Same with the Google Pixels and their Samsung Exynos modem. Neither you nor GrapheneOS users have any idea at all what's going on in their cellular transceivers. What will it be for the upcoming Motorola phone?

Hi daneel, what would you like GrapheneOS to do while you develop your own formally verified, open hardware, open source firmware/OS baseband processor they can use? Sit on their hands doing nothing or making the best of the least worst options currently available?

Pixel has an IOMMU - are you implying that’s being defeated, or that you weren’t aware of it?
