Intel Skylake & Broxton Graphics Processors To Start Mandating Binary Blobs

Intel has often been portrayed as the golden child within the Linux/BSD community and by those desiring a fully-free system without tainting their kernel with binary blobs while wanting a fully-supported open-source driver. The Intel Linux graphics driver over the years hasn't required any firmware blobs for acceleration, compared to AMD's open-source driver having many binary-only microcode files and Nouveau [freedesktop.org] also needing blobs — including firmware files that NVIDIA still hasn't released [phoronix.com] for their latest GPUs. However, beginning with Intel Skylake and Broxton CPUs, their open-source driver will now too require closed-source firmware [phoronix.com]. The required "GuC" and "DMC" firmware files are for handling the new hardware's display microcontroller and workload scheduling engine. These firmware files are explicitly closed-source licensed and forbid any reverse-engineering. What choices are left for those wanting a fully-free, de-blobbed system while having a usable desktop?

Time to revive the Open Graphics Project [wikipedia.org] ..?

(those binary blobs may contain root kits)
