This is the last part of the UVA-OS class (CS4414/CS6456).

Students: see quests-lab5.md

The OS now includes a full libc (newlib) and miniature libSDL (for abstracting input/output events), atop which we port additional applications, including a music player, a blockchain miner, and DOOM (1993, itrunsdoom). To enable easy file exchanges between our OS and PC/Mac machines, we also bring up the SD card driver and port FAT32 filesystem support. We implement a desktop environment, comprising a simple window manager and an input dispatcher; as such multiple apps can be rendered on the screen concurrently. Eventually, we bring up all four CPU cores to unleash full power of the Raspberry Pi 3.

This OS introduces virtual memory and user/kernel separation. It provides syscalls and can run one or multiple "Mario" applications concurrently in userspace.
