Subject: [PATCH v5 23/44] KVM: x86/pmu: Move PMU_CAP_{FW_WRITES,LBR_FMT} into msr-index.h header
Date: Wed, 6 Aug 2025 12:56:45 -0700 [thread overview]
Message-ID: <20250806195706.1650976-24-seanjc@google.com> (raw)
In-Reply-To: <20250806195706.1650976-1-seanjc@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.
