From: Vishal Annapurve <vannapurve@google.com>
TDX module virtualizes PMU for TDX VMs [1]. KVM has limited role to play in virtualizing PMU accesses and needs additional enlightenment to support all toggles provided by TDX module.
This series disables PMU virtualization within KVM for TDX VMs, which is a safe bet until the complete set of PMU controls are implemented within KVM.
