Q4 2022, TG or DevPartners?, needs resourcing?, needs resourcingYY
  1. Spike
Besides Zicboz, Spike either does not need to model the instructions (CBO.FLUSH, CBO.CLEAN, Zicbop) or can't model the effects (CBO.INVAL).
  2. OS
The Zicbom instructions require ratification to prevent fragmentation in the ecosystem and to avoid vendor-specific CMOs in the kernel; current OS support is based on trap-and-emulate in existing systems and real OS support will be provided in Q1. Zicboz and Zicbop have nothing OS specific in them.
