pepperOS: "will never be done"

Trying the kernel

First install the dependencies: sudo apt install xorriso make qemu-system

Then, to compile the kernel and make an ISO image file: make build-iso To run it with QEMU, make run

TODO

The basics that I'm targeting are:

• Fix terminal driver (backspace issues, scrolling) OR add Flanterm or equivalent
• Implement paging / see what Limine does at boot with memory management
• Implement tasks, and task switching
• Load an executable
• Scheduler (round-robin using the PIT timer interrupt)
• Filesystem (TAR for read-only initfs, then maybe read-write using FAT12/16/32
• Getting to userspace (syscalls)
• Porting musl libc or equivalent

In the future, maybe?

• SMP support
• Parsing the ACPI tables and using them for something
• Replacing the PIT timer with APIC

Thanks

PepperOS wouldn't be possible without the following freely-licensed software:

• the Limine portable bootloader
• Marco Paland's freestanding printf implementation
• the ZAP PSF console fonts

...and without these amazing resources:
