While speaking at the XDC2012 conference in Germany, Lucas Stach – a developer who has been playing around with open-source Tegra support, relayed a message from Andy Ritger that NVIDIA will be releasing the 2D documentation soon. One of the slides in the presentation even read “NVIDIA committed to open-source”.
The next version of the Tegra TRM (Technical Reference Manual) will provide developers with this no-strings-attached documentation covering the 2D engine and that this information should be effectively the same for the Tegra 2 and Tegra 3 generations notes Phoronix.
Another interesting thing to note here is that the unreleased GK110 also known as Tesla K20 supports Linux. This is not a common occurrence as it is hard to see hardware support added to Linux kernel even before the product is shipped officially.
Back in June, Linus criticized NVIDIA for its awful support of its Optimus technology in Linux. This criticism did manage to get NVIDIA to announce Optimus for Linux.
