[PATCH-for-10.0 v2 00/14] hw/arm: Tests & ACPI tables fixes for 10.0

[Philippe Mathieu-Daudé]

Hi,

I tried to gather all the hw/arm/-related patches for
the GitLab issues tagged for 10.0.

First, trivial ones fixing / disabling broken tests;
then disable the VMapple machine (not sure about it);
finally fix ACPI tables for '-M its=off' CLI option.

While polishing the series, I noticed MST mentioning
the ACPI changes are likely too late:
https://lore.kernel.org/qemu-devel/20250403100406-mutt-send-email-mst@kernel.org/
I'll defer that jugement to Alex :)

Regards,

Phil.

[PATCH-for-10.0 v2 01/14] tests/functional/test_aarch64_rme_virt: fix sporadic failure

[Philippe Mathieu-Daudé]

From: Pierrick Bouvier <pierrick.bouvier@linaro.org>

This test was randomly failing on our CI, and on dev machines,
especially with QEMU debug builds.

From the information collected, it's related to an implementation choice
in edk2 QEMU virt support. The workaround is to disable KASLR, to avoid
accessing protected memory.
Note: this is *not* needed for the similar test_aarch64_rme_sbsaref.

More information is available on the associated GitLab issue.

[PATCH-for-10.0 v2 02/14] tests/functional: Add a decorator for skipping tests on particular OS

[Philippe Mathieu-Daudé]

Since tests might be failing on some operating systems,
introduce the skipIfOperatingSystem() decorator.

"permitted ones" sounds like you'd need to specify the ones that are allowed 
to run the test, but it's rather the other way round, you have to specify 
the ones that are not able to run the test. I'd suggest to rewrite the 
comment accordingly.

Same here, maybe rather: "running on an OS (%s) that is not able to run this 
test" ?

[PATCH-for-10.0 v2 04/14] tests/qtest: Skip Aarch64 VMapple machine

[Philippe Mathieu-Daudé]

First, the VMapple machine only works with the ARM 'host' CPU
type, which isn't accepted for QTest:

  $ qemu-system-aarch64 -M vmapple -accel qtest
  qemu-system-aarch64: The 'host' CPU type can only be used with KVM or HVF

Second, the QTest framework expects machines to be createable
without specifying optional arguments, however the VMapple
machine requires few of them:

  $ qemu-system-aarch64 -M vmapple -accel qtest
  qemu-system-aarch64: No firmware specified

  $ qemu-system-aarch64 -M vmapple -accel qtest -bios /dev/null
  qemu-system-aarch64: No AUX device. Please specify one as pflash drive.

Restrict this machine with QTest so we can at least run check-qtest,
otherwise we get:

  $ make check-qtest-aarch64
  qemu-system-aarch64: The 'host' CPU type can only be used with KVM or HVF
  Broken pipe
  ../tests/qtest/libqtest.c:199: kill_qemu() tried to terminate QEMU process but encountered exit status 1 (expected 0)

[PATCH-for-10.0? v2 06/14] hw/arm/virt: Remove pointless VirtMachineState::tcg_its field

[Philippe Mathieu-Daudé]

VirtMachineState::tcg_its has the same value of
VirtMachineClass::no_tcg_its. Directly use the latter,
removing the former.

No it doesn't.

This is a stupidly verbose not.
But at least the names had correct logic.
Therefore all of the uses you replace need inversion.

[PATCH-for-10.0? v2 07/14] hw/intc/gicv3_its: Do not check its_class_name() for NULL

[Philippe Mathieu-Daudé]

Since commit cc5e719e2c8 ("kvm: require KVM_CAP_SIGNAL_MSI"),
its_class_name() single implementation doesn't return NULL
anymore. Update the prototype docstring, and remove the
pointless checks.

[PATCH-for-10.0? v2 10/14] qtest/bios-tables-test: Add test for -M virt, its=off

[Philippe Mathieu-Daudé]

Add the use case reported as issue #2886 [*]. The test
passes while it shouldn't. We are going to fix that in
the following commits.

[PATCH-for-10.0? v2 11/14] qtest/bios-tables-test: Whitelist aarch64/virt 'its_off' variant blobs

[Philippe Mathieu-Daudé]

We are going to fix the test_acpi_aarch64_virt_tcg_its_off()
test. In preparation, copy the ACPI tables which will be
altered as 'its_off' variants, and whitelist them.

ditto

and the same for blobs below as well (commit message for those shall
contain relevant diff for changes or explain why there is none).
blobs update seems to be a bit confusing at this point (aka unexpected).

looking at this patch, I'd make a copy 1st, then '.variant = ".its_off",' patch
and only then whitelist right before patches that would actually change
tables.

[PATCH-for-10.0? v2 12/14] hw/arm/virt-acpi: Always build IORT table (even with GIC ITS disabled)

[Philippe Mathieu-Daudé]

Citing Gustavo [*]:

  Gating IORT table generation entirely based on the presence
  of ITS looks wrong because IORT table has data beyond GIC ITS,
  like for SMMUv3 etc..

[PATCH-for-10.0? v2 13/14] hw/arm/virt-acpi: Do not advertise disabled GIC ITS

[Philippe Mathieu-Daudé]

GIC ITS can be disabled at runtime using '-M its=off',
which sets VirtMachineState::its = false. Check this
field to avoid advertising the ITS in the MADT table.

It's confusing have both no_its and its,
it would be better to lean this mess up (i.e dedup or rename if something is poorly named)

What about:

class: s/no_its/!its_createable/ or !its_usable
state: s/its/its_created/ or its_used or its_in_use

looking at the code what we are essentially doing with variables in class,
is selecting its device type. And then playing scattered if/then game to decide
which 'its' to create or not create.
can we make something like this instead:

 machine_foo_class_init_vX():
  vmc->its_type = NULL;

 machine_foo_class_init_vX+1():
  vmc->its_type = accel_get_its_type()
 
and then elsewhere:

if(vmc->its_type && vms->its_enabled)
    create_its(vmc->its_type)
