Hi
i've a one ATI/AMD RV630 card with kernel 3.11.5 and dpm enabled.
All works fine, but minor annoying problem. The dpm is choosing a power
state that isn't the best...
This is my card :
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV 630 XT AGP [Radeon HD 2600 XT AGP]
Here is the dpm output:

As you can see, the driver choose the performance profile, but
that one is limited to 400MHz, half of what this card can do. Of course i
want to be able jump the GPU to 800MHz. So is there any easy way
to choose the power state 2 instead of power state 1?
Also, when in using tvtime on a second head, the dpm jumps the gpu
clock to the max, yet i would like to use the middle speed. tvtime doesn't
require that much resources (even low can do it!). Yet i found no way to
force the middle power level. i can "echo high" and "echo low" to
power_dpm_force_performance_level but trying "mid", "middle" fail.
Is there any support to use the middle power level?
Thanks in advance.

Naturally the common people don't want war... but after all it is the
leaders of a country who determine the policy, and it is always a
simple matter to drag the people along, whether it is a democracy, or
a fascist dictatorship, or a parliament, or a communist dictatorship.
Voice or no voice, the people can always be brought to the bidding of
the leaders. That is easy. All you have to do is tell them they are
being attacked, and denounce the pacifists for lack of patriotism and
exposing the country to danger. It works the same in every country.
