1relay interface (formerly relayfs)
2==================================
3
4The relay interface provides a means for kernel applications to
5efficiently log and transfer large quantities of data from the kernel
6to userspace via user-defined 'relay channels'.
7
8A 'relay channel' is a kernel->user data relay mechanism implemented
9as a set of per-cpu kernel buffers ('channel buffers'), each
10represented as a regular file ('relay file') in user space. Kernel
11clients write into the channel buffers using efficient write
12functions; these automatically log into the current cpu's channel
13buffer. User space applications mmap() or read() from the relay files
14and retrieve the data as it becomes available. The relay files
15themselves are files created in a host filesystem, e.g. debugfs, and
16are associated with the channel buffers using the API described below.
17
18The format of the data logged into the channel buffers is completely
19up to the kernel client; the relay interface does however provide
20hooks which allow kernel clients to impose some structure on the
21buffer data. The relay interface doesn't implement any form of data
22filtering - this also is left to the kernel client. The purpose is to
23keep things as simple as possible.
24
25This document provides an overview of the relay interface API. The
26details of the function parameters are documented along with the
27functions in the relay interface code - please see that for details.
28
29Semantics
30=========
31
32Each relay channel has one buffer per CPU, each buffer has one or more
33sub-buffers. Messages are written to the first sub-buffer until it is
34too full to contain a new message, in which case it it is written to
35the next (if available). Messages are never split across sub-buffers.
36At this point, userspace can be notified so it empties the first
37sub-buffer, while the kernel continues writing to the next.
38
39When notified that a sub-buffer is full, the kernel knows how many
40bytes of it are padding i.e. unused space occurring because a complete
41message couldn't fit into a sub-buffer. Userspace can use this
42knowledge to copy only valid data.
43
44After copying it, userspace can notify the kernel that a sub-buffer
45has been consumed.
46
47A relay channel can operate in a mode where it will overwrite data not
48yet collected by userspace, and not wait for it to be consumed.
49
50The relay channel itself does not provide for communication of such
51data between userspace and kernel, allowing the kernel side to remain
52simple and not impose a single interface on userspace. It does
53provide a set of examples and a separate helper though, described
54below.
55
56The read() interface both removes padding and internally consumes the
57read sub-buffers; thus in cases where read(2) is being used to drain
58the channel buffers, special-purpose communication between kernel and
59user isn't necessary for basic operation.
60
61One of the major goals of the relay interface is to provide a low
62overhead mechanism for conveying kernel data to userspace. While the
63read() interface is easy to use, it's not as efficient as the mmap()
64approach; the example code attempts to make the tradeoff between the
65two approaches as small as possible.
66
67klog and relay-apps example code
68================================
69
70The relay interface itself is ready to use, but to make things easier,
71a couple simple utility functions and a set of examples are provided.
72
73The relay-apps example tarball, available on the relay sourceforge
74site, contains a set of self-contained examples, each consisting of a
75pair of .c files containing boilerplate code for each of the user and
76kernel sides of a relay application. When combined these two sets of
77boilerplate code provide glue to easily stream data to disk, without
78having to bother with mundane housekeeping chores.
79
80The 'klog debugging functions' patch (klog.patch in the relay-apps
81tarball) provides a couple of high-level logging functions to the
82kernel which allow writing formatted text or raw data to a channel,
83regardless of whether a channel to write into exists or not, or even
84whether the relay interface is compiled into the kernel or not. These
85functions allow you to put unconditional 'trace' statements anywhere
86in the kernel or kernel modules; only when there is a 'klog handler'
87registered will data actually be logged (see the klog and kleak
88examples for details).
89
90It is of course possible to use the relay interface from scratch,
91i.e. without using any of the relay-apps example code or klog, but
92you'll have to implement communication between userspace and kernel,
93allowing both to convey the state of buffers (full, empty, amount of
94padding). The read() interface both removes padding and internally
95consumes the read sub-buffers; thus in cases where read(2) is being
96used to drain the channel buffers, special-purpose communication
97between kernel and user isn't necessary for basic operation. Things
98such as buffer-full conditions would still need to be communicated via
99some channel though.
100
101klog and the relay-apps examples can be found in the relay-apps
102tarball on http://relayfs.sourceforge.net
103
104The relay interface user space API
105==================================
106
107The relay interface implements basic file operations for user space
108access to relay channel buffer data. Here are the file operations
109that are available and some comments regarding their behavior:
110
111open() enables user to open an _existing_ channel buffer.
