Subject: [PATCH 1/2] perf/x86/intel: Fix rtm_abort_event encoding on Ice Lake
Date: Wed, 25 Nov 2020 13:37:19 -0800 [thread overview]
Message-ID: <20201125213720.15692-1-kan.liang@linux.intel.com> (raw)
From: Kan Liang <kan.liang@linux.intel.com>
According to the event list from icelake_core_v1.09.json, the encoding
of the RTM_RETIRED.ABORTED event on Ice Lake should be,
"EventCode": "0xc9",
"UMask": "0x04",
"EventName": "RTM_RETIRED.ABORTED",
Correct the wrong encoding.
Fixes: 6017608936c1 ("perf/x86/intel: Add Icelake support")
