Solaris DDI Specific (Solaris DDI)

ch

Client handle returned from csx_RegisterClient(9F).

tu

Pointer to a tuple_t structure (see tuple(9S)) returned by a call to csx_GetFirstTuple(9F) or csx_GetNextTuple(9F).

cc

Pointer to a cistpl_config_t structure which contains the parsed CISTPL_CONFIG tuple information upon return from this function.

This function parses the Configuration tuple, CISTPL_CONFIG, into a form usable by PC Card drivers. The CISTPL_CONFIG tuple is used to describe the general characteristics of 16-bit PC Cards containing I/O devices or using custom interfaces. It may also describe PC Cards, including Memory Only cards, which exceed nominal power supply specifications, or which need descriptions of their power requirements or other information.

The structure members of cistpl_config_t are:

uint32_t present; /* register present flags */ uint32_t nr; /* number of config registers found */ uint32_t hr; /* highest config register index found */ uint32_t regs[CISTPL_CONFIG_MAX_CONFIG_REGS]; /* reg offsets */ uint32_t base; /* base offset of config registers */ uint32_t last; /* last config index */

The fields are defined as follows:

present

This field indicates which configuration registers are present on the PC Card.

CONFIG_OPTION_REG_PRESENT

Configuration Option Register present

CONFIG_STATUS_REG_PRESENT

Configuration Status Register present

CONFIG_PINREPL_REG_PRESENT

Pin Replacement Register present

CONFIG_COPY_REG_PRESENT

Copy Register present

CONFIG_EXSTAT_REG_PRESENT

Extended Status Register present

CONFIG_IOBASE0_REG_PRESENT

IO Base 0 Register present

CONFIG_IOBASE1_REG_PRESENT

IO Base 1 Register present

CONFIG_IOBASE2_REG_PRESENT

IO Base2 Register present

CONFIG_IOBASE3_REG_PRESENT

IO Base3 Register present

CONFIG_IOLIMIT_REG_PRESENT

IO Limit Register present

nr

This field specifies the number of configuration registers that are present on the PC Card.

hr

This field specifies the highest configuration register number that is present on the PC Card.

regs

This array contains the offset from the start of Attribute Memory space for each configuration register that is present on the PC Card. If a configuration register is not present on the PC Card, the value in the corresponding entry in the regs array is undefined.

base

This field contains the offset from the start of Attribute Memory space to the base of the PC Card configuration register space.

last

This field contains the value of the last valid configuration index for this PC Card.

CS_SUCCESS

Successful operation.

CS_BAD_HANDLE

Client handle is invalid.

CS_UNKNOWN_TUPLE

Parser does not know how to parse tuple.

CS_NO_CARD

No PC Card in socket.

CS_NO_CIS

No Card Information Structure (CIS) on PC Card.

CS_UNSUPPORTED_FUNCTION

No PCMCIA hardware installed.

This function may be called from user or kernel context.

csx_GetFirstTuple(9F), csx_GetTupleData(9F), csx_Parse_CISTPL_CFTABLE_ENTRY(9F), csx_RegisterClient(9F), csx_ValidateCIS(9F), tuple(9S)

PC Card 95 Standard, PCMCIA/JEIDA

PC Card drivers should not attempt to use configurations beyond the "last" member in the cistpl_config_t structure.
