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
