* perf util: SVG performance improvementsArjan van de Ven2009-09-201-23/+55
| | | | | | | | | | | | | | | | 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.

* perf util: Make the timechart SVG width dynamicArjan van de Ven2009-09-201-10/+20
| | | | | | | | | | | | | | | | | | 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 timechart: Show the duration of scheduler delays in the SVGArjan van de Ven2009-09-201-4/+52
| | | | | | | | | | | | | | | 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 name of the waker/wakee in timechartArjan van de Ven2009-09-201-7/+21
| | | | | | | | | | | | | 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.

* perf utils: Be consistent about minimum text size in the svghelperArjan van de Ven2009-09-191-11/+13
| | | | | | | | | | | | | | | | | Be more consistent in the svghelper about the minimum text size by having a global #define for this. There needs to be a minimum text size in order to keep the size of the SVG file within the reach of what current SVG viewers can cope with.

* perf: Add a SVG helper library fileArjan van de Ven2009-09-191-0/+382
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.
