There's an equivalent functionality which allows any in-kernel user to register and receive timing interrupts. That said, I think it would be better to use other timing sources. Except rtctimer.c, which other driver is using it? When I searched for it, rtctimer was the only user and I believe its usage is not widespread. -- Best regards, Alessandro Zummo, Tower Technologies - Torino, Italy http://www.towertech.it
