So looking a bit closer, I'm needing this due to my using dev_get_cma_area() to get the default cma area for the dmabuf cma_heap. Do you have a suggestion for how to get a reference to the default CMA area without exporting dma_contiguous_default_area? Would it be preferred to move dev_get_cma_area() into the .c file and EXPORT_SYMBOL_GPL that function? thanks -john _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
