There's still a lot to do:
-
refactor udev to list all available GPUs -
refactor DrmBackend to use the outputs of all GPUs -
make Atomic Mode Setting work properly on multiple GPUs (it doesn't on my secondary GPU) -
create a new OpenGLBackend that contains multiple other backends -
enable EglGbmBackend to copy buffers from other GPUs -
enable EglStreamBackend to copy buffers from other GPUs -
enable hotplugging of GPUs?
