pub struct PageTableBuilder { /* private fields */ }

Implementations

impl PageTableBuilder

pub fn new(page_table_gpa: u64) -> Self

pub fn with_mapped_region(self, start_gpa: u64, size: u64) -> Self

pub fn with_local_map(self, start_va: u64, size: u64) -> Self

pub fn with_confidential_bit(self, bit_position: u32) -> Self

pub fn with_reset_vector(self, map_reset_vector: bool) -> Self

Map the reset vector at page 0xFFFFF with a single page.

pub fn build(self) -> Vec<u8>

Build a set of X64 page tables identity mapping the given region. size must be less than 512GB. This creates up to 3+N page tables: 1 PML4E and up to 2 PDPTE tables, and N page tables counted at 1 per GB of size, for 2MB mappings.
