The following arguments are in favor: - allow in-kernel paravirt drivers to interrupt the guest without going through qemu (which involves a signal and some complexity) - same for guest SMP IPI - reduced overhead for a much-loved hardware component (especially on Windows, where one regularly sees 100K apic updates a second) The strength of these arguments increase as vmexit overhead decreases with improving hardware. Of course, pushing such a piece of misery into the kernel where it can cause much pain should not be done lightly. -- error compiling committee.c: too many arguments to function ------------------------------------------------------------------------- Take Surveys.
