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

#[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.
