Add support to virtio-pci devices for handling the extra data sent
from the driver to the device when the VIRTIO_F_NOTIFICATION_DATA
transport feature has been negotiated.
The extra data that's passed to the virtio-pci device when this
feature is enabled varies depending on the device's virtqueue
layout.
In a split virtqueue layout, this data includes:
- upper 16 bits: shadow_avail_idx
- lower 16 bits: virtqueue index
In a packed virtqueue layout, this data includes:
- upper 16 bits: 1-bit wrap counter & 15-bit shadow_avail_idx
- lower 16 bits: virtqueue index

On setups with one or more virtio-net devices with vhost on,
dirty tracking iteration increases cost the bigger the number
amount of queues are set up e.g. on idle guests migration the
following is observed with virtio-net with vhost=on:
48 queues -> 78.11% [.] vhost_dev_sync_region.isra.13
8 queues -> 40.50% [.] vhost_dev_sync_region.isra.13
1 queue -> 6.89% [.] vhost_dev_sync_region.isra.13
2 devices, 1 queue -> 18.60% [.] vhost_dev_sync_region.isra.14
With high memory rates the symptom is lack of convergence as soon
as it has a vhost device with a sufficiently high number of queues,
the sufficient number of vhost devices.
On every migration iteration (every 100msecs) it will redundantly
query the *shared log* the number of queues configured with vhost
that exist in the guest. For the virtqueue data, this is necessary,
but not for the memory sections which are the same. So essentially
we end up scanning the dirty log too often.
To fix that, select a vhost device responsible for scanning the
log with regards to memory sections dirty tracking. It is selected
when we enable the logger (during migration) and cleared when we
disable the logger. If the vhost logger device goes away for some
reason, the logger will be re-selected from the rest of vhost
devices.
After making mem-section logger a singleton instance, constant cost
of 7%-9% (like the 1 queue report) will be seen, no matter how many
queues or how many vhost devices are configured:
48 queues -> 8.71% [.] vhost_dev_sync_region.isra.13
2 devices, 8 queues -> 7.97% [.] vhost_dev_sync_region.isra.14

For some use-cases, it is helpful to have more than one UART
available to the guest. If the second UART slot is not already used
for a TrustZone Secure-World-only UART, create it as a NonSecure UART
only when the user provides a serial backend (e.g. via a second
-serial command line option).
This avoids problems where existing guest software only expects a
single UART, and gets confused by the second UART in the DTB. The
major example of this is older EDK2 firmware, which will send the
GRUB bootloader output to UART1 and the guest serial output to UART0.
Users who want to use both UARTs with a guest setup including EDK2
are advised to update to EDK2 release edk2-stable202311 or newer.
(The prebuilt EDK2 blobs QEMU upstream provides are new enough.)
The relevant EDK2 changes are the ones described here:

AST2700 dram size calculation is not back compatible AST2600.
According to the DDR capacity hardware behavior,
if users write the data to the address which is beyond the ram size,
it would write the data to the "address % ram_size".
For example:
a. sdram base address "0x4 00000000"
b. sdram size 1 GiB
The available address range is from "0x4 00000000" to "0x4 3FFFFFFF".
If users write 0x12345678 to address "0x5 00000000",
the value of DRAM address 0 (base address 0x4 00000000) will be 0x12345678.
Add aspeed_soc_ast2700_dram_init to calculate the dram size and add
memory I/O whose address range is from "max_ram_size - ram_size" to max_ram_size
and its read/write handler to emulate DDR capacity hardware behavior.

AST2700 interrupt controller(INTC) provides hardware interrupt interfaces
to interrupt of processors PSP, SSP and TSP. In INTC, each interrupt of
INT 128 to INT136 combines 32 interrupts.
Introduce a new aspeed_intc class with instance_init and realize handlers.
So far, this model only supports GICINT128 to GICINT136.
It creates 9 GICINT or-gates to connect 32 interrupts sources
from GICINT128 to GICINT136 as IRQ GPIO-OUTPUT pins.
Then, this model registers IRQ handler with its IRQ GPIO-INPUT pins which
connect to GICINT or-gates. And creates 9 GICINT IRQ GPIO-OUTPUT pins which
connect to GIC device with GIC IRQ 128 to 136.
If one interrupt source from GICINT128 to GICINT136
set irq, the OR-GATE irq callback function is called and set irq to INTC by
OR-GATE GPIO-OUTPUT pins. Then, the INTC irq callback function is called and
set irq to GIC by its GICINT IRQ GPIO-OUTPUT pins. Finally, the GIC irq
callback function is called and set irq to CPUs and
CPUs execute Interrupt Service Routine (ISR).

