Subject: [RFC 5/5] perf: Enable multiple hist_entry_group output
Enable multiple hist_entry_group groups in the output based on a sort
method.
Currently only 'perf report' is hooked in with '--group-sort='. The choices
are cpu, pid, and cacheline. Only --stdio works right now. I haven't figured
out how the other outputs work.
Sample output from 'perf mem record -a grep -r foo /* > /dev/null'
(normal) perf mem report --percent-limit=1.0 --stdio
