Subject: [PATCH v7 026/102] KVM: TDX: Make pmu_intel.c ignore guest TD case
Date: Mon, 27 Jun 2022 14:53:18 -0700	[thread overview]
Message-ID: <d3dff71468be5aa25296fa46d4962c06d8911e57.1656366338.git.isaku.yamahata@intel.com> (raw)
In-Reply-To: <cover.1656366337.git.isaku.yamahata@intel.com>

From: Isaku Yamahata <isaku.yamahata@intel.com>

Because TDX KVM doesn't support PMU yet (it's future work of TDX KVM
support as another patch series) and pmu_intel.c touches vmx specific
structure in vcpu initialization, as workaround add dummy structure to
struct vcpu_tdx and pmu_intel.c can ignore TDX case.
