Re: MONITOR and MWAIT Instruction Emulation in BOCHS

one other thing is that in modern OS and applications Monitor & Mwait are
used to reduce power on the processors. on a overcommited system ( i.e.
emulating 16 cores on a machine with only 4 cores). this sequence should be
able to use as a hint to schedule the virtual core intelligently. can
anyone familiar with this comment on this ?
