Aspeed SoCs use a single CPU type (set as AspeedSoCClass::cpu_type).
Convert it to a NULL-terminated array (of a single non-NULL element).
Set MachineClass::valid_cpu_types[] to use the common machine code
to provide hints when the requested CPU is invalid (see commit
e702cbc19e ("machine: Improve is_cpu_type_supported()").

In cases where a device tries to read more bytes than the block device
contains, the error is vague: "device requires X bytes, block backend
provides Y bytes".
This patch changes the errors of this function to include the block

This patch implements a 32 half word FIFO as per imx serial device
specifications. If a non empty FIFO is below the trigger level, an
ageing timer will tick for a duration of 8 characters. On expiry,
AGTIM will be set triggering an interrupt. AGTIM timer resets when
there is activity in the receive FIFO.
Otherwise, RRDY is set when trigger level is exceeded. The receive
trigger level is 8 in newer kernel versions and 1 in older ones.
This change will break migration compatibility for the imx boards.

Add MMDC, OCOTP, SQPI, CAAM, and USBMISC as unimplemented devices.
This allows operating systems such as Linux to run emulations such as
mcimx6ul-evk.
Before commit 0cd4926b85 ("Refactor i.MX6UL processor code"), the affected
memory ranges were covered by the unimplemented DAP device. The commit
reduced the DAP address range from 0x100000 to 4kB, and the emulation
thus no longer covered the various unimplemented devices in the affected
address range.

The dataplane code used to be significantly different from the
non-dataplane code and therefore had a separate source file.
Over time the difference has gotten smaller because the I/O code paths
were unified. Nowadays the distinction between the VirtIOBlock and
VirtIOBlockDataPlane structs is more of an inconvenience that hinders
code simplification.
Move hw/block/dataplane/virtio-blk.c into hw/block/virtio-blk.c, merging
VirtIOBlockDataPlane's fields into VirtIOBlock.
hw/block/virtio-blk.c used VirtIOBlock->dataplane to check if
virtio_blk_data_plane_create() was successful. This is not necessary
because ->dataplane_started and ->dataplane_disabled can be used
instead. This patch makes those changes in order to drop
VirtIOBlock->dataplane.

The current logic does not check for this condition, resulting in
the incorrect assignment of 'lowaddr' as zero.
There is already a piece of codes inside the segment traversal loop
that checks for zero-sized loadable segments for not creating empty
ROM blobs. Let's move this check to the beginning of the loop to
cover both scenarios.

ISM devices are sensitive to manipulation of the IOMMU, so the ISM device
needs to be reset before the vfio-pci device is reset (triggering a full
UNMAP). In order to ensure this occurs, trigger ISM device resets from
subsystem_reset before triggering the PCI bus reset (which will also
trigger vfio-pci reset). This only needs to be done for ISM devices
which were enabled for use by the guest.
Further, ensure that AIF is disabled as part of the reset event.

On LoongArch physical machine, one extioi interrupt controller only
supports 4 cpus. With processor more than 4 cpus, there are multiple
extioi interrupt controllers; if interrupts need to be routed to
other cpus, they are forwarded from extioi node0 to other extioi nodes.
On virt machine model, there is simple extioi interrupt device model.
All cpus can access register of extioi interrupt controller, however
interrupt can only be route to 4 vcpu for compatible with old kernel.
This patch adds dynamic cpu number support about extioi interrupt.
With old kernel legacy extioi model is used, however kernel can detect
and choose new route method in future, so that interrupt can be routed to
all vcpus.

LoongArch system has iocsr address space, most iocsr registers are
per-board, however some iocsr register spaces banked for percpu such
as ipi mailbox and extioi interrupt status. For banked iocsr space,
each cpu has the same iocsr space, but separate data.
This patch changes iocsr address space per-board rather percpu,
for iocsr registers specified for cpu, MemTxAttrs.requester_id
can be parsed for the cpu. With this patches, the total address space
on board will be simple, only iocsr address space and system memory,
rather than the number of cpu and system memory.

