There's plenty of ways to fudge the GPU when developing on nouveau by mistake, some of which can result in nouveau seriously spamming dmesg with fault errors. This can be somewhat annoying, as it can quickly overrun the message buffer (or your terminal emulator's buffer) and get rid of actually useful feedback from the driver. While working on my new atomic only MST branch, I ran into this issue a couple of times. So, let's fix this by adding nvkm_error_ratelimited(), and using it to ratelimit errors from faults. This should be fine for developers, since it's nearly always only the first few faults that we care about seeing. Plus, you can turn off rate limiting in the kernel if you really need to.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
