.TH getconfig __filemansuffix__ __vendorversion__
.SH NAME
getconfig - meta configuration files for getconfig(1)
.SH SYNOPSIS
.B \(**.cfg
.SH DESCRIPTION
.B getconfig
is a programmatic interface that is used by the
.B __xservername__
server to get configuration information about video hardware when
operating without an
.B __xconfigfile__
file.
.PP
This implementation of
.B getconfig
is written in perl. It processes rules from meta-configuration files.
All meta-configuration files have a
.I .cfg
suffix.
.PP
Lines starting with a pound-sign (#) are comments, and are ignored.
Blank lines that consist only of white space are also treated as comments
and ignored.
.PP
The first non-comment line must be a signature string followed by
the file format version number. The signature string is
.PP
.RS 4
.nf
"Xorg getconfig rules file.\ \ Version: "
.fi
.RE
.PP
The currently defined version is "1.0". Files that do not have the
correct signature string are ignored.
.PP
The remaining non-comment lines define rules. The start of a new rule
is indicated by a line with no leading white space. Subsequent lines
making up a rule must be indented with white space. Logical lines within
a rule may be split over multiple physical lines by using the usual
continuation convention ('\e' at the end of the line). The first logical
line of each rule is a perl expression. It may be any valid perl
expression whose evaluated (with 'eval') result may be used as the
argument to a perl 'if' statement. The second logical line should be
the name of the __xservername__ video driver to use when the rule is true, and
subsequent logical lines of each rule, if present, are additional
configuration output for the video device's
.B __xconfigfile__
.B Device
section. The driver name and additional lines of configuration information
are written to standard output when the rule is chosen as the successful
rule.
.PP
Pseudo rules consisting of perl expressions may be present in the file
for the purpose of defining custom perl variables or setting the weight
to use for the following rules. Pseudo rules are rules that consist of
a single logical line only, and the are never candidates themselves for the
successful rule.
.PP
Several perl variables are pre-defined, and may be used within rules.
They include:
.PP
.RS 4
.nf
.BR "$vendor " "PCI vendor ID"
.BR "$device " "PCI device ID"
.BR "$revision " "PCI revision ID"
.BR "$subsys " "PCI subsystem ID"
.BR "$subsysVendor " "PCI subsystem vendor ID"
.BR "$class " "PCI class"
.BR "$XorgVersion " "Xorg version, as a 'v' string"
.BR "$XorgVersionNumeric " "Xorg numeric version"
.BR "$XorgVersionMajor " "Xorg major version"
.BR "$XorgVersionMinor " "Xorg minor version"
.BR "$XorgVersionPatch " "Xorg patch version"
.BR "$XorgVersionSnap " "Xorg snap version"
.BR "$weight " "current rule weight"
.fi
.RE
.PP
The
.B $weight
variable determines the weight of the rules as they are processed. The
weight for subsequent rules may be set with a pseudo rule that sets or
changes the value of
.BR $weight .
The default weight, and the weight used for built-in rules is 500. The
meta-configuration files are processed in an unpredictable order. The
weighting of the rules is used to determine their relative priority
.PP
After processing all of the rules, both built-in and those read from
the meta-configuration files, the
.B getconfig
program chooses as the successful rule the last and highest weighted
rule that evaluates to true.
.SH FILES
.I .cfg
files located in the search path. The search path typically specified
by the
.B __xservername__
server is:
.PP

.I /etc/X11

.I <modulepath>
.I __projectroot__/lib/X11/getconfig
.fi
.RE
.PP
where
.I <modulepath>
is the
.B __xservername__
server's module search path.
.PP
.TP 30
.I __projectroot__/lib/X11/getconfig/xorg.cfg
Default rules file that gets installed. This file doesn't contain any
rules by default.
.TP 30

appear in rules files.

The __xservername__ automatic configuration support and the

interface was written by David H. Dawes, with the support of X-Oz
Technologies for XFree86.

.TH getconfig 1 __vendorversion__
.SH NAME
getconfig - get configuration information for the __xservername__ server
.SH SYNOPSIS
.B getconfig
.RI [ option
.IR ... ]
.SH DESCRIPTION
.B getconfig
is a programmatic interface that is used by the
.B __xservername__
server to get configuration information about video hardware when
operating without an
.B __xconfigfile__
file.
.PP
This implementation of
.B 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.
.B getconfig
writes to standard output the __xconfigfile__-style configuration 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(__filemansuffix__) manual page.
.SH OPTIONS
.TP 8
.BI \-I " search-path"
Specify the search path to use for meta-config files.
.I search-path
is a comma-separated list of directories to search. Each directory in
the search path is searched for files with a
.I .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.
.TP 8
.B \-D
Enable debugging output.
.TP 8
.B \-V
Print out the version information and exit.
.TP 8
.BI \-X
.BI __xservername__-version
Specify the __xservername__ version in numeric (integer) form.
.TP 8
.BI \-b " subsys-id"
Specify the PCI subsystem ID of the video device.
.TP 8
.BI \-c " class"
Specify the PCI class of the video device.
.TP 8
.BI \-d " device-id"
Specify the PCI devide ID of the video device.
.TP 8
.BI \-r " revision"
Specify the PCI revision of the video device.
.TP 8
.BI \-s " subsysvendor-id"
Specify the PCI subsystem vendor ID of the video device.
.TP 8
.BI \-v " vendor-id"
Specify the PCI vendor ID of the video device.

# Base Xorg getconfig rules file.
#
# The line below is the getconfig rules file signature, and must be the
# first non-blank, non-comment line.
#
Xorg Foundation getconfig rules file. Version: 1.0
#
# Set the weight for the following rules. This should be set, otherwise
# the previously set weight will get used, and you have no idea of knowing
# what that might be.
#
$weight = 1000
#
# Rules. Rules consist of a condition (in perl code) followed by
# a driver name and optionally some additional strings. The start of a
# rule is indicated by a line with no leading white space. subsequent
# lines making up a rule must be indented. Logical lines may be split
# over multiple physical lines by using the usual continuation '\'.
#
# Rules that are not followed by a driver name may be used to do other
# things, like setting the weight as above.
#
#
# Pre-defined variables include:
#
# $vendor PCI vendor ID
# $device PCI device ID
# $revision PCI revision ID
# $subsys PCI subsystem ID
# $subsysVendor PCI subsystem vendor ID
# $class PCI class
# $XorgVersion Xorg version, as a 'v' string.
#
# The Xorg version information is also available as the following:
#
# $XorgVersionNumeric
# $XorgVersionMajor
# $XorgVersionMinor
# $XorgVersionPatch
# $XorgVersionSnap
#
