Struct ostd::mm::DmaCoherent

source ·
pub struct DmaCoherent { /* private fields */ }
Expand description

A coherent (or consistent) DMA mapping, which guarantees that the device and the CPU can access the data in parallel.

The mapping will be destroyed automatically when the object is dropped.

Implementations§

source§

impl DmaCoherent

source

pub fn map( vm_segment: Segment, is_cache_coherent: bool, ) -> Result<Self, DmaError>

Creates a coherent DMA mapping backed by vm_segment.

The is_cache_coherent argument specifies whether the target device that the DMA mapping is prepared for can access the main memory in a CPU cache coherent way or not.

The method fails if any part of the given vm_segment already belongs to a DMA mapping.

source§

impl<'a> DmaCoherent

source

pub fn reader(&'a self) -> VmReader<'a>

Methods from Deref<Target = Segment>§

source

pub fn range(&self, range: Range<usize>) -> Self
