Subject: [Qemu-devel] [PATCH 0/3] virtio-pci: 1.0 tweaks
Date: Thu, 22 Jan 2015 09:57:32 +0100	[thread overview]
Message-ID: <1421917056-6560-1-git-send-email-kraxel@redhat.com> (raw)

  Hi,

Continued to look at virtio-1.0.  Added flags to turn off legacy/modern
mode for virtio devices.

Figured notification seems to not be adapted to virtio 1.0 yet:  Apply
this patchset, boot with -device virtio-net-pci,disable-legacy=on, watch
qemu blow up in virtio_pci_set_host_notifier_internal, because it uses
uninitialited proxy->bar without checking.  Looked closer, seems the
virtio 1.0 notification memory region isn't wired up yet ...

Gerd Hoffmann (3):
  virtio-pci: add flags to enable/disable legacy/modern
  virtio-pci: use bar0 for non-transitional devices
  virtio-pci: make QEMU_VIRTIO_PCI_QUEUE_MEM_MULT smaller
