Commit 4c70875372 ("pci: advertise a page aligned ATS") advertises
the page aligned via ATS capability (RO) to unbrek recent Linux IOMMU
drivers since 5.2. But it forgot the compat the capability which
breaks the migration from old machine type:
(qemu) qemu-kvm: get_pci_config_device: Bad config data: i=0x104 read:
0 device: 20 cmask: ff wmask: 0 w1cmask:0
This patch introduces a new parameter "x-ats-page-aligned" for
virtio-pci device and turns it on for machine type which is newer than
5.1.

After introducing non-scalar machine properties, it would be preferrable
to have a single acpitable property which includes both generic

passed via -acpitable.
Do not saddle ourselves with legacy oem-id and oem-table-id
properties, instead mark them as experimental.

The definition S390_ADAPTER_SUPPRESSIBLE was moved to "cpu.h", per
suggestion of Thomas Huth. From interface design perspective, IMHO, not
a good thing as it belongs to the public interface of
css_register_io_adapters(). We did this because CONFIG_KVM requeires
NEED_CPU_H and Thomas, and other commenters did not like the
consequences of that.
Moving the interrupt related declarations to s390_flic.h was suggested
by Cornelia Huck.

For accesses to rom blob data before or during reset, we have a
function rom_ptr() which looks for a rom blob that would be loaded to
the specified address, and returns a pointer into the rom blob data
corresponding to that address. This allows board or CPU code to say
"what is the data that is going to be loaded to this address?".
However, this function does not take account of memory region
aliases. If for instance a machine model has RAM at address
0x0000_0000 which is aliased to also appear at 0x1000_0000, a
rom_ptr() query for address 0x0000_0000 will only return a match if
the guest image provided by the user was loaded at 0x0000_0000 and
not if it was loaded at 0x1000_0000, even though they are the same
RAM and a run-time guest CPU read of 0x0000_0000 will read the data
loaded to 0x1000_0000.
Provide a new function rom_ptr_for_as() which takes an AddressSpace
argument, so that it can check whether the MemoryRegion corresponding
to the address is also mapped anywhere else in the AddressSpace and
look for rom blobs that loaded to that alias.

A clock is added by commit aac63e0e6e ("hw/char/pl011: add a clock

causes backwards migration failure from upstream to downstream (v5.1.0)
when the machine type is specified with virt-5.1.
This fixes the issue by following instructions from section "Connecting
subsections to properties" in docs/devel/migration.rst. With this applied,
the PL011 clock is migrated based on the machine type.

The resizeable memory region / RAMBlock that is created for the cmd blob
has a maximum size of whole host pages (e.g., 4k), because RAMBlocks
work on full host pages. In addition, in i386 ACPI code:
acpi_align_size(tables->linker->cmd_blob, ACPI_BUILD_ALIGN_SIZE);
makes sure to align to multiples of 4k, padding with 0.
For example, if our cmd_blob is created with a size of 2k, the maximum
size is 4k - we cannot grow beyond that. Growing might be required
due to guest action when rebuilding the tables, but also on incoming
migration.
This automatic generation of the maximum size used to be sufficient,
however, there are cases where we cross host pages now when growing at
runtime: we exceed the maximum size of the RAMBlock and can crash QEMU when
trying to resize the resizeable memory region / RAMBlock:
$ build/qemu-system-x86_64 --enable-kvm \
-machine q35,nvdimm=on \
-smp 1 \
-cpu host \
-m size=2G,slots=8,maxmem=4G \
-object memory-backend-file,id=mem0,mem-path=/tmp/nvdimm,size=256M \
-device nvdimm,label-size=131072,memdev=mem0,id=nvdimm0,slot=1 \
-nodefaults \
-device vmgenid \
-device intel-iommu
Results in:
Unexpected error in qemu_ram_resize() at ../softmmu/physmem.c:1850:
qemu-system-x86_64: Size too large: /rom@etc/table-loader:
0x2000 > 0x1000: Invalid argument
In this configuration, we consume exactly 4k (32 entries, 128 bytes each)
when creating the VM. However, once the guest boots up and maps the MCFG,
we also create the MCFG table and end up consuming 2 additional entries
(pointer + checksum) -- which is where we try resizing the memory region
/ RAMBlock, however, the maximum size does not allow for it.
Currently, we get the following maximum sizes for our different
mutable tables based on behavior of resizeable RAMBlock:
hw table max_size
------- ---------------------------------------------------------
virt "etc/acpi/tables" ACPI_BUILD_TABLE_MAX_SIZE (0x200000)
virt "etc/table-loader" HOST_PAGE_ALIGN(initial_size)
virt "etc/acpi/rsdp" HOST_PAGE_ALIGN(initial_size)
i386 "etc/acpi/tables" ACPI_BUILD_TABLE_MAX_SIZE (0x200000)
i386 "etc/table-loader" HOST_PAGE_ALIGN(initial_size)
i386 "etc/acpi/rsdp" HOST_PAGE_ALIGN(initial_size)
microvm "etc/acpi/tables" ACPI_BUILD_TABLE_MAX_SIZE (0x200000)
microvm "etc/table-loader" HOST_PAGE_ALIGN(initial_size)
microvm "etc/acpi/rsdp" HOST_PAGE_ALIGN(initial_size)
Let's set the maximum table size for "etc/table-loader" to 64k, so we
can properly grow at runtime, which should be good enough for the future.
Migration is not concerned with the maximum size of a RAMBlock, only
with the used size - so existing setups are not affected. Of course, we
cannot migrate a VM that would have crash when started on older QEMU from
new QEMU to older QEMU without failing early on the destination when
synchronizing the RAM state:
qemu-system-x86_64: Size too large: /rom@etc/table-loader: 0x2000 > 0x1000: Invalid argument
qemu-system-x86_64: error while loading state for instance 0x0 of device 'ram'
qemu-system-x86_64: load of migration failed: Invalid argument
We'll refactor the code next, to make sure we get rid of this implicit
behavior for "etc/acpi/rsdp" as well and to make the code easier to
grasp.

