Hello,
I see in the source (linux ver 3.3) that wake_up_interruptible function doesn't
sleep so I used in it an ISR but I'm getting 'BUG:scheduling while atomic'
message. (I'm not sure it's coming from this) I'm looking for the exact cause
but Is there any caveat when using wake_up_interruptible() in an ISR? (I found
some drivers use it in ISR, some use it in work_struct)
I also read in
http://www.slideshare.net/rampalliraj/tasklet-vs-work-queues?from_action=save
that tasklet is not allowed to sleep but work is. (because tasklet is not in
process context, but in bottom-half) I don't know if I have to move my
wake_up_interruptible function to tasklet or work(queue) or even it matters to
the current problem.
Any tip will be appreciated.
Regards,
Chan
