2009-11-17Merge branch 'perf/core' into perf/probesIngo Molnar1-0/+2
Resolved merge conflict in tools/perf/Makefile Merge reason: we want to queue up a dependent patch. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-11-16perf buildid-list: New plumbing commandArnaldo Carvalho de Melo1-0/+1
With this we can list the buildids in a perf.data file so that we can pipe them to other, distro specific tools that from the buildids can figure out separate packages (foo-debuginfo) where we can find the matching symtabs so that perf report can do its job. E.g: [acme@doppio linux-2.6-tip]$ perf buildid-list | head -5 8e08b117e5458ad3f85da16d42d0fc5cd21c5869 520c2387a587cc5acfcf881e27dba1caaeab4b1f ec8dd400904ddfcac8b1c343263a790f977159dc 7caedbca5a6d8ab39a7fe44bd28c07d3e14a3f3f 379bb828fd08859dbea73279f04abefabc95a6a3 [acme@doppio linux-2.6-tip]$ perf buildid-list -v | head -5 8e08b117e5458ad3f85da16d42d0fc5cd21c5869 /sbin/init 520c2387a587cc5acfcf881e27dba1caaeab4b1f /lib64/ld-2.10.1.so ec8dd400904ddfcac8b1c343263a790f977159dc /lib64/libc-2.10.1.so 7caedbca5a6d8ab39a7fe44bd28c07d3e14a3f3f /sbin/udevd 379bb828fd08859dbea73279f04abefabc95a6a3 /lib64/libdl-2.10.1.so [acme@doppio linux-2.6-tip]$ Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> LKML-Reference: <1258396365-29217-5-git-send-email-acme@infradead.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-11-10perf bench: Modify command-list.txt for the entry of perf-benchHitoshi Mitake1-0/+1
This patch modifies command-list.txt for the entry of perf-bench. So perf will show 'bench' in command list. Example: % perf usage: perf [--version] [--help] COMMAND [ARGS] The most commonly used perf commands are: annotate Read perf.data (created by perf record) and display annotated code bench General framework for benchmark suites ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ list List all symbolic event types probe Define new dynamic tracepoints record Run a command and record its profile into perf.data report Read perf.data (created by perf record) and display the profile sched Tool to trace/measure scheduler properties (latencies) stat Run a command and gather performance counter statistics timechart Tool to visualize total system behavior during a workload top System profiling tool. trace Read perf.data (created by perf record) and display trace output See 'perf help COMMAND' for more information on a specific command.

2009-09-19perf: Add timechart help text and add timechart to "perf help"Arjan van de Ven1-0/+1
As suggested by Ingo, add a timechart man page help text, as well as add it to the "perf help" overview.

2009-09-13perf: Add 'perf sched' toolIngo Molnar1-0/+2
This turn-key tool allows scheduler measurements to be conducted and the results be displayed numerically. First baby step towards that goal: clone the new command off of perf trace. Fix a few other details along the way: - add (minimal) perf trace documentation - reorder a few places - list perf trace in the mainporcelain list as well as it's a very useful utility.

2009-06-06perf_counter tools: Move from Documentation/perf_counter/ to tools/perf/Ingo Molnar1-0/+10
Several people have suggested that 'perf' has become a full-fledged tool that should be moved out of Documentation/. Move it to the (new) tools/ directory.
