Design / WIP notes

TODO

Paging manager
- Copy-on-write pages
- Better page-allocation model?
Allow for more than one IOAPIC in ACPI module
- The objects get created, but GSI lookup only uses the one at index 0
mark kernel memory pages global
Serial out based on circular/bip biffer and interrupts, not spinning on write_ready()
Split out more code into kutil for testing
AHCI / MSI interrupts on Vbox break?
FXSAVE to save XMM registers.
- optimization using #NM (0x7) to detect SSE usage
Clean up of process memory maps
Better stack tracer
Bootloader rewrite
- C++ and sharing library code for ELF, initrd, etc
- Parse initrd and pre-load certain ELF images, eg the process loader process?
- Do initial memory bootstrap?
Calling global ctors
Device Tree
- Actual serial driver
- Disk driver
  - File system
Multiprocessing
- Fast syscalls using syscall/sysret

Clean up build generator and its templates
- More robust objects to represent modules & targets to pass to templates
- Read project setup from a simple JSON/TOML/etc
- Better compartmentalizing when doing template inheritance
Move to LLD as sysroot linker
