In virtqueue_{split,packed}_get_avail_bytes() descriptors are read
in a loop via MemoryRegionCache regions and calls to
vring_{split,packed}_desc_read() - these take a region cache and the
index of the descriptor to be read.
For direct descriptors we use a cache provided by the caller, whose
size
When a virtqueue size is changed by the guest via
virtio_queue_set_num(), its region cache is not automatically updated.
If the size was increased, this could lead to accessing the cache out
of bounds. For example, in vring_get_used_event():

(This RFC patch series is based on AMD's RFC upmv10-snpv3 tree [1]. So
far that RFC tree was not submitted for review in qemu-devel.)
In order to enable measured direct kernel boot on SNP, QEMU needs to
fill the hashes page when kernel-hashes=on. This relies on several
changes to the SNP

This means handling the new exit reason for Xen but still
crashing on purpose. As we implement each of the hypercalls
we will then return the right return code.

The xen_overlay device (and later similar devices for event channels and
grant tables) need to be instantiated. Do this from a kvm_type method on
the PC machine derivatives, since KVM is only way to support Xen emulation
for now.

Hi,
I found the issue by chance, while working in not-yet-upstreamed virtio
code. I am not sure if there is any QEMU stub currently
upstreamed that does not support an F_CONFIG backend, to be able to trigger
the error. It may as well be that this branch
of the condition is never executed.

Hi,
Meson "wrap" is a mechanism to build dependencies that doesn't rely on git
submodules and integrate external dependencies as subproject()s.
This offers developpers a simpler way to build QEMU with missing system
dependencies (ex, libslirp in my case), but also

The following patches are going to introduce meson wrap dependencies,
