...rivers it is not so clear if the right thing will happen. E.g., freedreno seems to support both BGR and RGB 10 bit formats as PIPE_BIND_DISPLAY_TARGET afaics, so i don't know if by luck the right thing would happen? Afaics EGL does the right thing wrt. channelmask matching of EGLConfigs to DRIconfigs, so we could probably implement dri_loader_get_cap(screen, DRI_LOADER_CAP_RGBA_ORDERING) == TRUE for the EGL loaders. But for GLX it is not so easy or quick. I looked if i could make the servers GLX send proper channelmask attributes and Mesa parsing them, but there aren't any GLX tags defi...

In case anyone's curious about 30bpp framebuffer support, here's the current status: Kernel: Ben and I have switched the code to using a 256-based LUT for Kepler+, and I've also written a patch to cause the addfb ioctl to use the proper format. You can pick this up at: https://github.com/skeggsb/linux/commits/linux-4.16 (note the branch!)
