virtio, vhost, pc, pci: documentation, fixes and cleanups Lots of fixes all over the place. Unfortunately, this does not yet fix a regression with vhost introduced by the last pull, the issue is typically this error: kvm_mem_ioeventfd_add: error adding ioeventfd: File exists followed by QEMU aborting.

Allow the PCIHostDeviceAddress structure to work as the host property in vfio-pci when it has it's default value of all fields set to ~0. In this form the property indicates a non-existant device but given the field bit sizes gets asserted as excess (and invalid) precision overflows the string buffer. The BDF of an invalid device "FFFF:FF:FF.F" is returned instead. Signed-off-by:

The legacy vring layout is not used anymore as we use the separate mappings even for legacy devices. This patch simply removes it. This also fixes a bug with virtio 1 devices when the vring descriptor table is mapped at a higher address than the used vring because the following function may return an insanely great value: hwaddr virtio_queue_get_ring_size(VirtIODevice *vdev, int n) { return vdev->vq[n].vring.used - vdev->vq[n].vring.desc + virtio_queue_get_used_size(vdev, n); } and the mapping fails. Signed-off-by: -
Greg Kurz authored
With virtio 1, the vring layout is split in 3 separate regions of contiguous memory for the descriptor table, the available ring and the used ring, as opposed with legacy virtio which uses a single region. In case of memory re-mapping, the code ensures it doesn't affect the vring mapping. This is done in vhost_verify_ring_mappings() which assumes the device is legacy. This patch changes vhost_verify_ring_mappings() to check the mappings of each part of the vring separately. This works for legacy mappings as well. Cc: qemu-stable@nongnu.org Signed-off-by:

Commit 31190ed7 added a migration blocker in vhost_dev_init() to check if memfd would succeed. It is better if this blocker first checks if vhost backend requires shared log. This will avoid a situation where a blocker is added inappropriately (e.g. shared log allocation fails when vhost backend doesn't support it). Signed-off-by:

virtio 1.0 spec says this is a legacy feature bit, hide it from guests in modern mode. Note: for cross-version migration compatibility, we keep the bit set in host_features. The result will be that a guest migrating cross-version will see host features change under it. As guests only seem to read it once, this should not be an issue. Meanwhile, will work to fix guests to ignore this bit in virtio1 mode, too. Cc: qemu-stable@nongnu.org Signed-off-by:
