Hi, this patch-set introduces a new function into the iommu-api: iommu_commit(domain); It needs to be called whenever a some code changed a domain (either by attaching/detaching devices or by mapping/unmapping pages in the domain). IOMMU drivers can implement the new commit-callback to coalesce any cache flushing on the CPU and in the IOMMU hardware which is necessary after changes have been made to a domain. David, I think especially VT-d can benefit from such a callback. I will implement support for it in the AMD IOMMU driver and post a patch-set soon. Any comments, thoughts?
