| |
Hi, all, I'm curious that if a network card interrupt happens at the same time as the kernel timer expires, what will happen?
It's said the kernel timer is guaranteed accurate. But if interrupts are not masked off, the network interrupt also should get response when a kernel timer expires. So I don't know who will preempt who.
Thanks for information!
