是否所有核心都把林丹 into入碎块?
原标题:Does Linux drop into the kernel on all cores?

对于一个多分计算机,运行的LC 2.6.x,当一个校对系统发出信号时会发生什么情况? 它是否只落在read子上,或者投向所有核心的摇篮(如果这是一个新问题的话)。

这种行为(无论正确)在一般接受中断时是否相同? 如果不是的话,分歧是什么?

最佳回答

只穿透镜子。 氯氟烃的所有排期都是在表面的微粒度上进行的。 至于打断,它们被转往一个核心,即每个特定硬件活动只中断一个处理器。 然后,可以人工将断断断线分配给具体核心。 在<代码>/proc/irq/IRQ-NUMBER/smp_affinity上用面罩进行。 您可以看到,CPU接收哪些硬件在<代码>/proc/interrupts上中断。
