csx_Parse_CISTPL_CONFIG(9F)				   Kernel Functions for Drivers 			       csx_Parse_CISTPL_CONFIG(9F)

NAME

       csx_Parse_CISTPL_CONFIG - parse Configuration tuple

SYNOPSIS

       #include <sys/pccard.h>

       int32_t csx_Parse_CISTPL_CONFIG(client_handle_t ch, tuple_t *tu, cistpl_config_t *cc);

INTERFACE LEVEL

       Solaris DDI Specific (Solaris DDI)

PARAMETERS

       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.

DESCRIPTION

       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.

STRUCTURE MEMBERS

       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.

RETURN VALUES

       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.

CONTEXT

       This function may be called from user or kernel context.

NOTES

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