Subject: [PATCH v2 4/4] perf tests: Fix 'Convert perf time to TSC' on core-only system
Date: Thu, 8 Jul 2021 09:37:01 +0800 [thread overview]
Message-ID: <20210708013701.20347-5-yao.jin@linux.intel.com> (raw)
In-Reply-To: <20210708013701.20347-1-yao.jin@linux.intel.com>
If the atom CPUs are offlined, the 'cpu_atom' is not valid.
We don't need the test case for 'cpu_atom'.
