Are asking about the abstract model, or the specific implementation? The former is quite obvious is think (utilize the respective interrupt to get notified of completions and suspend the execution in the current context until then), while the latter isn't clear at all at this point, due to it being necessary to inspect all involved code paths to see how exactly suspension can be carried out. Also, QI is - afaik - a VT-d specific feature anyway, i.e. doesn't have a direct equivalent on the AMD side...
