create mode 100644 hw/arm/mps3r.c

The API does not generate an error for setting ASYNC | SYNC; that merely

constrains the selection vs the per-cpu default. For qemu linux-user,

choose SYNC as the default.

2.34.1

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.

Suppress the deprecation warning when we're running under qtest,

to avoid "make check" including warning messages in its output.

We deliberately don't include qtests_npcm7xx in qtests_aarch64,

because we already get the coverage of those tests via qtests_arm,

and we don't want to use extra CI minutes testing them twice.

In commit 327b680877b79c4b we added it to qtests_aarch64; revert

that change.

Allow changes to the virt GTDT -- we are going to add the IRQ

entry for a new timer to it.

2.34.1

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.)
