GrapheneOS project: pixel 11 no longer supports hardware memory tagging (MTE); GrapheneOS might skip the the whole pixel 11 series
-
Graphene choosing to die on the hardware MTE hill has always seemed weird to me. It's one feature but it excludes 99% of the phones except the Pixel. GrapheneOS has so much to offer besides it, and nowadays they could use Rust as a workaround anyway.
Apparently the Linux kernel can emulate MTE in software:

The software MTE support in the kernel apparently predates the hardware support of the same, based on the above link.
Admittedly I might be misunderstanding something here, my confidence level is only 65%.
