This driver was introduced in January 2011 and has been marked
BROKEN for almost its entire existence, since commit 95b90afec3
("pps: make pps_gen_parport depend on BROKEN") in March 2011.
It is unlikely anyone will fix the driver at this point.

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.
|

tristate "Dummy PPS generator (Testing generator, use for debug)"
|
|
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 TIO signal generator
|
|
which generates a pulse at a prescribed time based on the system clock.
|
|
It uses time translation and hrtimers to precisely generate a pulse.
|
|
This hardware is present on 2019 and newer Intel CPUs. However, this
|
|
driver is not useful without adding highly specialized hardware outside
|
|
the Linux system to observe these pulses.
|
|
|
|
To compile this driver as a module, choose M here: the module
|
|
will be called pps_gen_tio.
|
|
|
|
If unsure, say N.
