  TB4 + AMD ...
  háááát ... semmi se biztos .. megy a pin-pongozás ....
  én ezek alapján nem vagyok biztos a támogatásban ...

  """"
  AnandTech: When asked specifically if AMD-Vi meets the requirements for TB4, AMD stated:

  AMD: If the question is to do we support DMA? The answer is yes. Any questions about if this would satisfy another companies requirements for an interface they are developing would need to be directed at them.

  AnandTech: When we asked Intel to confirm if AMD-Vi met the requirements for TB4's DMA protection, we were given the following quote:

  INTEL: Thunderbolt is open to non-Intel-based systems. Like any other system, devices must pass Thunderbolt certification and end-to-end testing conducted by third-party labs. Thunderbolt 4 requirements include Intel VT-d based or an equivalent DMA protection technology that provides IO virtualization (often referred to as IO Memory Management Unit or IOMMU), as well as OS implementation support. If the equivalent technology supports prevention against physical attacks, then that should meet the requirement.
