This patchset tries to go towards implementing both virtio-1 compliant and transitional virtio drivers in Linux. Branch available at git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux virtio-1 This is based on some old patches by Rusty to handle extended feature bits and endianness conversions. Thomas implemented the new virtio-ccw transport revision command, and I hacked up some further endianness stuff and virtio-ccw enablement. Probably a lot still missing, but I can run a virtio-ccw guest that enables virtio-1 accesses if the host supports it (via the qemu host patchset) - virtio-net and virtio-blk only so far. I consider this patchset a starting point for further discussions. Cornelia Huck (5): virtio: endianess conversion helpers virtio: allow transports to get avail/used addresses virtio_blk: use virtio v1.0 endian KVM: s390: virtio-ccw revision 1 SET_VQ KVM: s390: enable virtio-ccw revision 1 Rusty Russell (5): virtio: use u32, not bitmap for struct virtio_device's features virtio: add support for 64 bit features. virtio_ring: implement endian reversal based on VERSION_1 feature. virtio_config: endian conversion for v1.0. virtio_net: use v1.0 endian.
