The patch looks fine for 2.4 purposes, but for 2.5/2.6, I'd much prefer to see all PMU-related manipulation done in user-space (through the perfmon syscall and/or pfmlib). I really don't want to have to maintain _two_ subsystems that need to be updated with each new processor. I talked to Stephane about this and he said he should have the "custom sampling buffer format" patch ready in about a week's time. Once that is in, you should be able to hook oprofile to perfmon with a trivial glue "module". --david
