2011-02-17perf: make perf stat print user provided full event namesStephane Eranian3-0/+18
This patch changes the way perf stat prints event names at the end of a run. Until now, it was trying to reconstruct the event name from its encoding. The problem is that it would only print generic events without their modifiers (u, k, pp). This patch saves the event name as passed by the user in the evsel struct and uses it to print the final event name. This would also work in case perf is linked with a library (such as libpfm4) which provides full PMU event tables. $ perf stat -e cycles:u,cycles:k date Wed Feb 16 14:58:52 CET 2011 Performance counter stats for 'date': 568600 cycles:u 2779715 cycles:k 0.001908182 seconds time elapsed Cc: Arun Sharma <[email protected]> Cc: David S.

2011-02-16perf probe: Show filename which contains target functionMasami Hiramatsu1-1/+1
Show filename which contains a target function with the function name on "--lines" mode, because perf-probe just shows the first function even if there are many same-name functions. Originally adopted by Franck Bui-Huu's patch which shows file name instead of function name. I've just modified it to show both of function name and file name, because of completeness of output. E.g.) $ perf probe -L t_show <t_show@/home/mhiramat/ksrc/linux-2.6-tip/kernel/trace/ftrace.c:0> 0 static int t_show(struct seq_file *m, void *v) 1 { 2 struct ftrace_iterator *iter = m->private; ... $ perf probe -L t_show@trace/trace.c <t_show@/home/mhiramat/ksrc/linux-2.6-tip/kernel/trace/trace.c:0> 0 static int t_show(struct seq_file *m, void *v) 1 { struct tracer *t = v; ...

2011-02-16perf tool: Add cgroup supportStephane Eranian9-10/+276
This patch adds the ability to filter monitoring based on container groups (cgroups) for both perf stat and perf record. It is possible to monitor multiple cgroup in parallel. There is one cgroup per event. The cgroups to monitor are passed via a new -G option followed by a comma separated list of cgroup names. The cgroup filesystem has to be mounted. Given a cgroup name, the perf tool finds the corresponding directory in the cgroup filesystem and opens it. It then passes that file descriptor to the kernel. Example: $ perf stat -B -a -e cycles:u,cycles:u,cycles:u -G test1,,test2 -- sleep 1 Performance counter stats for 'sleep 1': 2,368,667,414 cycles test1 2,369,661,459 cycles <not counted> cycles test2 1.001856890 seconds time elapsed Signed-off-by: Stephane Eranian <[email protected]> Signed-off-by: Peter Zijlstra <[email protected]> LKML-Reference: <[email protected]> Signed-off-by: Ingo Molnar <[email protected]>

2011-02-10perf tools: Fix thread_map event synthesizing in top and recordArnaldo Carvalho de Melo4-10/+20
Jeff Moyer reported these messages: Warning: ... trying to fall back to cpu-clock-ticks couldn't open /proc/-1/status couldn't open /proc/-1/maps [ls output] [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.008 MB perf.data (~363 samples) ] That lead me and David Ahern to see that something was fishy on the thread synthesizing routines, at least for the case where the workload is started from 'perf record', as -1 is the default for target_tid in 'perf record --tid' parameter, so somehow we were trying to synthesize the PERF_RECORD_MMAP and PERF_RECORD_COMM events for the thread -1, a bug. So I investigated this and noticed that when we introduced support for recording a process and its threads using --pid some bugs were introduced and that the way to fix it was to instead of passing the target_tid to the event synthesizing routines we should better pass the thread_map that has the list of threads for a --pid or just the single thread for a --tid.

GCC 4.6.0 in Fedora rawhide turned up some compile errors in tools/perf due to the -Werror=unused-but-set-variable flag. I've gone through and annotated some of the assignments that had side effects (ie: return value from a function) with the __used annotation, and in some cases, just removed unused code. In a few cases, we were assigning something useful, but not using it in later parts of the function. kyle@dreadnought:~/src% gcc --version gcc (GCC) 4.6.0 20110122 (Red Hat 4.6.0-0.3) Cc: Ingo Molnar <[email protected]> LKML-Reference: <[email protected]> Signed-off-by: Kyle McMartin <[email protected]> [ committer note: Fixed up the annotation fixes, as that code moved recently ] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>

2011-02-05perf annotate: Move annotate functions to util/Arnaldo Carvalho de Melo8-503/+578
They will be used by perf top, so that we have just one set of routines to do annotation. Rename "struct sym_priv" to "struct annotation", etc, to clarify this code a bit. Rename "struct sym_ext" to "struct source_line", to give it a meaningful name, that clarifies that it is a the result of an addr2line call, that is sorted by percentage one particular source code line appeared in the annotation. And since we're moving things around also rename 'sym_hist->ip' to 'sym_hist->addr' as we want to do data structure annotation at some point.
