# IndigoOS
|
|
|
|
IndigoOS (name likely to change) will be a unix-like operating system for x86-64 computers. I'm hoping to impliment many things a modern operating system would have, including a desktop enviornment, pre-emptive multithreading, ASLR, and memory protection. I'd also like to port games such as DOOM.
|
|
|
|
This project is in it's infancy. However, I'm making quick progress. I'll only commit major changes to keep the commit history clean.
|
|
|
|
## Cleaning list
|
|
- [ ] clean RSDP v1 vs v2+ ugly unison code
|
|
- [ ] clean static paging code
|
|
- [ ] fallback to best compatable video mode if not found
|
|
- [ ] find out when and why checksum of binary vs debug binary stripped is occationally diffrent (maybe linker script?)
|
|
|
|
|
|
## debugging
|
|
- [x] get debugging into into a seperate elf for GDB
|
|
- [ ] md5sum of striped binary is the same as one built without debugging info
|
|
_Almost_ always, there was one time when it wasn't. Can't seem to reproduce. Check linker sizes and included sections.
|
|
|
|
## bootloader
|
|
- [x] make USB bootable as floppy
|
|
- [ ] make USB bootable as harddisk
|
|
- [x] detect native resolution
|
|
- [x] set VESA video to native resolution
|
|
- [ ] fallback to best compatable video mode if not found
|
|
- [x] record video mode info for kernel
|
|
- [x] setup temporary page tabels
|
|
- [x] get memory map
|
|
- [x] load sectors into 0x100000
|
|
- [x] boot into kernel long mode
|
|
|
|
## Kernel
|
|
|
|
### Memory
|
|
- [x] static page mapping
|
|
- [ ] dynamic page allocation - 3/24/21, almost done, will likely finish soon.
|
|
- [ ] remap paging to higher/more available physical address
|
|
- [ ] remap kernel to higher virtual address
|
|
- [ ] create a written map of virtual shared/kernel addresses for documentation
|
|
|
|
### ACPI
|
|
- [x] find, check, and parse RSDP
|
|
- [x] find, check, and parse RSDT or XSDT
|
|
|
|
### multicpu
|
|
- [ ] boot cpus
|
|
- [ ] parse MDST
