7f863302bd virtio-net: support queue_enable
Support queue_enable in vhost-kernel scenario. It can be called when
a vq reset operation has been performed and the vq is restared.

It should be noted that we can restart the vq when the vhost has
already started. When launching a new vhost device, the vhost is not
started and all vqs are not initalized until VIRTIO_PCI_COMMON_STATUS
is written. Thus, we should use vhost_started to differentiate the
two cases: vq reset and device start.

Currently it only supports vhost-kernel.

7dc6be52f4 virtio-net: support queue reset
virtio-net and vhost-kernel implement queue reset.
Queued packets in the corresponding queue pair are flushed
or purged.

For virtio-net, userspace datapath will be disabled later in
__virtio_queue_reset(). It will set addr of vring to 0 and idx to 0.
Thus, virtio_net_receive() and virtio_net_flush_tx() will not receive
or send packets.

For vhost-net, the datapath will be disabled in vhost_net_virtqueue_reset().

10f8a115a8 vhost-net: vhost-kernel: introduce vhost_net_virtqueue_restart()
Introduce vhost_net_virtqueue_restart(), which can restart the
specific virtqueue when the vhost net started running before.
If it fails to restart the virtqueue, the device will be stopped.

Here we do not reuse vhost_net_start_one() or vhost_dev_start()
because they work at queue pair level. The mem table and features
do not change, so we can call the vhost_virtqueue_start() to
restart a specific queue.

This patch only considers the case of vhost-kernel, when
NetClientDriver is NET_CLIENT_DRIVER_TAP.

c2daa08e17 vhost-net: vhost-kernel: introduce vhost_net_virtqueue_reset()
Introduce vhost_virtqueue_reset(), which can reset the specific
virtqueue in the device. Then it will unmap vrings and the desc
of the virtqueue.

Here we do not reuse the vhost_net_stop_one() or vhost_dev_stop(),
because they work at queue pair level. We do not use
vhost_virtqueue_stop() because it may stop the device in the
backend.

This patch only considers the case of vhost-kernel, when
NetClientDriver is NET_CLIENT_DRIVER_TAP.

Furthermore, we do not need net->nc->info->poll() because
it enables userspace datapath and we want to stop all
datapaths for this reset virtqueue here.

805d782d28 virtio-pci: support queue reset
PCI devices support vq reset.

Based on this function, the driver can adjust the size of the ring, and
quickly recycle the buffer in the ring.

The migration of the virtio devices will not happen during a reset
operation. This is becuase the global iothread lock is held. Migration
thread also needs the lock. As a result, when migration of virtio
devices starts, the 'reset' status of VirtIOPCIQueue will always be 0.
Thus, we do not need to add it in vmstate_virtio_pci_modern_queue_state.

e72cfabf4e hw/virtio/virtio-iommu-pci: Enforce the device is plugged on the root bus
In theory the virtio-iommu-pci could be plugged anywhere in the PCIe
topology and as long as the dt/acpi info are properly built this should
work. However at the moment we fail to do that because the
virtio-iommu-pci BDF is not computed at plug time and in that case
vms->virtio_iommu_bdf gets an incorrect value.

For instance if the virtio-iommu-pci is plugged onto a pcie root port
and the virtio-iommu protects a virtio-block-pci device the guest does
not boot.

So let's do not pretend we do support this case and fail the initialize()
if we detect the virtio-iommu-pci is plugged anywhere else than on the
root bus. Anyway this ability is not needed.

f5ee7413d5 hw/mem/cxl-type3: Add CXL CDAT Data Object Exchange
The CDAT can be specified in two ways. One is to add ",cdat=<filename>"
in "-device cxl-type3"'s command option. The file is required to provide
the whole CDAT table in binary mode. The other is to use the default
that provides some 'reasonable' numbers based on type of memory and
size.

The DOE capability supporting CDAT is added to hw/mem/cxl_type3.c with
capability offset 0x190. The config read/write to this capability range
can be generated in the OS to request the CDAT data.

5fb52f6cc8 hw/pci: PCIe Data Object Exchange emulation
Emulation of PCIe Data Object Exchange (DOE)
PCIE Base Specification r6.0 6.3 Data Object Exchange

Supports multiple DOE PCIe Extended Capabilities for a single PCIe
device. For each capability, a static array of DOEProtocol should be passed
to pcie_doe_init(). The protocols in that array will be registered under
the DOE capability structure. For each protocol, vendor ID, type, and
corresponding callback function (handle_request()) should be implemented.
This callback function represents how the DOE request for corresponding
protocol will be handled.

pcie_doe_{read/write}_config() must be appended to corresponding PCI
device's config_read/write() handler to enable DOE access. In
pcie_doe_read_config(), false will be returned if pci_config_read()
offset is not within DOE capability range. In pcie_doe_write_config(),
the function will have no affect if the address is not within the related
DOE PCIE extended capability.

4496d1d3eb acpi: fadt: support revision 6.0 of the ACPI specification
Update the Fixed ACPI Description Table (FADT) to revision 6.0 of the ACPI
specification adding the field "Hypervisor Vendor Identity".

This field's description states the following: "64-bit identifier of hypervisor
vendor. All bytes in this field are considered part of the vendor identity.
These identifiers are defined independently by the vendors themselves,
usually following the name of the hypervisor product. Version information
should NOT be included in this field - this shall simply denote the vendor's
name or identifier. Version information can be communicated through a
supplemental vendor-specific hypervisor API. Firmware implementers would
place zero bytes into this field, denoting that no hypervisor is present in
the actual firmware."

