2023-10-04virtio: add vhost-user-base and a generic vhost-user-deviceAlex Bennée
In theory we shouldn't need to repeat so much boilerplate to support vhost-user backends. This provides a generic vhost-user-base QOM object and a derived vhost-user-device for which the user needs to provide the few bits of information that aren't currently provided by the vhost-user protocol. This should provide a baseline implementation from which the other vhost-user stub can specialise.

2023-10-04hw/virtio/meson: Rename softmmu_virtio_ss[] -> system_virtio_ss[]Philippe Mathieu-Daudé
Similarly to commit de6cd7599b ("meson: Replace softmmu_ss -> system_ss"), rename the virtio source set common to all system emulation as 'system_virtio_ss[]'. This is clearer because softmmu can be used for user emulation.

2022-10-09qmp: add QMP command x-query-virtioLaurent Vivier
This new command lists all the instances of VirtIODevices with their canonical QOM path and name. [Jonah: @virtio_list duplicates information that already exists in the QOM composition tree. However, extracting necessary information from this tree seems to be a bit convoluted. Instead, we still create our own list of realized virtio devices but use @qmp_qom_get with the device's canonical QOM path to confirm that the device exists and is realized. If the device exists but is actually not realized, then we remove it from our list (for synchronicity to the QOM composition tree). Also, the QMP command @x-query-virtio is redundant as @qom-list and @qom-get are sufficient to search '/machine/' for realized virtio devices. However, @x-query-virtio is much more convenient in listing realized virtio devices.] Signed-off-by: Laurent Vivier <lvivier@redhat.com> Signed-off-by: Jonah Palmer <jonah.palmer@oracle.com> Message-Id: <1660220684-24909-2-git-send-email-jonah.palmer@oracle.com> Reviewed-by: Michael S.

2022-03-15vhost: Add VhostIOVATreeEugenio Pérez
This tree is able to look for a translated address from an IOVA address. At first glance it is similar to util/iova-tree. However, SVQ working on devices with limited IOVA space need more capabilities, like allocating IOVA chunks or performing reverse translations (qemu addresses to iova). The allocation capability, as "assign a free IOVA address to this chunk of memory in qemu's address space" allows shadow virtqueue to create a new address space that is not restricted by guest's addressable one, so we can allocate shadow vqs vrings outside of it. It duplicates the tree so it can search efficiently in both directions, and it will signal overlap if iova or the translated address is present in any tree.

2022-03-15vhost: Add VhostShadowVirtqueueEugenio Pérez
Vhost shadow virtqueue (SVQ) is an intermediate jump for virtqueue notifications and buffers, allowing qemu to track them. While qemu is forwarding the buffers and virtqueue changes, it is able to commit the memory it's being dirtied, the same way regular qemu's VirtIO devices do. This commit only exposes basic SVQ allocation and free. Next patches of the series add functionality like notifications and buffers forwarding.
