no config opt for k8temp in 3.6.11

no config opt for k8temp in 3.6.11

[Steven A. DuChene]

I have a few systems with AMD processors. One is a AMD Phenom II based system which uses a k10temp kernel module to get the CPU temperature. Another system has an Athlon64 processor which apparently is supposed to use a k8temp module to do the same thing. I have built a 3.6.11 kernel for each system that otherwise runs OpenSuSE-11.X. On the Phenom system the k10temp module is gets built and performs as expected. However on the Atlnon system even though I see the k8temp.c source file in the drivers/hwmon directory there does not seem to be a way in the kernel config files available from the 3.6.11 kernel sources to actually select that the k8temp module should be built. Is this some oversight in the makeup of the kernel config files or am I missing something obvious?

Please CC me on replies as I am not normally subscribed to the kernel mailing list.

Thanks

That's strange, I can select all the AMD power drivers on 3.6.11:

$ grep -E "^CONFIG_SENSORS" .config
CONFIG_SENSORS_K8TEMP=m
CONFIG_SENSORS_K10TEMP=m
CONFIG_SENSORS_FAM15H_POWER=m

Can you do 'make mrproper' and try regenerating your config? But
remember, mrproper will remove your .config so you might want to save
that upfront in case you need it.

HTH.

When I do a grep for K8 in my .config file all I get is the following:

> grep -i k8 /usr/local/hugedisk/src/linux-3.6.11/.config
CONFIG_MK8=y
CONFIG_X86_POWERNOW_K8=y

When I try your grep command I get:

> grep -E "^CONFIG_SENSORS" /usr/local/hugedisk/src/linux-3.6.11/.config|grep K
CONFIG_SENSORS_K10TEMP=m

I will try doing a make mrproper and see if anything changes.

Thanks for the reply.
