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
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 debug
ging.
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 pro
cessed, 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 dis
abled. 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. This only affects card identification.
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.
cb_mem_base=n
Sets the base address to use for memory mapping
CardBus bridge registers. By default, bridges that
are not already initialized by the PCI BIOS will be
mapped at 0x68000000. If this parameter is set,
then this value will override any existing map
pings.
cb_bus_base=n
Specifies that PCI bus numbers for CardBus busses
should be renumbered starting with this value. By
default, bus values that are uninitialized at boot
time will be numbered starting with bus 0x20.
cb_bus_step=n
Specifies the number of bus slots to reserve for
secondary PCI busses, for each CardBus socket, when
busses are renumbered. The default is 2.
