-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 received 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 accommodate 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 initialized. 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 losing 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 unnecessary 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 its 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 than 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 accommodate 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 empty 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 unused 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 occurrences 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

- * 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
-

- 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

- 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: separate nodev_tmo and els_retry_delay into 2
- separate 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.

- 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.

- 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.

- * 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.

- 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.

- * Fixed insmod hang after hardware error.
- * Relocated scsi_host alloc to before we enable the interrupt
- handler

- 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

-
- * 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.

- * 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.

- 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

- * 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.

- 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(),

- 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().

- 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.

- * 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

- 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

- - 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.

- 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.

- * 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 parallelly.
- * 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.
