• RISC-V Unprivileged Spec - contains info on core "user-mode" instructions . Note there are specifications regarding other extensions, they can be found on the official RISC-V website.
• RISC-V Privileged Spec - contains info on core "system-mode" instructions and the RISC-V equivalent of an x86 MSR - the CSR.
