i915 and nouveau also support encoder slaves, and they also have them all built-in. And I think requesting the module at driver init time (where I mean any point in time between when the master module loads and userspace first starts using it) seems fraught with with deadlock issues if we have to wait for it. So imo in the current drm state there is no way you can built slave drivers as modules. It's simply broken. I agree that it'd be nice to have a better solution, but atm I don't even have an idea what it is. But applying duct-tape in ->firstopen is certainly not the right way. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/dri-devel
