Hi! My system essentially is: - ASROCK 650M PG Riptide mainboard - Ryzen 9 7950X cpu with the latest BIOS updates 1.11.AS03 [Beta] flashed. The OS is Linux OpenSuSe Tumbleweed with default kernel 6.1.3-1 . When I issue in the command line: 'fwupdmgr security --force' I see as part of my result: ??Supported CPU: Failed As written here ( https://github.com/fwupd/fwupd/issues/4887#issuecomment-1330929271" rel="nofollow - https://github.com/fwupd/fwupd/issues/4887#issuecomment-1330929271 ) this depends on underlying firmware/hardware. So where to go from here? Thanks! |

I made a request here: https://github.com/fwupd/fwupd/issues/5415" rel="nofollow - https://github.com/fwupd/fwupd/issues/5415 . The answer is that the information is not provided by the firmware so that the OS kernel cannot receive the CPU data. |

You should probably check with your distro forums/support. -------------

From the request to fwupd above a new documentation entry came along: "On AMD APUs or CPUs this information is reported on kernel 5.19 or later via the `ccp` kernel module. If the kernel module isn't loading on it's own, this is a kernel bug and should be reported to kernel bugzilla. If the kernel module has loaded but you still don't have data this is NOT a fwupd bug. You will have to contact your motherboard or system manufacturer to enable reporting this information." So I checked that the responsible kernel module ccp loaded (and reported CPU not supported), the kernel is way newer than 5.19 (6.1....). |

Socket Family Number Core Frequency FSB Cache Power Validated BIOS Bootable since BIOS AM5 Ryzen 9 7950X(100-000000514-00) 170W Raphael 4.5GHz 1.06 All What part number do you have? I would downgrade the BIOS to 1.06 but see what ASRock says. The 1.11 beta might be a special one for something. ------------- ASRock B450M Pro4 16 GB DDR4, 500 watt PS, AMD Ryzen-5 5600, NVidia GTX-1050, 5.70 BIOS |

You can try sending off a support ticket to ASRock and ask directly: https://event.asrock.com/tsd.asp" rel="nofollow - https://event.asrock.com/tsd.asp While Linux isn't officially supported they have helped others from the forums, via support ticker, before. Good luck. -------------

What OS are you on? If Linux, could you check in the command line: fwupdmgr security --force | grep CPU and see whether you get: "CPU supported" or not... |

I have a AMD Ryzen 5 5600 that works fine. $ fwupdmgr security --force | grep CPU ??Supported CPU: Failed I am using kernel-6.2 but I had 5.19. I suspect that is a red herring. Can you get the BIOS screen because I would assume you couldn't without a supported CPU. ------------- ASRock B450M Pro4 16 GB DDR4, 500 watt PS, AMD Ryzen-5 5600, NVidia GTX-1050, 5.70 BIOS |

Yes, BIOS and everything is there. I don't have a problem with CPU usage and performance. However, I build my own number cruncher for professional work and need somehow to show to my clients that my IT infrastructure complies to standards. A very easy way would be to use the HSI-Level that you can get by the fwupd tool. As it seems from the contact to fwupd people the motherboard needs to carry the CPU info (PSP/CCP) to the OS, so that kernel modules can use it. |
