Subject: [PATCH] perf/x86/cstate: Add SAPPHIRERAPIDS_X CPU support
Date: Fri, 15 Apr 2022 18:45:20 +0800 [thread overview]
Message-ID: <20220415104520.2737004-1-rui.zhang@intel.com> (raw)
From the perspective of Intel cstate residency counters,
SAPPHIRERAPIDS_X is the same as ICELAKE_X.
Share the code with it. And update the comments for SAPPHIRERAPIDS_X.
