ok.
BTW. A heads up: you are looping the mailing list, so you'd better use
the plain text format and avoid including pictures if it can be expressed
by text.

You should not mix ATS with PASID, ATS does not rely on PASID. You
should be able to test ATS without PASID. ATS is a performance feature,
so if you want to test it in system level, you need a benchmark to do
it. Or you can test it in pci transaction level, you would need tools
for it then. It's up to you.
