 .Sh NAME
 .Nm devd.conf
 .Nd configuration file for
 .Xr devd 8
 .Sh DESCRIPTION
 .Ss General Syntax
 A
 .Xr devd 8
 configuration consists of two general features, statements
 and comments.
 All statements end with a semicolon.
 Many statements can contain substatements, which are also
 terminated with a semicolon.
 .Pp
 The following statements are supported:
 .Bl -tag -width ".Ic options"
 .It Ic attach
 Specifies various matching criteria and actions to perform when
 a newly attached device matches said criteria.
 .It Ic detach
 Specifies various matching criteria and actions to perform when
 a newly detached device matches said criteria.
 .It Ic nomatch
 Specifies various matching criteria and actions to perform when
 no device driver currently loaded in the kernel claims a (new)
 device.
 .It Ic notify
 Specifies various matching criteria and actions to perform when the kernel
 sends an event notification to userland.
 .It Ic options
 Specifies various options and parameters for the operation of
 .Xr devd 8 .
 .El
 .Pp
 Statements may occur in any order in the configuration file, and may be
 repeated as often as required.
 Further details on the syntax and meaning of each statement and their
 substatements are explained below.
 .Pp
 Each statement, except
 .Ic options
 has a priority (an arbitrary number) associated with it, where
 .Ql 0
 is defined as the lowest priority.
 If two statements match the same event, only the action of the statement with
 highest priority will be executed.
 In this way generic statements can be overridden for devices or
 notifications that require special attention.
 .Pp
 The general syntax of a statement is:
 .Bd -literal -offset indent
 statement priority {
 	substatement "value";
 	...
 	substatement "value";
 };
 .Ed
 .Ss Sub-statements
 The following sub-statements are supported within the
 .Ic options
 statement.
 .Bl -tag -width ".Ic directory"
 .It Ic directory Qq Ar /some/path ;
 Adds the given directory to the list of directories from which
 .Xr devd 8
 will read all files named "*.conf" as further
 configuration files.
 Any number of
 .Ic directory
 statements can be used.
 .It Ic pid-file Qq Pa /var/run/devd.pid ;
 Specifies PID file.
 .It Ic set Ar regexp-name Qq Ar (some|regexp) ;
 Creates a regular expression and assigns it to the variable
 .Ar regexp-name .
 The variable is available throughout the rest of
 the configuration file.
 If the string begins with
 .Ql \&! ,
 it matches if the regular expression formed by the rest of the string
 does not match.
 All regular expressions have an implicit
 .Ql ^$
 around them.
 .El
 .Pp
 The following sub-statements are supported within the
 .Ic attach
 and
 .Ic detach
 statements.
 .Bl -tag -width ".Ic directory"
 .It Ic action Qq Ar command ;
 Command to execute upon a successful match.
 Example
 .Dq Li "/etc/pccard_ether $device-name start" .
 .It Ic class Qq Ar string ;
 This is shorthand for
 .Dq Ic match Qo Li class Qc Qq Ar string .
 .It Ic device-name Qq string ;
 This is shorthand for
 .Dq Ic match Qo Li device-name Qc Qq Ar string .
 This matches a device named
 .Ar string ,
 which is allowed to be a regular expression or a variable previously created
 containing a regular expression.
 The
 .Dq Li device-name
 variable
 is available for later use with the
 .Ic action
 statement.
 .It Ic match Qo Ar variable Qc Qq Ar value ;
 Matches the content of
 .Ar value
 against
 .Ar variable ;
 the content of
 .Ar value
 may be a regular expression.
 Not required during
 .Ic attach
 nor
 .Ic detach
 events since the
 .Ic device-name
 statement takes care of all device matching.
 For a partial list of variables, see below.
 .It Ic media-type Qq Ar string ;
 For network devices,
 .Ic media-type
 will match devices that have the given media type.
 Valid media types are:
 .Dq Li Ethernet ,
 .Dq Li Tokenring ,
 .Dq Li FDDI ,
 .Dq Li 802.11 ,
 and
 .Dq Li ATM .
 .It Ic subdevice Qq Ar string ;
 This is shorthand for
 .Dq Ic match Qo Li subdevice Qc Qq Ar string .
 .El
 .Pp
 The following sub-statements are supported within the
 .Ic nomatch
 statement.
 .Bl -tag -width ".Ic directory"
 .It Ic action Qq Ar command ;
 Same as above.
