  • 51099005a   [IA64] swiotlb abstraction (e.g. for Xen) ... Browse Code »

    Add abstraction so that the file can be used by environments other than IA64
    and EM64T, namely for Xen.

  • cde14bbfb   [IA64] swiotlb bug fixes ... Browse Code »

    This patch fixes
    - marking I-cache clean of pages DMAed to now only done for IA64
    - broken multiple inclusion in include/asm-x86_64/swiotlb.h
    - missing call to mark_clean in swiotlb_sync_sg()
    - a (perhaps only theoretical) issue in swiotlb_dma_supported() when
    io_tlb_end is exactly at the end of memory

  • 65f87d8a8   [PATCH] x86_64: Fix swiotlb=force ... Browse Code »

    It was broken before. But having it is important as possible hardware
    bug workaround.

    And previously there was no way to force swiotlb if there is another IOMMU.
    Side effect is that iommu=force won't force swiotlb anymore even if there
    isn't another IOMMU.

  • 17a941d85   [PATCH] x86_64: Use function pointers to call DMA mapping functions ... Browse Code »

    AK: I hacked Muli's original patch a lot and there were a lot
    of changes - all bugs are probably to blame on me now.
    There were also some changes in the fall back behaviour
    for swiotlb - in particular it doesn't try to use GFP_DMA
    now anymore. Also all DMA mapping operations use the
    same core dma_alloc_coherent code with proper fallbacks now.
    And various other changes and cleanups.

    Known problems: iommu=force swiotlb=force together breaks
    needs more testing.

    This patch cleans up x86_64's DMA mapping dispatching code. Right now
    we have three possible IOMMU types: AGP GART, swiotlb and nommu, and
    in the future we will also have Xen's x86_64 swiotlb and other HW
    IOMMUs for x86_64. In order to support all of them cleanly, this
    patch:

    - introduces a struct dma_mapping_ops with function pointers for each
    of the DMA mapping operations of gart (AMD HW IOMMU), swiotlb
    (software IOMMU) and nommu (no IOMMU).

    - gets rid of:

    if (swiotlb)
    return swiotlb_xxx();

    - PCI_DMA_BUS_IS_PHYS is now checked against the dma_ops being set
    This makes swiotlb faster by avoiding double copying in some cases.

    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!
