Creating the dma-buf should increase the gem object reference count too. So you should be able to unref the gem object after creating the dma-buf. That way the dma-buf is the only instance holding a reference to the gem object, and when the dma-buf goes away (due to userspace closing all file handles referring to it) the gem object will be released too because the refcount goes down to zero then. cheers, Gerd _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
