Supposed Code for Navi GPU in AMD Linux Driver Busted

Not too long ago there were some claims around the Internet that the next generation of GPUs from AMD, based on the Navi architecture, already had code in the AMD Linux driver. The folks at Phoronix, who specialize in covering Linux, have also taken a look at the code and explained the reference to GFX10 is not Navi, or any specific GPU for that matter. The code itself first appeared back in July and is related to AMD's open-source GPU debugger, UMR, and is to supply it with arbitrary new GPU information. It is not a part of the debugger but a demo file for testing the debugger.

As further evidence this is not Navi, or anything else, GFX10 is also identified as "SUPER_SECRET," uses the address 0x12345670, and the demo code calls it "Fakerizo," which is a play on the words fake and Carrizo, an AMD APU. While it does make sense for Navi to also bear the GFX10 identifier, as Vega is GFX9, this is not it.

Navi is currently expected to arrive in H2 2018 though, so it may only be months before it appears in the Linux driver code. With luck though, this driver support will come in time for the launch, thanks to AMDGPU DC having been merged and the AMD Vulkan driver having been open-sourced.
