965bc08310 qdev: Add a granule_mode property
Introduce a new enum type property allowing to set an
IOMMU granule. Values are 4k, 8k, 16k, 64k and host.
This latter indicates the vIOMMU granule will match
the host page size.

A subsequent patch will add such a property to the
virtio-iommu device.

f28b958cbf hw/xen: Extract 'xen_igd.h' from 'xen_pt.h'
"hw/xen/xen_pt.h" requires "hw/xen/xen_native.h" which is target
specific. It also declares IGD methods, which are not target

Target-agnostic code can use IGD methods. To allow that, extract
these methos into a new "hw/xen/xen_igd.h" header.

00691b1f6a hw/mem/cxl_type3: Fix problem with g_steal_pointer()
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).

256f016658 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.

0cb51c183a vfio: allow cpr-reboot migration if suspended
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.

6093637b4d vmbus: Print a warning when enabled without the recommended set of features
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.

546987284a hv-balloon: define dm_hot_add_with_region to avoid Coverity warning
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.

The sun4v RTC device model added under commit a0e893039c in 2016

not compatible with other QEMU code which has a GPL-v2-only license.

Relicense the code in the .c and the .h file to GPL-v2-or-later,
to make it compatible with the rest of QEMU.

1cdcfb6e93 hw/gpio: Implement STM32L4x5 GPIO
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

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.

c006147122 plugins: create CPUPluginState and migrate plugin_mask
As we expand the per-vCPU data for plugins we don't want to pollute
CPUState. For now this just moves the plugin_mask (renamed to
event_mask) as the memory callbacks are accessed directly by TCG
generated code.

cda5a7d640 hw/misc/bcm2835_property: Add missed BCM2835 properties
Our model of the bcm2835 mailbox is missing a few properties
that we need for the raspi4 kernel:
 * RPI_FWREQ_GET_CLOCKS
 * RPI_FWREQ_GET_THROTTLED
 * RPI_FWREQ_VCHIQ_INIT

Add minimal implementations of them.

4c046ce37a hw/core: Add ResetContainer which holds objects implementing Resettable
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.

db052d0eaf aspeed: fix hardcode boot address 0
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.

cde2ba34a9 ppc/pnv: Implement the ChipTOD to Core transfer
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.

9a69950feb ppc/pnv: Add POWER9/10 chiptod model
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.

input GPIO's to the model.  This allows a device to connect

In order for an external device to set the state of a pca9552

2df5c1f5b0 ppc/spapr: Introduce SPAPR_IRQ_NR_IPIS to refer IRQ range for CPU IPIs.
spapr_irq_init currently uses existing macro SPAPR_XIRQ_BASE to refer to
the range of CPU IPIs during initialization of nr-irqs property.
It is more appropriate to have its own define which can be further
reused as appropriate for correct interpretation.

a3d0cf82df hw/ppc/spapr_hcall: Rename {softmmu -> vhyp_mmu}_resize_hpt_pr
Since 'softmmu' is quite a loaded term in QEMU, rename the vhyp MMU
facilities to use the vhyp_mmu_ prefix rather than softmmu_.

vhyp_mmu_ is chosen because the code that manipulates the hash table
via guest software hypercalls is QEMU's implementation of the PAPR
hypervisor interface, called vhyp.

6f6ad2b245 hw/i386/pc: Confine system flash handling to pc_sysfw
Rather than distributing PC system flash handling across three files, let's
confine it to one. Now, pc_system_firmware_init() creates, configures and cleans
up the system flash which makes the code easier to understand. It also avoids
the extra call to pc_system_flash_cleanup_unused() in the Xen case.

726c609936 usb: inline device creation functions
Allow boards to use the device creation functions even if USB itself
is not available; of course the functions will fail inexorably, but
this can be okay if the calls are conditional on the existence of
some USB host controller device.  This is for example the case for
hw/mips/loongson3_virt.c.

2a1019f209 i386/pc: Drop pc_machine_kvm_type()
pc_machine_kvm_type() was introduced by commit e21be724ea ("i386/xen:
add pc_machine_kvm_type to initialize XEN_EMULATE mode") to do Xen
specific initialization by utilizing kvm_type method.

commit eeedfe6c63 ("hw/xen: Simplify emulated Xen platform init")
moves the Xen specific initialization to pc_basic_device_init().

There is no need to keep the PC specific kvm_type() implementation
anymore. So we'll fallback to kvm_arch_get_default_type(), which
simply returns 0.

2a5ee4e18d hw/misc/mps2-scc: Make changes needed for AN536 FPGA image
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.

1ec896fe7c hw/arm/virt: Wire up non-secure EL2 virtual timer IRQ
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.)

