linux 内核源代码

	  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
	  to nothing more then the lpfc_nodelist pointer.
	* 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 -
