kernel::arch::x86_64::tables::tss

Struct Tss 

Source 
pub struct Tss {
    tss: Once<TaskStateSegment>,
    ist1: AlignedStack<8192>,
    ist2: AlignedStack<8192>,
    ist3: AlignedStack<8192>,
    ist4: AlignedStack<8192>,
}
Expand description

Owns the TaskStateSegment and its four IST stacks; must not move after Tss::init (the GDT descriptor points to it).

Implementations§

Source§

impl Tss

Source

pub const fn new() -> Self

Create a new, uninitialized Tss; call Tss::init to populate it.

Source

pub fn init(&self)

Build the TSS, wiring IST slots 0–3 to this instance’s four dedicated stacks.

Source

pub fn get(&self) -> &TaskStateSegment

Return a reference to the initialized TaskStateSegment.

§Panics

Panics if Tss::init has not been called yet.
