+Delay accounting
+----------------
+
+Tasks encounter delays in execution when they wait
+for some kernel resource to become available e.g. a
+runnable task may wait for a free CPU to run on.
+
+The per-task delay accounting functionality measures
+the delays experienced by a task while
+
+a) waiting for a CPU (while being runnable)
+b) completion of synchronous block I/O initiated by the task
+c) swapping in pages
+
+and makes these statistics available to userspace through
+the taskstats interface.
+
+Such delays provide feedback for setting a task's cpu priority,
+io priority and rss limit values appropriately. Long delays for
+important tasks could be a trigger for raising its corresponding priority.
+
+The functionality, through its use of the taskstats interface, also provides
+delay statistics aggregated for all tasks (or threads) belonging to a
+thread group (corresponding to a traditional Unix process). This is a commonly
+needed aggregation that is more efficiently done by the kernel.
+
+Userspace utilities, particularly resource management applications, can also
+aggregate delay statistics into arbitrary groups. To enable this, delay
+statistics of a task are available both during its lifetime as well as on its
+exit, ensuring continuous and complete monitoring can be done.
+
+
+Interface
+---------
+
+Delay accounting uses the taskstats interface which is described
+in detail in a separate document in this directory. Taskstats returns a
+generic data structure to userspace corresponding to per-pid and per-tgid
+statistics. The delay accounting functionality populates specific fields of
+this structure. See
+ include/linux/taskstats.h
+for a description of the fields pertaining to delay accounting.
+It will generally be in the form of counters returning the cumulative
+delay seen for cpu, sync block I/O, swapin etc.
+
+Taking the difference of two successive readings of a given
+counter (say cpu_delay_total) for a task will give the delay
+experienced by the task waiting for the corresponding resource
+in that interval.
+
+When a task exits, records containing the per-task statistics
+are sent to userspace without requiring a command. If it is the last exiting
+task of a thread group, the per-tgid statistics are also sent. More details
+are given in the taskstats interface description.
+
+The getdelays.c userspace utility in this directory allows simple commands to
+be run and the corresponding delay statistics to be displayed. It also serves
+as an example of using the taskstats interface.
+
+Usage
+-----
+
+Compile the kernel with
+ CONFIG_TASK_DELAY_ACCT=y
+ CONFIG_TASKSTATS=y
+
+Delay accounting is enabled by default at boot up.
+To disable, add
+ nodelayacct
+to the kernel boot options. The rest of the instructions
+below assume this has not been done.
+
+After the system has booted up, use a utility
+similar to getdelays.c to access the delays
+seen by a given task or a task group (tgid).
+The utility also allows a given command to be
+executed and the corresponding delays to be
+seen.
+
+General format of the getdelays command
+
+getdelays [-t tgid] [-p pid] [-c cmd...]
+
+
+Get delays, since system boot, for pid 10
+# ./getdelays -p 10
+(output similar to next case)
+
+Get sum of delays, since system boot, for all pids with tgid 5
+# ./getdelays -t 5
+

+IO count delay total

+Per-task statistics interface
+-----------------------------
+
+
+Taskstats is a netlink-based interface for sending per-task and
+per-process statistics from the kernel to userspace.
+
+Taskstats was designed for the following benefits:
+
+- efficiently provide statistics during lifetime of a task and on its exit
+- unified interface for multiple accounting subsystems
+- extensibility for use by future accounting patches
+
+Terminology
+-----------
+
+"pid", "tid" and "task" are used interchangeably and refer to the standard
+Linux task defined by struct task_struct. per-pid stats are the same as
+per-task stats.
+
+"tgid", "process" and "thread group" are used interchangeably and refer to the
+tasks that share an mm_struct i.e. the traditional Unix process. 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.

+relay interface (formerly relayfs)
+==================================
+
+The relay interface provides a means for kernel applications to
+efficiently log and transfer large quantities of data from the kernel
+to userspace via user-defined 'relay channels'.
+
+A 'relay channel' is a kernel->user data relay mechanism implemented
+as a set of per-cpu kernel buffers ('channel buffers'), each
+represented as a regular file ('relay file') in user space. Kernel
+clients write into the channel buffers using efficient write
+functions; these automatically log into the current cpu's channel
+buffer. User space applications mmap() or read() from the relay files
+and retrieve the data as it becomes available. 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.

-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'. A channel consists
-of a set of per-cpu kernel buffers each represented by a file in the
-relayfs filesystem. Kernel clients write into a channel using
-efficient write functions which automatically log to the current cpu's
-channel buffer. User space applications mmap() the per-cpu files and
-retrieve the data as it becomes available.
-
-The format of the data logged into the channel buffers is completely
-up to the relayfs client; relayfs does however provide hooks which
-allow clients to impose some structure on the buffer data. Nor does
-relayfs implement any form of data filtering - this also is left to
-the client. The purpose is to keep relayfs as simple as possible.

-This document provides an overview of the relayfs API. The details of
-the function parameters are documented along with the functions in the
-filesystem code - please see that for details.

