But if users want it, we can always add a shadow-buffer and advertise it as RGB332 or alike. Otherwise, they have to use fbdev as usual, which sounds reasonable to me. > - 16-bit RGB555 (16-bit littleendian words with R=14:10, G=9:5, B=4:0) DRM_FORMAT_XRGB1555 > - 16-bit RGB565 (16-bit littleendian words with R=15:11, G=10:5, B=4:0) DRM_FORMAT_RGB565 > - 24-bit RGB888 in littleendian order (first byte in memory is B, > second is G, third is R) DRM_FORMAT_RGB888 > - 32-bit ARGB8888 (first byte in memory is B, second G, third R, fourth > unused in the framebuffer proper) DRM_FORMAT_ARGB8888 > - 32-bit RGB10:10:10 (I *believe* 32-bit littleendian words with > R=29:20, G=19:10, B=9:0) DRM_FORMAT_XRGB2101010 Thanks for the hints, I will add these to patch #5.
