Hello everyone.  
I am having a problem using CUDA.jl on a Jetson Orin DevKit.  
Even though everything seems to work, I get an error when I call `CUDA.versioninfo()`. Specifically, I get

```julia
CUDA runtime 12.6, local installation
CUDA driver 12.6
NVIDIA driver 540.4.0

[...]

Preferences:
- CUDA_Runtime_jll.local: true

1 device:
err = CUDA.NVML.NVMLError(CUDA.NVML.NVML_ERROR_NOT_FOUND)
ERROR: NVMLError: Not Found (code 6)
Stacktrace:
 [1] throw_api_error(res::CUDA.NVML.nvmlReturn_enum)
   @ CUDA.NVML ~/.julia/packages/CUDA/2kjXI/lib/nvml/libnvml.jl:8
 [2] check
[...]

```

Is this a problem? Why is there this error?  
Thank you!

NVML is optional, and not available on Tegra, so this issue is not problematic. `versioninfo` should work without though; can you file an issue with the full back-trace?

Sure. I’ll do it.  
For future reference, this is the full back-trace:
