I mean, why doesn't AMD simply have somebody going over the code of catalyst, deleting everything patented or "secret" and release the nonfunctional rest? Could still be helpful for low level stuff like power saving and communicating properly with the hardware...

In economic you deal with the future not with the past or with the presence.
this means the grow factor is more important than the market-share.
right now linux do have 3,5%(2%andorid) market share (source: wikipedia.org) and a grow rate of 40% every 6 month (source: Net Applications ).
and market analyst found out that nearly 80% of all companys wana grow there opensource usage to lower costs. (source: linux foundation market survey)
just do the mathematics: calculate grow rate 40% every 6 month on the market share 1,5%
this numbers prove : Microsoft is allready death

I think their last CEO was fired basically for the decision to sell of their mobile graphics division to Quallcom. It will take them some time to recover from that decision.

AMD looses some very important point here. Now with not optimal FOSS driver, and since APU initiative, they loose not only GPU sale, but CPU and chipset sales.
For people that don't care, there is always some Linux geek whom they consult(or just the salesman), and he will tell them "Yes do choose intel, they are flawless"
I like AMD, but if Trinity fails, I would go intel way.
On the topic...can't this PCI-E 2.0 setting being enabled at least for the APUs(Brazos,Llano)? They have internal PCI-E link, so no motherboard involved.

and the Trinity opensource announcements come tomorrow or the day after tomorrow.
i think they will grow the opensource team and focus on openCL and video acceleration.
but in fakt the biggest impact will not be in the "trinity" generation because its a VLIW based gpu architecture like the hd6970.
the successor of trinity will be the one with the greatest open-source impact.
because then its a hd7970 based gpu.
This time you actually make sense! For the following reason:
AMD will switch to FSA (Fusion Systems Architecture), which they renamed yesterday or today to HSA (Heterogeneuos Systems Architecture). This is their new intruction set that is open, meaning that anyone can support it. It's better than Intel's, because they let all supporters to have a voice in it's developement.
Here comes the rational for the renaming: Fusion is already accociated with AMD which is bad for other backers, e.g. ARM. So they simply changed it -- the hardware will come in a few years anyways, so no problem.
Now, here's the big news: HSA is an ISA that is an extension of OpenCL.
So your OpenCL code will run pretty efficiently on these systems.
The catch is that the architectures for the CPU and GPU part will be fully integrated, will have the same address space, etc. Hence fglrx would be needed for your CPU as well!
Hordes of Linux users may not give a crap about fglrx today but everybody will be pissed if they can't even boot a live CD without a blob!
Can you see now why they invest in OpenCL and why would they further increase that?
+1: HPC industry wouldn't like problematic binary blobs, especially for CPUs. Don't forget that the market share of Linux is about 90% there.
Edit:
+2: Have you noticed that there's _no_ patent issues whatsoever with OpenCL?
/me hoping for the rise of Mesa in the following years!Last edited by HokTar; 21 January 2012, 06:39 AM.

AMD has a grand vision for software and physical integration of CPUs and GPUs. The first Fusion generation focused on time to market, but created a solid foundation. Llano is a surprisingly attractive mid-range and value notebook product, due to the vastly enhanced power management. Future Fusion products will upgrade the CPU, GPU and media hardware and move towards a more tightly integrated computing model.
