They are not that large compared to the whole Nvidia driver (biggest file is 33K), but they might be copyrightable. The debian/copyright file of the Ubuntu package says: These files are firmware-like programs for initialising GPU context-switching. They were extracted from memory-mapped IO traces of the nvidia binary driver initialising the hardware. They were not generated by reverse-engineering the source code of the binary driver. . It is unclear to me whether these files are actually copyrightable. It seems that these programs are likely to be generated by the driver at runtime rather than being hand-written. The nouveau driver takes this approach for nv4x cards. If they are copyrightable, they should fall under the nvidia binary driver's licence, below. Followed by the text of the actual license. Since Nvidia does not distribute the files themselves and their license only allows redistribution of unmodified files, it seems that if the files are copyrightable they are also undistributable, but I'm no legal expert. > Do you know what happened about that? The latest thing I could find is a thread on the ubuntu-x list in February, starting at https://lists.ubuntu.com/archives/ubuntu-x/2010-February/000773.html. I don't know if any progress has been made since then. An alternative to the nouveau-firmware package would be to backport Marcin Kościelnicki's ctxprogs generator that is included in 2.6.34. It generates the GPU initialization data on the fly, so no firmware is needed. Sven -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
