| Description: |
| Read/write interface that reports the vector of SEV-SNP |
| firmware vulnerability mitigations already verified by the |
| firmware. Writing a vector value requests the firmware to |
| VERIFY the corresponding mitigation bit(s). |
| |
| The list of supported mitigations and the meaning of each |
| vector bit are both platform- and bug-specific and are |
| published as part of the AMD Security Bulletin. |
