Just checking, in a heterogeneous setup we still want to keep
these 2 calls per-vCPU, right?
if (kvm_check_extension(cs->kvm_state, KVM_CAP_ARM_PSCI_0_2)) {
cpu->psci_version = QEMU_PSCI_VERSION_0_2;
cpu->kvm_init_features[0] |= 1 << KVM_ARM_VCPU_PSCI_0_2;
}
if (!kvm_check_extension(cs->kvm_state, KVM_CAP_ARM_PMU_V3)) {
cpu->has_pmu = false;
}
