@onlyshawn @kongoshuu This still doesn't implement all the changes of the Rev 1.58 spec, so report parsing will fail, for example if PAGE_SWAP_DISABLE is true. Please check out #174 |

Background
According to the latest version of the AMD SEV-SNP ABI specification (Document #56860, Rev. 1.58, May 2025), the Attestation Report data structure has been updated with two new fields to indicate mitigations enabled at launch.
This change aligns our implementation with the latest firmware specification, ensuring we can correctly parse and generate attestation reports that include these new fields.
The new fields are:
LAUNCH_MIT_VECTOR (offset 0x1F8)
CURRENT_MIT_VECTOR (offset 0x200)
