GrapheneOS not supporting Pixel 11s?

GrapheneOS Mastodon GrapheneOS (@GrapheneOS@grapheneos.social) We have a partial port of GrapheneOS to the Pixel 11 series after a week of work on it. We're unable to complete the port due to lack of support for ARM hardware memory tagging in software, firmware and near certainly hardware. It appears Google cut an important security feature to save money.

If GrapheneOS stops supporting future Pixels, and Motorola is only targeting the flagship market for their compatible phones, we’re looking at truly dark days ahead.

  cat /proc/cpuinfo gives me a bunch of copies of this (one per CPU core):

  $ cat /proc/cpuinfo

  Not sure how “MTE3” relates to “EMTE”…

    Feat_mte4 is emte. You just have normal mte (it’s not just normal mte, mte3 means you also have mte2 and can do I think four different kinds of tagged memory management. It’s really powerful but it isn’t emte).

    E: I just wanna toot my own horn here and congratulate me on correctly remembering details from someone else’s work while posting on the toilet. Not today cognitive decline, not today.
