Thanks, is it possible to use MSI-X as well? The virtio spec
indicates to use legacy irq or
MSI-X only.
I supposed yes. It is depend MSI controller type in EP side.
But not like standard PCI MSI-X, it is platform MSI-X irq.
If use GIC-its, it should support MSI-X.
Thomas Gleixner is working on pre-device msi irq domain.
