Non Preemptive Kernel.

[sajay@temenos.com]

Hi,

I have a doubt in the Non Preemptive Kernel. In the case of a Non Preemptive Kernel, the Kernel Control Path cannot be preempted unless it relinquishes the CPU Voluntarily. In this scenario, supposing a Timer interrupt occurs, how does the timer Interrupt handler find out that a Kernel Control Path is running and hence the process shouldn't be preempted. Or is this handled by the schedule() function.

Cheers,
