Allocation & management policy for the 13577c478bd9Sstevel@tonic-gate * layer-private area is defined & implemented by each specific 13587c478bd9Sstevel@tonic-gate * layer as required. 13597c478bd9Sstevel@tonic-gate * 13607c478bd9Sstevel@tonic-gate * IMPORTANT: Since a higher layer may depend on the value in the 13617c478bd9Sstevel@tonic-gate * xb_private field, each layer must ensure that it returns the 13627c478bd9Sstevel@tonic-gate * buf/xbuf to the next higher layer (via SD_NEXT_IODONE()) with 13637c478bd9Sstevel@tonic-gate * the SAME VALUE in xb_private as when the buf/xbuf was first 13647c478bd9Sstevel@tonic-gate * received by the layer's iostart routine. Typically this is done 13657c478bd9Sstevel@tonic-gate * by the iostart routine saving the contents of xb_private into 13667c478bd9Sstevel@tonic-gate * a place in the layer-private data area, and the iodone routine 13677c478bd9Sstevel@tonic-gate * restoring the value of xb_private before deallocating the 13687c478bd9Sstevel@tonic-gate * layer-private data block and calling SD_NEXT_IODONE(). Of course, 13697c478bd9Sstevel@tonic-gate * if a layer never modifies xb_private in a buf/xbuf from a higher 13707c478bd9Sstevel@tonic-gate * layer, there will be no need to restore the value. 13717c478bd9Sstevel@tonic-gate * 13727c478bd9Sstevel@tonic-gate * Note that in the case where a layer _creates_ a buf/xbuf (such as 13737c478bd9Sstevel@tonic-gate * by calling sd_shadow_buf_alloc()) to pass to a lower layer, it is 13747c478bd9Sstevel@tonic-gate * not necessary to preserve the contents of xb_private as there is 13757c478bd9Sstevel@tonic-gate * no higher layer dependency on the value of xb_private. Such a 13767c478bd9Sstevel@tonic-gate * buf/xbuf must be deallocated by the layer that allocated it and 13777c478bd9Sstevel@tonic-gate * must *NEVER* be passed up to a higher layer. 13787c478bd9Sstevel@tonic-gate */ 13797c478bd9Sstevel@tonic-gate void *xb_private; /* Layer-private data block */ 13807c478bd9Sstevel@tonic-gate 13817c478bd9Sstevel@tonic-gate /* 13827c478bd9Sstevel@tonic-gate * We do not use the b_blkno provided in the buf(9S), as we need to 13837c478bd9Sstevel@tonic-gate * make adjustments to it in the driver, but it is not a field that 13847c478bd9Sstevel@tonic-gate * the driver owns or is free to modify. 13857c478bd9Sstevel@tonic-gate */ 13867c478bd9Sstevel@tonic-gate daddr_t xb_blkno; /* Absolute block # on target */ 13877c478bd9Sstevel@tonic-gate 13887c478bd9Sstevel@tonic-gate int xb_chain_iostart; /* iostart side index */ 13897c478bd9Sstevel@tonic-gate int xb_chain_iodone; /* iodone side index */ 13907c478bd9Sstevel@tonic-gate int xb_pkt_flags; /* Flags for scsi_init_pkt() */ 13917c478bd9Sstevel@tonic-gate ssize_t xb_dma_resid; 13927c478bd9Sstevel@tonic-gate short xb_retry_count; 13937c478bd9Sstevel@tonic-gate short xb_victim_retry_count; 13947c478bd9Sstevel@tonic-gate short xb_ua_retry_count; /* unit_attention retry counter */ 13957c478bd9Sstevel@tonic-gate 13967c478bd9Sstevel@tonic-gate /* 13977c478bd9Sstevel@tonic-gate * Various status and data used when a RQS command is run on 13987c478bd9Sstevel@tonic-gate * the behalf of this command. 