Re: Removal of events for unsupported architectures or processor models

Maynard,

IBS actually supports in perf subsystem. Let me look in to the current 
code and get back to you if we can extend this to operf.  However, I 
should be able to provide patch to remove IBS from from the opcontrol.

Let me know what you think?

Thank you,

Suravee

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:
