Despite the +use of tgid, there is no special treatment for the task that is thread group +leader - a process is deemed alive as long as it has any task belonging to it. + +Usage +----- + +To get statistics during a task's lifetime, userspace opens a unicast netlink +socket (NETLINK_GENERIC family) and sends commands specifying a pid or a tgid. +The response contains statistics for a task (if pid is specified) or the sum of +statistics for all tasks of the process (if tgid is specified). + +To obtain statistics for tasks which are exiting, the userspace listener +sends a register command and specifies a cpumask. Whenever a task exits on +one of the cpus in the cpumask, its per-pid statistics are sent to the +registered listener. Using cpumasks allows the data received by one listener +to be limited and assists in flow control over the netlink interface and is +explained in more detail below. + +If the exiting task is the last thread exiting its thread group, +an additional record containing the per-tgid stats is also sent to userspace. +The latter contains the sum of per-pid stats for all threads in the thread +group, both past and present. + +getdelays.c is a simple utility demonstrating usage of the taskstats interface +for reporting delay accounting statistics. Users can register cpumasks, +send commands and process responses, listen for per-tid/tgid exit data, +write the data received to a file and do basic flow control by increasing +receive buffer sizes. + +Interface +--------- + +The user-kernel interface is encapsulated in include/linux/taskstats.h + +To avoid this documentation becoming obsolete as the interface evolves, only +an outline of the current version is given. taskstats.h always overrides the +description here. + +struct taskstats is the common accounting structure for both per-pid and +per-tgid data. It is versioned and can be extended by each accounting subsystem +that is added to the kernel. The fields and their semantics are defined in the +taskstats.h file. + +The data exchanged between user and kernel space is a netlink message belonging +to the NETLINK_GENERIC family and using the netlink attributes interface. +The messages are in the format + + +----------+- - -+-------------+-------------------+ + | nlmsghdr | Pad | genlmsghdr | taskstats payload | + +----------+- - -+-------------+-------------------+ + + +The taskstats payload is one of the following three kinds: + +1. Commands: Sent from user to kernel. Commands to get data on +a pid/tgid consist of one attribute, of type TASKSTATS_CMD_ATTR_PID/TGID, +containing a u32 pid or tgid in the attribute payload. The pid/tgid denotes +the task/process for which userspace wants statistics. + +Commands to register/deregister interest in exit data from a set of cpus +consist of one attribute, of type +TASKSTATS_CMD_ATTR_REGISTER/DEREGISTER_CPUMASK and contain a cpumask in the +attribute payload. The cpumask is specified as an ascii string of +comma-separated cpu ranges e.g. to listen to exit data from cpus 1,2,3,5,7,8 +the cpumask would be "1-3,5,7-8". If userspace forgets to deregister interest +in cpus before closing the listening socket, the kernel cleans up its interest +set over time. However, for the sake of efficiency, an explicit deregistration +is advisable. + +2. Response for a command: sent from the kernel in response to a userspace +command. The payload is a series of three attributes of type: + +a) TASKSTATS_TYPE_AGGR_PID/TGID : attribute containing no payload but indicates +a pid/tgid will be followed by some stats. + +b) TASKSTATS_TYPE_PID/TGID: attribute whose payload is the pid/tgid whose stats +is being returned. + +c) TASKSTATS_TYPE_STATS: attribute with a struct taskstsats as payload. The +same structure is used for both per-pid and per-tgid stats. + +3. New message sent by kernel whenever a task exits. The payload consists of a + series of attributes of the following type: + +a) TASKSTATS_TYPE_AGGR_PID: indicates next two attributes will be pid+stats +b) TASKSTATS_TYPE_PID: contains exiting task's pid +c) TASKSTATS_TYPE_STATS: contains the exiting task's per-pid stats +d) TASKSTATS_TYPE_AGGR_TGID: indicates next two attributes will be tgid+stats +e) TASKSTATS_TYPE_TGID: contains tgid of process to which task belongs +f) TASKSTATS_TYPE_STATS: contains the per-tgid stats for exiting task's process + + +per-tgid stats +-------------- + +Taskstats provides per-process stats, in addition to per-task stats, since +resource management is often done at a process granularity and aggregating task +stats in userspace alone is inefficient and potentially inaccurate (due to lack +of atomicity). + +However, maintaining per-process, in addition to per-task stats, within the +kernel has space and time overheads. To address this, the taskstats code +accumalates each exiting task's statistics into a process-wide data structure. +When the last task of a process exits, the process level data accumalated also +gets sent to userspace (along with the per-task data). + +When a user queries to get per-tgid data, the sum of all other live threads in +the group is added up and added to the accumalated total for previously exited +threads of the same thread group. + +Extending taskstats +------------------- + +There are two ways to extend the taskstats interface to export more +per-task/process stats as patches to collect them get added to the kernel +in future: + +1. Adding