Implementations

impl<'a, I: Iterator<Item = MemoryRange>> AddressSpaceManagerBuilder<'a, I>

pub fn new( manager: &'a mut AddressSpaceManager, vtl2_ram: &'a [MemoryEntry], bootshim_used: MemoryRange, persisted_state_region: MemoryRange, vtl2_config: I, ) -> AddressSpaceManagerBuilder<'a, I>

Create a new builder to initialize an AddressSpaceManager.

vtl2_ram is the list of ram ranges for VTL2, which must be sorted.

bootshim_used is the range used by the bootshim, but may be reclaimed as ram by the kernel.

persisted_state_region is the range used to store the persisted state header described by [loader_defs::shim::PersistedStateHeader] and corresponding protbuf payload.

Other ranges described by other methods must lie within bootshim_used.

pub fn with_reserved_range(self, reserved_range: MemoryRange) -> Self

A reserved range reported as type [MemoryVtlType::VTL2_RESERVED].

pub fn with_sidecar_image(self, sidecar_image: MemoryRange) -> Self

The sidecar image, reported as type [MemoryVtlType::VTL2_SIDECAR_IMAGE].

pub fn with_page_tables(self, page_tables: MemoryRange) -> Self

Pagetables that are reported as type [MemoryVtlType::VTL2_TDX_PAGE_TABLES].

pub fn with_log_buffer(self, log_buffer: MemoryRange) -> Self

Log buffer that is reported as type [MemoryVtlType::VTL2_BOOTSHIM_LOG_BUFFER].

pub fn with_pool_range(self, pool_range: MemoryRange) -> Self

Existing VTL2 GPA pool ranges, reported as type [MemoryVtlType::VTL2_GPA_POOL].

pub fn init(self) -> Result<&'a mut AddressSpaceManager, Error>

Consume the builder and initialize the address space manager.
