Adding RISC-V Vector Cryptography Extension support to QEMU

RISC-V is an open source instruction set architecture (ISA) based on reduced instruction set computer (RISC) principles. Codethink has been working with the RISC-V CPU architecture for several years. We’ve done some internal projects around hardware design, toolchain support and porting a desktop environment. We also do commercial work in this area, and a project team recently added support to QEMU for an extension to the RISC-V instruction set that provides Vector Cryptography. Read on for details of how they did this work.
