2012-07-25perf kvm: Fix bug resolving guest kernel symsDavid Ahern3-0/+15
Guest kernel symbols are not resolved despite passing the information needed to resolve them. e.g., perf kvm --guest --guestmount=/tmp/guest-mount record -a -- sleep 1 perf kvm --guest --guestmount=/tmp/guest-mount report --stdio 36.55% [guest/11399] [unknown] [g] 0xffffffff81600bc8 33.19% [guest/10474] [unknown] [g] 0x00000000c0116e00 30.26% [guest/11094] [unknown] [g] 0xffffffff8100a288 43.69% [guest/10474] [unknown] [g] 0x00000000c0103d90 37.38% [guest/11399] [unknown] [g] 0xffffffff81600bc8 12.24% [guest/11094] [unknown] [g] 0xffffffff810aa91d 6.69% [guest/11094] [unknown] [u] 0x00007fa784d721c3 which is just pathetic. After a maddening 2 days sifting through perf minutia I found it -- id_hdr_size is not initialized for guest machines. This shows up on the report side as random garbage for the cpu and timestamp, e.g., 29816 7310572949125804849 0x1ac0 [0x50]: PERF_RECORD_MMAP ... That messes up the sample sorting such that synthesized guest maps are processed last.

2012-07-25perf kvm: Set name for VM process in guest machineDavid Ahern1-1/+16
COMM events are not generated in the context of a guest machine, so the thread name is never set for the VMM process.

2012-07-02perf bench: Fix confused variable namings and descriptions in mem subsystemHitoshi Mitake3-82/+82
As Namhyung Kim pointed, there are confused namings and descriptions of words "cycle" and "clock" in mem-memset.c and mem-memcpy.c. With the option "-c" (or "--clock", now renamed as "--cycle"), mem subsystem measures cost of memset() and memcpy() with cpu-cycles event. But current mem subsystem source code contains lots of confused variable namings and descriptions with "clock" (e.g. the variable use_clock). This is a very bad style because there is another software event named "cpu-clock". This patch replaces wrong usage of "clock" to "cycle". v2: modified Documentation/perf-bench.txt for the descriptions of --cycle option Signed-off-by: Hitoshi Mitake <h.mitake@gmail.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Link: http://lkml.kernel.org/r/1341236777-18457-1-git-send-email-h.mitake@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2012-07-02perf kvm: Fix regression with guest machine creationDavid Ahern1-1/+1
Commit 743eb868657bdb1b26c7b24077ca21c67c82c777 reworked when the machines were created. Prior to this commit guest machines could be created in perf_event__process_kernel_mmap() while processing kernel MMAP events. This commit assumes that the machines exist by the time perf_session_deliver_event is called (e.g., during processing of build id events) - which is not always correct. One example is the use of default guest args (--guestkallsyms and --guestmodules) for short times where no samples hit within a guest module. For this case no build id is added to the file header. No build id == no machine created. That leads to the next example -- the use of no-buildid (-B) on the record for all perf-kvm invocations. In both cases perf report dies with a SEGFAULT of the form: (gdb) bt 0 0x000000000046dd7b in machine__mmap_name (self=0x0, bf=0x7fffffffbd20 "q\021", size=4096) at util/map.c:715 1 0x0000000000444161 in perf_event__process_kernel_mmap (tool=0x7fffffffdd80, event=0x7ffff7fb4120, machine=0x0) at util/event.c:562 2 0x0000000000444642 in perf_event__process_mmap (tool=0x7fffffffdd80, event=0x7ffff7fb4120, sample=0x7fffffffd210, machine=0x0) at util/event.c:668 3 0x0000000000470e0b in perf_session_deliver_event (session=0x915ca0, event=0x7ffff7fb4120, sample=0x7fffffffd210, tool=0x7fffffffdd80, file_offset=8480) at util/session.c:979 4 0x000000000047032e in flush_sample_queue (s=0x915ca0, tool=0x7fffffffdd80) at util/session.c:679 5 0x0000000000471c8d in __perf_session__process_events (session=0x915ca0, data_offset=400, data_size=150448, file_size=150848, tool= 0x7fffffffdd80) at util/session.c:1363 6 0x0000000000471d42 in perf_session__process_events (self=0x915ca0, tool=0x7fffffffdd80) at util/session.c:1379 7 0x000000000042484a in __cmd_report (rep=0x7fffffffdd80) at builtin-report.c:368 8 0x0000000000425bf1 in cmd_report (argc=0, argv=0x915b00, prefix=0x0) at builtin-report.c:756 9 0x0000000000438505 in __cmd_report (argc=4, argv=0x7fffffffe260) at builtin-kvm.c:84 10 0x000000000043882a in cmd_kvm (argc=4, argv=0x7fffffffe260, prefix=0x0) at builtin-kvm.c:131 11 0x00000000004152cd in run_builtin (p=0x7a54e8, argc=9, argv=0x7fffffffe260) at perf.c:273 12 0x00000000004154c7 in handle_internal_command (argc=9, argv=0x7fffffffe260) at perf.c:345 13 0x0000000000415613 in run_argv (argcp=0x7fffffffe14c, argv=0x7fffffffe140) at perf.c:389 14 0x0000000000415899 in main (argc=9, argv=0x7fffffffe260) at perf.c:487 Fix by allowing the machine to be created in perf_session_deliver_event.

