To make fully dynamic pinning work (and especially reclaiming) we first need dma_buf fences, the new ww_mutexes and all that stuff since otherwise you can trivially deadlock in buffer reservations. But I think with Maarten's stuff we have a plan to get there, and this is just the first tiny step of a long journey. -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
