This patch series introduces a set of regression tests for various s390x CPU subfunctions in KVM. The tests ensure that the KVM implementation accurately reflects the behavior of actual CPU instructions for these subfunctions.
The series adds tests for a total of 15 instructions across five patches, covering a range of operations including sorting, compression, and various cryptographic functions. Each patch follows a consistent testing pattern:
- Obtain the KVM_S390_VM_CPU_MACHINE_SUBFUNC attribute for the VM.
- Execute the relevant asm instructions.
- Compare KVM-reported results with direct instruction execution results.
Testing has been performed on s390x hardware with KVM support. All tests pass successfully, verifying the correct implementation of these subfunctions in KVM.
I've picked this up but seem to have missed adding it to 6.12 since I have a lot going on.
It will be in 6.13 though.
