All DPM community download software is made available via the sourceforge dynamicpower project file release area.

DPM core software is provided as a patch against the Linux 2.6 kernel source (the particular revision is given in the patch name). The patch implements DPM generic kernel support, and also provides kernel support for certain platforms with dynamic frequency and/or voltage scaling capabilities that are maintained in the kernel.org tree.

DPM does not compile operating point definitions (that is, collections of consistent settings for the various power parameters used for dynamic scaling on the platform) or policies into the kernel. Instead, this information is configured entirely from userspace. A script is typically supplied for at least one variant of each supported platform that sets up sample values for operating points and suggested power policies. Check the page for the particular platform of interest for scripts and documentation on that platform.

The platforms currently supported in Linux 2.6 are:

• Intel Centrino Enhanced Speedstep notebooks.
• TI OMAP platforms.

DPM for other embedded platforms is being ported from Linux 2.4 to 2.6 and is planned to be released in the near future.

IBM PowerPC 405LP for 2.4

The linuxppc_2_4_devel-pm BitKeeper tree is based on linuxppc_2_4_devel (last synced during 2.4.21) and includes core DPM and PowerPC 405LP Arctic III reference PDA platform support, plus a backport of the Linux Driver Model core (last synced at 2.5.70) and LDM callbacks for suspend/resume of Arctic III devices.
