Subject: [PATCH v3 00/14] KVM: arm64: FEAT_PMUv3 on Apple hardware
Date: Wed, 5 Mar 2025 12:26:27 -0800 [thread overview]
Message-ID: <20250305202641.428114-1-oliver.upton@linux.dev> (raw)
Hopefully close to the last spin, this time addressing Marc's comments
on v2.
Full details found in the v1 cover letter.
v1: https://lore.kernel.org/kvmarm/20241217212048.3709204-1-oliver.upton@linux.dev/
v2: https://lore.kernel.org/kvmarm/20250203183111.191519-1-oliver.upton@linux.dev/
v2 -> v3:
- Reorder and restructure patches to include map_pmuv3_event()
definition w/ KVM usage.
- Disallow events that lack a valid PMUv3 -> HW mapping
- Various minor fixes/typos
Oliver Upton (14):
drivers/perf: apple_m1: Refactor event select/filter configuration
drivers/perf: apple_m1: Support host/guest event filtering
KVM: arm64: Compute PMCEID from arm_pmu's event bitmaps
KVM: arm64: Always support SW_INCR PMU event
KVM: arm64: Use a cpucap to determine if system supports FEAT_PMUv3
KVM: arm64: Drop kvm_arm_pmu_available static key
KVM: arm64: Use guard() to cleanup usage of arm_pmus_lock
KVM: arm64: Move PMUVer filtering into KVM code
KVM: arm64: Compute synthetic sysreg ESR for Apple PMUv3 traps
KVM: arm64: Advertise PMUv3 if IMPDEF traps are present
KVM: arm64: Remap PMUv3 events onto hardware
drivers/perf: apple_m1: Provide helper for mapping PMUv3 events
KVM: arm64: Provide 1 event counter on IMPDEF hardware
arm64: Enable IMP DEF PMUv3 traps on Apple M*
