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


From: 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
