It seems I spoke a bit too soon about everything working. I suspended my machine and now came back after a few hours and it seems the latest patches (well, I only could test the pm code in linus' tree of -34 up to now due to display corruptions so there's a lot of changes since then) in d-r-t killed suspend for me - the machine doesn't come back up and hardlocks.

I've been testing this code pretty hard this week and it's been solid. In addition to some fixes on top of what's in d-r-t, it also reworks the pm code to support two basic methods: 1. dynpm 2. profile You can select the methods via sysfs. Echo dynpm or profile to /sys/class/drm/card-0/device/power_method. The dynpm method dynamically changes the clocks based on the number of pending fences, so performance is ramped up when running GPU intensive apps, and ramped down when the GPU is idle. The reclocking is attemped during vertical blanking periods, but due to the timing of the reclocking functions, doesn't not always complete in the blanking period, which can lead to flicker in the display. Due to this, dynpm only works when a single head is active. Hi Alex, I just built a new version of d-r-t with your patches from yesterday applied on top and wanted to share my experience with you and the list (Radeon 2600XT mobile): Dynpm has gotten unusable for me as there's a noticeable effect on mouse movement (getting sluggish) The profile method exposes 4 profiles that can be selected from: 1. default 2. auto 3. low 4. high Select the profile by echoing the selected profile to /sys/class/drm/card-0/device/power_profile. the profile setting works but I can't check which clock speeds are set as I don't get any feedback (dmesg) anymore (Someone have any input on this?). The temps are unaffected whether I use the low or high profile, the only way I can tell that some things are working is by a 2000 fps-difference when running glxgears (something like 4000 on low and 6000 on high). I also attached a wattmeter to my my machine and the wattage alternates but I think I'm getting something along the lines of a 10W decrease in power consumption - it's very hard to tell, though. dynpm is a bit more effective and I even get lower temps (just under 50° compared to over 53 with the profile settings) but it's unusable right now as I already mentioned. All in all very nice work so far (this goes for all of you who've worked on radeon KMS PM!) - with the latest set of patches this is the first revision of KMS PM that actually works on my machine :) Klaus -- Klaus Doblmann B.A. - http://straightrazorguy.net - FSF member #7570 PGP-Key: http://www.doblmann.de/pgp_key.asc http://twitter.com/klausdoblmann A: Because it messes up the order in which people normally read text.

The power drops further when your monitors go off so that will save additional power when your machine is idle.

It built fine, I updated the firmware files as the Xor-Wiki suggests, but when I boot into the resulting kernel with dynpem on my screen goes all wonky, a portion on the right side is missing and I've got vertical lines running down the screen. Somehow I managed to look at dmesg and saw that the speed was being set correctly (it even set the lowest one available). When I tried "sudo echo 0 > /sys/class/drm/card0/device/dynpm" to see whether switching off dynpm would fix the "drunken" screen the system told me I was not permitted to access the file... I am attaching the syslog from the faulty boot in case it's of any help...
