-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.
-
-Kernel API
-----------
-
-Here's a summary of the API relayfs provides to in-kernel clients:
-
-int relay_open(channel_path, bufsize, nbufs, channel_flags,
- channel_callbacks, start_reserve, end_reserve,
- rchan_start_reserve, resize_min, resize_max, mode,
- init_buf, init_buf_size)
-int relay_write(channel_id, *data_ptr, count, time_delta_offset, **wrote)
-rchan_reader *add_rchan_reader(channel_id, auto_consume)
-int remove_rchan_reader(rchan_reader *reader)
-rchan_reader *add_map_reader(channel_id)
-int remove_map_reader(rchan_reader *reader)
-int relay_read(reader, buf, count, wait, *actual_read_offset)
-void relay_buffers_consumed(reader, buffers_consumed)
-void relay_bytes_consumed(reader, bytes_consumed, read_offset)
-int relay_bytes_avail(reader)
-int rchan_full(reader)
-int rchan_empty(reader)
-int relay_info(channel_id, *channel_info)
-int relay_close(channel_id)
-int relay_realloc_buffer(channel_id, nbufs, async)
-int relay_replace_buffer(channel_id)
-int relay_reset(int rchan_id)
-
-----------
-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).
-

-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

----------------------------------------------------------------------------
-1. Driver Introduction:
-
-This is the device driver for the IBM Hypervisor Virtual Console Server,
-"hvcs". The IBM hvcs provides a tty driver interface to allow Linux user
-space applications access to the system consoles of logically partitioned
-operating systems (Linux and AIX) running on the same partitioned Power5
-ppc64 system. Physical hardware consoles per partition are not practical
-on this hardware so system consoles are accessed by this driver using
-firmware interfaces to virtual terminal devices.
-
----------------------------------------------------------------------------
-2. System Requirements:
-
-This device driver was written using 2.6.4 Linux kernel APIs and will only
-build and run on kernels of this version or later.
-
-This driver was written to operate solely on IBM Power5 ppc64 hardware
-though some care was taken to abstract the architecture dependent firmware
-calls from the driver code.
-
-Sysfs must be mounted on the system so that the user can determine which
-major and minor numbers are associated with each vty-server. Directions
-for sysfs mounting are outside the scope of this document.
-
----------------------------------------------------------------------------
-3. Build Options:
-
-The hvcs driver registers itself as a tty driver. The tty layer
-dynamically allocates a block of major and minor numbers in a quantity
-requested by the registering driver. The hvcs driver asks the tty layer
-for 64 of these major/minor numbers by default to use for hvcs device node
-entries.
-
-If the default number of device entries is adequate then this driver can be
-built into the kernel. If not, the default can be over-ridden by inserting
-the driver as a module with insmod parameters.
-
----------------------------------------------------------------------------
-3.1 Built-in:
-
-The following menuconfig example demonstrates selecting to build this
-driver into the kernel.
-
- Device Drivers --->
- Character devices --->
- <*> IBM Hypervisor Virtual Console Server Support
-
-Begin the kernel make process.
-
----------------------------------------------------------------------------
-3.2 Module:
-
-The following menuconfig example demonstrates selecting to build this
-driver as a kernel module.
-
- Device Drivers --->
- Character devices --->
- <M> IBM Hypervisor Virtual Console Server Support
-
-The make process will build the following kernel modules:
-
- hvcs.ko
- hvcserver.ko
-
-To insert the module with the default allocation execute the following
-commands in the order they appear:
-
- insmod hvcserver.ko
- insmod hvcs.ko
-
-The hvcserver module contains architecture specific firmware calls and must
-be inserted first, otherwise the hvcs module will not find some of the
-symbols it expects.
-
-To override the default use an insmod parameter as follows (requesting 4
-tty devices as an example):
-
- insmod hvcs.ko hvcs_parm_num_devs=4
-
-There is a maximum number of dev entries that can be specified on insmod.
-We think that 1024 is currently a decent maximum number of server adapters
-to allow. This can always be changed by modifying the constant in the
-source file before building.
-
-NOTE: The length of time it takes to insmod the driver seems to be related
-to the number of tty interfaces the registering driver requests.
-
-In order to remove the driver module execute the following command:
-
- rmmod hvcs.ko
-
-The recommended method for installing hvcs as a module is to use depmod to
-build a current modules.dep file in /lib/modules/`uname -r` and then
-execute:
-
-modprobe hvcs hvcs_parm_num_devs=4
-
-The modules.dep file indicates that hvcserver.ko needs to be inserted
-before hvcs.ko and modprobe uses this file to smartly insert the modules in
-the proper order.
-
-The following modprobe command is used to remove hvcs and hvcserver in the
-proper order:
-
-modprobe -r hvcs
-
----------------------------------------------------------------------------
-4. Installation:
-
-The tty layer creates sysfs entries which contain the major and minor
-numbers allocated for the hvcs driver. The following snippet of "tree"
-output of the sysfs directory shows where these numbers are presented:
-
- sys/
- |-- *other sysfs base dirs*
- |
- |-- class
- | |-- *other classes of devices*
