selftests: KVM: Create helper for making SMCCC calls

2022-05-03T20:30:20Z

The PSCI and PV stolen time tests both need to make SMCCC calls within the guest. Create a helper for making SMCCC calls and rework the existing tests to use the library function.

Merge tag 'kvmarm-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

2022-03-18T16:43:24Z

KVM/arm64 updates for 5.18 - Proper emulation of the OSLock feature of the debug architecture - Scalibility improvements for the MMU lock when dirty logging is on - New VMID allocator, which will eventually help with SVA in VMs - Better support for PMUs in heterogenous systems - PSCI 1.1 support, enabling support for SYSTEM_RESET2 - Implement CONFIG_DEBUG_LIST at EL2 - Make CONFIG_ARM64_ERRATUM_2077057 default y - Reduce the overhead of VM exit when no interrupt is pending - Remove traces of 32bit ARM host support from the documentation - Updated vgic selftests - Various cleanups, doc updates and spelling fixes

KVM: selftests: aarch64: Skip tests if we can't create a vgic-v3

2022-02-25T13:02:28Z

The arch_timer and vgic_irq kselftests assume that they can create a vgic-v3, using the library function vgic_v3_setup() which aborts with a test failure if it is not possible to do so. Since vgic-v3 can only be instantiated on systems where the host has GICv3 this leads to false positives on older systems where that is not the case. Fix this by changing vgic_v3_setup() to return an error if the vgic can't be instantiated and have the callers skip if this happens. We could also exit flagging a skip in vgic_v3_setup() but this would prevent future test cases conditionally deciding which GIC to use or generally doing more complex output.

kvm: selftests: aarch64: use a tighter assert in vgic_poke_irq()

2022-02-08T15:18:58Z

vgic_poke_irq() checks that the attr argument passed to the vgic device ioctl is sane. Make this check tighter by moving it to after the last attr update.
