AMD's Alex Deucher has sent in the first Radeon DRM driver pull request for early Linux 3.10 kernel
changes to be merged into the drm-next repository.
The Linux 3.10 merge window will likely open up in about two weeks time and so AMD is beginning to line up their driver changes they would like as part of the Direct Rendering Manager updates. Alex's first 3.10 pull request was submitted Tuesday afternoon with this email
For end-users, the major Radeon driver changes for Linux 3.10 are UVD video decoding support
and RadeonSI tiling support
. The Unified Video Decoder support is the kernel-side bits while the Gallium3D changes are already living in Mesa for its next release in a few months time. New Radeon firmware is also needed for this hardware-accelerated video playback support over VDPAU. The tiling support for AMD Radeon HD 7000 series hardware also requires user-space updates too for the RadeonSI Gallium3D driver, libdrm, and the xf86-video-ati DDX.
Aside from the two major features, the rest is basically bug-fixes. Alex does note though in his mailing list message that there might be a later pull request with some "new things" that they have been developing internally at the company. Better power management? Performance optimizations? We'll have to wait and see.