The Aspeed SMC device model use to have a 'sdram_base' property. It
was removed by commit d177892d4a ("aspeed/smc: Remove unused
"sdram-base" property") because previous changes simplified the DMA
transaction model to use an offset in RAM and not the physical
address.
The AST2700 SoC has larger address space (64-bit) and a new register
DMA DRAM Side Address High Part (0x7C) is introduced to deal with the
high bits of the DMA address. To be able to compute the offset of the
DMA transaction, as done on the other SoCs, we will need to know where
the DRAM is mapped in the address space. Re-introduce a "dram-base"
property to hold this value.

In SNP, the hashes page designated with a specific metadata entry
published in AmdSev OVMF.
Therefore, if the user enabled kernel hashes (for measured direct boot),
QEMU should prepare the content of hashes table, and during the
processing of the metadata entry it copy the content into the designated
page and encrypt it.
Note that in SNP (unlike SEV and SEV-ES) the measurements is done in
whole 4KB pages. Therefore QEMU zeros the whole page that includes the
hashes table, and fills in the kernel hashes area in that page, and then
encrypts the whole page. The rest of the page is reserved for SEV
launch secrets which are not usable anyway on SNP.
If the user disabled kernel hashes, QEMU pre-validates the kernel hashes
page as a zero page.

The TCGCPUOps::cpu_exec_halt method is called from cpu_handle_halt()
when the CPU is halted, so that a target CPU emulation can do
anything target-specific it needs to do. (At the moment we only use
this on i386.)
The current specification of the method doesn't allow the target
specific code to do something different if the CPU is about to come
out of the halt state, because cpu_handle_halt() only determines this
after the method has returned. (If the method called cpu_has_work()
itself this would introduce a potential race if an interrupt arrived
between the target's method implementation checking and
cpu_handle_halt() repeating the check.)
Change the definition of the method so that it returns a bool to
tell cpu_handle_halt() whether to stay in halt or not.
We will want this for the Arm target, where FEAT_WFxT wants to do
some work only for the case where the CPU is in halt but about to
leave it.

Commit dfcf74fa ("virtio-gpu: fix scanout migration post-load") broke
forward/backward version migration. Versioning of nested VMSD structures
is not straightforward, as the wire format doesn't have nested
structures versions. Introduce x-scanout-vmstate-version and a field
test to save/load appropriately according to the machine version.

Add module_id member in X86CPUTopoIDs.
module_id can be parsed from APIC ID, so also update APIC ID parsing
rule to support module level. With this support, the conversions with
module level between X86CPUTopoIDs, X86CPUTopoInfo and APIC ID are
completed.
module_id can be also generated from cpu topology, and before i386
supports "modules" in smp, the default "modules per die" (modules *
clusters) is only 1, thus the module_id generated in this way is 0,
so that it will not conflict with the module_id generated by APIC ID.

Support module level in i386 cpu topology structure "X86CPUTopoInfo".
Since x86 does not yet support the "modules" parameter in "-smp",
X86CPUTopoInfo.modules_per_die is currently always 1.
Therefore, the module level width in APIC ID, which can be calculated by
"apicid_bitwidth_for_count(topo_info->modules_per_die)", is always 0 for
now, so we can directly add APIC ID related helpers to support module
level parsing.
In addition, update topology structure in test-x86-topo.c.

Currently, QEMU checks the specify number of topology domains to detect
if there's extended topology levels (e.g., checking nr_dies).
With this bitmap, the extended CPU topology (the levels other than SMT,
core and package) could be easier to detect without touching the
topology details.
This is also in preparation for the follow-up to decouple CPUID[0x1F]
subleaf with specific topology level.

In the -bios case the "isa-bios" memory region is an alias to the BIOS mapped
to the top of the 4G memory boundary. Do the same in the -pflash case, but only
for new machine versions for migration compatibility. This establishes common
behavior and makes pflash commands work in the "isa-bios" region which some
real-world legacy bioses rely on.
Note that in the sev_enabled() case, the "isa-bios" memory region in the -pflash
case will now also point to encrypted memory, just like it already does in the
-bios case.

