dev(sched): Improvements and work in progress fixes.
what?
- The main algorithm got improved for real time tasks, and SMP usage.
- The SMP usage was present before, I just reintroduced it after
realizing that it won't scale well from what I have right now.
- Also removed weird implementations quirks from previous sketch.
- Such as the core 0 being reserved for the boot core.
- Also moved FS init code after IDT initalization.
- To avoid weird FS format behavior.
- Wrap HPET signature in a macro.
next?
- Work on the HAL's userspace transition mechanism.
