I"m *trying* to write a device driver for a custom ISA-Card.
The Hardware is very simple and produces an Interrupt
every 20e-06 seconds. So the Interrupt should be serviced
at least after 10e-06 seconds. After Browsing Kernel Code I
saw that there are done some things *before* the custom
Interrupt-Handler (set by request_irq) is called. My Question now is (there where to much moacros for me in K-Code):
How long (on a P133 for example) does it take under Linux until the custom Interrupt-Handler is called? I've written an Handler under DOS already, wich works fine. So I know that my Maschine is fast enough to do the job... But it would be much better if it could be done under Linux. By the way: The KHG helped me a lot until now!