112
113mmap() results in channel buffer being mapped into the caller's
114 memory space. Note that you can't do a partial mmap - you
115 must map the entire file, which is NRBUF * SUBBUFSIZE.
116
117read() read the contents of a channel buffer. The bytes read are
118 'consumed' by the reader, i.e. they won't be available
119 again to subsequent reads. If the channel is being used
120 in no-overwrite mode (the default), it can be read at any
121 time even if there's an active kernel writer. If the
122 channel is being used in overwrite mode and there are
123 active channel writers, results may be unpredictable -
124 users should make sure that all logging to the channel has
125 ended before using read() with overwrite mode. Sub-buffer
126 padding is automatically removed and will not be seen by
127 the reader.
128
129sendfile() transfer data from a channel buffer to an output file
130 descriptor. Sub-buffer padding is automatically removed
131 and will not be seen by the reader.
132
133poll() POLLIN/POLLRDNORM/POLLERR supported. User applications are
134 notified when sub-buffer boundaries are crossed.
135
136close() decrements the channel buffer's refcount. When the refcount
137 reaches 0, i.e. when no process or kernel client has the
138 buffer open, the channel buffer is freed.
139
140In order for a user application to make use of relay files, the
141host filesystem must be mounted. For example,
142
143 mount -t debugfs debugfs /debug
144
145NOTE: the host filesystem doesn't need to be mounted for kernel
146 clients to create or use channels - it only needs to be
147 mounted when user space applications need access to the buffer
148 data.
149
150
151The relay interface kernel API
152==============================
153
154Here's a summary of the API the relay interface provides to in-kernel clients:
155
156TBD(curr. line MT:/API/)
157 channel management functions:
158
159 relay_open(base_filename, parent, subbuf_size, n_subbufs,
160 callbacks)
161 relay_close(chan)
162 relay_flush(chan)
163 relay_reset(chan)
164
165 channel management typically called on instigation of userspace:
166
167 relay_subbufs_consumed(chan, cpu, subbufs_consumed)
168
169 write functions:
170
171 relay_write(chan, data, length)
172 __relay_write(chan, data, length)
173 relay_reserve(chan, length)
174
175 callbacks:
176
177 subbuf_start(buf, subbuf, prev_subbuf, prev_padding)
178 buf_mapped(buf, filp)
179 buf_unmapped(buf, filp)
180 create_buf_file(filename, parent, mode, buf, is_global)
181 remove_buf_file(dentry)
182
183 helper functions:
184
185 relay_buf_full(buf)
186 subbuf_start_reserve(buf, length)
187
188
189Creating a channel
190------------------
191
192relay_open() is used to create a channel, along with its per-cpu
193channel buffers. Each channel buffer will have an associated file
194created for it in the host filesystem, which can be and mmapped or
195read from in user space. The files are named basename0...basenameN-1
196where N is the number of online cpus, and by default will be created
197in the root of the filesystem (if the parent param is NULL). If you
198want a directory structure to contain your relay files, you should
199create it using the host filesystem's directory creation function,
200e.g. debugfs_create_dir(), and pass the parent directory to
201relay_open(). Users are responsible for cleaning up any directory
202structure they create, when the channel is closed - again the host
203filesystem's directory removal functions should be used for that,
204e.g. debugfs_remove().
205
206In order for a channel to be created and the host filesystem's files
207associated with its channel buffers, the user must provide definitions
208for two callback functions, create_buf_file() and remove_buf_file().
209create_buf_file() is called once for each per-cpu buffer from
210relay_open() and allows the user to create the file which will be used
211to represent the corresponding channel buffer. The callback should
212return the dentry of the file created to represent the channel buffer.
213remove_buf_file() must also be defined; it's responsible for deleting
214the file(s) created in create_buf_file() and is called during
215relay_close().
216
217Here are some typical definitions for these callbacks, in this case
218using debugfs:
219
220/*
221 * create_buf_file() callback. Creates relay file in debugfs.
222 */
223static struct dentry *create_buf_file_handler(const char *filename,
224 struct dentry *parent,
225 int mode,
226 struct rchan_buf *buf,
227 int *is_global)
228{
229 return debugfs_create_file(filename, mode, parent, buf,
230 &relay_file_operations);
231}
232
233/*
234 * remove_buf_file() callback. Removes relay file from debugfs.
