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.

perf trace: New tool Initially should look loosely like the venerable 'strace' tool, but using the infrastructure in the perf tools to allow tracing extra targets: [acme@sandy linux]$ perf trace --hell Error: unknown option `hell' usage: perf trace <PID> -p, --pid <pid> trace events on existing process id --tid <tid> trace events on existing thread id --all-cpus system-wide collection from all CPUs --cpu <cpu> list of cpus to monitor --no-inherit child tasks do not inherit counters --mmap-pages <n> number of mmap data pages --uid <user> user to profile [acme@sandy linux]$ Those should have the same semantics as when using with 'perf record'. It gets stuck sometimes, but hey, it works sometimes too! In time it should support perf.data based workloads, i.e. it should have a: -o filename Command line option that will produce a perf.data file that can then be used with 'perf trace' or any of the other perf tools (script, report, etc). It will also eventually have the set of functionalities described in the previous 'trace' prototype by Thomas Gleixner: "Announcing a new utility: 'trace'" http://lwn.net/Articles/415728/ Also planned is to have some of the features suggested in the comments of that LWN article.
