Hi, all

We have trouble in using DLA.

When the infer layers are not supported by DLA, we need to use --allowGPUFallback to use GPU.

I want to know how data is transferred between DLA and GPU during the fallback of GPU？

Is data transmitted directly from GPU to DLA or from DLA to CPU and then to GPU？

If possible, please explain the process of data transmission,thank you!
