In case you missed it from last month, the AMDGPU feature work landed for Linux 4.6 in DRM-Next. There is a lot of audio work, GPU scheduler optimizations, GPUVM optimizations, initial GPU reset support, and various other improvements. See that aforelinked article for all of the details.
Not ready for Linux 4.6 is that massive AMD DAL driver rework for AMDGPU.
This latest Radeon/AMDGPU pull request is mostly centered on the newer AMDGPU kernel driver while there is a Radeon ACPI header update with this pull. In total this latest pull has just ten changes and shifts around just about 100 lines of code.
If you are curious about the fixes now queued up in DRM-Next for AMDGPU, see this Git pull and the pull request that outlines all of the changes.