-
-Each relayfs channel has one buffer per CPU, each buffer has one or

- sure that all logging to the channel has ended before using
- read() with overwrite mode.
-
-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 relayfs files, the
-relayfs filesystem must be mounted. For example,
-
- mount -t relayfs relayfs /mnt/relay
-
-NOTE: relayfs 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.

- channel management functions:
-
- relay_open(base_filename, parent, subbuf_size, n_subbufs,
- callbacks)
- relay_close(chan)
- relay_flush(chan)

- relayfs_create_dir(name, parent)
- relayfs_remove_dir(dentry)
- relayfs_create_file(name, parent, mode, fops, data)

-
- write functions:
-
- relay_write(chan, data, length)
- __relay_write(chan, data, length)
- relay_reserve(chan, length)
-
- callbacks:

-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 relayfs filesystem, which can be opened and
-mmapped from user space if desired. 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 you want a
-directory structure to contain your relayfs files, you can create it
-with relayfs_create_dir() and pass the parent directory to
-relay_open(). Clients are responsible for cleaning up any directory
-structure they create when the channel is closed - use
-relayfs_remove_dir() for that.
-
-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.
-
-Channel 'modes'
----------------
-
-relayfs 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. 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 enought,
-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 relayfs 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 go ahead with the sub-buffer switch.
-
-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 relayfs 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.
-
-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.

+filesystem mounted via NFS. The following text describes on how to use NFS
+for the root filesystem. For the rest of this text 'client' means the
diskless system, and 'server' means the NFS server.
1.) Enabling nfsroot capabilities
-----------------------------
-In order to use nfsroot you have to select support for NFS during
-kernel configuration. Note that NFS cannot be loaded as a module
-in this case. The configuration script will then ask you whether
-you want to use nfsroot, and if yes what kind of auto configuration
-system you want to use. Selecting both BOOTP and RARP is safe.
+In order to use nfsroot, NFS client support needs to be selected as
+built-in during configuration. Once this has been selected, the nfsroot
+option will become available, which should also be selected.
+
+In the networking options, kernel level autoconfiguration can be selected,
+along with the types of autoconfiguration to support. Selecting all of
+DHCP, BOOTP and RARP is safe.
2.) Kernel command line
-------------------
-When the kernel has been loaded by a boot loader (either by loadlin,
-LILO or a network boot program) it has to be told what root fs device
-to use, and where to find the server and the name of the directory
-on the server to mount as root. This can be established by a couple
-of kernel command line parameters:
+When the kernel has been loaded by a boot loader (see below) it needs to be
+told what root fs device to use. And in the case of nfsroot, where to find
+both the server and the name of the directory on the server to mount as root.
+This can be established using the following kernel command line parameters:
root=/dev/nfs
nfsroot=[<server-ip>:]<root-dir>[,<nfs-options>]
- If the `nfsroot' parameter is NOT given on the command line, the default
- "/tftpboot/%s" will be used.

+ the default "/tftpboot/%s" will be used.
- <server-ip> Specifies the IP address of the NFS server. If this field
- is not given, the default address as determined by the
- `ip' variable (see below) is used. One use of this
- parameter is for example to allow using different servers
- for RARP and NFS. Usually you can leave this blank.
+ <server-ip> Specifies the IP address of the NFS server.

- there is a "%s" token in the string, the token will be
- replaced by the ASCII-representation of the client's IP
- address.

- will be used:

This parameter tells the kernel how to configure IP addresses of devices
- and also how to set up the IP routing table. It was originally called `nfsaddrs',
- but now the boot-time IP configuration works independently of NFS, so it
- was renamed to `ip' and the old name remained as an alias for compatibility

If this parameter is missing from the kernel command line, all fields are
assumed to be empty, and the defaults mentioned below apply. In general
- this means that the kernel tries to configure everything using both
- RARP and BOOTP (depending on what has been enabled during kernel confi-
- guration, and if both what protocol answer got in first).
+ this means that the kernel tries to configure everything using
+ autoconfiguration.
+
+ The <autoconf> parameter can appear alone as the value to the `ip'
+ parameter (without all the ':' characters before) in which case auto-
+ configuration is used.
+
+ <client-ip> IP address of the client.
- <client-ip> IP address of the client. If empty, the address will either
- be determined by RARP or BOOTP. What protocol is used de-
- pends on what has been enabled during kernel configuration
- and on the <autoconf> parameter. If this parameter is not
- empty, neither RARP nor BOOTP will be used.
+ Default: Determined using autoconfiguration.
<server-ip> IP address of the NFS server. If RARP is used to determine
the client address and this parameter is NOT empty only
- replies from the specified server are accepted. To use
- different RARP and NFS server, specify your RARP server
- here (or leave it blank), and specify your NFS server in
- the `nfsroot' parameter (see above). If this entry is blank
- the address of the server is used which answered the RARP
- or BOOTP request.
-
- <gw-ip> IP address of a gateway if the server is on a different
- subnet. If this entry is empty no gateway is used and the
- server is assumed to be on the local network, unless a
- value has been received by BOOTP.

