coreOS

What even is this?

Honestly, don't know. It is a fun project tho. I'll see how far I take stuff with this.

To do list (in order of when I'm probably going to make stuff, give or take):

• VGA driver (currently under development)
• Serial driver
• <stdio.h> input functions (mostly done, still needing scanf however)
• PS2 mouse driver
• Preemptive scheduler
• Terminal system (already begun, mostly only needs to be adapted to run as a process rather than as part of the kernel)
• First sorta proper GUI
• SATA driver
• Filesystem
• <string>, <iostream>, and all other IO headers
• Support for multiple cores
• USB drivers
• Remaining C standard library
• Remaining C++ standard library (this will take forever)
• x86_64 long mode (ugh)

That's a lot of to dos, what's already done?

• It boots
• Paging, heap allocation
• Interrupt service routines
• PS2 keyboard driver
• VGA text mode
• Basic kernel error reporting (mostly only for page faults currently)
• PIT which will probably only be used for the scheduler
• Kernel wait functions which put the CPU in a lower power state (C1)
• 12 TTYs

• Meaty Skeleton - I used this as a base structure while getting started
• osdev.org - Got a lot of useful information while making this from there
