As a side effect, it allows a nice optimisation by only tracking the in-use counters when flipping them on and off, now that we are guaranteed not to have any spurious bit set. * kvm-arm64/pmu/reset-values: KVM: arm64: Remove PMSWINC_EL0 shadow register KVM: arm64: Disabling disabled PMU counters wastes a lot of time KVM: arm64: Drop unnecessary masking of PMU registers KVM: arm64: Narrow PMU sysreg reset values to architectural requirements Signed-off-by: Marc Zyngier --- a4516f32f0e60c26c20f137417e2ec64de0abcbb
