holy crap there was so much debugging that had to happen. so the memory allocator pretty much fell apart. I realised that (with the help of gemini) that having a buddy allocator for physical frames was irrelevant, considering that physical memory could be remapped however necessary. as far as I know, there is no need for continuous physical memory except for legacy hardware, which i guess can be its own function later then. so I just made a bitmap allocator. physical memory is extremely irrelevant, we don’t care about anything other than the virtual memory it’s paired to. now I can finally start work on a bitmap display somehow.
