Authors: MarioS271
Modules§
- gdt 🔒
- Global Descriptor Table (GDT): owns the kernel segment descriptors and the TSS selector, and loads them into the CPU.
- idt 🔒
- Interrupt Descriptor Table (IDT): maps every interrupt vector to its handler and loads the table into the CPU.
- tss 🔒
- Task State Segment (TSS): owns the Interrupt Stack Table and its dedicated stacks for exceptions that need a known-good stack.
