Unable to use library to pull Computer/Bios/CPU/etc. data from virtual Arm server

[samfishman1]

Hello, I am trying to use the sysinfo to pull system data while running on an Arm server.
The following stack shows that there is a failure in a Go routine due to a SIGBUS error:

This error started occurring after attempting to implement the sysinfo library into the codebase.
If you are interested I may be able to provide access to the Arm server that was used (no access to the code). Hoping that the access to this server would potentially allow you time to debug so that I could use this library. Please let me know your thoughts and if you need more info in order to debug, thank you!

Hello @samfishman1

I suspect ARM architecture would be quite problematic to support.

There's cloneBytes() call in the stacktrace you provided, I'd suggest to first try compiling without the very last commit in the repo. It was provided by @lucklove to actually try to fix some pecularities with ARM architecture, but I wasn't able to test it.

Another thing to try is dmidecode utility. Sysinfo is very dependent on data provided in SMBIOS/DMI tables, which are always present on the x86 architecture, but that might not be true for virtual ARM environment. Which, I'm afraid, would render the whole library not really useful in such environment (if dmidecode itself is not working, or returning empty set).
