Re: Interrupt routine accessing i2c bus

Hi John,

Which Linux kernel are you using?

What about task_queues running in schedular queue in 2.4 Linux
kernels? They run in process context.

http://www.xml.com/ldd/chapter/book/ch06.html#t4

I was thinking of creating a task with
wait_for_completion(&xxx) and having the ISR do a
complete(&xxx) to wake the task.


Or use kernel_thread() and sleep, and let ISR wake it up?  USB hub
thread is an example:
