id)
-
-Replaces the current channel buffer with the new buffer allocated by
-relay_realloc_buffer and contained in the channel struct. When the
-replacement is complete, the needs_resize() callback is called with
-RELAY_RESIZE_REPLACED. This function is called by kernel clients in
-response to a needs_resize() callback having a resize type of
-RELAY_RESIZE_REPLACE.
-
-Returns 0 on success, or errcode if the channel is busy or if the
-replacement or previous allocation didn't happen for some reason.
-
-NOTE: This function will not sleep, so can called in any context and
-with locks held. The client should, however, ensure that the channel
-isn't actively being read from or written to.
-
-----------
-int relay_reset(rchan_id)
-
-relay_reset() has the effect of erasing all data from the buffer and
-restarting the channel in its initial state. The buffer itself is not
-freed, so any mappings are still in effect. NOTE: Care should be
-taken that the channnel isn't actually being used by anything when
-this call is made.
-
-----------
-int rchan_full(reader)
-
-returns 1 if the channel is full with respect to the reader, 0 if not.
-
-----------
-int rchan_empty(reader)
-
-returns 1 if the channel is empty with respect to the reader, 0 if not.
-
-----------
-int relay_discard_init_buf(rchan_id)
-
-allocates an mmappable channel buffer, copies the contents of init_buf
-into it, and sets the current channel buffer to the newly allocated
-buffer. This function is used only in conjunction with the init_buf
-and init_buf_size params to relay_open(), and is typically used when
-the ability to write into the channel at init-time is needed. The
-basic usage is to specify an init_buf and init_buf_size to relay_open,
-then call this function when it's safe to switch over to a normally
-allocated channel buffer. 'Safe' means that the caller is in a
-context that can sleep and that nothing is actively writing to the
-channel. Returns 0 if successful, negative otherwise.
-
-
-Writing directly into the channel
-=================================
-
-Using the relay_write() API function as described above is the
-preferred means of writing into a channel. In some cases, however,
-in-kernel clients might want to write directly into a relay channel
-rather than have relay_write() copy it into the buffer on the client's
-behalf. Clients wishing to do this should follow the model used to
-implement relay_write itself. The general sequence is:
-
-- get a pointer to the channel via rchan_get(). This increments the
- channel's reference count.
-- call relay_lock_channel(). This will perform the proper locking for
- the channel given the scheme in use and the SMP usage.
-- reserve a slot in the channel via relay_reserve()
-- write directly to the reserved address
-- call relay_commit() to commit the write
-- call relay_unlock_channel()
-- call rchan_put() to release the channel reference
-
-In particular, clients should make sure they call rchan_get() and
-rchan_put() and not hold on to references to the channel pointer.
-Also, forgetting to use relay_lock_channel()/relay_unlock_channel()
-has no effect if the lockless scheme is being used, but could result
-in corrupted buffer contents if the locking scheme is used.
-
-
-Limitations
-===========
-
-Writes made via the write() system call are currently limited to 2
-pages worth of data. There is no such limit on the in-kernel API
-function relay_write().
-
-User applications can currently only mmap the complete buffer (it
-doesn't really make sense to mmap only part of it, given its purpose).
-
-
-Latest version

-The latest version can be found at:
-
-http://www.opersys.com/relayfs
-
-Example relayfs clients, such as dynamic printk and the Linux Trace
-Toolkit, can also be found there.

-Primitive parallel port is driver for i2c bus, which exploits
-features of modern bidirectional parallel ports.
-
-Bidirectional ports have particular bits connected in following way:
-
- |
- /-----| R
- --o| |-----|
- read \-----| /------- Out pin
- |/
- - -|\
- write V
- |
- ---
-
-
-It means when output is set to 1 we can read the port. Therefore
-we can use 2 pins of parallel port as SDA and SCL for i2c bus. It
-is not necessary to add any external - additional parts, we can
-read and write the same port simultaneously.
- I only use register base+2 so it is possible to use all
-8 data bits of parallel port for other applications (I have
-connected EEPROM and LCD display). I do not use bit Enable Bi-directional
- Port. The only disadvantage is we can only support 5V chips.
-
-Layout:
-
-Cannon 25 pin
-
-SDA - connect to pin 14 (Auto Linefeed)
-SCL - connect to pin 16 (Initialize Printer)
-GND - connect to pin 18-25
-+5V - use external supply (I use 5V from 3.5" floppy connector)
-
-no pullups requied
-
-Module parameters:
-
-base = 0xXXX
-XXX - 278 or 378
-
-That's all.

-Linux I2O User Space Interface
-rev 0.3 - 04/20/99
-
-=============================================================================
-Originally written by Deepak Saxena(deepak@plexity.net)
-Currently maintained by Deepak Saxena(deepak@plexity.net)
-=============================================================================
-
-I. Introduction
-
-The Linux I2O subsystem provides a set of ioctl() commands that can be
-utilized by user space applications to communicate with IOPs and devices
-on individual IOPs. This document defines the specific ioctl() commands
-that are available to the user and provides examples of their uses.
-
-This document assumes the reader is familiar with or has access to the
-I2O specification as no I2O message parameters are outlined. For information
-on the specification, see http://www.i2osig.org
-
-This document and the I2O user space interface are currently maintained
-by Deepak Saxena. Please send all comments, errata, and bug fixes to
-deepak@csociety.purdue.edu
-
-II. IOP Access
-
-Access to the I2O subsystem is provided through the device file named
-/dev/i2o/ctl. This file is a character file with major number 10 and minor
-number 166. It can be created through the following command:
-
- mknod /dev/i2o/ctl c 10 166
-
-III. Determining the IOP Count
-

-
- ioctl(fd, I2OGETIOPS, int *count);
-
- u8 count[MAX_I2O_CONTROLLERS];
-
- DESCRIPTION
-
- This function returns the system's active IOP table. count should
- point to a buffer containing MAX_I2O_CONTROLLERS entries. Upon
- returning, each entry will contain a non-zero value if the given
- IOP unit is active, and NULL if it is inactive or non-existent.
-
- RETURN VALUE.
-
- Returns 0 if no errors occur, and -1 otherwise. If an error occurs,
- errno is set appropriately:
-
- EFAULT Invalid user space pointer was passed
-
-IV. Getting Hardware Resource Table
-
- SYNOPSIS
-
- ioctl(fd, I2OHRTGET, struct i2o_cmd_hrt *hrt);

- by htquery->iop and htquery->tid. The requested HTML page number is
- provided by the htquery->page field, and the resultant data is stored
- in the buffer pointed to by htquery->resbuf. If there is an HTTP query
- string that is to be sent to the device, it should be sent in the buffer
- pointed to by htquery->qbuf. If there is no query string, this field
- should be set to NULL. The actual size of the reply received is written
- into *(htquery->reslen).
-
- RETURNS
-
- This function returns 0 if no error occur. If an error occurs, -1
- is returned and errno is set appropriatly:
-
- EFAULT Invalid user space pointer was passed

- buffer length is written into *(ops->reslen)
- ETIMEDOUT Timeout waiting for reply message
- ENOMEM Kernel memory allocation error
-
-XII. Events
-
- In the process of determining this. Current idea is to have use
- the select() interface to allow user apps to periodically poll
- the /dev/i2o/ctl device for events. When select() notifies the user
- that an event is available, the user would call read() to retrieve
- a list of all the events that are pending for the specific device.

-Generic networking statistics for netlink users
-======================================================================
-
-Statistic counters are grouped into structs:
-
-Struct TLV type Description
-----------------------------------------------------------------------
-gnet_stats_basic TCA_STATS_BASIC Basic statistics
-gnet_stats_rate_est TCA_STATS_RATE_EST Rate estimator
-gnet_stats_queue TCA_STATS_QUEUE Queue statistics
-none TCA_STATS_APP Application specific
-
-
-Collecting:
------------
-
-Declare the statistic structs you need:
-struct mystruct {
- struct gnet_stats_basic bstats;
- struct gnet_stats_queue qstats;
- ...
-};
-
-Update statistics:
-mystruct->tstats.packet++;
-mystruct->qstats.backlog += skb->pkt_len;
-
-
-Export to userspace (Dump):
----------------------------
-
-my_dumping_routine(struct sk_buff *skb, ...)
-{
- struct gnet_dump dump;
-
- if (gnet_stats_start_copy(skb, TCA_STATS2, &mystruct->lock, &dump) < 0)
- goto rtattr_failure;
-
- if (gnet_stats_copy_basic(&dump, &mystruct->bstats) < 0 ||
- gnet_stats_copy_queue(&dump, &mystruct->qstats) < 0 ||
- gnet_stats_copy_app(&dump, &xstats, sizeof(xstats)) < 0)
- goto rtattr_failure;
-
- if (gnet_stats_finish_copy(&dump) < 0)
- goto rtattr_failure;
- ...
-}
-
-TCA_STATS/TCA_XSTATS backward compatibility:
---------------------------------------------
-
-Prior users of struct tc_stats and xstats can maintain backward
-compatibility by calling the compat wrappers to keep providing the
-existing TLV types.
-
-my_dumping_routine(struct sk_buff *skb, ...)
-{
- if (gnet_stats_start_copy_compat(skb, TCA_STATS2, TCA_STATS,
- TCA_XSTATS, &mystruct->lock, &dump) < 0)
- goto rtattr_failure;
- ...
-}
-
-A struct tc_stats will be filled out during gnet_stats_copy_* calls
-and appended to the skb. TCA_XSTATS is provided if gnet_stats_copy_app
-was called.
-
-
-Locking:
---------
-
-Locks are taken before writing and released once all statistics have
-been written. Locks are always released in case of an error. You
-are responsible for making sure that the lock is initialized.
-
-
-Rate Estimator:
---------------
-
-0) Prepare an estimator attribute. Most likely this would be in user
- space. The value of this TLV should contain a tc_estimator structure.
- As usual, such a TLV nees to be 32 bit aligned and therefore the
- length needs to be appropriately set etc. The estimator interval
- and ewma log need to be converted to the appropriate values.
- tc_estimator.c::tc_setup_estimator() is advisable to be used as the
- conversion routine. It does a few clever things. It takes a time
- interval in microsecs, a time constant also in microsecs and a struct
- tc_estimator to be populated. The returned tc_estimator can be
- transported to the kernel. Transfer such a structure in a TLV of type
- TCA_RATE to your code in the kernel.
-
-In the kernel when setting up:
-1) make sure you have basic stats and rate stats setup first.
-2) make sure you have initialized stats lock that is used to setup such
- stats.
-3) Now initialize a new estimator:
-
- int ret = gen_new_estimator(my_basicstats,my_rate_est_stats,
- mystats_lock, attr_with_tcestimator_struct);
-
- if ret == 0
- success
- else
- failed
-
-From now on, everytime you dump my_rate_est_stats it will contain
-uptodate info.
-
-Once you are done, call gen_kill_estimator(my_basicstats,
-my_rate_est_stats) Make sure that my_basicstats and my_rate_est_stats
-are still valid (i.e still exist) at the time of making this call.

