SLES 11 SP3 x86_64 kernel misses w83627ehf kernel driver to support hwmon features.

This document (7015650) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11 Service Pack 3 (SLES 11 SP3)

Situation

Many Intel based desktop and server boards are equipped with Winbond W83627DHG-P super I/O chips.
The W83627DHG-P super I/O chips provide support for hardware monitoring features such as for example Fan and Temperature sensors.

The Linux kernel driver to control these sensors is the w83627ehf.ko driver. Although the x86_64 kernel sources for this driver existed, the driver itself was not included in the x86_64 kernel, but was included with the x86 kernel.

As per the kernel release notes :
x86:   SUSE Linux Enterprise Server 11 SP3 for x86
x86_64:   SUSE Linux Enterprise Server 11 SP3 for AMD64 & Intel 64

Resolution

The w83627ehf.ko driver is added to the x86_64 kernel.

Cause

The w83627ehf.ko kernel driver was initially requested to be included with the x86 kernel only.
It was an oversight that it was not also added to x86_64.
