I'm trying to learn a bit more about clocks and ticks on NetBSD as part
of my effort to try to improve measurement of CPU usage, etc.
What follows is a set of changes I've made to kern_clock.c from
netbsd-5. These are mostly new or moved comments to try to better
explain things to myself
The
Title says it all.
Here's a proposal for a sysctl(7) knob to easily allow non-superusers to
set the CPU affinity of processes and threads they own:
security.secmodel.suser.usersetaffinity
(ressembles the one already existing to allow for user mounts)
Would it be acceptable to modify current
