Documentation: remove the PCI DMA API description in DMA-API.txt

2010-03-12T23:52:43Z

- remove the PCI DMA API description in DMA-API.txt - remove the descriptions of dma_unmap macros since PCI-DMA-mapping.txt has the same description.

dma-mapping: dma-mapping.h: add dma_set_coherent_mask

2010-03-12T23:52:42Z

dma_set_coherent_mask corresponds to pci_set_consistent_dma_mask. This is necessary to move to the generic device model DMA API from the PCI bus specific API in the long term. dma_set_coherent_mask works in the exact same way that pci_set_consistent_dma_mask does. So this patch also changes pci_set_consistent_dma_mask to call dma_set_coherent_mask. Signed-off-by: FUJITA Tomonori Cc: James Bottomley Cc: David S.

dma-mapping.h: add the dma_unmap state API

2010-03-12T23:52:42Z

Adds the following macros: DECLARE_DMA_UNMAP_ADDR(ADDR_NAME) DECLARE_DMA_UNMAP_LEN(LEN_NAME) dma_unmap_addr(PTR, ADDR_NAME) dma_unmap_addr_set(PTR, ADDR_NAME, VAL) dma_unmap_len(PTR, LEN_NAME) dma_unmap_len_set(PTR, LEN_NAME, VAL) The API corresponds to the pci_unmap state API. We'll move to this new generic API from the PCI specific API in the long term. As include/asm-generic/pci-dma-compat.h does, the pci_unmap API simply calls the new generic API for some time.

DMA-API.txt: remove dma_sync_single_range description

2010-03-12T23:52:40Z

dma_sync_single_for_cpu/for_device supports a partial sync so there is no point to have dma_sync_single_range (also dma_sync_single was obsoleted long ago, replaced with dma_sync_single_for_cpu/for_device). There is no user of dma_sync_single_range() in mainline and only Alpha architecture supports dma_sync_single_range(). So it's unlikely that someone out of the tree uses it.

DMA-API.txt: add dma_sync_single/sg API description

2010-03-12T23:52:40Z

This adds the description of the following eight function: dma_sync_single_for_cpu pci_dma_sync_single_for_cpu dma_sync_single_for_device pci_dma_sync_single_for_device dma_sync_sg_for_cpu pci_dma_sync_sg_for_cpu dma_sync_sg_for_device pci_dma_sync_sg_for_device It was unclear that the API permits a partial sync (some network drivers already do though). I made it clear that the sync_single API can do a partial sync but the sync_sg API can't. We could do a partial sync with the sync_sg API too, however, it's difficult for driver writers to correctly use the sync_sg API for a partial sync since the scatterlists passed in to the mapping API can't be modified. It's unlikely that driver writers want to do a partial sync with the sync_sg API (because the sync_sg API are usually used for block drivers). So I think that it's better to forbid a partial sync with the sync_sg API.
