Is this thread-safe? I think
On macOS, private $TMPDIR's are the default. These $TMPDIR's are
generated from a user's unix UID and UUID [1], which can create a
relatively long path:
/var/folders/d7/rz20f6hd709c1ty8f6_6y_z4gn/T/
QEMU's avocado tests create a temporary directory prefixed by
"avo_qemu_sock_", and create
v2:
- Reduced QEMUMachine socket directory prefix length.
- Replaced QEMUMachine default name with "qmp".
- Rewrote commit description.
Thanks,
Peter Delevoryas

It allows to run commands at start of the device, before it have enabled

It was easier to allow vhost_svq_add to handle the memory. Now that we
will move SVQDesc to an opaque context, it's better to handle it in the
caller.

Since we'll allow net/vhost-vdpa to add elements that don't come from

To restore the device in the destination of a live migration we send the
commands through control virtqueue. For a device to read CVQ it must
have received DRIVER_OK status bit.
However this open a window where the device could start receiving
packets in rx queue 0 before it receive the RSS config
CVQ of net vhost-vdpa devices can be intercepted since the work of [1]. The
virtio-net device model is updated. The migration was blocked because although
the state can be megrated between VMM it was not possible to restore on the
destination NIC.
This series add support for SVQ to inject external
So we can reuse to inject state messages.

The SVQ vring used idx usually match with the guest visible one, as long
as all the guest buffers (GPA) maps to exactly one buffer within qemu's
VA. However, as we can see in virtqueue_map_desc, a single guest buffer
could map to many buffers in SVQ vring.
The solution is to stop using the device'
Migration with SVQ already migrate the inflight descriptors, so the
destination can perform the work.
This makes easier to migrate between backends or to recover them in
vhost devices that support set in flight descriptors.

There is nothing in the specs on DMA engine interrupt lines: it should have
been in the "BCM2835 ARM Peripherals" datasheet but the appropriate
"ARM peripherals interrupt table" (p.113) is nearly empty.
