[PATCH] perf/x86/intel: Fix pebs event constraints for ADL
From: kan . liang
Date: Thu Aug 18 2022 - 14:45:33 EST
From: Kan Liang <kan.liang@xxxxxxxxxxxxxxx>
According to the latest event list, the LOAD_LATENCY PEBS event only
works on the GP counter 0 and 1 for ADL and RPL.
Update the pebs event constraints table.
Fixes: f83d2f91d259 ("perf/x86/intel: Add Alder Lake Hybrid support")
