No, the underlying C++ is not hardware specific and there is no Soapy driver code in GR. We added some hardware-specific YAML files to make life easier. Users can add their own, too, easily enough. There are generic ones too at the moment, but to do things right, they have to know the characteristics of every possible device (e.g, gains) and they're a maintenance nightmare. It's pretty easy to throw one block for each sdr you're likely to use on the screen and disable the ones you're not using, if you switch between them frequently.