- | |
- | `-- tty
- | |-- *other tty devices*
- | |
- | |-- hvcs0
- | | `-- dev
- | |-- hvcs1
- | | `-- dev
- | |-- hvcs2
- | | `-- dev
- | |-- hvcs3
- | | `-- dev
- | |
- | |-- *other tty devices*
- |
- |-- *other sysfs base dirs*
-
-For the above examples the following output is a result of cat'ing the
-"dev" entry in the hvcs directory:
-
- Pow5:/sys/class/tty/hvcs0/ # cat dev
- 254:0
-
- Pow5:/sys/class/tty/hvcs1/ # cat dev
- 254:1
-
- Pow5:/sys/class/tty/hvcs2/ # cat dev
- 254:2
-
- Pow5:/sys/class/tty/hvcs3/ # cat dev
- 254:3
-
-The output from reading the "dev" attribute is the char device major and
-minor numbers that the tty layer has allocated for this driver's use. Most
-systems running hvcs will already have the device entries created or udev
-will do it automatically.
-
-Given the example output above, to manually create a /dev/hvcs* node entry
-mknod can be used as follows:
-
- mknod /dev/hvcs0 c 254 0
- mknod /dev/hvcs1 c 254 1
- mknod /dev/hvcs2 c 254 2
- mknod /dev/hvcs3 c 254 3
-
-Using mknod to manually create the device entries makes these device nodes
-persistent. Once created they will exist prior to the driver insmod.
-
-Attempting to connect an application to /dev/hvcs* prior to insertion of
-the hvcs module will result in an error message similar to the following:
-
- "/dev/hvcs*: No such device".
-
-NOTE: Just because there is a device node present doesn't mean that there
-is a vty-server device configured for that node.
-
----------------------------------------------------------------------------
-5. Connection
-
-Since this driver controls devices that provide a tty interface a user can
-interact with the device node entries using any standard tty-interactive
-method (e.g. "cat", "dd", "echo"). The intent of this driver however, is
-to provide real time console interaction with a Linux partition's console,
-which requires the use of applications that provide bi-directional,
-interactive I/O with a tty device.
-
-Applications (e.g. "minicom" and "screen") that act as terminal emulators
-or perform terminal type control sequence conversion on the data being
-passed through them are NOT acceptable for providing interactive console
-I/O. These programs often emulate antiquated terminal types (vt100 and
-ANSI) and expect inbound data to take the form of one of these supported
-terminal types but they either do not convert, or do not _adequately_
-convert, outbound data into the terminal type of the terminal which invoked
-them (though screen makes an attempt and can apparently be configured with
-much termcap wrestling.)
-
-For this reason kermit and cu are two of the recommended applications for
-interacting with a Linux console via an hvcs device. These programs simply
-act as a conduit for data transfer to and from the tty device. They do not
-require inbound data to take the form of a particular terminal type, nor do
-they cook outbound data to a particular terminal type.
-
-In order to ensure proper functioning of console applications one must make
-sure that once connected to a /dev/hvcs console that the console's $TERM
-env variable is set to the exact terminal type of the terminal emulator
-used to launch the interactive I/O application. If one is using xterm and
-kermit to connect to /dev/hvcs0 when the console prompt becomes available
-one should "export TERM=xterm" on the console. This tells ncurses
-applications that are invoked from the console that they should output
-control sequences that xterm can understand.
-
-As a precautionary measure an hvcs user should always "exit" from their
-session before disconnecting an application such as kermit from the device
-node. If this is not done, the next user to connect to the console will
-continue using the previous user's logged in session which includes
-using the $TERM variable that the previous user supplied.
-
----------------------------------------------------------------------------
-6. Disconnection
-
-As a security feature to prevent the delivery of stale data to an
-unintended target the Power5 system firmware disables the fetching of data
-and discards that data when a connection between a vty-server and a vty has
-been severed. As an example, when a vty-server is immediately disconnected
-from a vty following output of data to the vty the vty adapter may not have
-enough time between when it received the data interrupt and when the
-connection was severed to fetch the data from firmware before the fetch is
-disabled by firmware.
-
-When hvcs is being used to serve consoles this behavior is not a huge issue
-because the adapter stays connected for large amounts of time following
-almost all data writes. When hvcs is being used as a tty conduit to tunnel
-data between two partitions [see Q & A below] this is a huge problem
-because the standard Linux behavior when cat'ing or dd'ing data to a device
-is to open the tty, send the data, and then close the tty. If this driver
-manually terminated vty-server connections on tty close this would close
-the vty-server and vty connection before the target vty has had a chance to
-fetch the data.
-
-Additionally, disconnecting a vty-server and vty only on module removal or
-adapter removal is impractical because other vty-servers in other
-partitions may require the usage of the target vty at any time.
-
-Due to this behavioral restriction disconnection of vty-servers from the
-connected vty is a manual procedure using a write to a sysfs attribute
-outlined below, on the other hand the initial vty-server connection to a