This commit introduces utility functions for the creation and deallocation
of QemuDmaBuf instances. Additionally, it updates all relevant sections
of the codebase to utilize these new utility functions.
v7: remove prefix, "dpy_gl_" from all helpers
qemu_dmabuf_free() returns without doing anything if input is null
(Daniel P. Berrangé <berrange@redhat.com>)
call G_DEFINE_AUTOPTR_CLEANUP_FUNC for qemu_dmabuf_free()
(Daniel P. Berrangé <berrange@redhat.com>)
v8: Introduction of helpers was removed as those were already added
by the previous commit
v9: set dmabuf->allow_fences to 'true' when dmabuf is created in
virtio_gpu_create_dmabuf()/virtio-gpu-udmabuf.c
removed unnecessary spaces were accidently added in the patch,
'ui/console: Use qemu_dmabuf_new() a...'
v11: Calling qemu_dmabuf_close was removed as closing dmabuf->fd will be
done in qemu_dmabuf_free anyway.
(Daniel P. Berrangé <berrange@redhat.com>)
v12: --- Calling qemu_dmabuf_close separately as qemu_dmabuf_free doesn't
do it.
--- 'dmabuf' is now allocated space so it should be freed at the end of
dbus_scanout_texture
v13: --- Immediately free dmabuf after it is released to prevent possible
leaking of the ptr
(Marc-André Lureau <marcandre.lureau@redhat.com>)
--- Use g_autoptr macro to define *dmabuf for auto clean up instead of
calling qemu_dmabuf_free
(Marc-André Lureau <marcandre.lureau@redhat.com>)
v14: --- (vhost-user-gpu) Change qemu_dmabuf_free back to g_clear_pointer
as it was done because of some misunderstanding (v13).
--- (vhost-user-gpu) g->dmabuf[m->scanout_id] needs to be set to NULL
to prevent freed dmabuf to be accessed again in case if(fd==-1)break;
happens (before new dmabuf is allocated). Otherwise, it would cause
invalid memory access when the same function is executed. Also NULL
check should be done before qemu_dmabuf_close (it asserts dmabuf!=NULL.).

The rtc-reset-reinjection QMP command is specific to x86, other boards do not
have the ACK tracking functionality that is needed for RTC interrupt
reinjection. Therefore the QMP command is only included in x86, but
qmp_rtc_reset_reinjection() is implemented by hw/rtc/mc146818rtc.c
and requires tracking of all created RTC devices. Move the implementation
to hw/i386, so that 1) it is available even if no RTC device exist
2) the only RTC that exists is easily found in x86ms->rtc.

It is okay to register legacy backends in the middle of xen_bus_init().
All that the registration does is record the existence of the backend
in xenstore.
This makes it possible to remove them from the build without introducing
undefined symbols in xen_be_init(). It also removes the need for the
backend_register callback, whose only purpose is to avoid registering
nonfunctional backends.

Currently the sbsa_gdwt watchdog device hardcodes its frequency at
62.5MHz. In real hardware, this watchdog is supposed to be driven
from the system counter, which also drives the CPU generic timers.
Newer CPU types (in particular from Armv8.6) should have a CPU
generic timer frequency of 1GHz, so we can't leave the watchdog
on the old QEMU default of 62.5GHz.
Make the frequency a QOM property so it can be set by the board,
and have our only board that uses this device set that frequency
to the same value it sets the CPU frequency.

In x86, module is the topology level above core, which contains a set
of cores that share certain resources (in current products, the resource
usually includes L2 cache, as well as module scoped features and MSRs).
Though smp.clusters could also share the L2 cache resource [1], there
are following reasons that drive us to introduce the new smp.modules:
* As the CPU topology abstraction in device tree [2], cluster supports
nesting (though currently QEMU hasn't support that). In contrast,
(x86) module does not support nesting.
* Due to nesting, there is great flexibility in sharing resources
on cluster, rather than narrowing cluster down to sharing L2 (and
L3 tags) as the lowest topology level that contains cores.
* Flexible nesting of cluster allows it to correspond to any level
between the x86 package and core.
* In Linux kernel, x86's cluster only represents the L2 cache domain
but QEMU's smp.clusters is the CPU topology level. Linux kernel will
also expose module level topology information in sysfs for x86. To
avoid cluster ambiguity and keep a consistent CPU topology naming
style with the Linux kernel, we introduce module level for x86.
The module is, in existing hardware practice, the lowest layer that
contains the core, while the cluster is able to have a higher
topological scope than the module due to its nesting.
Therefore, place the module between the cluster and the core:
drawer/book/socket/die/cluster/module/core/thread
With the above topological hierarchy order, introduce module level
support in MachineState and MachineClass.

