My case was: I have a hall sensor connected to Beaglebone black, And
Userspace needed a wakeup once the interrupt occur (example: every rising
edge of GPIO). Before that, the program will register (ioctl) the User space
task pointer with my kernel module, then my kernel module start

Really? My device can wakeup thousands of times a second, what are
you going to do with that type of information?
Which
Wayback when I was working on some project to wake up userspace program for
every rising edge in GPIO pin (hall sensor), I use to send signal to the
PID from kernel, before that userspace has to register its PID with kernel
module. Max interrupts I have tested is some 100 times per second I.e. 100

Hi,
I want a user process to be notified on device wakeup so that I can print
some related information.
Which framework to use for this?(events, .. ??)
You can use netlink and uevent to do this job.
But just as Greg has pointed
Hi All,
Thank you for the replies. I understand that I can use netlink sockets.
Also, i have gone through various other possible ways :

I am looking for a simpler solution which uses existing information of sys
entries. That
