Hi,
Expose the scheduler's sched_numa_find_closest() function, and use it in mlx5 device driver. This replaces the binary NUMA preference (local / remote) with an improved one that minds the actual distances, so that remote NUMAs with short distance are preferred over farther ones.
This has significant performance implications when using NUMA-aware memory allocations, improving the throughput and CPU utilization.
Regards, Tariq
