Up to you, imho is that fb are just bo with a bit of description. I didn't see much harm in creating an fb even if it was never going to be attached to any pipe. I don't have a solid usecase, just feels like it reduces the impact on the API. Hmm, however if we if (num_pipes == 0) driver_features &= ~DRIVER_MODESET; we will kill the unusable API at the ioctl boundary. > If yes then my plan to also query the planes which pixel formats/modifiers > to accept in addfb is going to hit hard times.
