Now we want secure guests which means devices can # only access certain areas of guest physical memory; we are going to # use SWIOTLB for this purpose. # # This allows SWIOTLB for pseries. By default there is no change in # behavior. # # This enables SWIOTLB when the "swiotlb" kernel parameter is set to # "force". # # With the SWIOTLB enabled, the kernel creates a directly mapped DMA # window (using the usual DDW mechanism) and implements SWIOTLB on top # of that. # # Signed-off-by: Alexey Kardashevskiy # Signed-off-by: Michael Ellerman # <
