Sebastien Boeuf 5e803ab18f vmm: Integrate userspace IOAPIC ... The previous commit introduced a userspace implementation of an IOAPIC and this commits aims to plumb it into the cloud-hypervisor VMM. Here is the list of new things brought by this patch: - Update the rust-vmm/kvm-ioctls dependency to benefit from latest patches including the support for split irqchip, and the vector being returned when a VM exit is caused by an EOI. - Enable the split irqchip (which means no IOAPIC or PIC is emulated in kernel). This is done conditionally based on the support of the TSC_DEADLINE_TIMER from both KVM and the underlying CPU. The dependency on TSC_DEADLINE_TIMER is related to KVM which does not support creating the in kernel PIT if it has a split irqchip. - Rely on callbacks to handle the following use cases: - in kernel IOAPIC + serial IRQ (pin based) - in kernel IOAPIC + virtio-pci MSI-X - in kernel IOAPIC + virtio-pci IRQ (pin based) - userspace IOAPIC + serial IRQ (pin based) - userspace IOAPIC + virtio-pci MSI-X - userspace IOAPIC + virtio-pci IRQ (pin based) Fixes #13 Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>		2019-06-21 10:09:34 +02:00