330399bd89 virtio-gpu.c: add resource_destroy class method
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.

8700ee15de hw/cxl: Standardize all references on CXL r3.1 and minor updates
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.

f7509f462c hw/cxl/device: read from register values in mdev_reg_read()
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.

c2e6d7d8e7 hw/i386/x86: Fix PIC interrupt handling if APIC is globally disabled
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.

This patch derives vhost-user-input from vhost-user-base class, so make
the input stub as a simpler boilerplate wrapper.

With the refactoring, vhost-user-input adds the property 'chardev', this
leads to conflict with the vhost-user-input-pci adds the same property.
To resolve the error, remove the duplicate property from
vhost-user-input-pci.

442de89a93 esp.c: keep track of the DRQ state during DMA
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.

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.

f410b688af hw/pci-host/astro: Implement Hard Fail and Soft Fail mode
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.

This regressed qemu-system-xtensa:

    TEST    test_load_store on xtensa
  qemu-system-xtensa: Some ROM regions are overlapping
  These ROM regions might have been loaded by direct user request or by default.
  They could be BIOS/firmware images, a guest kernel, initrd or some other file loaded into guest memory.
  Check whether you intended to load all this guest code, and whether it has been built to load to the correct addresses.

  The following two regions overlap (in the memory address space):
    test_load_store ELF program header segment 1 (addresses 0x0000000000001000 - 0x0000000000001f26)

3089637461 scsi: Don't ignore most usb-storage properties
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.

8802f4f4e3 virtio-blk: declare VirtIOBlock::rq with a type
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.

04accf43df oslib-posix: initialize backend memory objects in parallel
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.

2a98878ff4 hw/net/lasi_i82596: use qemu_create_nic_device()
Create the device only if there is a corresponding NIC config for it.
Remove the explicit check on nd_table[0].used from hw/hppa/machine.c
which (since commit d8a3220005) tries to do the same thing.

The lasi_82596 support has been disabled since it was first introduced,
since enable_lasi_lan() has always been zero. This allows the user to
enable it by explicitly requesting a NIC model 'lasi_82596' or just
using the alias 'lasi'. Otherwise, it defaults to a PCI NIC as before.

7d6eff13b3 hw/xen: use qemu_create_nic_bus_devices() to instantiate Xen NICs
When instantiating XenBus itself, for each NIC which is configured with
either the model unspecified, or set to to "xen" or "xen-net-device",
create a corresponding xen-net-device for it.

Now we can revert the previous more hackish version which relied on the
platform code explicitly registering the NICs on its own XenBus, having
returned the BusState* from xen_bus_init() itself.

This also fixes the setup for Xen PV guests, which was previously broken
in various ways and never actually managed to peer with the netdev.

3fd941f3f1 hw/arm: Hook up FSI module in AST2600
This patchset introduces IBM's Flexible Service Interface(FSI).

Time for some fun with inter-processor buses. FSI allows a service
processor access to the internal buses of a host POWER processor to
perform configuration or debugging.

FSI has long existed in POWER processes and so comes with some baggage,
including how it has been integrated into the ASPEED SoC.

Working backwards from the POWER processor, the fundamental pieces of
interest for the implementation are:

1. The Common FRU Access Macro (CFAM), an address space containing
   various "engines" that drive accesses on buses internal and external
   to the POWER chip. Examples include the SBEFIFO and I2C masters. The
   engines hang off of an internal Local Bus (LBUS) which is described
   by the CFAM configuration block.

2. The FSI slave: The slave is the terminal point of the FSI bus for
   FSI symbols addressed to it. Slaves can be cascaded off of one
   another. The slave's configuration registers appear in address space
   of the CFAM to which it is attached.

3. The FSI master: A controller in the platform service processor (e.g.
   BMC) driving CFAM engine accesses into the POWER chip. At the
   hardware level FSI is a bit-based protocol supporting synchronous and
   DMA-driven accesses of engines in a CFAM.

4. The On-Chip Peripheral Bus (OPB): A low-speed bus typically found in
   POWER processors. This now makes an appearance in the ASPEED SoC due
   to tight integration of the FSI master IP with the OPB, mainly the
   existence of an MMIO-mapping of the CFAM address straight onto a
   sub-region of the OPB address space.

5. An APB-to-OPB bridge enabling access to the OPB from the ARM core in
   the AST2600. Hardware limitations prevent the OPB from being directly
   mapped into APB, so all accesses are indirect through the bridge.

