Implementations

impl MemoryVtlType

pub const VTL0: MemoryVtlType

This memory is for VTL0.

pub const VTL2_RAM: MemoryVtlType

This memory is used by VTL2 as regular ram.

pub const VTL2_CONFIG: MemoryVtlType

This memory holds VTL2 config data, which is marked as reserved to the kernel.

pub const VTL2_SIDECAR_IMAGE: MemoryVtlType

This memory is used by the VTL2 sidecar as it’s image, and is marked as reserved to the kernel.

pub const VTL2_SIDECAR_NODE: MemoryVtlType

This memory is used by the VTL2 sidecar as node memory, and is marked as reserved to the kernel.

pub const VTL0_MMIO: MemoryVtlType

This range is mmio for VTL0.

pub const VTL2_MMIO: MemoryVtlType

This range is mmio for VTL2.

pub const VTL2_RESERVED: MemoryVtlType

This memory holds VTL2 data which should be preserved by the kernel and usermode. Today, this is only used for SNP: VMSA, CPUID pages, and secrets pages.

pub const VTL2_GPA_POOL: MemoryVtlType

This memory is used by VTL2 usermode as a persisted GPA page pool. This memory is part of VTL2’s address space, not VTL0’s. It is marked as reserved to the kernel.

pub const VTL2_TDX_PAGE_TABLES: MemoryVtlType

This memory is used by VTL2 for TDX AP startup page tables, and is marked as reserved to the kernel.

pub const VTL2_BOOTSHIM_LOG_BUFFER: MemoryVtlType

This memory is used by VTL2 to store in-memory bootshim logs. It is marked as reserved to the kernel.

pub const VTL2_PERSISTED_STATE_HEADER: MemoryVtlType

This memory is used by VTL2 to store a persisted state header. This memory is marked as reserved to the kernel.

pub const VTL2_PERSISTED_STATE_PROTOBUF: MemoryVtlType

This memory is used by VTL2 to store the persisted protobuf payload. This memory is marked as reserved to the kernel.

impl MemoryVtlType

pub fn ram(&self) -> bool

Returns true if this range is a ram type.

pub fn vtl2(&self) -> bool

Returns true if this range is used by VTL2.

Trait Implementations

impl Clone for MemoryVtlType

fn clone(&self) -> MemoryVtlType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MemoryVtlType

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DefaultEncoding for MemoryVtlType

type Encoding = TableEncoder

The encoding to use for the serialization.

impl DescribeTable for MemoryVtlType

const DESCRIPTION: MessageDescription<'static>

The protobuf message description for this type.

impl Hash for MemoryVtlType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for MemoryVtlType

fn cmp(&self, other: &MemoryVtlType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MemoryVtlType

fn eq(&self, other: &MemoryVtlType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for MemoryVtlType

fn partial_cmp(&self, other: &MemoryVtlType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
