— PC Card bus driver
driver implements the PC Card bus. The
driver supports all PC Card bridges in the system.
The driver supports the following tunable parameters, which may be added to
or set via the sysctl(8)
- Non-zero values cause more verbose information to be
printed when a 16-bit PC Card is inserted or removed.
- 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.
