Subject: [PATCH V6 05/14] perf/x86/intel: Fix the name of perf METRICS
Date: Fri, 17 Jul 2020 07:05:45 -0700	[thread overview]
Message-ID: <20200717140554.22863-6-kan.liang@linux.intel.com> (raw)
In-Reply-To: <20200717140554.22863-1-kan.liang@linux.intel.com>

From: Kan Liang <kan.liang@linux.intel.com>

Bit 15 of the PERF_CAPABILITIES MSR indicates that the perf METRICS
feature is supported. The perf METRICS is not a PEBS feature.

Rename pebs_metrics_available perf_metrics.

The bit is not used in the current code. It will be used in a later
patch.
