										 |  |  | Known issues : | 
					
						
							|  |  |  | 	* Please read the associated RELEASE-NOTES file !!! | 
					
						
							|  |  |  | 	* This source release intended for upstream kernel releases only! | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20050323 to 20050413 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.28 | 
					
						
							|  |  |  | 	* Fixed build warning for 2.6.12-rc2 kernels: mempool_alloc now | 
					
						
							|  |  |  | 	  requires a function which takes an unsigned int for gfp_flags. | 
					
						
							|  |  |  | 	* Removed pci dma sync calls to coherent/consistent pci memory. | 
					
						
							|  |  |  | 	* Merged patch from Christoph Hellwig <hch@lst.de>: split helpers | 
					
						
							|  |  |  | 	  for fabric and nport logins out of lpfc_cmpl_els_flogi. | 
					
						
							|  |  |  | 	* Removed sysfs attributes that are used to dump the various | 
					
						
							|  |  |  | 	  discovery lists. | 
					
						
							|  |  |  | 	* Fix for issue where not all luns are seen.  Search all lists | 
					
						
							|  |  |  | 	  other than unmap list in lpfc_find_target().  Otherwise INQUIRY | 
					
						
							|  |  |  | 	  to luns on nodes in NPR or other relevant states (PLOGI, | 
					
						
							|  |  |  | 	  PRLI...) are errored back and scan() terminates. | 
					
						
							|  |  |  | 	* Removed FC_TRANSPORT_PATCHESxxx defines.  They're in 2.6.12-rc1. | 
					
						
							|  |  |  | 	* Compare return value of lpfc_scsi_tgt_reset against SCSI | 
					
						
							|  |  |  | 	  midlayer codes SUCCESS/FAILED which that function returns rather | 
					
						
							|  |  |  | 	  than SLI return code. | 
					
						
							|  |  |  | 	* Removed extraneous calls to lpfc_sli_next_iotag which should | 
					
						
							|  |  |  | 	  only be called from lpfc_sli_submit_iocb.  Also make | 
					
						
							|  |  |  | 	  lpfc_sli_next_iotag static. | 
					
						
							|  |  |  | 	* Added PCI ID for LP10000-S. | 
					
						
							|  |  |  | 	* Changes in lpfc_abort_handler(): Return SUCCESS if we did not | 
					
						
							|  |  |  | 	  find command in both TX and TX completion queues.  Return ERROR | 
					
						
							|  |  |  | 	  if we timed out waiting for command to complete after abort was | 
					
						
							|  |  |  | 	  issued. | 
					
						
							|  |  |  | 	* Zero-out response sense length in lpfc_scsi_prep_cmnd to prevent | 
					
						
							|  |  |  | 	  interpretation of stale sense length when the command completes | 
					
						
							|  |  |  | 	  - was causing spurious 0710 messages. | 
					
						
							|  |  |  | 	* Moved clearing of host_scribble inside host_lock in IO | 
					
						
							|  |  |  | 	  completion path. | 
					
						
							|  |  |  | 	* Fixed a bunch of mixed tab/space indentation. | 
					
						
							|  |  |  | 	* Allow hex format numbers in sysfs attribute setting.  Fix | 
					
						
							|  |  |  | 	  application hang when invalid numbers are used in sysfs | 
					
						
							|  |  |  | 	  settings. | 
					
						
							|  |  |  | 	* Removed extra iotag allocation by lpfc_abort_handler. | 
					
						
							|  |  |  | 	* Clear host_scribble in the scsi_cmnd structure when failing in | 
					
						
							|  |  |  | 	  queuecommand. | 
					
						
							|  |  |  | 	* Changed logic at top of lpfc_abort_handler so that if the | 
					
						
							|  |  |  | 	  command's host_scibble field is NULL, return SUCCESS because the | 
					
						
							|  |  |  | 	  driver has already returned the command to the midlayer. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20050308 to 20050323 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.27 | 
					
						
							|  |  |  | 	* Changed a few lines from patch submitted by Christoph Hellwig | 
					
						
							|  |  |  | 	  (3/19). MAILBOX_WSIZE * (uint32_t) is replaced with an | 
					
						
							|  |  |  | 	  equivalent MAILBOX_CMDSIZE macro. | 
					
						
							|  |  |  | 	* Merged patch from Christoph Hellwig (3/19): some misc patches | 
					
						
							|  |  |  | 	  against the latest drivers: | 
					
						
							|  |  |  | 	  - stop using volatile.  if you need special ordering use memory | 
					
						
							|  |  |  | 	    barriers but that doesn't seem to be the case here | 
					
						
							|  |  |  | 	  - switch lpfc_sli_pcimem_bcopy to take void * arguments. | 
					
						
							|  |  |  | 	  - remove typecast for constants - a U postfix marks them | 
					
						
							|  |  |  | 	    unsigned int in C | 
					
						
							|  |  |  | 	  - add a MAILBOX_CMD_SIZE macro, as most users of | 
					
						
							|  |  |  | 	    MAILBOX_CMD_WSIZE didn't really want the word count | 
					
						
							|  |  |  | 	  - kill struct lpfc_scsi_dma_buf and embedded the two members | 
					
						
							|  |  |  | 	    directly in struct lpfc_scsi_buf | 
					
						
							|  |  |  | 	  - don't call dma_sync function on allocations from | 
					
						
							|  |  |  | 	    pci_pool_alloc - it's only for streaming mappings (pci_map_*) | 
					
						
							|  |  |  | 	* Merged patch from Christoph Hellwig (3/19) - nlp_failMask isn't | 
					
						
							|  |  |  | 	  ever used by the driver, just reported to userspace (and that in | 
					
						
							|  |  |  | 	  a multi-value file which is against the sysfs guidelines). | 
					
						
							|  |  |  | 	* Change pci_module_init to pci_register_module() with appropriate | 
					
						
							|  |  |  | 	  ifdefs. | 
					
						
							|  |  |  | 	* Added #include <linux/dma-mapping.h> as required by the DMA | 
					
						
							|  |  |  | 	  32bit and 64bit defines on some archs. | 
					
						
							|  |  |  | 	* Merged patch from Christoph Hellwig (03/19) - fix initialization | 
					
						
							|  |  |  | 	  order - scsi_add_host must happen last from scsi POV. Also some | 
					
						
							|  |  |  | 	  minor style/comment fixups. | 
					
						
							|  |  |  | 	* Fixed use of TRANSPORT_PATCHES_V2 by changing to | 
					
						
							|  |  |  | 	  FC_TRANSPORT_PATCHES_V2. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20050223 to 20050308 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.26 | 
					
						
							|  |  |  | 	* Revise TRANSPORT_PATCHES_V2 so that lpfc_target is removed and | 
					
						
							|  |  |  | 	  rport data is used instead. Removed device_queue_hash[]. | 
					
						
							|  |  |  | 	* Changed RW attributes of scan_down, max_luns and fcp_bind_method | 
					
						
							|  |  |  | 	  to R only. | 
					
						
							|  |  |  | 	* Fixed RSCN handling during initial link initialization. | 
					
						
							|  |  |  | 	* Fixed issue with receiving PLOGI handling when node is on NPR | 
					
						
							|  |  |  | 	  list and marked for ADISC. | 
					
						
							|  |  |  | 	* Fixed RSCN timeout issues. | 
					
						
							|  |  |  | 	* Reduced severity of "SCSI layer issued abort device" message to | 
					
						
							|  |  |  | 	  KERN_WARNING. | 
					
						
							|  |  |  | 	* Feedback from Christoph Hellwig (on 2/5) - In the LPFC_EVT_SCAN | 
					
						
							|  |  |  | 	  case the caller already has the target ID handly, so pass that | 
					
						
							|  |  |  | 	  one in evt_arg1. | 
					
						
							|  |  |  | 	* Fix compile warning/resultant panic in | 
					
						
							|  |  |  | 	  lpfc_register_remote_port(). | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20050215 to 20050223 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.25 | 
					
						
							|  |  |  | 	* Add appropriate comments to lpfc_sli.c. | 
					
						
							|  |  |  | 	* Use DMA_64BIT_MASK and DMA_32BIT_MASK defines instead of | 
					
						
							|  |  |  | 	  0xffffffffffffffffULL & 0xffffffffULL respectively.  Use pci | 
					
						
							|  |  |  | 	  equivalents instead of dma_set_mask and also modify condition | 
					
						
							|  |  |  | 	  clause to actually exit on error condition. | 
					
						
							|  |  |  | 	* Restart els timeout handler only if txcmplq_cnt. On submission, | 
					
						
							|  |  |  | 	  mod_timer the els_tmofunc.  This prevents the worker thread from | 
					
						
							|  |  |  | 	  waking up the els_tmo handler un-necessarily.  The thread was | 
					
						
							|  |  |  | 	  being woken up even when there were no pending els commands. | 
					
						
							|  |  |  | 	* Added new typedefs for abort and reset functions. | 
					
						
							|  |  |  | 	* Collapsed lpfc_sli_abort_iocb_xxx into a single function. | 
					
						
							|  |  |  | 	* Collapsed lpfc_sli_sum_iocb_xxx into a single function. | 
					
						
							|  |  |  | 	* Removed TXQ from all abort and reset handlers since it is never | 
					
						
							|  |  |  | 	  used. | 
					
						
							|  |  |  | 	* Fixed Oops panic in 8.0.23 (reported on SourceForge).  The | 
					
						
							|  |  |  | 	  driver was not handling LPFC_IO_POLL cases correctly in | 
					
						
							|  |  |  | 	  fast_ring_event and was setting the tgt_reset timeout to 0 in | 
					
						
							|  |  |  | 	  lpfc_reset_bus_handler.  This 0 timeout would not allow the FW | 
					
						
							|  |  |  | 	  to timeout ABTS's on bad targets and allow the driver to have an | 
					
						
							|  |  |  | 	  iocb on two lists.  Also split the lpfc_sli_ringtxcmpl_get | 
					
						
							|  |  |  | 	  function into two routines to match the fast and slow completion | 
					
						
							|  |  |  | 	  semantics - ELS completions worked for the wrong reasons.  Also | 
					
						
							|  |  |  | 	  provided new log message number - had two 0326 entries. | 
					
						
							|  |  |  | 	* Removed unused #define LPFC_SCSI_INITIAL_BPL_SIZE. | 
					
						
							|  |  |  | 	* Removed unused struct lpfc_node_farp_pend definition. | 
					
						
							|  |  |  | 	* Removed unused #define LPFC_SLIM2_PAGE_AREA. | 
					
						
							|  |  |  | 	* Changed zeros used as pointers to NULL. | 
					
						
							|  |  |  | 	* Removed unneeded braces around single line in lpfc_do_work. | 
					
						
							|  |  |  | 	* Close humongous memory leak in lpfc_sli.c - driver was losing 13 | 
					
						
							|  |  |  | 	  iocbq structures per LIP. | 
					
						
							|  |  |  | 	* Removed last of GFP_ATOMIC allocations. | 
					
						
							|  |  |  | 	* Locks are not taken outside of nportdisc, hbadisc, els and most | 
					
						
							|  |  |  | 	  of the init, sli, mbox and ct groups of functions | 
					
						
							|  |  |  | 	* Fix comment for lpfc_sli_iocb_cmd_type to fit within 80 columns. | 
					
						
							|  |  |  | 	* Replaced wait_event() with wait_event_interruptible(). | 
					
						
							|  |  |  | 	  wait_event() puts the woker thread in an UNINTERRUPTIBLE state | 
					
						
							|  |  |  | 	  causing it to figure in load average calculations. Also add a | 
					
						
							|  |  |  | 	  BUG_ON to the ret code of wait_event_interruptible() since the | 
					
						
							|  |  |  | 	  premise is that the worker thread is signal-immune. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20050208 to 20050215 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.24 | 
					
						
							|  |  |  | 	* Fixed a memory leak of iocbq structure.  For ELS solicited iocbs | 
					
						
							|  |  |  | 	  sli layer now frees the response iocbs after processing it. | 
					
						
							|  |  |  | 	* Closed large memory leak -- we were losing 13 iocbq structures | 
					
						
							|  |  |  | 	  per LIP. | 
					
						
							|  |  |  | 	* Changing EIO and ENOMEM to -EIO and -ENOMEM respectively. | 
					
						
							|  |  |  | 	* Cleanup of lpfc_sli_iocb_cmd_type array and typing of iocb type. | 
					
						
							|  |  |  | 	* Implemented Christoph Hellwig's feedback from 02/05: Remove | 
					
						
							|  |  |  | 	  macros putLunHigh, putLunLow. Use lpfc_put_lun() inline instead. | 
					
						
							|  |  |  | 	* Integrated Christoph Hellwig's feedback from 02/05: Instead of | 
					
						
							|  |  |  | 	  cpu_to_be32(), use swab16((uint16_t)lun). This is the same as | 
					
						
							|  |  |  | 	  "swab16() on LE" and "<<16 on BE". | 
					
						
							|  |  |  | 	* Added updates for revised FC remote port patch (dev_loss_tmo | 
					
						
							|  |  |  | 	  moved to rport, hostdata renamed dd_data, add fc_remote_host() | 
					
						
							|  |  |  | 	  on shutdown). | 
					
						
							|  |  |  | 	* Removed unnecessary function prototype. | 
					
						
							|  |  |  | 	* Added code to prevent waking up worker thread after the exit of | 
					
						
							|  |  |  | 	  worker thread.  Fixes panic seen with insmod/rmmod testing with | 
					
						
							|  |  |  | 	  70 disks. | 
					
						
							|  |  |  | 	* Integrated Christoph Hellwig's patch from 1/30: Make some | 
					
						
							|  |  |  | 	  variables/code static (namely lpfcAlpaArray and | 
					
						
							|  |  |  | 	  process_nodev_timeout()). | 
					
						
							|  |  |  | 	* Integrated Christoph Hellwig's patch from 1/30: Use | 
					
						
							|  |  |  | 	  switch...case instead of if...else if...else if while decoding | 
					
						
							|  |  |  | 	  JDEC id. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20050201 to 20050208 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.23 | 
					
						
							|  |  |  | 	* Make lpfc_work_done, lpfc_get_scsi_buf, | 
					
						
							|  |  |  | 	  lpfc_mbx_process_link_up, lpfc_mbx_issue_link_down and | 
					
						
							|  |  |  | 	  lpfc_sli_chipset_init static. | 
					
						
							|  |  |  | 	* Cleaned up references to list_head->next field in the driver. | 
					
						
							|  |  |  | 	* Replaced lpfc_discq_post_event with lpfc_workq_post_event. | 
					
						
							|  |  |  | 	* Implmented Christoph Hellwig's review from 2/5: Check for return | 
					
						
							|  |  |  | 	  values of kmalloc. | 
					
						
							|  |  |  | 	* Integrated Christoph Hellwig's patch from 1/30: Protecting | 
					
						
							|  |  |  | 	  scan_tmo and friends in !FC_TRANSPORT_PATCHES_V2 && | 
					
						
							|  |  |  | 	  !USE_SCAN_TARGET. | 
					
						
							|  |  |  | 	* Integrated Christoph Hellwig's patch from 1/30: Some fixes in | 
					
						
							|  |  |  | 	  the evt handling area. | 
					
						
							|  |  |  | 	* Integrated Christoph Hellwig's patch from 1/30: Remove usage of | 
					
						
							|  |  |  | 	  intr_inited variable. The interrupt initilization from OS side | 
					
						
							|  |  |  | 	  now happens in lpfc_probe_one(). | 
					
						
							|  |  |  | 	* Integrated Christoph Hellwig's patch from 1/30: remove shim | 
					
						
							|  |  |  | 	  lpfc_alloc_transport_attr - remove shim lpfc_alloc_shost_attrs - | 
					
						
							|  |  |  | 	  remove shim lpfc_scsi_host_init - allocate phba mem in scsi's | 
					
						
							|  |  |  | 	  hostdata readjust code so that they are no use after free's | 
					
						
							|  |  |  | 	  (don't use after scsi_host_put) - make lpfc_alloc_sysfs_attr | 
					
						
							|  |  |  | 	  return errors | 
					
						
							|  |  |  | 	* Fixed panic in lpfc_probe_one(). Do not delete in a list | 
					
						
							|  |  |  | 	  iterator that is not safe. | 
					
						
							|  |  |  | 	* Clean up fast lookup array of the fcp_ring when aborting iocbs. | 
					
						
							|  |  |  | 	* Following timeout handlers moved to the lpfc worker thread: | 
					
						
							|  |  |  | 	  lpfc_disc_timeout, lpfc_els_timeout, lpfc_mbox, lpfc_fdmi_tmo, | 
					
						
							|  |  |  | 	  lpfc_nodev_timeout, lpfc_els_retry_delay. | 
					
						
							|  |  |  | 	* Removed unused NLP_NS_NODE #define. | 
					
						
							|  |  |  | 	* Integrated Christoph Hellwig's patch from 1/30: remove unused | 
					
						
							|  |  |  | 	  lpfc_hba_list; remove unused lpfc_rdrev_wd30; remove | 
					
						
							|  |  |  | 	  lpfc_get_brd_no and use Linux provided IDR. | 
					
						
							|  |  |  | 	* Changed board reset procedure so that lpfc_sli_send_reset() | 
					
						
							|  |  |  | 	  writes the INITFF bit and leaves lpfc_sli_brdreset() to clear | 
					
						
							|  |  |  | 	  the bit. | 
					
						
							|  |  |  | 	* Removed outfcpio sysfs device attribute. | 
					
						
							|  |  |  | 	* VPD changes: 1) Modify driver to use the model name and | 
					
						
							|  |  |  | 	  description from the VPD data if it exists 2) Rework use of DUMP | 
					
						
							|  |  |  | 	  mailbox command to support HBAs with 256 bytes of SLIM. | 
					
						
							|  |  |  | 	* Fixed compile error for implicit definition of struct | 
					
						
							|  |  |  | 	  scsi_target | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20050124 to 20050201 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.22 | 
					
