NAME

       csx_Parse_CISTPL_DEVICEGEO_A - parse the Device Geo A tuple

SYNOPSIS

       #include <sys/pccard.h>

       int32_t csx_Parse_CISTPL_DEVICEGEO_A(client_handle_t ch, tuple_t *tp,
	    cistpl_devicegeo_t *pt);

INTERFACE LEVEL

       Solaris DDI Specific (Solaris DDI)

PARAMETERS

       ch     Client handle returned from csx_RegisterClient(9F).

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

       pt     Pointer to a cistpl_devicegeo_t structure which contains the parsed Device Geo A tuple information upon return from this function.

DESCRIPTION

       This function parses the Device Geo A tuple, CISTPL_DEVICEGEO_A, into a form usable by PC Card drivers.

       The CISTPL_DEVICEGEO_A tuple describes the device geometry of attribute memory partitions.

STRUCTURE MEMBERS

       The structure members of cistpl_devicegeo_t are:

	 uint32_t     info[CISTPL_DEVICEGEO_MAX_PARTITIONS].bus;
	 uint32_t     info[CISTPL_DEVICEGEO_MAX_PARTITIONS].ebs;
	 uint32_t     info[CISTPL_DEVICEGEO_MAX_PARTITIONS].rbs;
	 uint32_t     info[CISTPL_DEVICEGEO_MAX_PARTITIONS].wbs;
	 uint32_t     info[CISTPL_DEVICEGEO_MAX_PARTITIONS].part;
	 uint32_t     info[CISTPL_DEVICEGEO_MAX_PARTITIONS].hwil;

       The fields are defined as follows:

       info[CISTPL_DEVICEGEO_MAX_PARTITIONS].bus

	   This field indicates the card interface width in bytes for the given partition.

       info[CISTPL_DEVICEGEO_MAX_PARTITIONS].ebs

	   This field indicates the minimum erase block size for the given partition.

       info[CISTPL_DEVICEGEO_MAX_PARTITIONS].rbs

	   This field indicates the minimum read block size for the given partition.

       info[CISTPL_DEVICEGEO_MAX_PARTITIONS].wbs

	   This field indicates the minimum write block size for the given partition.

       info[CISTPL_DEVICEGEO_MAX_PARTITIONS].part

	   This field indicates the segment partition subdivisions for the given partition.

       info[CISTPL_DEVICEGEO_MAX_PARTITIONS].hwil

	   This field indicates the hardware interleave for the given partition.

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.
