User space needs to: a) Know enough about the GPU to be able to choose an SM version (and probably a few other things) which in turn is eventually required in order to run GPU programs, as shown in your merge request[1]. b) Display GPU information to the user. c) I'm sure to be overlooking something. > 2) If we provide the decoded values why do we need to expose the chip-id at all? OK, so maybe we don't?
