Hello,
I am starting to look at using the OpenGL drivers for the SGX on the DM8148, specifically looking at the Qt demos. I want to use the SGX for rendering but do not want the output to go to the LCD or DVI. I'd like it to go to a memory buffer I have allocated. When the rendering is complete to that buffer, I would DMA it to our FPGA for blending with other video streams in the FPGA. Our FPGA already performs blending of an OSD buffer with video streams so I only need to use the SGX for rendering and my buffer to be DMA'd to the FPGA would be the "frame buffer".
How can I change the configuration to output to my "frame buffer"? Is this a change to the Qt graphics plugin or somewhere else? Any information on how to get started would be greatly appreciated.
Thanks!
