I'm trying to setup a custom SMP MIPS platform to use oprofile for linux 2.6.x.
To start with I would like to user the timer interrupt mode. Does this mode support SMP config? In other words, do I get SMP call histogram using the timer interrupt mode?
I've downloaded the latest oprofile driver (kernel.org
) and the oprofile utilities (oprofile sourceforge website).
Assuming I have an SMP linux running on the platform, is there anything else I need to do to get oprofile to work? I'm not interested in setting up the performance counter interrupt based profiling yet. I just want kernel function call histogram to start with.
