In case my previous e-mail sounded too enthusiastic, I'm also pensive about this direction. I'm not sure I'm ready to totally give up on all of Linux WSI just yet. We definitely want to head towards memory fences and direct submission but I'm not convinced that throwing out all of interop is necessary. It's certainly a very big hammer and we should try to figure out something less destructive, if that's possible. (I don't know for sure that it is.) --Jason _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
