CARDMGR(8) CARDMGR(8)
NAME
cardmgr - PCMCIA device manager
SYNOPSIS
cardmgr [-V] [-q] [-d] [-o] [-f] [-v] [-c configpath]
[-m modpath] [-p pidpath] [-s stabfile]
DESCRIPTION
Cardmgr monitors PCMCIA sockets for card insertion and
removal events. When a card is inserted, cardmgr looks up
the card in a database of known cards. If the card can be
identified, appropriate device drivers will be loaded and
bound to the card. When a card is ejected, that card's
drivers will be shut down and unloaded if possible. Based
on the contents of the PCMCIA card configuration database,
cardmgr may also execute arbitrary commands when appropri-
ate cards are either inserted or removed.
All insertion and removal events, device driver loads and
unloads, and startup and shutdown commands are reported in
the system log file. Warnings and errors will also be
logged. Current card and device information for each
socket is recorded in /var/run/stab.
Normally, when a card is identified, cardmgr will send a
beep to the console. A beep is also generated when a card
is successfully configured. A beep of lower pitch is gen-
erated if either of these steps fails. Ejecting a card
produces a single beep.
When cardmgr receives a SIGHUP signal, it will reload its
configuration file. When cardmgr receives a SIGTERM sig-
nal, it will shut down all sockets that are not busy and
then exit, but drivers for busy sockets will stay loaded.
If the PCMCIA_OPTS environment variable is set, its con-
tents will be parsed after the main card configuration
file is read.
OPTIONS
-V Show version information and exit.
-q Quiet mode: don't beep when cards are inserted.
-v Verbose mode: generates more informational messages
during normal operation.
-d Follow module dependencies when loading driver mod-
ules, by defaulting to use modprobe instead of ins-
mod. Normally, cardmgr will try using modprobe
only after an unsuccessful attempt with insmod.
-f Foreground: do not fork and run as a daemon until
after configuring any cards that are already pre-
sent.
-o One pass: configure cards that are present, then
exit. This flag also forces cardmgr to run in the
foreground.
-c configpath
Look for the card configuration database and card
configuration scripts in the specified directory,
instead of /etc/pcmcia.
-m modpath
Look for loadable kernel modules in the specified
directory, instead of /lib/modules/`uname-r`.
-p pidpath
Write the PID of the cardmgr process to the speci-
fied file, instead of /var/run/cardmgr.pid.
-s stabpath
Write current socket information to the specified
file, instead of /var/run/stab.
FILES
/etc/pcmcia/config Card configuration database
/etc/pcmcia/config.opts Local resource settings for PCM-
CIA devices
/var/run/cardmgr.pid PID of active cardmgr process
/var/run/stab Current card and device informa-
tion for each socket.