more fields to the end of the existing struct taskstats. Backward + compatibility is ensured by the version number within the + structure. Userspace will use only the fields of the struct that correspond + to the version its using. + +2. Defining separate statistic structs and using the netlink attributes + interface to return them. Since userspace processes each netlink attribute + independently, it can always ignore attributes whose type it does not + understand (because it is using an older version of the interface). + + +Choosing between 1. and 2. is a matter of trading off flexibility and +overhead. If only a few fields need to be added, then 1. is the preferable +path since the kernel and userspace don't need to incur the overhead of +processing new netlink attributes. But if the new fields expand the existing +struct too much, requiring disparate userspace accounting utilities to +unnecessarily receive large structures whose fields are of no interest, then +extending the attributes structure would be worthwhile. + +Flow control for taskstats +-------------------------- + +When the rate of task exits becomes large, a listener may not be able to keep +up with the kernel's rate of sending per-tid/tgid exit data leading to data +loss. This possibility gets compounded when the taskstats structure gets +extended and the number of cpus grows large. + +To avoid losing statistics, userspace should do one or more of the following: + +- increase the receive buffer sizes for the netlink sockets opened by +listeners to receive exit data. + +- create more listeners and reduce the number of cpus being listened to by +each listener. In the extreme case, there could be one listener for each cpu. +Users may also consider setting the cpu affinity of the listener to the subset +of cpus to which it listens, especially if they are listening to just one cpu. + +Despite these measures, if the userspace receives ENOBUFS error messages +indicated overflow of receive buffers, it should take measures to handle the +loss of data. + +---- diff --git a/Documentation/cciss.txt b/Documentation/cciss.txt index 15378422fc46..9c629ffa0e58 100644 --- a/Documentation/cciss.txt +++ b/Documentation/cciss.txt @@ -20,6 +20,7 @@ This driver is known to work with the following cards: * SA P400i * SA E200 * SA E200i + * SA E500 If nodes are not already created in the /dev/cciss directory, run as root: diff --git a/Documentation/connector/ucon.c b/Documentation/connector/ucon.c new file mode 100644 index 000000000000..d738cde2a8d5 --- /dev/null +++ b/Documentation/connector/ucon.c @@ -0,0 +1,206 @@ +/* + * ucon.c + * + * Copyright (c) 2004+ Evgeniy Polyakov + * + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The relay files +themselves are files created in a host filesystem, e.g. debugfs, and +are associated with the channel buffers using the API described below. + +The format of the data logged into the channel buffers is completely +up to the kernel client; the relay interface does however provide +hooks which allow kernel clients to impose some structure on the +buffer data. The relay interface doesn't implement any form of data +filtering - this also is left to the kernel client. The purpose is to +keep things as simple as possible. + +This document provides an overview of the relay interface API. The +details of the function parameters are documented along with the +functions in the relay interface code - please see that for details. + +Semantics +========= + +Each relay channel has one buffer per CPU, each buffer has one or more +sub-buffers. Messages are written to the first sub-buffer until it is +too full to contain a new message, in which case it it is written to +the next (if available). Messages are never split across sub-buffers. +At this point, userspace can be notified so it empties the first +sub-buffer, while the kernel continues writing to the next. + +When notified that a sub-buffer is full, the kernel knows how many +bytes of it are padding i.e. unused space occurring because a complete +message couldn't fit into a sub-buffer. Userspace can use this +knowledge to copy only valid data. + +After copying it, userspace can notify the kernel that a sub-buffer +has been consumed. + +A relay channel can operate in a mode where it will overwrite data not +yet collected by userspace, and not wait for it to be consumed. + +The relay channel itself does not provide for communication of such +data between userspace and kernel, allowing the kernel side to remain +simple and not impose a single interface on userspace. It does +provide a set of examples and a separate helper though, described +below. + +The read() interface both removes padding and internally consumes the +read sub-buffers; thus in cases where read(2) is being used to drain +the channel buffers, special-purpose communication between kernel and +user isn't necessary for basic operation. + +One of the major goals of the relay interface is to provide a low +overhead mechanism for conveying kernel data to userspace. While the +read() interface is easy to use, it's not as efficient as the mmap() +approach; the example code attempts to make the tradeoff between the +two approaches as small as possible. + +klog and relay-apps example code +================================ + +The relay interface itself is ready to use, but to make things easier, +a couple simple utility functions and a set of examples are