[src/trunk]: src/sys Implement pmc(9) -- An interface to hardware performance...
details: https://anonhg.NetBSD.org/src/rev/6c6dedf38ac9
branches: trunk
changeset: 534954:6c6dedf38ac9

description:
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.
