[PATCHSET 00/17] perf report: Add -F option for specifying output fields (v4)
From: Namhyung Kim
Date: Tue Apr 15 2014 - 23:12:39 EST
Hello,
This is a patchset implementing -F/--fields option to setup output
field/column as Ingo requested. It depends on my --percentage
patchset [1].
The -F option can receive any sort keys that -s option recognize, plus
following fields (name can be changed):
overhead, overhead_sys, overhead_us, sample, period
The overhead_guest_sys and overhead_guest_us might be avaiable when
you profile guest machines.
Output will be sorted by in order of fields and sort keys passed by -s
option will be added to the output field list automatically. If you
want to change the order of sorting you can give -s option in addition
to -F option. To support old behavior, it'll also prepend 'overhead'
field to the sort keys unless you give -F option explicitly.

* changes in v4:
- fix a tui navigation bug
- fix a bug in output change of perf diff
- move call to perf_hpp__init() out of setup_browser()
- fix alignment of some output fields on stdio
* changes in v3:
- rename to --fields option for consistency (David)
- prevent to add same keys multiple times
- change dso sorting to show unknown dsos last
- fix minor bugs
* changes in v2:
- add a cleanup patch using ui__has_annotation()
- cleanup default sort order managment
- support perf top also
- handle elided sort entries properly
- add Acked-by's from Ingo