provided. + +The relay-apps example tarball, available on the relay sourceforge +site, contains a set of self-contained examples, each consisting of a +pair of .c files containing boilerplate code for each of the user and +kernel sides of a relay application. When combined these two sets of +boilerplate code provide glue to easily stream data to disk, without +having to bother with mundane housekeeping chores. + +The 'klog debugging functions' patch (klog.patch in the relay-apps +tarball) provides a couple of high-level logging functions to the +kernel which allow writing formatted text or raw data to a channel, +regardless of whether a channel to write into exists or not, or even +whether the relay interface is compiled into the kernel or not. These +functions allow you to put unconditional 'trace' statements anywhere +in the kernel or kernel modules; only when there is a 'klog handler' +registered will data actually be logged (see the klog and kleak +examples for details). + +It is of course possible to use the relay interface from scratch, +i.e. without using any of the relay-apps example code or klog, but +you'll have to implement communication between userspace and kernel, +allowing both to convey the state of buffers (full, empty, amount of +padding). The read() interface both removes padding and internally +consumes the read sub-buffers; thus in cases where read(2) is being +used to drain the channel buffers, special-purpose communication +between kernel and user isn't necessary for basic operation. Things +such as buffer-full conditions would still need to be communicated via +some channel though. + +klog and the relay-apps examples can be found in the relay-apps +tarball on http://relayfs.sourceforge.net + +The relay interface user space API +================================== + +The relay interface implements basic file operations for user space +access to relay channel buffer data. Here are the file operations +that are available and some comments regarding their behavior: + +open() enables user to open an _existing_ channel buffer. + +mmap() results in channel buffer being mapped into the caller's + memory space. Note that you can't do a partial mmap - you + must map the entire file, which is NRBUF * SUBBUFSIZE. + +read() read the contents of a channel buffer. The bytes read are + 'consumed' by the reader, i.e. they won't be available + again to subsequent reads. If the channel is being used + in no-overwrite mode (the default), it can be read at any + time even if there's an active kernel writer. If the + channel is being used in overwrite mode and there are + active channel writers, results may be unpredictable - + users should make sure that all logging to the channel has + ended before using read() with overwrite mode. Sub-buffer + padding is automatically removed and will not be seen by + the reader. + +sendfile() transfer data from a channel buffer to an output file + descriptor. Sub-buffer padding is automatically removed + and will not be seen by the reader. + +poll() POLLIN/POLLRDNORM/POLLERR supported. User applications are + notified when sub-buffer boundaries are crossed. + +close() decrements the channel buffer's refcount. When the refcount + reaches 0, i.e. when no process or kernel client has the + buffer open, the channel buffer is freed. + +In order for a user application to make use of relay files, the +host filesystem must be mounted. For example, + + mount -t debugfs debugfs /debug + +NOTE: the host filesystem doesn't need to be mounted for kernel + clients to create or use channels - it only needs to be + mounted when user space applications need access to the buffer + data. + + +The relay interface kernel API +============================== + +Here's a summary of the API the relay interface provides to in-kernel clients: + +TBD(curr. line MT:/API/) + channel management functions: + + relay_open(base_filename, parent, subbuf_size, n_subbufs, + callbacks) + relay_close(chan) + relay_flush(chan) + relay_reset(chan) + + channel management typically called on instigation of userspace: + + relay_subbufs_consumed(chan, cpu, subbufs_consumed) + + write functions: + + relay_write(chan, data, length) + __relay_write(chan, data, length) + relay_reserve(chan, length) + + callbacks: + + subbuf_start(buf, subbuf, prev_subbuf, prev_padding) + buf_mapped(buf, filp) + buf_unmapped(buf, filp) + create_buf_file(filename, parent, mode, buf, is_global) + remove_buf_file(dentry) + + helper functions: + + relay_buf_full(buf) + subbuf_start_reserve(buf, length) + + +Creating a channel +------------------ + +relay_open() is used to create a channel, along with its per-cpu +channel buffers. Each channel buffer will have an associated file +created for it in the host filesystem, which can be and mmapped or +read from in user space. The files are named basename0...basenameN-1 +where N is the number of online cpus, and by default will be created +in the root of the filesystem (if the parent param is NULL). If you +want a directory structure to contain your relay files, you should +create it using the host filesystem's directory creation function, +e.g. debugfs_create_dir(), and pass the parent directory to +relay_open(). Users are responsible for cleaning up any directory +structure they create, when the channel is closed - again the host +filesystem's directory removal functions should be used for that, +e.g. debugfs_remove(). + +In