There is a related I2C problem with EEPROMs and DDC monitors. DDC monitors look just like EEPROMs, the EEPROM driver can even read most of them. But there are DDC monitors that need special wakeup sequences before their ROMs will appear. EEPROM and DDC are both algo_bit clients. When you attach a bus to algo_bit both clients will run. There is concern that sending the special DDC wake up sequence down non-DDC buses might mess up the bus. A proposal was made to implement different classes of algo_bit clients but this was never implemented. Would a class solution help with the dvb problem too? -- Jon Smirl jonsmirl at gmail.com
