The Cortex-A55 is one of the newer armv8.2+ CPUs; in particular
it supports the Privileged Access Never (PAN) feature. Add
a model of this CPU, so you can use a CPU type on the virt
board that models a specific real hardware CPU, rather than
having to use the QEMU-specific "max" CPU type.

Use the base_memmap to build the SMBIOS 19 table which provides the address
mapping for a Physical Memory Array (from spec [1] chapter 7.20).
This was present on i386 from commit c97294ec1b
("SMBIOS: Build aggregate smbios tables and entry point").
[1] https://www.dmtf.org/sites/default/files/standards/documents/DSP0134_3.5.0.pdf
The absence of this table is a breach of the specs and is
detected by the FirmwareTestSuite (FWTS), but it doesn't
cause any known problems for guest OSes.

The 3 high memory regions are usually enabled by default, but they may
be not used. For example, VIRT_HIGH_GIC_REDIST2 isn't needed by GICv2.
This leads to waste in the PA space.
Add properties ("highmem-redists", "highmem-ecam", "highmem-mmio") to
allow users selectively disable them if needed. After that, the high
memory region for GICv3 or GICv4 redistributor can be disabled by user,
the number of maximal supported CPUs needs to be calculated based on
'vms->highmem_redists'. The follow-up error message is also improved
to indicate if the high memory region for GICv3 and GICv4 has been
enabled or not.

After the improvement to high memory region address assignment is
applied, the memory layout can be changed, introducing possible
migration breakage. For example, VIRT_HIGH_PCIE_MMIO memory region
is disabled or enabled when the optimization is applied or not, with
the following configuration. The configuration is only achievable by
modifying the source code until more properties are added to allow
users selectively disable those high memory regions.
pa_bits = 40;
vms->highmem_redists = false;
vms->highmem_ecam = false;
vms->highmem_mmio = true;
# qemu-system-aarch64 -accel kvm -cpu host \
-machine virt-7.2,compact-highmem={on, off} \
-m 4G,maxmem=511G -monitor stdio
Region compact-highmem=off compact-highmem=on
----------------------------------------------------------------
MEM [1GB 512GB] [1GB 512GB]
HIGH_GIC_REDISTS2 [512GB 512GB+64MB] [disabled]
HIGH_PCIE_ECAM [512GB+256MB 512GB+512MB] [disabled]
HIGH_PCIE_MMIO [disabled] [512GB 1TB]
In order to keep backwords compatibility, we need to disable the
optimization on machine, which is virt-7.1 or ealier than it. It
means the optimization is enabled by default from virt-7.2. Besides,
'compact-highmem' property is added so that the optimization can be
explicitly enabled or disabled on all machine types by users.

There are three high memory regions, which are VIRT_HIGH_REDIST2,
VIRT_HIGH_PCIE_ECAM and VIRT_HIGH_PCIE_MMIO. Their base addresses
are floating on highest RAM address. However, they can be disabled
in several cases.
(1) One specific high memory region is likely to be disabled by
code by toggling vms->highmem_{redists, ecam, mmio}.
(2) VIRT_HIGH_PCIE_ECAM region is disabled on machine, which is
'virt-2.12' or ealier than it.
(3) VIRT_HIGH_PCIE_ECAM region is disabled when firmware is loaded
on 32-bits system.
(4) One specific high memory region is disabled when it breaks the
PA space limit.
The current implementation of virt_set_{memmap, high_memmap}() isn't
optimized because the high memory region's PA space is always reserved,
regardless of whatever the actual state in the corresponding
vms->highmem_{redists, ecam, mmio} flag. In the code, 'base' and
'vms->highest_gpa' are always increased for case (1), (2) and (3).
It's unnecessary since the assigned PA space for the disabled high
memory region won't be used afterwards.
Improve the address assignment for those three high memory region by
skipping the address assignment for one specific high memory region if
it has been disabled in case (1), (2) and (3). The memory layout may
be changed after the improvement is applied, which leads to potential
migration breakage. So 'vms->highmem_compact' is added to control if
the improvement should be applied. For now, 'vms->highmem_compact' is
set to false, meaning that we don't have memory layout change until it
becomes configurable through property 'compact-highmem' in next patch.