235 */
236static int remove_buf_file_handler(struct dentry *dentry)
237{
238 debugfs_remove(dentry);
239
240 return 0;
241}
242
243/*
244 * relay interface callbacks
245 */
246static struct rchan_callbacks relay_callbacks =
247{
248 .create_buf_file = create_buf_file_handler,
249 .remove_buf_file = remove_buf_file_handler,
250};
251
252And an example relay_open() invocation using them:
253
254 chan = relay_open("cpu", NULL, SUBBUF_SIZE, N_SUBBUFS, &relay_callbacks);
255
256If the create_buf_file() callback fails, or isn't defined, channel
257creation and thus relay_open() will fail.
258
259The total size of each per-cpu buffer is calculated by multiplying the
260number of sub-buffers by the sub-buffer size passed into relay_open().
261The idea behind sub-buffers is that they're basically an extension of
262double-buffering to N buffers, and they also allow applications to
263easily implement random-access-on-buffer-boundary schemes, which can
264be important for some high-volume applications. The number and size
265of sub-buffers is completely dependent on the application and even for
266the same application, different conditions will warrant different
267values for these parameters at different times. Typically, the right
268values to use are best decided after some experimentation; in general,
269though, it's safe to assume that having only 1 sub-buffer is a bad
270idea - you're guaranteed to either overwrite data or lose events
271depending on the channel mode being used.
272
273The create_buf_file() implementation can also be defined in such a way
274as to allow the creation of a single 'global' buffer instead of the
275default per-cpu set. This can be useful for applications interested
276mainly in seeing the relative ordering of system-wide events without
277the need to bother with saving explicit timestamps for the purpose of
278merging/sorting per-cpu files in a postprocessing step.
279
280To have relay_open() create a global buffer, the create_buf_file()
281implementation should set the value of the is_global outparam to a
282non-zero value in addition to creating the file that will be used to
283represent the single buffer. In the case of a global buffer,
284create_buf_file() and remove_buf_file() will be called only once. The
285normal channel-writing functions, e.g. relay_write(), can still be
286used - writes from any cpu will transparently end up in the global
287buffer - but since it is a global buffer, callers should make sure
288they use the proper locking for such a buffer, either by wrapping
289writes in a spinlock, or by copying a write function from relay.h and
290creating a local version that internally does the proper locking.
291
292Channel 'modes'
293---------------
294
295relay channels can be used in either of two modes - 'overwrite' or
296'no-overwrite'. The mode is entirely determined by the implementation
297of the subbuf_start() callback, as described below. The default if no
298subbuf_start() callback is defined is 'no-overwrite' mode. If the
299default mode suits your needs, and you plan to use the read()
300interface to retrieve channel data, you can ignore the details of this
301section, as it pertains mainly to mmap() implementations.
302
303In 'overwrite' mode, also known as 'flight recorder' mode, writes
304continuously cycle around the buffer and will never fail, but will
305unconditionally overwrite old data regardless of whether it's actually
306been consumed. In no-overwrite mode, writes will fail, i.e. data will
307be lost, if the number of unconsumed sub-buffers equals the total
308number of sub-buffers in the channel. It should be clear that if
309there is no consumer or if the consumer can't consume sub-buffers fast
310enough, data will be lost in either case; the only difference is
311whether data is lost from the beginning or the end of a buffer.
312
313As explained above, a relay channel is made of up one or more
314per-cpu channel buffers, each implemented as a circular buffer
315subdivided into one or more sub-buffers. Messages are written into
316the current sub-buffer of the channel's current per-cpu buffer via the
317write functions described below. Whenever a message can't fit into
318the current sub-buffer, because there's no room left for it, the
319client is notified via the subbuf_start() callback that a switch to a
320new sub-buffer is about to occur. The client uses this callback to 1)
321initialize the next sub-buffer if appropriate 2) finalize the previous
322sub-buffer if appropriate and 3) return a boolean value indicating
323whether or not to actually move on to the next sub-buffer.
324
325To implement 'no-overwrite' mode, the userspace client would provide
326an implementation of the subbuf_start() callback something like the
327following:
328
329static int subbuf_start(struct rchan_buf *buf,
330 void *subbuf,
331 void *prev_subbuf,
332 unsigned int prev_padding)
333{
334 if (prev_subbuf)
335 *((unsigned *)prev_subbuf) = prev_padding;
336
337 if (relay_buf_full(buf))
338 return 0;
339
340 subbuf_start_reserve(buf, sizeof(unsigned int));
341
342 return 1;
343}
344
345If the current buffer is full, i.e. all sub-buffers remain unconsumed,
346the callback returns 0 to indicate that the buffer switch should not
347occur yet, i.e. until the consumer has had a chance to read the
348current set of ready sub-buffers. For the relay_buf_full() function
349to make sense, the consumer is reponsible for notifying the relay
350interface when sub-buffers have been consumed via
351relay_subbufs_consumed(). Any subsequent attempts to write into the
352buffer will again invoke the subbuf_start() callback with the same
353parameters; only when the consumer has consumed one or more of the
354ready sub-buffers will relay_buf_full() return 0, in which case the
355buffer switch can continue.
