[kvm-unit-tests PATCH 0/2] arm/arm64: Use 'max' cpu and gic types

[Andrew Jones]

The arm64 'max' CPU type enables all features, so it makes sense to use
it for testing to ensure we're testing the latest models. The 'max' GIC
is used to pick the latest GIC model by default which is better than
defaulting to gicv2 since it tests a later model and, when more
than 8 CPUs are configured, it'll actually work. We don't need to
convert 'max' to 'host' with KVM/HVF since 'max' is an alias for
'host' when those accelerators are enabled.

[kvm-unit-tests PATCH 1/2] arm/arm64: Use 'max' gic type

[Andrew Jones]

The 'max' GIC type has been supported for six years (Mar. 2018).
Ever since its introduction we've considered switching to it for the
default in the run scripts. Now, with commit 5dd20ec76ea6 ("runtime:
Update MAX_SMP probe"), we no longer always check and restrict
MAX_SMP, so we'd have better luck with configurations working by
default by finally doing the switch. Of course we also get the
benefits of testing more modern models by default and requiring less
command line modifications when converting TCG to KVM/HVF.

[kvm-unit-tests PATCH 2/2] arm64: Use 'max' cpu type

[Andrew Jones]

The 'max' GIC type has been supported for six years (Mar. 2018).
Ever since its introduction we've considered switching to it for the
default in the run scripts in order to test more modern models by
default. Let's finally do it!

(HVF's support for '-cpu max' is younger (only 2 years), but that
should also be old enough.)
