https://wiki.gentoo.org/wiki/Hardware_detection

see the ??????? for i2c-tools package? the command we're missing is 'i2cdetect'. within that context, the user would probably only need the
Code:
i2cdetect -l
command. It outputs a neat little list of i2c buses, each with a description that should look deeply related to the kernel drivers necessary.

Correct me if I'm wrong, but card0-DP-1 and so on refers to the first DisplayPort (DP) on the first graphics card. and there's plenty more graphics related bit-bus entries to expect.

Note that other uses of the i2cdetect can destroy your hardware, according to the manpage.

So far, it looks like a nice way to probe for the SMBus/etc driver(s) to compile into your kernel, without having to dive deep into lshw, or pull up a desktop for lshw-gtk.
