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
