The initialization sequence follows the ixy.rs user space driver and the X550 datasheet. The driver operates a single receive and transmit queue. It prefers MSI-X over the legacy interrupt, because a hypervisor is not obliged to offer one for a passed-through device and QEMU in fact does not, which leaves MSI-X as the only way to receive interrupts at all. Should neither be available, the device still makes progress when the kernel is built with the idle-poll feature. This makes the msix module available outside of virtio.

I have rebased, resolved conflicts, and squashed. I will do a proper review in the coming days. :) |
