From: Julien Desfossez Date: Thu, 19 Apr 2012 22:19:10 +0000 (-0400) Subject: New preference panel for CPU X-Git-Tag: v0.2~26 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=3b15348ccad727f0d6232af738efa96b20ebc56a;p=lttngtop.git New preference panel for CPU It allows to switch the sorting by CPU%, PID or TID, it is kind of useless for CPUTop, but the same design will applied in the other views and will be useful.
