+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
+ 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 -
+ 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
+
+ * 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.
+
+Changes from 20040614 to 20040709
+
+ * Changed version number to 8.0.5
+ * Make lpfc_info static.
+ * Make lpfc_get_scsi_buf static.
+ * Print a warning if pci_set_mwi returns an error.
+ * Changed SERV_PARM to struct serv_parm.
+ * Changed LS_RJT to struct ls_rjt.
+ * Changed CSP to struct csp.
+ * Changed CLASS_PARMS to struct class_parms.
+ * Some cosmetic coding style cleanups to lpfc_fcp.c.

+ LINK_[UP|DOWN] and RSCN events.
+ * Get rid of delay_iodone timer.
+ * Remove qfull timers and qfull logic.
+ * Convert mbox_tmo, nlp_xri_tmo to 1 argment clock handler
+ * Removed duplicate extern defs of the bind variables.
+ * Streamline usage of the defines CLASS2 and CLASS3, removing
+ un-necessary checks on config[LPFC_CFG_FCP_CLASS].
+ * 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
+ config_setup(). Removing a redundant check on scandown value
+ from bind_setup() as this is already done in config_setup().
+ * Changed LPFC_SLI_t to struct lpfc_sli.

+ 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.

+ * 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

+ * 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

+
+Changes from 20040429 to 20040507
+
+ * Change version to 8.0.0

+ 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.

+
+ * 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
+

+ 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

+ modes encountered.
+ * Add support for 256 targets and 256 LUNs

+ * 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().

+ 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(),

+ * 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.

+ * 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

+ 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.

+ * 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

+ * Cleaned up list iterations.
+ * Removed non list manipulation of the next pointers.
+ * Change list_del()/INIT_LIST_HEAD sequences to list_del_init()

+ * 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

+ 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.

+ 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.

+ 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.

+
+LPFC Driver Release Notes:
+
+=============================================================================
+
+
+ IMPORTANT:
+
+ Starting in the 8.0.17 release, the driver began to be targeted strictly
+ toward the upstream kernel. As such, we removed #ifdefs for older kernels
+ (pre 2.6.10). The 8.0.16 release should be used if the driver is to be
+ run on one of the older kernels.
+
+ The proposed modifications to the transport layer for FC remote ports
+ and extended attribute support is now part of the upstream kernel
+ as of 2.6.12. We no longer need to provide patches for this support,
+ nor a *full* version which has old an new kernel support.
+
+ The driver now requires a 2.6.12 (if pre-release, 2.6.12-rc1) or later
+ kernel.
+
+ Please heed these dependencies....
+
+
+ ********************************************************************
+
+
+The following information is provided for additional background on the
+history of the driver as we push for upstream acceptance.
+
+Cable pull and temporary device Loss:
+
+ In older revisions of the lpfc driver, the driver internally queued i/o
+ received from the midlayer. In the cases where a cable was pulled, link
+ jitter, or a device temporarily loses connectivity (due to its cable
+ being removed, a switch rebooting, or a device reboot), the driver could
+ hide the disappearance of the device from the midlayer. I/O's issued to
+ the LLDD would simply be queued for a short duration, allowing the device
+ to reappear or link come back alive, with no inadvertant side effects
+ to the system. If the driver did not hide these conditions, i/o would be
+ errored by the driver, the mid-layer would exhaust its retries, and the
+ device would be taken offline. Manual intervention would be required to
+ re-enable the device.
+
+ The community supporting kernel.org has driven an effort to remove
+ internal queuing from all LLDDs. The philosophy is that internal
+ queuing is unnecessary as the block layer already performs the
+ queuing. Removing the queues from the LLDD makes a more predictable
+ and more simple LLDD.
+
+ As a potential new addition to kernel.org, the 8.x driver was asked to
+ have all internal queuing removed. Emulex complied with this request.
+ In explaining the impacts of this change, Emulex has worked with the
+ community in modifying the behavior of the SCSI midlayer so that SCSI
+ devices can be temporarily suspended while transport events (such as
+ those described) can occur.
+
+ The proposed patch was posted to the linux-scsi mailing list. The patch
+ is contained in the 2.6.10-rc2 (and later) patch kits. As such, this
+ patch is part of the standard 2.6.10 kernel.
+
+ By default, the driver expects the patches for block/unblock interfaces
+ to be present in the kernel. No #define needs to be set to enable support.
+
+
+Kernel Support
+
+ This source package is targeted for the upstream kernel only. (See notes
+ at the top of this file). It relies on interfaces that are slowing
+ migrating into the kernel.org kernel.
+
+ At this time, the driver requires the 2.6.12 (if pre-release, 2.6.12-rc1)
+ kernel.
+
+ If a driver is needed for older kernels please utilize the 8.0.16
+ driver sources.
+
+
+Patches
+
+ Thankfully, at this time, patches are not needed.
