2710d49a7c hw/pci-bridge/cxl_upstream: Move defintion of device to header. 
To avoid repetition of switch upstream port specific data in the
CXLDeviceState structure it will be necessary to access the switch USP
specific data from mailbox callbacks. Hence move it to cxl_device.h so it
is no longer an opaque structure.

c9460561ed hw/cxl/mbox: Generalize the CCI command processing 
By moving the parts of the mailbox command handling that are CCI type
specific out to the caller, make the main handling code generic. Rename it
to cxl_process_cci_message() to reflect this new generality.

Change the type3 mailbox handling (reused shortly for the switch
mailbox CCI) to take a snapshot of the mailbox input data rather
than operating on it in place.  This reduces the chance of bugs
due to aliasing going forwars.

cac36a8faf hw/cxl/mbox: Pull the CCI definition out of the CXLDeviceState 
Enables having multiple CCIs per devices. Each CCI (mailbox) has it's own
state and command list, so they can't share a single structure.

6f59274e93 hw/cxl/mbox: Split mailbox command payload into separate input and output 
New CCI types that will be supported shortly do not have a single buffer
used in both directions. As such, split it up. To avoid the complexities
of implementing all commands to handle potential aliasing, take a copy of
the input before use.

a7bb53b1ee hw/cxl/mbox: Pull the payload out of struct cxl_cmd and make instances constant 
Putting the pointer in the structure for command handling puts a single
variable element inside an otherwise constant structure. Move it out as
a directly passed variable and take the cxl_cmd structures constant.

45234c2dd2 hw/cxl: Fix a QEMU_BUILD_BUG_ON() in switch statement scope issue. 
As _Static_assert is a declaration, it can't follow a label until C23.
Some older versions of GCC trip up on this one.

This check has no obvious purpose so just remove it.

b342489ae7 hw/cxl: Line length reductions 
Michael Tsirkin observed that there were some unnecessarily
long lines in the CXL code in a recent review.
This patch is intended to rectify that where it does not
hurt readability.

388d6b574e hw/cxl: Use switch statements for read and write of cachemem registers 
Establishing that only register accesses of size 4 and 8 can occur
using these functions requires looking at their callers. Make it
easier to see that by using switch statements.
Assertions are used to enforce that the register storage is of the
matching size, allowing fixed values to be used for divisors of
the array indices.

198eee0cc1 tests: bios-tables-test: Add test for smbios type4 thread count2 
This tests the commit 7298fd7de5 ("hw/smbios: Fix thread count in
type4").

In smbios_build_type_4_table() (hw/smbios/smbios.c), if the number of
threads in the socket is more than 255, then smbios type4 table encodes
threads per socket into the thread count2 field.

So for the topology in this case, there're the following considerations:
1. threads per socket should be more than 255 to ensure we could cover
   the thread count2 field.
2. The original bug was that threads per socket was miscalculated, so
   now we should configure as many topology levels as possible (multiple
   dies, no module since x86 hasn't supported it) to cover more general
   topology scenarios, to ensure that the threads per socket encoded in
   the thread count2 field is correct.
3. For the more general topology, we should also add "cpus" (presented
   threads for machine) and "maxcpus" (total threads for machine) to
   make sure that configuring unpluged CPUs in smp (cpus < maxcpus)
   does not affect the correctness of threads per socket for thread
   count2 field.

Note we don't consider the topology with multiple sockets since this
topology would create too many vCPUs (more than 255 threads per socket
with at least 2 sockets, which may cause the failure "Number of
hotpluggable cpus requested (*) exceeds the maximum cpus supported by
KVM (*) socket_accept failed: Resource temporarily unavailable"), and
the calculation of threads per socket has already been covered by
"thread count" test case.

Based on these considerations, select the topology as the follow:

-smp cpus=210,maxcpus=260,dies=2,cores=65,threads=2

The expected thread count2 = threads per socket = threads (2)
* cores (65) * dies (2) = 260.

7ee18dcef1 tests: bios-tables-test: Add test for smbios type4 thread count 
This tests the commit 7298fd7de5 ("hw/smbios: Fix thread count in
type4").

In smbios_build_type_4_table() (hw/smbios/smbios.c), if the number of
threads in the socket is not more than 255, then smbios type4 table
encodes threads per socket into the thread count field.

