The other thing is that this assumes, that all time sources are
programmable per cpu, otherwise it will be more complicated for a time
source to run the timers for every cpu, I don't know how safe that
assumption is. Changing the array of structures into an array of
pointers to the structures would allow to switch between percpu bases
and a single base.
yeah, and that's an assumption that simplifies things on SMP
significantly. PIT on SMP systems for HRT is so gross that it's not
funny. If anyone wants to revive that notion, please do a separate patch
and make the case convincing enough ...
Lets not talk about PIT, but, a lot of SMP platforms do NOT have per cpu timers. For those, it
would seem having per cpu lists to handle the timer is not really reasonable.
