[−][src]Struct x86_64::structures::gdt::GlobalDescriptorTable
A 64-bit mode global descriptor table (GDT).
In 64-bit mode, segmentation is not supported. The GDT is used nonetheless, for example for switching between user and kernel mode or for loading a TSS.
The GDT has a fixed size of 8 entries, trying to add more entries will panic.
Methods
impl GlobalDescriptorTable[src]
pub fn new() -> GlobalDescriptorTable[src]
Creates an empty GDT.
pub fn add_entry(&mut self, entry: Descriptor) -> SegmentSelector[src]
Adds the given segment descriptor to the GDT, returning the segment selector.
Panics if the GDT has no free entries left.
pub fn load(&'static self)[src]
Loads the GDT in the CPU using the lgdt instruction.
