Struct acpi::PhysicalMapping

pub struct PhysicalMapping<H, T> where
    H: AcpiHandler,  { /* fields omitted */ }

Describes a physical mapping created by AcpiHandler::map_physical_region and unmapped by AcpiHandler::unmap_physical_region. The region mapped must be at least size_of::<T>() bytes, but may be bigger.

Implementations

impl<H, T> PhysicalMapping<H, T> where
    H: AcpiHandler, 

pub unsafe fn new(
    physical_start: usize,
    virtual_start: NonNull<T>,
    region_length: usize,
    mapped_length: usize,
    handler: H
) -> PhysicalMapping<H, T>

Construct a new PhysicalMapping. mapped_length may differ from region_length if padding is added for alignment.

Safety

This function must only be called by an AcpiHandler of type H to make sure that it’s safe to unmap the mapping.

• virtual_start must be a valid pointer.
• region_length must be equal to or larger than size_of::<T>().
• handler must be the same AcpiHandler that created the mapping.
