函数名称：pology_phys_to_logical_die - Map a physical die id to logical* Returns logical die id or -1 if not found

函数原型：int topology_phys_to_logical_die(unsigned int die_id, unsigned int cur_cpu)

返回类型：int

参数：

类型参数名称
unsigned intdie_id
unsigned intcur_cpu
310  proc_id等于phys_proc_id
312  遍历可用CPU(cpu)
313  c等于cpu_data(cpu)
315  如果initialized且cpu_die_id恒等于die_id且Physical processor id: 恒等于proc_id则返回:logical_die_id
319  返回:负1
