Performance Monitoring Counters (PMC, PERFCTRS) and SMP?

Greg A. Woods — 2011-10-16T03:32:26

Is anyone by any chance working on SMP support for PMC / PERFCTRS?

Apparently FreeBSD is now able to support PMC on SMP machines, but I
can't find any hint of anything related for NetBSD.

I ask mostly because I'm flustered by getrusage(2) being as good as
useless for even the most basic of benchmarking purposes, and
gettimeofday() also being useless in a multi-user environment.

I guess a second question might be if anyone's thought of pulling over
FreeBSD's fix, or re-implementing something similar, to at least make
getrusage() monotonic?

(on a related note, does anyone know of any decent CPU measurement tool
for use inside a process on OS X?  getrusage() is broken there too.)

state of NetBSD SMP

So, what's the current state of NetBSD SMP, i.e. how many kernel  
subsystems do we still have to get out from under the big lock?

curious,
