Subject: [PATCH 13/19] perf metric: Add cache_miss_cycles to metric parse test
Date: Wed, 29 Jul 2020 11:19:02 +0200	[thread overview]
Message-ID: <20200729091908.1378911-14-jolsa@kernel.org> (raw)
In-Reply-To: <20200729091908.1378911-1-jolsa@kernel.org>

Adding test that compute metric with other metrics in it.

  cache_miss_cycles = metric:dcache_miss_cpi + metric:icache_miss_cycles
