c89755d1 - pps: generators: Add PPS Generator TIO Driver

Wed, 19 Feb 2025 04:06:16 +0000

pps: generators: Add PPS Generator TIO DriverThe Intel Timed IO PPS generator driver outputs a PPS signal usingdedicated hardware that is more accurate than software actuated PPS.The Timed IO hardware generates output events using the ART timer.The ART timer period varies based on platform type, but is less than 100nanoseconds for all current platforms. Timed IO output accuracy iswithin 1 ART period.PPS output is enabled by writing '1' the 'enable' sysfs attribute. Thedriver uses hrtimers to schedule a wake-up 10 ms before each event(edge) target time. At wakeup, the driver converts the target time interms of CLOCK_REALTIME to ART trigger time and writes this to the TimedIO hardware. The Timed IO hardware generates an event precisely at therequested system time without software involvement.Co-developed-by: Christopher Hall Signed-off-by: Christopher Hall Co-developed-by: Pandith N Signed-off-by: Pandith N Co-developed-by: Thejesh Reddy T R Signed-off-by: Thejesh Reddy T R Signed-off-by: Lakshmi Sowjanya D Reviewed-by: Eddie Dong Reviewed-by: Andy Shevchenko Acked-by: Rodolfo Giometti Signed-off-by: Subramanian Mohan Link: https://lore.kernel.org/r/20250219040618.70962-3-subramanian.mohan@intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/pps/generators/Makefile

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/generators/Makefile

e3a59056 - pps: use cflags-y instead of EXTRA_CFLAGS

pps: use cflags-y instead of EXTRA_CFLAGSCommit f77bf01425b1 ("kbuild: introduce ccflags-y, asflags-y andldflags-y") deprecates use of EXTRA_CFLAGS in the kernel build.This has been cleaned up in the whole kernel tree long ago, but this onesingle place must have been missed.Replace the EXTRA_CFLAGS use by the common pattern for such debug flags.No functional change.Signed-off-by: Lukas Bulwahn Acked-by: Rodolfo Giometti Link: https://lore.kernel.org/r/20240306120515.15711-1-lukas.bulwahn@gmail.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/pps/generators/Makefile
