I would recommend having a look at advanced side-channel PCIe bus DMA taps used by game cheats. They use a second computer along with an external HDMI mask-overlay mixer, to dump the target computers internal game-engine state through unencrypted DMA access to the overlay channel. Thus, gives the cheaters x-ray vision and aim-bot features for games protected by kernel level anti-cheat software.
BTW, project summary is here https://www.pwnshow.com/investigations/INV-006/
In comparing xen to qubes bulletins does the vastly different user count affect the analysis?

Highly entertaining nuisance users. =3
Does this work with IOMMU?
Unknown, but there were a few obvious bios options I saw that are needed to make the kits performant with some systems.
I still find it absurd people would go that far to cheat at a game. =3
