A kernel targeting the ARM Cortex-A7 CPU used by the Raspberry Pi 2 B with the end goal of hosting Doom and only Doom.
Makefile is broken, use build.sh and run.sh. Requires the ARM GCC cross compiler and qemu to run.
Qemu supports outputting serial output to stdout, so we use UART for printk() and get output in the terminal.
this is a pain in the ass to get building right so good luck lol
I know this probably isn't realistic in any kind of reasonable timeframe but w/e, it's the journey not the desination
