1. Can somebody suggest what would be a good counter value reset if I want
to use Oprofile for call-graph profiling? I would like to be as accurate as
possible in obtaining the call-graphs. Is there a suggested call-depth
2. Also, just wanted to confirm if I was doing it right - I have compiled
the kernel with frame pointers and I hope that is sufficient to generate
call-graphs from oprofile? Apart from this, I need to specific call-depth
to opcontrol and then after running whatever I need to, I just do a opreport
3. Another question I have is regarding opreport, when I use "separate=all"
option with opcontrol. When I try opreport it just does not allow me unless
I say "merge=tgid". I understand why I should do this, but what I do not
understand is that opreport fails saying it parsed some files twice, when I
do a "merge=cpuid" option. Does anybody know why?
Thanks in advance.
