So the expectation is replace existing PASID from PASID table only if

yes. If no old_domain passed in, then it is just a normal attachment. As
you are working on AMD iommu, it would be great if you can have a patch to
make the AMD set_dev_pasid() op suit this expectation. Then it can be
incorporated in this series. 🙂
Perhaps this has been discussed before, but I can't recall. Out of
curiosity, why not introduce a specific replace_dev_pasid callback?
