Hi, I have some questions on linux scheduling. Linux kernel is non-preemptive in kernel mode ..right. Now it is executing in the kernel mode and a timer interrupt occurs ,Does is preempt ..I mean the timer interrupt is of utmost priority it has to get processed. Please can someone enlighten me about what will happen if the timer interrupt occurs when it is executing in kernel mode on behalf of some process.
