GO-OSe

GO-OSe is an experiment in low level microprocessor programming using the Go programming language . Goose implements a basic x86 asm bootstrap which drops into kernel.Kmain() in Go, and provides rudimentary text io.

Why?

Because I wanted to see if it was possible. Turns out it is, but not without making sacrifices. Go's lack of pointer arithmetic means you remain fairly dependant on asm to do things that would otherwise be trivial in C.

Because we're creating our own environment for Go, a lot of it's features must be implemented manually using asm, or at the very least defined as noop to allow compilation.

tldr: It's fun, but not worth it.

Building

Goose requires gccgo, and a cross compiler toolchain may have to be built if the host os is 64-bit. More info on that here: http://wiki.osdev.org/GCC_Cross-Compiler

If compiling from source, remember to add go to gcc's --enable-languages config option.
