perf_counter tools: add in basic glue from Git First very raw version at having a central 'perf' command and a list of subcommands: perf top perf stat perf record perf report ... This is done by picking up Git's collection of utility functions, and hacking them to build fine in this new environment. Signed-off-by: Ingo Molnar <mingo@elte.hu>

perf bench: Modify command-list.txt for the entry of perf-bench 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.

perf buildid-cache: Add new command to manage build-id cache For now it just has operations to examine a given file, find its build-id and add or remove it to/from the cache. Useful, for instance, when adding binaries sent together with a perf.data file, so that we can add them to the cache and have the tools find it when resolving symbols. It'll also manage the size of the cache like 'ccache' does.

perf buildid-list: New plumbing command 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>

For volatile environments, stay tuned for the next perf tool feature: a buildid cache populated by 'perf record', managed by 'perf buildid-cache' a-la ccache, and used by all the report tools.

perf lock: Fix and add misc documentally things I've forgot to add 'perf lock' line to command-list.txt, so users of perf could not find perf lock when they type 'perf'. Fixing command-list.txt requires document (tools/perf/Documentation/perf-lock.txt). But perf lock is too much "under construction" to write a stable document, so this is something like pseudo document for now. And I wrote description of perf lock at help section of CONFIG_LOCK_STAT, this will navigate users of lock trace events.
