[RFC 00/10] perf report: Add -F option for specifying output fields

[Namhyung Kim]

Hello,

This is a patchset implementing -F/--field option to setup output
field/column as Ingo requested.

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.


  $ perf report -s dso,sym
