For the ones of you who haven’t read Phoronix lately – Michael is running a survey about Intel Linux Graphics drivers for the past few days.
So far it got 10 pages of amazingly interesting comments (which I was trying to answer as time and my fingertips permitted). 95 comments as of now to be fair (sorry, 96 already – my bad 
). Make sure to check it out.
In the end, I’ll try to summarize all my replies in the thread here. But it will be a long read by the looks of it.
You wrote : “my opinion is – let Gallium 3D and traditional MESA co-exist. Their evolution only benefits the progress of open-source as a whole. When Mesa advances, Gallium has a possibility of taking a leap ahead. And vice-versa, when Gallium makes progress, Mesa needs to catch up again. So in the end, everyone wins.”
Some work is being done to bring OpenCL to Gallium3D.
But you wrote : “there are no plans to provide opencl support in the open-source drivers at the moment”
Therefore it seems that not always everyone wins :-/
Since i don’t play 3D games, OpenGL ES 2.X is enough for me and Intel drivers already provide it, thank you. VA-API is another thing that i desire, and Intel is behind it, thank you too. But whereas OpenCL is the 3rd thing that may be interesting for me (GIMP may use it soon for some stuff for instance), ntel have plan for it, too bad :-/
Another point : since Intel have made great progress with its graphic part (better performance, less consumption with Gen 5, 6 and 7), is PowerVR technology still needed ? You should give it up for home-made technologies now
@antistress – about OpenCL – my personal opinion is that the issue is not a technical problem, but marketing or commercial one. Just like with PowerVR – I personally think that Gen graphics should replace them, but I am no marketing nor sales guy.
However, I am just a developer, so I cannot comment nor influence on company decisions
.
Anyway, many thanks for taking the time to answer questions
Reading that recent pice of news http://www.phoronix.com/scan.php?page=news_item&px=MTA0NTk :
GEGL is about to become the Gstreamer for pictures, and more and more applications will use it (GIMP, darktable ) and therefore OpenCL will spread without support from Intel :-/
@eugeni : hurra ! “Intel Is Planning To Drop PowerVR Graphics” http://www.phoronix.com/scan.php?page=news_item&px=MTA1NDU You don’t even have to comment
dartktable 1.0 is finally out and provides OpenCL support…
