Originally posted by koolmanoncampus View PostI was actually talking to an AMD representative recently, they mentioned this exact functionality in future tools they plan to release.
He mentioned how they want to release tools to allow developers to better harness the GPU's computing power.
After posting I did some more reading round the gpgpu.org forums and found this thread
http://www.gpgpu.org/forums/viewtopic.php?t=4756
which raises some very interesting questions about the reliability and error rates on GPUs. I don't think for the moment I'd use the GPU for anything like compressing harddrive images, of course a few errors in a video compression probably won't mater but when the integrity of the data is more important than the speed of compression I'll stick with my CPUs and ECC registered RAM.

I just found www.gpgpu.org and their not mentioning this on the forums there, I guess specifications aren't going to make a big difference to the world of General-Purpose computation on Graphics Processing Units as they already have open APIs to use, though with closed compilers.
I wondered if we might get an open gpgpu framework and compiler, but I suspect it depends on how detailed the rest of the specks are and possibly how capable intels upcoming Larrabee GPUs are as to weather or not the results will be worth someones effort.

Processing with the GPU, speculation & questions.
What are the chances of the specks enabling us to use the GPU for more general purpose processing? I frequently backup and compress whole harddrives of data, or transcode MPEG2 video captured from my PVR-150 to Xvid, (soon H.264) is it going to be possible to use the GPU for some/which appropriate tasks?
The Folding@Home people only support R500 series GPUs because "The X1K boards were the first to support 32-bit precision and branching/looping on the ATI/AMD side of the world" and they strongly recommend the R580 / X1900 series, as it has 48 pixel shaders, presumably the same will be true of any future GPGPU efforts? What about R600 chips with their Unified Shaders?
What are the chances of H264 playback assistance, or a more general video decompression framework? What about on older (R300) hardware? Presumably this wouldn't require branching/looping and may well enable thousands of older PC's to perform as HD MythTV frontends.
I realise these questions are way ahead of them selves, and there's a LOT of work to do before we get to this point, but I'm just very excited at the prospect.
Thank you to all the developers for your effort on behalf of the FOSS community

Switching VTs reinitialises all of modesetting, and gives you a correct mode. Lid close events shuts down many things, and the lid open event than reenables everything like the bios thinks everything is being used, but this was of course altered by avivo or our radeonhd driver. Once we capture these events, this problem will be handled by the X server and "It Will Just Work" (famous last words).

Originally posted by chrisr View PostI have just tested the latest avivo driver from git and it still has the "screen is corrupt after you close the lid and then reopen it" bug. (The laptop's screen powers down when the lid closes, of course. However, it doesn't seem to reinitialize correctly afterwards.)

@Luc:
I got your point my friend...
I am sure you know better than me
Are you one of the people that develop that open driver said to be developed by Novell??

Let's hope that they will not stay there for a long time and release soon some "hotter" info...
Maybe they just prepare the new package of info right now, or discussing what info this will include...
Who knows?... Maybe Michael??
But I certainly have a good feeling! If policy changed completely about the approach of the community by ATI-AMD I believe we will see more and soon.
I am really tired of those nvidia guys bragging all the time about their linux advantage empire (full of bugs see Composite, Suspend, not even XvMC works bugless)...