356
357The implementation of the subbuf_start() callback for 'overwrite' mode
358would be very similar:
359
360static int subbuf_start(struct rchan_buf *buf,
361 void *subbuf,
362 void *prev_subbuf,
363 unsigned int prev_padding)
364{
365 if (prev_subbuf)
366 *((unsigned *)prev_subbuf) = prev_padding;
367
368 subbuf_start_reserve(buf, sizeof(unsigned int));
369
370 return 1;
371}
372
373In this case, the relay_buf_full() check is meaningless and the
374callback always returns 1, causing the buffer switch to occur
375unconditionally. It's also meaningless for the client to use the
376relay_subbufs_consumed() function in this mode, as it's never
377consulted.
378
379The default subbuf_start() implementation, used if the client doesn't
380define any callbacks, or doesn't define the subbuf_start() callback,
381implements the simplest possible 'no-overwrite' mode, i.e. it does
382nothing but return 0.
383
384Header information can be reserved at the beginning of each sub-buffer
385by calling the subbuf_start_reserve() helper function from within the
386subbuf_start() callback. This reserved area can be used to store
387whatever information the client wants. In the example above, room is
388reserved in each sub-buffer to store the padding count for that
389sub-buffer. This is filled in for the previous sub-buffer in the
390subbuf_start() implementation; the padding value for the previous
391sub-buffer is passed into the subbuf_start() callback along with a
392pointer to the previous sub-buffer, since the padding value isn't
393known until a sub-buffer is filled. The subbuf_start() callback is
394also called for the first sub-buffer when the channel is opened, to
395give the client a chance to reserve space in it. In this case the
396previous sub-buffer pointer passed into the callback will be NULL, so
397the client should check the value of the prev_subbuf pointer before
398writing into the previous sub-buffer.
399
400Writing to a channel
401--------------------
402
403Kernel clients write data into the current cpu's channel buffer using
404relay_write() or __relay_write(). relay_write() is the main logging
405function - it uses local_irqsave() to protect the buffer and should be
406used if you might be logging from interrupt context. If you know
407you'll never be logging from interrupt context, you can use
408__relay_write(), which only disables preemption. These functions
409don't return a value, so you can't determine whether or not they
410failed - the assumption is that you wouldn't want to check a return
411value in the fast logging path anyway, and that they'll always succeed
412unless the buffer is full and no-overwrite mode is being used, in
413which case you can detect a failed write in the subbuf_start()
414callback by calling the relay_buf_full() helper function.
415
416relay_reserve() is used to reserve a slot in a channel buffer which
417can be written to later. This would typically be used in applications
418that need to write directly into a channel buffer without having to
419stage data in a temporary buffer beforehand. Because the actual write
420may not happen immediately after the slot is reserved, applications
421using relay_reserve() can keep a count of the number of bytes actually
422written, either in space reserved in the sub-buffers themselves or as
423a separate array. See the 'reserve' example in the relay-apps tarball
424at http://relayfs.sourceforge.net for an example of how this can be
425done. Because the write is under control of the client and is
426separated from the reserve, relay_reserve() doesn't protect the buffer
427at all - it's up to the client to provide the appropriate
428synchronization when using relay_reserve().
429
430Closing a channel
431-----------------
432
433The client calls relay_close() when it's finished using the channel.
434The channel and its associated buffers are destroyed when there are no
435longer any references to any of the channel buffers. relay_flush()
436forces a sub-buffer switch on all the channel buffers, and can be used
437to finalize and process the last sub-buffers before the channel is
438closed.
439
440Misc
441----
442
443Some applications may want to keep a channel around and re-use it
444rather than open and close a new channel for each use. relay_reset()
445can be used for this purpose - it resets a channel to its initial
446state without reallocating channel buffer memory or destroying
447existing mappings. It should however only be called when it's safe to
448do so, i.e. when the channel isn't currently being written to.
449
450Finally, there are a couple of utility callbacks that can be used for
451different purposes. buf_mapped() is called whenever a channel buffer
452is mmapped from user space and buf_unmapped() is called when it's
453unmapped. The client can use this notification to trigger actions
454within the kernel application, such as enabling/disabling logging to
455the channel.

