Please see the latest ACPI specification for details on the objects. Using the details in the _TRT, the Passive Policy is responsible for limiting power and performance of components in response to a participant’s temperature rising above the platform defined _PSV trip point. The Passive Policy algorithm depends upon the platform thermal characteristics defined in the ACPI _TRT and _TRM objects. The Intel DPPM technology implements a series of Policies that can be used to better control platform behavior at thermal event trigger.

On a non-constrained system, Intel DPTF software works as a replacement for the typical thermal management.

By allowing an OEM design team to control platform skin and component temperatures, it is possible design for a “typical” rather than “worst case” power scenario while minimizing the impact to performance. While Intel DPPM is an implementation of the ACPI thermal model, Intel DPPM algorithms for thermal management are different than a OSPM thermal management implementation.ĭPPM is an intelligent closed-loop hardware and software solution for managing platform thermals in a constrained design. The thermal management technology is called Intel® Dynamic Power Performance Management (Intel® DPPM). Technologies that are currently supported as part of Intel DPTF are mainly focused on thermal management as specificied in the ACPI 5.0 specification. Please refer to the Documentation section for BIOS Reference Guide document (to be published soon). The BIOS Reference Guide provides implementation details for Intel DPTF and all the supported technologies. Intel DPTF relies on BIOS ACPI implementation on a specific device/system. As a container for multiple power/thermal technologies, Intel DPTF provides a coordinated approach for different policies to effect the hardware state of a device. Intel® Dynamic Platform and Thermal Framework (Intel® DPTF) is a platform level hardware/software solution for power and thermal management.