- <hostname> Name of the client. If empty, the client IP address is
- used in ASCII notation, or the value received by BOOTP.
+ Default: Determined using autoconfiguration.
- <device> Name of network device to use. If this is empty, all
- devices are used for RARP and BOOTP requests, and the

-3.) Kernel loader
- -------------
+ Default: any
-To get the kernel into memory different approaches can be used. They
-depend on what facilities are available:
-3.1) Writing the kernel onto a floppy using dd:
- As always you can just write the kernel onto a floppy using dd,
- but then it's not possible to use kernel command lines at all.
- To substitute the 'root=' parameter, create a dummy device on any
- linux system with major number 0 and minor number 255 using mknod:
- mknod /dev/boot255 c 0 255
+3.) Boot Loader
+ ----------
- Then copy the kernel zImage file onto a floppy using dd:
+To get the kernel into memory different approaches can be used.
+They depend on various facilities being available:
- dd if=/usr/src/linux/arch/i386/boot/zImage of=/dev/fd0
- And finally use rdev to set the root device:
+3.1) Booting from a floppy using syslinux
- rdev /dev/fd0 /dev/boot255
+ When building kernels, an easy way to create a boot floppy that uses
+ syslinux is to use the zdisk or bzdisk make targets which use
+ and bzimage images respectively. Both targets accept the
+ FDARGS parameter which can be used to set the kernel command line.
- You can then remove the dummy device /dev/boot255 again. There
- is no real device available for it.
- The other two kernel command line parameters cannot be substi-
- tuted with rdev. Therefore, using this method the kernel will
- by default use RARP and/or BOOTP, and if it gets an answer via
- RARP will mount the directory /tftpboot/<client-ip>/ as its
- root. If it got a BOOTP answer the directory name in that answer
- is used.
+ e.g.
+ make bzdisk FDARGS="root=/dev/nfs"
+
+ Note that the user running this command will need to have
+ access to the floppy drive device, /dev/fd0
+
+ For more information on syslinux, including how to create bootdisks
+ for prebuilt kernels, see http://syslinux.zytor.com/
+
+ N.B: Previously it was possible to write a kernel directly to
+ a floppy using dd, configure the boot device using rdev, and
+ boot using the resulting floppy. Linux no longer supports this
+ method of booting.
+
+3.2) Booting from a cdrom using isolinux
+
+ When building kernels, an easy way to create a bootable cdrom that
+ uses isolinux is to use the isoimage target which uses a bzimage
+ image. Like zdisk and bzdisk, this target accepts the FDARGS
+ parameter which can be used to set the kernel command line.
+
+ e.g.
+ make isoimage FDARGS="root=/dev/nfs"
+
+ The resulting iso image will be arch/<ARCH>/boot/image.iso
+ This can be written to a cdrom using a variety of tools including
+ cdrecord.
+
+ e.g.
+ cdrecord dev=ATAPI:1,0,0 arch/i386/boot/image.iso
+
+ For more information on isolinux, including how to create bootdisks
+ for prebuilt kernels, see http://syslinux.zytor.com/
3.2) Using LILO
- When using LILO you can specify all necessary command line
- parameters with the 'append=' command in the LILO configuration
- file. However, to use the 'root=' command you also need to
- set up a dummy device as described in 3.1 above. For how to use
- LILO and its 'append=' command please refer to the LILO
- documentation.
+ When using LILO all the necessary command line parameters may be
+ specified using the 'append=' directive in the LILO configuration
+ file.
+
+ However, to use the 'root=' directive you also need to create
+ a dummy root device, which may be removed after LILO is run.
+
+ mknod /dev/boot255 c 0 255
+
+ For information on configuring LILO, please refer to its documentation.
3.3) Using GRUB
- When you use GRUB, you simply append the parameters after the kernel
- specification: "kernel <kernel> <parameters>" (without the quotes).
+ When using GRUB, kernel parameter are simply appended after the kernel
+ specification: kernel <kernel> <parameters>
3.4) Using loadlin
- When you want to boot Linux from a DOS command prompt without
- having a local hard disk to mount as root, you can use loadlin.
- I was told that it works, but haven't used it myself yet. In
- general you should be able to create a kernel command line simi-
- lar to how LILO is doing it. Please refer to the loadlin docu-
- mentation for further information.
+ loadlin may be used to boot Linux from a DOS command prompt without
+ requiring a local hard disk to mount as root. This has not been
+ thoroughly tested by the authors of this document, but in general
+ it should be possible configure the kernel command line similarly
+ to the configuration of LILO.
+
+ Please refer to the loadlin documentation for further information.
3.5) Using a boot ROM
- This is probably the most elegant way of booting a diskless
- client. With a boot ROM the kernel gets loaded using the TFTP
- protocol. As far as I know, no commercial boot ROMs yet
- support booting Linux over the network, but there are two
- free implementations of a boot ROM available on sunsite.unc.edu
- and its mirrors. They are called 'netboot-nfs' and 'etherboot'.
- Both contain everything you need to boot a diskless Linux client.
+ This is probably the most elegant way of booting a diskless client.

