PCI_GET_CLASS(9) Hardware Interfaces PCI_GET_CLASS(9)NAME
pci_get_class - begin or continue searching for a PCI device by class
struct pci_dev * pci_get_class(unsigned int class, struct pci_dev * from);
search for a PCI device with this class designation
Previous PCI device found in search, or NULL for new search.
Iterates through the list of known PCI devices. If a PCI device is found with a matching class, the reference count to the device is
incremented and a pointer to its device structure is returned. Otherwise, NULL is returned. A new search is initiated by passing NULL as
the from argument. Otherwise if from is not NULL, searches continue from next device on the global list. The reference count for from is
always decremented if it is not NULL.

getconfig - get configuration information for the XFree86 server
getconfig [option ...]
getconfig is a programmatic interface that is used by the XFree86 server to get configuration information about video hardware when operat-
ing without an XF86Config file.
This implementation of getconfig is written in perl. It processes a prioritized and ordered list of rules supplied internally and from
meta-configuration files. The rules are in the form of perl expressions. getconfig writes to standard output the XF86Config-style config-
uration data specified by the last highest priority rule that evaluates to true. Information about the format of the meta-configuration
files can be found in the getconfig(5) manual page.
OPTIONS -I search-path
Specify the search path to use for meta-config files. search-path is a comma-separated list of directories to search. Each direc-
tory in the search path is searched for files with a .cfg suffix. Each such file is opened and checked for a valid signature
string. Rules are read from files with a valid signature string and appended to the list of rules to evaluate. If no search path
is specified, only the internally supplied configuration rules will be used.
-D Enable debugging output.
-V Print out the version information and exit.
Specify the XFree86 version in numeric (integer) form.
Specify the PCI subsystem ID of the video device.
Specify the PCI class of the video device.
Specify the PCI device ID of the video device.
Specify the PCI revision of the video device.
Specify the PCI subsystem vendor ID of the video device.
Specify the PCI vendor ID of the video device.
Specify the SBUS path of the video device.
.cfg files located in the search path. The search path typically specified by the XFree86 server is:
where <modulepath> is the XFree86 server's module search path.

The XFree86 automatic configuration support and the getconfig interface was written by David H. Dawes, with the support of X-Oz Technolo-
