Does libGLgn3.so for 945 GSE support openGL framebuffer object (FBO) extension?

BWei6 — Tue, 20 Jul 2010 14:15:10 GMT

Hello All,

We have a Linux Box with Atom N270 process with 945 GSE processor. Our linux supplier downloaded libGLgn3.so from IEGD package. However, libGLgn3.so does not seem to include GL_EXT_framebuffer_object extension. a. When I run glxinfo, it did not report this extension. b. grepping the binary file did not find the string either.Does libGLgn3.so (for 945 GSE) support GL_EXT_framebuffer_object extension? If not, what's the reason and any plan to include it in future release?

Thanks a lot,

Brian Wei

The following are outputs from glxinfo and grepping.

Re: Does libGLgn3.so for 945 GSE support openGL framebuffer object (FBO) extension?

One more related question:

There is second Intel linux driver (xf86-video-intel + Mesa3d),

http://intellinuxgraphics.org/index.html http://intellinuxgraphics.org/index.html" rel="nofollow">http://intellinuxgraphics.org/index.html

Can I use this driver combination for my N270 linux box? What's the difference betwen (xf86-video-intel + Mesa3d) and IEGD?

Thanks,

Brian Wei

I hope you installed the full IEGD driver that is available from http://www.intel.com\go\iegd http://www.intel.com\go\iegd" rel="nofollow">www.intel.com\go\iegd as you need ALL of the graphics driver to get full functionality. The configuration process does need to use a Windows (XP is best) capability so it is a bit inconvient for hardcore Linux users.

The other driver is what we call our "Open Source" driver. It provides the driver in a full source form HOWEVER, may not have full acceleration of 3D functions (or others) due to Intel I.P. concerns and GPL. IEGD uses quite a bit of "secret sauce" thus the hybrid source/binary release. IEGD implements a few more features (primarily for embedded applications and for OEMs). DO NOT MIX THEM as bad things WILL result.

The community boards on the Intel Linux site are a good place to get info about those particular products.

Hope this helps,

Kirk

Thanks for your reply. I did not configure the IEGD myself. I am an ender user working on application development. Our Linux board support supplier includes libGLgn3.so in the linux distribution.

Does you mean if we configure IEGD appropriately, framebuffer object extension may be included inside of libGLgn3.so?

Kirk_B_Intel — Wed, 21 Jul 2010 20:19:44 GMT

Are there any IEGD directories on your system? Does your xorg.conf have an IEGD section? It would be newaly impossible fo the library to operate if IEGD is not on the system as the graphics driver.

Unfortunately I do not see any reference to EXT_framebuffer_object in the PRD nor User's Guide so it is highly unlikely we support it. Not sure why our Gen 3 module (for 965) seems to have it per above.

Sorry I cannot porive better news. Kirk

hello kirk,

xorg.conf do have one section about IEGD. Rendering a texture image using libGLgn3.so is much faster than a mesa3d's openGL.so with purely software rendering. This indicates that libGLgn3.so is configured and worked correctly. However, in my application, I need to use frame buffer object. I read user's manual but did not find GL_EXT_framebuffer_object either. I just want to get a confirmation that libGLgn3.so does not support FBO. Thanks a lot for the info.