+ etherboot, both of which are available on sunsite.unc.edu, and both
+ of which contain everything you need to boot a diskless Linux client.
3.6) Using pxelinux
- Using pxelinux you specify the kernel you built with
+ Pxelinux may be used to boot linux using the PXE boot loader
+ which is present on many modern network cards.
+
+ When using pxelinux, the kernel image is specified using
"kernel <relative-path-below /tftpboot>". The nfsroot parameters
are passed to the kernel by adding them to the "append" line.
- You may perhaps also want to fine tune the console output,
- see Documentation/serial-console.txt for serial console help.
+ It is common to use serial console in conjunction with pxeliunx,
+ see Documentation/serial-console.txt for more information.
+
+ For more information on isolinux, including how to create bootdisks
+ for prebuilt kernels, see http://syslinux.zytor.com/

- *
- * 1) We handle one interrupt and return, sitting in a loop and moving across

- * common case is one pending IRQ so optimize in that direction.
- *
- * 2) We need not check against bits in the status register IRQ mask, that
- * would make this routine slow as hell.
- *
- * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in
- * between like BSD spl() brain-damage.
- *
- * Furthermore, the IRQs on the MIPS board look basically (barring software
- * IRQs which we don't use at all and all external interrupt sources are
- * combined together on hardware interrupt 0 (MIPS IRQ 2)) like:
- *
- * MIPS IRQ Source
- * -------- ------
- * 0 Software (ignored)
- * 1 Software (ignored)
- * 2 Combined hardware interrupt (hw0)
- * 3 Hardware (ignored)
- * 4 Hardware (ignored)
- * 5 Hardware (ignored)
- * 6 Hardware (ignored)
- * 7 R4k timer (what we use)
- *
- * Note: On the SEAD board thing are a little bit different.
- * Here IRQ 2 (hw0) is wired to the UART0 and IRQ 3 (hw1) is wired
- * wired to UART1.
- *
- * We handle the IRQ according to _our_ priority which is:
- *
- * Highest ---- R4k Timer
- * Lowest ---- Combined hardware interrupt
- *
- * then we just return, if multiple IRQs are pending then we will just take
- * another exception, big deal.

-
- 0.99H+lk0.9 - David S. Miller - softnet, PCI DMA updates
- 0.99H+lk1.0 - Jeff Garzik <jgarzik@pobox.com>
- Remove compatibility defines for kernel versions < 2.2.x.
- Update for new 2.3.x module interface
- LK1.1.2 (March 19, 2000)

- - Select window 3 in vortex_timer()'s write to Wn3_MAC_Ctrl
- - In vortex_start_xmit(), move the lock to _after_ we've altered
- vp->cur_tx and vp->tx_full. This defeats the race between
- vortex_start_xmit() and vortex_interrupt which was identified
- by Bogdan Costescu.
- - Merged back support for six new cards from various sources
- - Set vortex_have_pci if pci_module_init returns zero (fixes cardbus
- insertion oops)
- - Tell it that 3c905C has NWAY for 100bT autoneg