						
							|  |  |  | 	* Moved discovery timeout handler to worker thread. There are | 
					
						
							|  |  |  | 	  function calls in this function which are not safe to call from | 
					
						
							|  |  |  | 	  HW interrupt context. | 
					
						
							|  |  |  | 	* Removed free_irq from the error path of HBA initialization. | 
					
						
							|  |  |  | 	  This will fix the free of uninitialised IRQ when config_port | 
					
						
							|  |  |  | 	  fails. | 
					
						
							|  |  |  | 	* Make sure function which processes unsolicited IOCBs on ELS ring | 
					
						
							|  |  |  | 	  still is called with the lock held. | 
					
						
							|  |  |  | 	* Clear LA bit from work_ha when we are not supposed to handle LA. | 
					
						
							|  |  |  | 	* Fix double locking bug in the error handling part of | 
					
						
							|  |  |  | 	  lpfc_mbx_cmpl_read_la. | 
					
						
							|  |  |  | 	* Implemented fast IOCB processing for FCP ring. | 
					
						
							|  |  |  | 	* Since mboxes are now unconditionally allocated outside of the | 
					
						
							|  |  |  | 	  lock, free them in cases where they are not used. | 
					
						
							|  |  |  | 	* Moved out a couple of GFP_ATOMICs in lpfc_disc_timeout, to | 
					
						
							|  |  |  | 	  before locks so that they can GFP_KERNEL instead. Also cleaned | 
					
						
							|  |  |  | 	  up code. | 
					
						
							|  |  |  | 	* Collapsed interrupt handling code into one function. | 
					
						
							|  |  |  | 	* Removed event posting and handling of solicited and unsolicited | 
					
						
							|  |  |  | 	  iocbs. | 
					
						
							|  |  |  | 	* Remove ELS ring handling leftovers from the lpfc_sli_inter(). | 
					
						
							|  |  |  | 	* ELS ring (any slow ring) moved from the lpfc_sli_inter() into a | 
					
						
							|  |  |  | 	  worker thread.  Link Attention, Mbox Attention, and Error | 
					
						
							|  |  |  | 	  Attention, as well as slow rings' attention is passed to the | 
					
						
							|  |  |  | 	  worker thread via worker thread copy of Host Attention | 
					
						
							|  |  |  | 	  register. Corresponding events are removed from the event queue | 
					
						
							|  |  |  | 	  handling. | 
					
						
							|  |  |  | 	* Add entries to hba structure to delegate some functionality from | 
					
						
							|  |  |  | 	  the lpfc_sli_inter() to a worker thread. | 
					
						
							|  |  |  | 	* Reduced used of GFP_ATOMIC for memory allocations. | 
					
						
							|  |  |  | 	* Moved locks deeper in order to change GFP_ATOMIC to GFP_KERNEL. | 
					
						
							|  |  |  | 	* IOCB initialization fix for Raw IO. | 
					
						
							|  |  |  | 	* Removed qcmdcnt, iodonecnt, errcnt from lpfc_target and from | 
					
						
							|  |  |  | 	  driver. | 
					
						
							|  |  |  | 	* Added call to lpfc_els_abort in lpfc_free_node.  Modified | 
					
						
							|  |  |  | 	  lpfc_els_abort to reset txq and txcmplq iterator after a | 
					
						
							|  |  |  | 	  iocb_cmpl call. | 
					
						
							|  |  |  | 	* Fixed a use after free issue in lpfc_init.c. | 
					
						
							|  |  |  | 	* Defined default mailbox completion routine and removed code in | 
					
						
							|  |  |  | 	  the sli layer which checks the mbox_cmpl == 0 to free mail box | 
					
						
							|  |  |  | 	  resources. | 
					
						
							|  |  |  | 	* In lpfc_workq_post_event, clean up comment formatting and remove | 
					
						
							|  |  |  | 	  unneeded cast of kmalloc's return. | 
					
						
							|  |  |  | 	* Removed loop which calls fc_remote_port_unblock and | 
					
						
							|  |  |  | 	  fc_remote_port_delete for every target as this same effect is | 
					
						
							|  |  |  | 	  accomplished by the scsi_remove_host call. | 
					
						
							|  |  |  | 	* Minor cleanup of header files.  Stop header files including | 
					
						
							|  |  |  | 	  other header files.  Removed sentinels which hide multiple | 
					
						
							|  |  |  | 	  inclusions.  Removed unneeded #include directives. | 
					
						
							|  |  |  | 	* Fixed memory leaks in mailbox error paths. | 
					
						
							|  |  |  | 	* Moved lock from around of lpfc_work_done to lpfc_work_done | 
					
						
							|  |  |  | 	  itself. | 
					
						
							|  |  |  | 	* Removed typedef for LPFC_WORK_EVT_t and left just struct | 
					
						
							|  |  |  | 	  lpfc_work_evt to comply with linux_scsi review coding style. | 
					
						
							|  |  |  | 	* Fixed some trailing whitespaces, spaces used for indentation and | 
					
						
							|  |  |  | 	  ill-formatting multiline comments. | 
					
						
							|  |  |  | 	* Bug fix for Raw IO errors.  Reuse of IOCBs now mandates setting | 
					
						
							|  |  |  | 	  of ulpPU and fcpi_parm to avoid incorrect read check of Write IO | 
					
						
							|  |  |  | 	  and incorrect read length. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20050110 to 20050124 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.21 | 
					
						
							|  |  |  | 	* Removed unpleasant casting in the definition and use of | 
					
						
							|  |  |  | 	  lpfc_disc_action function pointer array. | 
					
						
							|  |  |  | 	* Makefile cleanup.  Use ?= operator for setting default | 
					
						
							|  |  |  | 	  KERNELVERSION and BASEINCLUDE values.  Use $(PWD) consistently. | 
					
						
							|  |  |  | 	* Removed call to lpfc_sli_intr from lpfc_config_port_post.  All | 
					
						
							|  |  |  | 	  Linux systems will service hardware interrupts while bringing up | 
					
						
							|  |  |  | 	  the driver. | 
					
						
							|  |  |  | 	* Christoph Hellwig change request: Reorg of contents of | 
					
						
							|  |  |  | 	  lpfc_hbadisc.c, lpfc_scsi.h, lpfc_init.c, lpfc_sli.c, | 
					
						
							|  |  |  | 	  lpfc_attr.c, lpfc_scsi.c. | 
					
						
							|  |  |  | 	* Renamed discovery thread to lpfc_worker thread.  Moved handling | 
					
						
							|  |  |  | 	  of error attention and link attention and mbox event handler to | 
					
						
							|  |  |  | 	  lpfc_worker thread. | 
					
						
							|  |  |  | 	* Removed .proc_info and .proc_name from the driver template and | 
					
						
							|  |  |  | 	  associated code. | 
					
						
							|  |  |  | 	* Removed check of FC_UNLOADING flag in lpfc_queuecommand to | 
					
						
							|  |  |  | 	  determine what result to return. | 
					
						
							|  |  |  | 	* Move modification of FC_UNLOADING flag under host_lock. | 
					
						
							|  |  |  | 	* Fix IOERR_RCV_BUFFER_WAITING handling for CT and ELS subsystem. | 
					
						
							|  |  |  | 	* Workaround firmware bug for IOERR_RCV_BUFFER_WAITING on ELS | 
					
						
							|  |  |  | 	  ring. | 
					
						
							|  |  |  | 	* Fixed a couple lpfc_post_buffer problems in lpfc_init.c. | 
					
						
							|  |  |  | 	* Add missing spaces to the parameter descriptions for | 
					
						
							|  |  |  | 	  lpfc_cr_delay, lpfc_cr_count and lpfc_discovery_threads. | 
					
						
							|  |  |  | 	* Lock before calling lpfc_sli_hba_down(). | 
					
						
							|  |  |  | 	* Fix leak of "host" in the error path in the remove_one() path. | 
					
						
							|  |  |  | 	* Fix comment for lpfc_cr_count.  It defaults to 1. | 
					
						
							|  |  |  | 	* Fix issue where we are calling lpfc_disc_done() recursively from | 
					
						
							|  |  |  | 	  lpfc_linkdown(), but list_for_each_entry_safe() is not safe for | 
					
						
							|  |  |  | 	  such use. | 
					
						
							|  |  |  | 	* Bump lpfc_discovery_threads (count of outstading ELS commands in | 
					
						
							|  |  |  | 	  discovery) to 32 | 
					
						
							|  |  |  | 	* If the SCSI midlayer tries to recover from an error on a lun | 
					
						
							|  |  |  | 	  while the corresponding target is in the NPR state, lpfc driver | 
					
						
							|  |  |  | 	  will reject all the resets. This will cause the target to be | 
					
						
							|  |  |  | 	  moved to offline state and block all the I/Os. The fix for this | 
					
						
							|  |  |  | 	  is to delay the lun reset to a target which is not in MAPPED | 
					
						
							|  |  |  | 	  state until the target is rediscovered or nodev timeout is | 
					
						
							|  |  |  | 	  fired. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20041229 to 20050110 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.20 | 
					
						
							|  |  |  | 	* rport fix: use new fc_remote_port_rolechg() function instead of | 
					
						
							|  |  |  | 	  direct structure change | 
					
						
							|  |  |  | 	* rport fix: last null pointer check | 
					
						
							|  |  |  | 	* Phase II of GFP_ATOMIC effort.  Replaced iocb_mem_pool and | 
					
						
							|  |  |  | 	  scsibuf_mem_pool with kmalloc and linked list.  Inserted list | 
					
						
							|  |  |  | 	  operations for mempool_alloc calls.  General code cleanup.  All | 
					
						
							|  |  |  | 	  abort and reset routines converted.  Handle_ring_event | 
					
						
							|  |  |  | 	  converted. | 
					
						
							|  |  |  | 	* If the mbox_cmpl == lpfc_sli_wake_mbox_wait in | 
					
						
							|  |  |  | 	  lpfc_sli_handle_mb_event, pmb->context1 points to a waitq. Do | 
					
						
							|  |  |  | 	  not free the structure. | 
					
						
							|  |  |  | 	* rport fixes: fix for rmmod crash | 
					
						
							|  |  |  | 	* rport fixes: when receiving PRLI's, set node/rport role values | 
					
						
							|  |  |  | 	* rport fixes: fix for unload and for fabric port deletes | 
					
						
							|  |  |  | 	* VPD info bug fix. | 
					
						
							|  |  |  | 	* lpfc_linkdown() should be able to process all outstanding events | 
					
						
							|  |  |  | 	  by calling lpfc_disc_done() even if it is called from | 
					
						
							|  |  |  | 	  lpfc_disc_done() Moving all events from phba->dpc_disc to local | 
					
						
							|  |  |  | 	  local_dpc_disc prevents those events from being processed. | 
					
						
							|  |  |  | 	  Removing that queue. From now on we should not see "Illegal | 
					
						
							|  |  |  | 	  State Transition" messages. | 
					
						
							|  |  |  | 	* Release host lock and enable interrupts when calling | 
					
						
							|  |  |  | 	  del_timer_sync() | 
					
						
							|  |  |  | 	* All related to rports: Clean up issues with rport deletion | 
					
						
							|  |  |  | 	  Convert to using block/unblock on list remove (was del/add) | 
					
						
							|  |  |  | 	  Moved rport delete to freenode - so rport tracks node. | 
					
						
							|  |  |  | 	* rport fixes: for fport, get maxframe and class support | 
					
						
							|  |  |  | 	  information | 
					
						
							|  |  |  | 	* Added use of wait_event to work with kthread interface. | 
					
						
							|  |  |  | 	* Ensure that scsi_transport_fc.h is always pulled in by | 
					
						
							|  |  |  | 	  lpfc_scsiport.c | 
					
						
							|  |  |  | 	* In remote port changes: no longer nulling target->pnode when | 
					
						
							|  |  |  | 	  removing from mapped list. Pnode get nulled when the node is | 
					
						
							|  |  |  | 	  freed (after nodev tmo). This bug was causing i/o recieved in | 
					
						
							|  |  |  | 	  the small window while the device was blocked to be errored w/ | 
					
						
							|  |  |  | 	  did_no_connect. With the fix, it returns host_busy | 
					
						
							|  |  |  | 	  (per the pre-remote port changes). | 
					
						
							|  |  |  | 	* Merge in support for fc transport remote port use. This removes | 
					
						
							|  |  |  | 	  any consistent bindings within the driver. All scanning is now | 
					
						
							|  |  |  | 	  on a per-target basis driven by the discovery engine. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20041220 to 20041229 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.19 | 
					
						
							|  |  |  | 	* Fixed bug for handling RSCN type 3.  Terminate RSCN mode | 
					
						
							|  |  |  | 	  properly after ADISC handling completes. | 
					
						
							|  |  |  | 	* Add list_remove_head macro.  Macro cleans up memory allocation | 
					
						
							|  |  |  | 	  list handling.  Also clean up lpfc_reset_bus_handler - routine | 
					
						
							|  |  |  | 	  does not need to allocate its own scsi_cmnd and scsi_device | 
					
						
							|  |  |  | 	  structures. | 
					
						
							|  |  |  | 	* Fixed potential discovery bug, nlp list corrutpion fix potential | 
					
						
							|  |  |  | 	  memory leak | 
					
						
							|  |  |  | 	* Part 1 of the memory allocation rework request by linux-scsi. | 
					
						
							|  |  |  | 	  This effort fixes the number of bdes per scsi_buf to 64, makes | 
					
						
							|  |  |  | 	  the scatter-gather count a module parameter, builds a linked | 
					
						
							|  |  |  | 	  list of scsi_bufs, and removes all dependencies on lpfc_mem.h. | 
					
						
							|  |  |  | 	* Reverted lpfc_do_dpc, probe_one, remove_one to original | 
					
						
							|  |  |  | 	  implementation.  Too many problems (driver not completing | 
					
						
							|  |  |  | 	  initial discovery, and IO not starting to disks).  Backs out | 
					
						
							|  |  |  | 	  kthread patch. | 
					
						
							|  |  |  | 	* Fix race condition in lpfc_do_dpc.  If wake_up interrupt occurs | 
					
						
							|  |  |  | 	  while lpfc_do_dpc is running disc_done and the dpc list is | 
					
						
							|  |  |  | 	  empty, the latest insertion is missed and the schedule_timeout | 
					
						
							|  |  |  | 	  does not wakeup.  The sleep interval is MAX_SCHEDULE_TIMEOUT | 
					
						
							|  |  |  | 	  defined as ~0UL >> 1, a very large number.  Hacked it to 5*HZ | 
					
						
							|  |  |  | 	  for now. | 
					
						
							|  |  |  | 	* Fixed bug introduced when discovery thread implementation was | 
					
						
							|  |  |  | 	  moved to kthread. kthread_stop() is not able to wake up thread | 
					
						
							|  |  |  | 	  waiting on a semaphore and "modprobe -r lpfc" is not always | 
					
						
							|  |  |  | 	  (most of the times) able to complete. Fix is in not using | 
					
						
							|  |  |  | 	  semaphore for the interruptable sleep. | 
					
						
							|  |  |  | 	* Small Makefile cleanup - Remove remnants of 2.4 vs. 2.6 | 
					
						
							|  |  |  | 	  determination. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20041213 to 20041220 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.18 | 
					
						
							|  |  |  | 	* Janitorial cleanup after removal of sliinit and ringinit[] ring | 
					
						
							|  |  |  | 	  statistic is owned by the ring and SLI stats are in sli | 
					
						
							|  |  |  | 	  structure. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig <hch@lst.de> Kill | 
					
						
							|  |  |  | 	  compile warnings on 64 bit platforms: %variables for %llx format | 
					
						
							|  |  |  | 	  specifiers must be caste to long long because %(u)int64_t can | 
					
						
							|  |  |  | 	  just be long on 64bit platforms. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig <hch@lst.de> Removes | 
					
						
							|  |  |  | 	  dead code. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig <hch@lst.de>: use | 
					
						
							|  |  |  | 	  kthread interface. | 
					
						
							|  |  |  | 	* Print LPFC_MODULE_DESC banner in module init routine. | 
					
						
							|  |  |  | 	* Removed sliinit structure and ringinit[] array. | 
					
						
							|  |  |  | 	* Changed log message number from 324 to 326 in lpfc_sli.c. | 
					
						
							|  |  |  | 	* Wait longer for commands to complete in lpfc_reset_bus_handler | 
					
						
							|  |  |  | 	  and lpfc_reset_bus_handler.  Also use schedule_timeout() instead | 
					
						
							|  |  |  | 	  of msleep() and add error message in lpfc_abort_handler() | 
					
						
							|  |  |  | 	* When setting lpfc_nodev_tmo, from dev_loss set routine, make 1 | 
					
						
							|  |  |  | 	  sec minimum value. | 
					
						
							|  |  |  | 	* Functions which assume lock being held were called without lock | 
					
						
							|  |  |  | 	  and kernel complained about unlocking lock which is not locked. | 
					
						
							|  |  |  | 	* Added code in linkdown to unreg if we know login session will be | 
					
						
							|  |  |  | 	  terminated. | 
					
						
							|  |  |  | 	* Removed automap config parameter and fixed up use_adisc logic to | 
					
						
							|  |  |  | 	  include FCP2 devices. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20041207 to 20041213 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.17 | 
					
