#[repr(C)]
pub struct SnpPageInfo {

}

Structure describing the pages being read during SNP ID block measurement. Each structure is hashed with the previous structures digest to create a final measurement

Fields

digest_current: [u8; 48]

Set to the value of the previous page’s launch digest

contents: [u8; 48]

Hash of page contents, if measured

length: u16

Size of the SnpPageInfo struct

page_type: SnpPageType

type of page being measured, described by SnpPageType

imi_page_bit: u8

imi_page_bit must match IMI_PAGE flag

lower_vmpl_permissions: u32

All lower VMPL permissions are denied for SNP

gpa: u64

The guest physical address at which this page data should be loaded; it must be aligned to a page size boundary.
