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.
