An AArch64 hobbyist OS for the Raspberry Pi 3 B+

Yet another hobby x86 UNIX-like operating system written in C and C++. Features a dynamically linked userspace, an in-house c standard library, and more! And yes, it runs DOOM.

Running x86-16 or x86-32 code from x86-64 UEFI; _very experimental_ • mirror of https://gitlab.com/tkchia/biefircate • developer notes at https://gitlab.com/tkchia/biefircate/-/blob/main/doc/NOTES.asciidoc
