Philippe Mathieu-Daudé 0068b069c3 hw/sysbus: Inline and remove sysbus_add_io()
sysbus_add_io(...) is a simple wrapper to
memory_region_add_subregion(get_system_io(), ...).
It is used in 3 places; inline it directly.

Rationale: we want to move to an explicit I/O bus,
rather that an implicit one. Besides in heterogeneous
setup we can have more than one I/O bus.

Philippe Mathieu-Daudé 40f27a785f hw/input/pckbd: Open-code i8042_setup_a20_line() wrapper
Since the named GPIO lines are a "public" interface to the device,
we can directly call qdev_connect_gpio_out_named(), making it
consistent with how the other A20 input source (port92) is wired.

Thomas Huth 04b86ccb5d hw/hppa/Kconfig: Fix building with "configure --without-default-devices"
When running "configure" with "--without-default-devices", building
of qemu-system-hppa currently fails with:

 /usr/bin/ld: libqemu-hppa-softmmu.fa.p/hw_hppa_machine.c.o: in function `machine_HP_common_init_tail':
 hw/hppa/machine.c:399: undefined reference to `usb_bus_find'

 collect2: error: ld returned 1 exit status
 ninja: build stopped: subcommand failed.
 make: *** [Makefile:162: run-ninja] Error 1

And after fixing this, the qemu-system-hppa binary refuses to run
due to the missing 'pci-ohci' and 'pci-serial' devices. Let's add
the right config switches to fix these problems.

Paolo Bonzini 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.

Xiaoyao Li 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.

because the ISASuperIODevice struct adds fields to ISADevice but the type does

Fix this by specifying the instance_size already in the superclass.

Peter Maydell 273a70ae82 hw/arm/mps3r: Initial skeleton for mps3-an536 board
The AN536 is another FPGA image for the MPS3 development board. Unlike
the existing FPGA images we already model, this board uses a Cortex-R
family CPU, and it does not use any equivalent to the M-profile
"Subsystem for Embedded" SoC-equivalent that we model in hw/arm/armsse.c.
It's therefore more convenient for us to model it as a completely
separate C file.

This commit adds the basic skeleton of the board model, and the
code to create all the RAM and ROM. We assume that we're probably
going to want to add more images in future, so use the same
base class/subclass setup that mps2-tz.c uses, even though at
the moment there's only a single subclass.

Following commits will add the CPUs and the peripherals.

Peter Maydell 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.

Peter Maydell 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.)

Peter Maydell f94d58f260 hw/pci-host/raven.c: Mark raven_io_ops as implementing unaligned accesses
The raven_io_ops MemoryRegionOps is the only one in the source tree
which sets .valid.unaligned to indicate that it should support
unaligned accesses and which does not also set .impl.unaligned to
indicate that its read and write functions can do the unaligned
handling themselves.  This is a problem, because at the moment the
core memory system does not implement the support for handling
unaligned accesses by doing a series of aligned accesses and
combining them (system/memory.c:access_with_adjusted_size() has a
TODO comment noting this).

Fortunately raven_io_read() and raven_io_write() will correctly deal
with the case of being passed an unaligned address, so we can fix the
missing unaligned access support by setting .impl.unaligned in the
MemoryRegionOps struct.

Manos Pitsidianakis 588a09dace virtio-gpu-rutabaga.c: override resource_destroy method
When the Rutabaga GPU device frees resources, it calls
rutabaga_resource_unref for that resource_id. However, when the generic
VirtIOGPU functions destroys resources, it only removes the
virtio_gpu_simple_resource from the device's VirtIOGPU->reslist list.
The rutabaga resource associated with that resource_id is then leaked.

This commit overrides the resource_destroy class method introduced in
the previous commit to fix this.

Akihiko Odaki e8ddec5805 hw/smbios: Fix OEM strings table option validation
qemu_smbios_type11_opts did not have the list terminator and that
resulted in out-of-bound memory access. It also needs to have an element
for the type option.

Jonathan Cameron 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.

Whilst the reported version was 1 so there should be no changes,
a couple of fields (where the value 0 was valid) were not
defined. Make those explicit and update references to be based
on CXL r3.1.

Jonathan Cameron d9ae5802f6 hw/i386: Fix _STA return value for ACPI0017
Found whilst testing a series for the linux kernel that actually
bothers to check if enabled is set. 0xB is the option used
for vast majority of DSDT entries in QEMU.
It is a little odd for a device that doesn't really exist and
is simply a hook to tell the OS there is a CEDT table but 0xB
seems a reasonable choice and avoids need to special case
this device in the OS.

Means:
* Device present.
* Device enabled and decoding it's resources.
* Not shown in UI
* Functioning properly
* No battery (on this device!)
