[lm-sensors] why must Dell machine use i8k?

[JACK MA]

Hello,

I have a Dell Inspiron and a Acer laptop. I do not need to install any
other package to control the fan of the Acer one. I think the Linux kernel
support it very well. But, why does this not work on the Dell laptop?

thanks,
jack

Hi Jack,

Firmware on Tesla cars can be remotely upgraded, at least on Model S.
For most if not all other cars this has to be done by the dealer,
if it is possible in the first place. Why does remote upgrade
not work on other cars as well ?

Please feel free to submit a set of patches to improve the situation
to your liking.

Wrong people to blame. Dell decided a few years ago to drop supporting
Linux on desktop and Laptop systems, and to only suport Linux on servers.
That was not an engineering decision; it was a management decision
(possibly influenced by a certain OS vendor located in Redmond, WA).
The correct response would be to not buy a Dell system if you intend
to install Linux on it, and to let Dell know about it.

Kind of. Note that i8k already implements the software layer, though
it is far from perfect.
