A state-of-the-art Linux distro for RISC laptops that I could get my hands on (atm only ARM Chromebooks).
ARM based single board computers that try to suck less. Roughly the same form factor and capabilities of the Raspberry Pi. I'm told that you can just drop Armbian onto a card and boot it up.
Broadcom opensourced the GPU drivers for the RaspberryPi under a three-clause BSD license. The code is fully functional, hasn't been reverse engineered, and can be compiled and used imediately on the RasPi.
Unicorn is a super-CPU emulator which handles multiple common processor core architectures, from x86 to Arm. Based on QEMU, written in pure C for speed and portability. Has multiple API bindings for different languages. Does just-in-time (JIT) translation of opcodes. Designed from the ground up to be thread-safe.