The implementation appears as following in the qemu device tree:

    (qemu) info qtree
    bus: main-system-bus
      type System
      ...
      dev: aspeed.apb2opb, id ""
        gpio-out "sysbus-irq" 1
        mmio 000000001e79b000/0000000000001000
        bus: opb.1
          type opb
          dev: fsi.master, id ""
            bus: fsi.bus.1
              type fsi.bus
              dev: cfam.config, id ""
              dev: cfam, id ""
                bus: fsi.lbus.1
                  type lbus
                  dev: scratchpad, id ""
                    address = 0 (0x0)
        bus: opb.0
          type opb
          dev: fsi.master, id ""
            bus: fsi.bus.0
              type fsi.bus
              dev: cfam.config, id ""
              dev: cfam, id ""
                bus: fsi.lbus.0
                  type lbus
                  dev: scratchpad, id ""
                    address = 0 (0x0)

The LBUS is modelled to maintain the qdev bus hierarchy and to take
advantage of the object model to automatically generate the CFAM
configuration block. The configuration block presents engines in the
order they are attached to the CFAM's LBUS. Engine implementations
should subclass the LBusDevice and set the 'config' member of
LBusDeviceClass to match the engine's type.

CFAM designs offer a lot of flexibility, for instance it is possible for
a CFAM to be simultaneously driven from multiple FSI links. The modeling
is not so complete; it's assumed that each CFAM is attached to a single
FSI slave (as a consequence the CFAM subclasses the FSI slave).

As for FSI, its symbols and wire-protocol are not modelled at all. This
is not necessary to get FSI off the ground thanks to the mapping of the
CFAM address space onto the OPB address space - the models follow this
directly and map the CFAM memory region into the OPB's memory region.
Future work includes supporting more advanced accesses that drive the
FSI master directly rather than indirectly via the CFAM mapping, which
will require implementing the FSI state machine and methods for each of
the FSI symbols on the slave. Further down the track we can also look at
supporting the bitbanged SoftFSI drivers in Linux by extending the FSI
slave model to resolve sequences of GPIO IRQs into FSI symbols, and
calling the associated symbol method on the slave to map the access onto
the CFAM.

Testing:
    Tested by reading cfam config address 0 on rainier machine type.

ca782334cb hw/fsi: Introduce IBM's scratchpad device
This is a part of patchset where IBM's Flexible Service Interface is
introduced.

The scratchpad provides a set of non-functional registers. The firmware
is free to use them, hardware does not support any special management
support. The scratchpad registers can be read or written from LBUS
slave. The scratch pad is managed under FSI CFAM state.

dc13909ed0 hw/arm/aspeed: Check for CPU types in machine_run_board_init()
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

954b33daee hw/block/block.c: improve confusing blk_check_size_and_read_all() error
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
backend name, the device id and device type name where appropriate.

This commit was created with scripts/clean-includes:

All .c should include qemu/osdep.h first.  The script performs three
related cleanups:

* Ensure .c files include qemu/osdep.h first.
* Including it in a .h is redundant, since the .c  already includes

* Likewise, including headers qemu/osdep.h includes is redundant.

988f244297 hw/char/imx_serial: Implement receive FIFO and ageing timer
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.

b0d1021ed9 fsl-imx6ul: Add various missing unimplemented devices
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.

3cdaf3dd4a virtio-blk: rename dataplane to ioeventfd
The dataplane code is really about using ioeventfd. It's used both for
IOThreads (what we think of as dataplane) and for the core virtio-pci
code's ioeventfd feature (which is enabled by default and used when no
IOThread has been specified). Rename the code to reflect this.

3bcc17f065 virtio-blk: move dataplane code into virtio-blk.c
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.

68c691ca99 s390x/pci: drive ISM reset from subsystem reset
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.

410c2a4d75 load_elf: fix iterator's type for elf file processing
j is used while loading an ELF file to byteswap segments'
data. If data is larger than 2GB an overflow may happen.
So j should be elf_word.

This commit fixes a minor bug: it's unlikely anybody is trying to
load ELF files with 2GB+ segments for wrong-endianness targets,
but if they did, it wouldn't work correctly.

c9948fdd02 hw/misc: Implement STM32L4x5 EXTI
Although very similar to the STM32F4xx EXTI, STM32L4x5 EXTI generates
more than 32 event/interrupt requests and thus uses more registers
than STM32F4xx EXTI which generates 23 event/interrupt requests.

10a8f7d25a hw/intc/loongarch_extioi: Add dynamic cpu number support
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.

5e90b8db38 hw/loongarch/virt: Set iocsr address space per-board rather than percpu
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.

8f6a487488 hw/pci-host/gpex: Define properties for MMIO ranges
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.

RISC-V also needs to use the same code to create fw_cfg in DSDT. So,
avoid code duplication by moving the code in arm and riscv to a device
specific file.