Besides, since commit 6a0057aa22 ("docs/devel: make a statement

If you do use template header files they should be named with

[PMM: update to new reset hold method signature;
fixed a few checkpatch nits]
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Some devices and machines need to handle the reset before a vmsave
snapshot is loaded differently -- the main user is the handling of
RNG seed information, which does not want to put a new RNG seed into
a ROM blob when we are doing a snapshot load.
Currently this kind of reset handling is supported only for:
* TYPE_MACHINE reset methods, which take a ShutdownCause argument
* reset functions registered with qemu_register_reset_nosnapshotload
To allow a three-phase-reset device to also distinguish "snapshot
load" reset from the normal kind, add a new ResetType
RESET_TYPE_SNAPSHOT_LOAD. All our existing reset methods ignore
the reset type, so we don't need to update any device code.
Add the enum type, and make qemu_devices_reset() use the
right reset type for the ShutdownCause it is passed. This
allows us to get rid of the device_reset_reason global we
were using to implement qemu_register_reset_nosnapshotload().

We pass a ResetType argument to the Resettable class enter
phase method, but we don't pass it to hold and exit, even though
the callsites have it readily available. This means that if
a device cared about the ResetType it would need to record it
in the enter phase method to use later on. Pass the type to
all three of the phase methods to avoid having to do that.

When introduce NMI interrupt, there are some updates to the semantics for the
register ICC_IAR1_EL1 and ICC_HPPIR1_EL1. For ICC_IAR1_EL1 register, it
should return 1022 if the intid has non-maskable property. And for
ICC_NMIAR1_EL1 register, it should return 1023 if the intid do not have
non-maskable property. Howerever, these are not necessary for ICC_HPPIR1_EL1
register.
And the APR and RPR has NMI bits which should be handled correctly.

The current handling of invalid virtqueue elements inside the TX/RX virt
queue handlers is wrong.
They are added in a per-stream invalid queue to be processed after the
handler is done examining each message, but the invalid message might
not be specifying any stream_id; which means it's invalid to add it to
any stream->invalid queue since stream could be NULL at this point.
This commit moves the invalid queue to the VirtIOSound struct which
guarantees there will always be a valid temporary place to store them
inside the tx/rx handlers. The queue will be emptied before the handler
returns, so the queue must be empty at any other point of the device's
lifetime.

aspeed/smc: Only wire flash devices at reset
ppc/pnv: I2C controller is not user creatable
vfio/iommufd: Fix memory leak
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
The Aspeed machines have many Static Memory Controllers (SMC), up to
8, which can only drive flash memory devices. Commit 27a2c66c92
("aspeed/smc: Wire CS lines at reset") tried to ease the definitions
of these devices by allowing flash devices from the command line to be
attached to a SSI bus. For that, the wiring of the CS lines of the
Aspeed SMC controller was moved at reset. Two assumptions are made
though, first that the device has a SSI_GPIO_CS GPIO line, which is
not always the case, and second that it is a flash device.
Correct this problem by ensuring that the devices attached to the bus
are of the correct flash type. This fixes a QEMU abort when devices
without a CS line, such as the max111x, are passed on the command
line.
While at it, export TYPE_M25P80 used in the Xilinx Versal Virtual
machine.

legacy mode doesn't support structures of type 2 and more,
and CLI has a check for '-smbios type' option, however it's
still possible to sneak in type4 as a blob with '-smbios file'
option. However doing the later makes SMBIOS tables broken
since SeaBIOS doesn't expect that.
Rather than trying to add support for type4 to legacy code
(both QEMU and SeaBIOS), simplify smbios_get_table_legacy()
by dropping not relevant check in legacy code and error out

ACPI spec provides a scheme to associate "Generic Initiators" [1]
(e.g. heterogeneous processors and accelerators, GPUs, and I/O devices with
integrated compute or DMA engines GPUs) with Proximity Domains. This is
achieved using Generic Initiator Affinity Structure in SRAT. During bootup,
Linux kernel parse the ACPI SRAT to determine the PXM ids and create a NUMA
node for each unique PXM ID encountered. Qemu currently do not implement
these structures while building SRAT.
Add GI structures while building VM ACPI SRAT. The association between
device and node are stored using acpi-generic-initiator object. Lookup
presence of all such objects and use them to build these structures.
The structure needs a PCI device handle [2] that consists of the device BDF.
The vfio-pci device corresponding to the acpi-generic-initiator object is
located to determine the BDF.

