Subject: [PATCH 05/10] perf/x86/intel/domain: Add new domain type for die
Date: Tue, 19 Feb 2019 12:00:06 -0800 [thread overview]
Message-ID: <1550606411-5313-6-git-send-email-kan.liang@linux.intel.com> (raw)
In-Reply-To: <1550606411-5313-1-git-send-email-kan.liang@linux.intel.com>
From: Kan Liang <kan.liang@linux.intel.com>
Starts from CLX-AP, some uncore and RAPL counters are die scope.
Add a new domain type DIE_DOMAIN for die scope counters.
To distinguish different die among package, unique die id is used as
domain id.
