"To the dismay of open-source fans, NVIDIA is tightening the belt so to speak around their GPU hardware: with Maxwell and future hardware, certain aspects of the NVIDIA graphics processor chip will only be available to the "Falcon" (a.k.a. "FUC") firmware images that have been signed by NVIDIA. While this will throw a wrench at Nouveau's open-source effort, NVIDIA at least informed Nouveau and are jointly working towards an adequate solution."
