This tests the commit 196ea60a73 ("hw/smbios: Fix core count in
type4").
In smbios_build_type_4_table() (hw/smbios/smbios.c), if the number of
cores in the socket is not more than 255, then smbios type4 table
encodes cores per socket into the core count field.
So for the topology in this case, there're the following considerations:
1. cores per socket should be not more than 255 to ensure we could cover
the core count field.
2. The original bug was that cores per socket was miscalculated, so now
we should include as many topology levels as possible (mutiple
sockets & dies, no module since x86 hasn't supported it) to cover
more general topology scenarios, to ensure that the cores per socket
encoded in the core count field is correct.
Based on these considerations, select the topology with multiple sockets
and dies:
-smp 54,sockets=2,dies=3,cores=3,threads=3
The expected core count = cores per socket = cores (3) * dies (3) = 9.

This tests the commit d79a284a44 ("hw/smbios: Fix smbios_smp_sockets
calculation").
In smbios_get_tables() (hw/smbios/smbios.c), smbios type4 table is built
for each socket, so the count of type4 tables should be equal to the
number of sockets.
Thus for the topology in this case, there're the following considerations:
1. The topology should include multiple sockets to ensure smbios could
create type4 tables for each socket.
2. In addition to sockets, for the more general topology, we should also
configure as many topology levels as possible (multiple dies, no
module since x86 hasn't supported it), to ensure that smbios is able
to exclude the effect of other topology levels to create the type4
tables only for sockets.
3. The original miscalculation bug also misused "smp.cpus", so it's
necessary to configure "cpus" (presented threads for machine) and
"maxcpus" (total threads for machine) as well to make sure that
configuring unpluged CPUs in smp (cpus < maxcpus) does not affect
the correctness of the count of type4 tables.
Based on these considerations, select the topology as the follow:
-smp cpus=100,maxcpus=120,sockets=5,dies=2,cores=4,threads=3
The expected count of type4 tables = sockets (5).

At present, to enable the VIRTIO_NET_F_RSS feature, eBPF must
be loaded for the vhost backend.
Given that vhost-vdpa is one of the vhost backend, we need to
implement the SetSteeringEBPF method to support RSS for vhost-vdpa,
even if vhost-vdpa calculates the rss hash in the hardware device
instead of in the kernel by eBPF.
Although this requires QEMU to be compiled with `--enable-bpf`
configuration even if the vdpa device does not use eBPF to
calculate the rss hash, this can avoid adding the specific
conditional statements for vDPA case to enable the VIRTIO_NET_F_RSS
feature, which reduces code maintainbility.

Handle output IO messages in the transmit (TX) virtqueue.
It allocates a VirtIOSoundPCMBuffer for each IO message and copies the
data buffer to it. When the IO buffer is written to the host's sound
card, the guest will be notified that it has been consumed.
The lifetime of an IO message is:
1. Guest sends IO message to TX virtqueue.
2. QEMU adds it to the appropriate stream's IO buffer queue.
3. Sometime later, the host audio backend calls the output callback,
virtio_snd_pcm_out_cb(), which is defined with an AUD_open_out()
call. The callback gets an available number of bytes the backend can
receive. Then it writes data from the IO buffer queue to the backend.
If at any time a buffer is exhausted, it is returned to the guest as
completed.
4. If the guest releases the stream, its buffer queue is flushed by
attempting to write any leftover data to the audio backend and
releasing all IO messages back to the guest. This is how according to
the spec the guest knows the release was successful.

For vhost-user devices, qemu can migrate the virtio state, but not the
back-end's internal state. To do so, we need to be able to transfer
this internal state between front-end (qemu) and back-end.
At this point, this new feature is added for the purpose of virtio-fs
migration. Because virtiofsd's internal state will not be too large, we
believe it is best to transfer it as a single binary blob after the
streaming phase.
These are the additions to the protocol:
- New vhost-user protocol feature VHOST_USER_PROTOCOL_F_DEVICE_STATE
- SET_DEVICE_STATE_FD function: Front-end and back-end negotiate a file
descriptor over which to transfer the state.
- CHECK_DEVICE_STATE: After the state has been transferred through the
file descriptor, the front-end invokes this function to verify
success. There is no in-band way (through the file descriptor) to
indicate failure, so we need to check explicitly.
Once the transfer FD has been established via SET_DEVICE_STATE_FD
(which includes establishing the direction of transfer and migration
phase), the sending side writes its data into it, and the reading side
reads it until it sees an EOF. Then, the front-end will check for
success via CHECK_DEVICE_STATE, which on the destination side includes
checking for integrity (i.e. errors during deserialization).

In vDPA, GET_VRING_BASE does not stop the queried vring, which is why
SUSPEND was introduced so that the returned index would be stable. In
vhost-user, it does stop the vring, so under the same reasoning, it can
get away without SUSPEND.
Still, we do want to clarify that if the device is completely stopped,
i.e. all vrings are stopped, the back-end should cease to modify any
state relating to the guest. Do this by calling it "suspended".

Currently, the vhost-user documentation says that rings are to be
initialized in a disabled state when VHOST_USER_F_PROTOCOL_FEATURES is
negotiated. However, by the time of feature negotiation, all rings have
already been initialized, so it is not entirely clear what this means.
At least the vhost-user-backend Rust crate's implementation interpreted
it to mean that whenever this feature is negotiated, all rings are to
put into a disabled state, which means that every SET_FEATURES call
would disable all rings, effectively halting the device. This is
problematic because the VHOST_F_LOG_ALL feature is also set or cleared
this way, which happens during migration. Doing so should not halt the
device.
Other implementations have interpreted this to mean that the device is
to be initialized with all rings disabled, and a subsequent SET_FEATURES
call that does not set VHOST_USER_F_PROTOCOL_FEATURES will enable all of
them. Here, SET_FEATURES will never disable any ring.
This interpretation does not suffer the problem of unintentionally
halting the device whenever features are set or cleared, so it seems
better and more reasonable.
We can clarify this in the documentation by making it explicit that the
enabled/disabled state is tracked even while the vring is stopped.
Every vring is initialized in a disabled state, and SET_FEATURES without
VHOST_USER_F_PROTOCOL_FEATURES simply becomes one way to enable all
vrings.

Provides a display option, zoom-to-fit, that enables scaling of the
display when full-screen mode is enabled.
Also ensures that the corresponding menu item is marked as enabled when
the option is set to on.

The first time gd_egl_scanout_texture() is called, there's a possibility
that the GTK drawing area might not be realized yet, in which case its
associated GdkWindow is NULL. This means gd_egl_init() was also skipped
and the EGLContext and EGLSurface stored in the VirtualGfxConsole are
not valid yet.
Continuing with the scanout in this conditions would result in hitting
an assert in libepoxy: "Couldn't find current GLX or EGL context".
A possible workaround is to just ignore the scanout request, giving the
the GTK drawing area some time to finish its realization. At that point,
the gd_egl_init() will succeed and the EGLContext and EGLSurface stored
in the VirtualGfxConsole will be valid.

The CPU HPA is in the high F-region on PA2.0 CPUs, so use F_EXTEND()
to trigger interrupt request at the right CPU HPA address.
Note that the cpu_hpa value comes out of the IRT, which doesn't store the
higher addresss bits.

The previous decoding misnamed the bit it called "local".
Other than the name, the implementation was correct for pa1.x.
Rename this field to "tlbe".
PA2.0 adds (a real) local bit to PxTLB, and also adds a range
of pages to flush in GR[b].
