perf c2c: Fix 'perf c2c record -e list' to show the default events used
When the event is passed as list, the default events should be listed as per 'perf mem record -e list'. Previous behavior is: $ perf c2c record -e list failed: event 'list' not found, use '-e list' to get list of available events Usage: perf c2c record [<options>] [<command>] or: perf c2c record [<options>] -- <command> [<options>] -e, --event <event> event selector. Use 'perf mem record -e list' to list available events $ New behavior: $ perf c2c record -e list ldlat-loads : available ldlat-stores : available v3: is a rebase. v2: addresses review comments by Jiri Olsa. https://lore.kernel.org/lkml/20191127081844.GH32367@krava/ Signed-off-by: Ian Rogers <irogers@google.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lore.kernel.org/lkml/20200507220604.3391-1-irogers@google.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
