[gentoo-user] coretemp and smartbatt drivers for lm_sensors

[gentoo-user] 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.

From any menu in make menuconfig, you can type '/' and enter a search string. 
Menuconfig will list all instances where it finds that string in item 
headings. coretemp is there.

smartbatt is found at CONFIG_ACPI_SBS, you can search for that string

and coretemp is CONFIG_SENSORS_CORETEMP

Also, if you are new to lm_sensors, beware that sensors-detect only
works on a subset of the supported sensor chipsets. On my computer,
for example, it detected the wrong chipsets which "sort of" worked
(gave wrong/incomplete readings). I had to manually tell it which
sensor chipset my motherboard uses.

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,

What CPU have you chosen in your kernel? Did you enable hardware
monitoring and expiremental modules?

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.

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.

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,
