On 13.11.19 14:50, Jan Beulich wrote: Commit 1b00c16bdf ("AMD/IOMMU: pre-fill all DTEs right after table allocation") moved ourselves into a more secure default state, but didn't take sufficient care to also undo the effects when handing a previously disabled device back to a(nother) domain. Put the fields that may have been changed elsewhere back to their intended values (some fields amd_iommu_disable_domain_device() touches don't currently get written anywhere else, and hence don't need modifying here).
