Subject: [PATCH 0/3] KVM: arm64: PMU fixes for nVHE, protected mode
Date: Tue, 5 Mar 2024 18:48:37 +0000 [thread overview]
Message-ID: <20240305184840.636212-1-oliver.upton@linux.dev> (raw)
Series to address a couple of issues I've hit using the nVHE / protected
mode configuration:
- Host-programmed PMU events that run during guest execution do not
work if the VM doesn't have a vPMU.
- PMU events do not work at all for non-protected VMs on the
protected-mode hypervisor

KVM: arm64: pkvm: Actually enable/disable PMU events when running vCPU
KVM: arm64: Fix host-programmed guest events in nVHE
KVM: arm64: Do not disable preemption in kvm_vcpu_pmu_restore_guest()