						
							|  |  |  | 	* Fix sparse warnings by adding __iomem markers to lpfc_compat.h. | 
					
						
							|  |  |  | 	* Fix some sparse warnings -- 0 used as NULL pointer. | 
					
						
							|  |  |  | 	* Make sure there's a space between every if and it's (. | 
					
						
							|  |  |  | 	* Fix some overly long lines and make sure hard tabs are used for | 
					
						
							|  |  |  | 	  indentation. | 
					
						
							|  |  |  | 	* Remove all trailing whitespace. | 
					
						
							|  |  |  | 	* Integrate Christoph Hellwig's patch for 8.0.14: if | 
					
						
							|  |  |  | 	  pci_module_init fails we need to release the transport template. | 
					
						
							|  |  |  |  	  (also don't print the driver name at startup, linux drivers can | 
					
						
							|  |  |  | 	  be loaded without hardware present, and noise in the log for | 
					
						
							|  |  |  | 	  that case is considered unpolite, better print messages only for | 
					
						
							|  |  |  | 	  hardware actually found). | 
					
						
							|  |  |  | 	* Integrate Christoph Hellwig's patch for 8.0.14: Add missing | 
					
						
							|  |  |  | 	  __iomem annotations, remove broken casts, mark functions static. | 
					
						
							|  |  |  | 	  Only major changes is chaning of some offsets from word-based to | 
					
						
							|  |  |  | 	  byte-based so we cans simply do void pointer arithmetics (gcc | 
					
						
							|  |  |  | 	  extension) instead of casting to uint32_t. | 
					
						
							|  |  |  | 	* Integrate Christoph Hellwig's patch for 8.0.14: flag is always | 
					
						
							|  |  |  | 	  LPFC_SLI_ABORT_IMED, aka 0 - remove dead code. | 
					
						
							|  |  |  | 	* Modified preprocessor #ifdef, #if, #ifndef to reflect upstream | 
					
						
							|  |  |  | 	  kernel submission.  Clean build with make clean;make and make | 
					
						
							|  |  |  | 	  clean;make ADVANCED=1 on SMP x86, 2.6.10-rc2 on RHEL 4 Beta | 
					
						
							|  |  |  | 	  1. IO with a few lips and a long cable pull behaved accordingly. | 
					
						
							|  |  |  | 	* Implement full VPD support. | 
					
						
							|  |  |  | 	* Abort handler will try to wait for abort completion before | 
					
						
							|  |  |  | 	  returning.  Fixes some panics in iocb completion code path. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20041130 to 20041207 | 
					
						
							|  |  |  | 	 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.16 | 
					
						
							|  |  |  | 	* Hung dt session fix.  When the midlayer calls to abort a scsi | 
					
						
							|  |  |  | 	  command, make sure the driver does not complete post-abort | 
					
						
							|  |  |  | 	  handler.  Just NULL the iocb_cmpl callback handler and let SLI | 
					
						
							|  |  |  | 	  take over. | 
					
						
							|  |  |  | 	* Add Read check that uses SLI option to validate all READ data | 
					
						
							|  |  |  | 	  actually received. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20041123 to 20041130 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.15 | 
					
						
							|  |  |  | 	* Ifdef'd unused "binary" attributes by DFC_DEBUG for clean | 
					
						
							|  |  |  | 	  compiles | 
					
						
							|  |  |  | 	* Stop DID_ERROR from showing up along with QUEUE_FULL set by the | 
					
						
							|  |  |  | 	  Clarion array (SCSI error ret. val.  0x70028) There is no need | 
					
						
							|  |  |  | 	  for driver to hard fail command which was failed by the target | 
					
						
							|  |  |  | 	  device. | 
					
						
							|  |  |  | 	* Fix for Scsi device scan bug reported on SourceForge.  Driver | 
					
						
							|  |  |  | 	  was returning a DID_ERROR in lpfc_handle_fcp_error causing | 
					
						
							|  |  |  | 	  midlayer to mark report luns as failing even though it | 
					
						
							|  |  |  | 	  succeeded. | 
					
						
							|  |  |  | 	* Don't ignore SCSI status on underrun conditions for inquiries, | 
					
						
							|  |  |  | 	  test unit ready's, etc.  This was causing us to lose | 
					
						
							|  |  |  | 	  reservation conflicts, etc | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20041018 to 20041123 | 
					
						
							|  |  |  | 	 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.14 | 
					
						
							|  |  |  | 	* Added new function "iterator" lpfc_sli_next_iocb_slot() which | 
					
						
							|  |  |  | 	  returns pointer to iocb entry at cmdidx if queue is not full. | 
					
						
							|  |  |  | 	  It also updates next_cmdidx, and local_getidx (but not cmdidx) | 
					
						
							|  |  |  | 	* lpfc_sli_submit_iocb() copies next_cmdidx into cmdidx. Now it is | 
					
						
							|  |  |  | 	  the only place were we are updating cmdidx. | 
					
						
							|  |  |  | 	* lpfc_sli_update_ring() is split in to two -- | 
					
						
							|  |  |  | 	  lpfc_sli_update_ring() and lpfc_sli_update_full_ring(). | 
					
						
							|  |  |  | 	* lpfc_sli_update_ring() don't to read back correct value of | 
					
						
							|  |  |  | 	  cmdidx. | 
					
						
							|  |  |  | 	* Simplified lpfc_sli_resume_iocb() and its use. | 
					
						
							|  |  |  | 	* New static function lpfc_sli_next_iocb(phba, pring, &piocb) to | 
					
						
							|  |  |  | 	  iterate through commands in the TX queue and new command (at the | 
					
						
							|  |  |  | 	  end). | 
					
						
							|  |  |  | 	* Reduced max_lun to 256 (due to issues reported to some arrays). | 
					
						
							|  |  |  | 	  Fixed comment, and macro values so def=256, min=1, max=32768. | 
					
						
							|  |  |  | 	* Fix an obvious typo/bug: kfree was used to free lpfc_scsi_buf | 
					
						
							|  |  |  | 	  instead of mempool_free in lpfc_scsiport.c. | 
					
						
							|  |  |  | 	* Suppress nodev_tmo message for FABRIC nodes. | 
					
						
							|  |  |  | 	* Fixed some usage of plain integer as NULL pointer. | 
					
						
							|  |  |  | 	* Bug fix for FLOGI cmpl, lpfc_els_chk_latt error path code | 
					
						
							|  |  |  | 	  cleanup. | 
					
						
							|  |  |  | 	* Fixup lpfc_els_chk_latt() to have Fabric NPorts go thru | 
					
						
							|  |  |  | 	  discovery state machine as well. | 
					
						
							|  |  |  | 	* Fixes to lpfc_els_chk_latt(). | 
					
						
							|  |  |  | 	* Use DID not SCSI target id as a port_id and add some missing | 
					
						
							|  |  |  | 	  locks in lpfc_fcp.c. | 
					
						
							|  |  |  | 	* Changed eh_abort_handler to return FAILED if command is not | 
					
						
							|  |  |  | 	  found in driver. | 
					
						
							|  |  |  | 	* Fix crash: paging request at virtual address 0000000000100108 - | 
					
						
							|  |  |  | 	  a result of removing from the txcmpl list item which was already | 
					
						
							|  |  |  | 	  removed (100100 is a LIST_POISON1 value from the next pointer | 
					
						
							|  |  |  | 	  and 8 is an offset of the "prev") Driver runs out of iotags and | 
					
						
							|  |  |  | 	  does not handle that case well. The root of the proble is in the | 
					
						
							|  |  |  | 	  initialization code in lpfc_sli.c | 
					
						
							|  |  |  | 	* Changes to work with proposed linux kernel patch to support | 
					
						
							|  |  |  | 	  hotplug. | 
					
						
							|  |  |  | 	* Zero out seg_cnt in prep_io failure path to prevent double sg | 
					
						
							|  |  |  | 	  unmap calls. | 
					
						
							|  |  |  | 	* Fix setting of upper 32 bits for Host Group Ring Pointers if in | 
					
						
							|  |  |  | 	  SLIM. Old code was inappropriately masking off low order bits. | 
					
						
							|  |  |  | 	* Use scsi_[activate|deactivate]_tcq calls provided in scsi_tcq.h. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig (hch@lst.de): don't call | 
					
						
							|  |  |  | 	  pci_dma_sync_* on coherent memory. pci_dma_sync_* is need and | 
					
						
							|  |  |  | 	  must be used only with streaming dma mappings pci_map_*, not | 
					
						
							|  |  |  | 	  coherent mappings.  Note: There are more consistent mappings | 
					
						
							|  |  |  | 	  that are using pci_dma_sync calls. Probably these should be | 
					
						
							|  |  |  | 	  removed as well. | 
					
						
							|  |  |  | 	* Modified lpfc_free_scsi_buf to accomodate all three scsi_buf | 
					
						
							|  |  |  | 	  free types to alleviate miscellaneous panics with cable pull | 
					
						
							|  |  |  | 	  testing. | 
					
						
							|  |  |  | 	* Set hotplug to default 0 and lpfc_target_remove to not remove | 
					
						
							|  |  |  | 	  devices unless hotplug is enabled. | 
					
						
							|  |  |  | 	* Fixed discovery bug: plogi cmpl uses ndlp after its freed. | 
					
						
							|  |  |  | 	* Fixed discovery bug: rnid acc cmpl, can potentially use ndlp | 
					
						
							|  |  |  | 	  after its freed. | 
					
						
							|  |  |  | 	* Modularize code path in lpfc_target_remove(). | 
					
						
							|  |  |  | 	* Changes to support SCSI hotplug (ifdef'ed out because they need | 
					
						
							|  |  |  | 	  kernel support USE_SCAN_TARGET requires kernel support to export | 
					
						
							|  |  |  | 	  the interface to scsi_scan_target and to move the SCAN_WILD_CARD | 
					
						
							|  |  |  | 	  define to a general scsi header file.  USE_RESCAN_HOST requires | 
					
						
							|  |  |  | 	  kernel support to export an interface to scan_scsi_host() with | 
					
						
							|  |  |  | 	  the rescan flag turned on). | 
					
						
							|  |  |  | 	* Removed redundant variable declaration of lpfc_linkdown_tmo. | 
					
						
							|  |  |  | 	* Fix for large port count remove test. | 
					
						
							|  |  |  | 	* Added check to see if BAR1 register is valid before using BAR1 | 
					
						
							|  |  |  | 	  register for programming config_port mail box command. | 
					
						
							|  |  |  | 	* Added lpfc_scsi_hotplug to enable/disable driver support of SCSI | 
					
						
							|  |  |  | 	  hotplug. | 
					
						
							|  |  |  | 	* Changed lpfc_disc_neverdev() to lpfc_disc_illegal() and changed | 
					
						
							|  |  |  | 	  lpfc_disc_nodev() to lpfc_disc_noop().  Adjusted appropriate | 
					
						
							|  |  |  | 	  events to use these routines. | 
					
						
							|  |  |  | 	* Add support for SCSI device hotplug. | 
					
						
							|  |  |  | 	* Take dummy lpfc_target's into account for lpfc_slave_destroy(). | 
					
						
							|  |  |  | 	* Bug fix to store WWPN / WWNN in NameServer / FDMI lpfc_nodelist | 
					
						
							|  |  |  | 	  entries. | 
					
						
							|  |  |  | 	* Added slavecnt in lpfc_target for diagnostic purposes. | 
					
						
							|  |  |  | 	* Added lpfc_hba load/unload flags to take care of special cases | 
					
						
							|  |  |  | 	  for add/remove device. | 
					
						
							|  |  |  | 	* Have target add/remove delay before scanning. | 
					
						
							|  |  |  | 	* Have rmmod path cleanup blocked devices before scsi_remove_host. | 
					
						
							|  |  |  | 	* Added a #define for msleep for 2.6.5 kernels. | 
					
						
							|  |  |  | 	* In reset bus handler if memory allocation fails, return FAILED | 
					
						
							|  |  |  | 	  and not SUCCESS. | 
					
						
							|  |  |  | 	* Have lpfc eh handlers, bus_reset and lun_reset, wait for all | 
					
						
							|  |  |  | 	  associated I/Os to complete before returning. | 
					
						
							|  |  |  | 	* Fix memset byte count in lpfc_hba_init so that | 
					
						
							|  |  |  | 	  LP1050 would initialize correctly. | 
					
						
							|  |  |  | 	* Backround nodev_timeout processing to DPC This enables us to | 
					
						
							|  |  |  | 	  unblock (stop dev_loss_tmo) when appopriate. | 
					
						
							|  |  |  | 	* Fix array discovery with multiple luns.  The max_luns was 0 at | 
					
						
							|  |  |  | 	  the time the host structure was intialized.  lpfc_cfg_params | 
					
						
							|  |  |  | 	  then set the max_luns to the correct value afterwards. | 
					
						
							|  |  |  | 	* Remove unused define LPFC_MAX_LUN and set the default value of | 
					
						
							|  |  |  | 	  lpfc_max_lun parameter to 512. | 
					
						
							|  |  |  | 	* Reduced stack usage of lpfc_hba_init. | 
					
						
							|  |  |  | 	* Cleaned up the following warning generated by | 
					
						
							|  |  |  | 	  scripts/checkincludes.pl lpfc_fcp.c: scsi/scsi_cmnd.h is | 
					
						
							|  |  |  | 	  included more than once. | 
					
						
							|  |  |  | 	* Replaced "set_current_state(TASK_UNINTERRUPTIBLE); | 
					
						
							|  |  |  | 	  schedule_timeout(timeout)" with "msleep(timeout)". | 
					
						
							|  |  |  | 	* Fixnode was loosing starget when rediscovered. We saw messages | 
					
						
							|  |  |  | 	  like: lpfc 0000:04:02.0: 0:0263 Cannot block scsi target as a | 
					
						
							|  |  |  | 	  result.  Moved starget field into struct lpfc_target which is | 
					
						
							|  |  |  | 	  referenced from the node. | 
					
						
							|  |  |  | 	* Add additional SLI layer logging in lpfc_sli.c. | 
					
						
							|  |  |  | 	* Ignore more unexpected completions in lpfc_nportdisc.c. | 
					
						
							|  |  |  | 	* Can not call lpfc_target_unblock from the soft interrupt | 
					
						
							|  |  |  | 	  context.  It seems to be not nessasery to unblock target from | 
					
						
							|  |  |  | 	  nodev timeout. | 
					
						
							|  |  |  | 	* Introduce and use less lethal event handler for unexpected | 
					
						
							|  |  |  | 	  events in lpfc_nportdisc.c. | 
					
						
							|  |  |  | 	* Can not call fc_target_(un)block() functions with interrupts | 
					
						
							|  |  |  | 	  disabled in lpfc_scsiport.c. | 
					
						
							|  |  |  | 	* Added new configuration parameter, lpfc_max_luns range 1-32768, | 
					
						
							|  |  |  | 	  default 32768. | 
					
						
							|  |  |  | 	* Allow lpfc_fcp.c to call lpfc_get_hba_sym_node_name(). | 
					
						
							|  |  |  | 	* Increase nodev timeout from 20 seconds to 30 seconds. | 
					
						
							|  |  |  | 	* Replace some kfree((void*)ptr) with kfree(ptr). | 
					
						
							|  |  |  | 	* Make 3 functions static: lpfc_get_hba_sym_node_name, | 
					
						
							|  |  |  | 	  lpfc_intr_prep and lpfc_setup_slim_access.  Move lpfc_intr_prep | 
					
						
							|  |  |  | 	  and lpfc_setup_slim_access so they're defined before being used. | 
					
						
							|  |  |  | 	* Remove an unecessary list_del() in lpfc_hbadisc.c. | 
					
						
							|  |  |  | 	* Set nlp_state before calling lpfc_nlp_list() since this will | 
					
						
							|  |  |  | 	  potentially call fc_target_unblock which may cause a race in | 
					
						
							|  |  |  | 	  queuecommand by releasing host_lock. | 
					
						
							|  |  |  | 	* Since lpfc_nodev_tmo < dev_loss_tmo remove queuecommand | 
					
						
							|  |  |  | 	  DID_BAD_TARGET return for now. | 
					
						
							|  |  |  | 	* Fix a problem with rcv logo. | 
					
						
							|  |  |  | 	* Remove unused portstatistics_t structure. | 
					
						
							|  |  |  | 	* Remove #if 0 and unnecessary checks in lpfc_fcp.c. | 
					
						
							|  |  |  | 	* Simplify lpfc_issue_lip: Extra layer of protection removed. | 
					
						
							|  |  |  | 	* Grab lock before calling lpfc_sli_issue_mbox(phba, pmb, | 
					
						
							|  |  |  | 	  MBX_NOWAIT) in lpfc_sli_issue_mbox_wait(). | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040920 to 20041018 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.13 | 
					
