To compile this driver as a module, choose M here: the module will be called pps_gen_core. if PPS_GENERATOR config PPS_GENERATOR_DUMMY 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. config PPS_GENERATOR_PARPORT tristate "Parallel port PPS signal generator" depends on PARPORT && BROKEN 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. endif # PPS_GENERATOR