-vty is established automatically by this driver. Manual vty-server
-connection is never required.
-
-In order to terminate the connection between a vty-server and vty the
-"vterm_state" sysfs attribute within each vty-server's sysfs entry is used.
-Reading this attribute reveals the current connection state of the
-vty-server adapter. A zero means that the vty-server is not connected to a
-vty. A one indicates that a connection is active.
-
-Writing a '0' (zero) to the vterm_state attribute will disconnect the VTERM
-connection between the vty-server and target vty ONLY if the vterm_state
-previously read '1'. The write directive is ignored if the vterm_state
-read '0' or if any value other than '0' was written to the vterm_state
-attribute. The following example will show the method used for verifying
-the vty-server connection status and disconnecting a vty-server connection.
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # cat vterm_state
- 1
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # echo 0 > vterm_state
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # cat vterm_state
- 0
-
-All vty-server connections are automatically terminated when the device is
-hotplug removed and when the module is removed.
-
----------------------------------------------------------------------------
-7. Configuration
-
-Each vty-server has a sysfs entry in the /sys/devices/vio directory, which
-is symlinked in several other sysfs tree directories, notably under the
-hvcs driver entry, which looks like the following example:
-
- Pow5:/sys/bus/vio/drivers/hvcs # ls
- . .. 30000003 30000004 rescan
-
-By design, firmware notifies the hvcs driver of vty-server lifetimes and
-partner vty removals but not the addition of partner vtys. Since an HMC
-Super Admin can add partner info dynamically we have provided the hvcs
-driver sysfs directory with the "rescan" update attribute which will query
-firmware and update the partner info for all the vty-servers that this
-driver manages. Writing a '1' to the attribute triggers the update. An
-explicit example follows:
-
- Pow5:/sys/bus/vio/drivers/hvcs # echo 1 > rescan
-
-Reading the attribute will indicate a state of '1' or '0'. A one indicates
-that an update is in process. A zero indicates that an update has
-completed or was never executed.
-
-Vty-server entries in this directory are a 32 bit partition unique unit
-address that is created by firmware. An example vty-server sysfs entry
-looks like the following:
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # ls
- . current_vty devspec partner_clcs vterm_state
- .. detach_state name partner_vtys
-
-Each entry is provided, by default with a "name" attribute. Reading the
-"name" attribute will reveal the device type as shown in the following
-example:
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000003 # cat name
- vty-server
-
-Each entry is also provided, by default, with a "devspec" attribute which
-reveals the full device specification when read, as shown in the following
-example:
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # cat devspec
- /vdevice/vty-server@30000004
-
-Each vty-server sysfs dir is provided with two read-only attributes that
-provide lists of easily parsed partner vty data: "partner_vtys" and
-"partner_clcs".
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # cat partner_vtys
- 30000000
- 30000001
- 30000002
- 30000000
- 30000000
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # cat partner_clcs
- U5112.428.103048A-V3-C0
- U5112.428.103048A-V3-C2
- U5112.428.103048A-V3-C3
- U5112.428.103048A-V4-C0
- U5112.428.103048A-V5-C0
-
-Reading partner_vtys returns a list of partner vtys. Vty unit address
-numbering is only per-partition-unique so entries will frequently repeat.
-
-Reading partner_clcs returns a list of "converged location codes" which are
-composed of a system serial number followed by "-V*", where the '*' is the
-target partition number, and "-C*", where the '*' is the slot of the
-adapter. The first vty partner corresponds to the first clc item, the
-second vty partner to the second clc item, etc.
-
-A vty-server can only be connected to a single vty at a time. The entry,
-"current_vty" prints the clc of the currently selected partner vty when
-read.
-
-The current_vty can be changed by writing a valid partner clc to the entry
-as in the following example:
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # echo U5112.428.10304
- 8A-V4-C0 > current_vty
-
-Changing the current_vty when a vty-server is already connected to a vty
-does not affect the current connection. The change takes effect when the
-currently open connection is freed.
-
-Information on the "vterm_state" attribute was covered earlier on the
-chapter entitled "disconnection".
-
----------------------------------------------------------------------------
-8. Questions & Answers:
-===========================================================================
-Q: What are the security concerns involving hvcs?
-
-A: There are three main security concerns:
-
- 1. The creator of the /dev/hvcs* nodes has the ability to restrict
- the access of the device entries to certain users or groups. It
- may be best to create a special hvcs group privilege for providing
- access to system consoles.
-
- 2. To provide network security when grabbing the console it is
- suggested that the user connect to the console hosting partition
- using a secure method, such as SSH or sit at a hardware console.
-
