Linux: CPU Ryzen 9 7950X not supported

   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.

	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.

	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...

	You can try sending off a support ticket to ASRock and ask directly: 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.

	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.

	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....).

	You should probably check with your distro forums/support.

	I made a request here: 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.

	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) this depends on underlying firmware/hardware. So where to go from here? Thanks!
