Although I'm not sure EINVAL is the best choice here. Maybe ENOSYS?

We return -EINVAL everywhere else where we don't support a giving config, e.g. lack of dpll, unsupported plane scaling, pixel format mismatch of the primary plane (since we don't yet have per-gen lists of supported formats for the primary plane) and so on. So I've figured -EINVAL is good enough until we have something better with the test mode for atomic modesets. -Daniel
