Subject: [PATCH v4 18/38] KVM: x86/pmu: Move PMU_CAP_{FW_WRITES,LBR_FMT} into msr-index.h header
Date: Mon, 24 Mar 2025 17:30:58 +0000	[thread overview]
Message-ID: <20250324173121.1275209-19-mizhang@google.com> (raw)
In-Reply-To: <20250324173121.1275209-1-mizhang@google.com>

From: Dapeng Mi <dapeng1.mi@linux.intel.com>

Move PMU_CAP_{FW_WRITES,LBR_FMT} into msr-index.h and rename them with
PERF_CAP prefix to keep consistent with other perf capabilities macros.

No functional change intended.
