[solvedish] Radeon ATI Power Management not working on Dual-Head

EDIT: This is only when I'm running dual-headed. Confirmed upstream bug fixed by running either one head or switching to catalyst drivers.

Hey,

Not sure what's changed by my ATI Radeon 5950is running hot and frequencies are not changing.

Here's what I've done

# echo low > /sys/class/drm/card0/device/power_profile
# echo profile > /sys/class/drm/card0/device/power_method 

cat /sys/kernel/debug/dri/0/radeon_pm_info
default engine clock: 800000 kHz
current engine clock: 799940 kHz
default memory clock: 1250000 kHz
current memory clock: 1250000 kHz

# echo dynpm > /sys/class/drm/card0/device/power_method 

cat /sys/kernel/debug/dri/0/radeon_pm_info
default engine clock: 800000 kHz
current engine clock: 799940 kHz
default memory clock: 1250000 kHz
current memory clock: 1250000 kHz

# sensors
radeon-pci-0100
Adapter: PCI adapter
temp1:        +62.0 C

Not running anything graphic intensive. KMS seems to be loaded

It will not work properly until AMD provides all the Documents so the devs can write the code. They (AMD) had done some things but they cannot release them.

You cannot do anything about it.

Not sure I understand? I'm using documented features here: http://www.x.org/wiki/RadeonFeature and from the ATI Wiki. I'm not using proprietary drivers.

Its not working well. And you can only do PM manually. (ie set low mid high etc)

There is not much you can do actually so leave it as it is. Its a known problematic area of the FOSS driver. If you want proper PM use the blob.

Well, I definitely don't want to be running at full power and 65 degrees for hours on end. I tried manually setting the low profile but the clocks stayed the same. Looks like I'll file a bug report and switch to catalyst for now.

Thanks

Just an FYI, Confirmed upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=42854
