Linux kernel 4.17 added a new amd_pstate CPU performance scaling driver:

kernel.org/doc/html/latest/admin-guide/pm/amd-pstate.html

Unfortunately, on my Zenbook UM425IA, this driver does not work. Despite the CPU (Ryzen 5 4500U) supporting cppc, it appears to be disabled in BIOS, with no option of enabling it. The following error is being shown:

amd_pstate: the _CPC object is not present in SBIOS

Please consider either enabling the CPPC by default, or adding an option for enabling it. Thank you.
