KVM: s390: selftests: Add ucontrol gis routing test

2025-01-07T15:36:11Z

Add a selftests for the interrupt routing configuration when using ucontrol VMs. Calling the test may trigger a null pointer dereferences on kernels not containing the fixes in this patch series.

KVM: s390: selftests: Add ucontrol flic attr selftests

2025-01-07T15:36:10Z

Add some superficial selftests for the floating interrupt controller when using ucontrol VMs. These tests are intended to cover very basic calls only. Some of the calls may trigger null pointer dereferences on kernels not containing the fixes in this patch series.

KVM: arm64: Fix set_id_regs selftest for ASIDBITS becoming unwritable

In commit 03c7527e97f7 ("KVM: arm64: Do not allow ID_AA64MMFR0_EL1.ASIDbits to be overridden") we made that bitfield in the ID registers unwritable however the change neglected to make the corresponding update to set_id_regs resulting in it failing: ok 56 ID_AA64MMFR0_EL1_BIGEND ==== Test Assertion Failure ==== aarch64/set_id_regs.c:434: masks[idx] & ftr_bits[j].mask == ftr_bits[j].mask pid=5566 tid=5566 errno=22 - Invalid argument 1 0x00000000004034a7: test_vm_ftr_id_regs at set_id_regs.c:434 2 0x0000000000401b53: main at set_id_regs.c:684 3 0x0000ffff8e6b7543: ?? ??:0 4 0x0000ffff8e6b7617: ?? ??:0 5 0x0000000000401e6f: _start at ??:? not ok 8 selftests: kvm: set_id_regs # exit=254 Remove ID_AA64MMFR1_EL1.ASIDBITS from the set of bitfields we test for writeability.

Merge tag 'kvmarm-6.13' of https://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

2024-11-14T12:05:36Z

KVM/arm64 changes for 6.13, part #1 - Support for stage-1 permission indirection (FEAT_S1PIE) and permission overlays (FEAT_S1POE), including nested virt + the emulated page table walker - Introduce PSCI SYSTEM_OFF2 support to KVM + client driver. This call was introduced in PSCIv1.3 as a mechanism to request hibernation, similar to the S4 state in ACPI - Explicitly trap + hide FEAT_MPAM (QoS controls) from KVM guests. As part of it, introduce trivial initialization of the host's MPAM context so KVM can use the corresponding traps - PMU support under nested virtualization, honoring the guest hypervisor's trap configuration and event filtering when running a nested guest - Fixes to vgic ITS serialization where stale device/interrupt table entries are not zeroed when the mapping is invalidated by the VM - Avoid emulated MMIO completion if userspace has requested synchronous external abort injection - Various fixes and cleanups affecting pKVM, vCPU initialization, and selftests
