.Sh HISTORY
|

The

|

|
driver appeared in
|
|
.Nx 1.3 .
|
|
.Sh BUGS
|
|
.Ss IO space conflicts
|
|
.Nx
|
|
probes the
|
|
.Tn PCMCIA
|
|
IO bus width and uses that information to decide
|
|
where to map
|
|
.Tn PCMCIA
|
|
IO space. For 10-bit wide cards, 0x300-0x3ff is
|
|
used. For 12-bit wide cards, 0x400-0x4ff is used.
|
|
.Pp
|
|
Neither choice is perfect. In the 12-bit case, 0x400 appears to work
|
|
on substantially more devices than 0x300. In the event that
|
|
.Tn PCMCIA
|
|
devices are mapped in 0x400-0xfff and appear to be nonfunctional,
|
|
remapping to 0x300-0x3ff may be appropriate; consult
|
|
.Cd options PCIC_ISA_ALLOC_IOBASE
|
|
and
|
|
.Cd options PCIC_ISA_ALLOC_IOSIZE
|
|
in
|
|
.Xr options 4 .
|
|
Example:
|
|
.Bd -literal -offset indent
|
|
# Avoid pcmcia bus space conflicts with the default io space
|
|
# allocation on 12-bit wide busses (base 0x400 size 0xfff).
|
|
options PCIC_ISA_ALLOC_IOBASE=0x300
|
|
options PCIC_ISA_ALLOC_IOSIZE=0x0ff
|
|
.Ed
|
|
.Ss Interrupt conflicts
|
|
.Nx
|
|
attempts to probe for available interrupts to assign to
|
|
.Tn PCMCIA
|
|
devices. In some cases, it is not possible to detect
|
|
all interrupts in use; in such cases, use of
|
|
.Cd options PCIC_ISA_INTR_ALLOC_MASK
|
|
may be necessary. See
|
|
.Xr options 4 .
|
|
.Ss Unconfigured devices
|
|
During autoconfiguration, if a message is displayed saying that your card
|
|
is "not configured" it indicates that there isn't support for your card
|
|
compiled into the kernel. To fix this problem, it may simply be a matter
|
|
of adding the manufacturer and product IDs to the
|
|
.Tn PCMCIA
|
|
database or adding a front-end attachment to an existing driver. In
|
|
the latter case, it is normally always necessary to get a dump of the
|
|
CIS table from the card. You can do this by adding
|
|
.Cd options PCMCIACISDEBUG
|
|
and
|
|
.Cd options PCMCIADEBUG
|
|
into your kernel config file. Additionally, you will have to patch the
|
|
kernel to enable run-time debugging. This can be done in the source
|
|
by changing the variables
|
|
.Va pcmcia_debug
|
|
and
|
|
.Va pcmciacis_debug
|
|
to 0xff. Alternatively, you can patch the same variables at run-time
|
|
using
|
|
.Xr ddb 4 .
|
|
For most drivers you should also consider enabling any driver-specific
|
|
debugging options.
