Description Roman Šmakal 2008-12-24 16:57:17 UTC
Hello there,
i am HD2600 mobility user and there are problems with overheating, when i use kaffeine to play media. I am not sure, if it is CPU or GPU related (notebook gets really hot on two places, so maybe both) - CPU usage is on 100% for one core.

System:
Toshiba A200 1SJ
Core2 Duo 1,6GHz,
Radeon HD2600 Mobility
2GB RAM

It's probably the CPU since we don't actually use any of the hw acceleration features on the GPU yet.

Well, i dont think its only CPU, because only one core is on 100% and my notebook doesnt overheating while i am using both cores on 100% (compilation of program for example). But what i know is it is really driver-related, because it is okay with fglrx

There's no acceleration for your GPU with the open-source drivers, so the CPU has to do all the video decoding, which is why it's overheating.

Not sure if this is "invalid," or "not a bug."

I've never talked about decoding - video decoding does not utilizes CPU so much and the overheating is really big (playing the movie with about 25 minutes causes that GPU is really overheating my system and slowing down FPS). Think to know is that it is happening only in kaffeine, mplayer works a bit better. I gonna try changing video outputs and tell you if it helped.
But what i DONT think is, that it is not a bug or invalid - yep, R600 have just initial support, but this is really critical problem, because some of laptops could be destroyed with overheating, its a bit dangerous. So think to say is - this is a bug and should stay opened until some fix gonna be found.

I did some research and now cant i be sure, that it is CPU or GPU. So i am marking this as invalid and telling you sorry about bad bugreport. I did what i can, but i didnt had dissasembled my laptop, so i cant be sure... Sorry then.

It could also be that your driver is too old to support PowerPlay, as I
don't _think_ support for that is included in any release.  It is,
however, in git master, so I guess 6.10 or 7.0 or whatever should give
you a significantly cooler GPU overall.
