From mboxrd@z Thu Jan 1 00:00:00 1970 From: Damian Hobson-Garcia Subject: [PATCH v2 0/4] dma-mapping: Define dma_{alloc,free}_attrs() for all archs Date: Tue, 30 Apr 2013 12:01:39 +0900 Message-ID: <1367290899-10410-1-git-send-email-dhobsong@igel.co.jp> Cc: linux-s390@vger.kernel.org, catalin.marinas@arm.com, will.deacon@arm.com, linux-arm-kernel@lists.infradead.org, msalter@redhat.com, linux-c6x-dev@linux-c6x.org, deller@gmx.de, linux-parisc@vger.kernel.org, Damian Hobson-Garcia To: linux-kernel@vger.kernel.org Return-path: List-ID: List-Id: linux-parisc.vger.kernel.org Most architectures that define CONFIG_HAVE_DMA=y, have implementations for both dma_alloc_attrs() and dma_free_attrs(). All achitectures that do not define CONFIG_HAVE_DMA also have both of these definitions provided by dma-mapping-broken.h. Provide a default definition for the archs that define CONFIG_HAVE_DMA=y, but have no implementation for dma_{alloc,free}_attrs(). As I don't have hardware for any of these systems, the patches are only compile-tested where I could (arm64, s390) and untested for the archs where I couldn't find a readily available prebuilt cross-compiler (c6x, parisc). Changes from v1 --------------- arm64, s390: * Since these archs are using dma_ops, pass appropirate value for attrs to dma_ops->alloc(). * Indicate that these patches are compile teseted only (I don't have hardware) c6x, parisc: * Indicate that these patches are untested (I don't have cross compilers) Cheers, Damian Damian Hobson-Garcia (4): arm64: Provide default implementation for dma_{alloc,free}_attrs c6x: Provide default implementation for dma_{alloc,free}_attrs parisc: Provide default implementation for dma_{alloc,free}_attrs s390: Provide default implementation for dma_{alloc,free}_attrs arch/arm64/include/asm/dma-mapping.h | 17 +++++++++++------ arch/c6x/include/asm/dma-mapping.h | 3 +++ arch/parisc/include/asm/dma-mapping.h | 3 +++ arch/s390/include/asm/dma-mapping.h | 17 +++++++++++------ 4 files changed, 28 insertions(+), 12 deletions(-) -- 1.7.5.4