 .It Ic match Qo Ar variable Qc Qq Ar value ;
 Matches the content of
 .Ar value
 against
 .Ar variable ;
 the content of
 .Ar value
 may be a regular expression.
 For a partial list of variables, see below.
 .El
 .Pp
 The following sub-statements are supported within the
 .Ic notify
 statement.
 The
 .Dq Li notify
 variable is available inside this statement and contains, a value, depending
 on which system and subsystem that delivered the event.
 .Bl -tag -width ".Ic directory"
 .It Ic action Qq Ar command ;
 Command to execute upon a successful match.
 Example
 .Dq Li "/etc/rc.d/power_profile $notify" .
 .It Ic match Qo Ar system | subsystem | type | notify Qc Qq Ar value ;
 Any number of
 .Ic match
 statements can exist within a
 .Ic notify
 statement;
 .Ar value
 can be either a fixed string or a regular expression.
 Below is a list of available systems, subsystems, and types.
 .It Ic media-type Qq Ar string ;
 See above.
 .El
 .Ss Variables that can be used with the match statement
 A partial list of variables and their possible values that can be used together
 with the
 .Ic match
 statement.
 The variables are published by the bus based on characteristics of the device
 that generated the event (for device events).
 Variables for other classes of events are dependent on those events.

 A link state change to UP on the interface
 .Dq Li fxp0
 would result in the following notify event:
 .Bd -literal -offset indent
 system=IFNET subsystem=fxp0 type=LINK_UP

 An AC line state change to

 .Ed
 .Ss Comments
 Comments may appear anywhere that whitespace may appear in a
 configuration file.
 To appeal to programmers of all kinds, they can
 be written in C, C++, or shell/Perl constructs.
 .Pp
 C-style comments start with the two characters
 .Ql /*
 (slash, star) and end with
 .Ql */
 (star, slash).
 Because they are completely delimited with these characters,
 they can be used to comment only a portion of a line or to span
 multiple lines.
 .Pp
 C-style comments cannot be nested.
 For example, the following is
 not valid because the entire comment ends with the first
 .Ql */ :
 .Bd -literal -offset indent
 /* This is the start of a comment.
    This is still part of the comment.
 /* This is an incorrect attempt at nesting a comment. */
    This is no longer in any comment. */
 .Ed
 .Pp
 C++-style comments start with the two characters
 .Ql //
 (slash, slash) and continue to the end of the physical line.
 They cannot be continued across multiple physical lines; to have
 one logical comment span multiple lines, each line must use the
 .Ql //
 pair.
 For example:
 .Bd -literal -offset indent
 // This is the start of a comment.  The next line
 // is a new comment, even though it is logically
 // part of the previous comment.
 .Ed
 .Ss Notes on Variable Expansion
 To prevent issues with special shell characters, the following happens for each
 variable
 .Ic $foo .
 .Bl -enum
 .It
 The characters
 .Dq $'
 are inserted.
 .It
 The string
 .Dq $foo
 is removed.
 .It
 The value of the
 .Ic foo
 variable is inserted into the buffer with all single quote characters
 prefixed by a backslash.
 .El
 .Pp
 See
 .Xr sh 1
 for what this construct means.
 It is safe in all context, except one: inside single quotes.
 If foo=meta and bar=var, then a rule like the following:
 .Bd -literal -offset indent -compact
 action "echo '$foo $bar'";
 .Ed
 will be presented to the shell via
 .Xr system 3
 as
 .Bd -literal -offset indent -compact
 echo '$'meta' $'var''
 .Ed
 which produces the following output:
 .Bd -literal -offset indent -compact
 $meta $var
 .Ed
 as its output.
 This is an unanticipated result.
 A future version of this software will change this behavior.
 Users are discouraged from using single quotes inside
 .Ic action
 value without due care.
 .Pp
 The above should be written as
 .Bd -literal -offset indent -compact
 action "echo $foo' '$bar"
 .Ed
 to produce a single argument to echo.
 Given the above expansion, juxtaposing bare variables with
 single quote expressions will produce the right output,
 regardless of the value of the variable.

 .Sh DESCRIPTION
 The
 .Nm
 device provides multiple virtual terminals with an extensive feature
 set:
 .Bl -item -offset indent
 .It
 Unicode UTF-8 text with double-width characters.
