Todos

• Explain how memory-mapping registers work.

• SpinLocks.

• Physical page allocation.

• Learn in-depth about constant evaluation.

• Understand what are pulse interrupts (edge triggered).

• Understand what the array_macro crate does, such that we can initialize an array even if the elements don't have the Copy trait implemented.

• Read about atomics and memory ordering in detail.

• Read : https://amjad.alsharafi.dev/en/posts/operating-system/spinlocks/ and https://www.reddit.com/r/rust/comments/18be8fg/blog_operating_systems_spinlocks/.

Scope of improvements

• Support the multiboot protocol.

• Take a look at the spinning_top SpinLock implementation.

• Use a Slab allocator instead of the Buddy allocator.

• Support multi-threading.
