2D Rendering On X11 Remains Barely Faster Than CPU Rendering
In addition to being the organizer of XDC2016, Martin Peres also participated in several presentations at this week's conference in Helsinki. One of these pesentations by Martin was concerning 2D X.Org acceleration.
Martin basically presented on that rendering 2D on a modern X.Org Server is barely faster than CPU rendering, unless compositing. While being barely faster, it consumes more power than CPU-only rendering. But the good news is that more and more software is moving away from X-based rendering.
With the next GTK+ release there will be the GTK Scene Kit, Qt5 already has changed its renderer, and other projects are moving over to purely CPU-based rendering or GPU rendering with projects like Servo's WebRender, Google's Skia, and the new Intel FastUIDraw project.

AMD's DAL Was Just Presented At XDC2016, Still Not Clear When It Will Be Mainlined
Harry Wentland of AMD just presented at the XDC2016 conference about DAL, the big Display Abstraction Layer code-base, which many AMD Linux users have been waiting to see merged in order to have Polaris audio support and this is one of the stepping stones for seeing FreeSync/Adaptive-Sync and other modern display capabilities.
We have been covering DAL for months since AMD open-sourced it and since then they've been trying to clean it up, remove some redundancies compared to what core DRM offers, etc. DAL is a big piece of the puzzle that's left for getting mainlined so the AMDGPU open-source kernel driver can be closer to feature parity with the closed-source driver and what's provided on Windows.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