 .It
 Large font maps in graphics mode, including support for Asian
 character sets.
 .It
 Graphics-mode consoles.
 .It
 Integration with
 KMS
 .Pq Kernel Mode Setting
 video drivers for switching between the
 .Em X Window System
 and virtual terminals.
 .El
 .Ss Virtual Terminals
 Multiple virtual terminals are provided on a single computer.
 Up to sixteen virtual terminals can be defined.
 A single virtual terminal is connected to the screen and keyboard
 at a time.
 Key combinations are used to select a virtual terminal.
 Alt-F1 through Alt-F12 correspond to the first twelve virtual terminals.
 If more than twelve virtual terminals are created, Shift-Alt-F1 through
 Shift-Alt-F4 are used to switch to the additional terminals.
 .Ss Copying and Pasting Text with a Mouse
 Copying and pasting text from the screen with a mouse is supported.
 Press and hold down mouse button 1, usually the left button, while
 moving the mouse to select text.
 Selected text is highlighted with reversed foreground and background
 colors.
 To select more text after releasing mouse button 1, press mouse button
 3, usually the right button.
 To paste text that has been selected, press mouse button 2, usually the
 middle button.
 The text is entered as if it were typed at the keyboard.
 The
 .Dv VT_TWOBUTTON_MOUSE
 kernel option can be used with mice that only have two buttons.
 Setting this option makes the second mouse button into the
 paste button.
 See
 .Xr moused 8
 for more information.
 .Ss Scrolling Back
 Output that has scrolled off the screen can be reviewed by pressing the
 Scroll Lock key, then scrolling up and down with the arrow keys.
 The Page Up and Page Down keys scroll up or down a full screen at a
 time.
 The Home and End keys jump to the beginning or end of the scrollback
 buffer.
 When finished reviewing, press the Scroll Lock key again to return to
 normal use.
 .Sh DRIVER CONFIGURATION
 .Ss Kernel Configuration Options
 These kernel options control the
 .Nm
 driver.
 .Bl -tag -width MAXCONS
 .It Dv TERMINAL_NORM_ATTR= Ns Pa attribute
 .It Dv TERMINAL_KERN_ATTR= Ns Pa attribute
 These options change the default colors used for normal and kernel
 text.
 Available colors are defined in
 .In sys/terminal.h .
 See
 .Sx EXAMPLES
 below.
 .It Dv VT_MAXWINDOWS=N
 Set the number of virtual terminals to be created to
 .Fa N .
 The value defaults to 12.
 .It Dv VT_ALT_TO_ESC_HACK=1
 When the Alt key is held down while pressing another key, send an ESC
 sequence instead of the Alt key.
 .It Dv VT_TWOBUTTON_MOUSE
 If defined, swap the functions of mouse buttons 2 and 3.
 In effect, this makes the right-hand mouse button perform a paste.
 These options are checked in the order shown.
 .It Dv SC_NO_CUTPASTE
 Disable mouse support.
 .It VT_FB_MAX_WIDTH=X
 Set the maximum width to
 .Fa X .
 .It VT_FB_MAX_HEIGHT=Y
 Set the maximum height to
 .Fa Y .
 .El
 .Sh BACKWARDS COMPATIBILITY
 Several options are provided for compatibility with the previous
 console device,
 .Xr sc 4 .
 These options will be removed in a future
 .Fx
 version.

 .El
 .Sh START-UP OPERATION WITH X86 BIOS SYSTEMS
 The computer BIOS starts in text mode, and
 the
 .Fx
 .Xr loader 8
 runs, loading the kernel.
 If
 .Va hw.vga.textmode
 is set, the system remains in text mode.
 Otherwise,
 .Nm
 switches to 640x480x16 VGA mode using
 .Cm vt_vga .
 If a KMS
 .Pq Kernel Mode Setting
 video driver is available, the display is switched to high resolution
 and the KMS driver takes over.
 When a KMS driver is not available,
 .Cm vt_vga
 remains active.
 .Sh LOADER TUNABLES
 These settings can be entered at the
 .Xr loader 8
 prompt or in
 .Xr loader.conf 5 .
 .Bl -tag -width indent
 .It Va hw.vga.textmode
 Set to 1 to use virtual terminals in text mode instead of graphics mode.
 Features that require graphics mode, like loadable fonts, will be
 disabled.
