About:
Pciutils is a collection of utilities for inspecting and manipulating devices connected to the PCI bus. It provides essential tools like lspci and setpci for listing devices and configuring their parameters. This suite is vital for system administrators and developers managing hardware resources and debugging driver issues.
Key Features:
  • lspci for listing all PCI devices
  • setpci for configuring PCI device parameters
  • pcimodules for listing loaded kernel modules
  • Verbose hardware decoding capabilities
Use Cases:
  • Debugging hardware detection issues during system boot
  • Verifying PCI device configurations and resource allocation
  • Scripting hardware inventory for system audits
Alternatives:
  • lshw – lshw provides a broader overview of all hardware, whereas pciutils focuses specifically on the PCI bus.
  • sysfs – Sysfs provides raw kernel data; pciutils offers a user-friendly CLI interface to parse and manipulate that data.
