KVM: selftests: Use canonical $(ARCH) paths for KVM selftests directories

2024-12-18T22:15:04+00:00

Use the kernel's canonical $(ARCH) paths instead of the raw target triple for KVM selftests directories. KVM selftests are quite nearly the only place in the entire kernel that using the target triple for directories, tools/testing/selftests/drivers/s390x being the lone holdout. Using the kernel's preferred nomenclature eliminates the minor, but annoying, friction of having to translate to KVM's selftests directories, e.g. for pattern matching, opening files, running selftests, etc. Opportunsitically delete file comments that reference the full path of the file, as they are obviously prone to becoming stale, and serve no known purpose.

selftests: kvm: s390: Add kvm_s390_sie_block definition for userspace tests

2024-08-19T07:51:15+00:00

Subsequent tests do require direct manipulation of the SIE control block. This commit introduces the SIE control block definition for use within the selftests. There are already definitions of this within the kernel. This differs in two ways. * This is the first definition of this in userspace. * In the context of the selftests this does not require atomicity for the flags. With the userspace definition of the SIE block layout now being present we can reuse the values in other tests where applicable.

KVM: s390: selftests: Add selftest for single-stepping

2023-08-28T09:24:20+00:00

Test different variations of single-stepping into interrupts: - SVC and PGM interrupts; - Interrupts generated by ISKE; - Interrupts generated by instructions emulated by KVM; - Interrupts generated by instructions emulated by userspace.
