Misaka (ToaruOS 2.0)

Misaka is the "next-generation" (x86-64, SMP) kernel for ToaruOS.

This repository contains most of the same content as the upstream repository, including the userspace applications, libraries, and toolchain scripts. The bootloaders are not included - grub should work.

Note that Misaka is still considered a work in progress. While most of the OS is functioning, third-party ports are not ready, SMP support is still very unstable, and network support is unimplemented.

Completed Work

• The Toaru kernel has been ported to x86-64.
• Considerable changes have been made to make the kernel more portable to other architectures.
• Userspace fixes have been implemented to run on the new kernel.
• Some drivers have been ported (AC'97, serial, vmware mouse)
• SMP is functioning but highly unstable, the GUI can be run successfully and multiple graphical demos can run in parallel before eventual crashes.

Roadmap

• Kernel locking needs to be audited and SMP stability needs to be fixed. This will likely be a time-consuming process as these faults are difficult to debug.
• Some subsystems are being rewritten from scratch, such as the network stack.
• Third-party ports have not been made/tested yet; current plan is to have everything from the 1.10.x package series available again for x86-64.
• aarch64 and riscv64 ports are on the long-term roadmap.
• All of this will eventually be merged upstream.

Building

git clone https://github.com/toaruos/misaka
cd misaka
git submodule update --init kuroko
docker pull toaruos/build-tools:1.99.x
docker run -v `pwd`:/root/misaka -w /root/misaka -e LANG=C.UTF-8 -t toaruos/build-tools:1.99.x util/build-in-docker.sh

Running

qemu-system-x86_64 -kernel misaka-kernel -initrd ramdisk.tar -append "root=/dev/ram0 start=live-session migrate" -enable-kvm -m 1G

Add -smp 2 if you want to test with multiple cores. Up to 32 cores are "supported" at the moment.
