2008-01-30KVM: Move apic timer migration away from critical sectionAvi Kivity
Migrating the apic timer in the critical section is not very nice, and is absolutely horrible with the real-time port. Move migration to the regular vcpu execution path, triggered by a new bitflag. Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-01-30KVM: Accelerated apic supportAvi Kivity
This adds a mechanism for exposing the virtual apic tpr to the guest, and a protocol for letting the guest update the tpr without causing a vmexit if conditions allow (e.g. there is no interrupt pending with a higher priority than the new tpr). Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-01-30KVM: local APIC TPR access reporting facilityAvi Kivity
Add a facility to report on accesses to the local apic tpr even if the local apic is emulated in the kernel. This is basically a hack that allows userspace to patch Windows which tends to bang on the tpr a lot. Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-01-30KVM: Move arch dependent files to new directory arch/x86/kvm/Avi Kivity
This paves the way for multiple architecture support. Note that while ioapic.c could potentially be shared with ia64, it is also moved. Signed-off-by: Avi Kivity <avi@qumranet.com>
