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
