This series primarily introduces SEV-SNP test for the kernel selftest framework. It tests boot, ioctl, pre fault, and fallocate in various combinations to exercise both positive and negative launch flow paths.
Patch 1 - Adds a wrapper for the ioctl calls that decouple ioctl and asserts, which enables the use of negative test cases. No functional change intended. Patch 2 - Extend the sev smoke tests to use the SNP specific ioctl calls and sets up memory to boot a SNP guest VM Patch 3 - Adds SNP to shutdown testing Patch 4, 5 - Tests the ioctl path for SEV, SEV-ES and SNP Patch 6 - Adds support for SNP in KVM_SEV_INIT2 tests Patch 7,8,9 - Enable Prefault tests for SEV, SEV-ES and SNP
There are three separate series here:
- Smoke test support for SNP
- Negative tests for SEV+
- Prefault tests for SEV+
#3 likely has a dependency on #1, and probably on #2 as well (for style if nothing else). But that's really just an argument for focuing on #1 first, and the moving onto the others once that's ready to go.
Based on your feedback on the rest of this patchset, this makes sense to me. I will first prep for the changes for patchset #1 and once we lock that down I can introduce patchset #2 and #3 based on that design.
Thank you again for your feedback! Pratik