-Version 10 of schedstats includes support for sched_domains, which
-hit the mainline kernel in 2.6.7. Some counters make more sense to be
-per-runqueue; other to be per-domain. Note that domains (and their associated
-information) will only be pertinent and available on machines utilizing
-CONFIG_SMP.
-
-In version 10 of schedstat, there is at least one level of domain
-statistics for each cpu listed, and there may well be more than one
-domain. Domains have no particular names in this implementation, but
-the highest numbered one typically arbitrates balancing across all the
-cpus on the machine, while domain0 is the most tightly focused domain,
-sometimes balancing only between pairs of cpus. At this time, there
-are no architectures which need more than three domain levels. The first
-field in the domain stats is a bit map indicating which cpus are affected
-by that domain.
-
-These fields are counters, and only increment. Programs which make use
-of these will need to start with a baseline observation and then calculate
-the change in the counters at each subsequent observation. A perl script
-which does this for many of the fields is available at
-
- http://eaglet.rain.com/rick/linux/schedstat/
-
-Note that any such script will necessarily be version-specific, as the main
-reason to change versions is changes in the output format. For those wishing
-to write their own scripts, the fields are described here.
-
-CPU statistics
---------------
-cpu<N> 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28
-
-NOTE: In the sched_yield() statistics, the active queue is considered empty
- if it has only one process in it, since obviously the process calling
- sched_yield() is that process.
-
-First four fields are sched_yield() statistics:
- 1) # of times both the active and the expired queue were empty
- 2) # of times just the active queue was empty
- 3) # of times just the expired queue was empty
- 4) # of times sched_yield() was called
-
-Next four are schedule() statistics:
- 5) # of times the active queue had at least one other process on it
- 6) # of times we switched to the expired queue and reused it
- 7) # of times schedule() was called
- 8) # of times schedule() left the processor idle
-
-Next four are active_load_balance() statistics:
- 9) # of times active_load_balance() was called
- 10) # of times active_load_balance() caused this cpu to gain a task
- 11) # of times active_load_balance() caused this cpu to lose a task
- 12) # of times active_load_balance() tried to move a task and failed
-
-Next three are try_to_wake_up() statistics:
- 13) # of times try_to_wake_up() was called
- 14) # of times try_to_wake_up() successfully moved the awakening task
- 15) # of times try_to_wake_up() attempted to move the awakening task
-
-Next two are wake_up_new_task() statistics:
- 16) # of times wake_up_new_task() was called
- 17) # of times wake_up_new_task() successfully moved the new task
-
-Next one is a sched_migrate_task() statistic:
- 18) # of times sched_migrate_task() was called
-
-Next one is a sched_balance_exec() statistic:
- 19) # of times sched_balance_exec() was called
-
-Next three are statistics describing scheduling latency:
- 20) sum of all time spent running by tasks on this processor (in ms)
- 21) sum of all time spent waiting to run by tasks on this processor (in ms)
- 22) # of tasks (not necessarily unique) given to the processor
-
-The last six are statistics dealing with pull_task():
- 23) # of times pull_task() moved a task to this cpu when newly idle
- 24) # of times pull_task() stole a task from this cpu when another cpu

-Domain statistics
------------------
-One of these is produced per domain for each cpu described. (Note that if
-CONFIG_SMP is not defined, *no* domains are utilized and these lines
-will not appear in the output.)
-
-domain<N> 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
-
-The first field is a bit mask indicating what cpus this domain operates over.
-
-The next fifteen are a variety of load_balance() statistics:
-
- 1) # of times in this domain load_balance() was called when the cpu
- was idle
- 2) # of times in this domain load_balance() was called when the cpu
- was busy
- 3) # of times in this domain load_balance() was called when the cpu
- was just becoming idle
- 4) # of times in this domain load_balance() tried to move one or more
- tasks and failed, when the cpu was idle
- 5) # of times in this domain load_balance() tried to move one or more
- tasks and failed, when the cpu was busy
- 6) # of times in this domain load_balance() tried to move one or more
- tasks and failed, when the cpu was just becoming idle
- 7) sum of imbalances discovered (if any) with each call to
- load_balance() in this domain when the cpu was idle
- 8) sum of imbalances discovered (if any) with each call to
- load_balance() in this domain when the cpu was busy
- 9) sum of imbalances discovered (if any) with each call to
- load_balance() in this domain when the cpu was just becoming idle
- 10) # of times in this domain load_balance() was called but did not find
- a busier queue while the cpu was idle
- 11) # of times in this domain load_balance() was called but did not find
- a busier queue while the cpu was busy
- 12) # of times in this domain load_balance() was called but did not find
- a busier queue while the cpu was just becoming idle
- 13) # of times in this domain a busier queue was found while the cpu was
- idle but no busier group was found
- 14) # of times in this domain a busier queue was found while the cpu was
- busy but no busier group was found
- 15) # of times in this domain a busier queue was found while the cpu was
- just becoming idle but no busier group was found
-
-Next two are sched_balance_exec() statistics:
- 17) # of times in this domain sched_balance_exec() successfully pushed
- a task to a new cpu
- 18) # of times in this domain sched_balance_exec() tried but failed to
- push a task to a new cpu
-
-Next two are try_to_wake_up() statistics:
- 19) # of times in this domain try_to_wake_up() tried to move a task based
- on affinity and cache warmth
- 20) # of times in this domain try_to_wake_up() tried to move a task based
- on load balancing
-
-
-/proc/<pid>/schedstat
-----------------
-schedstats also adds a new /proc/<pid/schedstat file to include some of
-the same information on a per-process level. There are three fields in
-this file correlating to fields 20, 21, and 22 in the CPU fields, but
-they only apply for that process.
-
-A program could be easily written to make use of these extra fields to
-report on how well a particular process or set of processes is faring
-under the scheduler's policies. A simple version of such a program is
-available at
- http://eaglet.rain.com/rick/linux/schedstat/v10/latency.c

- Notes on Management Module
- ~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Overview:
---------
-
-Different classes of controllers from LSI Logic, accept and respond to the
-user applications in a similar way. They understand the same firmware control
-commands. Furthermore, the applications also can treat different classes of
-the controllers uniformly. Hence it is logical to have a single module that
-interefaces with the applications on one side and all the low level drivers
-on the other.
-
-The advantages, though obvious, are listed for completeness:
-
- i. Avoid duplicate code from the low level drivers.
- ii. Unburden the low level drivers from having to export the
- character node device and related handling.
- iii. Implement any policy mechanisms in one place.
- iv. Applications have to interface with only module instead of
- multiple low level drivers.
-
-Currently this module (called Common Management Module) is used only to issue
-ioctl commands. But this module is envisioned to handle all user space level
-interactions. So any 'proc', 'sysfs' implementations will be localized in this
-common module.
-
-Credits:
--------
-
-"Shared code in a third module, a "library module", is an acceptable
-solution. modprobe automatically loads dependent modules, so users
-running "modprobe driver1" or "modprobe driver2" would automatically
-load the shared library module."
-
- - Jeff Garzik (jgarzik@pobox.com), 02.25.2004 LKML
-
-"As Jeff hinted, if your userspace<->driver API is consistent between
-your new MPT-based RAID controllers and your existing megaraid driver,
-then perhaps you need a single small helper module (lsiioctl or some
-better name), loaded by both mptraid and megaraid automatically, which
-handles registering the /dev/megaraid node dynamically. In this case,
-both mptraid and megaraid would register with lsiioctl for each
-adapter discovered, and lsiioctl would essentially be a switch,
-redirecting userspace tool ioctls to the appropriate driver."
-
- - Matt Domsch, (Matt_Domsch@dell.com), 02.25.2004 LKML
-
-Design:
-------
-
-The Common Management Module is implemented in megaraid_mm.[ch] files. This
-module acts as a registry for low level hba drivers. The low level drivers
-(currently only megaraid) register each controller with the common module.
-
-The applications interface with the common module via the character device
-node exported by the module.
-
-The lower level drivers now understand only a new improved ioctl packet called
-uioc_t. The management module converts the older ioctl packets from the older
-applications into uioc_t. After driver handles the uioc_t, the common module
-will convert that back into the old format before returning to applications.
-
-As new applications evolve and replace the old ones, the old packet format
-will be retired.
-
-Common module dedicates one uioc_t packet to each controller registered. This
-can easily be more than one. But since megaraid is the only low level driver
-today, and it can handle only one ioctl, there is no reason to have more. But
-as new controller classes get added, this will be tuned appropriately.

