Is anyone currently working on the next big step in the SMP
puzzle? That is, implementing kernel threads with preemptive
scheduling?
The idea being that one then has the ability to run
preemptable kernel threads in parallel on SMP-capable
boxes because the code must assume preemption in the
same manner on both uni and multi cpu systems.
Once implemented, we would begin to migrate functionality
from non-preemptive threads to preemptive threads from
the outside-in, and parallel SMP operation in supervisor
mode migrates along with it.
