CONFIG_QCOM_CPR: QCOM Core Power Reduction (CPR) support

General informations

The Linux kernel configuration item CONFIG_QCOM_CPR has multiple definitions:

QCOM Core Power Reduction (CPR) support found in drivers/pmdomain/qcom/Kconfig

The configuration item CONFIG_QCOM_CPR:

• prompt: QCOM Core Power Reduction (CPR) support
• type: tristate
• depends on: CONFIG_ARCH_QCOM && CONFIG_HAS_IOMEM
• defined in drivers/pmdomain/qcom/Kconfig
• found in Linux kernels: 6.7–6.8, 6.9-rc+HEAD
• modules built: cpr, cpr, qcom-cpr

Help text

Say Y here to enable support for the CPR hardware found on Qualcomm SoCs like QCS404.

This driver populates CPU OPPs tables and makes adjustments to the tables based on feedback from the CPR hardware. If you want to do CPUfrequency scaling say Y here.

To compile this driver as a module, choose M here: the module will be called qcom-cpr
