+ tristate "PPS support"
+ help
+ PPS (Pulse Per Second) is a special pulse provided by some GPS
+ antennae. Userland can use it to get a high-precision time
+ reference.
+
+ Some antennae's PPS signals are connected with the CD (Carrier
+ Detect) pin of the serial line they use to communicate with the
+ host. In this case use the SERIAL_LINE client support.
+
+ Some antennae's PPS signals are connected with some special host
+ inputs so you have to enable the corresponding client support.
+
+ To compile this driver as a module, choose M here: the module
+ will be called pps_core.ko.
+
+if PPS
+
+config PPS_DEBUG
+ bool "PPS debugging messages"
+ help
+ Say Y here if you want the PPS support to produce a bunch of debug
+ messages to the system log. Select this if you are having a
+ problem with PPS support and want to see more of what is going on.
+
+config NTP_PPS
+ bool "PPS kernel consumer support"
+ depends on !NO_HZ_COMMON
+ help
+ This option adds support for direct in-kernel time
+ synchronization using an external PPS signal.
+
+ It doesn't work on tickless systems at the moment.
