Dual Source Gpu Validation With Host Context

Combined execution of lspci (VGA and 3D controller extraction and device count) and nvidia-smi -q (product name extraction and non-empty count validation), together with kernel/architecture (uname -s -v -n -r -m) and uptime collection. This pattern reflects cross-validation of GPU presence using both PCI-level and NVIDIA driver-level queries, enriched with host system context.
