it seems that the info methods provided by InteractiveUtils do not work with the CuDevice type. For example, in the following code
using CUDAdrv
dev = first(devices())
methodswith(dev)
methods(capability)
methodswith reports no matching method, while methods(capability) properly reports capability(dev::CuDevice) in CUDAdrv .... The same goes for supertype and subtypes. CuDevice is exported from CUDAdrv.
I know this is not a big deal, but I maybe it’s worth a mention.
julia> using CUDAdrv

CuDevice(0): Quadro RTX 5000
