[qzylinra]

This has basically been abandoned and is no longer maintained; FreeBSD has already removed the package. kernelslacker/x86info#15

Things done

• Built on platform:
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• Tested, as applicable:
  • NixOS tests in nixos/tests.
  • Package tests at passthru.tests.
  • Tests in lib/tests or pkgs/test for functions and "core" functionality.
• Ran nixpkgs-review on this PR. See nixpkgs-review usage.
• Tested basic functionality of all binary files, usually in ./result/bin/.
• Nixpkgs Release Notes
  • Package update: when the change is major or breaking.
• NixOS Release Notes
  • Module addition: when adding a new NixOS module.
  • Module update: when the change is significant.
• Fits CONTRIBUTING.md, pkgs/README.md, maintainers/README.md and other READMEs.

It doesn't even work on my 10-year-old x86_64 machine...

Seems to work for me:

% /nix/store/shlxw24p2iqpz7pw5ihyv9ixy3avxn2x-x86info-0-unstable-2021-08-07/bin/x86info
x86info 2025-07-26
Found 32 identical CPUs
Extended Family: 8 Extended Model: 7 Family: 15 Model: 113 Stepping: 0
CPU Model (x86info's best guess): Unknown CPU 0x870f10
Processor name string (BIOS programmed): AMD Ryzen 9 3950X 16-Core Processor

Monitor/Mwait: min/max line size 64/64, ecx bit 0 support, enumeration extension
SVM: revision 1, 32768 ASIDs, np, lbrVirt, SVMLock, NRIPSave, TscRateMsr, VmcbClean, FlushByAsid, DecodeAssists, PauseFilter, PauseFilterThreshold
Address Size: 48 bits virtual, 48 bits physical
The physical package has 32 of 128 possible cores implemented.
 running at an estimated 3.50GHz

Is it useful? I don't know, but it seems to work.

Not sure why you're closing that immediately. I would expect this to stay open for ~a week to give the maintainer @jcumming time to react and say something about it.

My i7-4790K was identified as a Xeon E3. I guess Unknown CPU does work better here...

Right. "Unknown" is also what the upstream issue says as the reported problem. Reporting something else entirely... seems really broken, indeed.
