| |
Most architectures that define CONFIG_HAS_DMA=y, have implementations for both dma_alloc_attrs() and dma_free_attrs(). All achitectures that do not define CONFIG_HAS_DMA also have both of these definitions provided by dma-mapping-broken.h.
Provide a default definition for the archs that define CONFIG_HAS_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).
Changes from v2 --------------- Correct commit log. CONFIG_HAVE_DMA should be CONFIG_HAS_DMA. Remove parisc from the patch series as it has already been merged.
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: * Indicate that this patch is untested (I don't have a cross compiler)
Cheers, Damian
