There does not seem to be a search function for the forum on the Linux-Hardware.org website and I have not found an explanation of how to contextualize the information. I'm currently looking at getting a 2022 Gigabyte AORUS 17 YE5 and l am researching Linux compatibility. LHw has 4 total scans. All were around the end of August/September 2022, and all seem to use an older generic kernel. There are several flagged failures in some of these, but when I click on these, it brings up a long list of other machines that also use the same device and all of these lists of other devices contain working entries. I think this means that, contextually these do work, it just requires a newer kernel that supports them. Please correct me if I am wrong here.
I'm kinda confused about what is meant by "detected" versus "working."
I'm also confused about what the (i) means. I think it means some machines with this hardware have had issues, but I am not sure.
Lastly, on other machines results listings I have seen the test listed as running under Kubernetes and the uefi bios log had a bunch of Microsoft names in the path. That just seems super weird to me. Is there anything else to glean about hardware compatibility and potential gotchas in this data, especially in the context of laptop hardware firmware and proprietary exploitative nonsense? Do you have any other resources I should check for hardware issues before purchasing?
If you want to check that a machine you're buying is compatible with Linux, a good place to start is to google how to install drivers for the computer's components on Linux. Check the common problem areas (WiFi, graphics, sound, etc.) and see if you find lots of other people complaining about those components. If you find evidence that a driver is available, or you can't seem to find any info either way, it's probably fine.
I can't really answer the question you had regarding this site you found, but that is my general strategy for checking Linux hardware compatibility.
Also make sure that the retailer you're buying from has a reasonable returns policy, just in case you get it, install Linux (or run it from a live USB, to avoid wiping the disk before you know you're good), and discover something doesn't work.
