It is used by the operating system kernel for task management. Specifically, the following information is stored in the TSS: Processor register stateI/O port permissionsInner-level stack … See more The TSS may reside anywhere in memory. A segment register called the task register (TR) holds a segment selector that points to a valid TSS segment descriptor which resides in the GDT (a TSS descriptor may not reside in the See more The TSS contains a 16-bit pointer to I/O port permissions bitmap for the current task. This bitmap, usually set up by the operating system when a task is started, specifies individual … See more The TSS contains 6 fields for specifying the new stack pointer when a privilege level change happens. The field SS0 contains the stack segment selector for CPL=0, and the field ESP0/RSP0 contains the new ESP/RSP value for CPL=0. When an interrupt happens in … See more The TR register is a 16-bit register which holds a segment selector for the TSS. It may be loaded through the LTR instruction. LTR is a privileged … See more The TSS may contain saved values of all the x86 registers. This is used for task switching. The operating system may load the TSS with the values of the registers that the new task needs and after executing a hardware task switch (such as with an IRET … See more This is a 16-bit selector which allows linking this TSS with the previous one. This is only used for hardware task switching.
