vring_get_region_caches() must be called with the RCU read lock
acquired. virtqueue_packed_drop_all() does not, and uses the
'caches' pointer. Fix that by using the RCU_READ_LOCK_GUARD()
macro.

Both virtqueue_packed_get_avail_bytes() and
virtqueue_split_get_avail_bytes() access the region cache, but
their caller also does. Simplify by having virtqueue_get_avail_bytes
calling both with RCU lock held, and passing the caches as argument.

Vhost-vdpa uses one device multiqueue queue (pairs) model. So we need
to classify the one time request (e.g SET_OWNER) and make sure those
request were only called once per device.
This is used for multiqueue support.

Unlike vhost-kernel, vhost-vdpa adapts a single device multiqueue
model. So we need to simply use virtqueue index as the vhost virtqueue
index. This is a must for multiqueue to work for vhost-vdpa.

This patch introduces a boolean for the device has control queue which
can accepts control command via network queue.
The first user would be the control virtqueue support for vhost.

From: Jason Wang <jasowang@redhat.com>
We assume there's no cvq in the past, this is not true when we need
control virtqueue support for vhost-user backends. So this patch
implements the control virtqueue support for vhost-net. As datapath,
the control virtqueue is also required to be coupled with the
NetClientState. The vhost_net_start/stop() are tweaked to accept the
number of datapath queue pairs plus the the number of control
virtqueue for us to start and stop the vhost device.

Most of the time, "queues" really means queue pairs. So this patch
switch to use "queue_pairs" to avoid confusion.

From: Jason Wang <jasowang@redhat.com>
This patch introduces a new field in the vhost_dev structure to record
the last virtqueue index for the virtio device. This will be useful
for the vhost backends with 1:N model to start or stop the device
after all the vhost_dev structures were started or stopped.

This patch implements the control virtqueue support for vhost. This
requires virtio-net to figure out the datapath queue pairs and control
virtqueue via is_datapath and pass the number of those two types
of virtqueues to vhost_net_start()/vhost_net_stop().

To: qemu-devel; +Cc: Peter Maydell, Jason Wang
From: Jason Wang <jasowang@redhat.com>
This patch implements the multiqueue support for vhost-vdpa. This is
done simply by reading the number of queue pairs from the config space
and initialize the datapath and control path net client.

From: Stefano Garzarella <sgarzare@redhat.com>
Commit 1e08fd0a46 ("vhost-vsock: SOCK_SEQPACKET feature bit support")
enabled the SEQPACKET feature bit.
This commit is released with QEMU 6.1, so if we try to migrate a VM where
the host kernel supports SEQPACKET but machine type version is less than
6.1, we get the following errors:
Features 0x130000002 unsupported. Allowed features: 0x179000000
Failed to load virtio-vhost_vsock:virtio
error while loading state for instance 0x0 of device '0000:00:05.0/virtio-vhost_vsock'
load of migration failed: Operation not permitted
Let's disable the feature bit for machine types < 6.1.
We add a new OnOffAuto property for this, called `seqpacket`.
When it is `auto` (default), QEMU behaves as before, trying to enable the
feature, when it is `on` QEMU will fail if the backend (vhost-vsock
kernel module) doesn't support it.
Fixes: 1e08fd0a46 ("vhost-vsock: SOCK_SEQPACKET feature bit support")

From: Stefano Garzarella <sgarzare@redhat.com>
virtio-vsock features, like VIRTIO_VSOCK_F_SEQPACKET, can be handled
by vhost-vsock-common parent class. In this way, we can reuse the
same code for all virtio-vsock backends (i.e. vhost-vsock,
vhost-user-vsock).
Let's move `seqpacket` property to vhost-vsock-common class, add
vhost_vsock_common_get_features() used by children, and disable
`seqpacket` for vhost-user-vsock device for machine types < 6.2.
The behavior of vhost-vsock device doesn't change; vhost-user-vsock
device now supports `seqpacket` property.

to build_header(), to prevent errors caused by it [1].
acpi_table_begin():
initializes table header and keeps track of
table data/offsets
acpi_table_end():
sets actual table length and tells bios loader
where table is for the later initialization on
guest side.

From: Igor Mammedov <imammedo@redhat.com>
it replaces error-prone pointer arithmetic for build_header() API,
with 2 calls to start and finish table creation,
which hides offsets magic from API user.
While at it switch to build_append_int_noprefix() to build
table entries tables.

From: Igor Mammedov <imammedo@redhat.com>
Instead of composing disabled _MAT entry and then later on
patching it to enabled for hotpluggbale CPUs in DSDT,
set it to enabled at the time _MAT entry is built.
It will allow to drop usage of packed structures in
following patches when build_madt() is switched to use
build_append_int_noprefix() API.

From: Igor Mammedov <imammedo@redhat.com>
implicit cast to structure uint8_t member didn't raise error when
assigning value from incorrect enum, but when using build_append_gas()
(next patch) it will error out with (clang):
implicit conversion from enumeration type 'AmlRegionSpace'
to different enumeration type 'AmlAddressSpace'
fix cast error by using correct AML_AS_SYSTEM_MEMORY enum

From: Igor Mammedov <imammedo@redhat.com>
it replaces error-prone pointer arithmetic for build_header() API,
with 2 calls to start and finish table creation,
which hides offsets magic from API user.
while at it, replace packed structure with endian agnostic
build_append_FOO() API.
PS:
Spec is Microsoft hosted, however 1.02 is no where to be found
(MS lists only the current revision) and the current revision is 1.07,
so bring comments in line with 1.07 as this is the only available spec.
There is no content change between originally implemented 1.02
(using QEMU code as reference) and 1.07. The only change is renaming
'Reserved2' field to 'Language', with the same 0 value.

