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. - diff --git a/Documentation/block/deadline-iosched.txt b/Documentation/block/deadline-iosched.txt deleted file mode 100644 index 2b1318600..000000000 --- a/Documentation/block/deadline-iosched.txt +++ /dev/null @@ -1,78 +0,0 @@ -Deadline IO scheduler tunables -============================== - -This little file attempts to document how the deadline io scheduler works. -In particular, it will clarify the meaning of the exposed tunables that may be -of interest to power users. - -Each io queue has a set of io scheduler tunables associated with it.

Here are the file operations that -are available and some comments regarding their behavior: - -open() enables user to open an _existing_ channel.

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.

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). - - -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. - - -Credits -======= - -The ideas and specs for relayfs came about as a result of discussions -on tracing involving the following: - -Michel Dagenais -Richard Moore -Bob Wisniewski -Karim Yaghmour -Tom Zanussi - -Also thanks to Hubertus Franke for a lot of useful suggestions and bug -reports, and for contributing the klog code. diff --git a/Documentation/i2c/i2c-parport b/Documentation/i2c/i2c-parport deleted file mode 100644 index d359461ce..000000000 --- a/Documentation/i2c/i2c-parport +++ /dev/null @@ -1,156 +0,0 @@ -================== -i2c-parport driver -================== - -2004-07-06, Jean Delvare - -This is a unified driver for several i2c-over-parallel-port adapters, -such as the ones made by Philips, Velleman or ELV.

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 ---> - 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.

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.

