nvmlNvlinkSetBwModeAsync_v1_t

struct nvmlNvlinkSetBwModeAsync_v1_t

Describes the parameters involved to setting Nvlink RBM mode asynchronously.

This structure holds the parameters needed to correctly set a Device’s Nvlink Reduced Bandwidth Mode asynchronously. Polling for NVML_GPU_FABRIC_STATE_COMPLETED from nvmlDeviceGetGpuFabricInfoV() is needed to check if the setting was applied.
