Marc Zyngier 725ce66979 KVM: arm64: pmu: Set the CHAINED attribute before creating the in-kernel event ... The current convention for KVM to request a chained event from the host PMU is to set bit[0] in attr.config1 (PERF_ATTR_CFG1_KVM_PMU_CHAINED). But as it turns out, this bit gets set *after* we create the kernel event that backs our virtual counter, meaning that we never get a 64bit counter. Moving the setting to an earlier point solves the problem.