Overview -=========== -This driver attempts to support the video streaming capabilities of the devices -mounting the SONiX SN9C101 or SONiX SN9C102 PC Camera Controllers. - -- It's worth to note that SONiX has never collaborated with me during the -development of this project, despite of several requests for enough detailed -specifications of the register tables, compression engine and video data format -of the above chips - - -Up to 64 cameras can be handled at the same time. They can be connected and -disconnected from the host many times without turning off the computer, if -your system supports the hotplug facility. - -The driver relies on the Video4Linux2 and USB core modules. It has been -designed to run properly on SMP systems as well. - -The latest version of the SN9C10[12] driver can be found at the following URL: -http://go.lamarinapunto.com/ - - -4. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux and -USB. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, the modules below are -necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -And finally: - - # USB Multimedia devices - # - CONFIG_USB_SN9C102=m - - -5. Module loading -================= -To use the driver, it is necessary to load the "sn9c102" module into memory -after every other module required: "videodev", "usbcore" and, depending on -the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd". - -Loading can be done as shown below: - - [root@localhost home]# modprobe usbcore - [root@localhost home]# modprobe sn9c102 - -At this point the devices should be recognized. You can invoke "dmesg" to -analyze kernel messages and verify that the loading process has gone well: - - [user@localhost home]$ dmesg - - -6. Module parameters -==================== -Module parameters are listed below: -------------------------------------------------------------------------------- -Name: video_nr -Type: int array (min = 0, max = 32) -Syntax: <-1|n[,...]> -Description: Specify V4L2 minor mode number: - -1 = use next available - n = use minor number n - You can specify up to 32 cameras this way. - For example: - video_nr=-1,2,-1 would assign minor number 2 to the second - recognized camera and use auto for the first one and for every - other camera. -Default: -1 -------------------------------------------------------------------------------- -Name: debug -Type: int -Syntax: -Description: Debugging information level, from 0 to 3: - 0 = none (use carefully) - 1 = critical errors - 2 = significant informations - 3 = more verbose messages - Level 3 is useful for testing only, when just one device - is used. -Default: 2 -------------------------------------------------------------------------------- - - -7. Device control through "sysfs" -================================= -It is possible to read and write both the SN9C10[12] and the image sensor -registers by using the "sysfs" filesystem interface. - -Every time a supported device is recognized, read-only files named "redblue" -and "green" are created in the /sys/class/video4linux/videoX directory. You can -set the red, blue and green channel's gain by writing the desired value to -them. The value may range from 0 to 15 for each channel; this means that -"redblue" accepts 8-bit values, where the low 4 bits are reserved for red and -the others for blue. - -There are other four entries in the directory above for each registered camera: -"reg", "val", "i2c_reg" and "i2c_val". The first two files control the -SN9C10[12] bridge, while the other two control the sensor chip. "reg" and -"i2c_reg" hold the values of the current register index where the following -reading/writing operations are addressed at through "val" and "i2c_val". Their -use is not intended for end-users, unless you know what you are doing. Note -that "i2c_reg" and "i2c_val" won't be created if the sensor does not actually -support the standard I2C protocol. Also, remember that you must be logged in as -root before writing to them. - -As an example, suppose we were to want to read the value contained in the -register number 1 of the sensor register table - which usually is the product -identifier - of the camera registered as "/dev/video0": - - [root@localhost #] cd /sys/class/video4linux/video0 - [root@localhost #] echo 1 > i2c_reg - [root@localhost #] cat i2c_val - -Now let's set the green gain's register of the SN9C10[12] chip to 2: - - [root@localhost #] echo 0x11 > reg - [root@localhost #] echo 2 > val - -Note that the SN9C10[12] always returns 0 when some of its registers are read. -To avoid race conditions, all the I/O accesses to the files are serialized. - - -8. Supported devices -==================== -- I won't mention any of the names of the companies as well as their products -here. They have never collaborated with me, so no advertising - - -From the point of view of a driver, what unambiguously identify a device are -its vendor and product USB identifiers. Below is a list of known identifiers of -devices mounting the SN9C10[12] PC camera controllers: - -Vendor ID Product ID ---------- ---------- -0xc45 0x6001 -0xc45 0x6005 -0xc45 0x6009 -0xc45 0x600d -0xc45 0x6024 -0xc45 0x6025 -0xc45 0x6028 -0xc45 0x6029 -0xc45 0x602a -0xc45 0x602c -0xc45 0x8001 - -The list above does NOT imply that all those devices work with this driver: up -until now only the ones that mount the following image sensors are supported. -Kernel messages will always tell you whether this is the case: - -Model Manufacturer ------ ------------ -PAS106B PixArt Imaging Inc. -TAS5110C1B Taiwan Advanced Sensor Corporation -TAS5130D1B Taiwan Advanced Sensor Corporation - -If you think your camera is based on the above hardware and is not actually -listed in the above table, you may try to add the specific USB VendorID and -ProductID identifiers to the sn9c102_id_table[] in the file "sn9c102_sensor.h"; -then compile, load the module again and look at the kernel output. -If this works, please send an email to me reporting the kernel messages, so -that I will add a new entry in the list of supported devices. - -Donations of new models for further testing and support would be much -appreciated. I won't add official support for hardware that I don't actually -have. - - -9. How to add support for new image sensors -=========================================== -It should be easy to write code for new sensors by using the small API that I -have created for this purpose, which is present in "sn9c102_sensor.h" -(documentation is included there). As an example, have a look at the code in -"sn9c102_pas106b.c", which uses the mentioned interface. - -At the moment, not yet supported image sensors are: PAS202B (VGA), -HV7131[D|E1] (VGA), MI03 (VGA), OV7620 (VGA). - - -10. Note for V4L2 developers -============================ -This driver follows the V4L2 API specifications. In particular, it enforces two -rules: - -1) Exactly one I/O method, either "mmap" or "read", is associated with each -file descriptor. Once it is selected, the application must close and reopen the -device to switch to the other I/O method. - -2) Previously mapped buffer memory must always be unmapped before calling any -of the "VIDIOC_S_CROP", "VIDIOC_TRY_FMT" and "VIDIOC_S_FMT" ioctl's. In case, -the same number of buffers as before will be allocated again to match the size -of the new video frames, so you have to map them again before any I/O attempts. - - -11.

The MDIO mode is used to - * communicate with the Quad-PHY from Marvel. The I2C is used to communicate - * with the I2C slave devices. It seems that the driver does not explicitly - * deal with the control of SDA and SCL serial lines. So, the driver will set - * the slave address, drive the command and then the data. The SCMB will then - * control the two serial lines as required. - * - * It seems the documents are very unclear abt this. Hence, I took some time - * out to write the desciption to have an idea of how the I2C can actually - * work. Currently, this Linux driver wont be integrated into the generic Linux - * I2C framework.

Arnold - * - * 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 - * 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. - */ -#define HVCS_DRIVER_VERSION "1.3.0" - -MODULE_AUTHOR("Ryan S.

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).

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.
