Design / WIP notes

TODO

• 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
  • Syscalls

Build

• 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
