Linux 5.6 Graphics Changes Bring Open-Source NVIDIA Turing, AMD Pollock Enablement

The Direct Rendering Manager (DRM) kernel driver updates were sent in today for Linux 5.6 with plenty of fun features in tow.

Highlights of the open-source kernel graphics driver changes for Linux 5.6 consist of:

- Nouveau Turing GeForce RTX 2000 series support albeit required on binary firmware images not yet published by NVIDIA. Beyond that, still no re-clocking support so the performance is quite slow. TU10x GPUs are supported and not yet TU11x.

- Intel has continued improvements for Gen11 Ice Lake graphics as well as a lot of work for Gen12 Tiger Lake graphics bring-up. There is also Coffee Lake HDCP 2.2 support and various other changes.

- DMCUB support for Renoir, among other Renoir improvements.

- Initial AMD Pollock support.

- BACO power-savings support for Arcturus and this Bus-Active Chip Off support is also for run-time power management savings. GFXOFF support for Navi 10.

- AMDGPU HDCP 2.x support built off the earlier HDCP support.

- The bits for Vulkan Timeline Semaphore support with Vulkan 1.2 is now added to the synchronization object primitives.

- DisplayPort Multi-Stream Transport Display Stream Compression (DP MST DSC).

- DMA-BUF HEAPS support.

- The Freedreno MSM DRM driver now has Adreno 618 support.
