Which API call returns the nvidia ROP count?

[zebulon]

Hi there,
We are a bunch of Linux users/developers and would like to be able to check the ROP number from our nvidia Blackwell cards, following the missing ROP debacle. Problem is, nvidia-smi, which exists in Linux, does not seem to return this info. The proprietary driver on Linux is aligned with the Windows one, so we highly suspect this is possible. Would you be willing to share which API call is made to retrieve this information? Many thanks in advance.

If it's not listed in the public docs it's under NDA. Only way is to reach out to NVIDIA for NDA access to NVAPI

Thanks a lot W1zzard, we suspected something like this. So I suppose that for GPU-Z you are under NDA, is that correct?

Edit: I already looked into the NVAPI documentation. Does not seem to see it, but it is not easy to search. Especialy ROP can be referred as "Raster Operation Pipelines" but also sometimes "Render Unit".

A CUDA developer suggests as well to check whether Nsight Graphics lists those stats in the app profiler.