-Time Interpolators
-------------------
-
-Time interpolators are a base of time calculation between timer ticks and
-allow an accurate determination of time down to the accuracy of the time
-source in nanoseconds.
-
-The architecture specific code typically provides gettimeofday and
-settimeofday under Linux. The time interpolator provides both if an arch
-defines CONFIG_TIME_INTERPOLATION. The arch still must set up timer tick
-operations and call the necessary functions to advance the clock.
-With the time interpolator a standardized interface exists for time
-interpolation between ticks which also allows the determination
-of time in a hardware independent way. The provided logic is highly scalable
-and has been tested in SMP situations of up to 512 CPUs.
-
-If CONFIG_TIME_INTERPOLATION is defined then the architecture specific code
-(or the device drivers - like HPET) must register time interpolators.
-These are typically defined in the following way:
-
-static struct time_interpolator my_interpolator;
-
-void time_init(void)
-{
- ....
- /* Initialization of the timer *.
- my_interpolator.frequency = MY_FREQUENCY;
- my_interpolator.source = TIME_SOURCE_MMIO32;
- my_interpolator.address = &my_timer;
- my_interpolator.shift = 32; /* increase accuracy of scaling */
- my_interpolator.drift = -1; /* Unknown */
- my_interpolator.jitter = 0; /* A stable time source */
- register_time_interpolator(&my_interpolator);
- ....
-}

- The Lockronomicon
-
-Your guide to the ancient and twisted locking policies of the tty layer and
-the warped logic behind them. Beware all ye who read on.
-
-FIXME: still need to work out the full set of BKL assumptions and document
-them so they can eventually be killed off.
-
-
-Line Discipline
----------------
-
-Line disciplines are registered with tty_register_ldisc() passing the
-discipline number and the ldisc structure. At the point of registration the
-discipline must be ready to use and it is possible it will get used before
-the call returns success. If the call returns an error then it won't get
-called. Do not re-use ldisc numbers as they are part of the userspace ABI
-and writing over an existing ldisc will cause demons to eat your computer.
-After the return the ldisc data has been copied so you may free your own
-copy of the structure. You must not re-register over the top of the line
-discipline even with the same data or your computer again will be eaten by
-demons.
-
-In order to remove a line discipline call tty_register_ldisc passing NULL.
-In ancient times this always worked. In modern times the function will
-return -EBUSY if the ldisc is currently in use. Since the ldisc referencing
-code manages the module counts this should not usually be a concern.
-
-Heed this warning: the reference count field of the registered copies of the
-tty_ldisc structure in the ldisc table counts the number of lines using this
-discipline. The reference count of the tty_ldisc structure within a tty
-counts the number of active users of the ldisc at this instant. In effect it
-counts the number of threads of execution within an ldisc method (plus those
-about to enter and exit although this detail matters not).
-
-Line Discipline Methods
------------------------
-
-TTY side interfaces:
-
-close() - This is called on a terminal when the line
- discipline is being unplugged. At the point of
- execution no further users will enter the
- ldisc code for this tty. Can sleep.
-
-open() - Called when the line discipline is attached to
- the terminal. No other call into the line
- discipline for this tty will occur until it
- completes successfully. Can sleep.
-
-write() - A process is writing data from user space
- through the line discipline. Multiple write calls
- are serialized by the tty layer for the ldisc. May
- sleep.
-
-flush_buffer() - May be called at any point between open and close.
-
-chars_in_buffer() - Report the number of bytes in the buffer.
-
-set_termios() - Called on termios structure changes. The caller
- passes the old termios data and the current data
- is in the tty. Called under the termios semaphore so
- allowed to sleep. Serialized against itself only.
-
-read() - Move data from the line discipline to the user.
- Multiple read calls may occur in parallel and the
- ldisc must deal with serialization issues. May
- sleep.
-
-poll() - Check the status for the poll/select calls. Multiple
- poll calls may occur in parallel. May sleep.
-
-ioctl() - Called when an ioctl is handed to the tty layer
- that might be for the ldisc. Multiple ioctl calls
- may occur in parallel. May sleep.
-
-Driver Side Interfaces:
-
-receive_buf() - Hand buffers of bytes from the driver to the ldisc
- for processing. Semantics currently rather
- mysterious 8(
-
-receive_room() - Can be called by the driver layer at any time when
- the ldisc is opened. The ldisc must be able to
- handle the reported amount of data at that instant.
- Synchronization between active receive_buf and
- receive_room calls is down to the driver not the
- ldisc. Must not sleep.
-
-write_wakeup() - May be called at any point between open and close.
- The TTY_DO_WRITE_WAKEUP flag indicates if a call
- is needed but always races versus calls. Thus the
- ldisc must be careful about setting order and to
- handle unexpected calls. Must not sleep.
-
-
-Locking
-
-Callers to the line discipline functions from the tty layer are required to
-take line discipline locks. The same is true of calls from the driver side
-but not yet enforced.
-
-Three calls are now provided
-
- ldisc = tty_ldisc_ref(tty);
-
-takes a handle to the line discipline in the tty and returns it. If no ldisc
-is currently attached or the ldisc is being closed and re-opened at this
-point then NULL is returned. While this handle is held the ldisc will not
-change or go away.
-
- tty_ldisc_deref(ldisc)
-
-Returns the ldisc reference and allows the ldisc to be closed. Returning the
-reference takes away your right to call the ldisc functions until you take
-a new reference.
-
- ldisc = tty_ldisc_ref_wait(tty);
-
-Performs the same function as tty_ldisc_ref except that it will wait for an
-ldisc change to complete and then return a reference to the new ldisc.
-
-While these functions are slightly slower than the old code they should have
-minimal impact as most receive logic uses the flip buffers and they only
-need to take a reference when they push bits up through the driver.
-
-A caution: The ldisc->open(), ldisc->close() and driver->set_ldisc
-functions are called with the ldisc unavailable. Thus tty_ldisc_ref will
-fail in this situation if used within these functions. Ldisc and driver
-code calling its own functions must be careful in this case.
-
-
-Driver Interface
-----------------
-
-open() - Called when a device is opened. May sleep
-
-close() - Called when a device is closed. At the point of
- return from this call the driver must make no
- further ldisc calls of any kind. May sleep
-
-write() - Called to write bytes to the device. May not
- sleep. May occur in parallel in special cases.
- Because this includes panic paths drivers generally
- shouldn't try and do clever locking here.
-
-put_char() - Stuff a single character onto the queue. The
- driver is guaranteed following up calls to
- flush_chars.
-
-flush_chars() - Ask the kernel to write put_char queue
-
-write_room() - Return the number of characters tht can be stuffed
- into the port buffers without overflow (or less).
- The ldisc is responsible for being intelligent
- about multi-threading of write_room/write calls
-
-ioctl() - Called when an ioctl may be for the driver
-
-set_termios() - Called on termios change, serialized against
- itself by a semaphore. May sleep.
-
-set_ldisc() - Notifier for discipline change. At the point this
- is done the discipline is not yet usable. Can now
- sleep (I think)
-
-throttle() - Called by the ldisc to ask the driver to do flow
- control. Serialization including with unthrottle
- is the job of the ldisc layer.
-
-unthrottle() - Called by the ldisc to ask the driver to stop flow
- control.
-
-stop() - Ldisc notifier to the driver to stop output. As with
- throttle the serializations with start() are down
- to the ldisc layer.
-
-start() - Ldisc notifier to the driver to start output.
-
-hangup() - Ask the tty driver to cause a hangup initiated
- from the host side. [Can sleep ??]
-
-break_ctl() - Send RS232 break. Can sleep. Can get called in
- parallel, driver must serialize (for now), and
- with write calls.
-
-wait_until_sent() - Wait for characters to exit the hardware queue
- of the driver. Can sleep
-
-send_xchar() - Send XON/XOFF and if possible jump the queue with
- it in order to get fast flow control responses.
- Cannot sleep ??