order for a channel to be created and the host filesystem's files +associated with its channel buffers, the user must provide definitions +for two callback functions, create_buf_file() and remove_buf_file(). +create_buf_file() is called once for each per-cpu buffer from +relay_open() and allows the user to create the file which will be used +to represent the corresponding channel buffer. The callback should +return the dentry of the file created to represent the channel buffer. +remove_buf_file() must also be defined; it's responsible for deleting +the file(s) created in create_buf_file() and is called during +relay_close(). + +Here are some typical definitions for these callbacks, in this case +using debugfs: + +/* + * create_buf_file() callback. Creates relay file in debugfs. + */ +static struct dentry *create_buf_file_handler(const char *filename, + struct dentry *parent, + int mode, + struct rchan_buf *buf, + int *is_global) +{ + return debugfs_create_file(filename, mode, parent, buf, + &relay_file_operations); +} + +/* + * remove_buf_file() callback. Removes relay file from debugfs. + */ +static int remove_buf_file_handler(struct dentry *dentry) +{ + debugfs_remove(dentry); + + return 0; +} + +/* + * relay interface callbacks + */ +static struct rchan_callbacks relay_callbacks = +{ + .create_buf_file = create_buf_file_handler, + .remove_buf_file = remove_buf_file_handler, +}; + +And an example relay_open() invocation using them: + + chan = relay_open("cpu", NULL, SUBBUF_SIZE, N_SUBBUFS, &relay_callbacks); + +If the create_buf_file() callback fails, or isn't defined, channel +creation and thus relay_open() will fail. + +The total size of each per-cpu buffer is calculated by multiplying the +number of sub-buffers by the sub-buffer size passed into relay_open(). +The idea behind sub-buffers is that they're basically an extension of +double-buffering to N buffers, and they also allow applications to +easily implement random-access-on-buffer-boundary schemes, which can +be important for some high-volume applications. The number and size +of sub-buffers is completely dependent on the application and even for +the same application, different conditions will warrant different +values for these parameters at different times. Typically, the right +values to use are best decided after some experimentation; in general, +though, it's safe to assume that having only 1 sub-buffer is a bad +idea - you're guaranteed to either overwrite data or lose events +depending on the channel mode being used. + +The create_buf_file() implementation can also be defined in such a way +as to allow the creation of a single 'global' buffer instead of the +default per-cpu set. This can be useful for applications interested +mainly in seeing the relative ordering of system-wide events without +the need to bother with saving explicit timestamps for the purpose of +merging/sorting per-cpu files in a postprocessing step. + +To have relay_open() create a global buffer, the create_buf_file() +implementation should set the value of the is_global outparam to a +non-zero value in addition to creating the file that will be used to +represent the single buffer. In the case of a global buffer, +create_buf_file() and remove_buf_file() will be called only once. The +normal channel-writing functions, e.g. relay_write(), can still be +used - writes from any cpu will transparently end up in the global +buffer - but since it is a global buffer, callers should make sure +they use the proper locking for such a buffer, either by wrapping +writes in a spinlock, or by copying a write function from relay.h and +creating a local version that internally does the proper locking. + +Channel 'modes' +--------------- + +relay channels can be used in either of two modes - 'overwrite' or +'no-overwrite'. The mode is entirely determined by the implementation +of the subbuf_start() callback, as described below. The default if no +subbuf_start() callback is defined is 'no-overwrite' mode. If the +default mode suits your needs, and you plan to use the read() +interface to retrieve channel data, you can ignore the details of this +section, as it pertains mainly to mmap() implementations. + +In 'overwrite' mode, also known as 'flight recorder' mode, writes +continuously cycle around the buffer and will never fail, but will +unconditionally overwrite old data regardless of whether it's actually +been consumed. In no-overwrite mode, writes will fail, i.e. data will +be lost, if the number of unconsumed sub-buffers equals the total +number of sub-buffers in the channel. It should be clear that if +there is no consumer or if the consumer can't consume sub-buffers fast +enough, data will be lost in either case; the only difference is +whether data is lost from the beginning or the end of a buffer. + +As explained above, a relay channel is made of up one or more +per-cpu channel buffers, each implemented as a circular buffer +subdivided into one or more sub-buffers. Messages are written into +the current sub-buffer of the channel's current per-cpu buffer via the +write functions described below. Whenever a message can't fit into +the current sub-buffer, because there's no room left for it, the +client is notified via the subbuf_start() callback that a switch to a +new sub-buffer is about to occur. The client uses this callback to 1) +initialize the next sub-buffer if appropriate 2) finalize the previous +sub-buffer