77a8e24c5b acpi/tests/avocado/bits: add acpi and smbios avocado tests that uses biosbits
This introduces QEMU acpi/smbios biosbits avocado test which is run
from within the python virtual environment. When the bits tests are run, bits
binaries are downloaded from an external repo/location, bios bits iso is
regenerated containing the acpi/smbios bits tests that are maintained as a part
of the QEMU source under tests/avocado/acpi-bits/bits-test . When the VM is
spawned with the iso, it runs the tests in batch mode and the results are pushed
out from the VM to the test machine where they are analyzed by this script and
pass/fail results are reported.

91cab435ec acpi/tests/avocado/bits: disable acpi PSS tests that are failing in biosbits
PSS tests in acpi test suite seems to be failing in biosbits. This is because
the test is unable to find PSS support in QEMU bios. Let us disable
them for now so that make check does not fail. We can fix the tests and
re-enable them later.

Example failure:

---- ACPI _PSS (Pstate) table conformance tests ----
[assert] _PSS must exist FAIL
  \_SB_.CPUS.C000
  No _PSS exists
Summary: 1 passed, 1 failed
---- ACPI _PSS (Pstate) runtime tests ----
[assert] _PSS must exist FAIL
  \_SB_.CPUS.C000
  No _PSS exists
Summary: 0 passed, 1 failed

87853babb3 acpi/tests/avocado/bits: initial commit of test scripts that are run by biosbits
This is initial commit of cpuid, acpi and smbios python test scripts for
biosbits to execute. No change has been made to them from the original code
written by the biosbits author Josh Triplett. They are required to be installed
into the bits iso file and then run from within the virtual machine booted off
with biosbits iso.

The test scripts have a ".py2" extension in order to prevent avocado from
loading them. They are written in python 2.7 and are run from within bios bits.
There is no need for avocado to try to load them and call out errors on python3
specific syntaxes.

The original location of these tests are here:
https://github.com/biosbits/bits/blob/master/python/testacpi.py
https://github.com/biosbits/bits/blob/master/python/smbios.py
https://github.com/biosbits/bits/blob/master/python/testcpuid.py

For QEMU, we maintain a fork of the above repo here with numerious fixes:
https://gitlab.com/qemu-project/biosbits-bits

The acpi test for example is maintained here in the fork:
https://gitlab.com/qemu-project/biosbits-bits/-/raw/master/python/testacpi.py

4ad44f624b acpi/nvdimm: Implement ACPI NVDIMM Label Methods
Recent ACPI spec [1] has defined NVDIMM Label Methods _LS{I,R,W}, which
deprecates corresponding _DSM Functions defined by PMEM _DSM Interface spec
[2].

Since the semantics of the new Label Methods are almost same as old _DSM
methods, the implementations here simply wrapper old ones.

ASL form diff can be found in next patch of updating golden master
binaries.

NVDIMM_DEVICE_DSM_UUID for "4309AC30-0D11-11E4-9191-0800200C9A66", which is
NVDIMM device specific method uuid defined in NVDIMM _DSM interface spec,
Section 3. [1]

63bb20d669 acpi/ssdt: Fix aml_or() and aml_and() in if clause
In If condition, using bitwise and/or, rather than logical and/or.

The result change in AML code:

If (((Local6 == Zero) | (Arg0 != Local0)))
==>
If (((Local6 == Zero) || (Arg0 != Local0)))

If (((ObjectType (Arg3) == 0x04) & (SizeOf (Arg3) == One)))
==>
If (((ObjectType (Arg3) == 0x04) && (SizeOf (Arg3) == One)))

4ad08e8a57 hw/i386/e820: remove legacy reserved entries for e820
e820 reserved entries were used before the dynamic entries with fw config files
were intoduced. Please see the following change:
7d67110f2d9a6("pc: add etc/e820 fw_cfg file")

Identical support was introduced into seabios as well with the following commit:
ce39bd4031820 ("Add support for etc/e820 fw_cfg file")

Both the above commits are now quite old. QEMU machines 1.7 and newer no longer
use the reserved entries. Seabios uses fw config files and
dynamic e820 entries by default and only falls back to using reserved entries
when it has to work with old qemu (versions earlier than 1.7). Please see
functions qemu_cfg_e820() and qemu_early_e820(). It is safe to remove legacy
FW_CFG_E820_TABLE and associated code now as QEMU 7.0 has deprecated i440fx
machines 1.7 and older. It would be incredibly rare to run the latest qemu
version with a very old version of seabios that did not support fw config files
for e820.

As far as I could see, edk2/ovfm never supported reserved entries and uses fw
config files from the beginning. So there should be no incompatibilities with
ovfm as well.

4e4fa6c12d accel/tcg: Complete cpu initialization before registration
Delay cpu_list_add until realize is complete, so that cross-cpu
interaction does not happen with incomplete cpu state.  For this,
we must delay plugin initialization out of tcg_exec_realizefn,
because no cpu_index has been assigned.

Fixes a problem with cross-cpu jump cache flushing, when the
jump cache has not yet been allocated.

Fixes: a976a99a29 ("include/hw/core: Create struct CPUJumpCache")

cc30dc441b target/openrisc: Use cpu_unwind_state_data for mfspr
Since we do not plan to exit, use cpu_unwind_state_data
and extract exactly the data requested.

This is a bug fix, in that we no longer clobber dflag.

Consider:

        l.j       L2         // branch
        l.mfspr   r1, ppc    // delay

L1:     boom
L2:     l.lwa     r3, (r4)

Here, dflag would be set by cpu_restore_state (because that is the current
state of the cpu), but but not cleared by tb_stop on exiting the TB
(because DisasContext has recorded the current value as zero).

The next TB begins at L2 with dflag incorrectly set.  If the load has a
tlb miss, then the exception will be delivered as per a delay slot:
with DSX set in the status register and PC decremented (delay slots
restart by re-executing the branch). This will cause the return from
interrupt to go to L1, and boom!
