# build-nvidia-module.sh — compile NVIDIA proprietary driver modules for Debian 12
# build-nvidia-module.sh — compile NVIDIA kernel modules for Debian 12
#
# Downloads the official NVIDIA .run installer, extracts kernel modules and
# userspace tools (nvidia-smi, libnvidia-ml). Everything is proprietary NVIDIA.
# userspace tools (nvidia-smi, libnvidia-ml). Supports both:
# - open -> kernel-open/ sources from the .run installer
# - proprietary -> traditional proprietary kernel sources from the .run installer
#
# Output is cached in DIST_DIR/nvidia-<version>-<kver>/ so subsequent builds
# are instant unless NVIDIA_DRIVER_VERSION or kernel version changes.
