    iommu/amd: Set global dma_ops if swiotlb is disabled · 52717828
    Joerg Roedel 提交于
    Some AMD systems also have non-PCI devices which can do DMA.
    Those can't be handled by the AMD IOMMU, as the hardware can
    only handle PCI. These devices would end up with no dma_ops,
    as neither the per-device nor the global dma_ops will get
    set. SWIOTLB provides global dma_ops when it is active, so
    make sure there are global dma_ops too when swiotlb is
    disabled.
