Eric Auger a6229d1b5c KVM: arm64: pmu: Don't increment SW_INCR if PMCR.E is unset ... commit 3837407c1a upstream. The specification says PMSWINC increments PMEVCNTR<n>_EL1 by 1 if PMEVCNTR<n>_EL0 is enabled and configured to count SW_INCR. For PMEVCNTR<n>_EL0 to be enabled, we need both PMCNTENSET to be set for the corresponding event counter but we also need the PMCR.E bit to be set.
