At the end of February, Broadcom announced the release of full documentation for the VideoCore IV graphics core, and a complete source release of the graphics stack for the BCM21553 cellphone chip. To celebrate, we offered a $10k prize to the first person to port this codebase to the BCM2835 application processor that sits at the heart of the Raspberry Pi, and to get Quake 3 (which already runs on the Pi) running on the newly open ARM driver, rather on the closed-source VPU driver. Our hope was that the ported driver would be a helpful reference for anyone working on a Mesa/Gallium3D driver for VideoCore IV.
I’m delighted to say that we have a winner. Simon Hall is a longtime Pi hacker, who also produced the first ARMv6-accelerated copies-and-fills library back in 2012 and wrote the DMA kernel module that we integrate in our Raspbian releases. The prize couldn’t have gone to a more fitting recipient.
So, without further ado, here are Simon’s instructions for getting the driver up and running….
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
