MiyarOS v0.2(under progress) Core Infrastructure. This development cycle focused on building the core foundation of MiyarOS. The kernel now detects and parses the Multiboot memory map, implements a bitmap-based Physical Memory Manager with 4 KiB frame allocation, introduces a dynamic kernel heap (“kmalloc”/“kfree”), and enables paging with the first version of the Virtual Memory Manager for page mapping and unmapping.Memory protection has also been improved by marking kernel pages as read-only and leaving the null page unmapped to catch invalid pointer accesses. A dedicated page fault handler and centralized kernel panic system were added, providing detailed crash information for easier debugging. Finally, the shell was refactored to support command and argument parsing, creating a cleaner and more scalable foundation for future features.

Hey guys, I have built “MiyarOS” which is a small open source hobby operating system for x86 that boots with GRUB and follows the Multiboot specification. The kernel is written in C and x86 Assembly, and it currently provides a text-mode boot experience with basic hardware setup, a keyboard-driven shell, VGA output, and serial debugging. This is only the start, I wanna scale this later into a fully fledged OS. Hope that day comes, truly.

I just built a very simple cli bot with 3 functions in C.