NVIDIA GPU's support MIG (Mult-Instance GPUs) feature [1], which allows
partitioning of the GPU device resources (including device memory) into
several (upto 8) isolated instances. Each of the partitioned memory needs
a dedicated NUMA node to operate. The partitions are not fixed and they
can be created/deleted at runtime.
Unfortunately Linux OS does not provide a means to dynamically create/destroy
NUMA nodes and such feature implementation is not expected to be trivial. The
nodes that OS discovers at the boot time while parsing SRAT remains fixed. So
we utilize the Generic Initiator (GI) Affinity structures that allows
association between nodes and devices. Multiple GI structures per BDF is
possible, allowing creation of multiple nodes by exposing unique PXM in each
of these structures.
Implement the mechanism to build the GI affinity structures as Qemu currently
does not. Introduce a new acpi-generic-initiator object to allow host admin
link a device with an associated NUMA node. Qemu maintains this association
and use this object to build the requisite GI Affinity Structure.
When multiple NUMA nodes are associated with a device, it is required to
create those many number of acpi-generic-initiator objects, each representing
a unique device:node association.
Following is one of a decoded GI affinity structure in VM ACPI SRAT.

An admin can provide a range of acpi-generic-initiator objects, each
associating a device (by providing the id through pci-dev argument)
to the desired NUMA node (using the node argument). Currently, only PCI
device is supported.
For the grace hopper system, create a range of 8 nodes and associate that
with the device using the acpi-generic-initiator object. While a configuration
of less than 8 nodes per device is allowed, such configuration will prevent
utilization of the feature to the fullest. The following sample creates 8
nodes per PCI device for a VM with 2 PCI devices and link them to the
respecitve PCI device using acpi-generic-initiator objects:
-numa node,nodeid=2 -numa node,nodeid=3 -numa node,nodeid=4 \

- H_GUEST_GET_STATE which is used to get state of a nested guest or
a guest VCPU. The value field for each element in the request is
destination to be updated to reflect current state on success.
- H_GUEST_SET_STATE which is used to modify the state of a guest or
a guest VCPU. On success, guest (or its VCPU) state shall be
updated as per the value field for the requested element(s).

Nested PAPR API provides a standard Guest State Buffer (GSB) format
with unique IDs for each guest state element for which get/set state is
supported by the API. Some of the elements are read-only and/or guest-wide.
Introducing additional required GSB elements and helper routines for state
exchange of each of the nested guest state elements for which get/set state
should be supported by the API.

The current post-loading code for scanout has a FIXME: it doesn't take
the resource region/rect into account. But there is more, when adding
blob migration support in commit f66767f75c, I didn't realize that blob
resources could be used for scanouts. This situationn leads to a crash
during post-load, as they don't have an associated res->image.
virtio_gpu_do_set_scanout() handle all cases, but requires the
associated virtio_gpu_framebuffer, which is currently not saved during
migration.
Add a v2 of "virtio-gpu-one-scanout" with the framebuffer fields, so we
can restore blob scanouts, as well as fixing the existing FIXME.

When setting GLIB_VERSION_MAX_ALLOWED to GLIB_VERSION_2_58 or higher,
glib adds type safety checks to the g_steal_pointer() macro. This
triggers errors in the ct3_build_cdat_entries_for_mr() function which
uses the g_steal_pointer() for type-casting from one pointer type to
the other (which also looks quite weird since the local pointers have
all been declared with g_autofree though they are never freed here).
Fix it by using a proper typecast instead. For making this possible, we
have to remove the QEMU_PACKED attribute from some structs since GCC
otherwise complains that the source and destination pointer might
have different alignment restrictions. Removing the QEMU_PACKED should
be fine here since the structs are already naturally aligned. Anyway,
add some QEMU_BUILD_BUG_ON() statements to make sure that we've got
the right sizes (without padding in the structs).

Hyper-V Dynamic Memory and VMBus misc small patches
This pull request contains two small patches to hv-balloon:
the first one replacing alloca() usage with g_malloc0() + g_autofree
and the second one adding additional declaration of a protocol message
struct with an optional field explicitly defined to avoid a Coverity
warning.
Also included is a VMBus patch to print a warning when it is enabled
without the recommended set of Hyper-V features (enlightenments) since
some Windows versions crash at boot in this case.

Allow cpr-reboot for vfio if the guest is in the suspended runstate. The
guest drivers' suspend methods flush outstanding requests and re-initialize
the devices, and thus there is no device state to save and restore. The
user is responsible for suspending the guest before initiating cpr, such as
by issuing guest-suspend-ram to the qemu guest agent.
Relax the vfio blocker so it does not apply to cpr, and add a notifier that
verifies the guest is suspended.

