perf timechart: Conditionally update start_time on fork

2014-07-09T22:22:54+00:00

We don't need to overwrite current task start_time on fork, so update it
only if it's zero.

perf timechart: Implement IO mode

2014-07-09T22:22:54+00:00

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).

perf symbols: Record the reason for filtering an address_location

2014-03-18T21:16:57+00:00

By turning the addr_location->filtered member from a boolean to a u8
bitmap, reusing (and extending) the hist_filter enum for that.

This patch doesn't change the logic at all, as it keeps the meaning of
al->filtered !0 to mean that the entry _was_ filtered, so no change in
how this value is interpreted needs to be done at this point.

This will be soon used in upcoming patches.

perf timechart: Fix off-by-one error in 'record' argv handling

2014-03-18T21:16:47+00:00

Since 367b315 (perf timechart: Add support for -P and -T in timechart
recording, 2013-11-01), the 'perf timechart record' command stopped
working:

  $ perf timechart record -- git status
  Workload failed: No such file or directory

This happens because of an off-by-one error while preparing the argv for
cmd_record(): it attempts to execute the command 'status' and complains
that it doesn't exist. Fix this error.

perf timechart: Fix wrong SVG height

2014-01-20T19:19:08+00:00

If we call perf timechart with -p 0 arguments, it means we don't want
any tasks related data. It works, but space for tasks data is reserved
in the generated SVG. Remove this unused empty space via passing 0 as
count to the open_svg.

perf tools: Introduce zfree

2013-12-27T18:17:00+00:00

For the frequent idiom of:

   free(ptr);
   ptr = NULL;

Make it expect a pointer to the pointer being freed, so that it becomes
clear at first sight that the variable being freed is being modified.
