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 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 tools: Do not show trace command if it's not compiled in The trace command still appears in help message when you run simple 'perf' command. It's because the generate-cmdlist.sh does not care about the HAVE_LIBAUDIT_SUPPORT dependency of trace command and puts it into generated common_cmds array. Wrapping trace command under HAVE_LIBAUDIT_SUPPORT dependency, which will exclude it from common_cmds array if HAVE_LIBAUDIT_SUPPORT is not set.

perf daemon: Add daemon command Add a daemon skeleton with a minimal base (non) functionality, covering various setup in start command. Add an initial perf-daemon.txt with basic info. This is in response to pople asking for the possibility to be able run record long running sessions on the background. The patchset that starts with this adds support to configure and run record sessions on background via new 'perf daemon' command. This is useful for being able to use perf as a flight recorder that one can interact with asking for events to be enabled or disabled, added or removed, etc. Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexei Budankov <abudankov@huawei.com> Cc: Arnaldo Carvalho de Melo <acme@kernel.org> Cc: Ian Rogers <irogers@google.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: https://lore.kernel.org/r/20210208200908.1019149-2-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
