[PATCHv2] virtio: Introduce vringh wrappers in virtio_config
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
Add wrappers for the host vrings to support loose
coupling between the virtio device and driver.
A new struct vringh_config_ops with the functions
find_vrhs() and del_vrhs() is added to the virtio_device
struct. This enables virtio drivers to manage virtio
host rings without detailed knowledge of how the
vrings are created and

[PATCH v3 6/7] virtio: add explicit big-endian support to memory accessors
The current memory accessors logic is:
- little endian if little_endian
- native endian (i.e. no byteswap) if !little_endian
If we want to fully support cross-endian vhost, we also need to be
able to convert to big endian.
Instead of changing the little_endian argument to some 3-value enum, this
patch changes the logic to:
- little endian if little_endian
- big endian if !little_endian

[PATCH v3 0/7] vhost: support for cross endian guests
Hi,
This patchset allows vhost to be used with legacy virtio when guest and host
have a different endianness.
Patches 1-6 remain the same as the previous post. Patch 7 was heavily changed
according to MST's comments.

[PATCH v5 0/8] vhost: support for cross endian guests
Hi,
This patchset allows vhost to be used with legacy virtio when guest and host
have a different endianness. It is compatible with modern virtio and can be
fully compiled out through kernel config.
FWIW, I could flawlessly kexec/reboot guests from ppc64 to ppc64le and back.
I could also migrate from a ppc64 to a ppc64le host and back. No regressions
on x86 as expected. My experimental QEMU tree

Patches 1 to 5 are preliminary work: we move the endianness check out of all
