interrupt latency


Hi,
My system is S3C2410 @203MHZ. with Linux OS. What is interrupt latency,
when GPIO interrupt happens? I guess it depends on Linux. How about
RTLinux system? How long RTLinux disable interrupt in worst case?

Any comment is appreciate.

For RTLinux, the worst case interrupt plus scheduling is sub-20 microsecond range on most platforms, according to the vendor.
