Fork from https://github.com/ashleygwilliams/x86-kernel, v1 @ https://github.com/ThePerkinrex/PercOS

PercOS v2

PercOS v2 is the successor to PercOS, a python3 virtual machine that just simulated a UNIX-like OS.

PercOS v2 is barebones x86-64 bit kernel written in rust.

For now it has a module to write to the VGA buffer implementing the print! and println! macros as well as a macro for panicking. It implements simple paging & very rough shell.

To set up the environment, you'll need vagrant, lldb (The rust-lldb version), make, rust & a lot of things.

To set up vagrant follow the instructions on the vagrant docs

To setup the lldb debugger, run the script setup.sh, you may need to run chmod +x setup.sh to be able to run the script.

If you're not on osx, you may need to install qemu & edit th makefile to make the qemu variable point to your installation As well you can use gdb on linux, but follow this instructions to use it: https://os.phil-opp.com/set-up-gdb/

To use the environment, everything goes through the makefile.

To start, start the vagrant vm with make up
To stop the vm: make halt
To build everything: make iso
To run it with qemu: make run To start lldb & qemu: make lldb To start lldb & qemu connecting to qemu from the start: make lldb-d To start qemu and make it wait for a debugger to connect use: make debug