- 3. Make sure to exit the user session when done with a console or
- the next vty-server connection (which may be from another
- partition) will experience the previously logged in session.
-
----------------------------------------------------------------------------
-Q: How do I multiplex a console that I grab through hvcs so that other
-people can see it:
-
-A: You can use "screen" to directly connect to the /dev/hvcs* device and
-setup a session on your machine with the console group privileges. As
-pointed out earlier by default screen doesn't provide the termcap settings
-for most terminal emulators to provide adequate character conversion from
-term type "screen" to others. This means that curses based programs may
-not display properly in screen sessions.
-
----------------------------------------------------------------------------
-Q: Why are the colors all messed up?
-Q: Why are the control characters acting strange or not working?
-Q: Why is the console output all strange and unintelligible?
-
-A: Please see the preceding section on "Connection" for a discussion of how
-applications can affect the display of character control sequences.
-Additionally, just because you logged into the console using and xterm
-doesn't mean someone else didn't log into the console with the HMC console
-(vt320) before you and leave the session logged in. The best thing to do
-is to export TERM to the terminal type of your terminal emulator when you
-get the console. Additionally make sure to "exit" the console before you
-disconnect from the console. This will ensure that the next user gets
-their own TERM type set when they login.
-
----------------------------------------------------------------------------
-Q: When I try to CONNECT kermit to an hvcs device I get:
-"Sorry, can't open connection: /dev/hvcs*"What is happening?
-
-A: Some other Power5 console mechanism has a connection to the vty and
-isn't giving it up. You can try to force disconnect the consoles from the
-HMC by right clicking on the partition and then selecting "close terminal".
-Otherwise you have to hunt down the people who have console authority. It
-is possible that you already have the console open using another kermit
-session and just forgot about it. Please review the console options for
-Power5 systems to determine the many ways a system console can be held.
-
-OR
-
-A: Another user may not have a connectivity method currently attached to a
-/dev/hvcs device but the vterm_state may reveal that they still have the
-vty-server connection established. They need to free this using the method
-outlined in the section on "Disconnection" in order for others to connect
-to the target vty.
-
-OR
-
-A: The user profile you are using to execute kermit probably doesn't have
-permissions to use the /dev/hvcs* device.
-
-OR
-
-A: You probably haven't inserted the hvcs.ko module yet but the /dev/hvcs*
-entry still exists (on systems without udev).
-
-OR
-
-A: There is not a corresponding vty-server device that maps to an existing
-/dev/hvcs* entry.
-
----------------------------------------------------------------------------
-Q: When I try to CONNECT kermit to an hvcs device I get:
-"Sorry, write access to UUCP lockfile directory denied."
-
-A: The /dev/hvcs* entry you have specified doesn't exist where you said it
-does? Maybe you haven't inserted the module (on systems with udev).
-
----------------------------------------------------------------------------
-Q: If I already have one Linux partition installed can I use hvcs on said
-partition to provide the console for the install of a second Linux
-partition?
-
-A: Yes granted that your are connected to the /dev/hvcs* device using
-kermit or cu or some other program that doesn't provide terminal emulation.
-
----------------------------------------------------------------------------
-Q: Can I connect to more than one partition's console at a time using this
-driver?
-
-A: Yes. Of course this means that there must be more than one vty-server
-configured for this partition and each must point to a disconnected vty.
-
----------------------------------------------------------------------------
-Q: Does the hvcs driver support dynamic (hotplug) addition of devices?
-
-A: Yes, if you have dlpar and hotplug enabled for your system and it has
-been built into the kernel the hvcs drivers is configured to dynamically
-handle additions of new devices and removals of unused devices.
-
----------------------------------------------------------------------------
-Q: Can I use /dev/hvcs* as a conduit to another partition and use a tty
-device on that partition as the other end of the pipe?
-
-A: Yes, on Power5 platforms the hvc_console driver provides a tty interface
-for extra /dev/hvc* devices (where /dev/hvc0 is most likely the console).
-In order to get a tty conduit working between the two partitions the HMC
-Super Admin must create an additional "serial server" for the target
-partition with the HMC gui which will show up as /dev/hvc* when the target
-partition is rebooted.
-
-The HMC Super Admin then creates an additional "serial client" for the
-current partition and points this at the target partition's newly created
-"serial server" adapter (remember the slot). This shows up as an
-additional /dev/hvcs* device.
-
-Now a program on the target system can be configured to read or write to
-/dev/hvc* and another program on the current partition can be configured to
-read or write to /dev/hvcs*. Now you have a tty conduit between two
-partitions.
-

