[Qemu-devel] monitor/mwait support for X86_64

Hi all,

    We want to use QEMU to test some OS features on x86_64 systems. This
feature requires the monitor and mwait instructions on x86, but we do not
know whether QEMU currently support this. I got a QEMU copy from
http://git.qemu.org/qemu.git, and grep "monitor" in the source code tree,
only found results are in the directory target-i386. Does that mean all
supports are limited on i386 systems? Any feedbacks are welcome!


Thanks, Yan

target-i386 implements emulation of both 32- and 64-bit x86 systems.  So 
it covers both i386 and x86_64.

Thanks,
