CONFIG_I8K: Legacy /proc/i8k interface of Dell laptop SMM BIOS hwmon driver

General informations

The Linux kernel configuration item CONFIG_I8K has multiple definitions:

Legacy /proc/i8k interface of Dell laptop SMM BIOS hwmon driver found in drivers/hwmon/Kconfig

The configuration item CONFIG_I8K:

Help text

This option enables the legacy /proc/i8k userspace interface of the dell-smm-hwmon driver. The character file /proc/i8k exposes the BIOS version, temperatures and allows control of fan speeds of some Dell laptops. Sometimes it also reports power and hotkey status.

This interface is required to run programs from the i8kutils package.

Say Y if you intend to run userspace programs that use this interface. Say N otherwise.

Dell i8k legacy laptop support found in arch/x86/Kconfig

The configuration item CONFIG_I8K:

Help text

This option enables legacy /proc/i8k userspace interface in hwmon dell-smm-hwmon driver. Character file /proc/i8k reports bios version, temperature and allows controlling fan speeds of Dell laptops via System Management Mode. For old Dell laptops (like Dell Inspiron 8000) it reports also power and hotkey status. For fan speed control is needed userspace package i8kutils.

Say Y if you intend to run this kernel on old Dell laptops or want to use userspace package i8kutils. Say N otherwise.

Dell laptop support found in arch/x86/Kconfig

The configuration item CONFIG_I8K:

Help text

This adds a driver to safely access the System Management Mode of the CPU on the Dell Inspiron 8000. The System Management Mode is used to read cpu temperature and cooling fan status and to control the fans on the I8K portables.

This driver has been tested only on the Inspiron 8000 but it may also work with other Dell laptops. You can force loading on other models by passing the parameter `force=1' to the module. Use at your own risk.

For information on utilities to make use of this driver see the I8K Linux utilities web site at: http://people.debian.org/~dz/i8k/
