The AMDGPU DRM code for Linux 4.9 is already queued in DRM-Next with virtual display support and other features as well as experimental GCN Southern Islands support while today another feature pull request was submitted to DRM-Next with more Radeon/AMDGPU changes.

This final feature pull for the Radeon/AMDGPU code planned for Linux 4.9 brings mostly PowerPlay changes. Alex Deucher of AMD noted in today's pull request, "Last set of radeon and amdgpu changes for 4.9. This is mostly just the powerplay cleanup for dGPUs. Beyond that, just misc code cleanups and bug fixes."

The pull request with the numerous PowerPlay changes can be found via this pull request. With this being the final PR for AMDGPU Linux 4.9 features, it also confirms there will be no DAL (Display Abstraction Layer) code for AMDGPU in Linux 4.9... DAL is needed for supporting HDMI audio with Polaris, FreeSync, and other display-related features to bring it to parity with the closed-source AMD driver and other modern display features.
