Now that we created a new TSS, we need a way to tell the CPU that it should use it. Unfortunately this is a bit cumbersome, since the TSS uses the segmentation system (for historical reasons). Instead of loading the table directly, we need to add a new segment descriptor to the [Global Descriptor Table] \(GDT). Then we can load our TSS invoking the [`ltr` instruction] with the respective GDT index. (This is the reason why we named our module `gdt`.)

### The Global Descriptor Table
The Global Descriptor Table (GDT) is a relict that was used for [memory segmentation] before paging became the de facto standard. It is still needed in 64-bit mode for various things such as kernel/user mode configuration or TSS loading.
