Subject: [PATCH v6 1/6] KVM: selftests: Add x86 properties for Intel PMU in processor.h
Date:   Thu, 10 Aug 2023 17:09:40 +0800
Message-Id: <20230810090945.16053-2-cloudliang@tencent.com>

From: Jinrong Liang <cloudliang@tencent.com>

Add x86 properties for Intel PMU so that tests don't have to manually
retrieve the correct CPUID leaf+register, and so that the resulting code
is self-documenting.
