More Radeon Power Management Improvements

[agd5f]

Do you know of an option somewhere to avoid this?

with mesa from git set:
vblank_mode=0
do disable vsync. See this bug for related info:

Thanks, but I couldn't make it to work. It won't load the freshly compiled 3D driver for whatever reason >_<

Next time I may have more luck.

Is it/will it be possible somehow for the application to request a graphics mode without vsync?

My FirePro v8750 still shits 60 Watt more power in Linux desktop than in Win 7 desktop. Remind you that this card doesn't even clock down in idle (designed as such). So I guess clock gating / power gating must not working at all under Linux

As has been stated before, see this message for more on the current pm state:

You'll need to either enable dynpm mode or manually select a power state.

I am currently running Ubuntu 10.04 with stock kernel 2.6.34.

Which kernel version has your mentioned functionality? It would be nice to test it out.

I can't seem to find power_method in my sysfs directory.
Any idea what could be the reason?

Yes:

In power subdirectory there's only a file called wakeup.
