Inspired by your advice , I have changed the method of preventing
from being unloaded while "intrpt_routine" is still in the task queue.Now it
"insmod" and "rmmod" in my linux(2.4.18-3,not on mips) at any time.But
When I port it to mips_linux, it get some errors as you can see in my mail to
firstname.lastname@example.org . It confuses me .Why? And what should I MUST pay
or what should I MUST learn if I I want to implement schedualing a function to
on every timer interrupt.
Thank you again and eagering your enthusiastic again!