ACPI DSDT generator needs information like ECAM range, PIO range, 32-bit
and 64-bit PCI MMIO range etc related to the PCI host bridge. Instead of
making these values machine specific, create properties for the GPEX
host bridge with default value 0. During initialization, the firmware
can initialize these properties with correct values for the platform.
This basically allows DSDT generator code independent of the machine
specific memory map accesses.

Move vfio_spapr_container_setup() to a VFIOIOMMUClass::setup handler
and convert the sPAPR VFIOIOMMUOps struct to a QOM interface. The
sPAPR QOM interface inherits from the legacy QOM interface because
because both have the same basic needs. The sPAPR interface is then
extended with the handlers specific to the sPAPR IOMMU.
This allows reuse and provides better abstraction of the backends. It
will be useful to avoid compiling the sPAPR IOMMU backend on targets
not supporting it.

VFIOContainerBase was not introduced as an abstract QOM object because
it felt unnecessary to expose all the IOMMU backends to the QEMU
machine and human interface. However, we can still abstract the IOMMU
backend handlers using a QOM interface class. This provides more
flexibility when referencing the various implementations.
Simply transform the VFIOIOMMUOps struct in an InterfaceClass and do
some initial name replacements. Next changes will start converting
VFIOIOMMUOps.

before stopping the VM at the source. The main goal is to reduce the
downtime.
However, the destination QEMU is unaware of which vhost_vdpa device will
register its memory_listener. If the source guest has CVQ enabled, it
will be the CVQ device. Otherwise, it will be the first one.
Move the iova range to VhostVDPAShared so all vhost_vdpa can use it,
rather than always in the first or last vhost_vdpa.

It will hold properties shared among all vhost_vdpa instances associated
with of the same device. For example, we just need one iova_tree or one
memory listener for the entire device.
Next patches will register the vhost_vdpa memory listener at the
beginning of the VM migration at the destination. This enables QEMU to
map the memory to the device before stopping the VM at the source,
instead of doing while both source and destination are stopped, thus
minimizing the downtime.
However, the destination QEMU is unaware of which vhost_vdpa struct will
register its memory_listener. If the source guest has CVQ enabled, it
will be the one associated with the CVQ. Otherwise, it will be the

Save the memory operations related members in a common place rather than
always in the first / last vhost_vdpa.

This adds support for vhost-scsi to be able to create a worker thread
per virtqueue. Right now for vhost-net we get a worker thread per
tx/rx virtqueue pair which scales nicely as we add more virtqueues and
CPUs, but for scsi we get the single worker thread that's shared by all
virtqueues. When trying to send IO to more than 2 virtqueues the single
thread becomes a bottlneck.
This patch adds a new setting, worker_per_virtqueue, which can be set
to:
false: Existing behavior where we get the single worker thread.
true: Create a worker per IO virtqueue.

Add the iothread-vq-mapping parameter to assign virtqueues to IOThreads.
Store the vq:AioContext mapping in the new struct
VirtIOBlockDataPlane->vq_aio_context[] field and refactor the code to
use the per-vq AioContext instead of the BlockDriverState's AioContext.
Reimplement --device virtio-blk-pci,iothread= and non-IOThread mode by
assigning all virtqueues to the IOThread and main loop's AioContext in
vq_aio_context[], respectively.
The comment in struct VirtIOBlockDataPlane about EventNotifiers is

virtio-blk and virtio-scsi devices will need a way to specify the
mapping between IOThreads and virtqueues. At the moment all virtqueues
are assigned to a single IOThread or the main loop. This single thread
can be a CPU bottleneck, so it is necessary to allow finer-grained
assignment to spread the load.
Introduce DEFINE_PROP_IOTHREAD_VQ_MAPPING_LIST() so devices can take a
parameter that maps virtqueues to IOThreads. The command-line syntax for
this new property is as follows:
--device '{"driver":"foo","iothread-vq-mapping":[{"iothread":"iothread0","vqs":[0,1,2]},...]}'
IOThreads are specified by name and virtqueues are specified by 0-based
index.
It will be common to simply assign virtqueues round-robin across a set
of IOThreads. A convenient syntax that does not require specifying
individual virtqueue indices is available:
--device '{"driver":"foo","iothread-vq-mapping":[{"iothread":"iothread0"},{"iothread":"iothread1"},...]}'