2relayfs - a high-speed data relay filesystem
3============================================
4
5relayfs is a filesystem designed to provide an efficient mechanism for
6tools and facilities to relay large and potentially sustained streams
7of data from kernel space to user space.
8
9The main abstraction of relayfs is the 'channel'. A channel consists
10of a set of per-cpu kernel buffers each represented by a file in the
11relayfs filesystem. Kernel clients write into a channel using
12efficient write functions which automatically log to the current cpu's
13channel buffer. User space applications mmap() the per-cpu files and
14retrieve the data as it becomes available.
15
16The format of the data logged into the channel buffers is completely
17up to the relayfs client; relayfs does however provide hooks which
18allow clients to impose some structure on the buffer data. Nor does
19relayfs implement any form of data filtering - this also is left to
20the client. The purpose is to keep relayfs as simple as possible.
21
22This document provides an overview of the relayfs API. The details of
23the function parameters are documented along with the functions in the
24filesystem code - please see that for details.
25
26Semantics
27=========
28
29Each relayfs channel has one buffer per CPU, each buffer has one or
30more sub-buffers. Messages are written to the first sub-buffer until
31it is too full to contain a new message, in which case it it is
32written to the next (if available). Messages are never split across
33sub-buffers. At this point, userspace can be notified so it empties
34the first sub-buffer, while the kernel continues writing to the next.
35
36When notified that a sub-buffer is full, the kernel knows how many
37bytes of it are padding i.e. unused. Userspace can use this knowledge
38to copy only valid data.
39
40After copying it, userspace can notify the kernel that a sub-buffer
41has been consumed.
42
43relayfs can operate in a mode where it will overwrite data not yet
44collected by userspace, and not wait for it to consume it.
45
46relayfs itself does not provide for communication of such data between
47userspace and kernel, allowing the kernel side to remain simple and
48not impose a single interface on userspace. It does provide a set of
49examples and a separate helper though, described below.
50
51klog and relay-apps example code
52================================
53
54relayfs itself is ready to use, but to make things easier, a couple
55simple utility functions and a set of examples are provided.
56
57The relay-apps example tarball, available on the relayfs sourceforge
58site, contains a set of self-contained examples, each consisting of a
59pair of .c files containing boilerplate code for each of the user and
60kernel sides of a relayfs application; combined these two sets of
61boilerplate code provide glue to easily stream data to disk, without
62having to bother with mundane housekeeping chores.
63
64The 'klog debugging functions' patch (klog.patch in the relay-apps
65tarball) provides a couple of high-level logging functions to the
66kernel which allow writing formatted text or raw data to a channel,
67regardless of whether a channel to write into exists or not, or
68whether relayfs is compiled into the kernel or is configured as a
69module. These functions allow you to put unconditional 'trace'
70statements anywhere in the kernel or kernel modules; only when there
71is a 'klog handler' registered will data actually be logged (see the
72klog and kleak examples for details).
73
74It is of course possible to use relayfs from scratch i.e. without
75using any of the relay-apps example code or klog, but you'll have to
76implement communication between userspace and kernel, allowing both to
77convey the state of buffers (full, empty, amount of padding).
78
79klog and the relay-apps examples can be found in the relay-apps
80tarball on http://relayfs.sourceforge.net
81
82
83The relayfs user space API
84==========================
85
86relayfs implements basic file operations for user space access to
87relayfs channel buffer data. Here are the file operations that are
88available and some comments regarding their behavior:
89
90open() enables user to open an _existing_ buffer.
91
92mmap() results in channel buffer being mapped into the caller's
93 memory space. Note that you can't do a partial mmap - you must
94 map the entire file, which is NRBUF * SUBBUFSIZE.
95
96read() read the contents of a channel buffer. The bytes read are
97 'consumed' by the reader i.e. they won't be available again
98 to subsequent reads. If the channel is being used in
99 no-overwrite mode (the default), it can be read at any time
100 even if there's an active kernel writer. If the channel is
101 being used in overwrite mode and there are active channel
102 writers, results may be unpredictable - users should make
103 sure that all logging to the channel has ended before using
104 read() with overwrite mode.
105
106poll() POLLIN/POLLRDNORM/POLLERR supported. User applications are
107 notified when sub-buffer boundaries are crossed.
108
109close() decrements the channel buffer's refcount. When the refcount
110 reaches 0 i.e. when no process or kernel client has the buffer
111 open, the channel buffer is freed.
