Also, I think Qualcomm has only started supporting MTE on Snapdragon 8 Elite Gen 5. Older and cheaper SoCs do not support it yet. Outside that, I think only Google Tensor, recent Exynos generations, and Apple A-series support MTE (though IIRC Apple has an improved extension of it).
Snapdragon 8 Elite Gen 5 has at support for MTE. It doesn't yet support running the whole kernel and userspace with it in practice as GrapheneOS requires but we're going to be working on it with Motorola and Qualcomm.
