There exist\n more than one function for allocating and freeing the buffers:\n currently these 3 are used dma_{alloc, free}_coherent,\n dma_{alloc,free}_writecombine, dma_{alloc,free}_noncoherent.\n\n For most of the systems these calls are almost equivalent and can be\n interchanged. For others, especially the truly non-coherent ones\n (like ARM), the difference can be easily noticed in overall driver\n performance. Sadly not all architectures provide implementations for\n all of them, so the drivers might need to be adapted and cannot be\n easily shared between different architectures. The provided patches\n unify all these functions and hide the differences under the already\n existing dma attributes concept. The thread with more references is\n available here:\n\n http://www.spinics.net/lists/linux-sh/msg09777.html\n\n These patches are also a prerequisite for unifying DMA-mapping\n implementation on ARM architecture with the common one provided by\n dma_map_ops structure and extending it with IOMMU support. More\n information is available in the following thread:\n\n http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819\n\n More works on dma-mapping framework are planned, especially in the\n area of buffer sharing and managing the shared mappings (together with\n the recently introduced dma_buf interface: commit d15bd7ee445d\n \"dma-buf: Introduce dma buffer sharing mechanism\").\n\n The patches in the current set introduce a new alloc/free methods\n (with support for memory attributes) in dma_map_ops structure, which\n will later replace dma_alloc_coherent and dma_alloc_writecombine\n functions.\"\n\nPeople finally started piping up with support for merging this, so I\u0027m\nmerging it as the last of the pending stuff from the merge window.\nLooks like pohmelfs is going to wait for 3.5 and more external support\nfor merging.\n\n* \u0027for-linus\u0027 of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:\n common: DMA-mapping: add NON-CONSISTENT attribute\n common: DMA-mapping: add WRITE_COMBINE attribute\n common: dma-mapping: introduce mmap method\n common: dma-mapping: remove old alloc_coherent and free_coherent methods\n Hexagon: adapt for dma_map_ops changes\n Unicore32: adapt for dma_map_ops changes\n Microblaze: adapt for dma_map_ops changes\n SH: adapt for dma_map_ops changes\n Alpha: adapt for dma_map_ops changes\n SPARC: adapt for dma_map_ops changes\n PowerPC: adapt for dma_map_ops changes\n MIPS: adapt for dma_map_ops changes\n X86 \u0026 IA64: adapt for dma_map_ops changes\n common: dma-mapping: introduce generic alloc() and free() methods\n" }, { "commit": "9adc537452e1e341cabd39a02d4788d3c510b0e2", "tree": "17911e3c2e58cf20759e001ce718c8514a6a4027", "parents": [ "645ae3bce3e62541f8dc2701dde2a2791d842b6c" ], "author": { "name": "Marek Szyprowski", "email": "m.szyprowski@samsung.com", "time": "Wed Dec 21 16:55:33 2011 +0100" }, "committer": { "name": "Marek Szyprowski", "email": "m.szyprowski@samsung.com", "time": "Wed Mar 28 16:36:42 2012 +0200" }, "message": "common: dma-mapping: introduce mmap method\n\nIntroduce new generic mmap method with attributes argument.\n\nThis method lets drivers to create a userspace mapping for a DMA buffer\nin generic, architecture independent way.\n\nSigned-off-by: Marek Szyprowski \u003cm.szyprowski@samsung.com\u003e\nAcked-by: Kyungmin Park \u003ckyungmin.park@samsung.com\u003e\nReviewed-by: Arnd Bergmann \u003carnd@arndb.de\u003e\n" }, { "commit": "645ae3bce3e62541f8dc2701dde2a2791d842b6c", "tree": "0d2ee42e8e7e25e182f8b31d907680c8e2402b2d", "parents": [ "77345520c465ccb85e4ed2c8ba352a159f60c2e4" ], "author": { "name": "Marek Szyprowski", "email": "m.szyprowski@samsung.com", "time": "Wed Dec 21 16:55:57 2011 +0100" }, "committer": { "name": "Marek Szyprowski", "email": "m.szyprowski@samsung.com", "time": "Wed Mar 28 16:36:41 2012 +0200" }, "message": "common: dma-mapping: remove old alloc_coherent and free_coherent methods\n\nRemove old, unused alloc_coherent and free_coherent methods from\ndma_map_ops structure.\n\nSigned-off-by: Marek Szyprowski \u003cm.szyprowski@samsung.com\u003e\nAcked-by: Kyungmin Park \u003ckyungmin.park@samsung.com\u003e\nReviewed-by: Arnd Bergmann \u003carnd@arndb.de\u003e\n" }, { "commit": "613c4578d4079a14dbee76ef7e0c80f635522fe3", "tree": "cd833ec1ae6f510153ffddb3ff3e22d2443b832d", "parents": [ "c16fa4f2ad19908a47c63d8fa436a1178438c7e7" ], "author": { "name": "Marek Szyprowski", "email": "m.szyprowski@samsung.com", "time": "Wed Mar 28 16:36:27 2012 +0200" }, "committer": { "name": "Marek Szyprowski", "email": "m.szyprowski@samsung.com", "time": "Wed Mar 28 16:36:27 2012 +0200" }, "message": "common: dma-mapping: introduce generic alloc() and free() methods\n\nIntroduce new generic alloc and free methods with attributes argument.\n\nExisting alloc_coherent and free_coherent can be implemented on top of the\nnew calls with NULL attributes argument.

The patches for other IOMMUs are only compile tested.\n\nThis patch:\n\nAdd a new structure, device_dma_parameters, including dma information. A\npointer to device_dma_parameters is added to struct device.\n\n- there are only max_segment_size and segment_boundary_mask there but we\u0027ll\n move more dma stuff in struct device (like dma_mask) to struct\n device_dma_parameters later. segment_boundary_mask is not supported yet.\n\n- new accessors for the dma parameters are added. So we can easily change\n where to place struct device_dma_parameters in the future.\n\n- dma_get_max_seg_size returns 64K if dma_parms in struct device isn\u0027t set\n up properly. 64K is the default max_segment_size in the block layer.\n\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nAcked-by: Jeff Garzik \u003cjeff@garzik.org\u003e\nCc: James Bottomley \u003cJames.Bottomley@steeleye.com\u003e\nAcked-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "96532babc3e2ec4e0fce891d64319f183f043855", "tree": "04b9a1fcc771078807d7c0a3aabcfd1e1c7dcd4f", "parents": [ "4fe3fcaca008ec24bb4b9cb4a9e4d17bee06c755" ], "author": { "name": "Robert P.
