2009-01-29Documentation: move DMA-mapping.txt to Doc/PCI/Randy Dunlap
Move DMA-mapping.txt to Documentation/PCI/. DMA-mapping.txt was supposed to be moved from Documentation/ to Documentation/PCI/. The 00-INDEX files in those two directories were updated, along with a few other text files, but the file itself somehow escaped being moved, so move it and update more text files and source files with its new location.

2009-01-06x86, ia64: convert to use generic dma_map_ops structFUJITA Tomonori
This converts X86 and IA64 to use include/linux/dma-mapping.h. It's a bit large but pretty boring. The major change for X86 is converting 'int dir' to 'enum dma_data_direction dir' in DMA mapping operations. The major changes for IA64 is using map_page and unmap_page instead of map_single and unmap_single.

2009-01-06set up dma_ops appropriatelyFUJITA Tomonori
This patch introduces a global pointer, dma_ops, which points to an appropriate dma_mapping_ops that the kernel should use. This is a common way to handle multiple dma_mapping_ops (X86, POWER, and SPARC). dma_ops is set in platform_dma_init. We also set it by hand where machvec_init is callev via subsys_initcall. - IA64_DIG_VTD uses vtd_dma_ops. - IA64_HP_ZX1 uses sba_dma_ops. - IA64_HP_ZX1_SWIOTLB uses hwsw_dma_ops. - IA64_SGI_SN2 uses sn_dma_ops. - The rest use swiotlb_dma_ops.

2008-07-26dma-mapping: add the device argument to dma_mapping_error()FUJITA Tomonori
Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER architecture does: This enables us to cleanly fix the Calgary IOMMU issue that some devices are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423). I think that per-device dma_mapping_ops support would be also helpful for KVM people to support PCI passthrough but Andi thinks that this makes it difficult to support the PCI passthrough (see the above thread). So I CC'ed this to KVM camp. Comments are appreciated. A pointer to dma_mapping_ops to struct dev_archdata is added. If the pointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it's NULL, the system-wide dma_ops pointer is used as before. If it's useful for KVM people, I plan to implement a mechanism to register a hook called when a new pci (or dma capable) device is created (it works with hot plugging). It enables IOMMUs to set up an appropriate dma_mapping_ops per device. The major obstacle is that dma_mapping_error doesn't take a pointer to the device unlike other DMA operations. So x86 can't have dma_mapping_ops per device. Note all the POWER IOMMUs use the same dma_mapping_error function so this is not a problem for POWER but x86 IOMMUs use different dma_mapping_error functions. The first patch adds the device argument to dma_mapping_error. The patch is trivial but large since it touches lots of drivers and dma-mapping.h in all the architecture. This patch: dma_mapping_error() doesn't take a pointer to the device unlike other DMA operations. So we can't have dma_mapping_ops per device. Note that POWER already has dma_mapping_ops per device but all the POWER IOMMUs use the same dma_mapping_error function. x86 IOMMUs use device argument.

2008-04-09[IA64] make IOMMU respect the segment boundary limitsFUJITA Tomonori
IA64's IOMMU implementation allocates memory areas spanning LLD's segment boundary limit. It forces low level drivers to have a workaround to adjust scatter lists that the IOMMU builds.

2007-10-12[IA64] add driver for ACPI methods to call native firmwareBjorn Helgaas
This driver for HPQ5001 devices installs a global ACPI OpRegion handler. AML methods can use this OpRegion to call native firmware entry points. ACPI does not define a mechanism for AML methods to call native firmware interfaces such as PAL or SAL. This OpRegion handler adds such a mechanism. After the handler is installed, an AML method can call native firmware by storing the arguments and firmware entry point to specific offsets in the OpRegion. When AML reads the "return value" offset from the OpRegion, this handler loads up the arguments, makes the firmware call, and returns the result.

2007-10-12[SCSI] simscsi: Free scsi host on errorMatthew Wilcox
If scsi_add_host returned an error, the host would never be freed. We need to call scsi_host_put() if an error happens. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-10[NET]: Make device event notification network namespace safeEric W. Biederman
Every user of the network device notifiers is either a protocol stack or a pseudo device. If a protocol stack that does not have support for multiple network namespaces receives an event for a device that is not in the initial network namespace it quite possibly can get confused and do the wrong thing. To avoid problems until all of the protocol stacks are converted this patch modifies all netdev event handlers to ignore events on devices that are not in the initial network namespace. As the rest of the code is made network namespace aware these checks can be removed. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-09-01[IA64] Cleanup HPSIM code (was: Re: Enable early console for Ski simulator)Peter Chubb
After my last patch we have a new header file for HP simulator use. Here's code to use it for stuff that used to have `extern' statements inline in the code. Functionality should not change with this patch. Signed-off-by: Peter Chubb <peterc@gelato.unsw.edu.au> Signed-off-by: Tony Luck <tony.luck@intel.com>
2007-09-01[IA64] Enable early console for Ski simulatorPeter Chubb
This patch cleans up the `enable early console for SKI' patch (471e7a44848f467c9b83adc3463d019d2fa8817f), and 1. potentially allows the gensparse_defconfig to work again. (there are other problems running a generic kernel on Ski) 2. fixes the `console registered twice' problem. 3. Cleans up the code by moving the `extern hpsim_cons' declaration to a new asm/hpsim.h file. Thanks to Jes for comments.
