nmi_panic

函数名称：A variant of panic() called from NMI context. We return if we've already* panicked on this CPU. If another CPU already panicked, loop in* nmi_panic_self_stop() which can provide architecture dependent code such* as saving register state for crash dump.

函数原型：void nmi_panic(struct pt_regs *regs, const char *msg)

返回类型：void

参数：

类型	参数	名称
struct pt_regs *	regs
const char *	msg

cpu等于These macros fold the SMP functionality into a single CPU system()

129

old_cpu等于atomic_cmpxchg( & panic_cpu, PANIC_CPU_INVALID, cpu)

131

如果old_cpu恒等于PANIC_CPU_INVALID则panic - halt the system*@fmt: The text string to print* Display a message, then perform cleanups.* This function never returns.

133

否则如果old_cpu不等于cpu则Stop ourselves in NMI context if another CPU has already panicked. Arch code* may override this to prepare for crash dumping, e.g. save regs info.
