These domains have a few different properties compares to kernel owned domains: - They may be MANAGED domains, but created with special parameters. For instance aperture size changes/number of levels, different IOPTE formats, or other things necessary to make a vIOMMU workwhat is *MANAGED* domain? today we only have the separation between DMA domain and UNMANAGED domain. soon with Jason's cleanup all domains are called UNMANAGED.
It should be UNMANAGED domain. Best regards, baolu
