Status of v1.12 privileged specification

Greg Chadwick


I appreciate no guarantees are possible but is it anticipated that the final v1.12 of the RISC-V privileged specification will be theĀ  v. 20211203 currently listed on the RISC-V website ( along with copy edits and the relevant already ratified extensions integrated (Smepmp, Smstateen, Sstc) as new chapters as the Svinval, Svnapot, Svpbmt extensions already are?

Am I right in my understanding that support of new extensions for a particular implementation is determined via the (as yet to be defined) structure pointed to by the mconfigptr CSR and that any instructions introduced by one of those extensions should cause an illegal instruction exception where that extension isn't supported?

Kind Regards,