13997c478bd9Sstevel@tonic-gate */ 14007c478bd9Sstevel@tonic-gate struct buf *xb_sense_bp; /* back ptr to buf, for RQS */ 14017c478bd9Sstevel@tonic-gate uint_t xb_sense_state; /* scsi_pkt state of RQS command */ 14027c478bd9Sstevel@tonic-gate ssize_t xb_sense_resid; /* residual of RQS command */ 14037c478bd9Sstevel@tonic-gate uchar_t xb_sense_status; /* scsi status byte of RQS command */ 14047c478bd9Sstevel@tonic-gate uchar_t xb_sense_data[SENSE_LENGTH]; /* sense data from RQS cmd */ 14057c478bd9Sstevel@tonic-gate }; 14067c478bd9Sstevel@tonic-gate 14077c478bd9Sstevel@tonic-gate _NOTE(SCHEME_PROTECTS_DATA("unique per pkt", sd_xbuf)) 14087c478bd9Sstevel@tonic-gate 14097c478bd9Sstevel@tonic-gate #define SD_PKT_ALLOC_SUCCESS 0 14107c478bd9Sstevel@tonic-gate #define SD_PKT_ALLOC_FAILURE 1 14117c478bd9Sstevel@tonic-gate #define SD_PKT_ALLOC_FAILURE_NO_DMA 2 14127c478bd9Sstevel@tonic-gate #define SD_PKT_ALLOC_FAILURE_PKT_TOO_SMALL 3 14137c478bd9Sstevel@tonic-gate #define SD_PKT_ALLOC_FAILURE_CDB_TOO_SMALL 4 14147c478bd9Sstevel@tonic-gate 14157c478bd9Sstevel@tonic-gate #define SD_GET_XBUF(bp) ((struct sd_xbuf *)((bp)->b_private)) 14167c478bd9Sstevel@tonic-gate #define SD_GET_UN(bp) ((SD_GET_XBUF(bp))->xb_un) 14177c478bd9Sstevel@tonic-gate #define SD_GET_PKTP(bp) ((SD_GET_XBUF(bp))->xb_pktp) 14187c478bd9Sstevel@tonic-gate #define SD_GET_BLKNO(bp) ((SD_GET_XBUF(bp))->xb_blkno) 14197c478bd9Sstevel@tonic-gate 14207c478bd9Sstevel@tonic-gate 14217c478bd9Sstevel@tonic-gate /* 14227c478bd9Sstevel@tonic-gate * Special-purpose struct for sd_send_scsi_cmd() to pass command-specific 14237c478bd9Sstevel@tonic-gate * data through the layering chains to sd_initpkt_for_uscsi(). 14247c478bd9Sstevel@tonic-gate */ 14257c478bd9Sstevel@tonic-gate struct sd_uscsi_info { 14267c478bd9Sstevel@tonic-gate int ui_flags; 14277c478bd9Sstevel@tonic-gate struct uscsi_cmd *ui_cmdp; 1428fa9e4066Sahrens /* 1429fa9e4066Sahrens * ui_dkc is used by sd_send_scsi_SYNCHRONIZE_CACHE() to allow 1430fa9e4066Sahrens * for async completion notification. 1431fa9e4066Sahrens */ 1432fa9e4066Sahrens struct dk_callback ui_dkc; 14337c478bd9Sstevel@tonic-gate }; 14347c478bd9Sstevel@tonic-gate 14357c478bd9Sstevel@tonic-gate _NOTE(SCHEME_PROTECTS_DATA("Unshared data", sd_uscsi_info)) 14367c478bd9Sstevel@tonic-gate 14377c478bd9Sstevel@tonic-gate 14387c478bd9Sstevel@tonic-gate /* 14397c478bd9Sstevel@tonic-gate * Macros and definitions for driver kstats and errstats 14407c478bd9Sstevel@tonic-gate * 14417c478bd9Sstevel@tonic-gate * Some third-party layered drivers (they know who they are) do not maintain 14427c478bd9Sstevel@tonic-gate * their open/close counts correctly which causes our kstat reporting to get 14437c478bd9Sstevel@tonic-gate * messed up & results in panics.