Some Windows versions crash at boot or fail to enable the VMBus device if
they don't see the expected set of Hyper-V features (enlightenments).
Since this provides poor user experience let's warn user if the VMBus
device is enabled without the recommended set of Hyper-V features.
The recommended set is the minimum set of Hyper-V features required to make
the VMBus device work properly in Windows Server versions 2016, 2019 and
2022.

Since the presence of a hot add memory region is optional in hot add
request message it wasn't part of this message declaration
(struct dm_hot_add).
Instead, the code allocated such enlarged message by simply adding the
necessary size for this extra field to the size of basic hot add message
struct.
However, Coverity considers accessing this extra member to be
an out-of-bounds access, even thought the memory is actually there.
Fix this by adding an extended variant of this message that explicitly has
an additional union dm_mem_page_range at its end.

Features supported :
- the 8 STM32L4x5 GPIOs are initialized with their reset values
(except IDR, see below)
- input mode : setting a pin in input mode "externally" (using input
irqs) results in an out irq (transmitted to SYSCFG)
- output mode : setting a bit in ODR sets the corresponding out irq
(if this line is configured in output mode)
- pull-up, pull-down
- push-pull, open-drain
Difference with the real GPIOs :
- Alternate Function and Analog mode aren't implemented :
pins in AF/Analog behave like pins in input mode
- floating pins stay at their last value
- register IDR reset values differ from the real one :
values are coherent with the other registers reset values
and the fact that AF/Analog modes aren't implemented
- setting I/O output speed isn't supported
- locking port bits isn't supported
- ADC function isn't supported
- GPIOH has 16 pins instead of 2 pins
- writing to registers LCKR, AFRL, AFRH and ASCR is ineffective

The UEFI loading mode in loongarch is very different
from that in other architectures:loongarch's UEFI code
is in rom, while other architectures' UEFI code is in flash.
loongarch UEFI can be loaded as follows:
-machine virt,pflash=pflash0-format
-bios ./QEMU_EFI.fd
Other architectures load UEFI using the following methods:
-machine virt,pflash0=pflash0-format,pflash1=pflash1-format
loongarch's UEFI loading method makes qemu and libvirt incompatible
when using NVRAM, and the cost of loongarch's current loading method
far outweighs the benefits, so we decided to use the same UEFI loading
scheme as other architectures.

Implement a ResetContainer. This is a subclass of Object, and it
implements the Resettable interface. The container holds a list of
arbitrary other objects which implement Resettable, and when the
container is reset, all the objects it contains are also reset.
This will allow us to have a 3-phase-reset equivalent of the old
qemu_register_reset() API: we will have a single "simulation reset"
top level ResetContainer, and objects in it are the equivalent of the
old QEMUResetHandler functions.
The qemu_register_reset() API manages its list of callbacks using a
QTAILQ, but here we use a GPtrArray for our list of Resettable
children: we expect the "remove" operation (which will need to do an
iteration through the list) to be fairly uncommon, and we get simpler
code with fewer memory allocations.
Since there is currently no listed owner in MAINTAINERS for the
existing reset-related source files, create a new section for
them, and add these new files there also.

In the previous design of ASPEED SOCs QEMU model, it set the boot
address at "0" which was the hardcode setting for ast10x0, ast2600,
ast2500 and ast2400.
According to the design of ast2700, it has a bootmcu(riscv-32) which
is used for executing SPL and initialize DRAM and copy u-boot image
from SPI/Flash to DRAM at address 0x400000000 at SPL boot stage.
Then, CPUs(cortex-a35) execute u-boot, kernel and rofs.
Currently, qemu not support emulate two CPU architectures
at the same machine. Therefore, qemu will only support
to emulate CPU(cortex-a35) side for ast2700 and the boot
address is "0x4 00000000".
Fixed hardcode boot address "0" for future models using
a different mapping address.

One of the functions of the ChipTOD is to transfer TOD to the Core
(aka PC - Pervasive Core) timebase facility.
The ChipTOD can be programmed with a target address to send the TOD
value to. The hardware implementation seems to perform this by
sending the TOD value to a SCOM address.
This implementation grabs the core directly and manipulates the
timebase facility state in the core. This is a hack, but it works
enough for now. A better implementation would implement the transfer
to the PnvCore xscom register and drive the timebase state machine
from there.

The ChipTOD (for Time-Of-Day) is a chip pervasive facility in IBM POWER
(powernv) processors that keeps a time of day clock.
In particular for this model are facilities that initialise and start
the time of day clock, and that synchronise that clock to cores on the
chip, and to other chips. In this way, all cores on all chips can
synchronise timebase (TB).
This model implements functionality sufficient to run the skiboot
chiptod synchronisation procedure (with the following core timebase
state machine implementation). It does not modify the TB in the cores
where the real hardware would, because the QEMU ppc timebase
implementation is always synchronised acros all cores.