In x86/ACPI world, linux distros are using predictable
network interface naming since systemd v197. Which on
QEMU based VMs results into path based naming scheme,
that names network interfaces based on PCI topology.
With itm on has to plug NIC in exactly the same bus/slot,
which was used when disk image was first provisioned/configured
or one risks to loose network configuration due to NIC being
renamed to actually used topology.
That also restricts freedom to reshape PCI configuration of
VM without need to reconfigure used guest image.
systemd also offers "onboard" naming scheme which is
preferred over PCI slot/topology one, provided that
firmware implements:
"
PCI Firmware Specification 3.1
4.6.7. DSM for Naming a PCI or PCI Express Device Under
Operating Systems
"
that allows to assign user defined index to PCI device,
which systemd will use to name NIC. For example, using
-device e1000,acpi-index=100
guest will rename NIC to 'eno100', where 'eno' is default
prefix for "onboard" naming scheme. This doesn't require
any advance configuration on guest side to com in effect
at 'onboard' scheme takes priority over path based naming.
Hope is that 'acpi-index' it will be easier to consume by
management layer, compared to forcing specific PCI topology
and/or having several disk image templates for different
topologies and will help to simplify process of spawning
VM from the same template without need to reconfigure
guest NIC.
This patch adds, 'acpi-index'* property and wires up
a 32bit register on top of pci hotplug register block
to pass index value to AML code at runtime.
Following patch will add corresponding _DSM code and
wire it up to PCI devices described in ACPI.

For testing, it can be useful to simulate an enormous amount of memory
(e.g. 2^64 RAM). This adds an MMIO device that acts as sparse memory.
When something writes a nonzero value to a sparse-mem address, we
allocate a block of memory. For now, since the only user of this device
is the fuzzer, we do not track and free zeroed blocks. The device has a
very low priority (so it can be mapped beneath actual RAM, and virtual
device MMIO regions).

This patch adds fan_splitters (split IRQs) in NPCM7XX boards. Each fan
splitter corresponds to 1 PWM output and can connect to multiple fan
inputs (MFT devices).
In NPCM7XX boards(NPCM750 EVB and Quanta GSJ boards), we initializes
these splitters and connect them to their corresponding modules
according their specific device trees.

This patch implements Multi Function Timer (MFT) module for NPCM7XX.
This module is mainly used to configure PWM fans. It has just enough
functionality to make the PWM fan kernel module work.
The module takes two input, the max_rpm of a fan (modifiable via QMP)
and duty cycle (a GPIO from the PWM module.) The actual measured RPM
is equal to max_rpm * duty_cycle / NPCM7XX_PWM_MAX_DUTY. The RPM is
measured as a counter compared to a prescaled input clock. The kernel
driver reads this counter and report to user space.

This patch adds GPIOs in NPCM7xx PWM module for its duty values.
The purpose of this is to connect it to the MFT module to provide
an input for measuring a PWM fan's RPM. Each PWM module has
NPCM7XX_PWM_PER_MODULE of GPIOs, each one corresponds to
one PWM instance and can connect to multiple fan instances in MFT.

Prior to commit f2ce39b4f0 a MachineClass kvm_type method
only needed to be registered to ensure it would be executed.
With commit f2ce39b4f0 a kvm-type machine property must also
be specified. hw/arm/virt relies on the kvm_type method to pass
its selected IPA limit to KVM, but this is not exposed as a
machine property. Restore the previous functionality of invoking
kvm_type when it's present.

Add a model of the Xilinx Versal Accelerator RAM (XRAM).
This is mainly a stub to make firmware happy. The size of
the RAMs can be probed. The interrupt mask logic is
modelled but none of the interrups will ever be raised
unless injected.
