FYI - In an attempt to not make this an RTFM answer, I checked the FAQ and
read all online docs. The question remains.....
What is the status of profiling support for loaded kernel modules?
Call backtrace profiling looked promising in that it uses /proc/ksyms. Sadly
I was unable to inform gprof about loaded module symbols? What am I missing
here?
Intel Project: Linux InfiniBand I/O stack development.
Given the layered IB code is developed by three different groups and
specifically designed as loaded modules, static linking the code into the
kernel is an undesirable time sink at this juncture. Therefore profiling
kernel modules is about the only way to move from beta code to full
performance.
Thank you,
