Hello,

I have an ATI Mobility Radeon HD 2400. I am using Linux 2.6.37. Currently,
dynpm does not down-clock the GPU for me. dmesg is filled with the following
messages:

[245199.552075] [drm:r600_pm_get_dynpm_state], Requested: e: 30000 m: 40000 p:
16
(about 10 messages / second)

I attach a script with all the necessary details.

Cristi.

Created an attachment (id=44245)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=44245)
Part of dmesg with power states

The problem is as follows. On r600, dynpm selects power state 1 and switches
between clock modes to upclock / downclock. One can see that power state 1 is a
performance power state, thus it does not include a low-power clock mode. In my
case, it would be preferable for dynpm to use power state 2. Ideally, users
should be able to select between low-power dynpm and performance dynpm.
