The Linux Device Registry (devreg) is a kernel patch that adds a device database in XML format to the /proc filesystem. It collects all information about the system's physical devices, creates persistent device ids and provides them in the file /proc/devreg.
Devreg has three purposes: - collect all configuration data from drivers so the user can browse his hardware configuration. -allow an application to display all devices that provide a certain interface (for example all mice) so the user can chose one. -allow an application to find the device that the user has selected after a reboot or a hotplug action: the device files in /dev do not offer stable names, they depend on the order in that the devices have been plugged in or powered on.
Changes since last release (0.1.1): - converted file format to XML - bus-specific information from pci and usb added - fixed locking
The patch (for 2.4.3) can be found at http://www.tjansen.de/devreg/devreg-2.4.3-0.2.0.diff.gz To test it, apply the patch, select CONFIG_DEVFS_FS and CONFIG_DEVREG and compile. Note that the patch will break binary drivers.
Supported hardware in version 0.2.0: PCI subsystem, USB subsystem, most PCI sound cards, USB HID devices, USB hubs, USB printers
