Subject: [PATCH v5 1/6] KVM: selftests: Add x86 properties for Intel PMU in processor.h
Date: Thu, 20 Jul 2023 19:47:09 +0800 [thread overview]
Message-ID: <20230720114714.34079-2-cloudliang@tencent.com> (raw)
In-Reply-To: <20230720114714.34079-1-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.
