Hi, Kassey, I've been looking at the driver some to understand how you're using the hardware. One quick question: > The driver is based on soc-camera + videobuf2 frame > work, and only USERPTR is supported. Since you're limited to contiguous DMA (does the PXA910 even support scatter/gather mode?), USERPTR is going to be very limiting. Is the application mapping I/O memory elsewhere in the system with the expectation of having the video frames go directly there? Could you tell me how that works? I'd like to understand the use case here. FWIW, I believe that videobuf2 would support the MMAP mode with no additional effort on your part; any reason why you haven't enabled that?
