Hi, This patchset allows vhost_net to be used with legacy virtio when guest and host have a different endianness. It is based on previous work by Cédric Le Goater: https://www.mail-archive.com/kvm-ppc@xxxxxxxxxxxxxxx/msg09848.html As suggested by MST: - the API now asks for a specific format (big endian) instead of the hint whether byteswap is needed or not (patch 1) - rebased on top of the virtio-1 accessors (patch 2) Patch 3 is a separate fix: I think it is also valid for virtio-1. Please comment. --- Greg Kurz (3): vhost: add VHOST_VRING_F_LEGACY_BIG_ENDIAN flag vhost: add support for legacy virtio vhost_net: fix virtio_net header endianness drivers/vhost/net.c | 32 ++++++++++++++++++++++++++------ drivers/vhost/vhost.c | 6 +++++- drivers/vhost/vhost.h | 23 +++++++++++++++++------ include/uapi/linux/vhost.h | 2 ++ 4 files changed, 50 insertions(+), 13 deletions(-) -- Greg _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
