From: Jiri Olsa Date: Tue, 11 Oct 2016 11:52:05 +0000 (+0200) Subject: perf c2c report: Add --show-all option X-Git-Tag: Ubuntu-5.10.0-12.13~11358^2~13^2 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=af09b2d35e18f1a377aaa2bc4e5ba4abb98a1088;p=mirror_ubuntu-hirsute-kernel.git perf c2c report: Add --show-all option Normally we limit the main list to contain only entries with HITM % value > 0.0005, but it might be useful to display all captured entries. Adding --show-all option for that.
