'feat_inital_context_switching' Fix GDT and CS reload See merge request teachos/kernel!5
2025-03-28gdt: fix reload of GDTFelix Morgner8-29/+39
The core problems were/are the following: - The flags of the segments were not entirely correct. Please recheck them against the spec! - The GDT pointer did not contain the address of the first (null) GTD entry, but the address of the stl::vector containing the GDT entries. - The far pointer must consist of: - the address to jump to - the byte index into the GDT for the desired segement descriptor to be loaded into CS. - The type of the "dummy" function we jump to was wrong (it's a function, we should declare it as such). - We cannot enable interrupts right now, since we die with a triple fault. This is caused by some initia fault which seems to lead to a general protection fault, which then triple faults since we cannot find the IDT. Some FIXMEs have been added to the code. Please look at them carefully and compare things against the specs.
