Synopsis

#include <sys/pccard.h> 

int32_t csx_Parse_CISTPL_DEVICE(client_handle_t ch, tuple_t *tu, 
     cistpl_device_t *cd);

int32_t csx_Parse_CISTPL_DEVICE_A(client_handle_t ch, tuple_t *tu,
     cistpl_device_t *cd);

int32_t csx_Parse_CISTPL_DEVICE_OC(client_handle_t ch, tuple_t *tu,
     cistpl_device_t *cd);

int32_t csx_Parse_CISTPL_DEVICE_OA(client_handle_t ch, tuple_t *tu,
     cistpl_device_t *cd);

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).

cd

Pointer to a cistpl_device_t structure which contains the parsed CISTPL_DEVICE, CISTPL_DEVICE_A, CISTPL_DEVICE_OC, or CISTPL_DEVICE_OA tuple information upon return from these functions, respectively.

Description

csx_Parse_CISTPL_DEVICE() and csx_Parse_CISTPL_DEVICE_A() parse the 5 volt Device Information tuples, CISTPL_DEVICE and CISTPL_DEVICE_A, respectively, into a form usable by PC Card drivers.

csx_Parse_CISTPL_DEVICE_OC() and csx_Parse_CISTPL_DEVICE_OA() parse the Other Condition Device Information tuples, CISTPL_DEVICE_OC and CISTPL_DEVICE_OA, respectively, into a form usable by PC Card drivers.

The CISTPL_DEVICE and CISTPL_DEVICE_A tuples are used to describe the card's device information, such as device speed, device size, device type, and address space layout information for Common Memory or Attribute Memory space, respectively.

The CISTPL_DEVICE_OC and CISTPL_DEVICE_OA tuples are used to describe the information about the card's device under a set of operating conditions for Common Memory or Attribute Memory space, respectively.

Structure Members

The structure members of cistpl_device_t are:

uint32_t               num_devices;    /* number of devices found */
cistpl_device_node_t   devnode[CISTPL_DEVICE_MAX_DEVICES];

The structure members of cistpl_device_node_t are:

uint32_t     flags;             /* flags specific to this device */
uint32_t     speed;             /* device speed in device 
                                /*  speed code format */
uint32_t     nS_speed;          /* device speed in nS */
uint32_t     type;              /* device type */
uint32_t     size;              /* device size */
uint32_t     size_in_bytes;     /* device size in bytes */

The fields are defined as follows:

flags

This field indicates whether or not the device is writable, and describes a Vcc voltage at which the PC Card can be operated.

CISTPL_DEVICE_WPS

Write Protect Switch bit is set

Bits which are applicable only for CISTPL_DEVICE_OC and CISTPL_DEVICE_OA are:

CISTPL_DEVICE_OC_MWAIT

Use MWAIT

CISTPL_DEVICE_OC_Vcc_MASK

Mask for Vcc value

CISTPL_DEVICE_OC_Vcc5

CISTPL_DEVICE_OC_VccYY

Y.Y volt operation

speed

The device speed value described in the device speed code unit. If this field is set to CISTPL_DEVICE_SPEED_SIZE_IGNORE, then the speed information will be ignored.

nS_speed

The device speed value described in nanosecond units.

size

The device size value described in the device size code unit. If this field is set to CISTPL_DEVICE_SPEED_SIZE_IGNORE, then the size information will be ignored.

size_in_bytes

The device size value described in byte units.

type

This is the device type code field which is defined as follows:

CISTPL_DEVICE_DTYPE_NULL

No device

CISTPL_DEVICE_DTYPE_ROM

Masked ROM

CISTPL_DEVICE_DTYPE_OTPROM
