* doc: fix an incorrect suggestion to pass NULL for PCI like busesMatti Linnanvuori2008-04-28
| | | | | | | | | Fix an incorrect suggestion to pass NULL to pci_alloc_consistent for PCI like buses where devices don't have struct pci_dev (like ISA, EISA).

* Consistently use pdev as the variable of type struct pci_dev *.Matti Linnanvuori2008-04-28
| | | | | | | | | | | Update DMA mapping documentation to use 'pdev' rather than 'dev' in example code that calls routines expecting 'struct pci_device *', since 'dev' might make readers think they're passing 'struct device *' parameters.

* Update DMA-mapping documentationMatthew Wilcox2007-10-17
| | | | | | | | | | | | | | | | | | A couple of updates haven't considered whether the documentation makes sense as a whole any more. Three changes here: - Remove the reference to the "DAC Addressing for Address Space Hungry Devices" section which was deleted by Jan Beulich. - Remove the comment about DMA_24BIT_MASK which became obsolete when Tobias Klauser changed the code to actually use DMA_24BIT_MASK. - Remove the section "64-bit DMA and DAC cycle support" since it's fully covered above, and contains a reference to the section deleted by Jan.

| | | | | | | | | | | | | | | | | | Based on replies to a respective query, remove the pci_dac_dma_...() APIs (except for pci_dac_dma_supported() on Alpha, where this function is used in non-DAC PCI DMA code).

* Fix "can not" in Documentation and KconfigMatt LaPlante2006-10-03
| | | | | | | | | | | Randy brought it to my attention that in proper english "can not" should always be written "cannot". I donot see any reason to argue, even if I mightnot understand why this rule exists. This patch fixes "can not" in several Documentation files as well as three Kconfigs.

* [PATCH] Remove pci_dac_set_dma_mask() from Documentation/DMA-mapping.txtRolf Eike Beer2006-07-15
| | | | | | | | | | | | pci_dac_set_dma_mask() gives only a single match in the whole kernel tree and that's in this doc file. The best candidate for replacement is pci_dac_dma_supported().

* [PATCH] dma doc updatesDavid Brownell2006-04-14
| | | | | | | | | | | | | | | | | | | | | | | | This updates the DMA API documentation to address a few issues: - The dma_map_sg() call results are used like pci_map_sg() results: using sg_dma_address() and sg_dma_len(). That's not wholly obvious to folk reading _only_ the "new" DMA-API.txt writeup. - Buffers allocated by dma_alloc_coherent() may not be completely free of coherency concerns ... some CPUs also have write buffers that may need to be flushed. - Cacheline coherence issues are now mentioned as being among issues which affect dma buffers, and complicate/prevent using of static and (especially) stack based buffers with the DMA calls. I don't think many drivers currently need to worry about flushing write buffers, but I did hit it with one SOC using external SDRAM for DMA descriptors: without explicit writebuffer flushing, the on-chip DMA controller accessed descriptors before the CPU completed the writes.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
