Hi, make oldconfig asks me here on a x86 machine about this below and it looks like this should depend on some P8 config item so that it doesn't show on other architectures. Right? Thx. CONFIG_SENSORS_OCC_P8_I2C: This option enables support for monitoring sensors provided by the On-Chip Controller (OCC) on a POWER8 processor. However, this driver can only run on a baseboard management controller (BMC) connected to the P8, not the POWER processor itself. Communications with the OCC are established through I2C bus. This driver can also be built as a module. If so, the module will be called occ-p8-hwmon. Symbol: SENSORS_OCC_P8_I2C [=n] Type : tristate Defined at drivers/hwmon/occ/Kconfig:6 Prompt: POWER8 OCC through I2C Depends on: HWMON [=y] && I2C [=y] Location: -> Device Drivers -> Hardware Monitoring support (HWMON [=y]) -> POWER8 OCC through I2C (SENSORS_OCC_P8_I2C [=n]) Selects: SENSORS_OCC [=n] -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
