Daniel Mack 364dbdf3b6 video: add driver for PXA3xx 2D graphics accelerator This adds a driver for the the 2D graphics accelerator found on PXA3xx processors. Only resource mapping, interrupt handling and a simple ioctl handler is done by the kernel part, the rest of the logic is implemented in DirectFB userspace. Graphic applications greatly benefit for line drawing, blend, and rectangle and triangle filling operations. Benchmarks done on a PXA303 using the df_dok benchmarking tool follow, where the value in square brackets show the CPU usage during that test.
