We currently expose the same set of extensions on Ivy Bridge as we do on Sandy Bridge. If you have any specific inquiries, I'd be happy to answer them as best as I can. Also, if there are any extensions you'd like us to support, let us know. > For example > GL_ARB_robustness is supported but it seem like the > GetGraphicResetStatus() isn?t supported, is this tied down to hardware? We're planning on implementing that soon; Ian, Eric, and Ben have been working out the details. > I am also interested details on extension support that can be configure > such as support for s3tc texture compression which looks to be a DRI > config option. > > Douglas For now, the two configurable extensions are: - S3TC texture compression support To enable this, you need to install the libtxc_dxtn library. Mesa will then automatically detect the library and use it. No driconf options are necessary. - Floating point texture support To enable this, you need to build Mesa with: ./configure --enable-texture-float Enabling this also makes the driver expose OpenGL 3.0 rather than 2.1. Both of these are, unfortunately, encumbered by patents. (Otherwise, we'd just enable them all the time.) We still need to consult legal about this.
