briggs	0b956d0b8b	Implement pmc(9) -- An interface to hardware performance monitoring ... counters. These counters do not exist on all CPUs, but where they do exist, can be used for counting events such as dcache misses that would otherwise be difficult or impossible to instrument by code inspection or hardware simulation. pmc(9) is meant to be a general interface. Initially, the Intel XScale counters are the only ones supported.	2002-08-07 05:14:47 +00:00
