2022-11-22 03:25:26 linux-kernel [PATCH] PPS elapsed real-time assert events/seq number
2022-03-31 10:00:35 linux-kernel [PATCH] Calculate the monotonic clock from the timespec clock to generate PPS elapsed real-time event value and stores the result into /sys/class/pps/pps0/assert_elapsed. Because we have requirements to make sure the delta between standard time, say the GPS Time, and elapsedRealtime < 1 millisecond, regular linux clock timestamp is not enough for our use case. The pin PPS will generate elapsedRealtime event at 1 sec boundary which is an exact value of the monotonic clock from the kernel PPS driver (/sys/class/pps/pps0/assert_elapsed). Whenever AP receives this pulse, kernel's pps driver timestamp this elapsedRealtime event and let this time available via sysfs node (/sys/class/pps/pps0/assert_elapsed) or the IOCTL call.
