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 }
Expand description
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]
Expand description
The full 64-bit canonical forms of the stack pointers (RSP) for privilege levels 0-2.
interrupt_stack_table: [VirtAddr; 7]
Expand description
The full 64-bit canonical forms of the interrupt stack table (IST) pointers.
iomap_base: u16
Expand description
The 16-bit offset to the I/O permission bit map from the 64-bit TSS base.
