Subject: [PATCH v4 1/6] KVM: selftests: Add macros for fixed counters in processor.h
Date: Mon, 17 Jul 2023 14:23:38 +0800	[thread overview]
Message-ID: <20230717062343.3743-2-cloudliang@tencent.com> (raw)
In-Reply-To: <20230717062343.3743-1-cloudliang@tencent.com>

From: Jinrong Liang <cloudliang@tencent.com>

Add x86 properties for the number of PMU fixed counters and the bitmask
that allows for "discontiguous" fixed counters so that tests don't have
to manually retrieve the correct CPUID leaf+register, and so that the
resulting code is self-documenting.