if appropriate and 3) return a boolean value indicating +whether or not to actually move on to the next sub-buffer. + +To implement 'no-overwrite' mode, the userspace client would provide +an implementation of the subbuf_start() callback something like the +following: + +static int subbuf_start(struct rchan_buf *buf, + void *subbuf, + void *prev_subbuf, + unsigned int prev_padding) +{ + if (prev_subbuf) + *((unsigned *)prev_subbuf) = prev_padding; + + if (relay_buf_full(buf)) + return 0; + + subbuf_start_reserve(buf, sizeof(unsigned int)); + + return 1; +} + +If the current buffer is full, i.e. all sub-buffers remain unconsumed, +the callback returns 0 to indicate that the buffer switch should not +occur yet, i.e. until the consumer has had a chance to read the +current set of ready sub-buffers. For the relay_buf_full() function +to make sense, the consumer is reponsible for notifying the relay +interface when sub-buffers have been consumed via +relay_subbufs_consumed(). Any subsequent attempts to write into the +buffer will again invoke the subbuf_start() callback with the same +parameters; only when the consumer has consumed one or more of the +ready sub-buffers will relay_buf_full() return 0, in which case the +buffer switch can continue. + +The implementation of the subbuf_start() callback for 'overwrite' mode +would be very similar: + +static int subbuf_start(struct rchan_buf *buf, + void *subbuf, + void *prev_subbuf, + unsigned int prev_padding) +{ + if (prev_subbuf) + *((unsigned *)prev_subbuf) = prev_padding; + + subbuf_start_reserve(buf, sizeof(unsigned int)); + + return 1; +} + +In this case, the relay_buf_full() check is meaningless and the +callback always returns 1, causing the buffer switch to occur +unconditionally. It's also meaningless for the client to use the +relay_subbufs_consumed() function in this mode, as it's never +consulted. + +The default subbuf_start() implementation, used if the client doesn't +define any callbacks, or doesn't define the subbuf_start() callback, +implements the simplest possible 'no-overwrite' mode, i.e. it does +nothing but return 0. + +Header information can be reserved at the beginning of each sub-buffer +by calling the subbuf_start_reserve() helper function from within the +subbuf_start() callback. This reserved area can be used to store +whatever information the client wants. In the example above, room is +reserved in each sub-buffer to store the padding count for that +sub-buffer. This is filled in for the previous sub-buffer in the +subbuf_start() implementation; the padding value for the previous +sub-buffer is passed into the subbuf_start() callback along with a +pointer to the previous sub-buffer, since the padding value isn't +known until a sub-buffer is filled. The subbuf_start() callback is +also called for the first sub-buffer when the channel is opened, to +give the client a chance to reserve space in it. In this case the +previous sub-buffer pointer passed into the callback will be NULL, so +the client should check the value of the prev_subbuf pointer before +writing into the previous sub-buffer. + +Writing to a channel +-------------------- + +Kernel clients write data into the current cpu's channel buffer using +relay_write() or __relay_write(). relay_write() is the main logging +function - it uses local_irqsave() to protect the buffer and should be +used if you might be logging from interrupt context. If you know +you'll never be logging from interrupt context, you can use +__relay_write(), which only disables preemption. These functions +don't return a value, so you can't determine whether or not they +failed - the assumption is that you wouldn't want to check a return +value in the fast logging path anyway, and that they'll always succeed +unless the buffer is full and no-overwrite mode is being used, in +which case you can detect a failed write in the subbuf_start() +callback by calling the relay_buf_full() helper function. + +relay_reserve() is used to reserve a slot in a channel buffer which +can be written to later. This would typically be used in applications +that need to write directly into a channel buffer without having to +stage data in a temporary buffer beforehand. Because the actual write +may not happen immediately after the slot is reserved, applications +using relay_reserve() can keep a count of the number of bytes actually +written, either in space reserved in the sub-buffers themselves or as +a separate array. See the 'reserve' example in the relay-apps tarball +at http://relayfs.sourceforge.net for an example of how this can be +done. Because the write is under control of the client and is +separated from the reserve, relay_reserve() doesn't protect the buffer +at all - it's up to the client to provide the appropriate +synchronization when using relay_reserve(). + +Closing a channel +----------------- + +The client calls relay_close() when it's finished using the channel. +The channel and its associated buffers are destroyed when there are no +longer any references to any of the channel buffers. relay_flush() +forces a sub-buffer switch on all the channel buffers, and can be used +to finalize and process the last sub-buffers before the channel is +closed. + +Misc +---- + +Some applications may want to keep a channel around and re-use it +rather than open and close a new channel for each use. relay_reset() +can be used for this purpose - it resets a