- - Fix MOD_INC/DEC races
- - Handle resource allocation failures.
- - Fix 3CCFE575CT LED polarity
- - Make tx_interrupt_mitigation the default
-
- LK1.1.4 25 April 2000, Andrew Morton <andrewm@uow.edu.au>
- - Add extra TxReset to vortex_up() to fix 575_cb hotplug initialisation probs.
- - Put vortex_info_tbl into __devinitdata
- - In the vortex_error StatsFull HACK, disable stats in vp->intr_enable as well
- as in the hardware.
- - Increased the loop counter in issue_and_wait from 2,000 to 4,000.
-
- LK1.1.5 28 April 2000, andrewm
- - Added powerpc defines (John Daniel <jdaniel@etresoft.com> said these work...)
- - Some extra diagnostics
- - In vortex_error(), reset the Tx on maxCollisions. Otherwise most
- chips usually get a Tx timeout.
- - Added extra_reset module parm
- - Replaced some inline timer manip with mod_timer
- (Franois romieu <Francois.Romieu@nic.fr>)
- - In vortex_up(), don't make Wn3_config initialisation dependent upon has_nway
- (this came across from 3c575_cb).
-
- LK1.1.6 06 Jun 2000, andrewm
- - Backed out the PPC defines.
- - Use del_timer_sync(), mod_timer().
- - Fix wrapped ulong comparison in boomerang_rx()
- - Add IS_TORNADO, use it to suppress 3c905C checksum error msg
- (Donald Becker, I Lee Hetherington <ilh@sls.lcs.mit.edu>)
- - Replace union wn3_config with BFINS/BFEXT manipulation for
- sparc64 (Pete Zaitcev, Peter Jones)
- - In vortex_error, do_tx_reset and vortex_tx_timeout(Vortex):
- do a netif_wake_queue() to better recover from errors. (Anders Pedersen,
- Donald Becker)
- - Print a warning on out-of-memory (rate limited to 1 per 10 secs)
- - Added two more Cardbus 575 NICs: 5b57 and 6564 (Paul Wagland)
-
- LK1.1.7 2 Jul 2000 andrewm
- - Better handling of shared IRQs
- - Reset the transmitter on a Tx reclaim error
- - Fixed crash under OOM during vortex_open() (Mark Hemment)
- - Fix Rx cessation problem during OOM (help from Mark Hemment)
- - The spinlocks around the mdio access were blocking interrupts for 300uS.
- Fix all this to use spin_lock_bh() within mdio_read/write
- - Only write to TxFreeThreshold if it's a boomerang - other NICs don't
- have one.
- - Added 802.3x MAC-layer flow control support
-
- LK1.1.8 13 Aug 2000 andrewm
- - Ignore request_region() return value - already reserved if Cardbus.
- - Merged some additional Cardbus flags from Don's 0.99Qk
- - Some fixes for 3c556 (Fred Maciel)
- - Fix for EISA initialisation (Jan Rekorajski)
- - Renamed MII_XCVR_PWR and EEPROM_230 to align with 3c575_cb and D. Becker's drivers
- - Fixed MII_XCVR_PWR for 3CCFE575CT
- - Added INVERT_LED_PWR, used it.
- - Backed out the extra_reset stuff
-
- LK1.1.9 12 Sep 2000 andrewm
- - Backed out the tx_reset_resume flags. It was a no-op.
- - In vortex_error, don't reset the Tx on txReclaim errors
- - In vortex_error, don't reset the Tx on maxCollisions errors.
- Hence backed out all the DownListPtr logic here.
- - In vortex_error, give Tornado cards a partial TxReset on
- maxCollisions (David Hinds). Defined MAX_COLLISION_RESET for this.
- - Redid some driver flags and device names based on pcmcia_cs-3.1.20.
- - Fixed a bug where, if vp->tx_full is set when the interface
- is downed, it remains set when the interface is upped. Bad
- things happen.
-
- LK1.1.10 17 Sep 2000 andrewm
- - Added EEPROM_8BIT for 3c555 (Fred Maciel)
- - Added experimental support for the 3c556B Laptop Hurricane (Louis Gerbarg)
- - Add HAS_NWAY to "3c900 Cyclone 10Mbps TPO"

- - Add 3c590 PCI latency timer hack to vortex_probe1 (from 0.99Ra)
- - Added extended issue_and_wait for the 3c905CX.
- - Look for an MII on PHY index 24 first (3c905CX oddity).
- - Add HAS_NWAY to 3cSOHO100-TX (Brett Frankenberger)
- - Don't free skbs we don't own on oom path in vortex_open().
-
- LK1.1.13 27 Jan 2001
- - Added explicit `medialock' flag so we can truly
- lock the media type down with `options'.
- - "check ioremap return and some tidbits" (Arnaldo Carvalho de Melo <acme@conectiva.com.br>)
- - Added and used EEPROM_NORESET for 3c556B PM resumes.

- use it, even if autoselect is enabled.
-
- LK1.1.15 6 June 2001 akpm
- - Prevent double counting of received bytes (Lars Christensen)
- - Add ethtool support (jgarzik)

- - Special-case the 'Tx error 82' message.
-
- LK1.1.16 18 July 2001 akpm
- - Make NETIF_F_SG dependent upon nr_free_highpages(), not on CONFIG_HIGHMEM
- - Lessen verbosity of bootup messages
- - Fix WOL - use new PM API functions.
- - Use netif_running() instead of vp->open in suspend/resume.
- - Don't reset the interface logic on open/close/rmmod. It upsets
- autonegotiation, and hence DHCP (from 0.99T).
- - Back out EEPROM_NORESET flag because of the above (we do it for all
- NICs).
- - Correct 3c982 identification string
- - Rename wait_for_completion() to issue_and_wait() to avoid completion.h
- clash.
-
- LK1.1.17 18Dec01 akpm
- - PCI ID 9805 is a Python-T, not a dual-port Cyclone. Apparently.
- And it has NWAY.
- - Mask our advertised modes (vp->advertising) with our capabilities
- (MII reg5) when deciding which duplex mode to use.
- - Add `global_options' as default for options[]. Ditto global_enable_wol,
- global_full_duplex.
-
- LK1.1.18 01Jul02 akpm
- - Fix for undocumented transceiver power-up bit on some 3c566B's
- (Donald Becker, Rahul Karnik)
-
- - See http://www.zip.com.au/~akpm/linux/#3c59x-2.3 for more details.
- - Also see Documentation/networking/vortex.txt
-
- LK1.1.19 10Nov02 Marc Zyngier <maz@wild-wind.fr.eu.org>
- - EISA sysfs integration.

