# DarkForge Linux — NVIDIA Open Kernel Modules + Userspace
# RTX 5090 (Blackwell, GB202) requires nvidia-open 570.86.16+
# This package builds the open-source kernel modules and installs
# the proprietary userspace libraries (Vulkan ICD, OpenGL, EGL, GBM).
#
# NOTE: This is a complex multi-step package. The kernel modules are
# built against the running kernel headers, and the userspace libraries
# come from a separate download.
