??? So you are told me that if my PPS source is connected with a single CPU GPIO I have to add a new driver to the kernel? I have to choose a proper major/minor numbers for just one PIN? =:-o > >RFC simply doesn't consider the fact that you can have a PPS source > >__without__ a filedes connected with, and a single filedes is > >considered __always__ connected with a single PPS source. > > That's the Unix way. But not PPS one. In several embedded systems the GPS antenna is connected with the serial port and the PPS source, which cames from the __same__ GPS antenna, is connected with a GPIO. How I should manage such case? Which fildes I should use? Also consider that NTPD currently manage only one filedes which should support both GPS antenna's data and PPS source. My patch can solve this problem.