						
							|  |  |  | 	* Hide some attributes using #ifndef DFC_DEBUG ... #endif. | 
					
						
							|  |  |  | 	* Modify Makefile to (1) make BUILD_NO_DEBUG=1 will hide some | 
					
						
							|  |  |  | 	  (binary) attributes (2) make BUILD_FC_TRANS=0 will build driver | 
					
						
							|  |  |  | 	  for 2.6.5 kernel with block/unblock patch. | 
					
						
							|  |  |  | 	* Modified #ifdef names. | 
					
						
							|  |  |  | 	* Added support for proposed FC transport host attributes (which | 
					
						
							|  |  |  | 	  replaces some of the attributes we had local to the driver). | 
					
						
							|  |  |  | 	  Removed the binary statistics sysfs attribute. | 
					
						
							|  |  |  | 	* Added extra ELS verbose logging for ELS responses. | 
					
						
							|  |  |  | 	* Added recognition for BUILD_FC_TRANS=2 to Makefile to define | 
					
						
							|  |  |  | 	  FC_TRANS_VER2. | 
					
						
							|  |  |  | 	* Add a pointer for link stats allocation. | 
					
						
							|  |  |  | 	* Exported lpfc_get_hba_sym_node_name for use by FC_TRANS_VER2 | 
					
						
							|  |  |  | 	  sysfs routines. | 
					
						
							|  |  |  | 	* Fix discovery problem in lip testing: if device sends an ELS cmd | 
					
						
							|  |  |  | 	  (i.e. LOGO) before our FLOGI completes it should be LS_RJT'ed. | 
					
						
							|  |  |  | 	* Moved #defines around to provide target_add/remove for upstream | 
					
						
							|  |  |  | 	  kernel deliverables only not SLES9.  Provided ifdefs to #include | 
					
						
							|  |  |  | 	  target_block/unblock only if FC_TRANS_VER1. | 
					
						
							|  |  |  | 	* Add sanity check in lpfc_nlp_list move setting nlp_Target | 
					
						
							|  |  |  | 	  outside #ifdef. | 
					
						
							|  |  |  | 	* Added a blocked member to the lpfc_target structure for | 
					
						
							|  |  |  | 	  block/unblock.  This member allows the driver to know when to | 
					
						
							|  |  |  | 	  unblock for pci_remove_one or pci_add_one.  #ifdef'd some more | 
					
						
							|  |  |  | 	  block/unblock stuff and removed some defensive checks from | 
					
						
							|  |  |  | 	  target_block/unblock. | 
					
						
							|  |  |  | 	* Moved + 5 second window to dev_loss_tmo setting and updated | 
					
						
							|  |  |  | 	  comments. | 
					
						
							|  |  |  | 	* Removed NULL target check from target_block/unblock and fixed up | 
					
						
							|  |  |  | 	  a few comments. | 
					
						
							|  |  |  | 	* Enable sysfs attributes on 2.6.5 kernels and remove extra | 
					
						
							|  |  |  | 	  compatibility code. | 
					
						
							|  |  |  | 	* Remove any and all trailing whitespace. | 
					
						
							|  |  |  | 	* Added message 0718 and return error when dma_map_single fails. | 
					
						
							|  |  |  | 	* Changed the fcpCntl2 commands to include an FCP_ prefix to get | 
					
						
							|  |  |  | 	  rid of build warnings on later 2.6.9-rc kernels.  Build | 
					
						
							|  |  |  | 	  conflicts with scsi/scsi.h.  Remove inclusions of scsi/scsi.h | 
					
						
							|  |  |  | 	  from hbadisc.c, sli.c, and fcp.c since these modules had no | 
					
						
							|  |  |  | 	  dependencies on scsi.h. | 
					
						
							|  |  |  | 	* Fixed a bug with RSCN handling. A RSCN received on one device, | 
					
						
							|  |  |  | 	  shouldn't affect other devices not referenced by the RSCN. | 
					
						
							|  |  |  | 	* Moved #if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,6) to include | 
					
						
							|  |  |  | 	  lpfc_jedec_to_ascii to prevent warning in SLES 9. | 
					
						
							|  |  |  | 	* Update Makefile to account for SLES 9 and scsi-target upstream | 
					
						
							|  |  |  | 	  kernel. | 
					
						
							|  |  |  | 	* This checkin provides block/unblock hooks for the upstream scsi | 
					
						
							|  |  |  | 	  target kernel and 2.6.5 on SLES9 SP1 with the block/unblock | 
					
						
							|  |  |  | 	  patch. | 
					
						
							|  |  |  | 	* Discovery changes regarding setting targetp->pnode and | 
					
						
							|  |  |  | 	  ndlp->nlp_Target Ensure fc_target_* routines are called properly | 
					
						
							|  |  |  | 	  from discovery.  Remove list_del's from lpfc_cleanup().  Ensure | 
					
						
							|  |  |  | 	  all the lpfc_consistent_bind_* routines don't set any driver | 
					
						
							|  |  |  | 	  structure objects. | 
					
						
							|  |  |  | 	* Fix for timeout of READ_LA or READ_SPARAM mailbox command | 
					
						
							|  |  |  | 	  causing panic. | 
					
						
							|  |  |  | 	* Cleanup list_del()'s for Discovery ndlp lists. | 
					
						
							|  |  |  | 	* Bug fixes for some insmod/rmmod crashes, link down crashes and | 
					
						
							|  |  |  | 	  device loss crashes. | 
					
						
							|  |  |  | 	* Removed NLP_SEARCH_DEQUE. | 
					
						
							|  |  |  | 	* Call lpfc_target_unblock only if the targetp is nonNull and with | 
					
						
							|  |  |  | 	  the host_lock held. | 
					
						
							|  |  |  | 	* Added qcmdcnt back along with misc bug fixes to discovery. | 
					
						
							|  |  |  | 	* Changed tgt_io to outfcpio lpfc_fcp.c. | 
					
						
							|  |  |  | 	* Fixed errors caused by LIP and cable pulls both with and without | 
					
						
							|  |  |  | 	  block/unblock patch. | 
					
						
							|  |  |  | 	* For now we have to call fc_target_unblock and fc_target_block | 
					
						
							|  |  |  | 	  with interrupts enabled. | 
					
						
							|  |  |  | 	* Save seg_cnt from dma_map_sg.  Save scatter-gather start address | 
					
						
							|  |  |  | 	  and pass back to dma_unmap_sg in error with seg_cnt. | 
					
						
							|  |  |  | 	* Incorporating block/unblock calls into driver with ifdefs.  This | 
					
						
							|  |  |  | 	  change is supported by scsi-target-2.6 kernel and forward only. | 
					
						
							|  |  |  | 	* Merged in some discovery bug fixes and added tgt io counters. | 
					
						
							|  |  |  | 	* Added sysfs attributes/interfaces: read only attribute | 
					
						
							|  |  |  | 	  "management_version" and write only attribute "issue_lip". | 
					
						
							|  |  |  | 	* Fix build on big endian machines: while #if was OK with | 
					
						
							|  |  |  | 	  __BIG_ENDIAN which defined as 4321, __BIG_ENDIAN_BITFIELD has to | 
					
						
							|  |  |  | 	  be tested with #ifdef because it does not have any value, it is | 
					
						
							|  |  |  | 	  either defined or not. | 
					
						
							|  |  |  | 	* Add fabric_name and port_type attributes. | 
					
						
							|  |  |  | 	* Change mdelay to msleep.  mdelay works, but wastefully uses cpu | 
					
						
							|  |  |  | 	  resources without a lock held. Revert to msleep.  Tested with | 
					
						
							|  |  |  | 	  sg_reset for bus and three attached targets. | 
					
						
							|  |  |  | 	* Added the customary #ifndef...#define...#endif to | 
					
						
							|  |  |  | 	  lpfc_version.h. | 
					
						
							|  |  |  | 	* Integrate patches from Christoph Hellwig: two new helpers common | 
					
						
							|  |  |  | 	  to lpfc_sli_resume_iocb and lpfc_sli_issue_iocb - singificant | 
					
						
							|  |  |  | 	  cleanup of those two functions - the unused SLI_IOCB_USE_TXQ is | 
					
						
							|  |  |  | 	  gone - lpfc_sli_issue_iocb_wait loses it's flags argument | 
					
						
							|  |  |  | 	  totally. | 
					
						
							|  |  |  | 	* Fix in lpfc_sli.c: we can not store a 5 bit value in a 4-bit | 
					
						
							|  |  |  | 	  field. | 
					
						
							|  |  |  | 	* Moved some routines out of lpfc_fcp.c into more appropriate | 
					
						
							|  |  |  | 	  files. | 
					
						
							|  |  |  | 	* Whitespace cleanup: remove all trailing whitespace. | 
					
						
							|  |  |  | 	* Make lpfc_disc_ndlp_show static to lpfc_fcp.c. | 
					
						
							|  |  |  | 	* Remove leftover printk and replace some with | 
					
						
							|  |  |  | 	  printk(KERN_WARNING) | 
					
						
							|  |  |  | 	* Trivial: fix a few long lines and a soft tab. | 
					
						
							|  |  |  | 	* Remove warnings generated by Sparse against driver (make | 
					
						
							|  |  |  | 	  C=1). Mostly these are "using integer as pointer warnings" | 
					
						
							|  |  |  | 	  i.e. use NULL instead of 0. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig: Quite a lot of changes | 
					
						
							|  |  |  | 	  here, the most notable is that the phba->slim2p lpfc_dmabuf goes | 
					
						
							|  |  |  | 	  away in favour of a typede pointer and a dma_addr_t.  Due to the | 
					
						
							|  |  |  | 	  typed pointer lots of the cast mess can go away, and while at it | 
					
						
							|  |  |  | 	  I also replaced the messy SLI2_SLIM_t with a simple struct | 
					
						
							|  |  |  | 	  lpfc2_sli2_slim that only contains the part of the union we care | 
					
						
							|  |  |  | 	  about while using SLI2_SLIM_SIZE for all size calculations | 
					
						
							|  |  |  | 	  directly. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig: This streamlines the | 
					
						
							|  |  |  | 	  I/O completion path a little more, especially taking care of | 
					
						
							|  |  |  | 	  fast-pathing the non-error case.  Also removes tons of dead | 
					
						
							|  |  |  | 	  members and defines from lpfc_scsi.h - e.g. lpfc_target is down | 
					
						
							| 
									
										
										
										
											2008-10-16 19:02:37 +02:00
										 |  |  | 	  to nothing more than the lpfc_nodelist pointer. | 
					
						
							| 
									
										
										
										
											2005-04-17 16:05:31 -05:00
										 |  |  | 	* Added binary sysfs file to issue mbox commands | 
					
						
							|  |  |  | 	* Replaced #if __BIG_ENDIAN with #if __BIG_ENDIAN_BITFIELD for | 
					
						
							|  |  |  | 	  compatibility with the user space applications. | 
					
						
							|  |  |  | 	* Decrease the amount of data in proc_info. | 
					
						
							|  |  |  | 	* Condense nodelist flag members. | 
					
						
							|  |  |  | 	* Expand INFO for discovery sysfs shost entries. | 
					
						
							|  |  |  | 	* Notify user if information exceeds 4k sysfs limit. | 
					
						
							|  |  |  | 	* Removed a bunch of unused #defines. | 
					
						
							|  |  |  | 	* Added initial sysfs discovery shost attributes. | 
					
						
							|  |  |  | 	* Remove unused #defines lpfc_disc.h. | 
					
						
							|  |  |  | 	* Fixed failMask nodelist settings. | 
					
						
							|  |  |  | 	* Cleanup some old comments / unused variables. | 
					
						
							|  |  |  | 	* Add LP101 to list of recognized adapters. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040908 to 20040920 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.12 | 
					
						
							|  |  |  | 	* Removed used #defines: DEFAULT_PCI_LATENCY_CLOCKS and | 
					
						
							|  |  |  | 	  PCI_LATENCY_VALUE from lpfc_hw.h. | 
					
						
							|  |  |  | 	* Changes to accomodate rnid. | 
					
						
							|  |  |  | 	* Fix RSCN handling so RSCN NS queries only effect NPorts found in | 
					
						
							|  |  |  | 	  RSCN data. | 
					
						
							|  |  |  | 	* If we rcv a plogi on a NPort queued up for discovery, clear the | 
					
						
							|  |  |  | 	  NLP_NPR_2B_DISC bit since rcv plogi logic will force NPort thru | 
					
						
							|  |  |  | 	  discovery. | 
					
						
							|  |  |  | 	* Ensure lpfc_target is also cleaned up in lpfc_cleanup(). | 
					
						
							|  |  |  | 	* Preliminary changes for block/unblock kernel API extensions in | 
					
						
							|  |  |  | 	  progress with linux-scsi list.  These are name changes and | 
					
						
							|  |  |  | 	  prototype changes only. | 
					
						
							|  |  |  | 	* Added send_abts flag to lpfc_els_abort. For rcv LOGO when ADISC | 
					
						
							|  |  |  | 	  sent, the XRI of the LOGO rcv'ed is the same as the ADISC | 
					
						
							|  |  |  | 	  sent. Thus we cannot ABTS the ADISC before sending the LOGO ACC. | 
					
						
							|  |  |  | 	* Weed out some unused fc_flags.  Add FC_DISC_TMO. | 
					
						
							|  |  |  | 	* board_online sysfs attribute added to support libdfc functions | 
					
						
							|  |  |  | 	  InitDiagEnv and SetBrdEnv. | 
					
						
							|  |  |  | 	* Streamline code in lpfc_els_retry fixup abort case in | 
					
						
							|  |  |  | 	  lpfc_els_timeout_handler(). | 
					
						
							|  |  |  | 	* Flush discovery/ELS events when we bring SLI layer down. | 
					
						
							|  |  |  | 	* ctlreg and slimem binary attributes added to support libdfc | 
					
						
							|  |  |  | 	  read/write mem/ctl functions. | 
					
						
							|  |  |  | 	* Integrated Christoph Hellwig's patch: Cleanup | 
					
						
							|  |  |  | 	  lpfc_sli_ringpostbuf_get. | 
					
						
							|  |  |  | 	* Modified lpfc_slave_alloc and lpfc_slave_destroy to allocate and | 
					
						
							|  |  |  | 	  free a dummy target pointer.  This allows queuecommand to skip | 
					
						
							|  |  |  | 	  the NULL target pointer check and avoid the console spam when | 
					
						
							|  |  |  | 	  slave_alloc fails. | 
					
						
							|  |  |  | 	* Fix cfg_scan_down logic, it was reversed. | 
					
						
							|  |  |  | 	* Init list head ctrspbuflist. | 
					
						
							|  |  |  | 	* Change name of lpfc_driver_abort to lpfc_els_abort since it is | 
					
						
							|  |  |  | 	  only valid for ELS ring. | 
					
						
							|  |  |  | 	* Remove unused third argument for lpfc_consistent_bind_get(). | 
					
						
							|  |  |  | 	* Fix up iotag fields in lpfc_prep_els_iocb(). | 
					
						
							|  |  |  | 	* Remove log message on code path triggered by lpfc_els_abort(). | 
					
						
							|  |  |  | 	* Set host->unique_id in lpfc_fcp.c. | 
					
						
							|  |  |  | 	* Removed deadwood: lpfc_target.pHba not necessary anymore. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig: remove dead | 
					
						
							|  |  |  | 	  SLI_IOCB_POLL handling. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig: Streamline I/O | 
					
						
							|  |  |  | 	  submission and completion path a little. | 
					
						
							|  |  |  | 	* Remove unnecessary lpfc_brd_no.  Ensure brd_no assignment is | 
					
						
							|  |  |  | 	  unique. | 
					
						
							|  |  |  | 	* Removed unused MAX_FCP_LUN. | 
					
						
							|  |  |  | 	* Use mod_timer instead of add_timer for fdmi in lpfc_ct.c. | 
					
						
							|  |  |  | 	* Fixed misc discovery problems. | 
					
						
							|  |  |  | 	* Move stopping timers till just before lpfc_mem_free() call. | 
					
						
							|  |  |  | 	* Fix up NameServer reglogin error path. | 
					
						
							|  |  |  | 	* Cleanup possible outstanding discovery timers on rmmod. | 
					
						
							|  |  |  | 	* Fix discovery NPort to NPort pt2pt problem. | 
					
						
							|  |  |  | 	* Get rid of ip_tmofunc / scsi_tmofunc. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig: | 
					
						
							|  |  |  | 	  lpfc_disc_done/lpfc_do_dpc cleanup - lpfc_disc_done can return | 
					
						
							|  |  |  | 	  void - move lpfc_do_dpc and lpfc_disc_done to lpfc_hbadisc.c - | 
					
						
							|  |  |  | 	  remove checking of list emptiness before calling lpfc_disc_done, | 
					
						
							|  |  |  | 	  it handles the emtpy list case just fine and the additional | 
					
						
							|  |  |  | 	  instructions cost less then the bustlocked spinlock operations. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig: This adds a new 64bit | 
					
						
							|  |  |  | 	  counter instead, brd_no isn't reused anymore.  Also some tiny | 
					
						
							|  |  |  | 	  whitespace cleanups in surrounding code. | 
					
						
							|  |  |  | 	* Reorder functions in lpfc_els.c to remove need for prototypes. | 
					
						
							|  |  |  | 	* Removed unsed prototypes from lpfc_crtn.h - | 
					
						
							|  |  |  | 	  lpfc_ip_timeout_handler, lpfc_read_pci and lpfc_revoke. | 
					
						
							|  |  |  | 	* Removed some unused prototypes from lpfc_crtn.h - | 
					
						
							|  |  |  | 	  lpfc_scsi_hba_reset, lpfc_scsi_issue_inqsn, | 
					
						
							|  |  |  | 	  lpfc_scsi_issue_inqp0, lpfc_scsi_timeout_handler. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig: remove TRUE/FALSE | 
					
						
							|  |  |  | 	  usage. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig: Remove unused function | 
					
