Struct DmaMappedBuffer 

Source 
pub struct DmaMappedBuffer {
    pub virt_addr: usize,
    pub dma_addr: u64,
    pub size: usize,
    pub coherency: DmaCoherency,

Expand description

A DMA-mapped buffer with coherency and direction tracking.

Fields§

§virt_addr: usize

Virtual address of the buffer.

§dma_addr: u64

Physical address for DMA (may differ from actual phys with IOMMU).

§size: usize

Buffer size in bytes.

§coherency: DmaCoherency

Coherency policy.

§direction: DmaDirection

Transfer direction.
