selftests: KVM: Free the GIC FD when cleaning up in arch_timer

2022-04-27T12:41:07Z

[ Upstream commit 21db83846683d3987666505a3ec38f367708199a ] In order to correctly destroy a VM, all references to the VM must be freed. The arch_timer selftest creates a VGIC for the guest, which itself holds a reference to the VM. Close the GIC FD when cleaning up a VM.

kvm: selftests: aarch64: fix the failure check in kvm_set_gsi_routing_irqchip_check

2022-04-13T17:27:13Z

[ Upstream commit 5b7898648f02083012900e48d063e51ccbdad165 ] kvm_set_gsi_routing_irqchip_check(expect_failure=true) is used to check the error code returned by the kernel when trying to setup an invalid gsi routing table. The ioctl fails if "pin >= KVM_IRQCHIP_NUM_PINS", so kvm_set_gsi_routing_irqchip_check() should test the error only when "intid >= KVM_IRQCHIP_NUM_PINS+32". The issue is that the test check is "intid >= KVM_IRQCHIP_NUM_PINS", so for a case like "intid = KVM_IRQCHIP_NUM_PINS" the test wrongly assumes that the kernel will return an error. Fix this by using the right check.

kvm: selftests: aarch64: pass vgic_irq guest args as a pointer

2022-04-13T17:27:13Z

[ Upstream commit 11024a7a0ac26dd31ddfa0f6590e158bdf9ab858 ] The guest in vgic_irq gets its arguments in a struct. This struct used to fit nicely in a single register so vcpu_args_set() was able to pass it by value by setting x0 with it. Unfortunately, this args struct grew after some commits and some guest args became random (specically kvm_supports_irqfd). Fix this by passing the guest args as a pointer (after allocating some guest memory for it).

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: arm64: selftests: get-reg-list: Add pauth configuration

2022-01-04T13:39:55Z

The get-reg-list test ignores the Pointer Authentication features, which is a shame now that we have relatively common HW with this feature. Define two new configurations (with and without PMU) that exercise the KVM capabilities.

KVM: selftests: aarch64: Add test for restoring active IRQs

2021-12-28T19:25:05Z

Add a test that restores multiple IRQs in active state, it does it by writing into ISACTIVER from the guest and using KVM ioctls. This test tries to emulate what would happen during a live migration: restore active IRQs.
