PIT

I quickly wrote a simple PIT (Programmable Interval Timer) driver, so that I have a basic sleep function.
It isn’t really useful at the moment and not thread safe, but as it was very simple I thought why not?

APIC

I realized that MADT I/O APIC overrides also override the flags of entries, so I am using these now unless it’s overridden by the user.

Road map

As I have now a simple keyboard driver, I want to work on something new. Some things I am considering:

• Multitasking
• Filesystems
• ELF loading
• PCI
• USB

All of this topics are completely new to me, so I will pick the one that looks the most simple and probably fail anyway.
