[lm-sensors] labels for it87 compared to mbmon

[lm-sensors] labels for it87 compared to mbmon

[Stefan Monnier]

`xmbmon' gives me 3 temperatures, called MB/CPU/chip.
`sensors' gives me three temperatures from the `it87' module and those
temperatures seem to match perfectly the ones I get from xmbmon, but
their label is just temp1/temp2/temp3.

Any reason why lm-sensors uses generic labels?

                CPU label seems right since it's the one most
                susceptible to change under CPU load"

Hmm, xmbmon, the tool which is no longer developed since, hm, 2008 if
not worse? If you're using that on recent hardware, it's not going to
be very helpful.

The proper labels are motherboard model dependent. There's no way
xmbmon can guess them. So either they have a database of known
motherboards and your board is in it, or they put random labels that
worked for one board once upon a time, and you're lucky if it also
works on yours.

We (lm-sensors / hwmon kernel drivers) play it safe and don't claim
mappings we're not sure of. We don't know what temperature sensors are
connected to IT87xxF chips in general, and we say exactly that by
naming them just "temp1", "temp2", etc.

Once you have figured out the proper labels, just add them to your
board-specific configuration file in the proper chip section.

That very one, yes.

Don't worry, this hardware is older than the xmbmon binary (itself dated
Mar 16 2008).

I see, so I guess I just got lucky.  That makes sense, thank you,
