commit 1cb9e2ef66d53b020842b18762e30d0eb4384de8 upstream. We have a lurking bug where Fragment Shader Helper Invocations can't load from memory. But this is actually required in OpenGL and is causing random hangs or failures in random shaders. It is unknown how widespread this issue is, but shaders hitting this can end up with infinite loops. We enable those only on all Kepler and newer GPUs where we use our own Firmware. Nvidia's firmware provides a way to set a kernelspace controlled list of mmio registers in the gr space from push buffers via MME macros. v2: drop code for gm200 and newer.

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.
