[PATCH v2 0/2] thunderbolt: Make iommu_dma_protection more accurate

Posted by Robin Murphy 4 years, 3 months ago

OK, here's chapter 3 in the story of "but I really just want to
remove iommu_present()", which is the second go at this approach
on the Thunderbolt end, but now improving the IOMMU end as well
since the subtlety of why that still matters has been clarified.

Thanks,