A POWER10 chip is divided into logical units called chiplets. Chiplets
are broadly divided into "core chiplets" (with the processor cores) and
"nest chiplets" (with everything else). Each chiplet has an attachment
to the pervasive bus (PIB) and with chiplet-specific registers. All nest
chiplets have a common basic set of registers and This model will provide
the registers functionality for common registers of nest chiplet (Pervasive
Chiplet, PB Chiplet, PCI Chiplets, MC Chiplet, PAU Chiplets)

Allow external devices to drive pca9552 input pins by adding
input GPIO's to the model. This allows a device to connect
its output GPIO's to the pca9552 input GPIO's.
In order for an external device to set the state of a pca9552
pin, the pin must first be configured for high impedance (LED
is off). If the pca9552 pin is configured to drive the pin low
(LED is on), then external input will be ignored.
Here is a table describing the logical state of a pca9552 pin
given the state being driven by the pca9552 and an external device:

and thus exposed to a lot of files that are not part of the IDE subsystem.
Stop including internal.h there and use the appropriate new headers
ide-bus.h and ide-dma.h instead.

The MPS2 SCC device is broadly the same for all FPGA images, but has
minor differences in the behaviour of the CFG registers depending on
the image. In many cases we don't really care about the functionality
controlled by these registers and a reads-as-written or similar
behaviour is sufficient for the moment.
For the AN536 the required behaviour is:
* A_CFG0 has CPU reset and halt bits
- implement as reads-as-written for the moment
* A_CFG1 has flash or ATCM address 0 remap handling
- QEMU doesn't model this; implement as reads-as-written
* A_CFG2 has QSPI select (like AN524)
- implemented (no behaviour, as with AN524)
* A_CFG3 is MCC_MSB_ADDR "additional MCC addressing bits"
- QEMU doesn't care about these, so use the existing
RAZ behaviour for convenience
* A_CFG4 is board rev (like all other images)
- no change needed
* A_CFG5 is ACLK frq in hz (like AN524)
- implemented as reads-as-written, as for other boards
* A_CFG6 is core 0 vector table base address
- implemented as reads-as-written for the moment
* A_CFG7 is core 1 vector table base address
- implemented as reads-as-written for the moment
Make the changes necessary for this; leave TODO comments where
appropriate to indicate where we might want to come back and
implement things like CPU reset.
The other aspects of the device specific to this FPGA image (like the
values of the board ID and similar registers) will be set via the
device's qdev properties.

Armv8.1+ CPUs have the Virtual Host Extension (VHE) which adds a
non-secure EL2 virtual timer. We implemented the timer itself in the
CPU model, but never wired up its IRQ line to the GIC.
Wire up the IRQ line (this is always safe whether the CPU has the
interrupt or not, since it always creates the outbound IRQ line).
Report it to the guest via dtb and ACPI if the CPU has the feature.
The DTB binding is documented in the kernel's
Documentation/devicetree/bindings/timer/arm\,arch_timer.yaml
and the ACPI table entries are documented in the ACPI specification
version 6.3 or later.
Because the IRQ line ACPI binding is new in 6.3, we need to bump the
FADT table rev to show that we might be using 6.3 features.
Note that exposing this IRQ in the DTB will trigger a bug in EDK2
versions prior to edk2-stable202311, for users who use the virt board
with 'virtualization=on' to enable EL2 emulation and are booting an
EDK2 guest BIOS, if that EDK2 has assertions enabled. The effect is
that EDK2 will assert on bootup:
ASSERT [ArmTimerDxe] /home/kraxel/projects/qemu/roms/edk2/ArmVirtPkg/Library/ArmVirtTimerFdtClientLib/ArmVirtTimerFdtClientLib.c(72): PropSize == 36 || PropSize == 48
If you see that assertion you should do one of:
* update your EDK2 binaries to edk2-stable202311 or newer
* use the 'virt-8.2' versioned machine type
* not use 'virtualization=on'
(The versions shipped with QEMU itself have the fix.)

When destroying/unrefing resources, devices such as virtio-gpu-rutabaga
need to do their own bookkeeping (free rutabaga resources that are
associated with the virtio_gpu_simple_resource).
This commit adds a class method so that virtio-gpu-rutabaga can override
it in the next commit.

