+Subject: [PATCH] NVreg Improvements
+
+This patch edits the default values of the NVIDIA kernel module
+parameters, and makes the following changes:
+
+NVreg_UsePageAttributeTable=1 (Default 0) - Activating the better
+memory management method (PAT). The PAT method creates a partition type table
+at a specific address mapped inside the register and utilizes the memory architecture
+and instruction set more efficiently and faster.
+If your system can support this feature, it should improve CPU performance.
+
+NVreg_EnablePCIeGen3=1 (Default 0) - Enable PCIe Gen 3.x support.
+If your graphics card supports PCIe 3.x, this driver module option
+can active the high-speed 8 GT bus.
+By default the Nvidia driver is set to use PCIe Gen 2.x for compatibility reasons.
+
+NVreg_InitializeSystemMemoryAllocations=0 (Default 1) - Disables
+clearing system memory allocation before using it for the GPU.
+Potentially improves performance, but at the cost of increased security risks.
+Write "options nvidia NVreg_InitializeSystemMemoryAllocations=1" in /etc/modprobe.d/nvidia.conf,
+if you want to return the default value.
+Note: It is possible to use more video memory (?)
+
+NVreg_EnableStreamMemOPs=1 (Default 0) - Activates the support for
+CUDA Stream Memory Operations in user-mode applications.
+
+If you want to learn more about the NVIDIA driver module parameters,
+you can go to the Gentoo Wiki page or view the source code of the nv-reg.h file.
