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

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.

A basic port to the Broadcom/SiByte SB1250 evaluation board (the

"swarm").  Other SB-cpu boards will be supported by this port in
the future.

Includes support for on-chip ethernet and serial.  Many features
still missing - notably SMP, PCI/LDT and IDE.
