Subject: [PATCH V6 23/25] perf/x86/msr: Add Alder Lake CPU support
Date: Mon, 12 Apr 2021 07:31:03 -0700	[thread overview]
Message-ID: <1618237865-33448-24-git-send-email-kan.liang@linux.intel.com> (raw)
In-Reply-To: <1618237865-33448-1-git-send-email-kan.liang@linux.intel.com>

From: Kan Liang <kan.liang@linux.intel.com>

PPERF and SMI_COUNT MSRs are also supported on Alder Lake.

The External Design Specification (EDS) is not published yet. It comes
from an authoritative internal source.

The patch has been tested on real hardware.