channel to its initial +state without reallocating channel buffer memory or destroying +existing mappings. It should however only be called when it's safe to +do so, i.e. when the channel isn't currently being written to. + +Finally, there are a couple of utility callbacks that can be used for +different purposes. buf_mapped() is called whenever a channel buffer +is mmapped from user space and buf_unmapped() is called when it's +unmapped. The client can use this notification to trigger actions +within the kernel application, such as enabling/disabling logging to +the channel. + + +Resources +========= + +For news, example code, mailing list, etc. see the relay interface homepage: + + http://relayfs.sourceforge.net + + +Credits +======= + +The ideas and specs for the relay interface 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. diff --git a/Documentation/filesystems/relayfs.txt b/Documentation/filesystems/relayfs.txt deleted file mode 100644 index 5832377b7340..000000000000 --- a/Documentation/filesystems/relayfs.txt +++ /dev/null @@ -1,442 +0,0 @@ - -relayfs - a high-speed data relay filesystem -============================================ - -relayfs is a filesystem designed to provide an efficient mechanism for -tools and facilities to relay large and potentially sustained streams -of data from kernel space to user space. - -The main abstraction of relayfs is the 'channel'.

In this case the -previous sub-buffer pointer passed into the callback will be NULL, so -the client should check the value of the prev_subbuf pointer before -writing into the previous sub-buffer. - -Writing to a channel --------------------- - -kernel clients write data into the current cpu's channel buffer using -relay_write() or __relay_write(). relay_write() is the main logging -function - it uses local_irqsave() to protect the buffer and should be -used if you might be logging from interrupt context. If you know -you'll never be logging from interrupt context, you can use -__relay_write(), which only disables preemption. These functions -don't return a value, so you can't determine whether or not they -failed - the assumption is that you wouldn't want to check a return -value in the fast logging path anyway, and that they'll always succeed -unless the buffer is full and no-overwrite mode is being used, in -which case you can detect a failed write in the subbuf_start() -callback by calling the relay_buf_full() helper function. - -relay_reserve() is used to reserve a slot in a channel buffer which -can be written to later. This would typically be used in applications -that need to write directly into a channel buffer without having to -stage data in a temporary buffer beforehand. Because the actual write -may not happen immediately after the slot is reserved, applications -using relay_reserve() can keep a count of the number of bytes actually -written, either in space reserved in the sub-buffers themselves or as -a separate array. See the 'reserve' example in the relay-apps tarball -at http://relayfs.sourceforge.net for an example of how this can be -done. Because the write is under control of the client and is -separated from the reserve, relay_reserve() doesn't protect the buffer -at all - it's up to the client to provide the appropriate -synchronization when using relay_reserve(). - -Closing a channel ------------------ - -The client calls relay_close() when it's finished using the channel. -The channel and its associated buffers are destroyed when there are no -longer any references to any of the channel buffers. relay_flush() -forces a sub-buffer switch on all the channel buffers, and can be used -to finalize and process the last sub-buffers before the channel is -closed. - -Creating non-relay files ------------------------- - -relay_open() automatically creates files in the relayfs filesystem to -represent the per-cpu kernel buffers; it's often useful for -applications to be able to create their own files alongside the relay -files in the relayfs filesystem as well e.g. 'control' files much like -those created in /proc or debugfs for similar purposes, used to -communicate control information between the kernel and user sides of a -relayfs application. For this purpose the relayfs_create_file() and -relayfs_remove_file() API functions exist. For relayfs_create_file(), -the caller passes in a set of user-defined file operations to be used -for the file and an optional void * to a user-specified data item, -which will be accessible via inode->u.generic_ip (see the relay-apps -tarball for examples). The file_operations are a required parameter -to relayfs_create_file() and thus the semantics of these files are -completely defined by the caller. - -See the relay-apps tarball at http://relayfs.sourceforge.net for -examples of how these non-relay files are meant to be used. - -Creating relay files in other filesystems ------------------------------------------ - -By default of course, relay_open() creates relay files in the relayfs -filesystem. Because relay_file_operations is exported, however, it's -also possible to create and use relay files in other pseudo-filesytems -such as debugfs. - -For this purpose, two callback functions are provided, -create_buf_file() and remove_buf_file(). create_buf_file() is called -once for each per-cpu buffer from relay_open() to allow the client to -create a file to be used to represent the corresponding buffer; if -this