The currently under-development 3.13 upstream kernel enables DPM by
default (without needing the radeon.dpm=1 boot parameter I mentioned
above) for Radeon HD 4000 through Radeon HD 7000 series graphics
processors but with some specific ASICs being excluded.

Note that although support for the upcoming Radeon HD 8000 series is
available in the 3.11 kernel (when used with libdrm 2.4.46, Mesa 9.2 and
xf86-video-ati 7.2.0), DPM for the Radeon HD 8000 series will arrive in
the 3.12 kernel as per http://lists.freedesktop.org/archives/dri-
Kernel 3.11.0-1.4 (based on the upstream 3.11-rc4 kernel) is now
available in Ubuntu 13.10 Saucy Salamander. Also, kernel 3.11.0-2.5 is
in Saucy-proposed, which is based on the upstream 3.11-rc5 kernel, which
has some bugfixes for the new DPM method.

I neglected to mention that to use the new power management feature on R700 and
newer hardware (other than APUs) requires installation of the latest AMD
graphics microcode (ucode) files to /lib/firmware/radeon
These are available at http://people.freedesktop.org/~agd5f/radeon_ucode/

See the blog post at http://www.botchco.com/agd5f/?p=57 for further
information.
Unlike the older dynpm method, the new DPM mehod works with multiple
monitors and there shouldn't be any flickering as the performance level
changes are handled by dedicated hardware rather than the driver.

been any activity in it recently. We were wondering if this is still an
issue? Can you try with the latest development release of Ubuntu? ISO CD
images are available from http://cdimage.ubuntu.com/releases/ .
