apio	35b7194fb7	Move initialization into an init() function returning Result<void> so we can use TRY ... And remove a lot of testing code as well.	2022-11-20 17:56:07 +01:00

apio	caf6d1563c	Kernel: Add a heap memory allocator ... This is the first time I've actually dropped liballoc in favor of writing my own implementation. Usually, malloc() and such looked so complicated that I preferred to let a nice external library do the job. But I've decided to try writing my own allocator, and now we have heap memory without any 3rd party code!	2022-11-20 15:15:26 +01:00
apio	d96cb73995	Rename physical "pages" to "frames" ... AFAIK, this is the proper naming scheme. "Pages" are virtual, and "frames" physical.	2022-11-19 22:27:08 +01:00
