Unsupported CPU type (i7-12700K) #44

Hi,

When I try to start the processI am greeted with an error telling me my CPU is unsupported:

$ sudo intel_lpmd --loglevel=debug --no-daemon
[1720281527][DEBUG]lpmd_main begin
[1720281527][DEBUG]CPUID 0x00000000: eax = 0x00000020 ebx = 0x756e6547 ecx = 0x6c65746e edx = 0x49656e69

[1720281527][DEBUG]Non Mobile platform detected
[1720281527][INFO]Unsupported CPU type

But I find this message somewhat confusing, and also cannot find information about supported CPUs in the README.

Are non mobile platform not supported? Is 12th gen not supported or is my specific CPU not supported?

I would appreciate it if more information was included in the log message and/or the README about which CPUs are (un)supported

as the first step, I just improve the log message. can you please check the latest main branch and see if that is better?

Yeah it's better thank you. But, I'm still confused because nowhere in the README or articles I read does it mention that you need to have a mobile platform and why. Do desktops not benefit from lower power consumption while idle? If that is the case, why do we have a hybrid architecture on desktop in the first place? But maybe that is besides the point...

Thanks either way :)
