-From: Jan Beulich <jbeulich@suse.com>
-Subject: AMD/IOMMU: ensure suitable ordering of DTE modifications
-
-DMA and interrupt translation should be enabled only after other
-applicable DTE fields have been written. Similarly when disabling
-translation or when moving a device between domains, translation should
-first be disabled, before other entry fields get modified. Note however
-that the "moving" aspect doesn't apply to the interrupt remapping side,
-as domain specifics are maintained in the IRTEs here, not the DTE. We
-also never disable interrupt remapping once it got enabled for a device
-(the respective argument passed is always the immutable iommu_intremap).
-
-This is part of XSA-347.
