2025-09-24	KVM: arm64: selftests: Cope with arch silliness in EL2 selftest	Oliver Upton	1	-2/+15
	Implementations without FEAT_FGT aren't required to trap the entire ID register space when HCR_EL2.TID3 is set. This is a terrible idea, as the hypervisor may need to advertise the absence of a feature to the VM using a negative value in a signed field, FEAT_E2H0 being a great example of this. Cope with uncooperative implementations in the EL2 selftest by accepting a zero value when FEAT_FGT is absent and otherwise only tolerating the expected nonzero value.

2025-09-24	KVM: arm64: selftests: Add basic test for running in VHE EL2	Oliver Upton	1	-0/+58
	Add an embarrassingly simple selftest for sanity checking KVM's VHE EL2 and test that the ID register bits are consistent with HCR_EL2.E2H being RES1. Signed-off-by: Oliver Upton <oliver.upton@linux.dev> Signed-off-by: Marc Zyngier <maz@kernel.org>
