Thanks,
I still think that if people want to do this they should wrap their stuff in a dvsec..
If we have no choice but to inject a PASID cap for this to work then I don't think we should quirk every device, but punish those that don't use DVSEC/etc
So.. If PASID injection is needed then block the unmanaged space and add quirks for devices that really need it. Otherwise leave it alone.
