NVIDIA Tegra 3 open source drivers add 3D support

It's a given that NVIDIA's Tegra 3 can handle 3D -- unless you've been crafting a fully open source project around the chip, at which point you've been stuck in a flat world. Fresh contributions from Avionic Design's Thierry Reding have brought that extra dimension back, albeit in limited form. His early patches for the Linux kernel enable support for 3D when using the Tegra Direct Rendering Manager driver. There's also a matching Gallium3D driver for us regular users, although it's still young: it can run reference 3D code as of a recent check, but can't produce visible imagery. While it may take some months before everything falls into place, the officially-backed work should make the (slightly aging) chip that much more useful beyond the realms of Android and Windows RT.
