Add core events taken from Section 2.1.15.4 "Core Performance Monitor Counters" in the Processor Programming Reference (PPR) for AMD Family 19h Model 11h Revision B1 processors. This constitutes events which capture op dispatch, execution and retirement, branch prediction, L1 and L2 cache activity, TLB activity, etc. Signed-off-by: Sandipan Das <sandipan.das@amd.com> Acked-by: Ian Rogers <irogers@google.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: Jirka Hladky <jhladky@redhat.com> 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://lore.kernel.org/r/20221214082652.419965-2-sandipan.das@amd.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