112
113
114In order for a user application to make use of relayfs files, the
115relayfs filesystem must be mounted. For example,
116
117 mount -t relayfs relayfs /mnt/relay
118
119NOTE: relayfs doesn't need to be mounted for kernel clients to create
120 or use channels - it only needs to be mounted when user space
121 applications need access to the buffer data.
122
123
124The relayfs kernel API
125======================
126
127Here's a summary of the API relayfs provides to in-kernel clients:
128
129
130 channel management functions:
131
132 relay_open(base_filename, parent, subbuf_size, n_subbufs,
133 callbacks)
134 relay_close(chan)
135 relay_flush(chan)
136 relay_reset(chan)
137 relayfs_create_dir(name, parent)
138 relayfs_remove_dir(dentry)
139 relayfs_create_file(name, parent, mode, fops, data)
140 relayfs_remove_file(dentry)
141
142 channel management typically called on instigation of userspace:
143
144 relay_subbufs_consumed(chan, cpu, subbufs_consumed)
145
146 write functions:
147
148 relay_write(chan, data, length)
149 __relay_write(chan, data, length)
150 relay_reserve(chan, length)
151
152 callbacks:
153
154 subbuf_start(buf, subbuf, prev_subbuf, prev_padding)
155 buf_mapped(buf, filp)
156 buf_unmapped(buf, filp)
157 create_buf_file(filename, parent, mode, buf, is_global)
158 remove_buf_file(dentry)
159
160 helper functions:
161
162 relay_buf_full(buf)
163 subbuf_start_reserve(buf, length)
164
165
166Creating a channel
167------------------
168
169relay_open() is used to create a channel, along with its per-cpu
170channel buffers. Each channel buffer will have an associated file
171created for it in the relayfs filesystem, which can be opened and
172mmapped from user space if desired. The files are named
173basename0...basenameN-1 where N is the number of online cpus, and by
174default will be created in the root of the filesystem. If you want a
175directory structure to contain your relayfs files, you can create it
176with relayfs_create_dir() and pass the parent directory to
177relay_open(). Clients are responsible for cleaning up any directory
178structure they create when the channel is closed - use
179relayfs_remove_dir() for that.
180
181The total size of each per-cpu buffer is calculated by multiplying the
182number of sub-buffers by the sub-buffer size passed into relay_open().
183The idea behind sub-buffers is that they're basically an extension of
184double-buffering to N buffers, and they also allow applications to
185easily implement random-access-on-buffer-boundary schemes, which can
186be important for some high-volume applications. The number and size
187of sub-buffers is completely dependent on the application and even for
188the same application, different conditions will warrant different
189values for these parameters at different times. Typically, the right
190values to use are best decided after some experimentation; in general,
191though, it's safe to assume that having only 1 sub-buffer is a bad
192idea - you're guaranteed to either overwrite data or lose events
193depending on the channel mode being used.
194
195Channel 'modes'
196---------------
197
198relayfs channels can be used in either of two modes - 'overwrite' or
199'no-overwrite'. The mode is entirely determined by the implementation
200of the subbuf_start() callback, as described below. In 'overwrite'
201mode, also known as 'flight recorder' mode, writes continuously cycle
202around the buffer and will never fail, but will unconditionally
203overwrite old data regardless of whether it's actually been consumed.
204In no-overwrite mode, writes will fail i.e. data will be lost, if the
205number of unconsumed sub-buffers equals the total number of
206sub-buffers in the channel. It should be clear that if there is no
207consumer or if the consumer can't consume sub-buffers fast enought,
208data will be lost in either case; the only difference is whether data
209is lost from the beginning or the end of a buffer.
210
211As explained above, a relayfs channel is made of up one or more
212per-cpu channel buffers, each implemented as a circular buffer
213subdivided into one or more sub-buffers. Messages are written into
214the current sub-buffer of the channel's current per-cpu buffer via the
215write functions described below. Whenever a message can't fit into
216the current sub-buffer, because there's no room left for it, the
217client is notified via the subbuf_start() callback that a switch to a
218new sub-buffer is about to occur. The client uses this callback to 1)
219initialize the next sub-buffer if appropriate 2) finalize the previous
220sub-buffer if appropriate and 3) return a boolean value indicating
221whether or not to actually go ahead with the sub-buffer switch.
