Currently PPC64 JVM is not able to detect POWER9 CPUs. By adding support for POWER9-specific instructions it's possible to detect when JVM is running on POWER9 CPUs, allowing to set POWER9-specific features on the JVM.
In that sense 'darn' instruction introduced with Power 9 can be used to detect POWER9 CPUs. For instance, 'darn' instruction can't be disable on OS level.
