[Qemu-devel] [PATCH v3 00/25] virtio: add version 1.0 support, move to 32bit

[Gerd Hoffmann <kraxel@redhat.com>]

  Hi,

This patch series adds virtio 1.0 support to the virtio blk and scsi
drivers in seabios.  With this series applied seabios happily boots
in virtio 1.0 mode from both transitional and modern devices.  This
series also moves all virtio code to 32bit.

Tested with Fedora 22 guest, booting from virtio-scsi cdrom (live iso),
virtio-scsi disk and virtio-blk disk.

The patches are also available in the git repository at:
  git://git.kraxel.org/seabios virtio

v3 changes:
  * change vp_device allocation.
  * fix capability detection.
  * add some cleanup patches (drop MAKESEGMENT and GET_* macros).
  * allocate virt queues in high memory.

v2 changes:
  * rename vp_modern_{read_write} to vp_{read,write}
  * switch legacy virtio code to vp_{read,write} too.
  * make vp_read return the values.