222
223To implement 'no-overwrite' mode, the userspace client would provide
224an implementation of the subbuf_start() callback something like the
225following:
226
227static int subbuf_start(struct rchan_buf *buf,
228 void *subbuf,
229 void *prev_subbuf,
230 unsigned int prev_padding)
231{
232 if (prev_subbuf)
233 *((unsigned *)prev_subbuf) = prev_padding;
234
235 if (relay_buf_full(buf))
236 return 0;
237
238 subbuf_start_reserve(buf, sizeof(unsigned int));
239
240 return 1;
241}
242
243If the current buffer is full i.e. all sub-buffers remain unconsumed,
244the callback returns 0 to indicate that the buffer switch should not
245occur yet i.e. until the consumer has had a chance to read the current
246set of ready sub-buffers. For the relay_buf_full() function to make
247sense, the consumer is reponsible for notifying relayfs when
248sub-buffers have been consumed via relay_subbufs_consumed(). Any
249subsequent attempts to write into the buffer will again invoke the
250subbuf_start() callback with the same parameters; only when the
251consumer has consumed one or more of the ready sub-buffers will
252relay_buf_full() return 0, in which case the buffer switch can
253continue.
254
255The implementation of the subbuf_start() callback for 'overwrite' mode
256would be very similar:
257
258static int subbuf_start(struct rchan_buf *buf,
259 void *subbuf,
260 void *prev_subbuf,
261 unsigned int prev_padding)
262{
263 if (prev_subbuf)
264 *((unsigned *)prev_subbuf) = prev_padding;
265
266 subbuf_start_reserve(buf, sizeof(unsigned int));
267
268 return 1;
269}
270
271In this case, the relay_buf_full() check is meaningless and the
272callback always returns 1, causing the buffer switch to occur
273unconditionally. It's also meaningless for the client to use the
274relay_subbufs_consumed() function in this mode, as it's never
275consulted.
276
277The default subbuf_start() implementation, used if the client doesn't
278define any callbacks, or doesn't define the subbuf_start() callback,
279implements the simplest possible 'no-overwrite' mode i.e. it does
280nothing but return 0.
281
282Header information can be reserved at the beginning of each sub-buffer
283by calling the subbuf_start_reserve() helper function from within the
284subbuf_start() callback. This reserved area can be used to store
285whatever information the client wants. In the example above, room is
286reserved in each sub-buffer to store the padding count for that
287sub-buffer. This is filled in for the previous sub-buffer in the
288subbuf_start() implementation; the padding value for the previous
289sub-buffer is passed into the subbuf_start() callback along with a
290pointer to the previous sub-buffer, since the padding value isn't
291known until a sub-buffer is filled. The subbuf_start() callback is
292also called for the first sub-buffer when the channel is opened, to
293give the client a chance to reserve space in it. In this case the
294previous sub-buffer pointer passed into the callback will be NULL, so
295the client should check the value of the prev_subbuf pointer before
296writing into the previous sub-buffer.
297
298Writing to a channel
299--------------------
300
301kernel clients write data into the current cpu's channel buffer using
302relay_write() or __relay_write(). relay_write() is the main logging
303function - it uses local_irqsave() to protect the buffer and should be
304used if you might be logging from interrupt context. If you know
305you'll never be logging from interrupt context, you can use
306__relay_write(), which only disables preemption. These functions
307don't return a value, so you can't determine whether or not they
308failed - the assumption is that you wouldn't want to check a return
309value in the fast logging path anyway, and that they'll always succeed
310unless the buffer is full and no-overwrite mode is being used, in
311which case you can detect a failed write in the subbuf_start()
312callback by calling the relay_buf_full() helper function.
313
314relay_reserve() is used to reserve a slot in a channel buffer which
315can be written to later. This would typically be used in applications
316that need to write directly into a channel buffer without having to
317stage data in a temporary buffer beforehand. Because the actual write
318may not happen immediately after the slot is reserved, applications
319using relay_reserve() can keep a count of the number of bytes actually
320written, either in space reserved in the sub-buffers themselves or as
321a separate array. See the 'reserve' example in the relay-apps tarball
322at http://relayfs.sourceforge.net for an example of how this can be
323done. Because the write is under control of the client and is
324separated from the reserve, relay_reserve() doesn't protect the buffer
325at all - it's up to the client to provide the appropriate
326synchronization when using relay_reserve().
327
328Closing a channel
329-----------------
330
331The client calls relay_close() when it's finished using the channel.
332The channel and its associated buffers are destroyed when there are no
333longer any references to any of the channel buffers. relay_flush()
334forces a sub-buffer switch on all the channel buffers, and can be used
335to finalize and process the last sub-buffers before the channel is
336closed.
