Subject: [PATCH 17/29] perf c2c: Increase the HITM ratio limit for displayed cachelines
Date: Thu, 3 Jan 2019 09:45:57 -0300 [thread overview]
Message-ID: <20190103124609.29672-18-acme@kernel.org> (raw)
In-Reply-To: <20190103124609.29672-1-acme@kernel.org>
From: Jiri Olsa <jolsa@kernel.org>
The cachelines being reported are the ones with percentages all the way
down to 0.05%. That makes for very long output files. Raising that to
0.1%. The user can always specify --show-all if they want all the
cachelines with hits.
