The only way to use packed extension is 1. use cpu rv32 or rv64 2. turn on it by command line "-cpu rv32,x-p=true,Zpsfoperand=true,pext_spec=v0.9.4". Zpsfoperand is whether to support Zpsfoperand sub-extension, default value is true. pext_ver is the packed specification version, default value is v0.9.4. These properties can be specified with other values.
