.Sh DESCRIPTION
|
|
.Nx
|
|
provides machine-independent bus support and
|
|
drivers for CardBus devices.
|
|
.Pp
|
|
The
|
|
.Cm cbb
|
|
device represents the CardBus controller.
|
|
Each controller has a number
|
|
of slots, represented by the
|
|
.Cm cardslot
|
|
devices. A slot can have either a CardBus card or a
|
|
.Tn PCMCIA
|
|
card, which are attached with the
|
|
.Cm cardbus
|
|
or
|
|
.Cm pcmcia
|
|
devices, respectively.
|

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver appeared in

.Ss Memory space conflicts
|
|
.Nx
|
|
maps memory on Cardbus and PCMCIA cards in order to access the cards
|
|
(including reading CIS tuples on PCMCIA cards)
|
|
and access the devices using the
|
|
.Tn RBUS
|
|
abstraction.
|
|
When the mapping does not work, PCMCIA cards are typically ignored on
|
|
insert, and Cardbus cards are recognized but nonfunctional.
|
|
On i386, the kernel has a heuristic to choose a memory address for
|
|
mapping, defaulting to 1 GB, but choosing 0.5 GB on machines with less
|
|
than 192 MB RAM and 2 GB on machines with more than 1 GB of RAM.
|
|
The intent is to use an address that is larger than available RAM, but
|
|
low enough to work; some systems seem to have trouble with
|
|
addresses requiring more than 20 address lines.
|
|
On i386, the following kernel configuration line disables the
|
|
heuristics and forces Cardbus
|
|
memory space to be mapped at 512M; this value makes Cardbus support
|
|
(including PCMCIA attachment under a cbb) work on some notebook
|
|
models, including the IBM Thinkpad 600E (2645-4AU) and the Compaq
|
|
ARMADA M700:
