# Udev rules for Archlinux by Tobias Powalowski <tpowa@archlinux.org> # # This ruleset should provide a DevFS-compatible device tree. # # There are a number of modifiers that are allowed to be used in some # of the different fields. They provide the following subsitutions: # # %n the "kernel number" of the device. # For example, 'sda3' has a "kernel number" of '3' # %k the kernel name for the device. # %M the kernel major number for the device # %m the kernel minor number for the device # %b the bus id for the device # %c the string returned by the PROGRAM # %s{filename} the content of a sysfs attribute. # %% the '%' char itself. # # There are a number of modifiers that are allowed to be used in some of the # fields. See the udev man page for a full description of them. # global stuff # ##################################### # Early rules - begin ##################################### # wait for sysfs ACTION=="add", KERNEL=="[0-9]*:[0-9]*", SUBSYSTEM=="scsi", WAIT_FOR_SYSFS="ioerr_cnt" # Setting timeout for tape-devices (type 1) to 900 seconds # and 60 seconds for device types 0, 7 and 14 SUBSYSTEM=="scsi", KERNEL=="[0-9]*:[0-9]*", ACTION=="add", ATTR{type}=="0|7|14", ATTR{timeout}="60" SUBSYSTEM=="scsi", KERNEL=="[0-9]*:[0-9]*", ACTION=="add", ATTR{type}=="1", ATTR{timeout}="900" ##################################### # Early rules -end ##################################### ##################################### ###### Hotplug rules - begin ##################################### # Modaliases to load ACTION=="add", ENV{MODALIAS}=="?*", RUN{ignore_error}+="/lib/udev/load-modules.sh $env{MODALIAS}" # SCSI addon modules ACTION=="add", SUBSYSTEM=="scsi", ATTRS{type}=="[07]", RUN+="/lib/udev/load-modules.sh sd_mod" ACTION=="add", SUBSYSTEM=="scsi", ATTRS{type}=="14", RUN+="/lib/udev/load-modules.sh sd_mod" ACTION=="add", SUBSYSTEM=="scsi", ATTRS{type}=="[45]", RUN+="/lib/udev/load-modules.sh sr_mod" ACTION=="add", SUBSYSTEM=="scsi", ATTRS{type}=="1", ATTRS{vendor}=="Onstream", ATTRS{model}!="ADR*", RUN+="/lib/udev/load-modules.sh osst" ACTION=="add", SUBSYSTEM=="scsi", ATTRS{type}=="1", ATTRS{vendor}=="Onstream", ATTRS{model}=="ADR*", RUN+="/lib/udev/load-modules.sh st" ACTION=="add", SUBSYSTEM=="scsi", ATTRS{type}=="1", ATTRS{vendor}!="Onstream", RUN+="/lib/udev/load-modules.sh st" ACTION=="add", SUBSYSTEM=="scsi", ATTRS{type}=="[23689]", TEST!="[module/sg]", RUN+="/lib/udev/load-modules.sh sg" ACTION=="add", SUBSYSTEM=="mmc", RUN+="/lib/udev/load-modules.sh mmc_block" LABEL="hotplug_driver_loaded" # FIRMWARE ACTION=="add", SUBSYSTEM=="firmware", ENV{FIRMWARE}=="?*", RUN+="/lib/udev/firmware.sh" ##################################### ##### Hotplug rules - end ##################################### ##################################### ###### CD/DVD symlinks - begin ##################################### ACTION=="add", SUBSYSTEMS=="ide", KERNEL=="hd[a-z]", IMPORT="/lib/udev/cdrom_id --export $tempnode" ACTION=="add", SUBSYSTEMS=="scsi", KERNEL=="sr[0-9]*", IMPORT="/lib/udev/cdrom_id --export $tempnode" ACTION=="add", SUBSYSTEMS=="scsi", KERNEL=="scd[a-z]", IMPORT="/lib/udev/cdrom_id --export $tempnode" ENV{ID_CDROM}=="?*", SYMLINK+="cd/cdrom-%b" ENV{ID_CDROM_CD_RW}=="?*", SYMLINK+="cd/cdrw-%b" ENV{ID_CDROM_DVD}=="?*", SYMLINK+="cd/dvd-%b" ENV{ID_CDROM_DVD_R}=="?*", SYMLINK+="cd/dvd-%b" ##################################### ###### CD/DVD symlinks - end ##################################### ##################################### ##### PCMCIA rules - begin ##################################### # PCMCIA devices: # # Very few CIS firmware entries (which we use for matching) # are so broken that we need to read out random bytes of it # instead of the manufactor, card or product ID.
