hi ! I currently work with a cio-das ISA card (P200, BH5 motherboard, rtl v1.1) , and I measured an interrupt latency of 5us (irq3). Is there a link between the latency and the number of the irq. And the responds time reach 10us when I move the mouse , or use the hdd (lower priority !?). Is there a solution to avoid that? (do you have the same values?) I read the discussion about jitter, but just deal with scheduler.
