Subject: [PATCH v2] perf/x86/intel/uncore: Use boot_cpu_data.logical_proc_id as the pkg id
Date: Thu, 20 Sep 2018 21:07:46 -0400 [thread overview]
Message-ID: <20180921010746.32118-1-msys.mizuma@gmail.com> (raw)
From: Masayoshi Mizuma <m.mizuma@jp.fujitsu.com>
Physical package id 0 is not always exists. We should use
boot_cpu_data.logical_proc_id directly as the pkg id here.
