CONFIG_INTEL_SPEED_SELECT_INTERFACE: Intel(R) Speed Select Technology interface drivers

General informations

The Linux kernel configuration item CONFIG_INTEL_SPEED_SELECT_INTERFACE has multiple definitions:

Intel(R) Speed Select Technology interface drivers found in drivers/platform/x86/intel/speed_select_if/Kconfig

The configuration item CONFIG_INTEL_SPEED_SELECT_INTERFACE:

• prompt: Intel(R) Speed Select Technology interface drivers
• type: tristate
• depends on: (none)
• defined in drivers/platform/x86/intel/speed_select_if/Kconfig
• found in Linux kernels: 5.15–5.19, 6.0–6.17, 6.18-rc+HEAD
• modules built: isst_if_mbox_msr, isst_if_mbox_msr

Help text

This config enables the Intel(R) Speed Select Technology interface drivers. The Intel(R) speed select technology features are non architectural and only supported on specific Xeon(R) servers. These drivers provide interface to directly communicate with hardware via MMIO and Mail boxes to enumerate and control all the speed select features.

Enable this config, if there is a need to enable and control the Intel(R) Speed Select Technology features from the user space.
