hwinfo is a hardware detection and diagnostic utility that examines the devices connected to a Linux system. It identifies hardware components and provides detailed information that can help administrators troubleshoot problems, inspect device configuration and prepare technical support reports.
The program is developed by the openSUSE project and consists of the hwinfo command-line application and the libhd hardware probing library. The library is also used by YaST, openSUSE’s system administration and installation tool.
hwinfo can examine the complete hardware configuration or concentrate on selected types of devices. For example, users can investigate graphics adapters, disks, network interfaces or other components without having to examine an extensive system report.
The level of detail is configurable. A full hardware report provides information such as device identifiers, drivers, hardware resources and configuration status, while the short output mode offers a more manageable summary.
This is free and open source software.
Key Features
- Probe hardware components and generate detailed system information reports.
- Identify graphics cards, processors, storage devices, network interfaces and other hardware.
- Display PCI device identifiers, vendor information and associated drivers.
- Report device configuration, hardware resources and driver activation information.
- Restrict hardware detection to selected device classes such as disks or graphics adapters.
- Produce concise hardware summaries using the –short option.
- Examine individual devices using the –only option.
- Include detected RAID devices using –listmd.
- Record hardware probing information in a log file using –log.
- Save and retrieve selected device configuration information.
- Control probing behaviour using the hwprobe environment variable.
- Provide the libhd library for applications requiring hardware detection functionality.