33995902b4 hw/arm/armv7m: alias the NVIC "num-prio-bits" property
A SoC will not have a direct access to the NVIC embedded in its ARM
core. By aliasing the "num-prio-bits" property similarly to what is
done for the "num-irq" one, a SoC can easily configure it on its

f221f641a2 vfio/spapr: Introduce a sPAPR VFIOIOMMU QOM interface
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.

fdaa774e67 vfio/container: Introduce a VFIOIOMMU QOM interface
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.

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.

b6948ab01d virtio-blk: add iothread-vq-mapping parameter
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
stale. Remove it.

cf03a152c5 qdev: add IOThreadVirtQueueMappingList property type
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"},...]}'

350147a871 qdev-properties: alias all object class properties
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.

ed18b1ed4f virtio-scsi: replace AioContext lock with tmf_bh_lock
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.

eaad0fe260 scsi: only access SCSIDevice->requests from one thread
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.

With LoongArch virt machine, there is low memory space with region
0--0x10000000, and high memory space with started from 0x90000000.
High memory space is aligned with 256M, it will be better if it is
aligned with 1G, which is super page aligned for 4K page size.

Currently linux kernel and uefi bios has no limitation with high
memory base address, it is ok to set high memory base address
with 0x80000000.

c455e011c6 hw: Replace anti-social QOM type names (again)
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.

4517c33c31 vfio: Make VFIOContainerBase poiner parameter const in VFIOIOMMUOps callbacks
Some of the callbacks in VFIOIOMMUOps pass VFIOContainerBase poiner,
those callbacks only need read access to the sub object of VFIOContainerBase.
So make VFIOContainerBase, VFIOContainer and VFIOIOMMUFDContainer as const
in these callbacks.

Local functions called by those callbacks also need same changes to avoid
build error.

da3e04b26f vfio/pci: Make vfio cdev pre-openable by passing a file handle
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].

c328e7e8ad vfio/pci: Introduce a vfio pci hot reset interface
Legacy vfio pci and iommufd cdev have different process to hot reset
vfio device, expand current code to abstract out pci_hot_reset callback
for legacy vfio, this same interface will also be used by iommufd
cdev vfio device.

Rename vfio_pci_hot_reset to vfio_legacy_pci_hot_reset and move it
into container.c.

vfio_pci_[pre/post]_reset and vfio_pci_host_match are exported so
they could be called in legacy and iommufd pci_hot_reset callback.

7e01bd80c1 hw/isa/vt82c686: Bring back via_isa_set_irq()
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.

(xilinx_spips_realize) and initialize their io memory region with different
mmio_ops passed through the class.  The size of the memory region is set to
the largest area (0x200 bytes for zynqmp-qspips) thus it is possible to write
out of s->regs[addr] in xilinx_spips_write for spips and qspips.

fd6a543d19 ide/pci: introduce pci_ide_update_mode() function
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.

d652866007 hw/arm/stm32f100: Report error when incorrect CPU is used
The 'stm32vldiscovery' machine ignores the CPU type requested by
the command line. This might confuse users, since the following
will create a machine with a Cortex-M3 CPU:

  $ qemu-system-aarch64 -M stm32vldiscovery -cpu neoverse-n1

Set the MachineClass::valid_cpu_types field (introduced in commit
c9cf636d48 "machine: Add a valid_cpu_types property").
Remove the now unused MachineClass::default_cpu_type field.

We now get:

  $ qemu-system-aarch64 -M stm32vldiscovery -cpu neoverse-n1
  qemu-system-aarch64: Invalid CPU type: neoverse-n1-arm-cpu
  The valid types are: cortex-m3-arm-cpu

Since the SoC family can only use Cortex-M3 CPUs, hard-code the
CPU type name at the SoC level, removing the QOM property
entirely.

b06f8b500d qdev: Rework array properties based on list visitor
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.

0d1dcb0bb1 ppc/pnv: Fix number of I2C engines and ports for power9/10
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.

263b81ee15 ppc/pnv: Add an I2C controller model
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

6d3910c9db hw/s390x/sclp: Have sclp_service_call[_protected]() take S390CPU*
"hw/s390x/sclp.h" is a header used by target-agnostic objects
(such hw/char/sclpconsole[-lm].c), thus can not use target-specific
types, such CPUS390XState.

Have sclp_service_call[_protected]() take a S390CPU pointer, which
is target-agnostic.

f3cb33255c target/ppc: Move PowerPCCPUClass definition to 'cpu.h'
The OBJECT_DECLARE_CPU_TYPE() macro forward-declares the
PowerPCCPUClass type. This forward declaration is sufficient
for code in hw/ to use the QOM definitions. No need to expose
the structure definition. Keep it local to target/ppc/ by
moving it to target/ppc/cpu.h.
