MLX5DV_TS_TO_NS(3)         Library Functions Manual         MLX5DV_TS_TO_NS(3)

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

SYNOPSIS
       #include <infiniband/mlx5dv.h>

       uint64_t mlx5dv_ts_to_ns(struct mlx5dv_clock_info *clock_info,
                            uint64_t device_timestamp);

DESCRIPTION
       mlx5dv_ts_to_ns(3) Converts a host byte order device_timestamp from HCA
       core clock units into the corresponding nanosecond wallclock time.

       struct mlx5dv_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.


RETURN VALUE
       Timestamp in nanoseconds
