The Linux 4.15 kernel is looking to be a very exciting update for AMDGPU DRM driver users.

AMDGPU for Linux 4.15 is already very exciting as it should finally have the DC display code and enabled by default for RX Vega users. On top of that there's also been other AMDGPU Direct Rendering Manager work including an increased fragment size and a variety of other changes.

Alex Deucher has now submitted another feature pull request targeting DRM-Next for Linux 4.15. This latest pull is also heavy on new features.

These latest changes include a new clock query interface for upcoming Raven Ridge APUs, a new FENCE_TO_HANDLE ioctl, UVD video encode ring support for Polaris, transparent huge-page DMA support, deadlock fixes, compute pipe LRU tweaks, PowerPlay clean-ups and fixes, and various other fixes and code improvements.

DRM subsystem maintainer David Airlie has already pulled these latest changes into DRM-Next.
