2009-09-24	perf tools: Protect header files with a consistent style	John Kacur	1	-3/+3

2009-09-20	perf util: Make the timechart SVG width dynamic	Arjan van de Ven	1	-2/+4
	This patch adds a command line option for timechart that allows the user to specify the width of the SVG file. This patch also makes sure that each second of recording has at least 200 units (pixels at 96 DPI) of width. This impacts recordings longer than 5 seconds; recordings shorter than 5 second will scale up to have a width of 1000 units for the whole recording (as before).

2009-09-20	perf timechart: Show the duration of scheduler delays in the SVG	Arjan van de Ven	1	-1/+2
	Given that scheduler latencies are the hot thing nowadays, show the duration of said latencies in the SVG in text form. In addition, if the latency is more than 10 msec, pick a brighter yellow color as a way to point these long delays out.

2009-09-20	perf timechart: Show the name of the waker/wakee in timechart	Arjan van de Ven	1	-1/+1
	Timechart currently shows thin green lines for sending or receiving wakeups. This patch also prints (in a very small font) the name of the process that is being woken/wakes up this process.

2009-09-19	perf: Add a SVG helper library file	Arjan van de Ven	1	-0/+25
	The timechart tool writes out SVG format output; this patch adds a set of helper functions to abstract dealing with SVG from the core timechart code.