From: Igor Mammedov <imammedo@redhat.com>
it replaces error-prone pointer arithmetic for build_header() API,
with 2 calls to start and finish table creation,
which hides offsets magic from API user.
while at it, replace packed structure with endian agnostic
build_append_FOO() API.

Change caf108bc58790 ("hw/i386/acpi-build: Add ACPI PCI hot-plug methods to Q35")

starts at address 0x0cc4 and ends at 0x0cdb. At the time when the patch was
written but the final version of the patch was not yet pushed upstream, this
address range was free and did not conflict with any other IO address ranges.
However, with the following change, this address range was no
longer conflict free as in this change, the IO address range
(value of ACPI_PCIHP_SIZE) was incremented by four bytes:
b32bd763a1ca92 ("pci: introduce acpi-index property for PCI device")
This can be seen from the output of QMP command 'info mtree' :
0000000000000600-0000000000000603 (prio 0, i/o): acpi-evt
0000000000000604-0000000000000605 (prio 0, i/o): acpi-cnt
0000000000000608-000000000000060b (prio 0, i/o): acpi-tmr
0000000000000620-000000000000062f (prio 0, i/o): acpi-gpe0
0000000000000630-0000000000000637 (prio 0, i/o): acpi-smi
0000000000000cc4-0000000000000cdb (prio 0, i/o): acpi-pci-hotplug
0000000000000cd8-0000000000000ce3 (prio 0, i/o): acpi-cpu-hotplug
It shows that there is a region of conflict between IO regions of acpi
pci hotplug and acpi cpu hotplug.
Unfortunately, the change caf108bc58790 did not update the IO address range
appropriately before it was pushed upstream to accommodate the increased
length of the IO address space introduced in change b32bd763a1ca92.
Due to this bug, windows guests complain 'This device cannot find
enough free resources it can use' in the device manager panel for extended
IO buses. This issue also breaks the correct functioning of pci hotplug as the
following shows that the IO space for pci hotplug has been truncated:
(qemu) info mtree -f
FlatView #0
AS "I/O", root: io
Root memory region: io
0000000000000cc4-0000000000000cd7 (prio 0, i/o): acpi-pci-hotplug
0000000000000cd8-0000000000000cf7 (prio 0, i/o): acpi-cpu-hotplug
Therefore, in this fix, we adjust the IO address range for the acpi pci
hotplug so that it does not conflict with cpu hotplug and there is no
truncation of IO spaces. The starting IO address of PCI hotplug region
has been decremented by four bytes in order to accommodate four byte
increment in the IO address space introduced by change
b32bd763a1ca92 ("pci: introduce acpi-index property for PCI device")
After fixing, the following are the corrected IO ranges:
0000000000000600-0000000000000603 (prio 0, i/o): acpi-evt
0000000000000604-0000000000000605 (prio 0, i/o): acpi-cnt
0000000000000608-000000000000060b (prio 0, i/o): acpi-tmr
0000000000000620-000000000000062f (prio 0, i/o): acpi-gpe0
0000000000000630-0000000000000637 (prio 0, i/o): acpi-smi
0000000000000cc0-0000000000000cd7 (prio 0, i/o): acpi-pci-hotplug
0000000000000cd8-0000000000000ce3 (prio 0, i/o): acpi-cpu-hotplug
This change has been tested using a Windows Server 2019 guest VM. Windows
no longer complains after this change.

We have modified the IO address range for ACPI pci hotplug in q35. See change:
5adcc9e39e6a5 ("hw/i386/acpi: fix conflicting IO address range for acpi pci hotplug in q35")
The ACPI DSDT table golden blobs must be regenrated in order to make the unit tests
pass. This change updates the golden ACPI DSDT table blobs.
Following is the ASL diff between the blobs:

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>
The subsection name for page-poison was typo'd as:
vitio-balloon-device/page-poison
Note the missing 'r' in virtio.
When we have a machine type that enables page poison, and the guest
enables it (which needs a new kernel), things fail rather unpredictably.
The fallout from this is that most of the other subsections fail to
load, including things like the feature bits in the device, one
possible fallout is that the physical addresses of the queues
then get aligned differently and we fail with an error about
last_avail_idx being wrong.
It's not obvious to me why this doesn't produce a more obvious failure,
but virtio's vmstate loading is a bit open-coded.
Fixes: 7483cbbaf82 ("virtio-balloon: Implement support for page poison reporting feature")

Per 'QEMU Coding Style':
Naming
======
Variables are lower_case_with_underscores; easy to type and read.
Rename amdviPCI variable as amdvi_pci.
amdviPCI_register_types() register more than PCI types:
TYPE_AMD_IOMMU_DEVICE inherits TYPE_X86_IOMMU_DEVICE which
itself inherits TYPE_SYS_BUS_DEVICE.
Rename it more generically as amdvi_register_types().

Various functions are SysBus specific. Rename them using the
consistent amdvi_sysbus_XXX() pattern, to differentiate them
from PCI specific functions (which we'll add in the next
commit).

TYPE_AMD_IOMMU_PCI is user-creatable but not well described.
Implement its class_init() handler to add it to the 'Misc
devices' category, and add a description.
