mce_gather

函数名称：Collect all global (w.r.t. this processor) status about this machine* check into our "mce" struct so that we can use it later to assess* the severity of the problem as we read per-bank specific details.

函数原型：static inline void mce_gather_info(struct mce *m, struct pt_regs *regs)

返回类型：void

参数：

类型	参数	名称
struct mce *	m
struct pt_regs *	regs

436

Do initial initialization of a struct mce

438

Machine Check Global Status MSR 等于MSR access wrappers used for error injection

439

如果regs则

444

如果Machine Check Global Status MSR 按位与start ip valid 按位或p points to correct instruction 的值则

445

Instruction Pointer when the error happened 等于ip

446

Code segment 等于cs

453

如果v8086_mode(regs)则Code segment 或等于3

457

如果rip_msr则Instruction Pointer when the error happened 等于MSR access wrappers used for error injection

名称	描述
machine_check_poll	Poll 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_check	The 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
