# Fixing compatibility with the RT (Real-Time) kernel

# 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.
patch -Np1 -i "${srcdir}/0003-nvidia-drm-modeset.patch"
# This patch edits the default values of the NVIDIA kernel module
# parameters, and makes the following changes:
#
# NVreg_UsePageAttributeTable=1 (Default 0) - Activating the better
# memory management method (PAT). The PAT method creates a partition type table
# at a specific address mapped inside the register and utilizes the memory architecture
# and instruction set more efficiently and faster.
# If your system can support this feature, it should improve CPU performance.
#
# NVreg_EnablePCIeGen3=1 (Default 0) - Enable PCIe Gen 3.x support.
# If the system supports this 8GT high speed bus then enable it with this module option flag.
# By default the Nvidia driver is set to use PCIe Gen 2.x for compatibility reasons.
#
# NVreg_InitializeSystemMemoryAllocations=0 (Default 1) - Disables
# clearing system memory allocation before using it for the GPU.
# Potentially improves performance, but at the cost of increased security risks.
# Write "options nvidia NVreg_InitializeSystemMemoryAllocations=1" in /etc/modprobe.d/nvidia.conf,
# if you want to return the default value.
#
# NVreg_EnableStreamMemOPs=1 (Default 0) - Activates the support for
# CUDA Stream Memory Operations in user-mode applications.
#
# If you want to learn more about the NVIDIA driver module parameters,
# you can go to the Gentoo Wiki or view the source code of the nv-reg.h file.
patch -Np1 -i "${srcdir}/0004-NVreg.patch"
# Sets the default power plan in preference to maximum
# performance. This is similar to the power plan settings in nvidia-
# settings. The advantage of this method is that it controls the power
# plan for each power source, i.e. the driver will be set for maximum
# performance when running from the mains and for the battery it
# will be set for optimal power savings. It also does not require nvidia-
# settings as a dependency and does not use it in any way.
