While we have covered most of the DRM 4.13 changes individually in the past, they largely come down to:
- DRM synchronization object support in core DRM.
- Initial Cannonlake Intel support as well as Intel Coffeelake support. There's also work on GuC/bost buffer-based communication and other low-level driver improvements.
- Many Vega fixes for AMDGPU as well as initial Raven Ridge support (the forthcoming APU with Vega + Zen combination).
- AMDGPU also has KIQ support for compute rings, SR-IOV improvements, and more.
- The Nouveau DRM driver has initial HDMI 3D / stereoscopic support.
- Various improvements to the Freedreno and VC4 DRM drivers.
- The pl111 display controller code was finally merged and should excite some ARM Linux folks.
- Continued DRM core work around atomic mode-setting and helpers.
The more comprehensive list of DRM changes for Linux 4.13 can be found via this pull request. As expected, no AMDGPU DC/DAL support nor any magical Maxwell/Pascal re-clocking for Nouveau DRM driver. While GCN 1.0/1.1 AMDGPU selection has improved in Linux 4.13 with some new module parameters, they still are defaulting as well to Radeon DRM.
