His latest patch series was posted here. https://lore.kernel.org/linux-iommu/20200903201839.7327-1-murphyt7@tcd.ie/ Thanks a lot! This series is a follow-up with below changes: 1. Add a quirk for the i915 driver issue described in Tom's cover letter. 2. Fix several bugs in patch "iommu: Allow the dma-iommu api to use bounce buffers" to make the bounce buffer work for untrusted devices. 3. Several cleanups in iommu/vt-d driver after the conversion. Please review and test.
