.Sh NAME
.Nm pccard.conf
.Nd
.Xr pccardd 8
configuration file
.Sh DESCRIPTION
The
.Nm pccard.conf
file is the configuration file for the
.Xr pccardd 8
PC-CARD slot management daemon.
It provides information to allow card
identification, and the matching of drivers (along
with driver resources) to the PC-CARD cards.
.Pp
There are four basic elements within the configuration file;
An optional
.Em "resource pool"
preceding the other sections,
and one or more
.Em "card identifiers" ,
and
.Em "device instances" .
The latter two may appear in any order, and may be
interspersed as desired.
.Pp
Each PC-CARD card contains configuration tuples that provide
the manufacturer and card version; these are used
to identify the card specification in the configuration
file, and from this find a driver that can be used to
interface to the particular card. There is a many-to-one mapping
between cards to drivers i.e a single driver may interface to
multiple types of cards. To aid this, card parameters may be
specified separately from the driver to initialise the card or
extract (in the case of a network card) an Ethernet address.
.Pp
Once a driver is allocated to a card, it stays
allocated to that particular card.
However, multiple instances of the same type of driver can be
configured, so that if two cards are plugged in that map to a
similar type of driver, other driver instances of the same name
can be configured.
.Pp
The
.Em insert
and
.Em remove
commands allow a shell command line to be executed.
The command to be executed is the rest of the line after
the keyword. The line can be continued using a backslash.
A simple
macro substitution allows the current kernel device name
.Em ( $device )
and
network card Ethernet address
.Em ( $ether )
to be inserted into the command line.
.Xr Pcmciad 8
uses the
.Xr system 3
subroutine to execute the command line.
.Pp
Numeric values may be expressed as octal, hex or decimal.
If a decimal number has
.Em k
or
.Em K
appended to it, the value is multiplied by 1024. Names may be
quoted using double quotes if spaces are required.
A hash character comments out the rest of the line.
.Ss "Resource pool"
The (optional) section specifies a pool of system resources
such as ISA bus memory address space, Input/Output ports and
interrupt request numbers. This resource pool is used
to allocate address space and interrupt numbers dynamically
according to the requirements specified in each driver
description.
.Pp
The syntax of the resources is as follows:
.Pp
.Dl io Ar start - end ...
.Dl memory Ar address size ...
.Dl ignmemory Ar address size ...
.Dl irq Ar irq-number ...
.Dl ignirq Ar irq-number ...
.Pp
Each of the statements define I/O, memory or IRQ
blocks that can be used to allocate to drivers when
they are initialised.
.Pp
Multiple lines of any of the above statements may be
present to allow separate blocks of each resource to be
defined.
.Pp
"irq" is deprecated option, and it will only be active
if
.Fl I
is passed to
.Xr pccardd 8 .
Use of this option is DISCOURAGED.
The option allows
.Xr pccardd 8
to use
.Ar irq-number
as irq pool for pccard interface cards.
.Pp
"ignirq" supresses the use of specified
.Ar irq-number .
The functionality is same as
.Fl i Ar IRQ
argument for 
.Xr pccardd 8 .
.Ss "Card Identifiers"
The syntax for card identifiers is:
.Pp
.Dl card Ar manufacturer version class
.Dl config Ar index driver interrupt [ flags ]
.Dl ether Ar offset
.Dl insert Ar command
.Dl remove Ar command
.Pp
The first line is mandatory;
the latter statements are optional and can appear in
any order. There may be multiple
.Em config
lines.
The
.Em card
parameters are the Manufacturer name and card version that
is used to match the values from the card's CIS memory. The
.Em class
identifies the card as one of the device classes listed below.
The
.Em config
parameters select the particular card's configuration index
from the range available in the card's CIS, the driver that
is to be associated with this configuration, and the interrupt
level (if any) to be assigned. An optional set of flags may
be assigned.
.Pp
The optional
.Em ether
keyword is used when network cards have their physical Ethernet address
located within the attribute memory of the card. The parameter of this
statement indicates the offset within the attribute memory of the
Ethernet address. This value can be used within insert/remove
commands using the
.Em $ether
macro.
.Pp
The
.Em insert
and
.Em remove
sections allow shell commands to be specified that are executed
when the card is inserted or removed. Multiple
.Em insert
and
.Em remove
commands are allowed, and they are executed in the order they
are listed.
