- Hi,
-
- I have a MVME 147 based system, working under OS9.
-
- I want to react on interrupts from a device as follows: the
- device driver sends a signal by receiving of a interrupt and the
- software should react by using the _ss_ssig() and intercept()
- routines.
-
- My question: how long does it tipically take from the moment, the
- interrupt is issued by the hardware to the moment,
- I execute the first statement in my function called with intercept() ?
- Is it 100 us, 1 ms, 10 ms ?
-
- Second question: having a process sleeping on a event ( ev_wait() )
- and another process sending this event. How long does it take till the
- first process continues execution ? Assume, that just these two processes
- are in memory (besides kernel, drivers for floppy, hard disk, a tsmon, all
- the stuff which you usually have -- but only these two user processes),
- both processes have the same priority.
-
- Thank you for your help,
- Franz