qdev_alias_all_properties() aliases a DeviceState's qdev properties onto
an Object. This is used for VirtioPCIProxy types so that --device
virtio-blk-pci has properties of its embedded --device virtio-blk-device
object.
Currently this function is implemented using qdev properties. Change the
function to use QOM object class properties instead. This works because
qdev properties create QOM object class properties, but it also catches
any QOM object class-only properties that have no qdev properties.
This change ensures that properties of devices are shown with --device
foo,\? even if they are QOM object class properties.

Protect the Task Management Function BH state with a lock. The TMF BH
runs in the main loop thread. An IOThread might process a TMF at the
same time as the TMF BH is running. Therefore tmf_bh_list and tmf_bh
must be protected by a lock.
Run TMF request completion in the IOThread using aio_wait_bh_oneshot().
This avoids more locking to protect the virtqueue and SCSI layer state.

Stop depending on the AioContext lock and instead access
SCSIDevice->requests from only one thread at a time:
- When the VM is running only the BlockBackend's AioContext may access
the requests list.
- When the VM is stopped only the main loop may access the requests
list.
These constraints protect the requests list without the need for locking
in the I/O code path.
Note that multiple IOThreads are not supported yet because the code
assumes all SCSIRequests are executed from a single AioContext. Leave
that as future work.

High memory space is aligned with 256M, it will be better if it is

QOM type names containing ',' result in awful UI. We got rid of them
in v6.0.0 (commit e178113ff6 hw: Replace anti-social QOM type names).
A few have crept back since:
xlnx,cframe-reg
xlnx,efuse
xlnx,pmc-efuse-cache
xlnx,versal-cfu-apb
xlnx,versal-cfu-fdro
xlnx,versal-cfu-sfr
xlnx,versal-crl
xlnx,versal-efuse
xlnx,zynqmp-efuse
These are all device types. They can't be plugged with -device /
device_add, except for "xlnx,efuse" (I'm not sure that one is
intentional).
They *can* be used with -device / device_add to request help.
Usability is poor, though: you have to double the comma, like this:
$ qemu-system-aarch64 -device xlnx,,pmc-efuse-cache,help
They can also be used with -global, where you must *not* double the
comma:
$ qemu-system-aarch64 -global xlnx,efuse.drive-index=2
Trap for the unwary.
"xlnx,efuse", "xlnx,versal-efuse", "xlnx,pmc-efuse-cache",
"xlnx-zynqmp-efuse" are from v6.2.0, "xlnx,versal-crl" is from v7.1.0,
and the remainder are new.
Rename them all to "xlnx-FOO", like commit e178113ff6 did.

This gives management tools like libvirt a chance to open the vfio
cdev with privilege and pass FD to qemu. This way qemu never needs
to have privilege to open a VFIO or iommu cdev node.
Together with the earlier support of pre-opening /dev/iommu device,
now we have full support of passing a vfio device to unprivileged
qemu by management tool. This mode is no more considered for the
legacy backend. So let's remove the "TODO" comment.
Add helper functions vfio_device_set_fd() and vfio_device_get_name()
to set fd and get device name, they will also be used by other vfio
devices.
There is no easy way to check if a device is mdev with FD passing,
so fail the x-balloon-allowed check unconditionally in this case.
There is also no easy way to get BDF as name with FD passing, so
we fake a name by VFIO_FD[fd].

