Subject: [PATCH 4.14 08/30] KVM: x86/pmu: Fix HW_REF_CPU_CYCLES event pseudo-encoding in intel_arch_events[]
Date: Tue,  2 Feb 2021 14:38:49 +0100	[thread overview]
Message-ID: <20210202132942.472625445@linuxfoundation.org> (raw)
In-Reply-To: <20210202132942.138623851@linuxfoundation.org>

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")
