# 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
|
|
|
|
### 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
|
