CoreFreq is using kernel module parameters. All possible parameters are managed using standard commands.
Do you know the Register for this current limit ? |

Thanks, i get it.
I'm not sure, i find some code in the Throttled repo:
On my cpu, if i don't increase the current limit, the cpu power will be limited at 100w, though i set PL to 180w.

Do you have any link to the source code of this repo ?
This MSR Register seems interesting: we need its index value and its protocol specification. |

Did you disable this prefetcher on purpose or it's a miss reading of CoreFreq ? |

Here is the link: https://github.com/erpalma/throttled/blob/master/throttled.py
I haven't change it, it seems been set off by default? |

I have a compatible
Whereas all the other MSR (listed in throttled) are already implemented in CoreFreq |

It's an architectural register, try to test directly MSR_IA32_TEMPERATURE_TARGET:

Sadly, the TDC option on my cpu is missing and i also cannot read MSR_TURBO_POWER_CURRENT_LIMIT. Anyway, thanks for your help. If you would like to test MSR_OC_MAILBOX function, i'm glad to provide a ssh link to my platform for testing. |

13th Generation datasheet vol.2 specifies a bit more about BIOS MAILBOX MMIO Registers, although I have not found the possible commands |

Same, i can't find any intel official document about this msr register. But i found a pdf which discribe some details of this register, in 2.2 chapter and below References chapter there is a more detailed table about it. |

I'm using corefreq to overclock my cpu, but i can't find any configuaration file. It's too troublesome to reconfigure every time I start up.
ps: corefreq lacks the ability to adjust the upper current limit, i'm using throttled to implement this function。
