Thomas Renninger e853072055 perf timechart: Fix black idle boxes in the title
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.

Thomas Renninger 00e99a49f6 perf tools: Fix time function double declaration with glibc
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.

Arnaldo Carvalho de Melo 9486aa3877 perf tools: Fix 64 bit integer format strings
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.

Arjan van de Ven 2e600d01c1 perf timechart: Improve the visual appearance of scheduler delays
[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.

Arjan van de Ven 39a90a8ef1 perf timechart: Add a power-only mode
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.

Arjan van de Ven 611a546bec 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.

Arjan van de Ven 5094b65545 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).

Arjan van de Ven a92fe7b306 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.

Arjan van de Ven 964a0b3d2b perf utils: Be consistent about minimum text size in the svghelper
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.
