- According to RISC-V crypto spec, Zvkb extension is a proper subset of the Zvbb extension. - Reference: https://github.com/riscv/riscv-crypto/blob/1769c2609bf4535632e0c0fd715778f212bb272e/doc/vector/riscv-crypto-vector-zvkb.adoc?plain=1#L10 Signed-off-by: Jerry Zhang Jian <jerry.zhangjian@sifive.com> --- target/riscv/tcg/tcg-cpu.c | 4 ++++ 1 file changed, 4 insertions(+)
