mlx5dv_ts_to_ns - Convert device timestamp from HCA core clock units to the corresponding nanosecond counts
#include <infiniband/mlx5dv.h> uint64_t mlx5dv_ts_to_ns(struct mlx5dv_clock_info *clock_info, uint64_t device_timestamp);
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.
