[Qemu-devel] [PATCH RFC 0/7] vhost: cross-endian support (vhost-net only)

[Greg Kurz]

Hi,

This series allows QEMU to use vhost with legacy virtio devices when
host and target don't have the same endianness. Only network devices
are covered for the moment.

I had already posted a series some monthes ago but it never got reviewed.
Moreover, the underlying kernel support was entirely re-written and is still
waiting to be applied by Michael. I hence post as RFC.

The corresponding kernel patches are available here:

Please comment.

      vhost_net: re-enable when cross endian

Greg Kurz (6):
      virtio: relax feature check
      linux-headers: sync vhost.h
      virtio: introduce virtio_legacy_is_cross_endian()
      vhost: set vring endianness for legacy virtio
      tap: add VNET_LE/VNET_BE operations
      vhost-net: tell tap backend about the vnet endianness
