Hi,
Am porting the Linux kernel to a new architecture (the 370 instruction set). I noticed that the timer interrupt does very little. The question is this: how does scheduling work if/when there are no other interrupts occuring? e.g. have two numeric processes running, neither is making system calls, neither is swapping. etc.
The esa/390's are mainframes; there are no serial ports, no video or video interrupts, no regular i/o or bus interrupts; nothing else is ticking in any sort of quasi-periodic manner. What should I do, make the timer interrupt do a schedule every ten ticks or something?