337
338Creating non-relay files
339------------------------
340
341relay_open() automatically creates files in the relayfs filesystem to
342represent the per-cpu kernel buffers; it's often useful for
343applications to be able to create their own files alongside the relay
344files in the relayfs filesystem as well e.g. 'control' files much like
345those created in /proc or debugfs for similar purposes, used to
346communicate control information between the kernel and user sides of a
347relayfs application. For this purpose the relayfs_create_file() and
348relayfs_remove_file() API functions exist. For relayfs_create_file(),
349the caller passes in a set of user-defined file operations to be used
350for the file and an optional void * to a user-specified data item,
351which will be accessible via inode->u.generic_ip (see the relay-apps
352tarball for examples). The file_operations are a required parameter
353to relayfs_create_file() and thus the semantics of these files are
354completely defined by the caller.
355
356See the relay-apps tarball at http://relayfs.sourceforge.net for
357examples of how these non-relay files are meant to be used.
358
359Creating relay files in other filesystems
360-----------------------------------------
361
362By default of course, relay_open() creates relay files in the relayfs
363filesystem. Because relay_file_operations is exported, however, it's
364also possible to create and use relay files in other pseudo-filesytems
365such as debugfs.
366
367For this purpose, two callback functions are provided,
368create_buf_file() and remove_buf_file(). create_buf_file() is called
369once for each per-cpu buffer from relay_open() to allow the client to
370create a file to be used to represent the corresponding buffer; if
371this callback is not defined, the default implementation will create
372and return a file in the relayfs filesystem to represent the buffer.
373The callback should return the dentry of the file created to represent
374the relay buffer. Note that the parent directory passed to
375relay_open() (and passed along to the callback), if specified, must
376exist in the same filesystem the new relay file is created in. If
377create_buf_file() is defined, remove_buf_file() must also be defined;
378it's responsible for deleting the file(s) created in create_buf_file()
379and is called during relay_close().
380
381The create_buf_file() implementation can also be defined in such a way
382as to allow the creation of a single 'global' buffer instead of the
383default per-cpu set. This can be useful for applications interested
384mainly in seeing the relative ordering of system-wide events without
385the need to bother with saving explicit timestamps for the purpose of
386merging/sorting per-cpu files in a postprocessing step.
387
388To have relay_open() create a global buffer, the create_buf_file()
389implementation should set the value of the is_global outparam to a
390non-zero value in addition to creating the file that will be used to
391represent the single buffer. In the case of a global buffer,
392create_buf_file() and remove_buf_file() will be called only once. The
393normal channel-writing functions e.g. relay_write() can still be used
394- writes from any cpu will transparently end up in the global buffer -
395but since it is a global buffer, callers should make sure they use the
396proper locking for such a buffer, either by wrapping writes in a
397spinlock, or by copying a write function from relayfs_fs.h and
398creating a local version that internally does the proper locking.
399
400See the 'exported-relayfile' examples in the relay-apps tarball for
401examples of creating and using relay files in debugfs.
402
403Misc
404----

406Some applications may want to keep a channel around and re-use it
407rather than open and close a new channel for each use. relay_reset()
408can be used for this purpose - it resets a channel to its initial
409state without reallocating channel buffer memory or destroying
410existing mappings. It should however only be called when it's safe to
411do so i.e. when the channel isn't currently being written to.
412
413Finally, there are a couple of utility callbacks that can be used for
414different purposes. buf_mapped() is called whenever a channel buffer
415is mmapped from user space and buf_unmapped() is called when it's
416unmapped. The client can use this notification to trigger actions
417within the kernel application, such as enabling/disabling logging to
418the channel.

51. Fixed a bug in megaraid_init_mbox().
6 Customer reported "garbage in file on x86_64 platform".
7 Root Cause: the driver registered controllers as 64-bit DMA capable
8 for those which are not support it.
9 Fix: Made change in the function inserting identification machanism
10 identifying 64-bit DMA capable controllers.

622. When INQUIRY with EVPD bit set issued to the MegaRAID controller,
63 system memory gets corrupted.
64 Root Cause: MegaRAID F/W handle the INQUIRY with EVPD bit set
65 incorrectly.
66 Fix: MegaRAID F/W has fixed the problem and being process of release,
67 soon. Meanwhile, driver will filter out the request.
68
693. One of member in the data structure of the driver leads unaligne
70 issue on 64-bit platform.
71 Customer reporeted "kernel unaligned access addrss" issue when
72 application communicates with MegaRAID HBA driver.
73 Root Cause: in uioc_t structure, one of member had misaligned and it
74 led system to display the error message.
75 Fix: A patch submitted to community from following folk.

216 * strictly follow the access pattern.
