Typically DRM drivers use the DRM debugfs root entry. However, since Nouveau is heading towards a split into a core and a DRM driver, create a module specific debugfs root directory. Subsequent patches make use of this new debugfs root in order to store GSP-RM log bufferes (optionally beyond a device driver binding).
