Hi; here's the first target-arm pullreq for the 9.0 cycle.
The bulk of this is some cleanup/refactoring in the Arm
KVM code.
thanks

Hi; here's another Arm pullreq: the big thing in here is
Bernhard's imx8mp-evk board model; there's also various cleanup
type patches from me, as well as some bugfixes.
thanks

Hi; here's an arm pullreq. Most of it is refactoring and similar
cleanup type patches. I just switched to using gitlab as the
host for pullreq tags; I think I got the config change right but
let me know if this is broken somehow.
thanks

I've both publicly and private been digging around the Apple Silicon HVF code,
and use it daily as part of my job. I feel I have a solid understanding of it,
so I thought I'd step up and assist.
I've added myself as reviewer to the common "HVF" as well, to be informed of
changes that might affect the Apple Silicon HVF code, which will be my primary
focus.

According to the Arm A-profile A64 Instruction Set Architecture,
RETA[AB] should be decoded as UNDEF if the pauth feature is not
implemented.
We got this right in the initial implementation, but accidentally
dropped the feature-check when we converted these insns to
decodetree.

This new header contains macros that define aarch64 registers.
In a subsequent patch, this will be replaced by a more exhaustive
version that will be generated from linux arch/arm64/tools/sysreg
file. Those macros are sufficient to migrate the storage of those
ID regs from named fields in isar struct to an array cell.
[CH: reworked to use different structures]
[CH: moved accessors from the patches first using them to here,
dropped interaction with writable registers, which will happen
later]
[CH: use DEF magic suggested by rth]

Since commit cc5e719e2c8 ("kvm: require KVM_CAP_SIGNAL_MSI"), the single
implementation of its_class_name() no longer returns NULL (it now always
returns a valid char pointer). Hence, update the prototype docstring and
remove the tautological checks that use the its_class_name() returned
value.

Because 'tcg_its' in the machine instance is set based on the machine
class’s negated variable 'no_tcg_its', 'tcg_its' is the opposite of
'no_tcg_its' and hence the code in question can be simplified as:
tcg_its = !no_tcg_its.

When building the Root Complex table, the comment about the code that
maps the RC node to SMMU node is misleading because it reads
"RC -> SMMUv3 -> ITS", but the code is only mapping the RCs IDs to the
SMMUv3 node. The step of mapping from the SMMUv3 IDs to the ITS Group
node is actually defined in another table (in the SMMUv3 node). So
change the comment to read "RC -> SMMUv3" instead.

Arm64 GIC ITS (Interrupt Translation Service) is an optional piece of
hardware introduced in GICv3 and, being optional, it can be disabled
in QEMU aarch64 VMs that support it using machine option "its=off",
like, for instance: "-M virt,its=off".
In ACPI, the ITS is advertised, if present, in the MADT (aka APIC)
table, while the ID mappings from the Root Complex (RC) and from the
SMMU nodes to the ITS Group nodes are described in the IORT table.
This new test verifies that when the "its=off" option is passed to the
machine the ITS-related data is correctly pruned from the ACPI tables.
The new blobs for this test will be added in a following commit.

new variant, .its_off, that requires variations of the MADT and IORT

Currently, the ITS Group nodes in the IORT table and the GIC ITS Struct
in the MADT table are always generated, even if GIC ITS is not available
on the machine.
This commit fixes it by not generating the ITS Group nodes, not mapping
any other node to them, and not advertising the GIC ITS in the MADT
table, when GIC ITS is not available on the machine.
Since the fix changes the MADT and IORT tables, add the blobs for the
"its=off" test to the allow list and update them in the next commit.
This commit also renames the smmu_idmaps and its_idmaps variables in
build_iort() to rc_smmu_idmaps and rc_its_idmaps, respectively, to make
it clearer which nodes are involved in the mappings associated with
these variables.

Update blobs for the its=off test on aarch64 after fix.
Basically, all structs related to ITS are gone in MADT and IORT
tables after the fix (previously ITS was not properly disabled
when "its=off" option was passed to the machine).

Currently only the TCG and qtest accelerators can handle an EL3
guest. Instead of making the condition check be "fail if KVM or HVF"
(an exclude-list), make it a be "allow if TCG or qtest" (an
accept-list).
This is better for if/when we add new accelerators, as it makes the
default be that we forbid an EL3 guest. This is the most likely to
be correct and also "fails safe"; if the new accelerator really can
support EL3 guests then the implementor will see that they need to
add it to the accept-list.

Currently QEMU only support accelerating EL0 and EL1, so features
requiring EL2 (like virtualization) or EL3 must be emulated with TCG.
On macOS this test fails:

This test allows to document and exercise device passthrough, using a
nested virtual machine setup. Two disks are generated and passed to the
VM, and their content is compared to original images.
Guest and nested guests commands are executed through two scripts, and
init used in both system is configured to trigger a kernel panic in case
any command fails. This is more reliable and readable than executing all
commands through prompt injection and trying to guess what failed.
Initially, this test was supposed to test smmuv3 nested emulation
(combining both stages of translation), but I could not find any setup
(kernel + vmm) able to do the passthrough correctly, despite several
tries.

FYI when using:
C compiler for the host machine: gcc-15 (gcc 15.1.0 "gcc-15 (Homebrew
GCC 15.1.0) 15.1.0")
on macOS, I'm getting:
