They are only command sequences whose starting addresses you encode into the execlists context. Why have you allocated a ringbuf not an object? Why have you allocated 2 pages when you only need one, and could even find space elsewhere in the context.... And these should be pinned alongside the context *not permanently*. I want a debug mode that limits us to say 16M of GGTT space so that these address space leaks are easier to demonstrate in practice. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
