It wouldn't fix radeon, but it would at least unblock your intel card again. I haven't specifically added a special case to attempt to unblock external fences, but I've considered it. :-) Actually the i915 reset stuff relies crucially on being able to kick all waiters holding driver locks. Since the current fence code only exposes an opaque wait function without exposing the underlying wait queue we won't be able to sleep on both the fence queue and the reset queue. So would pose a problem if we add fence_wait calls to our driver. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
