This patchset introduces SEV-SNP test to the kernel selftest framework. It also adds negative testing of SEV, ES and SNP VM types. Patch 1 - Extend the sev smoke tests to use the SNP specific ioctl calls and sets up memory to boot a SNP guest VM Patch 2 - Cleanup patch that decouples the ioctl calls from the sev selftest library with its test assert and status counterparts. No functional change introduced Patch 3 - Introduce ioctl test for SEV, ES Patch 4 - Introduce positive and negative ioctl test for SEV-SNP Patch 5 - Adds the X86_FEATURE_SEV_SNP vm type test for KVM_SEV_INIT2 Any feedback/review on the approach and design is highly appreciated!
