Hi, > + if (!dma_map_sg(dev->dev, xen_obj->sgt->sgl, xen_obj->sgt->nents, > + DMA_BIDIRECTIONAL)) { > + ret = -EFAULT; > + goto fail_free_sgt; > + } Hmm, so it seems the arm guys could not come up with a suggestion how to solve that one in a better way. Ok, lets go with this then. But didn't we agree that this deserves a comment exmplaining the purpose of the dma_map_sg() call is to flush caches and that there is no actual DMA happening here? cheers, Gerd _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
