Description yunyings intel_group 2024-01-22 15:54:40 UTC 
Commits from mainline kernel v6.8-rc1:
cb4a6ccf3583 perf/x86/intel/uncore: Support Sierra Forest and Grand Ridge
388d76175bd9 perf/x86/intel/uncore: Support IIO free-running counters on GNR
632c4bf6d007 perf/x86/intel/uncore: Support Granite Rapids
b560e0cd882b perf/x86/uncore: Use u64 to replace unsigned for the uncore offsets array
cf35791476fc perf/x86/intel/uncore: Generic uncore_get_uncores and MMIO format of SPR

This enables uncore PMU support for next gen Intel Xeon platforms Granite Rapids(GNR) and Sierra Forest(SRF).

Kernel v6.6 will need to backport commits above to support uncore PMU on GNR/SRF.
