MLX5DV_TS_TO_NS(3) Library Functions Manual MLX5DV_TS_TO_NS(3)
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.
