> The RISC-V QEMU port implements the following specifications: > - RISC-V Instruction Set Manual Volume I: User-Level ISA Version 2.2 > - RISC-V Instruction Set Manual Volume II: Privileged ISA Version 1.9.1 > - RISC-V Instruction Set Manual Volume II: Privileged ISA Version 1.10
What is the reason to support the legacy 1.9.1 privileg spec? That support seems to make a mess of quite a lot of the code, and has been superseded quite a while ago.
