[gentoo-laptop] coretemp and smartbatt drivers for lm_sensors

[gentoo-laptop] coretemp and smartbatt drivers for lm_sensors

[Valmor de Almeida]

Hello,

I am trying to configure lm_sensors and sensors-detect identified these 
two modules I don't know how to build.

smartbatt

coretemp

I tried many config options when rebuilding the kernel 2.6.27.12 
(vanilla-sources) but no luck in building the modules. Looking in the 
kernel sources doc I can see the coretemp module but can't find the 
corresponding config parameter in menuconfig. As for smartbatt, this is 
what is available in the source tree:


./drivers/acpi/.battery.o.cmd
./drivers/acpi/battery.c
./drivers/acpi/battery.o
./drivers/power/ds2760_battery.c
./drivers/power/palmtx_battery.c
./drivers/power/olpc_battery.c
./drivers/power/tosa_battery.c
./drivers/power/pmu_battery.c
./include/config/acpi/battery.h

Thanks for any help.

Coretemp is
CONFIG_SENSORS_CORETEMP=m

smartbatt is only ACPI I thought, not sensors.

The pictures help a lot. Under Hardware Monitoring Support I do not have 
the option

  Intel Core (2) Duo/Solo temperature sensor

in my menuconfig (vanilla-sources 2.6.27.12) which could enable 
CONFIG_CORETEMP. Interesting that the / search for
this config parameter gives me

  ┌───────────────────────────── Search Results 
──────────────────────────────┐
   │ Symbol: SENSORS_CORETEMP [=n] 

   │ Prompt: Intel Core (2) Duo/Solo temperature sensor 

   │   Defined at drivers/hwmon/Kconfig:351 

   │   Depends on: HWMON && X86 && EXPERIMENTAL 

   │   Location: 

   │     -> Device Drivers 

   │       -> Hardware Monitoring support (HWMON [=y])

Is there something else I need to enable to make the option visible? Or 
do I need to move to another kernel source.

Thanks,

I did not have

Prompt for development and/or incomplete code/drivers

selected under General Setup. Therefore missed options under Hardware 
Monitoring Support.

I chose Core2/newer Xeon because the help info says CPU family: 6. Not 
sure this is the correct choice. The /proc/cpuinfo follows below.

Thanks for your help.

Thanks for this search info. CORETEMP is there under the search but the 
enabling option is apparently not there; or I don't know how to make it 
appear. It looks like I am missing the option

Intel Core (2) Duo/Solo temperature sensor

in the Hardware Monitoring Support.

I've had that enabled to be compiled into the kernel. I will change to M 
and check whether the module is created.

Okay. I got i2c_i801.ko and coretemp.ko created and loaded in the 
kernel. The CONFIG_ACPI_SBS=m parameter creates two modules: sbs.ko and 
sbshc.ko; modprobe sbs loades both; hence no smartbatt. The relevant 
section from sensors-detect output is

Next adapter: SMBus I801 adapter at 18a0 (i2c-0)
Do you want to scan it? (YES/no/selectively): YES
Client found at address 0x0b
Probing for `Smart Battery'...                              Success!
     (confidence 5, driver `smartbatt')
Client found at address 0x19
Probing for `Analog Devices ADM1021'...                     No
Probing for `Analog Devices ADM1021A/ADM1023'...            No
Probing for `Maxim MAX1617'...                              No
Probing for `Maxim MAX1617A'...                             No
Probing for `Maxim MAX1668'...                              No
Probing for `Maxim MAX1805'...                              No

and it calls for smartbatt. Instead I loaded sbs.ko. The current output 
of sensors is

-> sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +56°C  (high =  +100°C)

Should the output show also info on the battery? Am I still missing 
something configuring ls_sensors?

Thanks,

Looking at the lm_sensors codebase, it looks like smartbatt might be
obsolete, having being replaced by sbs and sbshc - so instead of using
lm_sensors to interface with it, go and look in sysfs instead.
