Description

mlx5dv_ts_to_ns(3) Converts a host byte order device_timestamp from HCA core clock units into the corresponding nanosecond wallclock time. structmlx5dv_clock_info can be retrieved using mlx5dv_get_clock_info(3). The greater the difference between the device reporting a timestamp and the last mlx5dv_clock_info update, the greater the inaccuracy of the clock time conversion.

Name

mlx5dv_ts_to_ns - Convert device timestamp from HCA core clock units to the corresponding nanosecond counts

Return Value

Timestamp in nanoseconds

Synopsis

#include<infiniband/mlx5dv.h>uint64_tmlx5dv_ts_to_ns(structmlx5dv_clock_info*clock_info,uint64_tdevice_timestamp);