2012-06-27perf report: Delay sample_type checks in pipe modeDavid Ahern1-2/+4
The pipeline: perf record -a -g -o - sleep 5 |perf inject -v -b | perf report -g -i - generates the warning: Selected -g but no callchain data. Did you call 'perf record' without -g? The problem is that the header data is not written to the pipe, so the sample_type has not been available when perf_report__setup_sample_type is called. For pipe mode, record dumps the sample type as part of the synthesized events stream -- perf_event__synthesize_attrs(). Handle this be detecting pipe mode and not doing early sanity checks on sample_type.

2012-06-27perf tools: Stop using a global trace events description listArnaldo Carvalho de Melo15-182/+314
The pevent thing is per perf.data file, so I made it stop being static and become a perf_session member, so tools processing perf.data files use perf_session and _there_ we read the trace events description into session->pevent and then change everywhere to stop using that single global pevent variable and use the per session one. Note that it _doesn't_ fall backs to trace__event_id, as we're not interested at all in what is present in the /sys/kernel/debug/tracing/events in the workstation doing the analysis, just in what is in the perf.data file. This patch also introduces perf_session__set_tracepoints_handlers that is the perf perf.data/session way to associate handlers to tracepoint events by resolving their IDs using the events descriptions stored in a perf.data file. Make 'perf sched' use it.

2012-06-25perf evsel: Fix a build failure on cross compilationNamhyung Kim1-1/+0
The commit c410431cefefd ("perf tools: Reconstruct event with modifiers from perf_event_attr") added the line, but it's broken since it needs to go up 3 directories to get to the kernel root directory, not 2. However host gcc contains /usr/local/include in its search path, so that it can find the perf_event.h in /usr/include. This why we didn't notice the problem yet. But when I tried to cross compile it appears like: CC util/evsel.o util/evsel.c:18:44: error: ../../include/linux/perf_event.h: No such file or directory make: *** [util/evsel.o] Error 1 Looking at the source, it isn't needed at all as evsel.h already included the perf_event.h. So simply remove it would solve the problem.

Example: [root@sandy ~]# perf record -a sleep 3 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.555 MB perf.data (~24236 samples) ] [root@sandy ~]# perf report -s dso,srcline 2>&1 | grep -v ^# | head -5 22.41% [kernel.kallsyms] /home/git/linux/drivers/idle/intel_idle.c:280 4.79% [kernel.kallsyms] /home/git/linux/drivers/cpuidle/cpuidle.c:148 4.78% [kernel.kallsyms] /home/git/linux/arch/x86/include/asm/atomic64_64.h:121 4.49% [kernel.kallsyms] /home/git/linux/kernel/sched/core.c:1690 4.30% [kernel.kallsyms] /home/git/linux/include/linux/seqlock.h:90 [root@sandy ~]# [root@sandy ~]# perf top -U -s dso,symbol,srcline Samples: 1K of event 'cycles', Event count (approx.): 589617389 18.66% [kernel] [k] copy_user_generic_unrolled /home/git/linux/arch/x86/lib/copy_user_64.S:143 7.83% [kernel] [k] clear_page /home/git/linux/arch/x86/lib/clear_page_64.S:39 6.59% [kernel] [k] clear_page /home/git/linux/arch/x86/lib/clear_page_64.S:38 3.66% [kernel] [k] page_fault /home/git/linux/arch/x86/kernel/entry_64.S:1379 3.25% [kernel] [k] clear_page /home/git/linux/arch/x86/lib/clear_page_64.S:40 3.12% [kernel] [k] clear_page /home/git/linux/arch/x86/lib/clear_page_64.S:37 2.74% [kernel] [k] clear_page /home/git/linux/arch/x86/lib/clear_page_64.S:36 2.39% [kernel] [k] clear_page /home/git/linux/arch/x86/lib/clear_page_64.S:43 2.12% [kernel] [k] ioread32 /home/git/linux/lib/iomap.c:90 1.51% [kernel] [k] copy_user_generic_unrolled /home/git/linux/arch/x86/lib/copy_user_64.S:144 1.19% [kernel] [k] copy_user_generic_unrolled /home/git/linux/arch/x86/lib/copy_user_64.S:154 Suggested-by: Andi Kleen <andi@firstfloor.org> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-pdmqbng9twz06jzkbgtuwbp8@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
