Subject: [PATCH 14/14] perf tests: Add parse metric test for frontend metric
Date: Mon, 25 May 2020 00:42:19 +0200 [thread overview]
Message-ID: <20200524224219.234847-15-jolsa@kernel.org> (raw)
In-Reply-To: <20200524224219.234847-1-jolsa@kernel.org>
Adding new metri test for frontend metric. It's stolen
from x86 pmu events.
