Add core events taken from Section 1.4 "Core Performance Monitor Counters" of the Performance Monitor Counters for AMD Family 1Ah Model 00h-0Fh Processors document available at the link below. This constitutes events which capture information on op dispatch, execution and retirement, branch prediction, L1 and L2 cache activity, TLB activity, etc. Reviewed-by: Ian Rogers <irogers@google.com> Signed-off-by: Sandipan Das <sandipan.das@amd.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ananth Narayan <ananth.narayan@amd.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Ravi Bangoria <ravi.bangoria@amd.com> Cc: Stephane Eranian <eranian@google.com> Link: https://bugzilla.kernel.org/attachment.cgi?id=305974 Link: https://lore.kernel.org/r/668d194241bf0d42dc37f1c5af8131069a0bd82c.1714717230.git.sandipan.das@amd.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
