|
.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
driver implements the PC Card bus.
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
2003-08-20 06:49:57 +00:00
|
|
|
driver supports all PC Card bridges in the system.
|

|
|
|
.Sh TUNABLES
|
|
|
|
|
The driver supports the following tunable parameters, which may be

|
|
|
added to

2005-09-29 16:45:53 +00:00
|
|
|
.Pa /boot/loader.conf
|
|
|
|
|
or set via the
|
|
|
|
|
.Xr sysctl 8
|
|
|
|
|
command:
|
|
|
|
|
.Bl -tag -width ".Cm hw.pccard.cis_debug" -compact
|
|
|
|
|
.It Cm hw.pccard.debug
|
|
|
|
|
Non-zero values cause more verbose information to be printed when a
|
|
|
|
|
16-bit PC Card is inserted or removed.
|
|
|
|
|
.It Cm hw.pccard.cis_debug
|
|
|
|
|
Non-zero value causes the CIS parsing of the 16-bit PC Card to be much
|
|
|
|
|
more verbose and include a complete CIS dump.
|

|
|
|
|
|
This exclusive-use device will report all the CIS chains present in a
|
|
|
|
|
PC Card, if a 16-bit PC Card is inserted in the slot.
|
|
|
|
|
Only one user at a time may access the CIS.
|
|
|
|
|
The CIS is presented as the relevant byte stream from the PC Card.
|
|
|
|
|
For CIS tuples in Attribute Memory (the default), only the even
|
|
|
|
|
locations are presented (the ODD locations are undefined per the
|
|
|
|
|
standard).
|
|
|
|
|
For CIS tuples in Common Memory, every byte is presented to the user.
|
|
|
|
|
Decoding of the CIS tuples is done via a userland program.
|
|
|
|
|
All tuples are presented to the user.
