Radeon DRM Changes For The Linux 3.20 Kernel
The new AMDGPU kernel driver for supporting the R9 285 / GCN 1.2 GPUs and newer has yet to publicly appear. However, for the Radeon DRM driver there's still an exciting number of improvements for this next kernel version. The Radeon DRM changes for Linux 3.20 include:
- Indirect draw support for the Radeon HD 5000/6000 series (Evergreen and Northern Islands GPUs).
- SMC fan control support for Radeon HD 7000 / Rx 200 series graphics processors (SI/CI).
- Manual fan control support for the GCN GPUs (SI/CI).
- DisplayPort audio support.
- Many code clean-ups.
Separate from the Radeon DRM pull is also the AMDKFD HSA driver updates for Linux 3.20, which include getting ready for the upcoming Carrizo APUs, albeit also blocked by the lack of the AMDGPU kernel driver's availability. The full list of changes for this Radeon DRM-Next pull request can be found on the DRI-devel list.
