# Fixing compatibility with the RT (Real-Time) kernel
patch -Np1 -i "${srcdir}/linux-rt.patch"
# This patch edits the default values of the NVIDIA kernel module parameters,
# and makes the following changes:
#
# NVreg_UsePageAttributeTable=1 (Default 0) - Activating the better memory management method (PAT).
# The PAT method creates a partition type table at a specific address mapped inside the register
# and utilizes the memory architecture and instruction set more efficiently and faster.
# If your system can support this feature, it should improve CPU performance.
#
# NVreg_EnablePCIeGen3=1 (Default 0) - Enable PCIe Gen 3.x support.
# If the system supports this 8GT high speed bus then enable it with this module option flag.
# By default the Nvidia driver is set to use PCIe Gen 2.x for compatibility reasons.
#
# NVreg_InitializeSystemMemoryAllocations=0 (Default 1) - Disables clearing system memory allocation
# before using it for the GPU. Potentially improves performance, but at the cost of increased security risks.
# Write "options nvidia NVreg_InitializeSystemMemoryAllocations=1" in /etc/modprobe.d/nvidia.conf,
# if you want to return the default value.
#
# NVreg_EnableStreamMemOPs=1 (Default 0) - Activates the support for CUDA Stream Memory Operations in user-mode applications.
# Note: May be disabled in future versions.
#
# If you want to learn more about the NVIDIA driver module parameters,
# you can go to the Gentoo Wiki or view the source code of the nv-reg.h file.
patch -Np1 -i "${srcdir}/NVreg.patch"
# Enable nvidia-drm.modeset=1 (DRM KMS) by default.
# This is necessary for NVIDIA PRIME to work correctly.
# Note: May cause problems with scaling in console mode.
