PCMCIA_CORE(4)

NAME
pcmcia_core - PCMCIA Card Services core module

SYNOPSIS
insmod pcmcia_core.o [pc_debug=n] [setup_delay=n] [resume_delay=n] [shutdown_delay=n] [vcc_settle=n] [reset_time=n] [unreset_delay=n] [unreset_check=n] [unreset_limit=n] [cis_speed=n] [io_speed=n] [strict_cis=n] [probe_io=n] [probe_mem=n]

DESCRIPTION
Pcmcia_core is the core Card Services module, required for all drivers for specific PCMCIA cards. It is loaded prior to loading any socket device drivers.

In the event that kernel version mismatches prevent this module from being loaded, version information can be extracted from the module itself by doing:

    strings -n 10 pcmcia_core.o | head -3

PARAMETERS

pc_debug=n
    Selects the PCMCIA debugging level. This parameter is only available if the module is compiled with debugging enabled. A non-zero value enables debugging.

setup_delay=n
    Sets the delay between when a card is first detected, and when it will be powered up. In 1/100 second increments, the default is 5.

resume_delay=n
    Sets the delay between when a resume event is processed, and when a suspended card will be powered up. In 1/100 second increments, the default is 20.

shutdown_delay=n
    Sets the delay between when when a card removal event is detected, and when the socket will be disabled. In 1/100 second increments, the default is 5.

vcc_settle=n
    Sets the time to wait after first applying power to a socket before accessing a card. In 1/100 second increments, the default is 30.

reset_time=n
    Sets how long the software reset signal will be asserted, in microseconds. The default is 10.

unreset_delay=n
    Sets the delay between when a card is reset, and when the card will first be checked to see if it is ready. In 1/100 second increments, the default is 10. This delay should be increased for cards that raise the ready signal prematurely.

unreset_check=n
    Sets how often to check to see if a card is ready after it is sent a software reset. In 1/100 second increments, the default is 10.

unreset_limit=n
    Sets the maximum number of checks to make before pronouncing a card to be dead. The default is 30.

cis_speed=n
    Sets the access delay in nanoseconds for CIS memory windows. The default is 300 ns.

io_speed=n
    Sets the access delay in nanoseconds for IO port windows. The default is 0.

strict_cis=n
    A flag (zero is false, non-zero is true) indicating if a card's Card Information Structure should be checked for strict conformance to the PCMCIA spec. The default is false.

probe_io=n
    A flag indicating if Card Services should probe IO port regions for conflicts with other devices unknown to Linux. The default is true.

probe_mem=n
    A flag indicating if Card Services should probe memory windows for conflicts with ROM extensions or memory-mapped devices. The default is true.
