We don't have any arch specific scatterlist now that parisc switched over to the generic one. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

frv: Provide dummy dma_mmap_coherent() and dma_get_sgtable()

2013-01-29T07:11:15+00:00

frv/allmodconfig: drivers/media/v4l2-core/videobuf2-dma-contig.c: In function ‘vb2_dc_mmap’: drivers/media/v4l2-core/videobuf2-dma-contig.c:204: error: implicit declaration of function ‘dma_mmap_coherent’ drivers/media/v4l2-core/videobuf2-dma-contig.c: In function ‘vb2_dc_get_base_sgt’: drivers/media/v4l2-core/videobuf2-dma-contig.c:387: error: implicit declaration of function ‘dma_get_sgtable’ For architectures using dma_map_ops, dma_mmap_coherent() and dma_get_sgtable() are provided in . Frv does not use dma_map_ops, hence it should implement them itself. For now, use dummy implementations that just return -EINVAL, until the API has been finalized.

dma-mapping: remove dma_is_consistent API

2010-08-11T15:59:21+00:00

Architectures implement dma_is_consistent() in different ways (some misinterpret the definition of API in DMA-API.txt). So it hasn't been so useful for drivers. We have only one user of the API in tree. Unlikely out-of-tree drivers use the API. Even if we fix dma_is_consistent() in some architectures, it doesn't look useful at all. It was invented long ago for some old systems that can't allocate coherent memory at all. It's better to export only APIs that are definitely necessary for drivers. Let's remove this API.

dma-mapping: unify dma_get_cache_alignment implementations

2010-08-11T15:59:21+00:00

dma_get_cache_alignment returns the minimum DMA alignment. Architectures defines it as ARCH_DMA_MINALIGN (formally ARCH_KMALLOC_MINALIGN). So we can unify dma_get_cache_alignment implementations. Note that some architectures implement dma_get_cache_alignment wrongly. dma_get_cache_alignment() should return the minimum DMA alignment. So fully-coherent architectures should return 1. This patch also fixes this issue. Signed-off-by: FUJITA Tomonori Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

dma-mapping: frv: remove the obsolete and unnecessary DMA API comments

2010-03-12T23:52:42+00:00

pci_dma_sync_single was obsoleted long ago. All the comments are generic, not architecture specific, simply describes some of the DMA-API (and frv has the same comments in three files). Documentation/DMA-API.txt have more detailed descriptions. This removes the above obsolete and unnecessary DMA API comments. Let's describe the DMA API in only Documentation/DMA-API.txt.
