Add kernel AUX area sampling definitions, which brings perf_event.h into line with the kernel version. New sample type PERF_SAMPLE_AUX requests a sample of the AUX area buffer. New perf_event_attr member 'aux_sample_size' specifies the desired size of the sample. Also add support for parsing samples containing AUX area data i.e. PERF_SAMPLE_AUX. Committer notes: I squashed the first two patches in this series to avoid breaking automatic bisection, i.e. after applying only the original first patch in this series we would have: # perf test -v parsing 26: Sample parsing : --- start --- test child forked, pid 17018 sample format has changed, some new PERF_SAMPLE_ bit was introduced - test needs updating test child finished with -1 ---- end ---- Sample parsing: FAILED! # With the two paches combined: # perf test parsing 26: Sample parsing : Ok # Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lore.kernel.org/lkml/20191115124225.5247-3-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
