Building a custom Red Hat Enterprise Linux kernel for NVIDIA DGX Spark

A step-by-step guide for building a custom RHEL 10 kernel and NVIDIA GPU driver from source to enable compatibility with the NVIDIA DGX Spark (GB10 Grace Blackwell Superchip) platform. Covers cloning the RHEL 10 kernel repo customized for GB10, installing build dependencies, compiling kernel RPMs (kernel-64k variant for ARM64), creating an RPM spec file for NVIDIA open-source kernel modules, building and installing the GPU driver RPM, installing CUDA via the NVIDIA repo and EPEL, and handling kernel updates via git reset. Intended as a Developer Preview workflow, not for production use.
