Hi Rakesh
Hi all,

Can anyone suggest me how we can invoke the interrupt generated in the
kernel from the user application. I am getting the interrupt in the driver, I
want to update some register in the application, when the inettrupt will be
generated, Right now I am using polloing method. Continuously I am calling
read routines.
Thanks in advance,
Rakesh Jagota
First a remark : "How" isn't a good subject title because we could answer "
So".

What do you want to do exaclty. That your driver receive interrupt from the
hardware, read datas from it and after that warn an application that something
happened ?
If the answer is yes, I can say to you that is possible and even easy. To warn
your application from your driver it is a little bit harder because normally a
driver don't do that. A driver is unaware of the applications, It only answer
to request (read/write,ioctl requests)
Please be more specific and first erad the Linux Device Driver book from O
reilly. ( available as PDF freely, search for the address on this mailing
list)
