Subject: [PATCH V4 05/14] perf/x86/intel: Fix the name of perf capabilities for perf METRICS
Date: Mon, 16 Sep 2019 06:41:19 -0700 [thread overview]
Message-ID: <20190916134128.18120-6-kan.liang@linux.intel.com> (raw)
In-Reply-To: <20190916134128.18120-1-kan.liang@linux.intel.com>
From: Kan Liang <kan.liang@linux.intel.com>
Bit 15 of PERF_CAPABILITIES MSR indicates this architecture provides
built in support for perf METRICS. The perf METRICS is not a PEBS
feature.
Rename pebs_metrics_available perf_metrics.
No one use the bit in current code. The following patch will use it.
