NVIDIA/SUN cooperation to solve OpenGL Problems?

Java 2D
#1

Hi there!

I contacted the nvidia-bug support, namely the follwing person: aritger AT nvidia D0T com

They told me that sun has never contacted them because of driver problems or something like this. They even did not know that there is a huge performance problem.

If a Java2D-engineer working at SUN reads this, it would be cool if both could contact each other, I think SUN has a very bid administration-overhead many things take much time.

What problems exactly do you refer to?

See this thread:

and this bug report:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5073409

Thanks for asking NVIDIA!

I know, I have started the other thread.

I just posted this here so that maybe a java2d-developer can more easily see this, maybe they can contact each other and solve the outstanding problems in less time.

At least, it seems that with nvidia the property sun.java2d.opengl=true “works”… :wink:
With my ATI X800 Pro card, if i enable OpenGL the JVM crashes. But I have not yet analyzed the problem’s details…

Howdy,

Nvidia is a big company, so not everyone there is aware of customer complaints. We have contacts in the Linux driver team who we have had conversations with in the past, so this person is probably not aware of that. I will send another follow-up to them today specifically discussing this latest driver regression, and I will cc the above address to make sure the right people are aware. If there are any specific bug reports, etc, on Nvidia’s side that you could lobby for, I’ll let you guys know.

Maintaining relationships like this with the big driver makers (Nvidia, ATI) is crucial if we want to see driver quality (and performance) improve, so we will continue to work with them on these issues. Our ultimate goal is to get quality and performance to such a level that we can turn the OGL pipeline on by default in a future release.

Thanks,
Chris

Just a quick update… I was in touch with the Linux driver team at Nvidia today, and they are definitely aware of this issue. (A number of Java developers have contacted them about this problem in addition to my previous communication with them.) I will keep you updated as I hear progress on this issue from Nvidia. We are also working on sending them some updated automated regression tests so that they can prevent regressions like this in the future.

Thanks,
Chris

Thanks for keeping us updated Chris. Now this is good interaction between developers and Sun. :slight_smile:

  1. Someone reports something.
  2. Sun reacts and posts some thoughs and updates those with the results as well.
  3. The original poster feels satisfaction that he actually made a difference and will probably help out again.

Much to often interaction stops after that first bullet. Even though Sun is actually handling the problem, the original poster won’t know about it, get tiered of reporting stuff and then reports that his is getting tired of reporting stuff so that other potential posters get tired before they start. :wink:

:smiley:

Cheers,
Mikael

meh,

Any changes to the current driver won’t help me - unless they also fix the random freezes the latest drivers are giving my geforce2gts =/ (completely unrelated to Java ;))
