Reference: https://lists.riscv.org/g/tech-ap-tee-io/topic/103498833#47

In case where there are multiple TDIs behind a single physical device, one TDI is assigned to TVM, how is the IOMMU programming handled in this case for TDIs still in untrusted domains? In the threat model, does VMM trust TSM to manage the relevant IOMMU programming? We do not see in IOMMU spec yet, the programming interface for TSM and how it is isolated from VMM.