- * IXDP2x00-common PCI init
- *
- * The IXDP2[48]00 has a horrid PCI bus layout. Basically the board
- * contains two NPUs (ingress and egress) connected over PCI, both running
- * instances of the kernel. So far so good. Peers on the PCI bus running
- * Linux is a common design in telecom systems. The problem is that instead
- * of all the devices being controlled by a single host, different
- * devices are controlles by different NPUs on the same bus, leading to
- * multiple hosts on the bus.i The exact bus layout looks like:
- *
- * Bus 0
- * Master NPU <-------------------+-------------------> Slave NPU
- * |
- * |
- * P2P
- * |
- *
- * Bus 1 |
- * <--+------+---------+---------+------+-->
- * | | | | |
- * | | | | |
- * ... Dev PMC Media Eth0 Eth1 ...
- *
- * The master controlls all but Eth1, which is controlled by the
- * slave. What this measn is that the both the master and the slave
- * have to scan the bus, but only one of them can enumerate the bus.
- * In addition, after the bus is scaned, each kernel must remove
- * the device(s) it does not control from the PCI dev list otherwise
- * a driver on each NPU will try to manage it and we will have horrible
- * conflicts. Oh..and the slave NPU needs to see the master NPU
- * for Intel's drivers to work properly. Closed source drivers...
- *
- * The way we deal with this is fairly simple but ugly:
- *
- * 1) Let master scan and enumerate the bus completely.
- * 2) Master deletes Eth1 from device list.
- * 3) Slave scans bus and then deletes all but Eth1 (Eth0 on slave)
- * from device list.
- * 4) Find HW designers and LART them.
- *
- * The boards also do not do normal PCI IRQ routing, or any sort of
- * sensical swizzling, so we just need to check where on the bus a
- * device sits and figure out to which CPLD pin the interrupt is routed.
- * See ixdp2[48]00.c files.

- * setup.S Copyright (C) 1991, 1992 Linus Torvalds
- *
- * setup.s is responsible for getting the system data from the BIOS,
- * and putting them into the appropriate places in system memory.
- * both setup.s and system has been loaded by the bootblock.
- *
- * This code asks the bios for memory/disk/other parameters, and
- * puts them in a "safe" place: 0x90000-0x901FF, ie where the
- * boot-block used to be. It is then up to the protected mode
- * system to read them from there before the area is overwritten
- * for buffer-blocks.
- *
- * Move PS/2 aux init code to psaux.c
- * (troyer@saifr00.cfsat.Honeywell.COM) 03Oct92
- *
- * some changes and additional features by Christoph Niemann,
- * March 1993/June 1994 (Christoph.Niemann@linux.org)
- *
- * add APM BIOS checking by Stephen Rothwell, May 1994
- * (sfr@canb.auug.org.au)

- * by Hans Lermen & Werner Almesberger, February 1996

- *
- * Video handling moved to video.S by Martin Mares, March 1996
- * <mj@k332.feld.cvut.cz>
- *
- * Extended memory detection scheme retwiddled by orc@pell.chi.il.us (david
- * parsons) to avoid loadlin confusion, July 1997
- *
- * Transcribed from Intel (as86) -> AT&T (gas) by Chris Noe, May 1999.
- * <stiker@northlink.com>
- *
- * Fix to work around buggy BIOSes which dont use carry bit correctly
- * and/or report extended memory in CX/DX for e801h memory size detection
- * call. As a result the kernel got wrong figures. The int15/e801h docs
- * from Ralf Brown interrupt list seem to indicate AX/BX should be used
- * anyway. So to avoid breaking many machines (presumably there was a reason
- * to orginally use CX/DX instead of AX/BX), we do a kludge to see
- * if CX/DX have been changed in the e801 call and if so use AX/BX .

- *
- * "sleeping" and the contention routine ordering is protected

- *
- * Note that these functions are only called when there is
- * contention on the lock, and as such all this is the

- *
- * The JTLB is being read for the TLBP throughout the stall generated by the

- *
- * The software work-around is to not allow the instruction preceding the TLBP
- * to stall - make it an NOP or some other instruction guaranteed not to stall.
- *
- * Errata 2 will not be fixed. This errata is also on the R5000.

- help
- Say Y here if your target has the gdb-sh-stub
- package from www.m17n.org (or any conforming standard LinuxSH BIOS)
- in FLASH or EPROM. The kernel will use standard BIOS calls during
- boot for various housekeeping tasks (including calls to read and
- write characters to a system console, get a MAC address from an
- on-board Ethernet interface, and shut down the hardware). Note this
- does not work with machines with an existing operating system in

- * TODO (sorted by decreasing priority)

- * -- set readonly flag for CDs, set removable flag for CF readers
- * -- do inquiry and verify we got a disk and not a tape (for LUN mismatch)
- * -- support pphaneuf's SDDR-75 with two LUNs (also broken capacity...)
- * -- special case some senses, e.g. 3a/0 -> no media present, reduce retries
- * -- do something about spin-down devices, they are extremely dangerous
- * (ZIP is one. Needs spin-up command as well.)
- * -- verify the 13 conditions and do bulk resets
- * -- normal pool of commands instead of cmdv[]?
- * -- kill last_pipe and simply do two-state clearing on both pipes
- * -- verify protocol (bulk) from USB descriptors (maybe...)
- * -- highmem and sg
- * -- move top_sense and work_bcs into separate allocations (if they survive)
- * for cache purists and esoteric architectures.
- * -- prune comments, they are too volumnous
- * -- Exterminate P3 printks

- * From Jeff Daly:
- *
- * I2C adapter driver for Intel IXDP2xxx platforms. This should work for any
- * IXP2000 platform if it uses the HW GPIO in the same manner. Basically,
- * SDA and SCL GPIOs have external pullups. Setting the respective GPIO to
- * an input will make the signal a '1' via the pullup. Setting them to
- * outputs will pull them down.
- *
- * The GPIOs are open drain signals and are used as configuration strap inputs
- * during power-up so there's generally a buffer on the board that needs to be
- * 'enabled' to drive the GPIOs.

- * given address, one for each out-of-sync device. We model this by allocating
- * a number of r10_bio structures, one for each out-of-sync device.
- * As we setup these structures, we collect all bio's together into a list
- * which we then process collectively to add pages, and then process again

- * drivers/mtd/nand.c
- *
- * Overview:
- * This is the generic MTD driver for NAND flash devices. It should be
- * capable of working with almost all NAND chips currently available.
- *
- * Additional technical information is available on
- * http://www.linux-mtd.infradead.org/tech/nand.html
- *
- * Copyright (C) 2000 Steven J. Hill (sjhill@realitydiluted.com)
- * 2002 Thomas Gleixner (tglx@linutronix.de)
- *
- * 10-29-2001 Thomas Gleixner (tglx@linutronix.de)
- * - Changed nand_chip structure for controlline function to
- * support different hardware structures (Access to
- * controllines ALE,CLE,NCE via hardware specific function.
- * - exit out of "failed erase block" changed, to avoid
- * driver hangup
- * - init_waitqueue_head added in function nand_scan !!
- *
- * 01-30-2002 Thomas Gleixner (tglx@linutronix.de)
- * change in nand_writev to block invalid vecs entries
- *
- * 02-11-2002 Thomas Gleixner (tglx@linutronix.de)
- * - major rewrite to avoid duplicated code
- * common nand_write_page function
- * common get_chip function
- * - added oob_config structure for out of band layouts
- * - write_oob changed for partial programming
- * - read cache for faster access for subsequent reads
- * from the same page.
- * - support for different read/write address
- * - support for device ready/busy line
- * - read oob for more than one page enabled
- *
- * 02-27-2002 Thomas Gleixner (tglx@linutronix.de)
- * - command-delay can be programmed
- * - fixed exit from erase with callback-function enabled
- *
- * 03-21-2002 Thomas Gleixner (tglx@linutronix.de)
- * - DEBUG improvements provided by Elizabeth Clarke
- * (eclarke@aminocom.com)
- * - added zero check for this->chip_delay
- *
- * 04-03-2002 Thomas Gleixner (tglx@linutronix.de)
- * - added added hw-driver supplied command and wait functions
- * - changed blocking for erase (erase suspend enabled)
- * - check pointers before accessing flash provided by
- * John Hall (john.hall@optionexist.co.uk)
- *
- * 04-09-2002 Thomas Gleixner (tglx@linutronix.de)
- * - nand_wait repaired
- *
- * 04-28-2002 Thomas Gleixner (tglx@linutronix.de)
- * - OOB config defines moved to nand.h
- *
- * 08-01-2002 Thomas Gleixner (tglx@linutronix.de)
- * - changed my mailaddress, added pointer to tech/nand.html
- *
- * 08-07-2002 Thomas Gleixner (tglx@linutronix.de)
- * forced bad block location to byte 5 of OOB, even if
- * CONFIG_MTD_NAND_ECC_JFFS2 is not set, to prevent
- * erase /dev/mtdX from erasing bad blocks and destroying
- * bad block info
- *
- * 08-10-2002 Thomas Gleixner (tglx@linutronix.de)
- * Fixed writing tail of data. Thanks to Alice Hennessy
- * <ahennessy@mvista.com>.
- *
- * 08-10-2002 Thomas Gleixner (tglx@linutronix.de)
- * nand_read_ecc and nand_write_page restructured to support
- * hardware ECC. Thanks to Steven Hein (ssh@sgi.com)
- * for basic implementation and suggestions.
- * 3 new pointers in nand_chip structure:
- * calculate_ecc, correct_data, enabled_hwecc
- * forcing all hw-drivers to support page cache
- * eccvalid_pos is now mandatory
- *
- * 08-17-2002 tglx: fixed signed/unsigned missmatch in write.c
- * Thanks to Ken Offer <koffer@arlut.utexas.edu>
- *
- * 08-29-2002 tglx: use buffered read/write only for non pagealigned
- * access, speed up the aligned path by using the fs-buffer
- * reset chip removed from nand_select(), implicit done
- * only, when erase is interrupted
- * waitfuntion use yield, instead of schedule_timeout
- * support for 6byte/512byte hardware ECC
- * read_ecc, write_ecc extended for different oob-layout
- * selections: Implemented NAND_NONE_OOB, NAND_JFFS2_OOB,
- * NAND_YAFFS_OOB. fs-driver gives one of these constants
- * to select the oob-layout fitting the filesystem.
- * oobdata can be read together with the raw data, when
- * the fs-driver supplies a big enough buffer.
- * size = 12 * number of pages to read (256B pagesize)
- * 24 * number of pages to read (512B pagesize)
- * the buffer contains 8/16 byte oobdata and 4/8 byte
- * returncode from calculate_ecc
- * oobdata can be given from filesystem to program them
- * in one go together with the raw data. ECC codes are
- * filled in at the place selected by oobsel.
- *
- * 09-04-2002 tglx: fixed write_verify (John Hall (john.hall@optionexist.co.uk))
- *
- * 11-11-2002 tglx: fixed debug output in nand_write_page
- * (John Hall (john.hall@optionexist.co.uk))
- *
- * 11-25-2002 tglx: Moved device ID/ manufacturer ID from nand_ids.h
- * Splitted device ID and manufacturer ID table.
- * Removed CONFIG_MTD_NAND_ECC, as it defaults to ECC_NONE for
- * mtd->read / mtd->write and is controllable by the fs driver
- * for mtd->read_ecc / mtd->write_ecc
- * some minor cleanups
- *
- * 12-05-2002 tglx: Dave Ellis (DGE@sixnetio) provided the fix for
- * WRITE_VERIFY long time ago. Thanks for remembering me.
- *
- * 02-14-2003 tglx: Reject non page aligned writes
- * Fixed ecc select in nand_write_page to match semantics.
- *
- * 02-18-2003 tglx: Changed oobsel to pointer. Added a default oob-selector
- *
- * 02-18-2003 tglx: Implemented oobsel again. Now it uses a pointer to
- + a structure, which will be supplied by a filesystem driver
- * If NULL is given, then the defaults (none or defaults
- * supplied by ioctl (MEMSETOOBSEL) are used.
- * For partitions the partition defaults are used (mtdpart.c)
- *
- * 06-04-2003 tglx: fix compile errors and fix write verify problem for
- * some chips, which need either a delay between the readback
- * and the next write command or have the CE removed. The
- * CE disable/enable is much faster than a 20us delay and
- * it should work on all available chips.

