KVM: s390: selftests: Add regression tests for PFCR subfunctions

2024-11-11T12:15:44Z

Check if the PFCR query reported in userspace coincides with the kernel reported function list. Right now we don't mask the functions in the kernel so they have to be the same.

KVM: s390: selftests: Fix whitespace confusion in ucontrol test

2024-11-11T12:07:04Z

Checkpatch thinks that we're doing a multiplication but we're obviously not. Fix 4 instances where we adhered to wrong checkpatch advice.

KVM: s390: selftests: Verify reject memory region operations for ucontrol VMs

2024-11-11T12:06:07Z

Add a test case verifying KVM_SET_USER_MEMORY_REGION and KVM_SET_USER_MEMORY_REGION2 cannot be executed on ucontrol VMs. Executing this test case on not patched kernels will cause a null pointer dereference in the host kernel.

KVM: s390: selftests: Add uc_skey VM test case

Add a test case manipulating s390 storage keys from within the ucontrol VM. Storage key instruction (ISKE, SSKE and RRBE) intercepts and Keyless-subset facility are disabled on first use, where the skeys are setup by KVM in non ucontrol VMs. Signed-off-by: Christoph Schlameuss Link: https://lore.kernel.org/r/20241108091620.289406-1-schlameuss@linux.ibm.com Acked-by: Janosch Frank [frankja@linux.ibm.com: Fixed patch prefix] Signed-off-by: Janosch Frank Message-ID: <20241108091620.289406-1-schlameuss@linux.ibm.com>

KVM: s390: selftests: Add uc_map_unmap VM test case

2024-11-11T12:04:36Z

Add a test case verifying basic running and interaction of ucontrol VMs. Fill the segment and page tables for allocated memory and map memory on first access. * uc_map_unmap Store and load data to mapped and unmapped memory and use pic segment translation handling to map memory on access.

KVM: s390: selftests: Add regression tests for PLO subfunctions

2024-10-07T08:53:55Z

Extend the existing regression test framework for s390x CPU subfunctions to include tests for the Perform Locked Operation (PLO) subfunction functions. PLO was introduced in the very first 64-bit machine generation. Hence it is assumed PLO is always installed in the Z Arch. The test procedure follows the established pattern.

Extend the existing regression test framework for s390x CPU subfunctions to include tests for the PRNO (Perform Random Number Operation), KDSA (Compute Digital Signature Authentication) and KMA (Cipher Message with Authentication) crypto functions. The test procedure follows the established pattern: 1. Obtain KVM_S390_VM_CPU_MACHINE_SUBFUNC attribute for the VM. 2. Execute PRNO, KDSA and KMA instructions. 3. Compare KVM-reported results with direct instruction execution results.
