Date: Thu, 6 Oct 2022 00:03:12 +0000 From: Sean Christopherson <seanjc@...gle.com> To: Peter Zijlstra <peterz@...radead.org>, Ingo Molnar <mingo@...hat.com>, Arnaldo Carvalho de Melo <acme@...nel.org>, Sean Christopherson <seanjc@...gle.com>, Paolo Bonzini <pbonzini@...hat.com> Cc: Mark Rutland <mark.rutland@....com>, Alexander Shishkin <alexander.shishkin@...ux.intel.com>, Jiri Olsa <jolsa@...nel.org>, Namhyung Kim <namhyung@...nel.org>, linux-perf-users@...r.kernel.org, linux-kernel@...r.kernel.org, kvm@...r.kernel.org, Like Xu <like.xu.linux@...il.com> Subject: [PATCH v5 6/8] KVM: x86: Init vcpu->arch.perf_capabilities in common x86 code Initialize vcpu->arch.perf_capabilities in x86's kvm_arch_vcpu_create() instead of deferring initialization to vendor code. For better or worse, common x86 handles reads and writes to the MSR, and so common x86 should also handle initializing the MSR. No functional change intended.
