    removes all references to it.

  • 997ea58eb   USB: rename usb_buffer_alloc() and usb_buffer_free() users ... Browse Code »

    For more clearance what the functions actually do,

    usb_buffer_alloc() is renamed to usb_alloc_coherent()
    usb_buffer_free() is renamed to usb_free_coherent()

    They should only be used in code which really needs DMA coherency.

    All call sites have been changed accordingly, except for staging
    drivers.

    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.

  • fbf54dd32   USB: usb/dma doc updates ... Browse Code »

    This patch updates some of the documentation about DMA buffer management
    for USB, and ways to avoid extra copying. Our understanding of the issues
    has improved over time.

    - Most drivers should *avoid* the dma-coherent allocators. There are
    a few exceptions (like the HID driver).

    - Some methods are currently commented out; it seems folk writing
    USB drivers aren't doing performance tuning at that level yet.

    - Just avoid highmem; there's no good way to pass an "I can do highmem
    DMA" capability through a driver stack. This is easy, everything
    already avoids highmem. But it'd be nice if x86_32 systems with much
    physical memory could use it directly with network adapters and mass
    storage devices. (Patch, anyone?)

    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!
