Full rewrite of the P2M DMA Engine to support scatter gather and take advantage of some of the features of the hardware. This includes using repeat DMA operations and line-mode transfers (for copying OSG and video display buffers). What isn't working: For some reason, descriptor mode is not working. I've implemented a psuedo version (still has one-interrupt per DMA operation), but we would get huge improvements if we could hand off a ring of descriptors to the P2M and get back one interrupt when it was done with all of them. Documentation is very vague on this, and even the ODM example code half attempts to get it right, but comments it out of the driver because it just doesn't work *sigh* Converts all v4l2 to dma-sg. So long slow dma-contiguous, but hello more interrupts :( Signed-off-by: Ben Collins <bcollins@bluecherry.net> |
