linux 内核源代码

	  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 ([e-mail]) as follows
	  "[PATCH] use scsi host private data in ->proc_info.  
	* Applied patch from Christoph Hellwig ([e-mail]) 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.

	  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 ([e-mail]) 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

	* Changed version number to 8.0.6
	* Removed internal report LUNs usage.  Removed functions:
	  lpfc_disc_issue_rptlun, lpfc_disc_cmpl_rptlun,
	  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.

	* Moving the persistent binding variables to new file
	  lpfc_defaults.c
	* Changed LPFC_SCSI_BUF_t to struct lpfc_scsi_buf.
	* Moved config specific code from probe_one() into

	  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.

	  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 ([e-mail]) 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.
