Here's A Fresh Ubuntu Kernel Spin With The Latest AMDGPU PowerPlay Support
As I had to spin a fresh kernel anyways to conduct the AMDGPU year-end benchmarks for various articles, I've uploaded the kernel in case any other R9 285 or R9 Fury owners out there want to try out the latest open-source support.
I built the AMDGPU PowerPlay kernel this morning from the amdgpu-powerplay Git branch since the PowerPlay support currently isn't queued up for Linux 4.5 in amd-next-4.5-wip or elsewhere, let alone DRM-Next. The kernel is based on Linux 4.4 and the latest PowerPlay patches are as of four days ago in the amdgpu-powerplay branch.
If you are not familiar with the AMDGPU PowerPlay/re-clocking situation, see AMDGPU With PowerPlay Compared To AMD's Catalyst Linux Driver. Stay tuned for my various Linux graphics end-of-the-year tests in the days ahead on Phoronix.
You can download this x86_64 kernel build as linux-image-4.4.0-rc3-amdgpu-pp-phx-xmas_4.4.0-rc3-amdgpu-pp-phx-xmas-1_amd64.deb.
