RGBA/ARGB LVDS output from i.MX6

Hi. I'm working with the i.MX6 with Yocto 1.5 "Dora" BSP.


In my setup the i.MX6 is required to output GUI as video with alpha-per-pixel values. The GUI is accelerated using OpenGL and the output I use is the LVDS. This LVDS output is connecte to an FPGA. The FPGA is responsible for blending of this GUI with incoming video. After blending (alpha-per-pixel) the FPGA conveys the blended result to screen.

My question is whether it is possible to output GUI with alpha values (some RGBA/ARGB/etc format) from the LVDS output? if this kind of output (video with alpha-per-pixel) is not available, is it possible to have some way/trick to enable it?


I'll appreciate any insights in general and any suggestions regrading possible solution (like changes in IPU/LVDS drivers, manipulation in GPU etc).


Thank you.
