I think so, though I admit I don't remember using this personally since the introduction of e820 RAM mapping support. Dmesg will show if the memory is limited. For the swiotlb to effectively disable no RAM > 0x100000000 may be used. But this test isn't IMHO terribly important at this point - the driver makes invalid use of the DMA API and it has to change. The test could only explain _how_ exactly does it fail, we already know _why_ it does. -- Krzysztof Halasa
