2014-07-10perf timechart: Implement IO modeStanislav Fomichev1-1/+5
Currently, timechart records only scheduler and CPU events (task switches, running times, CPU power states, etc); this commit adds IO mode which makes it possible to record IO (disk, network) activity. In this mode perf timechart will generate SVG with IO charts (writes, reads, tx, rx, polls).

2014-05-01tools: Consolidate types.hBorislav Petkov1-1/+1
Combine all definitions into a common tools/include/linux/types.h and kill the wild growth elsewhere. Move DECLARE_BITMAP to its proper bitmap.h header.

2013-11-27perf timechart: Add backtrace supportStanislav Fomichev1-6/+6
Add -g flag to `perf timechart record` which saves callchain info in the perf.data. When generating SVG, add backtrace information to the figure details, so now it's possible to see which code path woke up the task and why some task went to sleep.

2013-11-27perf timechart: Group figures and add title with detailsStanislav Fomichev1-2/+3
Add titles to figures so we can run SVG interactively in Firefox and check event details in the tooltips. This also aids exploring SVG with Inkscape because when user clicks on one part of logical figure, all parts are selected. It's also possible to read titles with Inkscape in the object details.

2009-09-20perf util: Make the timechart SVG width dynamicArjan van de Ven1-2/+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).

2009-09-20perf timechart: Show the duration of scheduler delays in the SVGArjan van de Ven1-1/+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.

2009-09-20perf timechart: Show the name of the waker/wakee in timechartArjan van de Ven1-1/+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.

2009-09-19perf: Add a SVG helper library fileArjan van de Ven1-0/+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.
