Description

https://docs.kernel.org/admin-guide/pm/amd-pstate.html

The pstate driver should be compiled into the kernel

CONFIG_X86_AMD_PSTATE=y
CONFIG_X86_AMD_PSTATE_DEFAULT_MODE=3

Then it could be optionally enabled with an config command:

set system option kernel amd-pstate-driver (active|passive|guided)

which sets the kernel argument to initcall_blacklist=acpi_cpufreq_init amd_pstate=guide to enable the amd pstate_driver on AMD Ryzen/Epyc CPUs