						
							|  |  |  | 	  prototypes lpfc_set_pkt_len and lpfc_get_pkt_data from | 
					
						
							|  |  |  | 	  lpfc_crtn.h - fixes build warnings. | 
					
						
							|  |  |  | 	* Removed unused struct lpfc_dmabufip definition from lpfc_mem.h. | 
					
						
							|  |  |  | 	* Removed pre-2.6.5 MODULE_VERSION macro from lpfc_compat.h. | 
					
						
							|  |  |  | 	* Fixing missing static and removing dead code. | 
					
						
							|  |  |  | 	* Adding nodewwn, portwwn and portfcid shost attributes. | 
					
						
							|  |  |  | 	* Initial support for CT via sysfs. request payloads of size less | 
					
						
							|  |  |  | 	  than PAGE_SIZE and rsp payloads of size PAGE_SIZE are supported. | 
					
						
							|  |  |  | 	  Driver maintains a list of rsp's and passes back rsp's | 
					
						
							|  |  |  | 	  corresponding to the pid of the calling process. | 
					
						
							|  |  |  | 	* Support for RefreshInformation, GetAdapterAttributes, | 
					
						
							|  |  |  | 	  GetPortStatistics. | 
					
						
							|  |  |  | 	* Make nodev-tmo default to 20 seconds. | 
					
						
							|  |  |  | 	* Fix up some DSM error cases, unreg_login rpi where needed. | 
					
						
							|  |  |  | 	* Fix up comments for fc_target_block / fc_target_unblock. | 
					
						
							|  |  |  | 	* Fix up code for scsi_block_requests / scsi_unblock_requests. | 
					
						
							|  |  |  | 	* Add NLP_FCP_TARGET for nodeinfo support. | 
					
						
							|  |  |  | 	* Move suspend/resume in lpfc_nlp_list under appropriate case - | 
					
						
							|  |  |  | 	  Used host_lock for DPC to avoid race (remove dpc_lock) | 
					
						
							|  |  |  | 	* Fix some corner cases for PLOGI receive - simplify error case | 
					
						
							|  |  |  | 	  for cmpl_reglogin_reglogin_issue. | 
					
						
							|  |  |  | 	* Bug fix for ppc64 EEH MMIO panic - always do readl after | 
					
						
							|  |  |  | 	  writel's of HBA registers to force flush. | 
					
						
							|  |  |  | 	* Get rid of initial static routine declarations in lpfc_hbadisc.c | 
					
						
							|  |  |  | 	  and lpfc_els.c. | 
					
						
							|  |  |  | 	* Updates to discovery processing. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040823 to 20040908 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.11 | 
					
						
							|  |  |  | 	* Removed persistent binding code. | 
					
						
							|  |  |  | 	* Display both ASC and ASCQ info. | 
					
						
							|  |  |  | 	* Fixed link down->up transitions when linkdown tmo expires. Fix | 
					
						
							|  |  |  | 	  was in the defensive error checking at the start of | 
					
						
							|  |  |  | 	  queuecommand. | 
					
						
							|  |  |  | 	* Removed lpfc_scsi_timeout_handler as this timer is no longer | 
					
						
							|  |  |  | 	  required.  The midlayer will exhaust retries and then call | 
					
						
							|  |  |  | 	  lpfc_abort_handler, lpfc_reset_lun_handler, and | 
					
						
							|  |  |  | 	  lpfc_reset_target_handler. | 
					
						
							|  |  |  | 	* Minimal support for SCSI flat space addressing/volume set | 
					
						
							|  |  |  | 	  addressing.  Use 16 bits of LUN address so that flat | 
					
						
							|  |  |  | 	  addressing/VSA will work. | 
					
						
							|  |  |  | 	* Changed 2 occurences of if( 1 != f(x)) to if(f(x) != 1) | 
					
						
							|  |  |  | 	* Drop include of lpfc_cfgparm.h. | 
					
						
							|  |  |  | 	* Reduce stack usage of lpfc_fdmi_cmd in lpfc_ct.c. | 
					
						
							|  |  |  | 	* Add minimum range checking property to /sys write/store | 
					
						
							|  |  |  | 	  functions. | 
					
						
							|  |  |  | 	* Fix display of node_name and port_name via fc transport | 
					
						
							|  |  |  | 	  attr. | 
					
						
							|  |  |  | 	* Removed biosparam code. | 
					
						
							|  |  |  | 	* Removed range checking. phba->config[] array elements are now | 
					
						
							|  |  |  | 	  embedded into the hba struct. lpfc_config_setup() has been | 
					
						
							|  |  |  | 	  removed. | 
					
						
							|  |  |  | 	* Collapsed lpfc_scsi_cmd_start into lpfc_queuecommand and cleaned | 
					
						
							|  |  |  | 	  up combined routines. | 
					
						
							|  |  |  | 	* Removed unused prototypes myprint and | 
					
						
							|  |  |  | 	  lpfc_sched_service_high_priority_queue. | 
					
						
							|  |  |  | 	* Removed unused function lpfc_nodev. | 
					
						
							|  |  |  | 	* Removed scsi_cmnd->timeout_per_command cancelation. SCSI midlayer | 
					
						
							|  |  |  | 	  now times out all commands - FW is instructed to not timeout. | 
					
						
							|  |  |  | 	* Removed polling code from lpfc_scsi_cmd_start. Reorganized | 
					
						
							|  |  |  | 	  queuecommand and cmd_start some. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040810 to 20040823 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.10 | 
					
						
							|  |  |  | 	* Additional timer changes as per Arjan / Christoph's comments. | 
					
						
							|  |  |  | 	* Used mod_timer() instead of del_timer_sync() where appropriate. | 
					
						
							|  |  |  | 	* Fixed a use after free case (panic on 2.6.8.1 with | 
					
						
							|  |  |  | 	  CONFIG_DEBUG_SLAB set). | 
					
						
							|  |  |  | 	* Fix compile warning in lpfc_fcp.c. | 
					
						
							|  |  |  | 	* Minor fix for log message, that prints unassigned brdno which is | 
					
						
							|  |  |  | 	  zero. | 
					
						
							|  |  |  | 	* Move scsi_host_alloc() to the beginning of probe_one(). This | 
					
						
							|  |  |  | 	  ensures that host_lock is available at later stages and also | 
					
						
							|  |  |  | 	  avoids tons of unnecessary initializing if host_alloc() | 
					
						
							|  |  |  | 	  fails. | 
					
						
							|  |  |  | 	* Removed else clause from lpfc_slave_configure that set | 
					
						
							|  |  |  | 	  sdev->queue_depth.  The driver informs the midlayer of its | 
					
						
							|  |  |  | 	  setting in the template and only overrides if queue tagging is | 
					
						
							|  |  |  | 	  enabled. | 
					
						
							|  |  |  | 	* Added PCI_DEVICE_ID_ZEPHYR and PCI_DEVICE_ID_ZFLY (Junior | 
					
						
							|  |  |  | 	  Zephyr) support | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040730 to 20040810 | 
					
						
							|  |  |  | 	 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.9 | 
					
						
							|  |  |  | 	* Removed per HBA driver lock.  Driver now uses the host->host_lock | 
					
						
							|  |  |  | 	* Restored support for the 2.6.5 kernel for those linux distributions | 
					
						
							|  |  |  | 	  shipped with the 2.6.5 kernel. | 
					
						
							|  |  |  | 	* Applied patch from Christoph Hellwig (hch@infradead.org) as follows | 
					
						
							|  |  |  | 	  "[PATCH] use scsi host private data in ->proc_info.   | 
					
						
							|  |  |  | 	* Applied patch from Christoph Hellwig (hch@infradead.org) as follows | 
					
						
							|  |  |  | 	  "Re: [Emulex] Ready for next round.  This patch cleans up the memory  | 
					
						
							|  |  |  | 	  allocation routines a little and fixes a missing mempool_destroy and | 
					
						
							|  |  |  | 	  some missing error handling." | 
					
						
							|  |  |  | 	* Changed pointers assignments from 0 to NULL. | 
					
						
							|  |  |  | 	* Added fixes to the lpfc_reset_lun_handler and lpfc_reset_bus_handler | 
					
						
							|  |  |  | 	  entry points that caused kernel to Oops or hang. | 
					
						
							|  |  |  | 	* Added fixes to targetless hosts that caused modprobe and insmod to hang. | 
					
						
							|  |  |  | 	* Ongoing cleanup to many files | 
					
						
							|  |  |  | 	   | 
					
						
							|  |  |  | Changes from 20040723 to 20040730 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.8 | 
					
						
							|  |  |  | 	* Removed unused LPFN_DRIVER_VERSION #define. | 
					
						
							|  |  |  | 	* Folded lpfc_findnode_scsiid into lpfc_find_target, its only | 
					
						
							|  |  |  | 	  caller. | 
					
						
							|  |  |  | 	* Removed 2 unneeded arguments to lpfc_find_target (lun and | 
					
						
							|  |  |  | 	  create_flag). | 
					
						
							|  |  |  | 	* Make lpfc_sli_reset_on_init = 1 | 
					
						
							|  |  |  | 	* Minor cleanup to quieten sparse. | 
					
						
							|  |  |  | 	* Removed missing function = 0 in tmo routine in lpfc_els.c. | 
					
						
							|  |  |  | 	* Moved additional binding parameters into lpfc_defaults.c: | 
					
						
							|  |  |  | 	  lpfc_automap / lpfc_fcp_bind_method | 
					
						
							|  |  |  | 	* Use msecs_to_jiffies() where applicable. | 
					
						
							|  |  |  | 	* Only use queue depth attribute only after SLI HBA setup was | 
					
						
							|  |  |  | 	  completed. | 
					
						
							|  |  |  | 	* Put in memory barriers for PPC | 
					
						
							|  |  |  | 	* Added PCI_DEVICE_ID_HELIOS and PCI_DEVICE_ID_JFLY (Junior | 
					
						
							|  |  |  | 	  Helios) support | 
					
						
							|  |  |  | 	* Added 4&10 gigabit choices in user option link_speed | 
					
						
							|  |  |  | 	* Updated timer logic: Set timer data after init_timer use | 
					
						
							|  |  |  | 	  timer_pending() instead of expires. | 
					
						
							|  |  |  | 	* Removed some remnants of IP over FC support from Kconfig and | 
					
						
							|  |  |  | 	  Makefile. | 
					
						
							|  |  |  | 	* Remove redundant prototypes for lpfc_handle_eratt, | 
					
						
							|  |  |  | 	  lpfc_handle_latt and lpfc_read_pci. | 
					
						
							|  |  |  | 	* Ongoing cleanup of lpfc_init.c. | 
					
						
							|  |  |  | 	* Changed LPFC_CFG_DFT_HBA_Q_DEPTH -> LPFC_CFG_HBA_Q_DEPTH. | 
					
						
							|  |  |  | 	* Another cleanup stab at lpfc_ct.c. Remove castings, structure | 
					
						
							|  |  |  | 	  code sanely, remove redundant code, reorganize code so that | 
					
						
							|  |  |  | 	  functions are invoked after definition. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040716 to 20040723 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.7 | 
					
						
							|  |  |  | 	* Cleanup of lpfc_ct.c. Removed number of casts, removed tons of | 
					
						
							|  |  |  | 	  dead/redundant code, cleaned up badly and poorly written code, | 
					
						
							|  |  |  | 	  cleaned up return values. | 
					
						
							|  |  |  | 	* Fixed Persistent binding implementation | 
					
						
							|  |  |  | 	* Removed all references to lpfc_scsi_req_tmo | 
					
						
							|  |  |  | 	* Removed last references to lun_skip config parameter. | 
					
						
							|  |  |  | 	* Removed LPFC_DEV_RPTLUN node failure bit because we don't issue | 
					
						
							|  |  |  | 	  REPORT_LUNS from the driver anymore. | 
					
						
							|  |  |  | 	* Removed LUN-tracking in driver.  Removed lpfc_lun struct and | 
					
						
							|  |  |  | 	  moved any functionality we still need to lpfc_target. | 
					
						
							|  |  |  | 	* Added new lpfc_jedec_to_ascii() call and replace two instances | 
					
						
							|  |  |  | 	  of duplicate code with calls to this function. | 
					
						
							|  |  |  | 	* Removed Volume Set Addressing handling on LUN IDs. | 
					
						
							|  |  |  | 	* Applied patch from Christoph Hellwig (hch@infradead.org) that | 
					
						
							|  |  |  | 	  removes dead code belonging to lpfc_build_scsi_cmnd() and its | 
					
						
							|  |  |  | 	  call path. This is related to the recently removed report_lun | 
					
						
							|  |  |  | 	  code. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040709 to 20040716 |

							|  |  |  | 	  lpfc_disc_retry_rptlun and their use. | 
					
						
							|  |  |  | 	* Removed usused scheduler prototypes in lpfc_crtn.h | 
					
						
							|  |  |  | 	* Replace lpfc_geportname() with generic memcmp(). | 
					
						
							|  |  |  | 	* Rearrange code in lpfc_rcv_plogi_plogi_issue() to make it a | 
					
						
							|  |  |  | 	  little more readable. | 
					
						
							|  |  |  | 	* Remove redundant port_cmp != 2 check in if | 
					
						
							|  |  |  | 	  (!port_cmp) { .... if (port_cmp != 2).... } | 
					
						
							|  |  |  | 	* Clock changes: removed struct clk_data and timerList. | 
					
						
							|  |  |  | 	* Clock changes: seperate nodev_tmo and els_retry_delay into 2 | 
					
						
							|  |  |  | 	  seperate timers and convert to 1 argument changed | 
					
						
							|  |  |  | 	  LPFC_NODE_FARP_PEND_t to struct lpfc_node_farp_pend convert | 
					
						
							|  |  |  | 	  ipfarp_tmo to 1 argument convert target struct tmofunc and | 
					
						
							|  |  |  | 	  rtplunfunc to 1 argument * cr_count, cr_delay and | 
					
						
							|  |  |  | 	  discovery_threads are only needed to be module_params and not | 
					
						
							|  |  |  | 	  visible via sysfs. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040614 to 20040709 |

