🤔 I'll have a look a bit later this week.

Please let me know if there's anything I can do to help. I have some experience in Go and since this related to my work, I can spend a bit of time on it.

Do you know what an ideal solution to this would look like for you (if you think this should be fixed)? If you let me know I can look into implementing it

Thanks for all the work you're putting into this project - facter is an extremely useful tool for me!

@Scandiravian, I'm glad to hear you find it helpful.

I will try to think through the implications for a bit today. I'll post my thoughts here.

Happy to review PRs if you want to implement the fix 🙏

Yes. I got this error too: error: unsigned json number 9223372036854775808 outside of Nix integer range

Cause by:

$ jq '.smbios.memory_64_error[] | {array_address, device_address}' facter.json
{
  "array_address": 9223372036854775808,
  "device_address": 9223372036854775808
}

A quick review of mapping from hwinfo s underlying data model shows some places I can reduce the size from uint.

I'll spend some time today doing this and converting any explicit usages of uint64_t to string and see if anything breaks in nixos-facter-modules. I don't think any values are actively being used, so I can safely break the format without a version bump.

@brianmcgee maybe a those addresses could be formatted as hex strings. That's also more readable and compact.

I've just tested #193 on the R760 servers, that were experiencing the issue and the fix resolved it 😊
