Vastly Improved Raspberry Pi Performance With Wayland

[wraggster]

While Wayland/Weston 1.1 brought support (http://tech.slashdot.org/story/13/04/16/1527240/wayland-11-released-now-with-raspberry-pi-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 (http://www.raspberrypi.org/archives/4053) 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 (http://fooishbar.org/tell-me-about/wayland-on-raspberry-pi/). Developer Pekka Paalanen also provided additional technical details (http://ppaalanen.blogspot.fi/2013/05/weston-on-raspberry-pi-accelerated.html) 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."
