SWIOTLB support found in arch/powerpc/Kconfig

The configuration item CONFIG_SWIOTLB:

• prompt: SWIOTLB support
• type: bool
• depends on: (none)
• defined in arch/powerpc/Kconfig
• found in Linux kernels: 2.6.31–2.6.39, 3.0–3.19, 4.0–4.17

Help text

Support for IO bounce buffering for systems without an IOMMU. This allows us to DMA to the full physical address space on platforms where the size of a physical address is larger than the bus address. Not all platforms support this.

found in arch/x86/Kconfig

The configuration item CONFIG_SWIOTLB:

• prompt:
• type: bool
• depends on: CONFIG_X86_64
• defined in arch/x86/Kconfig
• found in Linux kernels: 2.6.24–2.6.39, 3.0–3.19, 4.0–4.17

Help text

Support for software bounce buffers used on x86-64 systems which don't have a hardware IOMMU. Using this PCI devices which can only access 32-bits of memory can be used on systems with more than 3 GB of memory. If unsure, say Y.
