Subject: [PATCH V3 5/8] perf/x86/intel: Export TopDown events for Icelake
Date: Wed, 24 Jul 2019 10:17:50 -0700 [thread overview]
Message-ID: <20190724171753.8087-6-kan.liang@linux.intel.com> (raw)
In-Reply-To: <20190724171753.8087-1-kan.liang@linux.intel.com>
From: Kan Liang <kan.liang@linux.intel.com>
Export new TopDown metrics events for perf that map to the sub metrics
in the metrics register, and another for the new slots fixed counter.
This makes the new fixed counters in Icelake visible to the perf
user tools.
