Hello. Philips I2C specs mentions it is possible to receive a hardware interrupt from an I2C device when data is ready, so one doesn't have to use software polling. Is it supported in Linux I2C buses in general ? Can I2C chip drivers register an interrupt handler ? Is it supported by the Linux parallel port I2C bus ? how is the interrupt transfered ? via a third line ? Thank You naziir. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
