[PATCH RFC 00/11] linux: towards virtio-1 guest support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Thomas Huth (1):
  KVM: s390: Set virtio-ccw transport revision
