From 782e6769c0df744e773dc2acff71c974b3bba4e9 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 16 Apr 2018 15:24:51 +0200 Subject: dma-mapping: provide a generic dma-noncoherent implementation Add a new dma_map_ops implementation that uses dma-direct for the address mapping of streaming mappings, and which requires arch-specific implemenations of coherent allocate/free. Architectures have to provide flushing helpers to ownership trasnfers to the device and/or CPU, and can provide optional implementations of the coherent mmap functionality, and the cache_flush routines for non-coherent long term allocations.
