DMA Framework

The DMA Framework is a kernel extension that manages DMA (Direct Memory Access) hardware.

Device drivers use DMA to copy data quickly between memory locations, and between memory and peripherals. This section describes how to create a port of it for your phone hardware. The Device Driver Guide documentation describes how to use the DMA Framework from a device driver.

The DMA Framework provides a Platform Independent Layer. You must provide a Platform Specific Layer to implement the interface to the DMA Controller hardware on your phone.
