This area may be used to hold data or 13707c478bd9Sstevel@tonic-gate * a pointer to a data block that is allocated/freed by the layer's 13717c478bd9Sstevel@tonic-gate * iostart/iodone routines. Allocation & management policy for the 13727c478bd9Sstevel@tonic-gate * layer-private area is defined & implemented by each specific 13737c478bd9Sstevel@tonic-gate * layer as required. 13747c478bd9Sstevel@tonic-gate * 13757c478bd9Sstevel@tonic-gate * IMPORTANT: Since a higher layer may depend on the value in the 13767c478bd9Sstevel@tonic-gate * xb_private field, each layer must ensure that it returns the 13777c478bd9Sstevel@tonic-gate * buf/xbuf to the next higher layer (via SD_NEXT_IODONE()) with 13787c478bd9Sstevel@tonic-gate * the SAME VALUE in xb_private as when the buf/xbuf was first 13797c478bd9Sstevel@tonic-gate * received by the layer's iostart routine. Typically this is done 13807c478bd9Sstevel@tonic-gate * by the iostart routine saving the contents of xb_private into 13817c478bd9Sstevel@tonic-gate * a place in the layer-private data area, and the iodone routine 13827c478bd9Sstevel@tonic-gate * restoring the value of xb_private before deallocating the 13837c478bd9Sstevel@tonic-gate * layer-private data block and calling SD_NEXT_IODONE(). Of course, 13847c478bd9Sstevel@tonic-gate * if a layer never modifies xb_private in a buf/xbuf from a higher 13857c478bd9Sstevel@tonic-gate * layer, there will be no need to restore the value. 13867c478bd9Sstevel@tonic-gate * 13877c478bd9Sstevel@tonic-gate * Note that in the case where a layer _creates_ a buf/xbuf (such as 13887c478bd9Sstevel@tonic-gate * by calling sd_shadow_buf_alloc()) to pass to a lower layer, it is 13897c478bd9Sstevel@tonic-gate * not necessary to preserve the contents of xb_private as there is 13907c478bd9Sstevel@tonic-gate * no higher layer dependency on the value of xb_private. Such a 13917c478bd9Sstevel@tonic-gate * buf/xbuf must be deallocated by the layer that allocated it and 13927c478bd9Sstevel@tonic-gate * must *NEVER* be passed up to a higher layer. 13937c478bd9Sstevel@tonic-gate */ 13947c478bd9Sstevel@tonic-gate void *xb_private; /* Layer-private data block */ 13957c478bd9Sstevel@tonic-gate 13967c478bd9Sstevel@tonic-gate /* 13977c478bd9Sstevel@tonic-gate * We do not use the b_blkno provided in the buf(9S), as we need to 13987c478bd9Sstevel@tonic-gate * make adjustments to it in the driver, but it is not a field that 13997c478bd9Sstevel@tonic-gate * the driver owns or is free to modify. 14007c478bd9Sstevel@tonic-gate */ 14017c478bd9Sstevel@tonic-gate daddr_t xb_blkno; /* Absolute block # on target */ 14029e1c849eSDavid Zhang - Sun Microsystems - Beijing China uint64_t xb_ena; /* ena for a specific SCSI command */ 14037c478bd9Sstevel@tonic-gate 14047c478bd9Sstevel@tonic-gate int xb_chain_iostart; /* iostart side index */ 14057c478bd9Sstevel@tonic-gate int xb_chain_iodone; /* iodone side index */ 14067c478bd9Sstevel@tonic-gate int xb_pkt_flags; /* Flags for scsi_init_pkt() */ 14077c478bd9Sstevel@tonic-gate ssize_t xb_dma_resid; 14087c478bd9Sstevel@tonic-gate short xb_retry_count; 14097c478bd9Sstevel@tonic-gate short xb_victim_retry_count; 14107c478bd9Sstevel@tonic-gate short xb_ua_retry_count; /* unit_attention retry counter */ 141103509b53Slh short xb_nr_retry_count; /* not ready retry counter */ 14127c478bd9Sstevel@tonic-gate 14137c478bd9Sstevel@tonic-gate /* 14147c478bd9Sstevel@tonic-gate * Various status and data used when a RQS command is run on 14157c478bd9Sstevel@tonic-gate * the behalf of this command. 14167c478bd9Sstevel@tonic-gate */ 14177c478bd9Sstevel@tonic-gate struct buf *xb_sense_bp; /* back ptr to buf, for RQS */ 14187c478bd9Sstevel@tonic-gate uint_t xb_sense_state; /* scsi_pkt state of RQS command */ 14197c478bd9Sstevel@tonic-gate ssize_t xb_sense_resid; /* residual of RQS command */ 14207c478bd9Sstevel@tonic-gate uchar_t xb_sense_status; /* scsi status byte of RQS command */ 14217c478bd9Sstevel@tonic-gate uchar_t xb_sense_data[SENSE_LENGTH]; /* sense data from RQS cmd */ 142230ab6db6Slh /* 142330ab6db6Slh * Extra sense larger than SENSE_LENGTH will be allocated 142430ab6db6Slh * right after xb_sense_data[SENSE_LENGTH].
