Subject: [PATCH] perf timechart: Show the name of the waker/wakee in timechart
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.

Subject: [PATCH] perf timechart: Show the duration of scheduler delays in the SVG
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.

perf timechart: Show the duration of scheduler delays in the SVG
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.

Subject: [PATCH] perf util: Make the timechart SVG width dynamic
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).

perf util: SVG performance improvements
Tweak the output SVG to increase performance in SVG viewers by
limiting the different types of font sizes and by smarter
transformations on the text.
At least with Inkscape this gives a notable performance improvement
during zoom and scrolling.
