KVM: in-kernel LAPIC save and restore support 2007-10-13T08:18:25+00:00 Eddie Dong eddie.dong@intel.com 2007-09-06T09:22:56+00:00 96ad2cc6132479aa0aea485d0838a13fda765bd5 This patch adds a new vcpu-based IOCTL to save and restore the local apic registers for a single vcpu. The kernel only copies the apic page as a whole, extraction of registers is left to userspace side. On restore, the APIC timer is restarted from the initial count, this introduces a little delay, but works fine.

The local APIC is one such device, especially for Windows and for SMP, so we add an APIC model to kvm. It also allows in-kernel host-side drivers to inject interrupts without going through userspace.
