The first patch is a small cleanup. The next two patches update tests to
disable PIT so that SVM AVIC can be exercized. The last patch adds a
test for x1apic-split.
The last patch causes aliased apic_id ipi test to fail with older qemu
versions. Qemu v6.2 and before used to enable
KVM_X2APIC_API_USE_32BIT_IDS KVM quirk in some scenarios, and this was
changed in commit dc89f32d92bb ("target/i386: Fix sanity check on max
APIC ID / X2APIC enablement") to be enabled only if there are > 255
vcpus. The KUT test does talk about this assumption in a comment:
/*
* By default, KVM doesn't follow the x86 APIC architecture for aliased
* APIC IDs if userspace has enabled KVM_X2APIC_API_USE_32BIT_IDS.
* If x2APIC is supported, assume the userspace VMM has enabled 32-bit
* IDs and thus activated KVM's quirk. Delete this code to run the
* aliasing test on x2APIC CPUs, e.g. to run it on bare metal.
*/
That looks to suggest that this is an expected failure, but it would be
good to get confirmation on the same.
Thanks,