							|  |  |  | 	* Changed ULP_BDE to struct ulp_bde. | 
					
						
							|  |  |  | 	* Cleanup lpfc_os_return_scsi_cmd() and it's call path. | 
					
						
							|  |  |  | 	* Removed lpfc_no_device_delay. | 
					
						
							|  |  |  | 	* Consolidating lpfc_hba_put_event() into lpfc_put_event(). | 
					
						
							|  |  |  | 	* Removed following attributes and their functionality: | 
					
						
							|  |  |  | 	  lpfc_extra_io_tmo, lpfc_nodev_holdio, lpfc_delay_rsp_err, | 
					
						
							|  |  |  | 	  lpfc_tgt_queue_depth and lpfc_check_cond_err. | 
					
						
							|  |  |  | 	* Clock changes consolidating timers, just in the struct lpfc_hba, | 
					
						
							|  |  |  | 	  to get rid of clkData and pass only one argument to timeout | 
					
						
							|  |  |  | 	  routine. Also, removing need for outstanding clock linked list | 
					
						
							|  |  |  | 	  to stop these timers at rmmod. | 
					
						
							|  |  |  | 	* Move lpfc.conf contents into lpfc_fcp.c. Removing per adapter | 
					
						
							|  |  |  | 	  attributes in favor of global attributes. | 
					
						
							|  |  |  | 	* Fix a potential null pointer reference of pmbuf in lpfc_ct.c. | 
					
						
							|  |  |  | 	* On reset_lun, issue LUN_RESET as opposed to ABORT_TASK_SET. | 
					
						
							|  |  |  | 	* Removed SCSI_REQ_TMO related code. | 
					
						
							|  |  |  | 	* Introducing two new defines LPFC_ATTR_R and LPFC_ATTR_RW that do | 
					
						
							|  |  |  | 	  a module_param, MODULE_PARM_DESC, lpfc_param_show, | 
					
						
							|  |  |  | 	  [lpfc_param_store] and CLASS_DEVICE_ATTRIBUTE. | 
					
						
							|  |  |  | 	* Properly clean up when allocation of a linked BDE fails in the | 
					
						
							|  |  |  | 	  SCSI queuecommand path. | 
					
						
							|  |  |  | 	* Fail SCSI command if dma_map_sg call fails. | 
					
						
							|  |  |  | 	* Remove unused macros SWAP_ALWAYS and SWAP_ALWAYS16. | 
					
						
							|  |  |  | 	* Reset context2 to 0 on exit in | 
					
						
							|  |  |  | 	  lpfc_sli_issue_iocb_wait_high_priority() and | 
					
						
							|  |  |  | 	  lpfc_sli_issue_iocb_wait(). | 
					
						
							|  |  |  | 	* Arranging lpfc_scsiport.c to follow style of use after | 
					
						
							|  |  |  | 	  definition. This removes the need for the cruft of forward | 
					
						
							|  |  |  | 	  declarations. Also removing a redundant #define ScsiResult as it | 
					
						
							|  |  |  | 	  already available elsewhere. | 
					
						
							|  |  |  | 	* Applying "Streamline lpfc error handling" patch from Christoph | 
					
						
							|  |  |  | 	  Hellwig (hch@infradead.org) with following modifications: fix | 
					
						
							|  |  |  | 	  mem leaks, remove some misplaced code that need not be there, | 
					
						
							|  |  |  | 	  print a message on exit (old code prints two (entry/exit)), make | 
					
						
							|  |  |  | 	  ret values consistent (either 1/0 or SUCCESS/FAILURE), keep all | 
					
						
							|  |  |  | 	  eh routines in a single file (lpfc_scsiport.c). | 
					
						
							|  |  |  | 	* Move contents of lpfc_module_param.h into lpfc_fcp.c. | 
					
						
							|  |  |  | 	* Changed sysfs attributes to CLASS_DEVICE_ATTRIBUTES (previously | 
					
						
							|  |  |  | 	  DEVICE_ATTRIBUTES). They now appear in | 
					
						
							|  |  |  | 	  /sys/class/scsi_host/hostx (previously in | 
					
						
							|  |  |  | 	  /sys/bus/pci/drivers/lpfc/devx). | 
					
						
							|  |  |  | 	* Removed lpfc_syfs.h and lpfc_sysfs.c. | 
					
						
							|  |  |  | 	* Cleanup of config params.  Throttle params have been removed. | 
					
						
							|  |  |  | 	  max_lun has been removed. max_target is replaced with a #define, | 
					
						
							|  |  |  | 	  lun_skip is removed.  Remove ipfc config params and related | 
					
						
							|  |  |  | 	  code. | 
					
						
							|  |  |  | 	* Changed DMABUF_t usage to struct lpfc_dmabuf. | 
					
						
							|  |  |  | 	* Downsizing iCfgParam structure to include a_string, a_low, a_hi | 
					
						
							|  |  |  | 	  and a_default values only. | 
					
						
							|  |  |  | 	* Free SCSI buf safety memory pool on shutdown to eliminate memory | 
					
						
							|  |  |  | 	  leak. | 
					
						
							|  |  |  | 	* Change lpfc_printf_log to a #define. Also include phba->brd_no | 
					
						
							|  |  |  | 	  and newline in the print string rather than in the #define. | 
					
						
							|  |  |  | 	* Remove code that optionally locates Host Group Pointers in host | 
					
						
							|  |  |  | 	  memory SLIM since this is no longer needed for PPC64, once | 
					
						
							|  |  |  | 	  CONFIG_PORT uses HBA's view of its BAR0. | 
					
						
							|  |  |  | 	* Removed the forward declarations of the sli functions and | 
					
						
							|  |  |  | 	  rearranging the code in lpfc_sli.c. | 
					
						
							|  |  |  | 	* Removed the preamble functionality from logging. | 
					
						
							|  |  |  | 	* Make lpfc_sli_hba_setup() return negative error codes on error | 
					
						
							|  |  |  | 	  and correct the comment left over in lpfc_fcp.c | 
					
						
							|  |  |  | 	* Removed the lpfc_loadtime variable. | 
					
						
							|  |  |  | 	* Put a space between all ifs and their open parens '('. | 
					
						
							|  |  |  | 	* Change Studly_Caps LPFC_SCSI_BUF_t to struct lpfc_scsi_buf. | 
					
						
							|  |  |  | 	* Fixed insmod hang after hardware error. | 
					
						
							|  |  |  | 	* Relocated scsi_host alloc to before we enable the interrupt | 
					
						
							|  |  |  | 	  handler | 
					
						
							|  |  |  | 	* Add .tmp_versions directory to Makefile clean target.  This | 
					
						
							|  |  |  | 	  directory is created in the 2.6.5+ build process (with Red Hat | 
					
						
							|  |  |  | 	  kernels at least). | 
					
						
							|  |  |  | 	* Changing phba->config to kmalloc lpfc_icfgparam and not | 
					
						
							|  |  |  | 	  *phba->config. This is manifesting itself as a panic in | 
					
						
							|  |  |  | 	  pci_release_region(). | 
					
						
							|  |  |  | 	* Fix for firmware download / board reset problem. | 
					
						
							|  |  |  | 	* Integrated patch from Christoph Hellwig (hch@infradead.org) to | 
					
						
							|  |  |  | 	  reorganize and cleanup lpfc_fcp.c | 
					
						
							|  |  |  | 	* Don't abort commands immediately when there is an RSCN event to | 
					
						
							|  |  |  | 	  give driver time to rediscover targets before the midlayer | 
					
						
							|  |  |  | 	  retries the SCSI commands. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040604 to 20040614 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.4 | 
					
						
							|  |  |  | 	* Removed lpfc_valid_lun function. | 
					
						
							|  |  |  | 	* Added scsi_buf safety pool to address scsi_buf failures in | 
					
						
							|  |  |  | 	  queuecommand under low memory conditions.  Allocations now come | 
					
						
							|  |  |  | 	  from kmalloc initially, but if kmalloc fails, the allocation | 
					
						
							|  |  |  | 	  comes from the safety pool. | 
					
						
							|  |  |  | 	* Modified lpfc_slave_alloc to only set the scsi_device->hostdata | 
					
						
							|  |  |  | 	  pointer if the driver has discovered the target.  This routine | 
					
						
							|  |  |  | 	  always returns success now as well since no error ever occurs in | 
					
						
							|  |  |  | 	  the alloc routine. | 
					
						
							|  |  |  | 	* Mask only info and warning messages.  Print all error messages | 
					
						
							|  |  |  | 	  irrespective of mask. | 
					
						
							|  |  |  | 	* Removing lpfc_log_chk_msg_disabled() | 
					
						
							|  |  |  | 	* Changed lpfc_printf_log to take struct lpfc_hba * directly | 
					
						
							|  |  |  | 	  instead of a "board number". | 
					
						
							|  |  |  | 	* Convert dma_sync_single to pci_dma_sync_single_for_{device/cpu}. | 
					
						
							|  |  |  | 	* Implemented new style log messages. The message strings are now | 
					
						
							|  |  |  | 	  embedded in the call to lpfc_printf_log. | 
					
						
							|  |  |  | 	* Decreased FLOGI discovery timeout to 20 seconds. | 
					
						
							|  |  |  | 	* On error in lpfc_pci_probe_one() return -1 and not 1. | 
					
						
							|  |  |  | 	* Allow for board numbers that are not sequential, paving the way | 
					
						
							|  |  |  | 	  for hotplug support. | 
					
						
							|  |  |  | 	* scsi_add_host() can fail, so wrap it around in an if(). Also | 
					
						
							|  |  |  | 	  initiate scsi_scan_host() after attaching the sysfs attributes. | 
					
						
							|  |  |  | 	* lpfc_release_version is used only in lpfc_ct.c, so move it there | 
					
						
							|  |  |  | 	  and mark it as static. | 
					
						
							|  |  |  | 	* Removed lpfc_sleep_ms and replaced with mdelay or schedule calls | 
					
						
							|  |  |  | 	  directly | 
					
						
							|  |  |  | 	* Removed all (struct list_head *) casts from clkData-related list | 
					
						
							|  |  |  | 	  handling in list_add, list_del macros. | 
					
						
							|  |  |  | 	* Removed EXPORT_SYMBOLs. | 
					
						
							|  |  |  | 	* Removed LPFC_MIN_QFULL and lpfc_qthrottle_up. | 
					
						
							|  |  |  | 	* Replace LPFCSCSITARGET_t with struct lpfc_target. | 
					
						
							|  |  |  | 	* Replace LPFCSCSILUN_t with struct lpfc_lun. | 
					
						
							|  |  |  | 	* Remove unused struct declarations (fcPathId and fcRouteId) from | 
					
						
							|  |  |  | 	  lpfc_scsi.h. | 
					
						
							|  |  |  | 	* Rewrite use of FC transport attributes. | 
					
						
							|  |  |  | 	* Fix crash when link is lost.  This was due to lpfc_delay_iodone | 
					
						
							|  |  |  | 	  calling list_del on an object that was never put on a list. | 
					
						
							|  |  |  | 	* Remove trailing spaces at the end of all lines. | 
					
						
							|  |  |  | 	* Set MAX_FCP_TARGET to 256 from 0xff.  Set MAX_FCP_LUN and | 
					
						
							|  |  |  | 	  MAX_FCP_CMDS to their decimal equivalents and updated | 
					
						
							|  |  |  | 	  documentation. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040526 to 20040604 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version number to 8.0.3 | 
					
						
							|  |  |  | 	* Completed sysfs FC transport support. | 
					
						
							|  |  |  | 	* Removed unused fields in SCSI LUN and SCSI Target structures: | 
					
						
							|  |  |  | 	  void *pTargetProto; void *pTargetOSEnv; void *pLunOSEnv; | 
					
						
							|  |  |  | 	* Modified list_for_each to list_for_each_entry. Modified | 
					
						
							|  |  |  | 	  list_for_each_safe to list_for_each_entry_safe. | 
					
						
							|  |  |  | 	* Remove lpfc_dfc.h file. | 
					
						
							|  |  |  | 	* Changed pHba->phba, pCommand->pcmd | 
					
						
							|  |  |  | 	* Changed plogi_ndlp -> plogindlp, pos_tmp->postmp, pRsp->prsp, | 
					
						
							|  |  |  | 	  pCmd->pcmd | 
					
						
							|  |  |  | 	* Changed pText -> ptext | 
					
						
							|  |  |  | 	* Changed p_tmp_buff -> ptmpbuff | 
					
						
							|  |  |  | 	* Changed pBufList -> pbuflist, pRsp -> prsp, pCmd -> pcmd | 
					
						
							|  |  |  | 	* Changed *pos_tmp -> *postmp, *p_mbuf -> *pmbuf | 
					
						
							|  |  |  | 	* Following changes are made to the SCSI fast path: Added | 
					
						
							|  |  |  | 	  DMA_BUF_t member to the lpfc_scsi_buf_t.  This will reduce a | 
					
						
							|  |  |  | 	  memory allocation in the scsi fast path.  Added check for | 
					
						
							|  |  |  | 	  targetp == NULL in the scsi fast path.  Increased number of | 
					
						
							|  |  |  | 	  scatter gather entries in lpfc_scsi_dma_ext to 4 from 3 and | 
					
						
							|  |  |  | 	  changed the size of lpfc_scsi_dma_ext to 264 | 
					
						
							|  |  |  | 	* Fixing some missing static lpfc_nportdisc.c. | 
					
						
							|  |  |  | 	* Reordered #include lines so that lpfc.h doesn't have to #include | 
					
						
							|  |  |  | 	  other header files. | 
					
						
							|  |  |  | 	* Remove lpfc_get_hba_sym_node_name() as a global EXPORT and make | 
					
						
							|  |  |  | 	  it static. | 
					
						
							|  |  |  | 	* Move struct clk_data definition from lpfc_hw.h to lpfc_sli.h. | 
					
						
							|  |  |  | 	* Changed LPFC_IOCBQ_t to struct lpfc_iocbq. | 
					
						
							|  |  |  | 	* Changed LPFC_SLI_RING_t to struct lpfc_sli_ring. | 
					
						
							|  |  |  | 	* Changed LPFC_NODELIST_t to struct lpfc_nodelist. | 
					
						
							|  |  |  | 	* Rearranged lpfc_nportdisc.c by moving state machine array | 
					
						
							|  |  |  | 	  (lpfc_disc_action) and the one function that uses it, | 
					
						
							|  |  |  | 	  lpfc_disc_state_machine, to the end of the file, removing the | 
					
						
							|  |  |  | 	  need for the raft of prototypes at the top. | 
					
						
							|  |  |  | 	* Changed LPFC_BINDLIST_t to struct lpfc_bindlist. | 
					
						
							|  |  |  | 	* Removed lpfc_issue_ct_rsp(), lpfc_sleep(), lpfc_add_bind(), | 
					
						
							|  |  |  | 	  lpfc_del_bind(), lpfc_sli_wake_mbox_wait() and | 
					
						
							|  |  |  | 	  lpfc_sli_issue_mbox_wait(). | 
					
						
							|  |  |  | 	* Fixed a large number of overly-long lines. | 
					
						
							|  |  |  | 	* Fixed some discovery problems: Introduced deferred ndlp removal | 
					
						
							|  |  |  | 	  when in DSM to avoid panic when in nested DMSs Fix NportId | 
					
						
							|  |  |  | 	  fffc01 handling to not relogin after LOGO fixed handling of LOGO | 
					
						
							|  |  |  | 	  on PLOGI issue. | 
					
						
							|  |  |  | 	* Changed SLI_CT_REQUEST to lpfc_sli_ct_request. | 
					
						
							|  |  |  | 	* Changed NAME_TYPE to struct lpfc_name. | 
					
						
							|  |  |  | 	* Changed lpfcCfgParam_t to struct lpfc_cfgparam. | 
					
						
							|  |  |  | 	* Changed LPFC_STAT_t to struct lpfc_stats. | 
					
						
							|  |  |  | 	* Changed HBAEVT_t to struct lpfc_hba_event. | 
					
						
							|  |  |  | 	* Changed Studly_Caps lpfcHBA_t to struct lpfc_hba. | 
					
						
							|  |  |  | 	* Removed no longer used tasklet_running flag. | 
					
						
							|  |  |  | 	* Removing *PSOME_VAR typedefs and using SOME_VAR* directly. | 
					
						
							|  |  |  | 	* Changing .use_clustering to ENABLE_CLUSTERING. | 
					
						
							|  |  |  | 	* Modify lpfc_queuecommand to return SCSI_MLQUEUE_HOST_BUSY when | 
					
						
							|  |  |  | 	  it can't queue a SCSI command.  Also, remove cmnds_in_flight | 
					
						
							|  |  |  | 	  member of struct lpfcHBA for 2.6 kernels as it was only needed | 
					
						
							|  |  |  | 	  to determine what to return from queuecommand. | 
					
						
							|  |  |  | 	* Change return type of lpfc_evt_iocb_free to void as it doesn't | 
					
						
							|  |  |  | 	  return anything. | 
					
						
							|  |  |  | 	* Remove unused cmnd_retry_list and in_retry members in struct | 
					
						
							|  |  |  | 	  lpfcHBA. | 
					
						
							|  |  |  | 	* Remove some instances of unneeded casting of kmalloc's return in | 
					
						
							|  |  |  | 	  lpfc_scsiport.c | 
					
						
							|  |  |  | 	* Remove lpfc_linux_attach() and lpfc_linux_detach(). Integrate | 
					
						
							|  |  |  | 	  them into lpfc_probe_one() and lpfc_release_one() respectively. | 
					
						
							|  |  |  | 	* Remove lpfc_num_iocbs, lpfc_num_bufs module parameters | 
					
						
							|  |  |  | 	* Remove #defines for NUM_NODES, NUM_BUFS and NUM_IOCBS | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040515 to 20040526 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changing version number to 8.0.2. | 
					
						
							|  |  |  | 	* Including dma-mapping.h as one of the include headers.  Also | 
					
						
							|  |  |  | 	  rearrange the #include order. | 
					
						
							|  |  |  | 	* Make functions static as appropriate. | 
					
						
							|  |  |  | 	* queuecommand() will now return SCSI_MLQUEUE_HOST_BUSY instead of | 
					
						
							|  |  |  | 	  1 to backpressure midlayer. | 
					
						
							|  |  |  | 	* Removed function prototypes for lpfc_start_timer() and | 
					
						
							|  |  |  | 	  lpfc_stop_timer() | 
					
						
							|  |  |  | 	* Changed timer support to be inline.  Clk_data is now declared | 
					
						
							|  |  |  | 	  right next to the corresponding timer_list entry so we don't | 
					
						
							|  |  |  | 	  have to allocate these clk_data dynamically. | 
					
						
							|  |  |  | 	* Add readls after writels to PCI space to flush the writes. | 
					
						
							|  |  |  | 	* Fix misspelled word "safety" in function names. | 
					
						
							|  |  |  | 	* Fix up comments in lpfc.conf for per HBA parameters to reflect | 
					
						
							|  |  |  | 	  new implementation. | 
					
						
							|  |  |  | 	* Change lpfc_proc_info handler to get the Nodename from | 
					
						
							|  |  |  | 	  fc_nodename and not fc_portname. | 
					
						
							|  |  |  | 	* Fix up some comments and whitespace in lpfc_fcp.c. | 
					
						
							|  |  |  | 	* Formatting changes: get rid of leading spaces in code | 
					
						
							|  |  |  | 	* Move discovery processing from tasklet to a kernel thread. | 
					
						
							|  |  |  | 	* Move ndlp node from unmap list to map list if ADISC completed | 
					
						
							|  |  |  | 	  successfully. | 
					
						
							|  |  |  | 	* Flush all the ELS IOCBs when there is a link event. | 
					
						
							|  |  |  | 	* LP9802 qdepth is twice the LP9802DC qdepth.  Delay | 
					
						
							|  |  |  | 	  elx_sched_init after READ_CONFIG to get max_xri from the | 
					
						
							|  |  |  | 	  firmware.  Reset ELX_CFG_DFT_HBA_Q_DEPTH to max_xri after | 
					
						
							|  |  |  | 	  READ_CONFIG | 
					
						
							|  |  |  | 	* Fix fc_get_cfg_parm() to be more robust and support embedded hex | 
					
						
							|  |  |  | 	  values.  The lpfc_param's are now defined as: | 
					
						
							|  |  |  | 	  lpfc_log_verbose="lpfc:0,lpfc0:0x10,lpfc1:4,lpfc100:0xffff" The | 
					
						
							|  |  |  | 	  "," delimter does not matter. It can be anything or not exist at | 
					
						
							|  |  |  | 	  all. ie param = "lpfc:0lpfc0:0x10.lpfc1:4txtlpfc100:0xffff" will | 
					
						
							|  |  |  | 	  also work.  Additionally the string is treated as case | 
					
						
							|  |  |  | 	  insensitive. | 
					
						
							|  |  |  | 	* Changed all usage of lpfc_find_lun_device() to lpfc_find_lun(). | 
					
						
							|  |  |  | 	* Removed unnecessary wrappers lpfc_find_lun_device() and | 
					
						
							|  |  |  | 	  lpfc_tran_find_lun(). | 
					
						
							|  |  |  | 	* Switch from using internal bus/id/lun to similar data from | 
					
						
							|  |  |  | 	  scsi_device structure. | 
					
						
							|  |  |  | 	* Eliminate one-line function lpfc_find_target() | 
					
						
							|  |  |  | 	* Added slave_alloc, slave_destory | 
					
						
							|  |  |  | 	* lpfc_scsi_cmd_start can now acquire lun pointer from | 
					
						
							|  |  |  | 	  scsi_device->hostdata, which is setup in slave_alloc. | 
					
						
							|  |  |  | 	* Eliminate unnecessary checking on every cmd just to see if we | 
					
						
							|  |  |  | 	  are accessing the device the first time. | 
					
						
							|  |  |  | 	* Remove assumption in lpfc_reset_lun_handler that a valid | 
					
						
							|  |  |  | 	  lpfc_scsi_buf is hung off of linux's scsi_cmnd->host_scribble | 
					
						
							|  |  |  | 	  when our reset is called. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040507 to 20040515 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Changed version to 8.0.1 | 
					
						
							|  |  |  | 	* Fixed crash on driver rmmod after error injection tests and | 
					
						
							|  |  |  | 	  lpfc_tasklet deadlock. | 
					
						
							|  |  |  | 	* Modified lpfc.conf to remove limit on number of support hosts | 
					
						
							|  |  |  | 	* Removed HBAAPI  | 
					
						
							|  |  |  | 	* Removed duplication of SCSI opcodes from lpfc_fcp.h that are | 
					
						
							|  |  |  | 	  available in scsi/scsi.h | 
					
						
							|  |  |  | 	* Rework module_param usage | 
					
						
							|  |  |  | 	* Added MODULE_PARAM_DESC for various module_params |

							|  |  |  | 	* Fix formatting of lpfc_driver | 
					
						
							|  |  |  | 	* Remove unnecessary memset to 0 of lpfcDRVR | 
					
						
							|  |  |  | 	* Attach driver attributes always unless pci_module_init failed | 
					
						
							|  |  |  | 	* Remove all one-line wrappers from lpfc_mem. | 
					
						
							|  |  |  | 	* Remove lpfc_sysfs_set_[show|store] as it is no longer needed | 
					
						
							|  |  |  | 	* Redo lpfc_sysfs_params_[show|store] to one value per attribute rule |

