maybe you can drive the jtag directly.

It's unfortunate that the times in the protocol have low resolution.
I think ix does better.
Latency is worse than using mwait because you are sleeping unconditionally.
Mwait does not prevent you from getting the interrupt to schedule.
By this I mean that mwait unblocks on interrupt. You could do something
like

for those without much mwait experience, mwait is a kernel-only primitive
(as per the instructions) that pauses the processor until a change has been
made in some range of memory. the size is determined by probing the h/w,
but think cacheline. so the discussion of locking is kernel specific as
The original discussion started about the runq spin lock, but I
think the scope of the problem is more general and the solution can be
applied in user and kernel space both. While in user space you would
do sleep(0) in the kernel you would sched() or if you are in the
scheduler you would
