It would be really lovely if such explanations would make it from ephemeral irc onto something more permanent like mailing lists, or even better, commit messages :-) So, why do we need this? I'm wondering since aside from userptr we'll have to unify how locking for bo works longer term (with all the dma_buf/ww_mutex stuff going on), not make it more distinct. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/intel-gfx
