On 28 Mar, linas@linas.org spewed forth: :: :: 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? :: :: --linas ::
Hehe, now *there's* and undertaking! Running Linux on an IBM mainframe! Do you actually have access to a mainframe to test on? I'd be interested in know what type of progress you are making, although I don't think our CC admins would let me try it out.