-9. Reporting Bugs:
-
-The proper channel for reporting bugs is either through the Linux OS
-distribution company that provided your OS or by posting issues to the
-ppc64 development mailing list at:
-
-linuxppc64-dev@lists.linuxppc.org
-
-This request is to provide a documented and searchable public exchange
-of the problems and solutions surrounding this driver for the benefit of
-all users.

-Linux 2.6.x on MPC52xx family
------------------------------
-
-For the latest info, go to http://www.246tNt.com/mpc52xx/state.txt
-
-To compile/use :
-
- - U-Boot:
- # <edit Makefile to set ARCH=ppc & CROSS_COMPILE=... ( also EXTRAVERSION
- if you wish to ).
- # make lite5200_defconfig
- # make uImage
-
- then, on U-boot:
- => tftpboot 200000 uImage
- => tftpboot 400000 pRamdisk
- => bootm 200000 400000
-
- - DBug:
- # <edit Makefile to set ARCH=ppc & CROSS_COMPILE=... ( also EXTRAVERSION
- if you wish to ).
- # make lite5200_defconfig
- # cp your_initrd.gz arch/ppc/boot/images/ramdisk.image.gz
- # make zImage.initrd
- # make
-
- then in DBug:
- DBug> dn -i zImage.initrd.lite5200
-
-
-Some remarks :
- - The port is named mpc52xxx, and config options are PPC_MPC52xx. The MGT5100
- is not supported, and I'm not sure anyone is interesting in working on it
- so. I didn't took 5xxx because there's apparently a lot of 5xxx that have
- nothing to do with the MPC5200. I also included the 'MPC' for the same
- reason.
- - Of course, I inspired myself from the 2.4 port. If you think I forgot to
- mention you/your company in the copyright of some code, I'll correct it
- ASAP.
- - The codes wants the MBAR to be set at 0xf0000000 by the bootloader. It's
- mapped 1:1 with the MMU. If for whatever reason, you want to change this,
- beware that some code depends on the 0xf0000000 address and other depends
- on the 1:1 mapping.
- - Most of the code assumes that port multiplexing, frequency selection, ...
- has already been done. IMHO this should be done as early as possible, in
- the bootloader. If for whatever reason you can't do it there, do it in the
- platform setup code (if U-Boot) or in the arch/ppc/boot/simple/... (if
- DBug)

