Only the operf profiler -- which uses the Linux Kernel Performance Events Subsystem (aka "perf_events") -- will be included in release 1.0. It seems logical at this time to also remove the events and unit mask files for any architecture or processor types that are not supported by perf_events. From what I can tell, here are the architectures that do not have perf_events support: > > avr32 > ia64 > > Unsupported processor models are: > > ppc64/cell-be > ppc64/pa6t (?) PA6T never got enabled for perf (it was a brand new thing around the time when we were actively working on it). I'm not going to hold up progress just for this platform, since the number of users is very small. I can make do with old versions of oprofile going forward, and/or do the work and enable it for perf properly if I ever need to, which I doubt. :) -Olof ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
