# \[PATCH 03/28\] drm/nouveau/gk20a: stop setting DMA\_ATTR\_NON\_CONSISTENT - From: Christoph Hellwig \ - Date: 2020-08-19 07:09:41 - List: linux-arm-kernel - Page: https://ratatoskr.run/linux-arm-kernel/2020/08/6073574 - Thread: https://ratatoskr.run/linux-doc/2020/08/6073543/t.md ```text DMA_ATTR_NON_CONSISTENT is a no-op except on PARISC and some mips configs, so don't set it in this ARM specific driver part.
