  • d59d36a7f   PCI: Remove unused pcibios_select_root() (again) ... Browse Code »

    a6c140969b46 ("Delete pcibios_select_root") removed pcibios_select_root().
    But a7db50405216 ("PCI: remove pcibios_scan_all_fns()") added a few copies
    back, probably with some incorrect merge conflict resolutions.

    Remove the still-unused pcibios_select_root() definitions.

    Everybody uses the generic pcibios_resource_to_bus() supplied by the core
    now, so remove the ARCH_HAS_GENERIC_PCI_OFFSETS used during conversion.

  • 36a66cd6f   PCI: add generic pcibios_resource_to_bus() ... Browse Code »

    This replaces the generic versions of pcibios_resource_to_bus() and
    pcibios_bus_to_resource() in asm-generic/pci.h with versions that use
    pci_resource_to_bus() and pci_bus_to_resource().

    The replacements are equivalent except that they can apply host
    bridge window offsets when the arch has supplied them by using
    pci_add_resource_offset().

    Each arch can convert to using pci_add_resource_offset() individually by
    removing its device resource fixups from pcibios_fixup_bus() and supplying
    ARCH_HAS_GENERIC_PCI_OFFSETS. ARCH_HAS_GENERIC_PCI_OFFSETS can be removed
    after all have converted.

  • a7db50405   PCI: remove pcibios_scan_all_fns() ... Browse Code »

    This was #define'd as 0 on all platforms, so let's get rid of it.

    This change makes pci_scan_slot() slightly easier to read.

  • d7c4f1b78   asm-generic: make pci.h usable directly ... Browse Code »

    Some generic code is using the horribly misnamed PCI_DMA_BUS_IS_PHYS
    from asm/pci.h. This makes sure that an architecture without PCI
    support does not have to define this itself but can rely on the
    asm-generic version.

  • 085ae41f6   [PATCH] Make sparc64 use setup-res.c ... Browse Code »

    There were three changes necessary in order to allow
    sparc64 to use setup-res.c:

    1) Sparc64 roots the PCI I/O and MEM address space using
    parent resources contained in the PCI controller structure.
    I'm actually surprised no other platforms do this, especially
    ones like Alpha and PPC{,64}. These resources get linked into the
    iomem/ioport tree when PCI controllers are probed.

    So the hierarchy looks like this:

    iomem --|
    PCI controller 1 MEM space --|
    device 1
    device 2
    etc.
    PCI controller 2 MEM space --|
    ...
    ioport --|
    PCI controller 1 IO space --|
    ...
    PCI controller 2 IO space --|
    ...

    You get the idea. The drivers/pci/setup-res.c code allocates
    using plain iomem_space and ioport_space as the root, so that
    wouldn't work with the above setup.

    So I added a pcibios_select_root() that is used to handle this.
    It uses the PCI controller struct's io_space and mem_space on
    sparc64, and io{port,mem}_resource on every other platform to
    keep current behavior.

    2) quirk_io_region() is buggy. It takes in raw BUS view addresses
    and tries to use them as a PCI resource.

    pci_claim_resource() expects the resource to be fully formed when
    it gets called. The sparc64 implementation would do the translation
    but that's absolutely wrong, because if the same resource gets
    released then re-claimed we'll adjust things twice.

    So I fixed up quirk_io_region() to do the proper pcibios_bus_to_resource()
    conversion before passing it on to pci_claim_resource().

    3) I was mistakedly __init'ing the function methods the PCI controller
    drivers provide on sparc64 to implement some parts of these
    routines. This was, of course, easy to fix.

    So we end up with the following, and that nasty SPARC64 makefile
    ifdef in drivers/pci/Makefile is finally zapped.

  • 43c347355   [PATCH] pci and yenta: pcibios_bus_to_resource ... Browse Code »

    In yenta_socket, we default to using the resource setting of the CardBus
    bridge. However, this is a PCI-bus-centric view of resources and thus needs
    to be converted to generic resources first. Therefore, add a call to
    pcibios_bus_to_resource() call in between. This function is a mere wrapper on
    x86 and friends, however on some others it already exists, is added in this
    patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where
    is its pcibios_resource_to_bus() ?).

    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!
