Subject: [PATCH V3 1/5] perf cpumap: Retrieve die id information
Date: Tue, 4 Jun 2019 15:50:40 -0700 [thread overview]
Message-ID: <1559688644-106558-1-git-send-email-kan.liang@linux.intel.com> (raw)
From: Kan Liang <kan.liang@linux.intel.com>
There is no function to retrieve die id information of a given CPU.
Add cpu_map__get_die_id() to retrieve die id information.
Signed-off-by: Kan Liang <kan.liang@linux.intel.com>
