Subject: [PATCH 13/19] perf metric: Add cache_miss_cycles to metric parse test
Date: Sun, 19 Jul 2020 20:13:14 +0200 [thread overview]
Message-ID: <20200719181320.785305-14-jolsa@kernel.org> (raw)
In-Reply-To: <20200719181320.785305-1-jolsa@kernel.org>
Adding test that compute metric with other metrics in it.
cache_miss_cycles = metric:dcache_miss_cpi + metric:icache_miss_cycles
Acked-by: Ian Rogers <irogers@google.com>
