In OpenBSD, you can use the pcictl command to see information about PCI devices on your system.
To see a list of all PCI devices, you can use the pcictl list command. This will display a list of all PCI devices, including their device names, vendors, and devices:
pcictl list
To see detailed information about a specific PCI device, you can use the pcictl list -v command followed by the device name. For example, to see detailed information about the PCI device pcib0, you can use the following command:
pcictl list -v pcib0
This will display detailed information about the PCI device, including its device and vendor IDs, class, subclass, and programming interface.
You can also use the pcictl command to configure PCI devices, such as enabling or disabling devices, setting bus mastering, or setting latency timers. Consult the pcictl man page for more information on these options.
Keep in mind that these are just general steps, and your specific configuration may vary depending on your system's setup. Consult the OpenBSD documentation for more detailed information.
