New submitter nekohayo writes "While Wayland/Weston 1.1 brought support to the Raspberry Pi merely a month ago, work has recently been done to bring true hardware-accelerated compositing capabilities to the RPi's graphics stack using Weston. The Raspberry Pi foundation has made an announcement about the work that has been done with Collabora to make this happen. X.org/Wayland developer Daniel Stone has written a blog post about this, including a video demonstrating the improved reactivity and performance. Developer Pekka Paalanen also provided additional technical details about the implementation."
Rather than using the OpenGL ES hardware, the new compositor implementation uses the SoC's 2D scaler/compositing hardware which offers "a scaling throughput of 500 megapixels per second and blending throughput of 1 gigapixel per second. It runs independently of the OpenGL ES hardware, so we can continue to render 3D graphics at the full, very fast rate, even while compositing."
