Merge branch 'kvm-arm64/pmuv3-asahi' into kvmarm/next
* kvm-arm64/pmuv3-asahi: : Support PMUv3 for KVM guests on Apple silicon : : Take advantage of some IMPLEMENTATION DEFINED traps available on Apple : parts to trap-and-emulate the PMUv3 registers on behalf of a KVM guest. : Constrain the vPMU to a cycle counter and single event counter, as the : Apple PMU has events that cannot be counted on every counter. : : There is a small new interface between the ARM PMU driver and KVM, where : the PMU driver owns the PMUv3 -> hardware event mappings. arm64: Enable IMP DEF PMUv3 traps on Apple M* KVM: arm64: Provide 1 event counter on IMPDEF hardware drivers/perf: apple_m1: Provide helper for mapping PMUv3 events KVM: arm64: Remap PMUv3 events onto hardware KVM: arm64: Advertise PMUv3 if IMPDEF traps are present KVM: arm64: Compute synthetic sysreg ESR for Apple PMUv3 traps KVM: arm64: Move PMUVer filtering into KVM code KVM: arm64: Use guard() to cleanup usage of arm_pmus_lock KVM: arm64: Drop kvm_arm_pmu_available static key KVM: arm64: Use a cpucap to determine if system supports FEAT_PMUv3 KVM: arm64: Always support SW_INCR PMU event KVM: arm64: Compute PMCEID from arm_pmu's event bitmaps drivers/perf: apple_m1: Support host/guest event filtering drivers/perf: apple_m1: Refactor event select/filter configuration Signed-off-by: Oliver Upton <oliver.upton@linux.dev>
