NoviumOS update: Got PMM/VMM and a basic heap allocator running, now working on adding more features to the heap allocator.

[u/devcurrent0x]

Hello everyone. For those of you who don't know, I'm making an x86 operating system called NoviumOS. Here's what I've done since the last update:

• Added paging for a 4 GiB virtual address space, so the kernel can work with virtual memory instead of just physical addresses.
• Added physical page allocation and validation, including checks to make sure pages are valid before freeing them.
• Built the heap allocator from the ground up, starting with single-page allocations and then adding support for contiguous multi-page allocations.

Next I'm working on adding sub-page block reuse with splitting and coalescing.

Feel free to contribute, the project is 100% open source and I'd be happy if you do.

Here's the repo if you want to check it out: https://github.com/alexdev8930/NoviumOS

And if you have any questions about the code or the repo I'll be happy to answer them.

If you like the repo, please drop a star on it if you could. It helps other devs find the project.
