WebOnce UTC-TAI offset is properly set, synchronize the System clock with PHC. sudo phc2sys -s eth0 -c CLOCK_REALTIME --step_threshold=1 \ --transportSpecific=1 -w -m The -s option specifies the PHC from eth0 interface as the master clock while the -c option specifies the System clock as slave clock. WebJul 28, 2024 · ptp4l. The ptp4l program represents the Linux implementation of PTP for the boundary and ordinary clocks. When using hardware timestamping, it directly synchronizes the PTP hardware clock (PHC) present on the NIC to the source clock. In order to get a clearer view of the capabilities of this PTP implementation, we can inspect its help page …

WebPTP hardware clock infrastructure for Linux. This patch set introduces support for IEEE 1588 PTP clocks in Linux. Together with the SO_TIMESTAMPING socket options, this presents a standardized method for developing PTP user space programs, synchronizing Linux with external clocks, and using the ancillary features of PTP hardware clocks. WebUsing PTP In order to use PTP, the kernel network driver for the intended interface has to support either software or hardware time stamping capabilities. 23.2.1.
