[PATCH RFC v6 00/20] qemu: towards virtio-1 host support
And yet another iteration of virtio-1 support in qemu, tested with the
latest virtio kernel patches. Find it at
git://github.com/cohuck/qemu virtio-1
Changes from v5:
- fixed stupid bug in "virtio: support more feature bits": we need to
define a proper prop backend for 64 bit wide handling...
- don't negotiate revision 1 unless VERSION_1 is offered
- use 64 bit wide features

[PATCH RFC v4 00/16] qemu: towards virtio-1 host support
Yet another version of the virtio-1 support patches.
This one has seen some (very) light testing with the virtio-1 guest
support patches currently on vhost-next.
Changes from v3:
- Add support for FEATURES_OK. We refuse to set features after the
driver has set this in the status field, and we allow to fail
setting the status if the features are inconsistent.
- Add missing virtio-1 changes

[PATCH RFC v5 00/19] qemu: towards virtio-1 host support
Another iteration of virtio-1 patches for qemu, as always available on
git://github.com/cohuck/qemu virtio-1
This one seems to work together with the current vhost-next patches
(well, I can ping :)
Changes from v4:
- add helpers for feature bit manipulation and checking
- use 64 bit feature bits instead of 32 bit arrays
- infrastructure to allow devices to offer different sets of feature
bits
