| Name | Describe |
|---|---|
| cpu_init | pu_init() initializes state that is per-CPU. Some data is already* initialized (naturally) in the bootstrap process, such as the GDT* and IDT. We reload them nevertheless, this function acts as a* 'CPU state barrier', nothing should get across. |
| native_load_tr_desc | The LTR instruction marks the TSS GDT entry as busy. On 64-bit, the GDT is* a read-only remapping. To prevent a page fault, the GDT is switched to the* original writeable version when needed. |
