DISCLAIMER: Most of this code is very old and even more of it is built with lacking knowledge of the underlying systems. If reading this ends up giving you an aneurysm, feel free to open an issue about it, but I am not responsible for any brain damage you might end up getting xD

Lighthouse OS

Lighthouse OS is yet another operating system that is built cuz it can be built. It constits of a kernel called Aniva and a userspace that I've very creatively called LightEnv

yey, ANOTHER stinking kernel. As if the world needed one lmao

Finished shit

• Boots (miracle)
• Runs shit (another miracle)
• Memory is managed
• Two implementations for in-kernel heaps
• Logging system
• Driver framework
• Dynamic driver loading/unloading/linking
• Filesystems that go brrrr
• insane assembly (fr ong)
• Working ring 3
• libc implementation
• Our own custom userspace libraries (yay)
• A kernel terminal driver (kterm)
• Quite a lot actualy, more than I thought...

I am so insane at naming shit, holy fuck

TODOS:

[ ] Fully implement FAT32 (File creation/deletion, reading AND writing, lfn, ect.) [ ] Also make sure cramfs is on the same level as FAT (obv we can't write or create files, but u get me) [ ] Implement actual system time (why don't we have this yet) [ ] Implement signals via upi [ ] Make the scheduler fast again or sm [ ] Fix the USB hid drivers [ ] Fix the EHCI driver for real hardware [ ] Fully implement xhci [ ] Implement usbblk driver [ ] NET drivers: I don't even have to say it [ ] Implement power management and diagnostics (I want to know how much power devices are using, I think that would be so cool) [ ] Fix this OS on AMD cpus lol. It currently throws an Illegal instruction exception somewhere during processor init... [ ] Fully implement the lwnd window manager [ ] Video drivers to support a lil fast windowmanager [ ] Drivers kill me

Build & Run

Before you can build/run anything, you need to build and install the custom toolchain for this kernel. This is done by running the build-cross.sh script which will download and extract the sources and then prompt the user a few times to get shit up and running. This process can take a while, but there might be prompts that need your attention, so leaving it completely alone is not recommended.

Build

For building this project there is really only one option (the makefile needs to either be edited or removed lol): In the ./project folder, there is an executable python script called x.py which you can run from the project root (That would become ./project/x.py or something) and opens a cute dialog window for easy tooling =) (Don't look at the python code please)

Run

If you want to try this shit out, make sure you have QEMU installed to PATH on your device. Running this has two main ways of doing it (Option 2 is better in my unbiased oppinion):

1. Using the Makefile: run make iso to create a .iso file and make run to launch QEMU with the grub bootloader into our kernel
2. Using light-loader: The preferred way to run this shit is by using the bootloader that is designed for the OS. Advanced instructions are found in the light-loader git repo, but it comes down to copying the kernel and ramdisk into the folder of the bootloader and running the bootloader
