NAME
cardmgr - PCMCIA device manager
SYNOPSIS
cardmgr [-V] [-q] [-o] [-f] [-v] [-c configpath] [-m mod_
path] [-p pidfile] [-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/lib/pcmcia/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.
At startup, cardmgr requires that /tmp reside on a
filesystem that permits special device files (i.e., a real
linux filesystem, that is not mounted "nodev").
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. Configuration scripts are
executed with VERBOSE=y. - -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 pidfile
- Write the PID of the cardmgr process to the speci
fied file, instead of /var/run/cardmgr.pid. - -s stabfile
- Write current socket information to the specified
file, instead of /var/lib/pcmcia/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/lib/pcmcia/stab Current card and device informa - tion for each socket.
