![]() Programming PMU events in the host that count during guest execution is
a feature supported by perf, e.g.
perf stat -e cpu_cycles:G ./lkvm run
While this works for VHE, the guest/host event bitmaps are not carried
through to the hypervisor in the nVHE configuration. Make
kvm_pmu_update_vcpu_events() conditional on whether or not _hardware_
supports PMUv3 rather than if the vCPU as vPMU enabled.
