Hi folks, Can I register two devices irq numbers in a single device driver? If that's possible, then I can write a smart isr to figure out the interrupt is from which device and handle the irq accordingly. Any inputs would be appreciated... Thanks, --Khai Yahoo!

Hi guys, U are right. U can have two or more than that irq in a device driver. Let' say if u have request_irq(irq no(17), handle1.....) request_irq(irq no(18), handle2.....) For os it does not matter from where u have registered. So whenever interrupt 17 will occur handle1 will be executed... in another case handle2...... So u can always do that...i guess so bye Bhupi Deep into Silicon with linux... www.gdatech.com bhupi@gdatech.com bhup_sah@yahoo.com
