| H A D | dma.rst | 1 USB DMA
4 In Linux 2.5 kernels (and later), USB device drivers have additional control
6 in the kernel usb programming guide (kerneldoc, from the source code).
11 The big picture is that USB drivers can continue to ignore most DMA issues,
12 though they still must provide DMA-ready buffers (see
13 Documentation/core-api/dma-api-howto.rst). That's how they've worked through
14 the 2.4 (and earlier) kernels, or they can now be DMA-aware.
16 DMA-aware usb drivers:
18 - New calls enable DMA-aware drivers, letting them allocate dma buffers and
19 manage dma mappings for existing dma-ready buffers (see below).
