With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n sed -i \\\n -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n -e \u0027s/perf_counter/perf_event/g\u0027 \\\n -e \u0027s/nb_counters/nb_events/g\u0027 \\\n -e \u0027s/swcounter/swevent/g\u0027 \\\n -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n $FILES\n\n for N in $(find . -name perf_counter.[ch]); do\n M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n mv $N $M\n done\n\n FILES\u003d$(find . -name perf_event.*)\n\n sed -i \\\n -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n -e \u0027s/COUNTER/EVENT/g\u0027 \\\n -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n -e \u0027s/counter/event/g\u0027 \\\n -e \u0027s/Counter/Event/g\u0027 \\\n $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming. We tried to time this\nchange to the point in time where the amount of pending patches\nis the smallest: the end of the merge window.\n\nNamespace clashes were fixed up in a preparatory patch - and some\nstylistic fallout will be fixed up in a subsequent patch.\n\n( NOTE: \u0027counters\u0027 are still the proper terminology when we deal\n with hardware registers - and these sed scripts are a bit\n over-eager in renaming them. I\u0027ve undone some of that, but\n in case there\u0027s something left where \u0027counter\u0027 would be\n better than \u0027event\u0027 we can undo that on an individual basis\n instead of touching an otherwise nicely automated patch. )\n\nSuggested-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nReviewed-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \"David S.

Doing so adds\nthese new capabilities to this tracepoint:\n\n - zero-copy and per-cpu splice() tracing\n - binary tracing without printf overhead\n - structured logging records exposed under /debug/tracing/events\n - trace events embedded in function tracer output and other plugins\n - user-defined, per tracepoint filter expressions\n ...\n\nCons:\n\n - no dev_t info for the output of plug, unplug_timer and unplug_io events.\n no dev_t info for getrq and sleeprq events if bio \u003d\u003d NULL.\n no dev_t info for rq_abort,...,rq_requeue events if rq-\u003erq_disk \u003d\u003d NULL.\n\n This is mainly because we can\u0027t get the deivce from a request queue.\n But this may change in the future.\n\n - A packet command is converted to a string in TP_assign, not TP_print.\n While blktrace do the convertion just before output.\n\n Since pc requests should be rather rare, this is not a big issue.\n\n - In blktrace, an event can have 2 different print formats, but a TRACE_EVENT\n has a unique format, which means we have some unused data in a trace entry.\n\n The overhead is minimized by using __dynamic_array() instead of __array().\n\nI\u0027ve benchmarked the ioctl blktrace vs the splice based TRACE_EVENT tracing:\n\n dd dd + ioctl blktrace dd + TRACE_EVENT (splice)\n1 7.36s, 42.7 MB/s 7.50s, 42.0 MB/s 7.41s, 42.5 MB/s\n2 7.43s, 42.3 MB/s 7.48s, 42.1 MB/s 7.43s, 42.4 MB/s\n3 7.38s, 42.6 MB/s 7.45s, 42.2 MB/s 7.41s, 42.5 MB/s\n\nSo the overhead of tracing is very small, and no regression when using\nthose trace events vs blktrace.