AMD "KERNCZ" Chipset Support Is Being Worked On For Linux

AMD KERNCZ is a new generation name for an AMD chipset / FCH (Fusion Controller Hub).

We haven't heard AMD talk about KERNCZ or see it mentioned elsewhere outside of Linux kernel enablement patches. Based upon current timing and these patches just appearing recently, I would guess that KERNCZ would be the chipset for next-generation AMD Zen processors. Back in March we saw AMD begin with public Linux/open-source enablement patches around Zen and its new CPU micro-architecture.

So far when it comes to AMD KERNCZ Linux patches there was device ID support posted yesterday, "The KERNCZ is new AMD SB/FCH generation name, like HUDSON2. We will adopt 0x790b as device ID since from this gereration." Going into Linux 4.1 already was KERNCZ GPIO support. There's also been a few other KERNCZ patches floating about.

Given the current state of Linux 4.1 development and the limited patches out there thus far, the KERNCZ Linux support will likely get ironed out around the Linux 4.2~4.3 kernel releases.