The VIA integrated south bridge chips combine several functions and
allow routing their interrupts to any of the ISA IRQs also allowing
multiple sources to share the same ISA IRQ. E.g. pegasos2 firmware
configures everything to use IRQ 9 but amigaone routes them to
separate ISA IRQs so the current simplified routing does not work.
Bring back via_isa_set_irq() and change it to take the component that
wants to change an IRQ and keep track of interrupt status of each
source separately and do the mapping to ISA IRQ within the ISA bridge.
This may not handle cases when an ISA IRQ is controlled by devices
directly, not going through via_isa_set_irq() such as serial, parallel
or keyboard but these IRQs being conventionally fixed are not likely
to be change by guests or share with other devices so this does not
cause a problem in practice.
This reverts commit 4e5a20b6da.

This function reads the value of the PCI_CLASS_PROG register for PCI IDE
controllers and configures the PCI BARs and/or IDE ioports accordingly.
In the case where we switch to legacy mode, the PCI BARs are set to return zero
(as suggested in the "PCI IDE Controller" specification), the legacy IDE ioports
are enabled, and the PCI interrupt pin cleared to indicate legacy IRQ routing.
Conversely when we switch to native mode, the legacy IDE ioports are disabled
and the PCI interrupt pin set to indicate native IRQ routing. The contents of
the PCI BARs are unspecified, but this is not an issue since if a PCI IDE
controller has been switched to native mode then its BARs will need to be
programmed.

Until now, array properties are actually implemented with a hack that
uses multiple properties on the QOM level: a static "foo-len" property
and after it is set, dynamically created "foo[i]" properties.
In external interfaces (-device on the command line and device_add in
QMP), this interface was broken by commit f3558b1b ('qdev: Base object
creation on QDict rather than QemuOpts') because QDicts are unordered
and therefore it could happen that QEMU tried to set the indexed
properties before setting the length, which fails and effectively makes
array properties inaccessible. In particular, this affects the 'ports'
property of the 'rocker' device, which used to be configured like this:
-device rocker,len-ports=2,ports[0]=dev0,ports[1]=dev1
This patch reworks the external interface so that instead of using a
separate top-level property for the length and for each element, we use
a single true array property that accepts a list value. In the external
interfaces, this is naturally expressed as a JSON list and makes array
properties accessible again. The new syntax looks like this:
-device '{"driver":"rocker","ports":["dev0","dev1"]}'
Creating an array property on the command line without using JSON format
is currently not possible. This could be fixed by switching from
QemuOpts to a keyval parser, which however requires consideration of the
compatibility implications.
All internal users of devices with array properties go through
qdev_prop_set_array() at this point, so updating it takes care of all of
them.

Having two functions with the same name is a bad idea. As spapr only
uses the function locally, made it static.

Power9 is supposed to have 4 PIB-connected I2C engines with the
following number of ports on each engine:
0: 2
1: 13
2: 2
3: 2
Power10 also has 4 engines but has the following number of ports
on each engine:
0: 14
1: 14
2: 2
3: 16
Current code assumes that they all have the same (maximum) number.
This can be a problem if software expects to see a certain number
of ports present (Power Hypervisor seems to care).
Fixed this by adding separate tables for power9 and power10 that
map the I2C controller number to the number of I2C buses that should
be attached for that engine.

The more recent IBM power processors have an embedded I2C
controller that is accessible by software via the XSCOM
address space.
Each instance of the I2C controller is capable of controlling
multiple I2C buses (one at a time). Prior to beginning a
transaction on an I2C bus, the bus must be selected by writing
the port number associated with the bus into the PORT_NUM
field of the MODE register. Once an I2C bus is selected,
the status of the bus can be determined by reading the
Status and Extended Status registers.
I2C bus transactions can be started by writing a command to
the Command register and reading/writing data from/to the
FIFO register.
Not supported :
. 10 bit I2C addresses
. Multimaster
. Slave

VOUT_MODE has a three bit mode and 4 bit parameter, the three bit
mode determines whether voltages are formatted as uint16, uint16,
VID, and Direct modes. VID and Direct modes use the remaining 5 bits