\n\nAnd the binary output of TRACE_EVENT is much smaller than blktrace:\n\n # ls -l -h\n -rw-r--r-- 1 root root 8.8M 06-09 13:24 sda.blktrace.0\n -rw-r--r-- 1 root root 195K 06-09 13:24 sda.blktrace.1\n -rw-r--r-- 1 root root 2.7M 06-09 13:25 trace_splice.out\n\nFollowing are some comparisons between TRACE_EVENT and blktrace:\n\nplug:\n kjournald-480 [000] 303.084981: block_plug: [kjournald]\n kjournald-480 [000] 303.084981: 8,0 P N [kjournald]\n\nunplug_io:\n kblockd/0-118 [000] 300.052973: block_unplug_io: [kblockd/0] 1\n kblockd/0-118 [000] 300.052974: 8,0 U N [kblockd/0] 1\n\nremap:\n kjournald-480 [000] 303.085042: block_remap: 8,0 W 102736992 + 8 \u003c- (8,8) 33384\n kjournald-480 [000] 303.085043: 8,0 A W 102736992 + 8 \u003c- (8,8) 33384\n\nbio_backmerge:\n kjournald-480 [000] 303.085086: block_bio_backmerge: 8,0 W 102737032 + 8 [kjournald]\n kjournald-480 [000] 303.085086: 8,0 M W 102737032 + 8 [kjournald]\n\ngetrq:\n kjournald-480 [000] 303.084974: block_getrq: 8,0 W 102736984 + 8 [kjournald]\n kjournald-480 [000] 303.084975: 8,0 G W 102736984 + 8 [kjournald]\n\n bash-2066 [001] 1072.953770: 8,0 G N [bash]\n bash-2066 [001] 1072.953773: block_getrq: 0,0 N 0 + 0 [bash]\n\nrq_complete:\n konsole-2065 [001] 300.053184: block_rq_complete: 8,0 W () 103669040 + 16 [0]\n konsole-2065 [001] 300.053191: 8,0 C W 103669040 + 16 [0]\n\n ksoftirqd/1-7 [001] 1072.953811: 8,0 C N (5a 00 08 00 00 00 00 00 24 00) [0]\n ksoftirqd/1-7 [001] 1072.953813: block_rq_complete: 0,0 N (5a 00 08 00 00 00 00 00 24 00) 0 + 0 [0]\n\nrq_insert:\n kjournald-480 [000] 303.084985: block_rq_insert: 8,0 W 0 () 102736984 + 8 [kjournald]\n kjournald-480 [000] 303.084986: 8,0 I W 102736984 + 8 [kjournald]\n\nChangelog from v2 -\u003e v3:\n\n- use the newly introduced __dynamic_array().\n\nChangelog from v1 -\u003e v2:\n\n- use __string() instead of __array() to minimize the memory required\n to store hex dump of rq-\u003ecmd().\n\n- support large pc requests.\n\n- add missing blk_fill_rwbs_rq() in block_rq_requeue TRACE_EVENT.\n\n- some cleanups.\n\nSigned-off-by: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nLKML-Reference: \u003c4A2DF669.5070905@cn.fujitsu.com\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" }, { "commit": "918143e8b7d6153d7a83a3f854323407939f4a7e", "tree": "34c0b1434516d146fc3811a6d071b052dd59342b", "parents": [ "64edbc562034f2ec3fce382cb208fab40586d005", "563af16c30ede41eda2d614195d88e07f7c7103d" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Jun 05 16:50:29 2009 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Jun 05 16:50:29 2009 +0200" }, "message": "Merge branch \u0027tip/tracing/ftrace-4\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace into tracing/ftrace\n" }, { "commit": "64edbc562034f2ec3fce382cb208fab40586d005", "tree": "7fbfaaea9467d14a1a6ac5667ce01be5ccb9b635", "parents": [ "43bd1236234cacbc18d1476a9b57e7a306efddf5", "0f6ce3de4ef6ff940308087c49760d068851c1a7" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Jun 04 13:59:26 2009 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Jun 04 13:59:40 2009 +0200" }, "message": "Merge branch \u0027tracing/ftrace\u0027 into tracing/core\n\nMerge reason: this mini-topic had outstanding problems that delayed\n its merge, so it does not fast-forward.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "56d8bd3f0b98972312cad683947ec90b21011199", "tree": "8ed2bb43d0f00923dd81b5b2c19c91b09e3977c6", "parents": [ "048dc50c5e7eada19ebabbad70b7966d14283d41" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Wed Jun 03 14:52:03 2009 +0100" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Wed Jun 03 10:29:48 2009 -0400" }, "message": "tracing: fix multiple use of __print_flags and __print_symbolic\n\nHere is an updated patch to include the extra call to\ntrace_seq_init() as requested.