So for the topology in this case, there're the following considerations:
1. threads per socket should be not more than 255 to ensure we could
   cover the thread count field.
2. The original bug was that threads per socket was miscalculated, so
   now we should configure as many topology levels as possible (multiple
   sockets & dies, no module since x86 hasn't supported it) to cover
   more general topology scenarios, to ensure that the threads per
   socket encoded in the thread count field is correct.
3. For the more general topology, we should also add "cpus" (presented
   threads for machine) and "maxcpus" (total threads for machine) to
   make sure that configuring unpluged CPUs in smp (cpus < maxcpus)
   does not affect the correctness of threads per socket for thread
   count field.

Based on these considerations, select the topology as the follow:

-smp cpus=15,maxcpus=54,sockets=2,dies=3,cores=3,threads=3

The expected thread count = threads per socket = threads (3) * cores (3)
* dies (3) = 27.

6dc82e3222 tests: bios-tables-test: Extend smbios core count2 test to cover general topology 
The commit 196ea60a73 ("hw/smbios: Fix core count in type4") fixed
the miscalculation of cores per socket.

The original core count2 test (with the topology configured by
"-smp 275") didn't recognize that topology-related but because it just
created a special topology with only one socket and one die by default,
ignoring the effect of more topology levels (between socket and core) on
the cores per socket calculation.

So for the topology in this case, there're the following considerations:
1. cores per socket should be more than 255 to ensure we could cover
   the core count2 field.
2. The original bug was that cores per socket was miscalculated, so now
   we should include as many topology levels as possible (multiple
   sockets or 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 count2 field is correct.

Based on these considerations, select the topology with multiple dies:

-smp 260,dies=2,cores=130,threads=1

Note, here we doesn't configure multiple sockets to avoid the error
("kvm_init_vcpu: kvm_get_vcpu failed (*): Too many open files") if user
uses the default ulimit seeting on his machine.

And the cores per socket calculation for multiple sockets has already
been covered by the core count test case, so that only multiple dies
configuration is enough.

The expected core count2 = cores per socket = cores (130) * dies (2) =
260.

148a8a1d5f tests: bios-tables-test: Add test for smbios type4 core count 
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.

df210963a1 tests: bios-tables-test: Add test for smbios type4 count 
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).

d1fd2d3118 vdpa: Add SetSteeringEBPF method for NetClientState 
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.

d8d64acbec virtio-sound: implement audio capture (RX) 
To perform audio capture we duplicate the TX logic of the previous
commit with the following difference: we receive data from the QEMU
audio backend and write it in the virt queue IO buffers the guest sends
to QEMU. When they are full (i.e. they have `period_bytes` amount of
data) or when recording stops in QEMU's audio backend, the buffer is
returned to the guest by notifying it.

18a752810f virtio-sound: implement audio output (TX) 
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.

This patch adds a PCI wrapper device for the virtio-sound device.
It is necessary to instantiate a virtio-snd device in a guest.
All sound logic will be added to the virtio-snd device in the following
commits.

To add this device with a guest, you'll need a >=5.13 kernel compiled
with CONFIG_SND_VIRTIO=y, which at the time of writing most distros have
off by default.

Use with following flags in the invocation:

Pulseaudio:
  -audio driver=pa,model=virtio
  or
  -audio driver=pa,model=virtio,server=/run/user/1000/pulse/native
sdl:
  -audio driver=sdl,model=virtio
coreaudio (macos/darwin):
  -audio driver=coreaudio,model=virtio
etc.

bca3e2a138 vhost-user-fs: Implement internal migration 
A virtio-fs device's VM state consists of:
- the virtio device (vring) state (VMSTATE_VIRTIO_DEVICE)
- the back-end's (virtiofsd's) internal state

We get/set the latter via the new vhost operations to transfer migratory
state.  It is its own dedicated subsection, so that for external
migration, it can be disabled.

4a00d5d7f4 vhost: Add high-level state save/load functions 
vhost_save_backend_state() and vhost_load_backend_state() can be used by
vhost front-ends to easily save and load the back-end's state to/from
the migration stream.

Because we do not know the full state size ahead of time,
vhost_save_backend_state() simply reads the data in 1 MB chunks, and
writes each chunk consecutively into the migration stream, prefixed by
its length.  EOF is indicated by a 0-length chunk.

019233096c vhost-user.rst: Migrating back-end-internal state 
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).

a6e76dd3c3 vhost-user.rst: Introduce suspended state 
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".

eae69cc36b vhost-user.rst: Clarify enabling/disabling vrings 
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.

c7f2181661 vhost-user.rst: Improve [GS]ET_VRING_BASE doc 
GET_VRING_BASE does not mention that it stops the respective ring.  Fix
that.

Furthermore, it is not fully clear what the "base offset" these
commands' documentation refers to is; an offset could be many things.
Be more precise and verbose about it, especially given that these
commands use different payload structures depending on whether the vring
is split or packed.
