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": "f57a8a1911342265e7acdc190333c4e9235a6632", "tree": "db7aecf9dc26311068a48da77022e0377bf5d3d6", "parents": [ "1f8a6a10fb9437eac3f516ea4324a19087872f30" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Fri Jun 05 14:11:30 2009 -0400" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Tue Jun 09 12:33:30 2009 -0400" }, "message": "ring-buffer: fix ret in rb_add_time_stamp\n\nThe update of ret got mistakenly added to the if statement of\nrb_try_to_discard.

8e3747c1 (\"perf_counter: Change data head from u32 to u64\")\nchanged the type of \u0027head\u0027 in struct perf_mmap_data from atomic_t\nto atomic_long_t, but missed converting one use of atomic_read on\nit to atomic_long_read. The effect of using atomic_read rather than\natomic_long_read on powerpc (and other big-endian architectures) is\nthat we get the high half of the 64-bit quantity, resulting in the\ncmpxchg retry loop in perf_output_begin spinning forever as soon as\ndata-\u003ehead becomes non-zero. On little-endian architectures such as\nx86 we would get the low half, resulting in a lockup once data-\u003ehead\nbecomes greater than 4G.\n\nThis fixes it by using atomic_long_read rather than atomic_read.\n\n[ Impact: fix perfcounter lockup on PowerPC / big-endian systems ]\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c18984.33964.21541.743096@cargo.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" } ], "next": "edaba2c5334492f82d39ec35637c6dea5176a977" }
