+This is the open-source version of the kernel module needed by the
+proprietary binary nvidia driver.  It is provided as an alterative to
+the nvidia-kernel SBo script that builds the modules from the binary
+Nvidia package.  Note that it CANNOT be installed with the
+nvidia-kernel package, but you will still need the nvidia-driver
+package from SlackBuilds.org.
+
+To build the package for a kernel different from the running one,
+start the script setting the KERNEL variable as in
+    KERNEL=4.6.3 ./nvidia-open-kernel.SlackBuild
+
+A default config file is placed at 
+  /usr/share/X11/xorg.conf.d/10-nvidia.conf
+to make sure that X loads the nvidia module.  If you need to make
+changes, move that file to /etc/X11/xorg.conf.d/ and edit the copy.
+You do not need this file at all if you have a proper and complete
+xorg.conf.
+
+The xf86-video-nouveau-blacklist package from /extra is required.
+
+NOTES (quoted from the Nvidia driver README)
+
+"The open flavor of kernel modules supports Turing and later GPUs. The
+open kernel modules cannot support GPUs before Turing, because the open
+kernel modules depend on the GPU System Processor (GSP) first
+introduced in Turing.
+
+"Most features of the Linux GPU driver are supported with the open
+flavor of kernel modules, including CUDA, Vulkan, OpenGL, OptiX, and
+X11.  We eventually intend for the open kernel modules to replace the
+proprietary kernel modules.
+
+"The following features will only work with the open kernel modules
+flavor of the driver:
+
+   o NVIDIA Confidential Computing
+
+   o Magnum IO GPUDirect Storage (GDS)
+
+   o Heterogeneous Memory Management (HMM)
+
+   o CPU affinity for GPU fault handlers
+
+   o DMABUF support for CUDA allocations
+
+
+"The following features are not yet supported by the open kernel
+modules:
+
+   o G-Sync on notebooks
+
+   o Preserving video memory across power management events
+
+
+Use of the open kernel modules on GeForce and Workstation GPUs should
+be considered Beta quality in this release and no longer requires
+setting of the "NVreg_OpenRmEnableUnsupportedGpus" nvidia.ko kernel
+module parameter.  The open kernel modules are suitable for broad
+usage, and NVIDIA requests feedback on any issues encountered that are
+specific to them."
+
+After installation, you will need to reboot your computer for the
+changes to take effect.
+
+I am happy to report that ffmpeg hardware video encoding via h264_nvenc
+and hevc_nvenc now WORKS with this module.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
