    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.

  • 0de26520c   cpumask: make irq_set_affinity() take a const struct cpumask ... Browse Code »

    Impact: change existing irq_chip API

    Not much point with gentle transition here: the struct irq_chip's
    setaffinity method signature needs to change.

    Fortunately, not widely used code, but hits a few architectures.

    Note: In irq_select_affinity() I save a temporary in by mangling
    irq_desc[irq].affinity directly. Ingo, does this break anything?

  • 8d8bb39b9   dma-mapping: add the device argument to dma_mapping_error() ... Browse Code »

    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.

    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.

    We are in the process of making all the IOMMUs respect the segment boundary
    limits to remove such work around in LLDs. This patch is for IA64's IOMMU.

  • 28eda5b8b   [IA64] add driver for ACPI methods to call native firmware ... Browse Code »

    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.

  • e9dc86534   [NET]: Make device event notification network namespace safe ... Browse Code »

    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.
