After commit3382388d71("intel_rapl: abstract RAPL common code"), accessing to IOSF_MBI interface is done in the RAPL common code. Thus it is the CONFIG_INTEL_RAPL_CORE that has dependency of CONFIG_IOSF_MBI, while CONFIG_INTEL_RAPL_MSR does not. This problem was not exposed previously because all the previous RAPL common code users, aka, the RAPL MSR and MMIO I/F drivers, have CONFIG_IOSF_MBI selected. Fix the CONFIG_IOSF_MBI dependency in RAPL code. This also fixes a build time failure when the RAPL TPMI I/F driver is introduced without selecting CONFIG_IOSF_MBI. x86_64-linux-ld: vmlinux.o: in function `set_floor_freq_atom': intel_rapl_common.c:(.text+0x2dac9b8): undefined reference to `iosf_mbi_write' x86_64-linux-ld: intel_rapl_common.c:(.text+0x2daca66): undefined reference to `iosf_mbi_read' Reference to iosf_mbi.h is also removed from the RAPL MSR I/F driver.

Generic power capping sysfs interface configuration
menuconfig POWERCAP bool "Generic powercap sysfs driver" help The power capping sysfs interface allows kernel subsystems to expose power capping settings to user space in a consistent way. Usually, it consists of multiple control types that determine which settings may be exposed and power zones representing parts of the system that can be subject to power capping.
If you want this code to be compiled in, say Y here.

Client driver configurations go here.
config INTEL_RAPL_CORE tristate depends on PCI select IOSF_MBI
config INTEL_RAPL tristate "Intel RAPL Support via MSR Interface" depends on X86 && PCI select INTEL_RAPL_CORE help This enables support for the Intel Running Average Power Limit (RAPL) technology via MSR interface, which allows power limits to be enforced and monitored on modern Intel processors (Sandy Bridge and later).
In RAPL, the platform level settings are divided into domains for
fine grained control. These domains include processor package, DRAM
controller, CPU core (Power Plane 0), graphics uncore (Power Plane
1), etc.
config INTEL_RAPL_TPMI tristate "Intel RAPL Support via TPMI Interface" depends on X86 depends on INTEL_TPMI select INTEL_RAPL_CORE help This enables support for the Intel Running Average Power Limit (RAPL) technology via TPMI interface, which allows power limits to be enforced and monitored.
In RAPL, the platform level settings are divided into domains for
fine grained control. These domains include processor package, DRAM
controller, platform, etc.
config IDLE_INJECT bool "Idle injection framework" depends on CPU_IDLE default n help This enables support for the idle injection framework. It provides a way to force idle periods on a set of specified CPUs for power capping. Idle period can be injected synchronously on a set of specified CPUs or alternatively on a per CPU basis.
config ARM_SCMI_POWERCAP tristate "ARM SCMI Powercap driver" depends on ARM_SCMI_PROTOCOL help This enables support for the ARM Powercap based on ARM SCMI Powercap protocol.
ARM SCMI Powercap protocol allows power limits to be enforced
and monitored against the SCMI Powercap domains advertised as
available by the SCMI platform firmware.
When compiled as module it will be called arm_scmi_powercap.ko.
config DTPM bool "Power capping for Dynamic Thermal Power Management (EXPERIMENTAL)" depends on OF help This enables support for the power capping for the dynamic thermal power management userspace engine.
config DTPM_CPU bool "Add CPU power capping based on the energy model" depends on DTPM && ENERGY_MODEL help This enables support for CPU power limitation based on energy model.
config DTPM_DEVFREQ bool "Add device power capping based on the energy model" depends on DTPM && ENERGY_MODEL help This enables support for device power limitation based on energy model. endif
