When we build IORT table with SMMUv3 and bypass iommu feature enabled,
we can no longer setup one map from RC to SMMUv3 covering the whole RIDs.
We need to walk the PCI bus and check whether the root bus will bypass
iommu, setup RC -> SMMUv3 -> ITS map for RC which will not bypass iommu.
When a SMMUv3 node exist, we setup the idmap from SMMUv3 to ITS
covering the whole RIDs, and only modify the map from RC to SMMUv3.
We build RC -> SMMUv3 -> ITS map for root bus with bypass_iommu
disabled, and build idmap from RC to ITS directly for the rest of
the whole RID space.
For example we run qemu with command line:
qemu/build/aarch64-softmmu/qemu-system-aarch64 \
-kernel arch/arm64/boot/Image \
-enable-kvm \
-cpu host \
-m 8G \
-smp 8,sockets=2,cores=4,threads=1 \
-machine virt,kernel_irqchip=on,gic-version=3,iommu=smmuv3,default_bus_bypass_iommu=true \
-drive file=./QEMU_EFI-pflash.raw,if=pflash,format=raw,unit=0,readonly=on \

We want to have safety margins for all tables based on the table type.
Let's move the maximum size logic into acpi_add_rom_blob() and make it
dependent on the table name, so we don't have to replicate for each and

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.

Qemu's ACPI table generation sets the fields OEM ID and OEM table ID
to "BOCHS " and "BXPCxxxx" where "xxxx" is replaced by the ACPI
table name.
Some games like Red Dead Redemption 2 seem to check the ACPI OEM ID
and OEM table ID for the strings "BOCHS" and "BXPC" and if they are
found, the game crashes(this may be an intentional detection
mechanism to prevent playing the game in a virtualized environment).
This patch allows you to override these default values.
The feature can be used in this manner:
qemu -machine oem-id=ABCDEF,oem-table-id=GHIJKLMN
The oem-id string can be up to 6 bytes in size, and the
oem-table-id string can be up to 8 bytes in size. If the string are
smaller than their respective sizes they will be padded with space.
If either of these parameters is not set, the current default values
will be used for the one missing.
Note that the the OEM Table ID field will not be extended with the
name of the table, but will use either the default name or the user
provided one.
This does not affect the -acpitable option (for user-defined ACPI
tables), which has precedence over -machine option.

On ARM/virt machine type QEMU currently reports an incorrect _UID in
ACPI.
The particular node in question is the primary PciRoot (PCI0 in ACPI),
which gets assigned PCI0 in ACPI UID and 0 in the
DevicePath. This is due to the _UID assigned to it by build_dsdt in
hw/arm/virt-acpi-build.c Which does not correspond to the primary PCI
identifier given by pcibus_num in hw/pci/pci.c
In UEFI v2.8, section "10.4.2 Rules with ACPI _HID and _UID" ends with
the paragraph,
Root PCI bridges will use the plug and play ID of PNP0A03, This will
be stored in the ACPI Device Path _HID field, or in the Expanded
ACPI Device Path _CID field to match the ACPI name space. The _UID
in the ACPI Device Path structure must match the _UID in the ACPI
name space.
(See especially the last sentence.)
A similar bug has been reported on i386, on that architecture it has
been reported to confuse at least macOS which uses ACPI UIDs to build
the DevicePath for NVRAM boot options, while OVMF firmware gets them via
an internal channel through QEMU. When UEFI firmware and ACPI have
different values, this makes the underlying operating system unable to
report its boot option.

The flash device is exclusively for the host-controlled firmware, so
we should not expose it to the OS. Exposing it risks the OS messing
with it, which could break firmware runtime services and surprise the
OS when all its changes disappear after reboot.
As firmware needs the device and uses DT, we leave the device exposed
there. It's up to firmware to remove the nodes from DT before sending
it on to the OS. However, there's no need to force firmware to remove
tables from ACPI (which it doesn't know how to do anyway), so we
simply don't add the tables in the first place. But, as we've been
adding the tables for quite some time and don't want to change the
default hardware exposed to versioned machines, then we only stop
exposing the flash device tables for 5.1 and later machine types.

The original code defines a named object for the resource template but
then returns the resource template object itself; the resulted output
is like below:
Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings
{
Name (RBUF, ResourceTemplate ()
{
WordBusNumber (ResourceProducer, MinFixed, MaxFixed, PosDecode,
0x0000, // Granularity

Return (ResourceTemplate ()

WordBusNumber (ResourceProducer, MinFixed, MaxFixed, PosDecode,

0x0000, // Range Minimum
0x00FF, // Range Maximum
0x0000, // Translation Offset

}
So the named object "RBUF" is actually useless. The more natural way
is to return RBUF instead, or simply drop RBUF definition.
Choose the latter one to simplify the code.

The address field in each _PRT mapping package should be constructed
with high word for device# and low word for function#, so it is wrong
to use bus_no as the high word. The existing code adds a bunch useless
entries with device #s above 31. Enumerate all possible slots
(i.e. PCI_SLOT_MAX) instead.

According to ACPI spec, _ADR should be used for device on a bus that
has a standard enumeration algorithm, but not for device which is on
system bus and must be enumerated by OSPM. And it is not recommended
to contain both _HID and _ADR in a single device.
See ACPI 6.3, section 6.1, top of page 343:
A device object must contain either an _HID object or an _ADR object,
but should not contain both.
