Hello,I am ok with this one.
currently i8k driver for DELLDIAG SMM operations (charger,
battery, hotkeys, temperature and fan control) supports two
1) old /proc/i8k char device
2) new hwmon interface
Driver now lives in char subsystem, but nowadays I think lot of
people are interested only in hwmon interface which provides
temperature & fan control. Power management and hotkeys support
(which is missing in 2) but provided by 1)) is already handled by
ACPI or input subsystem for new laptops.
Also name "i8k" is really non intuitive what it means and
supports... (I was told it is abbreviation for Inspirion 8000
model which was probably first dell model supported by that
DELLDIAG interface). Now driver is used on Vostro, Latitude and
also Precision and XPS models. I think at least "dell" should be
part of driver name and config option.
So I have idea for some changes:
1) Move driver from char subsystem to hwmon
2) Rename driver from i8k to something like delldiag or dellsmmMight be problematic, as it would break existing configurations
3) Add new CONFIG_ option to enable/disable /proc/i8k device and
compile only hwmon interface support
