I am interested in new memory safety hardware. Investigating Google pixel. ARM has some nice things like MTE and PAC, but what of this new Titan chip? Pixel style? Anyone have a link to useful resource on mechanisms?

Pixel 7 will have MTE. PAC/BTI are secondary features.
Titan M2 largely has the same feature set as the earlier Titan M revisions but is now a custom RISC-V platform instead of a Cortex secure element design. It did bring some new features like app generated attestation keys.
MTE will likely not be enabled by default initially. It will likely get enabled for the OS and then introduced for apps targeting a future API level like API 34 (Android 14). It will break too much due to finding nearly all inter-object memory corruption occurring at runtime.

Awesome. So not out yet. We’ve got some prototype privilege separation work where we’d like to play around with it. Trying out the galaxy s22 but excited about vendor specific extensions. Thanks.
