Kernel support for PPS and for in-kernel PLL utilizing one PPS input are two different things, at least in the Linux kernel. You are unlikely to have the in-kernel PLL support compiled in unless you are on older / exotic hardware or have compiled your own kernel with the requisite configuration changes. The in-kernel PLL is not compatible with the tickless scheduler model that most modern platforms use to enable energy-efficient operation. When you try toi switch the kernel PLL on in the NTP configuration you should see an error reported in the logs when ntpd starts.