callback is not defined, the default implementation will create -and return a file in the relayfs filesystem to represent the buffer. -The callback should return the dentry of the file created to represent -the relay buffer. Note that the parent directory passed to -relay_open() (and passed along to the callback), if specified, must -exist in the same filesystem the new relay file is created in. If -create_buf_file() is defined, remove_buf_file() must also be defined; -it's responsible for deleting the file(s) created in create_buf_file() -and is called during relay_close(). - -The create_buf_file() implementation can also be defined in such a way -as to allow the creation of a single 'global' buffer instead of the -default per-cpu set. This can be useful for applications interested -mainly in seeing the relative ordering of system-wide events without -the need to bother with saving explicit timestamps for the purpose of -merging/sorting per-cpu files in a postprocessing step. - -To have relay_open() create a global buffer, the create_buf_file() -implementation should set the value of the is_global outparam to a -non-zero value in addition to creating the file that will be used to -represent the single buffer. In the case of a global buffer, -create_buf_file() and remove_buf_file() will be called only once. The -normal channel-writing functions e.g. relay_write() can still be used -- writes from any cpu will transparently end up in the global buffer - -but since it is a global buffer, callers should make sure they use the -proper locking for such a buffer, either by wrapping writes in a -spinlock, or by copying a write function from relayfs_fs.h and -creating a local version that internally does the proper locking. - -See the 'exported-relayfile' examples in the relay-apps tarball for -examples of creating and using relay files in debugfs. - -Misc ----- - -Some applications may want to keep a channel around and re-use it -rather than open and close a new channel for each use. relay_reset() -can be used for this purpose - it resets a channel to its initial -state without reallocating channel buffer memory or destroying -existing mappings. It should however only be called when it's safe to -do so i.e. when the channel isn't currently being written to. - -Finally, there are a couple of utility callbacks that can be used for -different purposes. buf_mapped() is called whenever a channel buffer -is mmapped from user space and buf_unmapped() is called when it's -unmapped. The client can use this notification to trigger actions -within the kernel application, such as enabling/disabling logging to -the channel. - - -Resources -========= - -For news, example code, mailing list, etc. see the relayfs homepage: - - http://relayfs.sourceforge.net - - -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. diff --git a/Documentation/filesystems/vfs.txt b/Documentation/filesystems/vfs.txt index 9d3aed628bc1..1cb7e8be927a 100644 --- a/Documentation/filesystems/vfs.txt +++ b/Documentation/filesystems/vfs.txt @@ -113,8 +113,8 @@ members are defined: struct file_system_type { const char *name; int fs_flags; - struct int (*get_sb) (struct file_system_type *, int, - const char *, void *, struct vfsmount *); + int (*get_sb) (struct file_system_type *, int, + const char *, void *, struct vfsmount *); void (*kill_sb) (struct super_block *); struct module *owner; struct file_system_type * next; diff --git a/Documentation/hwmon/abituguru b/Documentation/hwmon/abituguru index 69cdb527d58f..b2c0d61b39a2 100644 --- a/Documentation/hwmon/abituguru +++ b/Documentation/hwmon/abituguru @@ -2,13 +2,36 @@ Kernel driver abituguru ======================= Supported chips: - * Abit uGuru (Hardware Monitor part only) + * Abit uGuru revision 1-3 (Hardware Monitor part only) Prefix: 'abituguru' Addresses scanned: ISA 0x0E0 Datasheet: Not available, this driver is based on reverse engineering.

The +following states are exclusive, and only one of them is allowed to be +set for any lock-class: + + and + and + +The validator detects and reports lock usage that violate these +single-lock state rules. + +Multi-lock dependency rules: +---------------------------- + +The same lock-class must not be acquired twice, because this could lead +to lock recursion deadlocks. + +Furthermore, two locks may not be taken in different order: + + -> + -> + +because this could lead to lock inversion deadlocks. (The validator +finds such dependencies in arbitrary complexity, i.e. there can be any +other locking sequence between the acquire-lock operations, the +validator will still track all dependencies between locks.) + +Furthermore, the following usage based lock dependencies are not allowed +between any two lock-classes: + + -> + -> + +The first rule comes from the fact the a hardirq-safe lock could be +taken by a hardirq context, interrupting a hardirq-unsafe lock - and +thus could result in a lock inversion deadlock. Likewise, a softirq-safe +lock could be taken by an softirq context, interrupting a softirq-unsafe +lock. + +The above rules are enforced for any locking sequence that occurs in the +kernel: when acquiring a new lock, the validator checks whether there is +any rule violation between the new lock and any of the held locks. + +When a lock-class changes its state, the following aspects of the above +dependency rules are enforced: + +- if a new hardirq-safe lock is discovered, we check