2016-06-15T13:50:04+00:00

perf hists: Replace perf_evsel arg perf_hpp_fmt's header callback

2016-06-15T13:49:18+00:00

Replacing perf_evsel arg perf_hpp_fmt's header callback with hists
object.

None of the actual callbacks actually use evsel object, also this will
be helpful in future for non evsel related hist browsers.

perf report: Use hierarchy hpp list on stdio

2016-03-08T09:11:20+00:00

Now hpp formats are linked using perf_hpp_list_node when hierarchy is
enabled.  Use this info to print entries with multiple sort keys in a
single hierarchy properly.

For example, the below example shows using 4 sort keys with 2 levels.

  $ perf report --hierarchy -s '{prev_pid,prev_comm},{next_pid,next_comm}' \
   --percent-limit 1 -i perf.data.sched
  ...
  #    Overhead  prev_pid+prev_comm / next_pid+next_comm

perf hists: Fix indent for multiple hierarchy sort key

2016-03-08T09:11:20+00:00

When multiple sort keys are used in a single hierarchy, it should indent
using number of hierarchy levels instead of number of sort keys.
