Subject: [RFC] Fix rocker device null pointer crash. qemu config r->fp_ports
with "-device rocker,len-ports=10" when guest config port larget then
r->fp_ports(10)
On AMD machines with SEV/SMD the physical address space needs
to be reduced by a number of bits. Linux does this correctly
and shows this information in /proc/cpuinfo. CPUID set by qemu
however reports too big physical addresses i.e. 48 bit instead of 43.
This patch has been tested on both Intel
From: Stefano Garzarella
The `aio-max-batch` parameter will be propagated to AIO engines
and it will be used to control the maximum number of queued requests.
When there are in queue a number of requests equal to `aio-max-batch`,
the engine invokes the system call to forward the requests to the

When there are multiple queues attached to the same AIO context,
some requests may experience high latency, since in the worst case
the AIO engine queue is only flushed when it is full (MAX_EVENTS) or
there are no more queues plugged.

From: Stefano Garzarella
Changes in preparation for next patches where we add a new
parameter not related to the poll mechanism.
Let's add two new generic functions (iothread_set_param and
iothread_get_param) that we use to set and get IOThread
parameters.

Hi all,
At Collabora we have started looking at Vulkan support in QEMU with Virgil.
We have seen the work that Vivek has submitted to support the new
virtio-gpu BLOB API (thanks!) and have identified a few holes that are
still needed for Vulkan support.
We would like to know if anybody else

Better reflect the command line version of the socket address arguments,
following the now recommended long-form opt=on syntax.