- * Gianfar Ethernet Driver
- * Driver for FEC on MPC8540 and TSEC on MPC8540/MPC8560

- * Gianfar: AKA Lambda Draconis, "Dragon"
- * RA 11 31 24.2
- * Dec +69 19 52
- * V 3.84
- * B-V +1.62
- *
- * Theory of operation
- * This driver is designed for the Triple-speed Ethernet
- * controllers on the Freescale 8540/8560 integrated processors,
- * as well as the Fast Ethernet Controller on the 8540.
- *
- * The driver is initialized through OCP. Structures which
- * define the configuration needed by the board are defined in a
- * board structure in arch/ppc/platforms (though I do not
- * discount the possibility that other architectures could one
- * day be supported. One assumption the driver currently makes
- * is that the PHY is configured in such a way to advertise all
- * capabilities. This is a sensible default, and on certain
- * PHYs, changing this default encounters substantial errata
- * issues. Future versions may remove this requirement, but for
- * now, it is best for the firmware to ensure this is the case.
- *
- * The Gianfar Ethernet Controller uses a ring of buffer
- * descriptors. The beginning is indicated by a register
- * pointing to the physical address of the start of the ring.
- * The end is determined by a "wrap" bit being set in the
- * last descriptor of the ring.
- *
- * When a packet is received, the RXF bit in the
- * IEVENT register is set, triggering an interrupt when the
- * corresponding bit in the IMASK register is also set (if
- * interrupt coalescing is active, then the interrupt may not
- * happen immediately, but will wait until either a set number
- * of frames or amount of time have passed.). In NAPI, the
- * interrupt handler will signal there is work to be done, and
- * exit. Without NAPI, the packet(s) will be handled
- * immediately. Both methods will start at the last known empty
- * descriptor, and process every subsequent descriptor until there
- * are none left with data (NAPI will stop after a set number of
- * packets to give time to other tasks, but will eventually
- * process all the packets). The data arrives inside a
- * pre-allocated skb, and so after the skb is passed up to the
- * stack, a new skb must be allocated, and the address field in
- * the buffer descriptor must be updated to indicate this new
- * skb.
- *
- * When the kernel requests that a packet be transmitted, the
- * driver starts where it left off last time, and points the
- * descriptor at the buffer which was passed in. The driver
- * then informs the DMA engine that there are packets ready to
- * be transmitted. Once the controller is finished transmitting
- * the packet, an interrupt may be triggered (under the same
- * conditions as for reception, but depending on the TXF bit).
- * The driver then cleans up the buffer.

- * Marvell's Gigabit Ethernet controller low level driver
- *
- * DESCRIPTION:
- * This file introduce low level API to Marvell's Gigabit Ethernet
- * controller. This Gigabit Ethernet Controller driver API controls
- * 1) Operations (i.e. port init, start, reset etc').
- * 2) Data flow (i.e. port send, receive etc').
- * Each Gigabit Ethernet port is controlled via
- * struct mv64340_private.
- * This struct includes user configuration information as well as
- * driver internal data needed for its operations.
- *
- * Supported Features:
- * - This low level driver is OS independent. Allocating memory for
- * the descriptor rings and buffers are not within the scope of
- * this driver.
- * - The user is free from Rx/Tx queue managing.
- * - This low level driver introduce functionality API that enable
- * the to operate Marvell's Gigabit Ethernet Controller in a
- * convenient way.
- * - Simple Gigabit Ethernet port operation API.
- * - Simple Gigabit Ethernet port data flow API.
- * - Data flow and operation API support per queue functionality.
- * - Support cached descriptors for better performance.
- * - Enable access to all four DRAM banks and internal SRAM memory
- * spaces.
- * - PHY access and control API.
- * - Port control register configuration API.
- * - Full control over Unicast and Multicast MAC configurations.
- *
- * Operation flow:
- *
- * Initialization phase
- * This phase complete the initialization of the the mv64340_private
- * struct.
- * User information regarding port configuration has to be set
- * prior to calling the port initialization routine.
- *
- * In this phase any port Tx/Rx activity is halted, MIB counters
- * are cleared, PHY address is set according to user parameter and
- * access to DRAM and internal SRAM memory spaces.
- *
- * Driver ring initialization
- * Allocating memory for the descriptor rings and buffers is not
- * within the scope of this driver. Thus, the user is required to
- * allocate memory for the descriptors ring and buffers. Those
- * memory parameters are used by the Rx and Tx ring initialization
- * routines in order to curve the descriptor linked list in a form
- * of a ring.
- * Note: Pay special attention to alignment issues when using
- * cached descriptors/buffers. In this phase the driver store
- * information in the mv64340_private struct regarding each queue
- * ring.
- *
- * Driver start
- * This phase prepares the Ethernet port for Rx and Tx activity.
- * It uses the information stored in the mv64340_private struct to
- * initialize the various port registers.
- *
- * Data flow:
- * All packet references to/from the driver are done using
- * struct pkt_info.
- * This struct is a unified struct used with Rx and Tx operations.
- * This way the user is not required to be familiar with neither
- * Tx nor Rx descriptors structures.
- * The driver's descriptors rings are management by indexes.
- * Those indexes controls the ring resources and used to indicate
- * a SW resource error:
- * 'current'
- * This index points to the current available resource for use. For
- * example in Rx process this index will point to the descriptor
- * that will be passed to the user upon calling the receive routine.
- * In Tx process, this index will point to the descriptor
- * that will be assigned with the user packet info and transmitted.
- * 'used'
- * This index points to the descriptor that need to restore its
- * resources. For example in Rx process, using the Rx buffer return
- * API will attach the buffer returned in packet info to the
- * descriptor pointed by 'used'. In Tx process, using the Tx
- * descriptor return will merely return the user packet info with
- * the command status of the transmitted buffer pointed by the
- * 'used' index. Nevertheless, it is essential to use this routine
- * to update the 'used' index.
- * 'first'
- * This index supports Tx Scatter-Gather. It points to the first
- * descriptor of a packet assembled of multiple buffers. For example
- * when in middle of Such packet we have a Tx resource error the
- * 'curr' index get the value of 'first' to indicate that the ring
- * returned to its state before trying to transmit this packet.
- *
- * Receive operation:
- * The eth_port_receive API set the packet information struct,
- * passed by the caller, with received information from the
- * 'current' SDMA descriptor.
- * It is the user responsibility to return this resource back
- * to the Rx descriptor ring to enable the reuse of this source.
- * Return Rx resource is done using the eth_rx_return_buff API.
- *
- * Transmit operation:
- * The eth_port_send API supports Scatter-Gather which enables to
- * send a packet spanned over multiple buffers. This means that
- * for each packet info structure given by the user and put into
- * the Tx descriptors ring, will be transmitted only if the 'LAST'
- * bit will be set in the packet info command status field. This
- * API also consider restriction regarding buffer alignments and
- * sizes.
- * The user must return a Tx resource after ensuring the buffer
- * has been transmitted to enable the Tx ring indexes to update.
- *
- * BOARD LAYOUT
- * This device is on-board. No jumper diagram is necessary.
- *
- * EXTERNAL INTERFACE
- *
- * Prior to calling the initialization routine eth_port_init() the user
- * must set the following fields under mv64340_private struct:
- * port_num User Ethernet port number.
- * port_mac_addr[6] User defined port MAC address.
- * port_config User port configuration value.
- * port_config_extend User port config extend value.
- * port_sdma_config User port SDMA config value.
- * port_serial_control User port serial control value.
- *
- * This driver introduce a set of default values:
- * PORT_CONFIG_VALUE Default port configuration value
- * PORT_CONFIG_EXTEND_VALUE Default port extend configuration value
- * PORT_SDMA_CONFIG_VALUE Default sdma control value
- * PORT_SERIAL_CONTROL_VALUE Default port serial control value
- *
- * This driver data flow is done using the struct pkt_info which
- * is a unified struct for Rx and Tx operations:
- *
- * byte_cnt Tx/Rx descriptor buffer byte count.
- * l4i_chk CPU provided TCP Checksum. For Tx operation
- * only.
- * cmd_sts Tx/Rx descriptor command status.
- * buf_ptr Tx/Rx descriptor buffer pointer.
- * return_info Tx/Rx user resource return information.

