Ah, okay.

How about this:


-c::
--comms=::
Only consider symbols in these comms. CSV that understands
file://filename entries. This option will affect the percentage of
overhead column. See --percentage for more info.
-d::
--dsos=::
Only consider symbols in these dsos. CSV that understands
file://filename entries. This option will affect the percentage of
overhead column. See --percentage for more info.
-S::
--symbols=::
Only consider these symbols. CSV that understands
file://filename entries. This option will affect the percentage of
overhead column. See --percentage for more info.

--percentage::
Determine how to display the overhead percentage of filtered entries.
Filters can be applied by --comms, --dsos and/or --symbols options and
Zoom operations on the TUI (thread, dso, etc).

"relative" means it's relative to filtered entries only so that the
sum of shown entries will be always 100%. "absolute" means it retains
original value before and after the filter applied.


Thanks,
Namhyung
