PPS generators are special hardware which are able to produce PPS
|
|
(Pulse Per Second) signals.
|
|
|
|
To compile this driver as a module, choose M here: the module
|
|
will be called pps_gen_core.

|
|
help
|
|
If you say yes here you get support for a PPS debugging generator
|
|
(which generates no PPS signal at all).
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called pps_gen-dummy.

|
|
help
|
|
If you say yes here you get support for a PPS signal generator which
|
|
utilizes STROBE pin of a parallel port to send PPS signals. It uses
|
|
parport abstraction layer and hrtimers to precisely control the signal.
