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)
