GrapheneOS says it will not support Google’s Pixel 11 because the Tensor G6 chip lacks Memory Tagging Extension (MTE), a hardware security feature central to the privacy-focused operating system. Bootloader analysis and leaked Google documents suggest MTE was deliberately removed, prompting GrapheneOS to recommend older Pixels while exploring support for a forthcoming Motorola flagship.
According to article, the reason is that they can’t make their memory writing as fast as other memory chips that have MTE (for example apple’s).
Yea more overhead with secure chips. But they can do it ofc, they have done it so far. They choose not to, and in last minute without any heads up.
