    Subject[PATCH 5.10 039/142] KVM: x86/pmu: Fix HW_REF_CPU_CYCLES event pseudo-encoding in intel_arch_events[]
    Date
    From: Like Xu <like.xu@linux.intel.com>

    commit 98dd2f108e448988d91e296173e773b06fb978b8 upstream.

    The HW_REF_CPU_CYCLES event on the fixed counter 2 is pseudo-encoded as
    0x0300 in the intel_perfmon_event_map[]. Correct its usage.

    Fixes: 62079d8a4312 ("KVM: PMU: add proper support for fixed counter 2")