Update the Fixed ACPI Description Table (FADT) to revision 6.0 of the ACPI
specification adding the field "Hypervisor Vendor Identity".
This field's description states the following: "64-bit identifier of hypervisor
vendor. All bytes in this field are considered part of the vendor identity.
These identifiers are defined independently by the vendors themselves,
usually following the name of the hypervisor product. Version information
should NOT be included in this field - this shall simply denote the vendor's
name or identifier. Version information can be communicated through a
supplemental vendor-specific hypervisor API. Firmware implementers would
place zero bytes into this field, denoting that no hypervisor is present in

When we direct boot a kernel on a CPU which emulates EL3, we need to

specifies:

For CPUs with FEAT_HCX support this includes:
- SCR_EL3.HXEn (bit 38) must be initialised to 0b1.
but we forgot to do this when implementing FEAT_HCX, which would mean
that a guest trying to access the HCRX_EL2 register would crash.

When we direct boot a kernel on a CPU which emulates EL3, we need
to set up the EL3 system registers as the Linux kernel documentation
specifies:
https://www.kernel.org/doc/Documentation/arm64/booting.rst
For SVE and SME this includes:
- ZCR_EL3.LEN must be initialised to the same value for all CPUs the
kernel is executed on.
- SMCR_EL3.LEN must be initialised to the same value for all CPUs the
kernel will execute on.
Although we are technically compliant with this, the "same value" we
currently use by default is the reset value of 0. This will end up
forcing the guest kernel's SVE and SME vector length to be only the
smallest supported length.
Initialize the vector length fields to their maximum possible value,
which is 0xf. If the implementation doesn't actually support that
vector length then the effective vector length will be constrained
down to the maximum supported value at point of use.
This allows the guest to use all the vector lengths the emulated CPU
supports (by programming the _EL2 and _EL1 versions of these
registers.)

A mx25l25635f chip model is generally found on these machines. It's
newer and uses 4B opcodes which is better to exercise the support in

The "msi-parent" property can be used on the PCI node when MSIs do not
contain sideband data (device IDs) [1]. In QEMU, MSI transactions
contain the requester ID, so the PCI node should use the "msi-map"
property instead of "msi-parent". In our case the property describes an
identity map between requester ID and sideband data.
This fixes a warning when passing the DTB generated by QEMU to dtc,
following a recent change to the GICv3 node:

Currently armv7m_load_kernel() takes the size of the block of memory
where it should load the initial guest image, but assumes that it
should always load it at address 0. This happens to be true of all
our M-profile boards at the moment, but it isn't guaranteed to always
be so: M-profile CPUs can be configured (via init-svtor and
init-nsvtor, which match equivalent hardware configuration signals)
to have the initial vector table at any address, not just zero. (For
instance the Teeny board has the boot ROM at address 0x0200_0000.)
Add a base address argument to armv7m_load_kernel(), so that
callers now pass in both base address and size. All the current
callers pass 0, so this is not a behaviour change.

Side notes:
* our M-profile implementation is always little-endian (that is, it
makes the IMPDEF choice that the read-only AIRCR.ENDIANNESS is 0)
* if we did want to handle big-endian ELF files here we should do it
the way that hw/arm/boot.c:arm_load_elf() does, by looking at the

This change moves the code that connects the SoC UART's to serial_hd's
to the machine.
It makes each UART a proper child member of the SoC, and then allows the
machine to selectively initialize the chardev for each UART with a
serial_hd.
This should preserve backwards compatibility, but also allow multi-SoC
boards to completely change the wiring of serial devices from the
command line to specific SoC UART's.
This also removes the uart-default property from the SoC, since the SoC
doesn't need to know what UART is the "default" on the machine anymore.

refactoring, and another test image for the ast1030:

To support multiple SoC's running simultaneously, we need a unique name for
each RAM region. DRAM is created by the machine, but SRAM is created by the
SoC, since in hardware it is part of the SoC's internals.
We need a way to uniquely identify each SRAM region though, for VM
migration. Since each of the SoC's CPU's has an index which identifies it
uniquely from other CPU's in the machine, we can use the index of any of the
CPU's in the SoC to uniquely identify differentiate the SRAM name from other
SoC SRAM's. In this change, I just elected to use the index of the first CPU
in each SoC.
