Bifrost meets GNOME: Onward & upward to zero graphics blobs
In our last blog update for Panfrost, the free and open-source graphics driver for modern Mali GPUs, we announced initial support for the Bifrost architecture. We have since extended this support to all major features of OpenGL ES 2.0 and even some features of desktop OpenGL 2.1. With only free software, a Mali G31 chip can now run Wayland compositors with zero-copy graphics, including GNOME 3. We can run every scene in glmark2-es2, and 3D games like Neverball can be played. In addition, we can support hardware-accelerated video players mpv and Kodi. Screenshots above are from a Mali G31 board running Panfrost.
All of the above is included in upstream Mesa with no out-of-tree patches required, with the upcoming Bifrost support enabled via the PAN_MESA_DEBUG=bifrost environmental variable.

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. |