- * If the routine get into Tx resource error it assigns 'curr' index as
- * 'first'. This way the function can abort Tx process of multiple
- * descriptors per packet.

- * ETH_ERROR in case the routine can not access Tx desc ring.
- * ETH_QUEUE_LAST_RESOURCE if the routine uses the last Tx resource.

- NEx000-clone boards have a Station Address PROM (SAPROM) in the packet
- buffer memory space. NE2000 clones have 0x57,0x57 in bytes 0x0e,0x0f of
- the SAPROM, while other supposed NE2000 clones must be detected by their
- SA prefix.
-
- Reading the SAPROM from a word-wide card with the 8390 set in byte-wide
- mode results in doubled values, which can be detected and compensated for.
-
- The probe is also responsible for initializing the card and filling
- in the 'dev' and 'ei_status' structures.
-
- We use the minimum memory size for some ethercard product lines, iff we can't
- distinguish models. You can increase the packet buffer size by setting
- PACKETBUF_MEMSIZE. Reported Cabletron packet buffer locations are:
- E1010 starts at 0x100 and ends at 0x2000.
- E1010-x starts at 0x100 and ends at 0x8000. ("-x" means "more memory")

- * ------------------------------------------------------------
- * Emulation of a SCSI host adapter for Virtual I/O devices
- *
- * This driver supports the SCSI adapter implemented by the IBM
- * Power5 firmware. That SCSI adapter is not a physical adapter,
- * but allows Linux SCSI peripheral drivers to directly
- * access devices in another logical partition on the physical system.
- *
- * The virtual adapter(s) are present in the open firmware device
- * tree just like real adapters.
- *
- * One of the capabilities provided on these systems is the ability
- * to DMA between partitions. The architecture states that for VSCSI,
- * the server side is allowed to DMA to and from the client. The client
- * is never trusted to DMA to or from the server directly.
- *
- * Messages are sent between partitions on a "Command/Response Queue"
- * (CRQ), which is just a buffer of 16 byte entries in the receiver's
- * Senders cannot access the buffer directly, but send messages by
- * making a hypervisor call and passing in the 16 bytes. The hypervisor
- * puts the message in the next 16 byte space in round-robbin fashion,
- * turns on the high order bit of the message (the valid bit), and
- * generates an interrupt to the receiver (if interrupts are turned on.)
- * The receiver just turns off the valid bit when they have copied out
- * the message.
- *
- * The VSCSI client builds a SCSI Remote Protocol (SRP) Information Unit
- * (IU) (as defined in the T10 standard available at www.t10.org), gets
- * a DMA address for the message, and sends it to the server as the
- * payload of a CRQ message. The server DMAs the SRP IU and processes it,
- * including doing any additional data transfers. When it is done, it
- * DMAs the SRP response back to the same address as the request came from,
- * and sends a CRQ message back to inform the client that the request has
- * completed.
- *
- * Note that some of the underlying infrastructure is different between
- * machines conforming to the "RS/6000 Platform Architecture" (RPA) and
- * the older iSeries hypervisor models. To support both, some low level
- * routines have been broken out into rpa_vscsi.c and iseries_vscsi.c.
- * The Makefile should pick one, not two, not zero, of these.
- *
- * TODO: This is currently pretty tied to the IBM i/pSeries hypervisor
- * interfaces. It would be really nice to abstract this above an RDMA
- * layer.

- * drivers/serial/mpsc/mpsc.c
- *
- * Generic driver for the MPSC (UART mode) on Marvell parts (e.g., GT64240,
- * GT64260, MV64340, MV64360, GT96100, ... ).
- *
- * Author: Mark A. Greer <mgreer@mvista.com>
- *
- * Based on an old MPSC driver that was in the linuxppc tree. It appears to
- * have been created by Chris Zankel (formerly of MontaVista) but there
- * is no proper Copyright so I'm not sure. Parts were, apparently, also
- * taken from PPCBoot (now U-Boot). Also based on drivers/serial/8250.c
- * by Russell King.

-/*
- * The MPSC interface is much like a typical network controller's interface.
- * That is, you set up separate rings of descriptors for transmitting and
- * receiving data. There is also a pool of buffers with (one buffer per
- * descriptor) that incoming data are dma'd into or outgoing data are dma'd
- * out of.
- *
- * The MPSC requires two other controllers to be able to work. The Baud Rate
- * Generator (BRG) provides a clock at programmable frequencies which determines
- * the baud rate. The Serial DMA Controller (SDMA) takes incoming data from the
- * MPSC and DMA's it into memory or DMA's outgoing data and passes it to the
- * MPSC. It is actually the SDMA interrupt that the driver uses to keep the
- * transmit and receive "engines" going (i.e., indicate data has been
- * transmitted or received).
- *
- * NOTES:
- *
- * 1) Some chips have an erratum where several regs cannot be
- * read. To work around that, we keep a local copy of those regs in
- * 'mpsc_port_info_t' and use the *_M macros when accessing those regs.
- *
- * 2) Some chips have an erratum where the chip will hang when the SDMA ctlr
- * accesses system mem in a cache coherent region. This *should* be a
- * show-stopper when coherency is turned on but it seems to work okay as
- * long as there are no snoop hits. Therefore, there are explicit cache
- * management macros in addition to the dma_* calls--the dma_* calls don't
- * do cache mgmt on coherent systems--to manage the cache ensuring there
- * are no snoop hits.
- *
- * 3) AFAICT, hardware flow control isn't supported by the controller --MAG.

- * The OMAP UDC needs _very_ early endpoint setup: before enabling the

- * framework to use from usb_endpoint_enable(), which happens after
- * enumeration as part of activating an interface. (But if we add an
- * optional new "UDC not yet running" state to the gadget driver model,
- * even just during driver binding, the endpoint autoconfig logic is the
- * natural spot to manufacture new endpoints.)
- *
- * So instead of using endpoint enable calls to control the hardware setup,
- * this driver defines a "fifo mode" parameter. It's used during driver
- * initialization to choose among a set of pre-defined endpoint configs.
- * See omap_udc_setup() for available modes, or to add others. That code
- * lives in an init section, so use this driver as a module if you need
- * to change the fifo mode after the kernel boots.
- *
- * Gadget drivers normally ignore endpoints they don't care about, and
- * won't include them in configuration descriptors. That means only
- * misbehaving hosts would even notice they exist.

- *
- * Allocate @count clusters preferably starting at cluster @start_lcn or at the

- * @vol. @zone is either DATA_ZONE for allocation of normal clusters or
- * MFT_ZONE for allocation of clusters for the master file table, i.e. the
- * $MFT/$DATA attribute.
- *
- * @start_vcn specifies the vcn of the first allocated cluster. This makes
- * merging the resulting runlist with the old runlist easier.
- *
- * You need to check the return value with IS_ERR(). If this is false, the
- * function was successful and the return value is a runlist describing the
- * allocated cluster(s). If IS_ERR() is true, the function failed and
- * PTR_ERR() gives you the error code.
- *
- * Notes on the allocation algorithm
- * =================================
- *
- * There are two data zones. First is the area between the end of the mft zone
- * and the end of the volume, and second is the area between the start of the
- * volume and the start of the mft zone. On unmodified/standard NTFS 1.x
- * volumes, the second data zone does not exist due to the mft zone being
- * expanded to cover the start of the volume in order to reserve space for the
- * mft bitmap attribute.
- *
- * This is not the prettiest function but the complexity stems from the need of
- * implementing the mft vs data zoned approach and from the fact that we have
- * access to the lcn bitmap in portions of up to 8192 bytes at a time, so we
- * need to cope with crossing over boundaries of two buffers. Further, the
- * fact that the allocator allows for caller supplied hints as to the location
- * of where allocation should begin and the fact that the allocator keeps track
- * of where in the data zones the next natural allocation should occur,
- * contribute to the complexity of the function. But it should all be
- * worthwhile, because this allocator should: 1) be a full implementation of
- * the MFT zone approach used by Windows NT, 2) cause reduction in
- * fragmentation, and 3) be speedy in allocations (the code is not optimized
- * for speed, but the algorithm is, so further speed improvements are probably
- * possible).
- *
- * FIXME: We should be monitoring cluster allocation and increment the MFT zone
- * size dynamically but this is something for the future. We will just cause
- * heavier fragmentation by not doing it and I am not even sure Windows would
- * grow the MFT zone dynamically, so it might even be correct not to do this.
- * The overhead in doing dynamic MFT zone expansion would be very large and
- * unlikely worth the effort. (AIA)
- *
- * TODO: I have added in double the required zone position pointer wrap around
- * logic which can be optimized to having only one of the two logic sets.
- * However, having the double logic will work fine, but if we have only one of
- * the sets and we get it wrong somewhere, then we get into trouble, so
- * removing the duplicate logic requires _very_ careful consideration of _all_
- * possible code paths. So at least for now, I am leaving the double logic -
- * better safe than sorry... (AIA)
- *
- * Locking: - The volume lcn bitmap must be unlocked on entry and is unlocked
- * on return.
- * - This function takes the volume lcn bitmap lock for writing and

