    driver core: move klist_children into private structure

    Broke our parisc build pretty badly because we touch the klists directly
    in three cases (AGP, SBA and GSC). Although GregKH will revert this
    patch, there's no reason we should be using the iterators directly, we
    can just move to the standard device_for_each_child() API.

    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.

  • d54b1fdb1   [PATCH] mark struct file_operations const 5 ... Browse Code »

    Many struct file_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

  • b312c33e3   [PARISC] Document that we tolerate "Relaxed Ordering" ... Browse Code »

    This means "DMA Read returns" can bypass "MMIO Writes".
    Violating the PCI specs in this case improves outbound DMA "flows"
    and is currently not required by any drivers.

    This is NOT a new behavior. Previous chipsets did this
    already and I believe ZX1 PDC was already setting this
    for hpux. I just want to further document the behavior.

    2.6.14-rc2-pa2 - make SBA more anal about invalidating pdir entries

    Previous code cleared the valid flag a pdir entry but it did NOT
    guarantee this change was visible to the PDIR before writing
    the PCOM register. Ie the SBA could pick up a stale entry if
    the write happened to hit the SBA before the cacheline was flushed
    from the cache.

    Long term, I think I want to make this a compile time flag.
    Developement tree should enable anal pdir checking by default
    and Debian can disable it with either a CONFIG option
    or one-line patch. fdc/sync options can only negatively affect
    performance though I haven't measure how much yet.
    If someone can run netperf TCP_RR across gige and compare
    -pa1 and -pa2, that would be sufficient.

    Cleaned up the use of "fdc" to make sure it's using "kernel"
    space id (specify sr0 but maps to sr4-7). It seems a bit fragile
    to assume "sr1" gets loaded with KERNEL_SPACE which is how the
    code works today.

    Tested on 32 and 64-bit SMP kernels on j6k.

    2.6.12-rc4-pa2 fix 32-bit support for Astro platforms
    o Since my last SBA code change, SBA could allocate more than 1GB of IOVA
    space on Astro boxes with more than 1GB of RAM when running 32-bit kernel.
    This is bad since IOMMU can only talk to the first 1GB at most.
    Kudos to jejb for quickly spotting that bug.

    o jejb also noted SBA should *always* reject DMA masks > 32-bits since
    DMA-mapping.txt indicates caller should try again with 32-bits.

    o off-by-one error when comparing the mask to IOVA space size.

    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!
