SOLVED amd_pstate is not working

Kernel: 6.12.4-zen1-1-zen
Cpu: amd ryzen 5 3600
Gpu: Radeon rx 6750 XT
DE: Hyprland
When I run the command 'journalctl -b -p err', it outputs the following: 'Dec 14 21:34:56 archlinux kernel: amd_pstate: min_freq(0) or max_freq(0) or nominal_freq(0) value is incorrect Dec 14 21:34:56 archlinux kernel: amd_pstate: failed to register with return -19'.
I checked the BIOS settings, everything seems fine. In the GRUB config, I have already set 'amd_pstate=enable'.
When I run 'sudo modprobe amd_pstate', the output is: 'modprobe: FATAL: Module amd_pstate not found in directory /lib/modules/6.12.4-zen1-1-zen'. There is no output when I run 'lsmod | grep amd_pstate'.
I also ran: 'zcat /proc/config.gz | grep AMD_PSTATE', and the output is: 'CONFIG_X86_AMD_PSTATE=y CONFIG_X86_AMD_PSTATE_DEFAULT_MODE=3 CONFIG_X86_AMD_PSTATE_UT=m'.
Can anyone suggest what I might be missing or doing wrong?

Re: SOLVED amd_pstate is not working

This indicates that your BIOS is too old.
Please update your BIOS to the latest version and the latest agesa version, otherwise amd-pstate is not supported.

Thanks a lot, I tried a lot of things before even thinking of a BIOS update. This worked.
