From 39a90a8ef17fe6fbf4b45e46e3c10d3b8b4a3dea Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Thu, 24 Sep 2009 15:40:13 +0200 Subject: perf timechart: Add a power-only mode For doing work on the Linux power management components, I need to make long (30+ seconds) traces. Currently, this then results in a HUGE svg file, with mostly process data that isn't interesting. This patch adds a --power-only mode to perf timechart that only outputs the CPU power section of the SVG; this significantly reduces the size of the SVG file, making even 30+ second traces viewable with inkscape. As a minor tweak for the same effect, the minimum text size is decreased; current inkscape cannot zoom in deep enough to show text this small, but it reduces inkscape compute time.
