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
