Hi, If my task P is currently executing in the CPU and if an interrupt occurs during that time, I understand that there will be a context switch and the interrupt service routine will be executed in the Kernel's context. Once the interrupt service routine is over, will my task P gets to the CPU (Assuming P has its time slice yet to finish) or will the scheduler take control?