							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040429 to 20040507 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Change version to 8.0.0 | 
					
						
							|  |  |  | 	* Fix the number of cmd / rsp ring entries in lpfc_fcp.c to match | 
					
						
							|  |  |  | 	  the divisions setup in lpfc_hw.h. | 
					
						
							|  |  |  | 	* Remove phba->iflag reference. | 
					
						
							|  |  |  | 	* Several locking improvements. | 
					
						
							|  |  |  | 	* Remove functions lpfc_drvr_init_lock, lpfc_drvr_lock, | 
					
						
							|  |  |  | 	  lpfc_drvr_unlock and lpfc_hipri_*. | 
					
						
							|  |  |  | 	* Remove LPFC_DRVR_LOCK and LPFC_DRVR_UNLOCK macros. | 
					
						
							|  |  |  | 	* Make lpfc_info() use lpfc_get_hba_model_desc() instead of | 
					
						
							|  |  |  | 	  rewriting almost identical code. | 
					
						
							|  |  |  | 	* Fix 1 overly long line in each of lpfc_cfgparm.h, lpfc_ftp.c and | 
					
						
							|  |  |  | 	  lpfc_sli.c. | 
					
						
							|  |  |  | 	* Fix build for Red Hat 2.6.3 kernel by #defining MODULE_VERSION | 
					
						
							|  |  |  | 	  only if it isn't already defined. | 
					
						
							|  |  |  | 	* Change elx_sli_issue_mbox_wait to return correct error code to | 
					
						
							|  |  |  | 	  the caller. | 
					
						
							|  |  |  | 	* In some of the els completion routines, after calling | 
					
						
							|  |  |  | 	  lpfc_elx_chk_latt, driver ignores the return code of the | 
					
						
							|  |  |  | 	  lpfc_elx_chk_latt. This will prevent the discovery state machine | 
					
						
							|  |  |  | 	  restarting correctly when there are link events in the middle of | 
					
						
							|  |  |  | 	  discovery state machine running. Fix this by exiting discovery | 
					
						
							|  |  |  | 	  state machine if lpfc_els_chk_latt returns a non zero value. | 
					
						
							|  |  |  | 	* Removed MAX_LPFC_BRDS from lpfc_diag.h | 
					
						
							|  |  |  | 	* Removed unused first_check. | 
					
						
							|  |  |  | 	* Remove some unused fields and defines. | 
					
						
							|  |  |  | 	* Change lpfc-param names to lpfc_param. |

							|  |  |  | 	* Shorten length of some of the comment lines to make them more | 
					
						
							|  |  |  | 	  readable. | 
					
						
							|  |  |  | 	* Move FCP_* definitions to their own header file, lpfc_fcp.h. | 
					
						
							|  |  |  | 	* Remove unused prototypes from lpfc_crtn.h: fcptst, iptst, | 
					
						
							|  |  |  | 	  lpfc_DELAYMS. | 
					
						
							|  |  |  | 	* Remove duplicated prototypes from lpfc_crtn.h: | 
					
						
							|  |  |  | 	  lpfc_config_port_prep, lpfc_config_port_post, | 
					
						
							|  |  |  | 	  lpfc_hba_down_prep. | 
					
						
							|  |  |  | 	* Removed some unused export_symbols. | 
					
						
							|  |  |  | 	* Install driver files into */drivers/scsi/lpfc instead of | 
					
						
							|  |  |  | 	  */drivers/scsi. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040426 to 20040429 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Declared export symbol lpfc_page_alloc and lpfc_page_free | 
					
						
							|  |  |  | 	* Changed lpfc version number to 6.98.3 | 
					
						
							|  |  |  | 	* Move the definition of MAX_LPFC_BRDS to the only header file | 
					
						
							|  |  |  | 	  that uses it (lpfc_diag.h). | 
					
						
							|  |  |  | 	* Change lpfc_sli_wake_iocb_wait to do a regular wake_up since | 
					
						
							|  |  |  | 	  lpfc_sli_issue_iocb_wait now sleeps uninterruptible. | 
					
						
							|  |  |  | 	* Replace list_for_each() with list_for_each_safe() when a list | 
					
						
							|  |  |  | 	  element could be deleted. | 
					
						
							|  |  |  | 	* Fix IOCB memory leak | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040416 to 20040426 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Change lpfc_config_port_prep() to interpret word 4 of the DUMP | 
					
						
							|  |  |  | 	  mbox response as a byte-count | 
					
						
							|  |  |  | 	* Add info attribute to sysfs | 
					
						
							|  |  |  | 	* Minor formatting (spaces to tabs) cleanup in lpfc_sched.h | 
					
						
							|  |  |  | 	* Remove unused log message number 732 | 
					
						
							|  |  |  | 	* Completing MODULE_PARM -> module_param changes | 
					
						
							|  |  |  | 	* Removed unused targetenable module parameter | 
					
						
							|  |  |  | 	* Removed locks from lpfc_sli_issue_mbox_wait routine | 
					
						
							|  |  |  | 	* Removed code that retry 29,00 check condition | 
					
						
							|  |  |  | 	* Removed code that manipulates rspSnsLen. | 
					
						
							|  |  |  | 	* Fix use of lun-q-depth config param | 
					
						
							|  |  |  | 	* Fix severity inconsistency with log message 249 | 
					
						
							|  |  |  | 	* Removed lpfc_max_target from lpfc_linux_attach | 
					
						
							|  |  |  | 	* Replace references to lpfcDRVR.pHba[] with lpfc_get_phba_by_inst() | 
					
						
							|  |  |  | 	* Change lpfc_param to lpfc-param | 
					
						
							|  |  |  | 	* Partially removed 32 HBA restriction within driver.  Incorported | 
					
						
							|  |  |  | 	  lpfc_instcnt, lpfc_instance[], and pHba[] into lpfcDRVR | 
					
						
							|  |  |  | 	  structure Added routines lpfc_get_phba_by_inst() | 
					
						
							|  |  |  | 	  lpfc_get_inst_by_phba() lpfc_check_valid_phba() | 
					
						
							|  |  |  | 	* Turn on attributes "set" & "params" by default. | 
					
						
							|  |  |  | 	* Further formatting/whitespace/line length cleanup on: lpfc_ct.c | 
					
						
							|  |  |  | 	  lpfc_els.c lpfc_fcp.c lpfc_hbadisc.c lpfc_init.c lpfc_ipport.c | 
					
						
							|  |  |  | 	  lpfc_mbox.c lpfc_nportdisc.c lpfc_sched.c lpfc_sched.h | 
					
						
							|  |  |  | 	  lpfc_scsi.h lpfc_scsiport.c lpfc_sli.c and lpfc_sli.h | 
					
						
							|  |  |  | 	* Add log message 249 to log any unsupported device addressing | 
					
						
							|  |  |  | 	  modes encountered. | 
					
						
							|  |  |  | 	* Add support for 256 targets and 256 LUNs | 
					
						
							|  |  |  | 	* Fixed panic in lpfc_linkdown. | 
					
						
							|  |  |  | 	* Removed (struct list_head*) casting in several calls to list_del | 
					
						
							|  |  |  | 	* Free irq reservation and kill running timers when insmod or | 
					
						
							|  |  |  | 	  modprobe are killed via ctrl-c | 
					
						
							|  |  |  | 	* Remove drivers/scsi from include path | 
					
						
							|  |  |  | 	* Wrap use of log message 311 in macro | 
					
						
							|  |  |  | 	* Detect failure return from pci_map_sg call in lpfc_os_prep_io | 
					
						
							|  |  |  | 	* Fix use-after-free of IOCB in lpfc_sli_process_sol_iocb which | 
					
						
							|  |  |  | 	  was causing an Oops on 2.6.5 kernel. | 
					
						
							|  |  |  | 	* Cleanup use of several gotos not used for error exit. | 
					
						
							|  |  |  | 	* Replace memcpy_toio() and memcpy_toio() with endian-dependent | 
					
						
							|  |  |  | 	  lpfc_memcpy_to_slim() and lpfc_memcpy_from_slim() so that for | 
					
						
							|  |  |  | 	  big endian hosts like PPC64, the SLIM is accessed 4 bytes at a | 
					
						
							|  |  |  | 	  time instead of as a byte-stream. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040409 to 20040416 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* The scsi_register and scsi_alloc_host OS calls can fail and | 
					
						
							|  |  |  | 	  return a zero-valued host pointer.  A ctrl-C on 2.6 kernels | 
					
						
							|  |  |  | 	  during driver load will cause this and the driver to panic. | 
					
						
							|  |  |  | 	  Fixed this bug.  Also found a bug in the error_x handling with | 
					
						
							|  |  |  | 	  lpfc_sli_hba_down - it was in the wrong place and the driver | 
					
						
							|  |  |  | 	  lock was not held, but needed to be (in lpfc_linux_attach) Fixed | 
					
						
							|  |  |  | 	  both.  Did some minor comment clean up. | 
					
						
							|  |  |  | 	* Removed unwanted (void *) castings. | 
					
						
							|  |  |  | 	* Replace define of INVALID_PHYS, with kernel 2.6.5's | 
					
						
							|  |  |  | 	  dma_mapping_error() and add a inline function for earlier | 
					
						
							|  |  |  | 	  kernels.  Remove lpfc_bad_scatterlist(). | 
					
						
							|  |  |  | 	* Clean up formatting in hbaapi.h, lpfc.h, lpfc_cfgparm.h, | 
					
						
							|  |  |  | 	  lpfc_crtn.h, lpfc_ct.c, lpfc_diag.h, lpfc_disc.h, lpfc_els.c, | 
					
						
							|  |  |  | 	  lpfc_fcp.c, lpfc_hbadisc.c, lpfc_hw.h, lpfc_init.c, | 
					
						
							|  |  |  | 	  lpfc_ipport.c, lpfc_logmsg.c, lpfc_logmsg.h and lpfc_scsiport.c | 
					
						
							|  |  |  | 	  - mostly replacing groups of 8 spaces with hard tabs and keeping | 
					
						
							|  |  |  | 	  lines to 80 column max.. | 
					
						
							|  |  |  | 	* Removed LPFC_DRVR_LOCK call from lpfc_unblock_requests for 2.4 | 
					
						
							|  |  |  | 	  kernels.  The lpfc_scsi_done routine already unlocks the driver | 
					
						
							|  |  |  | 	  lock since it expects this lock to be held. | 
					
						
							|  |  |  | 	* Removed global lock capabilities from driver lock routines | 
					
						
							|  |  |  | 	* Remove SA_INTERRUPT flag from request_irq | 
					
						
							|  |  |  | 	* Move dma_addr_t cast inside of getPaddr macro as everywhere | 
					
						
							|  |  |  | 	  getPaddr is used, the return is cast to dma_addr_t. | 
					
						
							|  |  |  | 	* Clean up formatting in lpfc_sli.c and lpfc_sysfs.c - mostly | 
					
						
							|  |  |  | 	   replacing groups of 8 spaces with hard tabs and keeping lines | 
					
						
							|  |  |  | 	   to 80 column max. | 
					
						
							|  |  |  | 	* Fix build for RHEL 2.1 BOOT kernels by always #including | 
					
						
							|  |  |  | 	  interrupt.h in lpfc.h. | 
					
						
							|  |  |  | 	* Fix RHEL 3 build by #defining EXPORT_SYMTAB. | 
					
						
							|  |  |  | 	* Replace sprintf with snprintf in lpfc_proc_info. | 
					
						
							|  |  |  | 	* Fix build warnings on 2.6 kernels - remove no longer used calls | 
					
						
							|  |  |  | 	  to  character device initialization. | 
					
						
							|  |  |  | 	* Initial support code for discovery in tasklet conversion. | 
					
						
							|  |  |  | 	* Removing char interface and ioctl code. | 
					
						
							|  |  |  | 	* Change all elx prefixes to lpfc | 
					
						
							|  |  |  | 	* Replace lpfc_write_slim() & lpfc_read_slim() with memcpy_toio(), | 
					
						
							|  |  |  | 	  memcpy_fromio(), writel() & readl(). | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | Changes from 20040402 to 20040409 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 	* Replaced lpfc_read_hbaregs_plus_offset and | 
					
