[][src]Struct x86_64::structures::tss::TaskStateSegment

#[repr(C, packed)]
pub struct TaskStateSegment { pub privilege_stack_table: [VirtAddr; 3], pub interrupt_stack_table: [VirtAddr; 7], pub iomap_base: u16, // some fields omitted }

In 64-bit mode the TSS holds information that is not directly related to the task-switch mechanism, but is used for finding kernel level stack if interrupts arrive while in kernel mode.

Fields

privilege_stack_table: [VirtAddr; 3]

The full 64-bit canonical forms of the stack pointers (RSP) for privilege levels 0-2.

interrupt_stack_table: [VirtAddr; 7]

The full 64-bit canonical forms of the interrupt stack table (IST) pointers.

iomap_base: u16

The 16-bit offset to the I/O permission bit map from the 64-bit TSS base.

Methods

impl TaskStateSegment[src]

pub const fn new() -> TaskStateSegment[src]

Creates a new TSS with zeroed privilege and interrupt stack table and a zero iomap_base.
