The only way to use packed extension is 1. use cpu rv32 or rv64 2. turn on it by command line "-cpu rv64,x-p=3Dtrue,Zp64=3Dtrue,pext_spec=3Dv0.9.2". Zp64 is whether to support Zp64 extension, default value is true. pext_ver is the packed specification version, default value is v0.9.2. These properties can be specified with other values.