						
							|  |  |  | 	  lpfc_write_hbaregs_plus_offset functions with readl and writel. | 
					
						
							|  |  |  | 	* Get rid of long mdelay's in insmod path | 
					
						
							|  |  |  | 	* Changed the way our pci_device_id structures are initialized | 
					
						
							|  |  |  | 	* Replace lpfc_read/write_CA/HA/HC/HS with calls to readl() & | 
					
						
							|  |  |  | 	  writel() directly. | 
					
						
							|  |  |  | 	* Increase SLI2_SLIM to 16K Increase cmd / rsp IOCBs accordingly | 
					
						
							|  |  |  | 	* Removed lpfc_els_chk_latt from the lpfc_config_post function. | 
					
						
							|  |  |  | 	  lpfc_els_chk_latt will enable the link event interrupts when | 
					
						
							|  |  |  | 	  flogi is pending which causes two discovery state machines | 
					
						
							|  |  |  | 	  running parallely. | 
					
						
							|  |  |  | 	* Add pci_disable_device to unload path. | 
					
						
							|  |  |  | 	* Move lpfc_sleep_event from lpfc_fcp.c to lpfc_util_ioctl.c | 
					
						
							|  |  |  | 	* Call dma_map_single() & pci_map_single() directly instead of via | 
					
						
							|  |  |  | 	  macro lpfc_pci_map().  Allow address 0 for PPC64. | 
					
						
							|  |  |  | 	* Change sleep to uninterruptible in lpfc_sli_issue_icob_wait | 
					
						
							|  |  |  | 	  because this function doesn't handle signals. | 
					
						
							|  |  |  | 	* Move lpfc_wakeup_event from lpfc_fcp.c to lpfc_ioctl.c | 
					
						
							|  |  |  | 	* Remove unneeded #include <linux/netdevice.h> | 
					
						
							|  |  |  | 	* Remove unused clock variables lpfc_clkCnt and lpfc_sec_clk. | 
					
						
							|  |  |  | 	* Get rid of capitalization of function names. | 
					
						
							|  |  |  | 	* Removed lpfc_addr_sprintf. | 
					
						
							|  |  |  | 	* Implemented gotos in lpfc_linux_attach for error cases. | 
					
						
							|  |  |  | 	* Replace mlist->dma.list = dmp->dma.list; to mlist = dmp. | 
					
						
							|  |  |  | 	* Remove functions lpfc_get_OsNameVersion and elx_wakeup. Change | 
					
						
							|  |  |  | 	  elx_wakeup to wake_up_interruptible | 
					
						
							|  |  |  | 	* Add function lpfc_get_os_nameversion and change | 
					
						
							|  |  |  | 	  lpfc_get_OsNameVersion to lpfc_get_os_nameversion. | 
					
						
							|  |  |  | 	* Remove lpfc_get_OsNameVersion | 
					
						
							|  |  |  | 	* Change driver name to a consistent lpfc in every visible place. | 
					
						
							|  |  |  | 	* Fix build warning: removed unused variable ret in lpfc_fdmi_tmo. | 
					
						
							|  |  |  | 	* Remove lpfc_utsname_nodename_check function | 
					
						
							|  |  |  | 	* Remove functions lpfc_register_intr and lpfc_unregister_intr | 
					
						
							|  |  |  | 	* Fill in owner field in lpfc_ops file_operations struct and | 
					
						
							|  |  |  | 	  remove now unnecessary open and close entry points. | 
					
						
							|  |  |  | 	* Change function name prefixes from elx_ to lpfc_ | 
					
						
							|  |  |  | 	* Remove special case check for TUR in elx_os_prep_io() | 
					
						
							|  |  |  | 	* Renamed elx_scsi.h to lpfc_scsi.h | 
					
						
							|  |  |  | 	* Renamed elx_sched.h to lpfc_sched.h | 
					
						
							|  |  |  | 	* Renamed elx_mem.h to lpfc_mem.h | 
					
						
							|  |  |  | 	* Renamed elx_sli.h to lpfc_sli.h | 
					
						
							|  |  |  | 	* Renamed elx_logmsg.h to lpfc_logmsg.h | 
					
						
							|  |  |  | 	* Renamed elx.h to lpfc.h | 
					
						
							|  |  |  | 	* Renamed elx_sli.c to lpfc_sli.c | 
					
						
							|  |  |  | 	* Renamed elx_sched.c to lpfc_sched.c | 
					
						
							|  |  |  | 	* Renamed elx_mem.c to lpfc_mem.c | 
					
						
							|  |  |  | 	* Renamed elx_logmsg.c to lpfc_logmsg.c | 
					
						
							|  |  |  | 	* Renamed lpfcLINUXfcp.c lpfc_fcp.c | 
					
						
							|  |  |  | 	* Renamed elx_clock.c to lpfc_clock.c | 
					
						
							|  |  |  | 	* Reduce stack usage in lpfc_info(). | 
					
						
							|  |  |  | 	* Move lpip_stats structure from lpfc_hba.h to lpfc_ip.h. | 
					
						
							|  |  |  | 	* Move lpfc_stats and HBAEVT_t structures from lpfc_hba.h to | 
					
						
							|  |  |  | 	  lpfc.h | 
					
						
							|  |  |  | 	* Remove lpfc_hba.h | 
					
						
							|  |  |  | 	* Remove duplicate rc definitions from  | 
					
						
							|  |  |  | 	* Removed code which used next pointer to store mbox structure. | 
					
						
							|  |  |  | 	* Cleaned up list iterations. | 
					
						
							|  |  |  | 	* Removed non list manipulation of the next pointers. |

							|  |  |  | 	* Replaced casting from list_head with list_entry macro. | 
					
						
							|  |  |  | 	* Added ct_ndlp_context field to the ELX_IOCBQ_t. | 
					
						
							|  |  |  | 	* Do not use DMABUf_t list to store ndlp context | 
					
						
							|  |  |  | 	* Return 0 from lpfc_process_iotcl_util() when ELX_INITBRDS | 
					
						
							|  |  |  | 	  succeeds. | 
					
						
							|  |  |  | 	* remove elx_os_scsiport.h | 
					
						
							|  |  |  | 	* Do not use DMABUf_t list to hold rpi context | 
					
						
							|  |  |  | 	* Replace elx_cfg_* names with lpfc_cfg-* |

							|  |  |  | 	  lines). | 
					
						
							|  |  |  | 	* Remove unused elxclock declaration in elx_sli.h. | 
					
						
							|  |  |  | 	* Since everywhere IOCB_ENTRY is used, the return value is cast, |

							|  |  |  | 	* Remove elx_util.h and replace elx_disc.h with lpfc_disc.h | 
					
						
							|  |  |  | 	* Implemented the Linux list macros in the discovery code. | 
					
						
							|  |  |  | 	  Also moved elx_disc.h contents into lpfc_disc.h | 
					
						
							|  |  |  | 	* Unused variable cleanup | 
					
						
							|  |  |  | 	* Use Linux list macros for DMABUF_t | 
					
						
							|  |  |  | 	* Break up ioctls into 3 sections, dfc, util, hbaapi | 
					
						
							|  |  |  | 	  rearranged code so this could be easily seperated into a | 
					
						
							|  |  |  | 	  differnet module later All 3 are currently turned on by | 
					
						
							|  |  |  | 	  defines in lpfc_ioctl.c LPFC_DFC_IOCTL, LPFC_UTIL_IOCTL, | 
					
						
							|  |  |  | 	  LPFC_HBAAPI_IOCTL | 
					
						
							|  |  |  | 	* Misc cleanup: some goto's; add comments; clarify function | 
					
						
							|  |  |  | 	  args | 
					
						
							|  |  |  | 	* Added code to use list macro for ELXSCSITARGET_t. | 
					
						
							|  |  |  | 	* New list implementation for ELX_MBOXQ_t | 
					
						
							|  |  |  | 	* Cleaned up some list_head casting. | 
					
						
							|  |  |  | 	* Put IPFC ifdef around two members of struct lpfc_nodelist. | 
					
						
							|  |  |  | 	* Cleaned up iocb list using list macros and list_head data | 
					
						
							|  |  |  | 	  structure. | 
					
						
							|  |  |  | 	* lpfc_online() was missing some timer routines that were | 
					
						
							|  |  |  | 	  started by lpfc_linux_attach().  These routines are now also | 
					
						
							|  |  |  | 	  started by lpfc_online().  lpfc_offline() only stopped | 
					
						
							|  |  |  | 	  els_timeout routine.  It now stops all timeout routines | 
					
						
							|  |  |  | 	  associated with that hba. | 
					
						
							|  |  |  | 	* Replace seperate next and prev pointers in struct | 
					
						
							|  |  |  | 	  lpfc_bindlist with list_head type.  In elxHBA_t, replace | 
					
						
							|  |  |  | 	  fc_nlpbind_start and _end with fc_nlpbind_list and use | 
					
						
							|  |  |  | 	  list_head macros to access it. | 
					
						
							|  |  |  | 	* Fix ulpStatus for aborting I/Os overlaps with newer firmware | 
					
						
							|  |  |  | 	  ulpStatus values | 
					
						
							|  |  |  | 	* Rework params_show/store to be consistent as the other | 
					
						
							|  |  |  | 	  routines.  Remove generic'ness and rely on set attribute. | 
					
						
							|  |  |  | 	* Remove unused log message. | 
					
						
							|  |  |  | 	* Collapse elx_crtn.h and prod_crtn.h into lpfc_crtn.h | 
					
						
							|  |  |  | 	* Ifdef Scheduler specific routines | 
					
						
							|  |  |  | 	* Removed following ununsed ioclt's: ELX_READ_IOCB | 
					
						
							|  |  |  | 	  ELX_READ_MEMSEG ELX_READ_BINFO ELX_READ_EINVAL ELX_READ_LHBA | 
					
						
							|  |  |  | 	  ELX_READ_LXHBA ELX_SET ELX_DBG LPFC_TRACE  | 
					
						
							|  |  |  | 	* Removed variable fc_dbg_flg | 
					
						
							|  |  |  | 	* Fixed a bug where HBA_Q_DEPTH was set incorrectly for | 
					
						
							|  |  |  | 	  3-digit HBAs.  Also changed can_queue so midlayer will only | 
					
						
							|  |  |  | 	  send (HBA_Q_DEPTH - 10) cmds. | 
					
						
							|  |  |  | 	* Clean up code in the error path, check condition.  Remove | 
					
						
							|  |  |  | 	  ununsed sense-related fields in lun structure. | 
					
						
							|  |  |  | 	* Added code for safety pools for following objects: mbuf/bpl, | 
					
						
							|  |  |  | 	  mbox, iocb, ndlp, bind | 
					
						
							|  |  |  | 	* Wrapped '#include <elx_sched.h>' in '#ifdef USE_SCHEDULER'. | 
					
						
							|  |  |  | 	* Fixed 'make clean' target. | 
					
						
							|  |  |  |         * Build now ignores elx_sched.o, and includes lpfc_sysfs.o. | 
					
						
							|  |  |  | 	* Wrapped lpfndd.o target in BUILD_IPFC ifdef. | 
					
						
							|  |  |  | 	* Removed elx_os.h inclusion in implementation files. | 
					
						
							|  |  |  | 	* Removed ELX_OS_IO_t data structure and put data direction | 
					
						
							|  |  |  | 	  and non scatter/gather physical address into the scsi buffer | 
					
						
							|  |  |  | 	  structure directly.  Moved DRVR_LOCK, putPaddr, getPaddr | 
					
						
							|  |  |  | 	  macros and some defines into elx.h since they are required | 
					
						
							|  |  |  | 	  by the whole driver. | 
					
						
							|  |  |  | 	* Migrated following ioctls (debug) ELX_DISPLAY_PCI_ALL | 
					
						
							|  |  |  | 	  ELX_DEVP ELX_READ_BPLIST ELX_RESET_QDEPTH ELX_STAT. | 
					
						
							|  |  |  | 	* Step 1 of attempt to move all Debug ioctls to sysfs. | 
					
						
							|  |  |  | 	  Implemented the following IOCTLs in sysfs: ELX_WRITE_HC | 
					
						
							|  |  |  | 	  ELX_WRITE_HS ELX_WRITE_HA ELX_WRITE_CA ELX_READ_HC | 
					
						
							|  |  |  | 	  ELX_READ_HS ELX_READ_HA ELX_READ_CA ELX_READ_MB ELX_RESET | 
					
						
							|  |  |  | 	  ELX_READ_HBA ELX_INSTANCE ELX_LIP.  Also introduced | 
					
						
							|  |  |  | 	  attribute "set" to be used in conjuction with the above | 
					
						
							|  |  |  | 	  attributes. | 
					
						
							|  |  |  | 	* Removed DLINK, enque and deque declarations now that clock | 
					
						
							|  |  |  | 	  doesn't use them anymore | 
					
						
							|  |  |  | 	* Separated install rule so that BUILD_IPFC has to be set when | 
					
						
							|  |  |  | 	  make is called in order for the install rule to attempt to | 
					
						
							|  |  |  | 	  copy the lpfndd.o driver.  This change fixes a bug that | 
					
						
							|  |  |  | 	  occurs because the install rule by default attempted to | 
					
						
							|  |  |  | 	  install lpfndd.o, whereas the default make rule did not by | 
					
						
							|  |  |  | 	  default build lpfndd.o. | 
					
						
							|  |  |  | 	* Keep track if hbaapi index numbers need to be refreshed. | 
					
						
							|  |  |  | 	* Removed prod_os.h from include list. | 
					
						
							|  |  |  | 	* Removed LPFC_LOCK and LPFC_UNLOCK macros.  Added OS calls | 
					
						
							|  |  |  | 	  into elx_os_scsiport.c.  This file is now empty. | 
					
						
							|  |  |  | 	* Added spin_lock_irqsave and spin_unlock_irqrestore calls | 
					
						
							|  |  |  | 	  into code directly and removed LPFC_LOCK_ and _UNLOCK_ | 
					
						
							|  |  |  | 	  macros | 
					
						
							|  |  |  | 	* Remove references to "elx_clock.h" | 
					
						
							|  |  |  | 	* Added utsname.h to include list.  The previous checkin to | 
					
						
							|  |  |  | 	  elx_os.h removed its inclusion of utsname.h since there is | 
					
						
							|  |  |  | 	  precious little in the file.  However, lpfcLINUXfcp.c needs | 
					
						
							|  |  |  | 	  it and now has it. | 
					
						
							|  |  |  | 	* Removed some commented-out code | 
					
						
							|  |  |  | 	* Removed elx_lck_t data structure, stray elxDRVR_t type, and | 
					
						
							|  |  |  | 	  include from file.  No longer used. | 
					
						
							|  |  |  | 	* Removed two PCI Sync defines.  Removed includes - not | 
					
						
							|  |  |  | 	  needed.  Cleaned up macro lines. | 
					
						
							|  |  |  | 	* Added two functions from elxLINUXfcp.c.  These functions | 
					
						
							|  |  |  | 	  were IPFC specific. | 
					
						
							|  |  |  | 	* Removed hipri lock abstractions and added OS call into code. | 
					
						
							|  |  |  | 	  Removed elx_lck_t and added spinlock_t directly. Moved two | 
					
						
							|  |  |  | 	  IPFC functions into lpfc_ipport.c | 
					
						
							|  |  |  | 	* Moved IP specific structures to lpfc_ip.h file. | 
					
						
							|  |  |  | 	* lpfc_ipfarp_timeout() uses system timer.  Remove all usages | 
					
						
							|  |  |  | 	  of old internal clock support. | 
					
						
							|  |  |  | 	* Made changes to compile without IPFC support for the default | 
					
						
							|  |  |  | 	  build.  Added ifdef IPFC for all lpfc_ip.h includes. | 
					
						
							|  |  |  | 	* Patched elx_free_scsi_buf | 
					
						
							|  |  |  |   	* Removed elx_sched.o from 2.6 dependencies | 
					
						
							|  |  |  | 	* Reworked lpfc_pcimap. | 
					
						
							|  |  |  | 	* Use Linux swap macros to replace ELX swapping macros | 
					
						
							|  |  |  | 	  (SWAP_SHORT, SWAP_LONG, SWAP_DATA, SWAP_DATA16, | 
					
						
							|  |  |  | 	  PCIMEM_SHORT, PCIMEM_LONG, PCIMEM_DATA). |

							|  |  |  | 	* Moved location of pci.h include. | 
					
						
							|  |  |  | 	* Restored elx_lck_t types in elxHBA_t. | 
					
						
							|  |  |  | 	* Removed elx_pci_dma_sync call.  Also removed some PCI | 
					
						
							|  |  |  | 	  defines from elx_hw.h and removed the spinlock_t locks that | 
					
						
							|  |  |  | 	  are no longer used in elx.h | 
					
						
							|  |  |  | 	* elx_iodone() now uses system timer. | 
					
						
							|  |  |  |   	* elx_qfull_retry() now uses system timer. | 
					
						
							|  |  |  | 	* lpfc_put_buf(), lpfc_ip_xri_timeout() and | 
					
						
							|  |  |  | 	  lpfc_ip_timeout_handler() now use system timer. | 
					
						
							|  |  |  | 	* lpfc_fdmi_tmo() and lpfc_qthrottle_up() now use system | 
					
						
							|  |  |  |           timer. | 
					
						
							|  |  |  | 	* Removed num_bufs and num_iocbs configuration parameters. | 
					
						
							|  |  |  | 	* Fixed a memory corruption bug. This was caused by a memory | 
					
						
							|  |  |  | 	  write to ndlp structure from lpfc_cmpl_els_acc function. | 
					
						
							|  |  |  | 	  This ndlp structure was freed from lpfc_els_unsol_event. | 
					
						
							|  |  |  | 	* lpfc_disc_timeout() and lpfc_establish_link_tmo() now use | 
					
						
							|  |  |  | 	  system timer.  Also update lpfc_els_retry_delay() to do a | 
					
						
							|  |  |  | 	  single lock release at the end. | 
					
						
							|  |  |  | 	* Remove use of PAN (pseudo adapter number). | 
					
						
							|  |  |  | 	* Reintroduced usage of the cross compiler for building on | 
					
						
							|  |  |  | 	  ppc64 to remove build errors that were cropping up when | 
					
						
							|  |  |  | 	  using the standard gcc compiler. | 
					
						
							|  |  |  | 	* Fix no-unlock-before return in lpfc_els_retry_delay which was | 
					
						
							|  |  |  | 	  causing  a deadlock on insmod in some environments. | 
					
						
							|  |  |  | 	* Minor format changes fix up comments | 
					
						
							|  |  |  | 	* Create utility clock function elx_start_timer() and | 
					
						
							|  |  |  | 	  elx_stop_timer().  All timeout routines now use these common | 
					
						
							|  |  |  | 	  routines. | 
					
						
							|  |  |  | 	* Minor formating changes fix up comments | 
					
						
							|  |  |  | 	* Minor formatting changes get rid of failover defines for |

							|  |  |  | 	* Comment out lpfndd.o modules_install section as lpfndd.o is | 
					
						
							|  |  |  | 	  not generated if CONFIG_NET_LPFC is not set. Also refer to | 
					
						
							|  |  |  | 	  BASEINCLUDE only in out of kernel source module builds as it | 
					
						
							|  |  |  | 	  will not exist otherwise. | 
					
						
							|  |  |  | 	* Removed unused malloc counters from lpfcLINUXfcp.c. |

							|  |  |  | 	  kernel compile. Does not recompile all files on every | 
					
						
							|  |  |  | 	  build. Uses the kernel build's definitions of CFLAGS, | 
					
						
							|  |  |  | 	  MODFLAGS etc. Removed "make rpm" option. | 
					
						
							|  |  |  | 	* Removed unused #defines CLOSED, DEAD, OPENED, NORMAL_OPEN | 
					
						
							|  |  |  | 	  and unneeded #include of elx_sched.h in elx.h. | 
					
						
							|  |  |  | 	* Several log message updates |

							|  |  |  | 	* Removed function calls for mapping bar registers and allocating | 
					
						
							|  |  |  | 	  kernel virtual memory mappings to the mapped bars Removed | 
					
						
							|  |  |  | 	  prototypes, lpfc_driver_cache_line, and pci_bar1_map rename to | 
					
						
							|  |  |  | 	  pci_bar2_map. |

							|  |  |  | 	  internal clock support. | 
					
						
							|  |  |  | 	* Move remaining message logging functions in elx_util.c to |

							|  |  |  | 	* Sysfs new display format. Also added write functionality. You | 
					
						
							|  |  |  | 	  can [ echo "0 log_verbose 3" > | 
					
						
							|  |  |  | 	  /sys/bus/pci/drivers/lpfc/params]. Hex support yet to be added. | 
					
						
							|  |  |  | 	* Removed several #ifdef powerpc, including for a discovery issue | 
					
						
							|  |  |  | 	  in lpfc_ValidLun() | 
					
						
							|  |  |  | 	* Change elx_printf_log to use vsprintf. | 
					
						
							|  |  |  | 	* Added lpfc_compat.h provides macros to aid compilation in the | 
					
						
							|  |  |  | 	  Linux 2.4 kernel over various platform architectures.  Initially | 
					
						
							|  |  |  | 	  support mapping to a DMA address. | 
					
						
							|  |  |  | 	* Removed memory pool for nlp/bind buffers and use kmalloc/kfree | 
					
						
							|  |  |  | 	  directly. | 
					
						
							|  |  |  | 	* Removed memory pool for iocb buffers and use kmalloc/kfree |

							|  |  |  | 	* Fix a 2.6 kernel check to be >= 2.6.0 instead of > (was missing | 
					
						
							|  |  |  | 	  2.6.0). | 
					
						
							|  |  |  | 	* Remove elx_printf and elx_str_sprintf. Replace elx_print with | 
					
						
							|  |  |  | 	  printk. | 
					
						
							|  |  |  | 	* Replace elx_printf with printk. | 
					
						
							|  |  |  | 	* Replace elx_str_sprintf with sprintf. |
