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 at gdatech.com bhup_sah at yahoo.com --- Khai Trinh <kqtrinh at yahoo.com> wrote: > > Hi folks, > > Can I register two devices irq numbers in a single > device driver?
