Struct DmaRequest 

pub struct DmaRequest {
    pub channel: DmaChannel,
    pub direction: DmaDirection,
}

An asserted DMA request (DRQ), without a memory address or transfer count.

The host’s DMA controller owns address, count, page wrapping, masking and terminal-count behavior. This descriptor only reports the device’s request; it neither performs nor acknowledges a transfer.

Fields

channel: DmaChannel

DMA channel configured for this device.

direction: DmaDirection

Whether data flows into or out of the device.
