As a first test, the sync_regs from x86 has been adapted to s390x, and after a fix for KVM_CAP_MAX_VCPU_ID on s390x, the kvm_create_max_vcpus is now enabled here, too. Please note that the ucall() interface is not used yet - since s390x neither has PIO nor MMIO, this needs some more work first before it becomes usable (we likely should use a DIAG hypercall here, which is what the sync_reg test is currently using, too... I started working on that topic, but did not finish that work yet, so I decided to not include it yet). RFC -> v1: - Rebase, needed to add the first patch for vcpu_nested_state_get/set - Added patch to introduce VM_MODE_DEFAULT macro - Improved/cleaned up the code in processor.c - Added patch to fix KVM_CAP_MAX_VCPU_ID on s390x - Added patch to enable the kvm_create_max_vcpus on s390x and aarch64 Andrew Jones (1): kvm: selftests: aarch64: fix default vm mode Thomas Huth (8): KVM: selftests: Wrap vcpu_nested_state_get/set functions with x86 guard KVM: selftests: Guard struct kvm_vcpu_events with __KVM_HAVE_VCPU_EVENTS KVM: selftests: Introduce a VM_MODE_DEFAULT macro for the default bits KVM: selftests: Align memory region addresses to 1M on s390x KVM: selftests: Add processor code for s390x KVM: selftests: Add the sync_regs test for s390x KVM: s390: Do not report unusabled IDs via KVM_CAP_MAX_VCPU_ID KVM: selftests: Move kvm_create_max_vcpus test to generic code MAINTAINERS | 2 + arch/mips/kvm/mips.c | 3 + arch/powerpc/kvm/powerpc.c | 3 + arch/s390/kvm/kvm-s390.c | 1 + arch/x86/kvm/x86.c | 3 + tools/testing/selftests/kvm/Makefile | 7 +- .../testing/selftests/kvm/include/kvm_util.h | 10 + .../selftests/kvm/include/s390x/processor.h | 22 ++ .../kvm/{x86_64 => }/kvm_create_max_vcpus.c | 3 +- .../selftests/kvm/lib/aarch64/processor.c | 2 +- tools/testing/selftests/kvm/lib/kvm_util.c | 25 +- .../selftests/kvm/lib/s390x/processor.c | 286 ++++++++++++++++++ .../selftests/kvm/lib/x86_64/processor.c | 2 +- .../selftests/kvm/s390x/sync_regs_test.c | 151 +++++++++ virt/kvm/arm/arm.c | 3 + virt/kvm/kvm_main.c | 2 - 16 files changed, 514 insertions(+), 11 deletions(-) create mode 100644 tools/testing/selftests/kvm/include/s390x/processor.h rename tools/testing/selftests/kvm/{x86_64 => }/kvm_create_max_vcpus.c (93%) create mode 100644 tools/testing/selftests/kvm/lib/s390x/processor.c create mode 100644 tools/testing/selftests/kvm/s390x/sync_regs_test.c
