Can't get attribute for CU_DEVICE_ATTRIBUTE_D3D12_CIG_SUPPORTED #184
Description
When I call cuDeviceGetAttribute with cuda.CUdevice_attribute.CU_DEVICE_ATTRIBUTE_D3D12_CIG_SUPPORTED I get the error <CUresult.CUDA_ERROR_INVALID_VALUE: 1>.
Seems like it might be an off-by-one error since it's the last value in the Enum CUdevice_attribute?
Here is some code to reproduce the problem.

What's your CUDA Python version and driver version?
python -c "from cuda import __version__; print(__version__)"(but this will change later, see [EPIC] RFC:cudanamespace cleanup #75),pip list | grep cudaif you installed it via pip, orconda list cuda-pythonif via conda.nvidia-smi(we just need the "CUDA Version" here)apowers313 commentedon Oct 21, 2024
CUDA Python: 12.6.0
CUDA Driver: 12.4

This happens because the driver support for
CU_DEVICE_ATTRIBUTE_D3D12_CIG_SUPPORTEDwas added since CUDA 12.5, so to use it you need to update both your CUDA driver and CUDA sw (in this case, cuda-python) to >=12.5.I am not sure why this is not mentioned in the CUDA Release Notes, but the way I checked this is to search
CU_DEVICE_ATTRIBUTE_D3D12_CIG_SUPPORTEDin the driver API docs, which are versioned so that you can search the same term by jumping across different minor versions. It takes a few clicks to get to the right URL, but you can see the version number is encoded as part of it, e.g. https://docs.nvidia.com/cuda/archive/12.5.1/cuda-driver-api/index.html. The first time this enumerator appeared was CUDA 12.5.0.btw what's your use case of CIG? Do you have some graphics rendering pipeline written in Python?

Use case was iterating all the enums to print out all the device capabilities to the screen.
Thanks for the help.
