AMDGPU Driver Called For Pulling Into DRM-Next For Linux 4.2 Kernel

While it should come as no surprise, Alex Deucher of AMD tonight submitted the AMDGPU kernel driver code for pulling into DRM-Next so that it can land for the Linux 4.2 kernel merge window.

Alex sent in the AMDGPU DRM driver pull request with support for AMD's Tonga, Iceland, and Carrizo graphics hardware -- along with an experimental kernel build-time option to test this driver on other CI hardware. For the new hardware, all key functionality is supported from the display/mode-setting to graphics, compute, DMA, video encode/decode, and other features. However, for now this driver limits power management to the new Carrizo APUs.

This new AMDGPU kernel driver works in conjunction with the (currently branched) Libdrm, Mesa, and xf86-video-amdgpu user-space code for supporting all of AMD's latest and future hardware. More details via this pull request for DRM-Next. I'll be working on some AMDGPU Tonga benchmarks soon followed by Carrizo APUs, etc. Stay tuned as always to Phoronix for the latest Linux hardware benchmarks.
