函数名称:dtsc() - returns the current TSC without ordering constraints* rdtsc() returns the result of RDTSC as a 64-bit integer

函数原型:static __always_inline unsigned long long rdtsc(void)

返回类型:unsigned long long

参数:

203  Using 64-bit values saves one instruction clearing the high half of low (val, low, high)
205  asm volatile
207  返回:EAX_EDX_VAL(val, low, high)

machine_check_pollPoll for corrected events or events that happened before reset.* Those are just logged through /dev/mcelog.* This is executed in standard interrupt context.* Note: spec recommends to panic for fatal unsignalled* errors here
do_machine_checkThe actual machine check handler. This only handles real* exceptions when something got corrupted coming in through int 18.* This is executed in NMI context not subject to normal locking rules. This* implies that most kernel services cannot be safely used
