[PATCH 5.17 035/772] perf/x86/intel: Fix event constraints for ICL
From: Greg Kroah-Hartman
Date: Tue Jun 07 2022 - 16:24:34 EST
From: Kan Liang <kan.liang@xxxxxxxxxxxxxxx>
commit 86dca369075b3e310c3c0adb0f81e513c562b5e4 upstream.
According to the latest event list, the event encoding 0x55
INST_DECODED.DECODERS and 0x56 UOPS_DECODED.DEC0 are only available on
the first 4 counters. Add them into the event constraints table.
