How To Setup Radeon DPM On Ubuntu Linux

[mrugiero]

So let me get this straight, DPM isn't for Sea Islands/RHD 8000 yet?

I did notice some improvements (around 15-25% longer battery life), and I *think* mine (Aruba + Tahiti? glxinfo informs Aruba but the kernel asked me for Tahiti firmware on boot, too) is Sea Islands.

That's promising. I'm specifically looking for support with the Mars XT chipset (Radeon 8770M) as that's the card in the laptop I just bought. By the way, does the kernel/mesa even support the 8000M (Solar System) series yet?

Aren't the laptop 8k series all 7k rebrands?

The HD 8000Ms are rebrands... and it sounds like your card is actually an HD 6000M.

Not yet. The code wasn't ready when we released the initial Sea Islands support. I've since gotten it working and it should show up in the next kernel.

[agd5f]

Tahiti and Mars are Southern Islands family and they are already supported (including DPM).

Ah, thanks for the clarification!
Also, if I may digress a little here, I really appreciate the hard work you and others do to bring open-source Radeon support to everyone. God knows what it would be like if using Catalyst was the only option! Keep up the good work!

You don't need any new ucode for power management on that chip, but you still need the ucode for the CP, RLC, and UVD.

The microcode for aruba uvd doesn't exist...

So let me get this straight. Is the Radeon 7870 supported? (As there is a post that says "Not yet", and right below that "yeah it is".)
(Pitcairn - says GPU-Z)

Because I installed a new kernel (rc4 from Kernel.org) and set up everything, but I still can't get it working.
I tried the 3.11-fixes first of course.

The problem (as you can see this adds up 2 minutes to the boot time):

I did update the ucode from the Phoronix link. Both files are present/updated that the error mentions.

if you have all files .bin in /lib/firmware/radeon try this:

man update-initramfs

you need TAHITI_uvd.bin file too.