- * boot-block used to be. It is then up to the protected mode

- * From the IDT errata for the QED RM5230 (Nevada), processor revision 1.0:

- * TLBP
- *
- * The JTLB is being read for the TLBP throughout the stall generated by the
- * previous instruction. This is not really correct as the stalling instruction
- * can modify the address used to access the JTLB. The failure symptom is that
- * the TLBP instruction will use an address created for the stalling instruction
- * and not the address held in C0_ENHI and thus report the wrong results.
- *
- * 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.
- *

- * In general, any use of spinlocks that competes between "base"

- * need to be disabled in the base level routines to avoid it.
- * Or more precisely, only the IRQ the base level routine

- * Each bit is assigned to an interrupt number, where the low register
- * are assigned from IRQ0 to IRQ31 and the high cause register
- * from IRQ32 to IRQ63
- * The GPP (General Purpose Pins) interrupts are assigned from IRQ64 (GPP0)
- * to IRQ95 (GPP31).
- * get_irq() returns the lowest interrupt number that is currently asserted.
- *
- * Note:
- * - This driver does not initialize the GPP when used as an interrupt

- * Interrupt notes:
- * Each sgl descriptor has a copy of the DMA control word which the DMA engine
- * loads in the control register. The control word has a "global" interrupt
- * enable bit for that channel. Interrupts are further qualified by a few bits
- * in the sgl descriptor count register. In order to setup an sgl, we have to
- * know ahead of time whether or not interrupts will be enabled at the completion
- * of the transfers. Thus, enable_dma_interrupt()/disable_dma_interrupt() MUST
- * be called before calling alloc_dma_handle(). If the interrupt mode will never
- * change after powerup, then enable_dma_interrupt()/disable_dma_interrupt()
- * do not have to be called -- interrupts will be enabled or disabled based
- * on how the channel was configured after powerup by the hw_init_dma_channel()
- * function. Each sgl descriptor will be setup to interrupt if an error occurs;
- * however, only the last descriptor will be setup to interrupt. Thus, an
- * interrupt will occur (if interrupts are enabled) only after the complete
- * sgl transfer is done.

