perf timechart: Implement IO mode

2014-07-09T22:22:54Z

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).

tools: Consolidate types.h

2014-05-01T19:22:39Z

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.

perf timechart: Add backtrace support

2013-11-27T17:58:37Z

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.

perf timechart: Group figures and add title with details

2013-11-27T17:58:37Z

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.

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).
