[Qemu-devel] [PATCH v2 0/2] virtio-serial: virtio console emergency write support

[Sascha Silbe]

This series adds support for the virtio 1.0 "emergency write"
(VIRTIO_CONSOLE_F_EMERG_WRITE) virtio feature. This is useful for
early guest debugging and might be used in cases where the guest
crashes so badly that it cannot use virtqueues.

v1→v2:
  - rebased on current master (resolved conflict: virtio-pci
    page-per-vq compat property)
  - split into two patches; no code changes (requested by Amit)

Sascha Silbe (2):
  virtio-serial: add plumbing for virtio console emergency write support
  virtio-serial: enable virtio console emergency write feature
