From 0a02ad9331dd4db56c29c60db2e99c4daaad8a48 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Fri, 11 Sep 2009 12:12:54 +0200 Subject: perf: Add 'perf sched' tool This turn-key tool allows scheduler measurements to be conducted and the results be displayed numerically. First baby step towards that goal: clone the new command off of perf trace. Fix a few other details along the way: - add (minimal) perf trace documentation - reorder a few places - list perf trace in the mainporcelain list as well as it's a very useful utility.

The user makes a trace of what is going on with > perf record --timechart /usr/bin/some_command and then can turn the output of this into an svg file > perf timechart which then can be viewed with any SVG view; inkscape works well enough for me. The idea behind timechart is to create a "infinitely zoomable" picture; something that has high level information on a 1:1 zoom level, but which exposes more details every time you zoom into a specific area.
