csx_Parse_CISTPL_CONFIG(9Kernel Functions for Drivecsx_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 specifi‐
       cations, 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 regis‐
		       ters 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 reg‐
		       ister  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 con‐
		       figuration register space.

       last	       This field contains the value of the last valid config‐
		       uration 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.

       csx_Parse_CISTPL_CFTABLE_ENTRY(9F),  csx_RegisterClient(9F),  csx_Vali‐
       dateCIS(9F), tuple(9S)

       PC Card 95 Standard, PCMCIA/JEIDA

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