Revision 33636732dcd7cc738a5913bb730d663c6b03c8fb authored by Kan Liang on 12 January 2015, 17:42:21 UTC, committed by Ingo Molnar on 16 January 2015, 08:06:59 UTC
cycles:p and cycles:pp do not work on SLM since commit: 86a04461a99f ("perf/x86: Revamp PEBS event selection") UOPS_RETIRED.ALL is not a PEBS capable event, so it should not be used to count cycle number. Actually SLM calls intel_pebs_aliases_core2() which uses INST_RETIRED.ANY_P to count the number of cycles. It's a PEBS capable event. But inv and cmask must be set to count cycles. Considering SLM allows all events as PEBS with no flags, only INST_RETIRED.ANY_P, inv=1, cmask=16 needs to handled specially.
