State of arbitration and i2c_gpio?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello people,

I'd like to ask whether anybody is working on adding arbitration support to
i2c_algo_bit.c. The code still has the old "FIXME do arbitration here" comments,
added five years ago when the I²C was imported into Linux 2.3.34pre1. :-/

If not, and I'm going to have to do that myself … my main question is, even
before I get to that -- how do I even detect that the bus is idle? Turn
interrupts off and busy-loop-check that both SCL and SDA stay high for at least
one and a half clock periods?

Ugh.
