NAME

       ata_to_sense_error - convert ATA error to SCSI error

SYNOPSIS

       void ata_to_sense_error(unsigned id, u8 drv_stat, u8 drv_err, u8 * sk, u8 * asc, u8 * ascq, int verbose);

ARGUMENTS

       id
	   ATA device number

       drv_stat
	   value contained in ATA status register

       drv_err
	   value contained in ATA error register

       sk
	   the sense key we'll fill out

       asc
	   the additional sense code we'll fill out

       ascq
	   the additional sense code qualifier we'll fill out

       verbose
	   be verbose

DESCRIPTION

       Converts an ATA error into a SCSI error. Fill out pointers to SK, ASC, and ASCQ bytes for later use in fixed or descriptor format sense
       blocks.

LOCKING

       spin_lock_irqsave(host lock)

NAME

       scsi_validate_sense - find descriptor in SCSI sense data

SYNOPSIS

       #include <sys/scsi/scsi.h>

       int scsi_validate_sense(uint8_t *sense_buffer, int sense_buf_len,
	    int *flags);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

       sense_buffer	Pointer to a buffer containing SCSI sense data. The sense data is expected in wire format starting at the response code.

       sense_buf_len	Length of sense buffer in bytes.

       flags		Returns additional properties of the sense data.

DESCRIPTION

       The  scsi_validate_sense() function returns the format of the sense data contained in the provided sense buffer. If the response code field
       in the sense data is not recognized or if there is not enough sense data to include sense key, asc,  and  ascq  then  scsi_validate_sense()
       returns	SENSE_UNUSABLE.  If  the buffer contains usable sense data in fixed format, the function returns SENSE_FIXED_FORMAT. If the buffer
       contains usable sense data in descriptor format, the function returns SENSE_DESCR_FORMAT.

       The following flags may be set as appropriate depending on the sense data:

       SNS_BUF_OVERFLOW    The sense data buffer provided for the request is too small to hold all the sense data.

       SNS_BUF_DEFERRED    The sense data contained in the buffer relates to an error that has occurred during the processing  of  a  successfully
			   completed command, such as a cached write that could not be commited to the media.

RETURN VALUES

       SENSE_UNUSABLE	     The response code from the sense data is unrecognized or not enough sense data present to provide the sense key, asc,
			     and ascq.

       SENSE_FIXED_FORMAT    The sense data in the buffer is in "fixed format".

       SENSE_DESCR_FORMAT    The sense data in the buffer is in "descriptor format".

CONTEXT

       The scsi_validate_sense() function can be called from user or interrupt context.
