Intel Kabylake Will Still Require Firmware Blobs
Beginning with Skylake and Broxton hardware, Intel began requiring firmware blobs as part of their open-source graphics driver stack. This binary firmware is continuing forward with the next-generation Kabylake processors.
With the in-development Linux 4.5 kernel there is the initial Kabylake support, but that support will be further polished over the next few kernel cycles. Published today was the GuC loading support for Kabylake, The GuC engine is for workload scheduling on parallel graphics engines and is what necessitated the firmware introduction with Skylake and Broxton. So it's not entirely a surprise that there's going to be firmware blobs for Kabylake, it would have been more surprising if they would have dropped it after just one generation.
