Everything I read online seems to relate to Ubuntu. How can I enable Radeon DPM support? My tumbleweed install is very up to date. My hardware is quite supported. But when I run Linux it runs hotter then when I (rarely) boot into Win 7. I’m not a heavy gamer, so whatever performance bumps the DPM support brings are unimportant. For just running KDE with full compositing and all it feels snappy with the open source driver. But energy savings do matter to me.
OpenSuSE 12.3 > Tumbleweed
Toshiba Satellite L645D
Dual core AMD Turion II P540 (2.4 ghz, 64-bit)
8 gigs of RAM
Integrated Radeon 6 series part
960 gb Crucial SSD
BTRFS awesomeness
kernel 3.11.0-27
If any further info is needed, I shall provide.
I added radeon.dpm=1 to the kernel line in /boot/grub/menu.lst.
This works for kernel 3.11.6-1.gf7498bf on openSUSE 12.3 and
gkrellm reports a temperature reduction for radeon by over 10 C.
As you’ve discovered, its currently not enabled by default (this will change in future). Right now (as already mentioned) you add the kernel boot parameter … use Yast bootloader module to do this. … A firmware is also required, however, it *should *have been included with your kernel. You can use
dmesg |grep "dpm initialized"
to confirm

dpm only impacts performance for those adapters (typically those of the APUs and SI arch) which previously would boot with a low default clock, as enabling dpm allows them to reclock to higher speeds.
note that this would be specific only to legacy grub … grub2 is different .

Notice that Tumbleweed is “different”. You should have asked in the
Tmbleweed forum here. You still can ask a moderator to move your post,
using the triangle report button.