Previously not all references mentioned any spec version at all.
Given r3.1 is the current specification available for evaluation at
www.computeexpresslink.org update references to refer to that.
Hopefully this won't become a never ending job.
A few structure definitions have been updated to add new fields.
Defaults of 0 and read only are valid choices for these new DVSEC
registers so go with that for now.
There are additional error codes and some of the 'questions' in
the comments are resolved now.
Update documentation reference to point to the CXL r3.1 specification
with naming closer to what is on the cover.
For cases where there are structure version numbers, add defines
so they can be found next to the register definitions.

In the current mdev_reg_read() implementation, it consistently returns
that the Media Status is Ready (01b). This was fine until commit
25a52959f9 ("hw/cxl: Add support for device sanitation") because the
media was presumed to be ready.
However, as per the CXL 3.0 spec "8.2.9.8.5.1 Sanitize (Opcode 4400h)",
during sanitation, the Media State should be set to Disabled (11b). The
mentioned commit correctly sets it to Disabled, but mdev_reg_read()
still returns Media Status as Ready.
To address this, update mdev_reg_read() to read register values instead
of returning dummy values.
Note that __toggle_media() managed to not only write something
that no one read, it did it to the wrong register storage and
so changed the reported mailbox size which was definitely not
the intent. That gets fixed as a side effect of allocating
separate state storage for this register.

QEMU populates the apic_state attribute of x86 CPUs if supported by real
hardware or if SMP is active. When handling interrupts, it just checks whether
apic_state is populated to route the interrupt to the PIC or to the APIC.
However, chapter 10.4.3 of [1] requires that:
When IA32_APIC_BASE[11] is 0, the processor is functionally equivalent to an
IA-32 processor without an on-chip APIC.
This means that when apic_state is populated, QEMU needs to check for the
MSR_IA32_APICBASE_ENABLE flag in addition. Implement this which fixes some
real-world BIOSes.

Currently the DRQ IRQ is updated every time DMA data is sent/received which
is both inefficient and causes excessive logging of the DRQ state. Add a
new drq_state bool that only updates the DRQ IRQ if its state changes.
This commit adds the new drq_state bool to the migration state: since the
version number has already been increased earlier in the series, there is
no need to repeat it again here. The DRQ IRQ is (currently) only used for
PDMA transfers which already have a migration break in this series so
there are no problems setting its value post-load.

According to the datasheet the previous ESP command remains in the ESP_CMD
register, which caused a problem when consecutive TI commands were issued as
it becomes impossible for the state machine to know when the first TI
command finishes.
This was the original reason for introducing the ti_cmd field which kept
track of the last written command for this purpose. However closer reading
of the datasheet shows that a TI command that terminates due to a change of
SCSI target phase resets the ESP_CMD register to zero which solves this
problem.
Now that this has been fixed in the previous commit, remove the unneeded
ti_cmd field and access the ESP_CMD register directly instead. Bump the
vmstate_esp version to indicate that the ti_cmd field is no longer included.

The Astro/Elroy chip can work in either Hard-Fail or Soft-Fail mode.
Hard fail means the system bus will send an HPMC (=crash) to the
processor, soft fail means the system bus will ignore timeouts of
MMIO-reads or MMIO-writes and return -1ULL.
The HF mode is controlled by a bit in the status register and is usually
programmed by the OS. Return the corresponing values based on the current
value of that bit.

usb-storage is for the most part just a wrapper around an internally
created scsi-disk device. It uses DEFINE_BLOCK_PROPERTIES() to offer all
of the usual block device properties to the user, but then only forwards
a few select properties to the internal device while the rest is
silently ignored.
This changes scsi_bus_legacy_add_drive() to accept a whole BlockConf
instead of some individual values inside of it so that usb-storage can
now pass the whole configuration to the internal scsi-disk. This enables
the remaining block device properties, e.g. logical/physical_block_size
or discard_granularity.

The VirtIOBlock::rq field has had the type void * since its introduction
in commit 869a5c6df1 ("Stop VM on error in virtio-blk. (Gleb
Natapov)").
Perhaps this was done to avoid the forward declaration of
VirtIOBlockReq.
Hanna Czenczek <hreitz@redhat.com> pointed out the missing type. Specify
the actual type because there is no need to use void * here.

QEMU initializes preallocated backend memory as the objects are parsed from
the command line. This is not optimal in some cases (e.g. memory spanning
multiple NUMA nodes) because the memory objects are initialized in series.
Allow the initialization to occur in parallel (asynchronously). In order to
ensure optimal thread placement, asynchronous initialization requires prealloc
context threads to be in use.