- *
- * Author(s) : Ryan S. Arnold <rsa@us.ibm.com>
- *
- * This is the device driver for the IBM Hypervisor Virtual Console Server,
- * "hvcs". The IBM hvcs provides a tty driver interface to allow Linux
- * user space applications access to the system consoles of logically
- * partitioned operating systems, e.g. Linux, running on the same partitioned
- * Power5 ppc64 system. Physical hardware consoles per partition are not
- * practical on this hardware so system consoles are accessed by this driver
- * using inter-partition firmware interfaces to virtual terminal devices.
- *
- * A vty is known to the HMC as a "virtual serial server adapter". It is a
- * virtual terminal device that is created by firmware upon partition creation
- * to act as a partitioned OS's console device.
- *
- * Firmware dynamically (via hotplug) exposes vty-servers to a running ppc64
- * Linux system upon their creation by the HMC or their exposure during boot.
- * The non-user interactive backend of this driver is implemented as a vio
- * device driver so that it can receive notification of vty-server lifetimes
- * after it registers with the vio bus to handle vty-server probe and remove
- * callbacks.
- *
- * Many vty-servers can be configured to connect to one vty, but a vty can
- * only be actively connected to by a single vty-server, in any manner, at one
- * time. If the HMC is currently hosting the console for a target Linux
- * partition; attempts to open the tty device to the partition's console using
- * the hvcs on any partition will return -EBUSY with every open attempt until
- * the HMC frees the connection between its vty-server and the desired
- * partition's vty device. Conversely, a vty-server may only be connected to
- * a single vty at one time even though it may have several configured vty
- * partner possibilities.
- *
- * Firmware does not provide notification of vty partner changes to this
- * driver. This means that an HMC Super Admin may add or remove partner vtys
- * from a vty-server's partner list but the changes will not be signaled to
- * the vty-server. Firmware only notifies the driver when a vty-server is
- * added or removed from the system. To compensate for this deficiency, this
- * driver implements a sysfs update attribute which provides a method for
- * rescanning partner information upon a user's request.
- *
- * Each vty-server, prior to being exposed to this driver is reference counted
- * using the 2.6 Linux kernel kobject construct. This kobject is also used by
- * the vio bus to provide a vio device sysfs entry that this driver attaches
- * device specific attributes to, including partner information. The vio bus
- * framework also provides a sysfs entry for each vio driver. The hvcs driver
- * provides driver attributes in this entry.
- *
- * For direction on installation and usage of this driver please reference
- * Documentation/powerpc/hvcs.txt.

- * 1.0.0 -> 1.1.0 Added kernel_thread scheduling methodology to driver to
- * replace wait_task constructs.
- *
- * 1.1.0 -> 1.2.0 Moved pi_buff initialization out of arch code into driver code
- * and added locking to share this buffer between hvcs_struct instances. This
- * is because the page_size kmalloc can't be done with a spin_lock held.
- *
- * Also added sysfs attribute to manually disconnect the vty-server from the vty
- * due to stupid firmware behavior when opening the connection then sending data
- * then then quickly closing the connection would cause data loss on the
- * receiving side. This required some reordering of the termination code.
- *
- * Fixed the hangup scenario and fixed memory leaks on module_exit.
- *
- * 1.2.0 -> 1.3.0 Moved from manual kernel thread creation & execution to
- * kthread construct which replaced in-kernel IPC for thread termination with
- * kthread_stop and kthread_should_stop. Explicit wait_queue handling was
- * removed because kthread handles this. Minor bug fix to postpone partner_info
- * clearing on hvcs_close until adapter removal to preserve context data for
- * printk on partner connection free. Added lock to protect hvcs_structs so
- * that hvcs_struct instances aren't added or removed during list traversal.
- * Cleaned up comment style, added spaces after commas, and broke function
- * declaration lines to be under 80 columns.

- * 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.
- * Basic support for AG-AND chips is provided.
- *
- * 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)
- *
- * 02-08-2004 tglx: support for strange chips, which cannot auto increment
- * pages on read / read_oob
- *
- * 03-17-2004 tglx: Check ready before auto increment check. Simon Bayes
- * pointed this out, as he marked an auto increment capable chip
- * as NOAUTOINCR in the board driver.
- * Make reads over block boundaries work too
- *
- * 04-14-2004 tglx: first working version for 2k page size chips
- *
- * 05-19-2004 tglx: Basic support for Renesas AG-AND chips
- *
- * Credits:
- * David Woodhouse for adding multichip support
- *
- * Aleph One Ltd. and Toby Churchill Ltd. for supporting the
- * rework for 2K page size chips
- *
- * TODO:
- * Enable cached programming for 2k page size chips
- * Check, if mtd->ecctype should be set to MTD_ECC_HW
- * if we have HW ecc support.
- * The AG-AND chips have nice features for speed improvement,
- * which are not supported yet. Read / program 4 pages in one go.

