It is used by the operating system kernel for task management. Specifically, the following information is … 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 instruction and acts in a manner similar to other segment register loads. The task register has two parts: a portion visible and … 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 … 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. See the 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 LDT).
