System Hardware Driver Catalog is an installed kernel module explorer, pure-Python ELF .modinfo metadata viewer, and hardware modalias binding inspector for Linux systems. An independent Linux alternative inspired by desktop installed driver list utilities, it indexes /lib/modules kernel trees, built-in driver manifests, live /proc/modules state, and /sys/devices hardware modalias bindings.

Key Features:

• Kernel Driver Tree & Built-in Indexer: Catalogs loadable .ko modules, modules.dep dependencies, modules.builtin drivers, and modules.alias rules from host /lib/modules with automatic fallback to /sys/module and /sys/bus/*/drivers on custom kernels.
• Pure-Python ELF .modinfo Inspector: Reads .modinfo sections directly from uncompressed and compressed .ko binaries alongside modules.builtin.modinfo to display descriptions, authors, licenses, vermagic strings, dependencies, and module parameters.
• Hardware Modalias Correlation: Enumerates /sys/devices/**/modalias nodes across PCI, USB, ACPI, platform, NVMe, VirtIO, and VMBus buses and correlates each device with its active bound driver and matching modules.alias patterns.
• Subsystem Breakdown & Export: Summarizes driver counts and disk footprint by kernel subsystem and exports full inventories to CSV and JSON.