- *
- * Description:
- *
- * When nand_scan_bbt is called, then it tries to find the bad block table
- * depending on the options in the bbt descriptor(s). If a bbt is found
- * then the contents are read and the memory based bbt is created. If a
- * mirrored bbt is selected then the mirror is searched too and the
- * versions are compared. If the mirror has a greater version number
- * than the mirror bbt is used to build the memory based bbt.
- * If the tables are not versioned, then we "or" the bad block information.
- * If one of the bbt's is out of date or does not exist it is (re)created.
- * If no bbt exists at all then the device is scanned for factory marked
- * good / bad blocks and the bad block tables are created.
- *
- * For manufacturer created bbts like the one found on M-SYS DOC devices
- * the bbt is searched and read but never created
- *
- * The autogenerated bad block table is located in the last good blocks
- * of the device. The table is mirrored, so it can be updated eventually.
- * The table is marked in the oob area with an ident pattern and a version
- * number which indicates which of both tables is more up to date.
- *
- * The table uses 2 bits per block
- * 11b: block is good
- * 00b: block is factory marked bad
- * 01b, 10b: block is marked bad due to wear
- *
- * The memory bad block table uses the following scheme:
- * 00b: block is good
- * 01b: block is marked bad due to wear
- * 10b: block is reserved (to protect the bbt area)
- * 11b: block is factory marked bad
- *
- * Multichip devices like DOC store the bad block info per floor.
- *
- * Following assumptions are made:
- * - bbts start at a page boundary, if autolocated on a block boundary
- * - the space neccecary for a bbt in FLASH does not exceed a block boundary
- *

- * 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.

- *
- * {
- * .vendor = OCP_VENDOR_FREESCALE,
- * .function = OCP_FUNC_PSC_UART,
- * .index = 0,
- * .paddr = MPC52xx_PSC1,

- *
- * This is for PSC1, replace the paddr and irq according to the PSC you want to
- * use. The driver all necessary registers to place the PSC in uart mode without
- * DCD. However, the pin multiplexing aren't changed and should be set either
- * by the bootloader or in the platform init code.
- * The index field must be equal to the PSC index ( e.g. 0 for PSC1, 1 for PSC2,
- * and so on). So the PSC1 is mapped to /dev/ttyS0, PSC2 to /dev/ttyS1 and so
- * on. But be warned, it's an ABSOLUTE REQUIREMENT ! This is needed mainly for
- * the console code : without this 1:1 mapping, at early boot time, when we are
- * parsing the kernel args console=ttyS?, we wouldn't know wich PSC it will be
- * mapped to because OCP stuff is not yet initialized.

- * 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.

-/* 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. */

- * High-speed TUX logging architecture:
- *
- * All fast threads share a common log-ringbuffer. (default size 1MB)
- * Log entries are binary and are padded to be cacheline aligned, this
- * ensures that there is no cache-pingpong between fast threads.
- *
- * The logger thread writes out pending log entries within 1 second
- * (buffer-cache writes data out within 5 seconds). The logger thread
- * gets activated once we have more than 25% of the log ringbuffer
- * filled - or the 1 second log timeout expires. Fast threads block
- * if if more than 95% of the ringbuffer is filled and unblock only
- * if used logbuffer space drops below 90%.
- *
- * This architecture guarantees that 1) logging is reliable (no
- * log entry is ever lost), 2) timely (touches disk within 6 seconds),
- * 3) in the log-contention case the saturation behavior is still
- * write-clustered, but 4) if the logger thread can keep up then
- * the coupling is completely asynchron and parallel.
- *
- * The binary log format gives us about 50% saved IO/memory bandwith
- * and 50% less on-disk used log space than the traditional W3C ASCII
- * format.
- *
- * (We might switch to raw IO though to write the logfile.)
