Steve Rutherford b053b2aef2 KVM: x86: Add EOI exit bitmap inference ... In order to support a userspace IOAPIC interacting with an in kernel APIC, the EOI exit bitmaps need to be configurable. If the IOAPIC is in userspace (i.e. the irqchip has been split), the EOI exit bitmaps will be set whenever the GSI Routes are configured. In particular, for the low MSI routes are reservable for userspace IOAPICs. For these MSI routes, the EOI Exit bit corresponding to the destination vector of the route will be set for the destination VCPU. The intention is for the userspace IOAPICs to use the reservable MSI routes to inject interrupts into the guest. This is a slight abuse of the notion of an MSI Route, given that MSIs classically bypass the IOAPIC. It might be worthwhile to add an additional route type to improve clarity. Compile tested for Intel x86. Signed-off-by: Steve Rutherford <srutherford@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>		2015-10-01 15:06:28 +02:00