Support information and updates available at
http://www.scyld.com/network/netsemi.html
+ [link no longer provides useful info -jgarzik]
- Linux kernel modifications:
-
- Version 1.0.1:
- - Spinlock fixes
- - Bug fixes and better intr performance (Tjeerd)
- Version 1.0.2:
- - Now reads correct MAC address from eeprom
- Version 1.0.3:
- - Eliminate redundant priv->tx_full flag
- - Call netif_start_queue from dev->tx_timeout
- - wmb() in start_tx() to flush data
- - Update Tx locking
- - Clean up PCI enable (davej)
- Version 1.0.4:
- - Merge Donald Becker's natsemi.c version 1.07
- Version 1.0.5:
- - { fill me in }
- Version 1.0.6:
- * ethtool support (jgarzik)
- * Proper initialization of the card (which sometimes
- fails to occur and leaves the card in a non-functional
- state). (uzi)
-
- * Some documented register settings to optimize some
- of the 100Mbit autodetection circuitry in rev C cards. (uzi)
-
- * Polling of the PHY intr for stuff like link state
- change and auto- negotiation to finally work properly. (uzi)
-
- * One-liner removal of a duplicate declaration of
- netdev_error(). (uzi)
-
- Version 1.0.7: (Manfred Spraul)
- * pci dma
- * SMP locking update
- * full reset added into tx_timeout
- * correct multicast hash generation (both big and little endian)
- [copied from a natsemi driver version
- from Myrio Corporation, Greg Smith]
- * suspend/resume
-
- version 1.0.8 (Tim Hockin <thockin@sun.com>)
- * ETHTOOL_* support
- * Wake on lan support (Erik Gilling)
- * MXDMA fixes for serverworks
- * EEPROM reload
-
- version 1.0.9 (Manfred Spraul)
- * Main change: fix lack of synchronize
- netif_close/netif_suspend against a last interrupt
- or packet.
- * do not enable superflous interrupts (e.g. the
- drivers relies on TxDone - TxIntr not needed)
- * wait that the hardware has really stopped in close
- and suspend.
- * workaround for the (at least) gcc-2.95.1 compiler
- problem. Also simplifies the code a bit.
- * disable_irq() in tx_timeout - needed to protect
- against rx interrupts.
- * stop the nic before switching into silent rx mode
- for wol (required according to docu).
-
- version 1.0.10:
- * use long for ee_addr (various)
- * print pointers properly (DaveM)
- * include asm/irq.h (?)
-
- version 1.0.11:
- * check and reset if PHY errors appear (Adrian Sun)
- * WoL cleanup (Tim Hockin)
- * Magic number cleanup (Tim Hockin)
- * Don't reload EEPROM on every reset (Tim Hockin)
- * Save and restore EEPROM state across reset (Tim Hockin)
- * MDIO Cleanup (Tim Hockin)
- * Reformat register offsets/bits (jgarzik)
-
- version 1.0.12:
- * ETHTOOL_* further support (Tim Hockin)
-
- version 1.0.13:
- * ETHTOOL_[G]EEPROM support (Tim Hockin)
-
- version 1.0.13:
- * crc cleanup (Matt Domsch <Matt_Domsch@dell.com>)
-
- version 1.0.14:
- * Cleanup some messages and autoneg in ethtool (Tim Hockin)
-
- version 1.0.15:
- * Get rid of cable_magic flag
- * use new (National provided) solution for cable magic issue
-
- version 1.0.16:
- * call netdev_rx() for RxErrors (Manfred Spraul)
- * formatting and cleanups
- * change options and full_duplex arrays to be zero
- initialized
- * enable only the WoL and PHY interrupts in wol mode
-
- version 1.0.17:
- * only do cable_magic on 83815 and early 83816 (Tim Hockin)
- * create a function for rx refill (Manfred Spraul)
- * combine drain_ring and init_ring (Manfred Spraul)
- * oom handling (Manfred Spraul)
- * hands_off instead of playing with netif_device_{de,a}ttach
- (Manfred Spraul)
- * be sure to write the MAC back to the chip (Manfred Spraul)
- * lengthen EEPROM timeout, and always warn about timeouts
- (Manfred Spraul)
- * comments update (Manfred)
- * do the right thing on a phy-reset (Manfred and Tim)
-

+ [link no longer provides useful info -jgarzik]
-
- Version LK1.01a (jgarzik):
- - Replace some MII-related magic numbers with constants
-
- Version LK1.02 (D-Link):
- - Add new board to PCI ID list
- - Fix multicast bug
-
- Version LK1.03 (D-Link):
- - New Rx scheme, reduce Rx congestion
- - Option to disable flow control
-
- Version LK1.04 (D-Link):
- - Tx timeout recovery
- - More support for ethtool.
-
- Version LK1.04a:
- - Remove unused/constant members from struct pci_id_info
- (which then allows removal of 'drv_flags' from private struct)
- (jgarzik)
- - If no phy is found, fail to load that board (jgarzik)
- - Always start phy id scan at id 1 to avoid problems (Donald Becker)
- - Autodetect where mii_preable_required is needed,
- default to not needed. (Donald Becker)
-
- Version LK1.04b:
- - Remove mii_preamble_required module parameter (Donald Becker)
- - Add per-interface mii_preamble_required (setting is autodetected)
- (Donald Becker)
- - Remove unnecessary cast from void pointer (jgarzik)
- - Re-align comments in private struct (jgarzik)
-
- Version LK1.04c (jgarzik):
- - Support bitmapped message levels (NETIF_MSG_xxx), and the
- two ethtool ioctls that get/set them
- - Don't hand-code MII ethtool support, use standard API/lib
-
- Version LK1.04d:
- - Merge from Donald Becker's sundance.c: (Jason Lunz)
- * proper support for variably-sized MTUs
- * default to PIO, to fix chip bugs
- - Add missing unregister_netdev (Jason Lunz)
- - Add CONFIG_SUNDANCE_MMIO config option (jgarzik)
- - Better rx buf size calculation (Donald Becker)
-
- Version LK1.05 (D-Link):
- - Fix DFE-580TX packet drop issue (for DL10050C)
- - Fix reset_tx logic
-
- Version LK1.06 (D-Link):
- - Fix crash while unloading driver

