I dunno if you're aware of this but I've been working on a perf
backend for OProfile. Currently only ARM and SH are making use of it,

It would be trivial to add MIPS support but I suspect that would
require you to rework this patch series. However, what we should try
to avoid is duplicating any effort of getting perf and OProfile
working together.

Would you mind waiting for my patch series to be merged before
starting work on your perf-OProfile patchset for MIPS? Alternatively,
you can base your work on,

git:// perf-oprofile
