> POWER10 has emerged on the roadmap

First public information on Power11 are there. Power11 must be the very first IBM POWER/Power generation with no ISA or microarchitectural improvements in the CPU core over the previous generation.

"CPU, MMU and user (ELF_HWCAP) features are unchanged vs P10."
