Description yunyings intel_group 2023-12-05 10:25:04 UTC 
This ticket is created to track the enabling of Granite Rapids (GNR) core PMU support for Anolis kernel devel-5.10, so that end user can access the core PerfMon counters via perf.

Upstream commits(v6.4-rc1):

5a796d5cb5d1 perf/x86/msr: Add Granite Rapids

One extra following bugfix from upstream kernel v6.4, is also needed:
