86b525be - drivers pps: add PPS generators support

Fri, 08 Nov 2024 07:31:12 +0000

drivers pps: add PPS generators supportSometimes one needs to be able not only to catch PPS signals but toproduce them also. For example, running a distributed simulation,which requires computers' clock to be synchronized very tightly.This patch adds PPS generators class in order to have a well-definedinterface for these devices.Signed-off-by: Rodolfo Giometti Link: https://lore.kernel.org/r/20241108073115.759039-2-giometti@enneenne.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/pps/Makefile

46b402a0 - pps: add parallel port PPS signal generator

Thu, 13 Jan 2011 01:00:59 +0000

pps: add parallel port PPS signal generatorAdd PPS signal generator which utilizes STROBE pin of a parallel port tosend PPS signals. It uses parport abstraction layer and hrtimers toprecisely control the signal.[akpm@linux-foundation.org: fix build]Signed-off-by: Alexander Gordeev Acked-by: Rodolfo Giometti Cc: john stultz Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds List of files: /linux-6.15/drivers/pps/Makefile

697fb85f - pps: LinuxPPS clients support

Wed, 10 Mar 2010 23:23:45 +0000

pps: LinuxPPS clients supportEach PPS source can be registered/deregistered into the system by usingspecial modules called "clients". They simply define the PPS sources'attributes and implement the time signal registration mechanism.This patch adds a special directory for such clients and adds a dummyclient that can be useful to test system integrity on real systems.[akpm@linux-foundation.org: coding-style fixes]Signed-off-by: Rodolfo Giometti Cc: David Woodhouse Cc: Greg KH Cc: Alan Cox Cc: Alexander Gordeev Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds List of files: /linux-6.15/drivers/pps/Makefile

eae9d2ba - LinuxPPS: core support

Wed, 17 Jun 2009 23:28:37 +0000

LinuxPPS: core supportThis patch adds the kernel side of the PPS support currently named"LinuxPPS".PPS means "pulse per second" and a PPS source is just a device whichprovides a high precision signal each second so that an application canuse it to adjust system clock time.Common use is the combination of the NTPD as userland program with a GPSreceiver as PPS source to obtain a wallclock-time with sub-millisecondsynchronisation to UTC.To obtain this goal the userland programs shoud use the PPS APIspecification (RFC 2783 - Pulse-Per-Second API for UNIX-like OperatingSystems, Version 1.0) which in part is implemented by this patch. Itprovides a set of chars devices, one per PPS source, which can be used toget the time signal. The RFC's functions can be implemented by accessingto these char devices.Signed-off-by: Rodolfo Giometti Cc: David Woodhouse Cc: Greg KH Cc: Randy Dunlap Cc: Kay Sievers Acked-by: Alan Cox Cc: Michael Kerrisk Cc: Christoph Hellwig Cc: Roman Zippel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds List of files: /linux-6.15/drivers/pps/Makefile
