How to change radeon power state

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:

[   12.362972] 	status: r 



	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.

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.

We'll probably need to add a quirk for your card.  Can you send me the
output of lspci -vnn for the GPU?

	Please note that the original card firmware had all powerstates
the same, i had used rbe (http://www.techpowerup.com/rbe/) to change then
to the current frequencies. In that app, the powerstate 1 is called
battery and the powerstate 2 is called performance. 

	I can switch the two and reflash, but to me seems logic that one
can manually choose what powerstate to use if needed, just like the 
powerlevels (excluding the middle powerlevel problem)

	Here is the output:

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI RV 630 XT AGP [Radeon HD 2600 XT AGP] [1002:9586] (prog-if 00 [VGA controller])
	Subsystem: PC Partner Limited Device [174b:0028]
	Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 16
	Memory at e0000000 (32-bit, prefetchable) [size=256M]
	I/O ports at e000 [size=256]
	Memory at fbf00000 (32-bit, non-prefetchable) [size=64K]
	Expansion ROM at fbe00000 [disabled] [size=128K]
	Capabilities: [50] Power Management version 3
	Capabilities: [58] AGP version 3.0
	Kernel driver in use: radeon

Thanks in advance.

You'll need to fix the power state to be flagged as performance.

	Ok, i didn't do that already because the different powerstate names 
that the rbe and the dpm read from the firmware (battery and performance vs
performance and "none" for powerstate 1 and 2 respectively ). Please note 
that i can change the powerstate values, but not their names.

	Can this be a bug in reading the powerstates? if not, i will reflash
the firmware.

	Also, how about que question about the middle power level? how to 
force it? low and high works, but mid or middle do not.

Thanks again
