Kernel Functions for Driverscsx_Parse_CISTPL_DEVICEGEO(9F)


NAME

 csx_Parse_CISTPL_DEVICEGEO - parse the Device Geo tuple

SYNOPSIS

 
#include <sys/pccard.h> 
int32_t csx_Parse_CISTPL_DEVICEGEO(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 tuple information upon return from this function.

DESCRIPTION

 

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

The CISTPL_DEVICEGEO tuple describes the device geometry of common 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

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.
