- retrieve fields from SCSI sense data

Solaris DDI specific (Solaris DDI).
Pointer to a buffer containing SCSI sense data. The sense data is expected in wire format starting at the response code. It can be in either a fixed or descriptor format.
For scsi_ext_sense_fields(), this is a call-by-reference pointer to uint8_t. A pointer to the INFORMATION field in the sense data may be returned in this parameter.
The scsi_sense_info_uint64() function requires a pointer to uint64_t. The data in the information field is returned as a 64 bit integer. If the sense data information field is 32 bits, fixed format, the most significant 32-bits are 0.
For scsi_ext_sense_fields(), this is a call-by-reference pointer to uint8_t. A pointer to the COMMAND_SPECIFIC INFORMATION field in the sense data can be returned in this parameter.
The scsi_sense_cmdspecific_uint64() function requires a pointer to uint64_t. The data in the command specific information field is returned as a 64 bit integer. If the sense data command specific information field is 32 bits, fixed format, the most significant 32-bits are 0.
Call-by-reference pointer to uint8_t. A pointer to the FIELD REPLACEABLE UNIT CODE field in the sense data can be returned in this parameter.
Call-by-reference pointer to uint8_t. A pointer to the SENSE KEY SPECIFIC field in the sense data can be returned in this parameter.
Call-by-reference pointer to uint8_t. A pointer to the byte containing the ILI, EOM, and FILEMARK flags can be returned in this parameter.
The scsi_ext_sense_fields() function can be used to retrieve any of the extended sense data fields from a sense data buffer, regardless of whether the sense data is in fixed format or in descriptor format.
The information, cmd_spec_info, fru_code, sk_specific, and stream_specific parameters are all call-by-reference output parameters. Each parameter corresponds to one or more of the extended sense data fields. Any of these parameters can be passed as NULL if the caller is not interested in the associated data.
If the requested data is present and valid for each output parameter, the pointer passed in is set to point to the relevant location in the sense buffer. If the data is not present or invalid, the pointer is set to NULL. For example, a caller that requests a pointer to the information field would get NULL when an information descriptor is not present for descriptor format sense data or when the valid bit is not set for fixed format sense data.
The information and command specific information fields can be 4 bytes or 8 bytes in length, depending on whether the sense data is in fixed or descriptor format respectively. Drivers can use scsi_validate_sense(9F) to determine the sense data format and, by extension, the length of the information and command specific information fields.
A driver can determine whether integer data is included in the information or command specific information fields based on the asc and ascq sense keys, such as the LBA of a failed disk request. The scsi_sense_info_uint64() function retrieves the contents of the information field as a 64 bit integer and the scsi_sense_cmdspecific_uint64() retrieves the command specific information field as a 64 bit integer.
Drivers should use scsi_validate_sense(9F) to ensure that the sense buffer contains valid sense data.
The scsi_sense_info_uint64() function returns TRUE if the information field is present and valid. Otherwise it returns FALSE.
The scsi_sense_cmdspecific_uint64() function returns TRUE if the command specific information field is present and valid. Otherwise it returns FALSE.
The scsi_ext_sense_fields(), scsi_sense_info_uint64() and scsi_sense_cmdspecific_uint64()() functions can be called from user or interrupt context.
