Your tasked with updating both NVIDIA GPU drivers and DOCA drivers on a set of...

NVIDIA AI infrastructure relies on a tightly coupled stack involving the GPU driver and the DOCA (Data Center Infrastructure-on-a-Chip Architecture) drivers, which include the OFED stack for InfiniBand. When upgrading from an older version, " residue " from previous installations or custom kernel modules can cause version mismatches or symbol errors, preventing the new drivers from loading. The " 100% verified " best practice is to perform a clean installation. This involves completely uninstalling the existing drivers (using apt-get purge or the .run file ' s --uninstall flag) and ensuring that kernel modules are removed from memory. This prevents conflict between the legacy nvidia.ko and the new version. Once the system is " clean, " the new DOCA and GPU drivers can be installed as a matched set, ensuring that features like GPUDirect RDMA function correctly without being hindered by legacy configuration files.