- - New tx scheme, adaptive tx_coalesce
-
- Version LK1.07 (D-Link):
- - Fix tx bugs in big-endian machines
- - Remove unused max_interrupt_work module parameter, the new
- NAPI-like rx scheme doesn't need it.
- - Remove redundancy get_stats() in intr_handler(), those
- I/O access could affect performance in ARM-based system
- - Add Linux software VLAN support
-
- Version LK1.08 (Philippe De Muyter phdm@macqel.be):
- - Fix bug of custom mac address
- (StationAddr register only accept word write)
-
- Version LK1.09 (D-Link):
- - Fix the flowctrl bug.
- - Set Pause bit in MII ANAR if flow control enabled.
-
- Version LK1.09a (ICPlus):
- - Add the delay time in reading the contents of EEPROM

-
- LK1.1.2:
- - Urban Widmark: minor cleanups, merges from Becker 1.03a/1.04 versions
-
- LK1.1.3:
- - Urban Widmark: use PCI DMA interface (with thanks to the eepro100.c
- code) update "Theory of Operation" with
- softnet/locking changes
- - Dave Miller: PCI DMA and endian fixups
- - Jeff Garzik: MOD_xxx race fixes, updated PCI resource allocation
-
- LK1.1.4:
- - Urban Widmark: fix gcc 2.95.2 problem and
- remove writel's to fixed address 0x7c
-
- LK1.1.5:
- - Urban Widmark: mdio locking, bounce buffer changes
- merges from Beckers 1.05 version
- added netif_running_on/off support
-
- LK1.1.6:
- - Urban Widmark: merges from Beckers 1.08b version (VT6102 + mdio)
- set netif_running_on/off on startup, del_timer_sync
-
- LK1.1.7:
- - Manfred Spraul: added reset into tx_timeout
-
- LK1.1.9:
- - Urban Widmark: merges from Beckers 1.10 version
- (media selection + eeprom reload)
- - David Vrabel: merges from D-Link "1.11" version
- (disable WOL and PME on startup)
-
- LK1.1.10:
- - Manfred Spraul: use "singlecopy" for unaligned buffers
- don't allocate bounce buffers for !ReqTxAlign cards
-
- LK1.1.11:
- - David Woodhouse: Set dev->base_addr before the first time we call
- wait_for_reset(). It's a lot happier that way.
- Free np->tx_bufs only if we actually allocated it.
-
- LK1.1.12:
- - Martin Eriksson: Allow Memory-Mapped IO to be enabled.
-
- LK1.1.13 (jgarzik):
- - Add ethtool support
- - Replace some MII-related magic numbers with constants
-
- LK1.1.14 (Ivan G.):
- - fixes comments for Rhine-III
- - removes W_MAX_TIMEOUT (unused)
- - adds HasDavicomPhy for Rhine-I (basis: linuxfet driver; my card
- is R-I and has Davicom chip, flag is referenced in kernel driver)
- - sends chip_id as a parameter to wait_for_reset since np is not
- initialized on first call
- - changes mmio "else if (chip_id==VT6102)" to "else" so it will work
- for Rhine-III's (documentation says same bit is correct)
- - transmit frame queue message is off by one - fixed
- - adds IntrNormalSummary to "Something Wicked" exclusion list
- so normal interrupts will not trigger the message (src: Donald Becker)
- (Roger Luethi)
- - show confused chip where to continue after Tx error
- - location of collision counter is chip specific
- - allow selecting backoff algorithm (module parameter)
-
- LK1.1.15 (jgarzik):
- - Use new MII lib helper generic_mii_ioctl
-
- LK1.1.16 (Roger Luethi)
- - Etherleak fix
- - Handle Tx buffer underrun
- - Fix bugs in full duplex handling
- - New reset code uses "force reset" cmd on Rhine-II
- - Various clean ups
-
- LK1.1.17 (Roger Luethi)
- - Fix race in via_rhine_start_tx()
- - On errors, wait for Tx engine to turn off before scavenging
- - Handle Tx descriptor write-back race on Rhine-II
- - Force flushing for PCI posted writes
- - More reset code changes
-
- LK1.1.18 (Roger Luethi)
- - No filtering multicast in promisc mode (Edward Peng)
- - Fix for Rhine-I Tx timeouts
-
- LK1.1.19 (Roger Luethi)
- - Increase Tx threshold for unspecified errors
-