 .It Va hw.vga.acpi_ignore_no_vga
 Set to 1 to force the usage of the VGA driver regardless of whether
 ACPI IAPC_BOOT_ARCH signals no VGA support.
 Can be used to workaround firmware bugs in the ACPI tables.
 .It Va kern.vty
 Set this value to
 .Ql vt
 or
 .Ql sc
 to choose a specific system console, overriding the default.
 The
 .Pa GENERIC
 kernel uses
 .Nm
 when this value is not set.
 .It Va kern.vt.color. Ns Ar colornum Ns Va .rgb
 Set this value to override default palette entry for color
 .Pa colornum
 which should be in a range from 0 to 15 inclusive.
 The value should be either a comma-separated triplet of
 red, green, and blue values in a range from 0 to 255 or
 HTML-like hex triplet.
 See
 .Sx EXAMPLES
 below.
 .It Va kern.vt.fb.default_mode
 Set this value to a graphic mode to override the default mode picked by the
 .Nm
 backend.
 The mode is applied to all output connectors.
 This is currently only supported by the
 .Cm vt_fb
 backend when it is paired with a KMS video driver.
 .It Va kern.vt.fb.modes. Ns Pa connector_name
 Set this value to a graphic mode to override the default mode picked by the
 .Nm
 backend.
 This mode is applied to the output connector
 .Pa connector_name
 only.
 It has precedence over
 .Va kern.vt.fb.default_mode .
 The names of available connector names can be found in
 .Xr dmesg 8
 after loading the KMS driver.
 It will contain a list of connectors and their associated tunables.
 This is currently only supported by the
 .Cm vt_fb
 backend when it is paired with a KMS video driver.
 .El
 .Sh KEYBOARD SYSCTL TUNABLES
 These settings control whether certain special key combinations are enabled or
 ignored.
 The specific key combinations can be configured by using a
 .Xr keymap 5
 file.
 .Pp
 These settings can be entered at the
 .Xr loader 8
 prompt or in
 .Xr loader.conf 5
 and can also be changed at runtime with the
 .Xr sysctl 8
 command.
 .Bl -tag -width indent
 .It Va kern.vt.kbd_halt
 Enable halt keyboard combination.
 .It Va kern.vt.kbd_poweroff
 Enable power off key combination.
 .It Va kern.vt.kbd_reboot
 Enable reboot key combination, usually Ctrl+Alt+Del.
 .It Va kern.vt.kbd_debug
 Enable debug request key combination, usually Ctrl+Alt+Esc.
 .It Va kern.vt.kbd_panic
 Enable panic key combination.
 .El
 .Sh OTHER SYSCTL TUNABLES
 These settings can be entered at the
 .Xr loader 8
 prompt, set in
 .Xr loader.conf 5 ,
 or changed at runtime with
 .Xr sysctl 8 .
 .Bl -tag -width indent
 .It Va kern.vt.enable_bell
 Enable the terminal bell.

 .Sh EXAMPLES
 This example changes the default color of normal text to green on a
 black background, or black on a green background when reversed.
 Note that white space cannot be used inside the attribute string
 because of the current implementation of
 .Xr config 8 .
 .Pp
 .Dl "options TERMINAL_NORM_ATTR=(FG_GREEN|BG_BLACK)"
 .Pp
 This line changes the default color of kernel messages to be bright red
 on a black background, or black on a bright red background when reversed.
 .Pp
 .Dl "options TERMINAL_KERN_ATTR=(FG_LIGHTRED|BG_BLACK)"
 .Pp
 To set a 1024x768 mode on all output connectors, put the following line in
 .Pa /boot/loader.conf :
 .Pp
 .Dl kern.vt.fb.default_mode="1024x768"
 .Pp
 To set a 800x600 only on a laptop builtin screen, use the following line instead:
 .Pp
 .Dl kern.vt.fb.modes.LVDS-1="800x600"
 .Pp
 The connector name was found in
 .Xr dmesg 8 :
 .Pp
 .Dl info: [drm] Connector LVDS-1: get mode from tunables:
 .Dl info: [drm]   - kern.vt.fb.modes.LVDS-1
 .Dl info: [drm]   - kern.vt.fb.default_mode
 .Pp
 To set black and white colors of console palette
 .Pp
 .Dl kern.vt.color.0.rgb="10,10,10"
 .Dl kern.vt.color.15.rgb="#f0f0f0"
