Description Miroslav Lichvar 2010-07-29 13:18:03 UTC 
Description of problem:
In 2.6.34 was included serial port PPS support. This is mainly useful with GPS receivers, it allows time synchronization with accuracy better than 1 microsecond.

ntp and chrony packages are compiled with PPS support since F-13, so the only missing piece is kernel to have it working out of the box.

CONFIG_PPS=m
CONFIG_PPS_CLIENT_LDISC=m

Version-Release number of selected component (if applicable):
kernel-2.6.35-0.56.rc6.git1.fc14.x86_64

seems ok. I'll flip it on in cvs when the dist-git conversion is done, so hopefully we'll get a build out with it next week sometime.

Comment 3 Chuck Ebbert 2010-08-01 23:39:09 UTC 
I've enabled in F-13 2.6.34-31 as well.
