My Favorite Features/Changes Of The Linux 4.5 Kernel

With Linux 4.5 looking like it will release next weekend, here’s a look at my favorite features/changes of Linux 4.5

– AMDGPU PowerPlay, AMDGPU PP, AMDGPU re-clocking, or “finally how I can get good performance out of my new Tonga~Fiji graphics cards on open-source.” Whatever you want to call it, the AMDGPU driver finally having experimental PowerPlay support is critical for allowing newer GCN 1.2+ graphics cards like the R9 285 “Tonga” and R9 Fury “Fiji” graphics cards to finally perform well. Up until now when using AMDGPU with a discrete GPU, the cards have been limited to their (low) boot frequencies and thus meant very poor performance. Now the future is looking much brighter with AMDGPU PowerPlay support especially as the new Catalyst Linux stack and Vulkan driver require AMDGPU.