whether it + took any hardirq-unsafe lock in the past. + +- if a new softirq-safe lock is discovered, we check whether it took + any softirq-unsafe lock in the past. + +- if a new hardirq-unsafe lock is discovered, we check whether any + hardirq-safe lock took it in the past. + +- if a new softirq-unsafe lock is discovered, we check whether any + softirq-safe lock took it in the past. + +(Again, we do these checks too on the basis that an interrupt context +could interrupt _any_ of the irq-unsafe or hardirq-unsafe locks, which +could lead to a lock inversion deadlock - even if that lock scenario did +not trigger in practice yet.) + +Exception: Nested data dependencies leading to nested locking +------------------------------------------------------------- + +There are a few cases where the Linux kernel acquires more than one +instance of the same lock-class. Such cases typically happen when there +is some sort of hierarchy within objects of the same type. In these +cases there is an inherent "natural" ordering between the two objects +(defined by the properties of the hierarchy), and the kernel grabs the +locks in this fixed order on each of the objects. + +An example of such an object hieararchy that results in "nested locking" +is that of a "whole disk" block-dev object and a "partition" block-dev +object; the partition is "part of" the whole device and as long as one +always takes the whole disk lock as a higher lock than the partition +lock, the lock ordering is fully correct. The validator does not +automatically detect this natural ordering, as the locking rule behind +the ordering is not static. + +In order to teach the validator about this correct usage model, new +versions of the various locking primitives were added that allow you to +specify a "nesting level". An example call, for the block device mutex, +looks like this: + +enum bdev_bd_mutex_lock_class +{ + BD_MUTEX_NORMAL, + BD_MUTEX_WHOLE, + BD_MUTEX_PARTITION +}; + + mutex_lock_nested(&bdev->bd_contains->bd_mutex, BD_MUTEX_PARTITION); + +In this case the locking is done on a bdev object that is known to be a +partition. + +The validator treats a lock that is taken in such a nested fasion as a +separate (sub)class for the purposes of validation. + +Note: When changing code to use the _nested() primitives, be careful and +check really thoroughly that the hiearchy is correctly mapped; otherwise +you can get false positives or false negatives. + +Proof of 100% correctness: +-------------------------- + +The validator achieves perfect, mathematical 'closure' (proof of locking +correctness) in the sense that for every simple, standalone single-task +locking sequence that occured at least once during the lifetime of the +kernel, the validator proves it with a 100% certainty that no +combination and timing of these locking sequences can cause any class of +lock related deadlock. [*] + +I.e. complex multi-CPU and multi-task locking scenarios do not have to +occur in practice to prove a deadlock: only the simple 'component' +locking chains have to occur at least once (anytime, in any +task/context) for the validator to be able to prove correctness. (For +example, complex deadlocks that would normally need more than 3 CPUs and +a very unlikely constellation of tasks, irq-contexts and timings to +occur, can be detected on a plain, lightly loaded single-CPU system as +well!) + +This radically decreases the complexity of locking related QA of the +kernel: what has to be done during QA is to trigger as many "simple" +single-task locking dependencies in the kernel as possible, at least +once, to prove locking correctness - instead of having to trigger every +possible combination of locking interaction between CPUs, combined with +every possible hardirq and softirq nesting scenario (which is impossible +to do in practice). + +[*] assuming that the validator itself is 100% correct, and no other + part of the system corrupts the state of the validator in any way. + We also assume that all NMI/SMM paths [which could interrupt + even hardirq-disabled codepaths] are correct and do not interfere + with the validator. We also assume that the 64-bit 'chain hash' + value is unique for every lock-chain in the system. Also, lock + recursion must not be higher than 20. + +Performance: +------------ + +The above rules require _massive_ amounts of runtime checking. If we did +that for every lock taken and for every irqs-enable event, it would +render the system practically unusably slow. The complexity of checking +is O(N^2), so even with just a few hundred lock-classes we'd have to do +tens of thousands of checks for every event. + +This problem is solved by checking any given 'locking scenario' (unique +sequence of locks taken after each other) only once. A simple stack of +held locks is maintained, and a lightweight 64-bit hash value is +calculated, which hash is unique for every lock chain. The hash value, +when the chain is validated for the first time, is then put into a hash +table, which hash-table can be checked in a lockfree manner. If the +locking chain occurs again later on, the hash table tells us that we +dont have to validate the chain again. diff --git a/Documentation/memory-barriers.txt b/Documentation/memory-barriers.txt index 28d1bc3edb1c..46b9b389df35 100644 --- a/Documentation/memory-barriers.txt +++ b/Documentation/memory-barriers.txt @@ -1015,10 +1015,9 @@ CPU from reordering them.
