[PATCH 3/3] perf/x86/cstate: Add Granite Rapids support

From: kan . liang
Date: Tue Mar 14 2023 - 13:00:54 EST


From: Artem Bityutskiy <artem.bityutskiy@xxxxxxxxxxxxxxx>

Granite Rapids Xeon is successor or Emerald Rapids Xeon, and it will use
the same C-state residency counters as Emerald Rapids (and previous
Xeons, all the way back to Ice Lake Xeon).

Add Granite Rapids Xeon support.
