[Dynamicpower-devel] DPM update

[Todd P. <tp...@mv...>]

DPM has been updated:

Core:

* Use trylock calls for policy spinlock to avoid sleeps in interrupt or
  preemption-off contexts.  Avoid warnings using Ingo's RT patches.

* Avoid bogus stats update for NO_STATE that could corrupt memory.

* Sanity check for constraint max >= min (from Amit Choudhary).

* Sync to kernel.org 2.6.11.

x86 arch:

* Update loops_per_jiffy and cpu_khz (and therefore /proc/cpuinfo) at
  frequency changes (from Napo'o).

OMAP arch:

(no changes)

See sourceforge.net/projects/dynamicpower/

By the way, presentations on DPM and several other embedded Linux
topics, notably an overview of Linux 2.6 Power Management by Nigel
Cunningham are at

(from a recent Consumer Electronics Linux Forum conference).
