Sure, it'll hit linux-next tomorrow, otherwise you can steal from http://ozlabs.org/~rusty/kernel/rr-latest (virtio:pci-minor-cleanups.patch and virtio:pci-minor-cleanups-fix.patch). > > But vector for something which isn't always the vector > > is misleading, IMHO. > > I think you mean it's isn't always used? It's always a vector ... The non-MSI case, it's set to VIRTIO_MSI_NO_VECTOR, and we use a normal interrupt vector. > BTW, let's get rid of msix_enabled completely? > We can always use msix_vectors ... That would be nice. But yes, requiring more audit. Ideally, if msix_vectors == 0, implies intx_enabled.
