  • Firmware cache
  • Direct filesystem lookup
    • Firmware and initramfs
  • Fallback mechanisms
    • Justifying the firmware fallback mechanism
    • Types of fallback mechanisms
    • Firmware sysfs loading facility
      • firmware_fallback_sysfs
    • Firmware kobject uevent fallback mechanism
    • Firmware custom fallback mechanism
    • Firmware fallback timeout
  • Firmware lookup order
