Is there anything like this for more commodity arm cores (neoverse v2) or do we think the insights from apple silicon cores will generalize well to those other ARM architectures?

Linux 6.17 is adding support for arm's Branch Record Buffer Extension (BRBE), which does something similar of recording branches taken!

Not a new capability at all, but Linux support is new. The lag to adoption for this sort of stuff always seems very high. https://www.phoronix.com/news/Linux-6.17-ARM64
