csx_Parse_CISTPL_DEVICEGEO_A - man pages section 9: DDI and DKI Kernel Functions

Language:

csx_Parse_CISTPL_DEVICEGEO_A(9F)

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.
