Note that you are not forced to use i915_params. If you have gvt only module options that you don't want exposed outside of gvt, just create them within gvt. Having said that, I would strongly advise against having module options, and I would advise you to go the dyndebug route instead of copying a rectangular wheel. -Chris _______________________________________________ Intel-gfx mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/intel-gfx
