An anonymous reader writes: It was revealed today during the annual X.Org Developers' Conference in Germany that NVIDIA will be publicly releasing Tegra graphics programming documentation. Initially this will cover their Tegra 2D engine but it's thought they might also be providing 3D engine documentation too. A slide shown at the conference says NVIDIA is committed to open-source. NVIDIA also allegedly has supplied documentation under NDA to one Nouveau developer and taken other covertly supportive steps. These actions come after NVIDIA has been notoriously unfriendly to open-source and months after Linus Torvalds pubilcly slammed the NVIDIA Linux support.
