Enum MemoryAllocationMode

pub enum MemoryAllocationMode {
    Host,
    Vtl2 {
        memory_size: Option<u64>,
        mmio_size: Option<u64>,
    },
}

The memory allocation mode provided by the host. This determines how OpenHCL will allocate memory for itself from the partition memory map.

Variants

Host

Use the host provided memory topology, and use VTL2_PROTECTABLE entries as VTL2 ram. This is the default if no openhcl/memory-allocation-property mode is provided by the host.

Vtl2

Allow VTL2 to select its own ranges from the address space to use for memory, with a size provided by the host.

Fields

memory_size: Option<u64>

The number of bytes VTL2 should allocate for memory for itself. Encoded as openhcl/memory-size in device tree.

mmio_size: Option<u64>

The number of bytes VTL2 should allocate for mmio for itself. Encoded as openhcl/mmio-size in device tree.

Trait Implementations

impl Clone for MemoryAllocationMode

fn clone(&self) -> MemoryAllocationMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryAllocationMode

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

Formats the value using the given formatter.

impl PartialEq for MemoryAllocationMode

fn eq(&self, other: &MemoryAllocationMode) -> 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.
