    Re: kernel update and nvidia

    I've got Nvidia in all my machines, have used them for years, and frankly the constant hassles are becoming very tiresome. Fortunately this particular machine is 5.4. I think I'm going to start fishing for other GPU's.

    Re: kernel update and nvidia

    There is an active thread in the Ubuntu Development Version section of this forum on the Linux 3.9 kernel. I think those members would find this report useful as they test the 3.9 kernel.

    https://ubuntuforums.org/showthread.php?t=2448933

    This problem may become an issue during the development of Ubuntu 21.04. People installing the 21.04 release of Ubuntu may have problems and if they come here for solutions at least we know the cause of the problem.

    I do not understand why the Linux developers are so concerned with what Nvidia is doing. I am guessing from the little I have read about this that the Linux developers are concerned that proprietary code could enter into the kernel code by pretending to be GPL (General Public License) code and they are never going to allow that to happen as it would compromise Linux as GPL code. They are also concerned that Nvidia is not putting notices in the code as to who owns the copyright to the code. In this way Nvidia avoids blame for any bugs caused by their code.

    The issue is that the GPL covers derivative code: code that's derived from GPL code must be GPL'd. That's pretty much the point of the GPL. Nvidia (and others) don't want their code to be GPL'd, but they do want to interface with the kernel. The line between derivative code and original interface code is fuzzy at this level, and to actually determine whether a particular thing is derivative code or not requires going to court, which would be lengthy, expensive, and may vary by jurisdiction, and no one wants that. So, instead, the kernel devs have highlighted particular functions that, in their opinion, would make code derivative of kernel code: the GPL symbols. Stuff that uses normal kernel interfaces but doesn't use those functions can use whatever licence, but if it uses those particular functions then it's derivative code, and must be under the GPL. Everyone gets some clarity, and no one has to go to court to get judgment on GPL violations. People want to prevent deliberate GPL violations, but they want to avoid accidental GPL violations, too.

    In the comments of the Phoronix article several commenters note that only the UVM module is affected (CUDA and OpenCL). The display driver itself works fine (apparently).

    maybe they will at some point figure out that proprietary no longer make so much sense. if AMD can deliver, and if others actually help with improvements in their driver it might make them think.
    Read the easy to understand, lots of pics Ubuntu manual.
