# State Of Development

This file will serve as a living journal of what I'm working on with regards
|
|
to the project, so I can step away from it and come back to it without having
|
|
to figure out what I was doing from commit messages alone.

## 2026-10-08: TSS Descriptor Weirdness
|
|
|
|
Loading the TSS selector into the Task Register was causing endless general
|
|
protection faults, which seemed... odd. Turns out, I was performing some bad
|
|
encoding when generating the TSS descriptor in the GDT, as well as loading
|
|
the bytes in the wrong order. Fixing the descriptor generation code and
|
|
swapping the bytes was enough to fix the GPFs. Now, the kernel makes it to
|
|
usermode, before triple faulting due to page faults. This is probably because
|
|
I put the stack in a bogus, unmapped address.
|
|
|
|
The next issue to work on will be paging and memory allocation. I need to
|
|
allocate memory to load and start the initial process, and to do that, I
|
|
need to finalize how I want process page mappings to be stored. It has to
|
|
align with Gila's capability model. After that, I can write some basic
|
|
syscalls, and compile a very minimal binary to test running processes. |
