[Qemu-devel] [PATCH 0/6] vhost: cross-endian support

[Greg Kurz]

Hi,

This series brings initial enablement in vhost to support legacy virtio
devices when host and guest have different endianness (for example, ppc64
versus ppc64le).

Only vhost_net is fully enabled at the moment... I haven't looked at
vhost_scsi yet.

It is basically the same patch set I had sent last month:

https://lists.gnu.org/archive/html/qemu-devel/2015-05/msg00780.html

... without the "virtio: relax feature check" patch since QEMU now
supports 64-bit features.

Some kernel support is needed, already available in Michael's vhost-next
branch at:

https://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git

Please review.