Portions copied from the Keyspan driver by Hugh Blemings <hugh@blemings.org>
- History:
-
- 2005-05-19 v0.1 Initial version, based on incomplete docs
- and analysis of misbehavior with the standard driver
- 2005-05-20 v0.2 Extended the input buffer to avoid losing
- random 64-byte chunks of data
- 2005-05-21 v0.3 implemented chars_in_buffer()
- turned on low_latency
- simplified the code somewhat
- 2005-05-24 v0.4 option_write() sometimes deadlocked under heavy load
- removed some dead code
- added sponsor notice
- coding style clean-up
- 2005-06-20 v0.4.1 add missing braces :-/
- killed end-of-line whitespace
- 2005-07-15 v0.4.2 rename WLAN product to FUSION, add FUSION2
- 2005-09-10 v0.4.3 added HUAWEI E600 card and Audiovox AirCard
- 2005-09-20 v0.4.4 increased recv buffer size: the card sometimes
- wants to send >2000 bytes.
- 2006-04-10 v0.5 fixed two array overrun errors :-/
- 2006-04-21 v0.5.1 added support for Sierra Wireless MC8755
- 2006-05-15 v0.6 re-enable multi-port support
- 2006-06-01 v0.6.1 add COBRA
- 2006-06-01 v0.6.2 add backwards-compatibility stuff
- 2006-06-01 v0.6.3 add Novatel Wireless
- 2006-06-01 v0.7 Option => GSM
+ History: see the git log.
Work sponsored by: Sigos GmbH, Germany <info@sigos.de>
This driver exists because the "normal" serial driver doesn't work too well
with GSM modems. Issues:
- data loss -- one single Receive URB is not nearly enough
- - nonstandard flow (Option devices) and multiplex (Sierra) control
+ - nonstandard flow (Option devices) control
- controlling the baud rate doesn't make sense
This driver is named "option" because the most common device it's
device features.

-config SYSCTL
- bool "Sysctl support" if EMBEDDED
- default y
- ---help---
- The sysctl interface provides a means of dynamically changing
- certain kernel parameters and variables on the fly without requiring
- a recompile of the kernel or reboot of the system. The primary
- interface consists of a system call, but if you say Y to "/proc
- file system support", a tree of modifiable sysctl entries will be
- generated beneath the /proc/sys directory. They are explained in the
- files in <file:Documentation/sysctl/>. Note that enabling this
- option will enlarge the kernel by at least 8 KB.
+config TASKSTATS
+ bool "Export task/process statistics through netlink (EXPERIMENTAL)"
+ depends on NET
+ default n
+ help
+ Export selected statistics for tasks/processes through the
+ generic netlink interface. Unlike BSD process accounting, the
+ statistics are available during the lifetime of tasks/processes as
+ responses to commands. Like BSD accounting, they are sent to user
+ space on task exit.
- As it is generally a good thing, you should say Y here unless
- building a kernel for install/rescue disks or your system is very
- limited in memory.
+ Say N if unsure.
+
+config TASK_DELAY_ACCT
+ bool "Enable per-task delay accounting (EXPERIMENTAL)"
+ depends on TASKSTATS
+ help
+ Collect information on time spent by a task waiting for system
+ resources like cpu, synchronous block I/O completion and swapping
+ in pages. Such statistics can help in setting a task's priorities
+ relative to other tasks for cpu, io, rss limits etc.
+
+ Say N if unsure.

- * TCP Vegas congestion control
- *
- * This is based on the congestion detection/avoidance scheme described in
- * Lawrence S. Brakmo and Larry L. Peterson.
- * "TCP Vegas: End to end congestion avoidance on a global internet."
- * IEEE Journal on Selected Areas in Communication, 13(8):1465--1480,
- * October 1995. Available from:
- * ftp://ftp.cs.arizona.edu/xkernel/Papers/jsac.ps
- *
- * See http://www.cs.arizona.edu/xkernel/ for their implementation.
- * The main aspects that distinguish this implementation from the
- * Arizona Vegas implementation are:
- * o We do not change the loss detection or recovery mechanisms of
- * Linux in any way. Linux already recovers from losses quite well,
- * using fine-grained timers, NewReno, and FACK.
- * o To avoid the performance penalty imposed by increasing cwnd
- * only every-other RTT during slow start, we increase during
- * every RTT during slow start, just like Reno.
- * o Largely to allow continuous cwnd growth during slow start,
- * we use the rate at which ACKs come back as the "actual"
- * rate, rather than the rate at which data is sent.
- * o To speed convergence to the right rate, we set the cwnd
- * to achieve the right ("actual") rate when we exit slow start.
- * o To filter out the noise caused by delayed ACKs, we use the
- * minimum RTT sample observed during the last RTT to calculate
- * the actual rate.
- * o When the sender re-starts from idle, it waits until it has
- * received ACKs for an entire flight of new data before making
- * a cwnd adjustment decision. The original Vegas implementation
- * assumed senders never went idle.
- *
- *
- * TCP Compound based on TCP Vegas