- * read_barrier_depends - Flush all pending reads that subsequents reads
- * depend on.
- *
- * No data-dependent reads from memory-like regions are ever reordered
- * over this barrier. All reads preceding this primitive are guaranteed
- * to access memory (but not necessarily other CPUs' caches) before any
- * reads following this primitive that depend on the data return by
- * any of the preceding reads. This primitive is much lighter weight than
- * rmb() on most CPUs, and is never heavier weight than is
- * rmb().
- *
- * These ordering constraints are respected by both the local CPU
- * and the compiler.
- *
- * Ordering is not guaranteed by anything other than these primitives,
- * not even by data dependencies. See the documentation for
- * memory_barrier() for examples and URLs to more information.
- *
- * For example, the following code would force ordering (the initial
- * value of "a" is zero, "b" is one, and "p" is "&a"):
- *
- * <programlisting>
- * CPU 0 CPU 1
- *
- * b = 2;
- * memory_barrier();
- * p = &b; q = p;
- * read_barrier_depends();
- * d = *q;
- * </programlisting>
- *
- *
- * because the read of "*q" depends on the read of "p" and these
- * two reads are separated by a read_barrier_depends(). However,
- * the following code, with the same initial values for "a" and "b":
- *
- * <programlisting>
- * CPU 0 CPU 1
- *
- * a = 2;
- * memory_barrier();
- * b = 3; y = b;
- * read_barrier_depends();
- * x = a;
- * </programlisting>
- *
- * does not enforce ordering, since there is no data dependency between
- * the read of "a" and the read of "b". Therefore, on some CPUs, such
- * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
- * in cases like thiswhere there are no data dependencies.

- * DATA: The data area is stored. We use current->end_text to
- * current->brk to pick up all of the user variables, plus any memory
- * that may have been sbrk'ed. No attempt is made to determine if a
- * page is demand-zero or if a page is totally unused, we just cover

- * that an integral number of pages is written.
- * STACK: We need the stack information in order to get a meaningful

- * When kexec transitions to the new kernel there is a one-to-one
- * mapping between physical and virtual addresses. On processors
- * where you can disable the MMU this is trivial, and easy. For
- * others it is still a simple predictable page table to setup.
- *
- * In that environment kexec copies the new kernel to its final
- * resting place. This means I can only support memory whose
- * physical address can fit in an unsigned long. In particular
- * addresses where (pfn << PAGE_SHIFT) > ULONG_MAX cannot be handled.
- * If the assembly stub has more restrictive requirements
- * KEXEC_SOURCE_MEMORY_LIMIT and KEXEC_DEST_MEMORY_LIMIT can be
- * defined more restrictively in <asm/kexec.h>.
- *
- * The code for the transition from the current kernel to the
- * the new kernel is placed in the control_code_buffer, whose size
- * is given by KEXEC_CONTROL_CODE_SIZE. In the best case only a single
- * page of memory is necessary, but some architectures require more.
- * Because this memory must be identity mapped in the transition from
- * virtual to physical addresses it must live in the range
- * 0 - TASK_SIZE, as only the user space mappings are arbitrarily
- * modifiable.
- *
- * The assembly stub in the control code buffer is passed a linked list
- * of descriptor pages detailing the source pages of the new kernel,
- * and the destination addresses of those source pages. As this data
- * structure is not used in the context of the current OS, it must
- * be self-contained.
- *
- * The code has been made to work with highmem pages and will use a
- * destination page in its final resting place (if it happens
- * to allocate it). The end product of this is that most of the
- * physical address space, and most of RAM can be used.
- *
- * Future directions include:
- * - allocating a page table with the control code buffer identity
- * mapped, to simplify machine_kexec and make kexec_on_panic more
- * reliable.

- This code is NOT intended to be used for statistics collection,
- its purpose is to provide a base for statistical multiplexing
- for controlled load service.
- If you need only statistics, run a user level daemon which
- periodically reads byte counters.
-
- Unfortunately, rate estimation is not a very easy task.
- F.e. I did not find a simple way to estimate the current peak rate
- and even failed to formulate the problem 8)8)
-
- So I preferred not to built an estimator into the scheduler,
- but run this task separately.
- Ideally, it should be kernel thread(s), but for now it runs
- from timers, which puts apparent top bounds on the number of rated
- flows, has minimal overhead on small, but is enough
- to handle controlled load service, sets of aggregates.
-
- We measure rate over A=(1<<interval) seconds and evaluate EWMA:
-
- avrate = avrate*(1-W) + rate*W
-
- where W is chosen as negative power of 2: W = 2^(-ewma_log)
-
- The resulting time constant is:
-
- T = A/(-ln(1-W))
-
-
- NOTES.
-
- * The stored value for avbps is scaled by 2^5, so that maximal
- rate is ~1Gbit, avpps is scaled by 2^10.
-
- * Minimal interval is HZ/4=250msec (it is the greatest common divisor
- for HZ=100 and HZ=1024 8)), maximal interval
- is (HZ*2^EST_MAX_INTERVAL)/4 = 8sec. Shorter intervals
- are too expensive, longer ones can be implemented
- at user level painlessly.

- * ip_conntrack_proto_gre.c - Version 2.0
- *
- * Connection tracking protocol helper module for GRE.
- *
- * GRE is a generic encapsulation protocol, which is generally not very
- * suited for NAT, as it has no protocol-specific part as port numbers.
- *
- * It has an optional key field, which may help us distinguishing two
- * connections between the same two hosts.
- *
- * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
- *
- * PPTP is built on top of a modified version of GRE, and has a mandatory
- * field called "CallID", which serves us for the same purpose as the key
- * field in plain GRE.
- *
- * Documentation about PPTP can be found in RFC 2637

- * ip_nat_proto_gre.c - Version 2.0
- *
- * NAT protocol helper module for GRE.
- *
- * GRE is a generic encapsulation protocol, which is generally not very
- * suited for NAT, as it has no protocol-specific part as port numbers.
- *
- * It has an optional key field, which may help us distinguishing two
- * connections between the same two hosts.
- *
- * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
- *
- * PPTP is built on top of a modified version of GRE, and has a mandatory
- * field called "CallID", which serves us for the same purpose as the key
- * field in plain GRE.
- *
- * Documentation about PPTP can be found in RFC 2637
- *
- * (C) 2000-2004 by Harald Welte <laforge@gnumonks.org>
- *

