Hi all,
I've been struggling with a bug which seems to be linked to several issues
in the polling system on Windows hosts.
When connecting gdb to a qemu-system (it happens with all the emulations
I've tried), I've discovered that sometimes a latency appears. It happens
with all the commands but

Since MSI-x masking handlers are only implemented for IO queues, if we
want to use qtest we need to implement utilities for controller

Currently armv7m_load_kernel() takes the size of the block of memory

Hi!
So
Next patch will skip the registering of dma maps that the vdpa device
rejects in the iova tree. We need to consider that here or we cause a
SIGSEGV accessing result.

Since QEMU will be able to inject new elements on CVQ to restore the
state, we need not to depend on a VirtQueueElement to know if a new
element has been used by the device or not. Instead of check that, check
if there are new elements only using used idx on vhost_svq_flush.

Nothing actually reads the return value, but an error in cleaning some
entries could cause device stop to abort, making a restart impossible.
Better ignore explicitely the return value.

Collection of iova tree fixes detected preparing live migration with real
devices and multiqueue.
These cannot be triggered in simple setups (vdpa_sim_net, no display, no
device reset with different features) but it's possible to trigger them with
real devices or if the kernel fails some step
If a map fails for whatever reason, it must not be saved in the tree.
Otherwise, qemu will try to unmap it in cleanup, leaving to more errors.

If you specify a known backend but it isn't compiled in, or failed to
initialize, you get a simple warning and the "none" backend as a
fallback, and QEMU runs happily:
$ qemu-system-x86_64 -audiodev id=audio,driver=dsound
audio: Unknown audio driver `dsound'

It's convenient to call iova_tree_remove from a map returned from
iova_tree_find or iova_tree_find_iova. With the current code this is not
possible, since we will free it, and then we will try to search for it
again.
Fix it making accepting the map by value, forcing a copy of the
argument. Not
Since we're going to allow SVQ to add elements without the guest's
knowledge and without its own VirtQueueElement, it's easier to check if
an element is a valid head checking a different thing than the
VirtQueueElement.
