perf timechart: Fix black idle boxes in the title

2011-02-28T07:56:14Z

This fix is needed for eye of gnome and firefox svg viewers. Only Inkscape can handle the broken case. Compare with the other svg_legenda_box declarations, looks like a typo slipped in at this place.

perf tools: Fix time function double declaration with glibc

2011-01-22T21:53:00Z

It's enough to include the local "debug.h" file to trigger it. man time reveals this is already declared in glibc: time - get time in seconds -> rename the variable.

perf tools: Fix 64 bit integer format strings

2011-01-23T01:41:57Z

Using %L[uxd] has issues in some architectures, like on ppc64. Fix it by making our 64 bit integers typedefs of stdint.h types and using PRI[ux]64 like, for instance, git does. Reported by Denis Kirjanov that provided a patch for one case, I went and changed all cases.

perf timechart: Improve the visual appearance of scheduler delays

2009-10-20T01:39:21Z

[from KS feedback] Currently, scheduler delays are shown in a mostly transparent, light yellow color. This color is rather hard to see on several screens, especially projectors. This patch changes the color of the scheduler delays to be a much more "hard" yellow that survived the kernel summit projector.

perf timechart: Add a power-only mode

2009-10-01T07:26:40Z

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.

perf util: SVG performance improvements

2009-09-20T17:37:36Z

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 dynamic

2009-09-20T17:37:35Z

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 SVG

2009-09-20T17:37:35Z

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 timechart

2009-09-20T17:37:34Z

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 svghelper

2009-09-19T16:57:52Z

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.
