45.Dt DEVD.CONF 5 46.Os 47.Sh NAME 48.Nm devd.conf 49.Nd configuration file for 50.Xr devd 8 51.Sh DESCRIPTION 52.Ss General Syntax 53A 54.Xr devd 8 55configuration consists of two general features, statements 56and comments. 57All statements end with a semicolon. 58Many statements can contain substatements, which are also 59terminated with a semicolon. 60.Pp 61The following statements are supported: 62.Bl -tag -width ".Ic options" 63.It Ic attach 64Specifies various matching criteria and actions to perform when 65a newly attached device matches said criteria. 66.It Ic detach 67Specifies various matching criteria and actions to perform when 68a newly detached device matches said criteria. 69.It Ic nomatch 70Specifies various matching criteria and actions to perform when 71no device driver currently loaded in the kernel claims a (new) 72device. 73.It Ic notify 74Specifies various matching criteria and actions to perform when the kernel 75sends an event notification to userland. 76.It Ic options 77Specifies various options and parameters for the operation of 78.Xr devd 8 . 79.El 80.Pp 81Statements may occur in any order in the configuration file, and may be 82repeated as often as required. 83Further details on the syntax and meaning of each statement and their 84substatements are explained below. 85.Pp 86Each statement, except 87.Ic options 88has a priority (an arbitrary number) associated with it, where 89.Ql 0 90is defined as the lowest priority. 91If two statements match the same event, only the action of the statement with 92highest priority will be executed. 93In this way generic statements can be overridden for devices or 94notifications that require special attention. 95.Pp 96The general syntax of a statement is: 97.Bd -literal -offset indent 98statement priority { 99 substatement "value"; 100 ... 101 substatement "value"; 102}; 103.Ed 104.Ss Sub-statements 105The following sub-statements are supported within the 106.Ic options 107statement. 108.Bl -tag -width ".Ic directory" 109.It Ic directory Qq Ar /some/path ; 110Adds the given directory to the list of directories from which 111.Xr devd 8 112will read all files named "*.conf" as further 113configuration files. 114Any number of 115.Ic directory 116statements can be used. 117.It Ic pid-file Qq Pa /var/run/devd.pid ; 118Specifies PID file. 119.It Ic set Ar regexp-name Qq Ar (some|regexp) ; 120Creates a regular expression and assigns it to the variable 121.Ar regexp-name . 122The variable is available throughout the rest of 123the configuration file. 124If the string begins with 125.Ql \&! , 126it matches if the regular expression formed by the rest of the string 127does not match. 128All regular expressions have an implicit 129.Ql ^$ 130around them. 131.El 132.Pp 133The following sub-statements are supported within the 134.Ic attach 135and 136.Ic detach 137statements. 138.Bl -tag -width ".Ic directory" 139.It Ic action Qq Ar command ; 140Command to execute upon a successful match. 141Example 142.Dq Li "/etc/pccard_ether $device-name start" . 143.It Ic class Qq Ar string ; 144This is shorthand for 145.Dq Ic match Qo Li class Qc Qq Ar string . 146.It Ic device-name Qq string ; 147This is shorthand for 148.Dq Ic match Qo Li device-name Qc Qq Ar string . 149This matches a device named 150.Ar string , 151which is allowed to be a regular expression or a variable previously created 152containing a regular expression. 153The 154.Dq Li device-name 155variable 156is available for later use with the 157.Ic action 158statement. 159.It Ic match Qo Ar variable Qc Qq Ar value ; 160Matches the content of 161.Ar value 162against 163.Ar variable ; 164the content of 165.Ar value 166may be a regular expression. 167Not required during 168.Ic attach 169nor 170.Ic detach 171events since the 172.Ic device-name 173statement takes care of all device matching. 174For a partial list of variables, see below. 175.It Ic media-type Qq Ar string ; 176For network devices, 177.Ic media-type 178will match devices that have the given media type. 179Valid media types are: 180.Dq Li Ethernet , 181.Dq Li Tokenring , 182.Dq Li FDDI , 183.Dq Li 802.11 , 184and 185.Dq Li ATM . 186.It Ic subdevice Qq Ar string ; 187This is shorthand for 188.Dq Ic match Qo Li subdevice Qc Qq Ar string . 