-/* Clark-Shenker-Zhang algorithm.
- =======================================
-
- SOURCE.
-
- David D. Clark, Scott Shenker and Lixia Zhang
- "Supporting Real-Time Applications in an Integrated Services Packet
- Network: Architecture and Mechanism".
-
- CBQ presents a flexible universal algorithm for packet scheduling,
- but it has pretty poor delay characteristics.
- Round-robin scheduling and link-sharing goals
- apparently contradict minimization of network delay and jitter.
- Moreover, correct handling of predictive flows seems to be
- impossible in CBQ.
-
- CSZ presents a more precise but less flexible and less efficient
- approach. As I understand it, the main idea is to create
- WFQ flows for each guaranteed service and to allocate
- the rest of bandwidth to dummy flow-0. Flow-0 comprises
- the predictive services and the best effort traffic;
- it is handled by a priority scheduler with the highest
- priority band allocated for predictive services, and the rest ---
- to the best effort packets.
-
- Note that in CSZ flows are NOT limited to their bandwidth. It
- is supposed that the flow passed admission control at the edge
- of the QoS network and it doesn't need further shaping. Any
- attempt to improve the flow or to shape it to a token bucket
- at intermediate hops will introduce undesired delays and raise
- jitter.
-
- At the moment CSZ is the only scheduler that provides
- true guaranteed service. Another schemes (including CBQ)
- do not provide guaranteed delay and randomize jitter.
- There is a proof (Sally Floyd), that delay
- can be estimated by a IntServ compliant formula.
- This result is true formally, but it is wrong in principle.
- It takes into account only round-robin delays,
- ignoring delays introduced by link sharing i.e. overlimiting.
- Note that temporary overlimits are inevitable because
- real links are not ideal, and the real algorithm must take this
- into account.
-
- ALGORITHM.
-
- --- Notations.
-
- $B$ is link bandwidth (bits/sec).
-
- $I$ is set of all flows, including flow $0$.
- Every flow $a \in I$ has associated bandwidth slice $r_a < 1$ and
- $\sum_{a \in I} r_a = 1$.
-
- --- Flow model.
-
- Let $m_a$ is the number of backlogged bits in flow $a$.
- The flow is {\em active}, if $m_a > 0$.
- This number is a discontinuous function of time;
- when a packet $i$ arrives:
- \[
- m_a(t_i+0) - m_a(t_i-0) = L^i,
- \]
- where $L^i$ is the length of the arrived packet.
- The flow queue is drained continuously until $m_a == 0$:
- \[
- {d m_a \over dt} = - { B r_a \over \sum_{b \in A} r_b}.
- \]
- I.e. flow rates are their allocated rates proportionally
- scaled to take all available link bandwidth. Apparently,
- it is not the only possible policy. F.e. CBQ classes
- without borrowing would be modelled by:
- \[
- {d m_a \over dt} = - B r_a .
- \]
- More complicated hierarchical bandwidth allocation
- policies are possible, but unfortunately, the basic
- flow equations have a simple solution only for proportional
- scaling.
-
- --- Departure times.
-
- We calculate the time until the last bit of packet is sent:
- \[
- E_a^i(t) = { m_a(t_i) - \delta_a(t) \over r_a },
- \]
- where $\delta_a(t)$ is number of bits drained since $t_i$.
- We have to evaluate $E_a^i$ for all queued packets,
- then find the packet with minimal $E_a^i$ and send it.
-
- This sounds good, but direct implementation of the algorithm
- is absolutely infeasible. Luckily, if flow rates
- are scaled proportionally, the equations have a simple solution.
-
- The differential equation for $E_a^i$ is
- \[
- {d E_a^i (t) \over dt } = - { d \delta_a(t) \over dt} { 1 \over r_a} =
- { B \over \sum_{b \in A} r_b}
- \]
- with initial condition
- \[
- E_a^i (t_i) = { m_a(t_i) \over r_a } .
- \]
-
- Let's introduce an auxiliary function $R(t)$:
-
- --- Round number.
-
- Consider the following model: we rotate over active flows,
- sending $r_a B$ bits from every flow, so that we send
- $B \sum_{a \in A} r_a$ bits per round, that takes
- $\sum_{a \in A} r_a$ seconds.
-
- Hence, $R(t)$ (round number) is a monotonically increasing
- linear function of time when $A$ is not changed
- \[
- { d R(t) \over dt } = { 1 \over \sum_{a \in A} r_a }
- \]
- and it is continuous when $A$ changes.
-
- The central observation is that the quantity
- $F_a^i = R(t) + E_a^i(t)/B$ does not depend on time at all!
- $R(t)$ does not depend on flow, so that $F_a^i$ can be
- calculated only once on packet arrival, and we need not
- recalculate $E$ numbers and resorting queues.
- The number $F_a^i$ is called finish number of the packet.
- It is just the value of $R(t)$ when the last bit of packet
- is sent out.
-
- Maximal finish number on flow is called finish number of flow
- and minimal one is "start number of flow".
- Apparently, flow is active if and only if $F_a \leq R$.
-
- When a packet of length $L_i$ bit arrives to flow $a$ at time $t_i$,
- we calculate $F_a^i$ as:
-
- If flow was inactive ($F_a < R$):
- $F_a^i = R(t) + {L_i \over B r_a}$
- otherwise
- $F_a^i = F_a + {L_i \over B r_a}$
-
- These equations complete the algorithm specification.
-
- It looks pretty hairy, but there is a simple
- procedure for solving these equations.
- See procedure csz_update(), that is a generalization of
- the algorithm from S. Keshav's thesis Chapter 3
- "Efficient Implementation of Fair Queuing".
-
- NOTES.
-
- * We implement only the simplest variant of CSZ,
- when flow-0 is a explicit 4band priority fifo.
- This is bad, but we need a "peek" operation in addition
- to "dequeue" to implement complete CSZ.
- I do not want to do that, unless it is absolutely
- necessary.
-
- * A primitive support for token bucket filtering
- presents itself too. It directly contradicts CSZ, but
- even though the Internet is on the globe ... :-)
- "the edges of the network" really exist.
-
- BUGS.
-
- * Fixed point arithmetic is overcomplicated, suboptimal and even
- wrong. Check it later. */

-# D = Initialised data
-# G = Initialised data for small objects

-# N = Debugging symbol

-# U - undefined global symbols
-# w - local weak symbols
-
-# readprofile starts reading symbols when _stext is found, and
-# continue until it finds a symbol which is not either of 'T', 't',
-# 'W' or 'w'. __crc_ are 'A' and placed in the middle

-# namespace.pl. Mon Aug 30 2004
-#
-# Perform a name space analysis on the linux kernel.
-#
-# Copyright Keith Owens <kaos@ocs.com.au>. GPL.
-#
-# Invoke by changing directory to the top of the kernel object
-# tree then namespace.pl, no parameters.
-#
-# Tuned for 2.1.x kernels with the new module handling, it will
-# work with 2.0 kernels as well.
-#
-# Last change 2.6.9-rc1, adding support for separate source and object
-# trees.
-#
-# The source must be compiled/assembled first, the object files
-# are the primary input to this script. Incomplete or missing
-# objects will result in a flawed analysis. Compile both vmlinux
-# and modules.
-#
-# Even with complete objects, treat the result of the analysis
-# with caution. Some external references are only used by
-# certain architectures, others with certain combinations of
-# configuration parameters. Ideally the source should include
-# something like
-#
-# #ifndef CONFIG_...
-# static
-# #endif
-# symbol_definition;
-#
-# so the symbols are defined as static unless a particular
-# CONFIG_... requires it to be external.
-#
-# A symbol that is suffixed with '(export only)' has these properties
-#
-# * It is global.
-# * It is marked EXPORT_SYMBOL or EXPORT_SYMBOL_GPL, either in the same
-# source file or a different source file.
-# * Given the current .config, nothing uses the symbol.
-#
-# The symbol is a candidate for conversion to static, plus removal of the
-# export. But be careful that a different .config might use the symbol.
-#
-#
-# Name space analysis and cleanup is an iterative process. You cannot
-# expect to find all the problems in a single pass.
-#
-# * Identify possibly unnecessary global declarations, verify that they
-# really are unnecessary and change them to static.
-# * Compile and fix up gcc warnings about static, removing dead symbols
-# as necessary.
-# * make clean and rebuild with different configs (especially
-# CONFIG_MODULES=n) to see which symbols are being defined when the
-# config does not require them. These symbols bloat the kernel object
-# for no good reason, which is frustrating for embedded systems.
-# * Wrap config sensitive symbols in #ifdef CONFIG_foo, as long as the
-# code does not get too ugly.
-# * Repeat the name space analysis until you can live with with the
-# result.

- * usbus428.c - ALSA USB US-428 Driver

-2004-07-13 Karsten Wiese
- Version 0.7.1:
- Don't sleep in START/STOP callbacks anymore.
- us428 channels C/D not handled just for this version, sorry.
-
-2004-06-21 Karsten Wiese
- Version 0.6.4:
- Temporarely suspend midi input
- to sanely call usb_set_interface() when setting format.
-
-2004-06-12 Karsten Wiese
- Version 0.6.3:
- Made it thus the following rule is enforced:
- "All pcm substreams of one usX2Y have to operate at the same rate & format."
-
-2004-04-06 Karsten Wiese
- Version 0.6.0:
- Runs on 2.6.5 kernel without any "--with-debug=" things.
- us224 reported running.
-
-2004-01-14 Karsten Wiese
- Version 0.5.1:
- Runs with 2.6.1 kernel.
-
-2003-12-30 Karsten Wiese
- Version 0.4.1:
- Fix 24Bit 4Channel capturing for the us428.
-
-2003-11-27 Karsten Wiese, Martin Langer
- Version 0.4:
- us122 support.
- us224 could be tested by uncommenting the sections containing USB_ID_US224
-
-2003-11-03 Karsten Wiese
- Version 0.3:
- 24Bit support.
- "arecord -D hw:1 -c 2 -r 48000 -M -f S24_3LE|aplay -D hw:1 -c 2 -r 48000 -M -f S24_3LE" works.
-
-2003-08-22 Karsten Wiese
- Version 0.0.8:
- Removed EZUSB Firmware. First Stage Firmwaredownload is now done by tascam-firmware downloader.
- See:
- http://usb-midi-fw.sourceforge.net/tascam-firmware.tar.gz
-
-2003-06-18 Karsten Wiese
- Version 0.0.5:
- changed to compile with kernel 2.4.21 and alsa 0.9.4
-
-2002-10-16 Karsten Wiese
- Version 0.0.4:
- compiles again with alsa-current.
- USB_ISO_ASAP not used anymore (most of the time), instead
- urb->start_frame is calculated here now, some calls inside usb-driver don't need to happen anymore.
-
- To get the best out of this:
- Disable APM-support in the kernel as APM-BIOS calls (once each second) hard disable interrupt for many precious milliseconds.
- This helped me much on my slowish PII 400 & PIII 500.
- ACPI yet untested but might cause the same bad behaviour.
- Use a kernel with lowlatency and preemptiv patches applied.
- To autoload snd-usb-midi append a line
- post-install snd-usb-us428 modprobe snd-usb-midi
- to /etc/modules.conf.
-
- known problems:
- sliders, knobs, lights not yet handled except MASTER Volume slider.
- "pcm -c 2" doesn't work. "pcm -c 2 -m direct_interleaved" does.
- KDE3: "Enable full duplex operation" deadlocks.
-
-
-2002-08-31 Karsten Wiese
- Version 0.0.3: audio also simplex;
- simplifying: iso urbs only 1 packet, melted structs.
- ASYNC_UNLINK not used anymore: no more crashes so far.....
- for alsa 0.9 rc3.
-
-2002-08-09 Karsten Wiese
- Version 0.0.2: midi works with snd-usb-midi, audio (only fullduplex now) with i.e. bristol.
- The firmware has been sniffed from win2k us-428 driver 3.09.
