Hi, the community DPM project has been without a maintainer for a year
or so, although a couple of commercial OS offerings maintain their own
versions.  I don't know the current state of previous DPM-spin-off
community efforts such as "operating points" or the follow-on
refinements of interfaces for directly managing sets of arbitrary
platform power parameters.  The
https://lists.linux-foundation.org/mailman/listinfo/linux-pm list is
used to discuss such things with general PM folks.

Last I was involved with it, there was a distaste among certain
segments of the PM community for the interfaces proposed to manage
power for embedded systems (they didn't have much of a problem with
the ludicrously ugly interfaces for ACPI, but that's life as an
embedded Linux developer).  There was, however, solid support for some
ideas from a few influential developers.

The DPM project is kept alive to answer the occasional question and to
preserve it in case there's an interest in using this place to move
embedded PM forward somehow.
