Hi
I've got oprofile support for MIPS32 / MIPS64 style counters in the queue.
It still needs some debugging to become actually useful but anyway, I'm
going to check those patches into git in a few minutes.
Can these be used on the AMD AU1200 core?
(I don't see Register 25 on Coprocessor 0)
If OProfile cannot be used, what can I use to profile the kernel?
If there are no performance counters, OProfile can still use the system
timer to take samples each clock tick. This is the way I am using it.
To use it in this manner you have to hack up the code a bit so that the
return value of oprofile_arch_init() (in oprofile/common.c) is -ENODEV.
