That patch is for kernel 3.4. Get a newer kernel, which already has the patch.

Details are in gpsd time service howto.

add /dev/pps0 to the end of that. Then gpsd opens it.

Good.

Since you are starting as root, and you did not have /dev/pps0 on your
command line, neither would work. And when in doulbe just make it
666 for testing. That eliminates a lot of confusion.

Of course, attached to /dedv/ttyS2, which is not what you want
because your PPS is no on ttyS2 but on the gpio.

Because any sane hardware does not use GPIO for things that are
related to the serial port.

Nor will gpsd do as you expect going the way you are going.

Yes, nice for testing, nothing more.

Oh, and you also read the Raspi section in the INSTALL file?

Do it by the gpsd doc, and it will work fine.
