| 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. |