189.El 190.Pp 191The following sub-statements are supported within the 192.Ic nomatch 193statement. 194.Bl -tag -width ".Ic directory" 195.It Ic action Qq Ar command ; 196Same as above. 197.It Ic match Qo Ar variable Qc Qq Ar value ; 198Matches the content of 199.Ar value 200against 201.Ar variable ; 202the content of 203.Ar value 204may be a regular expression. 205For a partial list of variables, see below. 206.El 207.Pp 208The following sub-statements are supported within the 209.Ic notify 210statement. 211The 212.Dq Li notify 213variable is available inside this statement and contains, a value, depending 214on which system and subsystem that delivered the event. 215.Bl -tag -width ".Ic directory" 216.It Ic action Qq Ar command ; 217Command to execute upon a successful match. 218Example 219.Dq Li "/etc/rc.d/power_profile $notify" . 220.It Ic match Qo Ar system | subsystem | type | notify Qc Qq Ar value ; 221Any number of 222.Ic match 223statements can exist within a 224.Ic notify 225statement; 226.Ar value 227can be either a fixed string or a regular expression. 228Below is a list of available systems, subsystems, and types. 229.It Ic media-type Qq Ar string ; 230See above. 231.El 232.Ss Variables that can be used with the match statement 233A partial list of variables and their possible values that can be used together 234with the 235.Ic match 236statement. 237.Pp 238.Bl -tag -width ".Li manufacturer"

459configuration file. 460To appeal to programmers of all kinds, they can 461be written in C, C++, or shell/Perl constructs. 462.Pp 463C-style comments start with the two characters 464.Ql /* 465(slash, star) and end with 466.Ql */ 467(star, slash). 468Because they are completely delimited with these characters, 469they can be used to comment only a portion of a line or to span 470multiple lines. 471.Pp 472C-style comments cannot be nested. 473For example, the following is 474not valid because the entire comment ends with the first 475.Ql */ : 476.Bd -literal -offset indent 477/* This is the start of a comment. 478 This is still part of the comment. 479/* This is an incorrect attempt at nesting a comment. */ 480 This is no longer in any comment. */ 481.Ed 482.Pp 483C++-style comments start with the two characters 484.Ql // 485(slash, slash) and continue to the end of the physical line. 486They cannot be continued across multiple physical lines; to have 487one logical comment span multiple lines, each line must use the 488.Ql // 489pair. 490For example: 491.Bd -literal -offset indent 492// This is the start of a comment. The next line 493// is a new comment, even though it is logically 494// part of the previous comment. 495.Ed 496.Sh FILES 497.Bl -tag -width ".Pa /etc/devd.conf" -compact 498.It Pa /etc/devd.conf 499The 500.Xr devd 8 501configuration file. 502.El 503.Sh EXAMPLES 504.Bd -literal 505# 506# This will catch link down events on the interfaces fxp0 and ath0 507# 508notify 0 { 509 match "system" "IFNET"; 510 match "subsystem" "(fxp0|ath0)"; 511 match "type" "LINK_DOWN"; 512 action "logger $subsystem is DOWN"; 513}; 514 515# 516# Match lid open/close events 517# These can be combined to a single event, by passing the 518# value of $notify to the external script. 519# 520notify 0 { 521 match "system" "ACPI"; 522 match "subsystem" "Lid"; 523 match "notify" "0x00"; 524 action "logger Lid closed, we can sleep now!"; 525}; 526 527notify 0 { 528 match "system" "ACPI"; 529 match "subsystem" "Lid"; 530 match "notify" "0x01"; 531 action "logger Lid opened, the sleeper must awaken!"; 532}; 533 534# 535# Match a USB device type 536# 537notify 0 { 538 match "system" "USB"; 539 match "subsystem" "INTERFACE"; 540 match "type" "ATTACH"; 541 match "intclass" "0x0e"; 542 action "logger USB video device attached"; 543}; 544 545# 546# Try to configure ath and wi devices with pccard_ether 547# as they are attached. 548# 549attach 0 { 550 device-name "(ath|wi)[0-9]+"; 551 action "/etc/pccard_ether $device-name start"; 552}; 553 554# 555# Stop ath and wi devices as they are detached from 556# the system. 557# 558detach 0 { 559 device-name "(ath|wi)[0-9]+"; 560 action "/etc/pccard_ether $device-name stop"; 561}; 562.Ed 563.Pp 564The installed 565.Pa /etc/devd.conf 566has many additional examples. 567.Sh SEE ALSO 568.Xr coretemp 4 , 569.Xr memtemp 4 , 570.Xr devfs 5 , 571.Xr re_format 7 , 572.Xr devd 8 573
