|  | 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 | 
|  | * 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: 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. | 
|  | * Changed CLASS_PARMS to struct class_parms. | 
|  | * Some cosmetic coding style cleanups to lpfc_fcp.c. | 
|  | * Providing a sysfs interface that dumps the last 32 | 
|  | 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. | 
|  | * Changed FCP_CMND to struct fcp_cmnd. | 
|  | * Changed FCP_RSP to struct fcp_rsp. | 
|  | * Remove the need for buf_tmo. | 
|  | * Changed ULP_BDE64 to struct ulp_bde64. | 
|  | * Changed ULP_BDE to struct ulp_bde. | 
|  | * Cleanup lpfc_os_return_scsi_cmd() and its call path. | 
|  | * Removed lpfc_no_device_delay. | 
|  | * Consolidating lpfc_hba_put_event() into lpfc_put_event(). | 
|  | * Removed following attributes and their functionality: | 
|  | lpfc_extra_io_tmo, lpfc_nodev_holdio, lpfc_delay_rsp_err, | 
|  | lpfc_tgt_queue_depth and lpfc_check_cond_err. | 
|  | * Clock changes consolidating timers, just in the struct lpfc_hba, | 
|  | to get rid of clkData and pass only one argument to timeout | 
|  | routine. Also, removing need for outstanding clock linked list | 
|  | to stop these timers at rmmod. | 
|  | * Move lpfc.conf contents into lpfc_fcp.c. Removing per adapter | 
|  | attributes in favor of global attributes. | 
|  | * Fix a potential null pointer reference of pmbuf in lpfc_ct.c. | 
|  | * On reset_lun, issue LUN_RESET as opposed to ABORT_TASK_SET. | 
|  | * Removed SCSI_REQ_TMO related code. | 
|  | * Introducing two new defines LPFC_ATTR_R and LPFC_ATTR_RW that do | 
|  | a module_param, MODULE_PARM_DESC, lpfc_param_show, | 
|  | [lpfc_param_store] and CLASS_DEVICE_ATTRIBUTE. | 
|  | * Properly clean up when allocation of a linked BDE fails in the | 
|  | SCSI queuecommand path. | 
|  | * Fail SCSI command if dma_map_sg call fails. | 
|  | * Remove unused macros SWAP_ALWAYS and SWAP_ALWAYS16. | 
|  | * Reset context2 to 0 on exit in | 
|  | lpfc_sli_issue_iocb_wait_high_priority() and | 
|  | lpfc_sli_issue_iocb_wait(). | 
|  | * Arranging lpfc_scsiport.c to follow style of use after | 
|  | definition. This removes the need for the cruft of forward | 
|  | declarations. Also removing a redundant #define ScsiResult as it | 
|  | already available elsewhere. | 
|  | * Applying "Streamline lpfc error handling" patch from Christoph | 
|  | Hellwig (hch@infradead.org) with following modifications: fix | 
|  | mem leaks, remove some misplaced code that need not be there, | 
|  | print a message on exit (old code prints two (entry/exit)), make | 
|  | ret values consistent (either 1/0 or SUCCESS/FAILURE), keep all | 
|  | eh routines in a single file (lpfc_scsiport.c). | 
|  | * Move contents of lpfc_module_param.h into lpfc_fcp.c. | 
|  | * Changed sysfs attributes to CLASS_DEVICE_ATTRIBUTES (previously | 
|  | DEVICE_ATTRIBUTES). They now appear in | 
|  | /sys/class/scsi_host/hostx (previously in | 
|  | /sys/bus/pci/drivers/lpfc/devx). | 
|  | * Removed lpfc_syfs.h and lpfc_sysfs.c. | 
|  | * Cleanup of config params.  Throttle params have been removed. | 
|  | max_lun has been removed. max_target is replaced with a #define, | 
|  | lun_skip is removed.  Remove ipfc config params and related | 
|  | code. | 
|  | * Changed DMABUF_t usage to struct lpfc_dmabuf. | 
|  | * Downsizing iCfgParam structure to include a_string, a_low, a_hi | 
|  | and a_default values only. | 
|  | * Free SCSI buf safety memory pool on shutdown to eliminate memory | 
|  | leak. | 
|  | * Change lpfc_printf_log to a #define. Also include phba->brd_no | 
|  | and newline in the print string rather than in the #define. | 
|  | * Remove code that optionally locates Host Group Pointers in host | 
|  | memory SLIM since this is no longer needed for PPC64, once | 
|  | CONFIG_PORT uses HBA's view of its BAR0. | 
|  | * Removed the forward declarations of the sli functions and | 
|  | rearranging the code in lpfc_sli.c. | 
|  | * Removed the preamble functionality from logging. | 
|  | * Make lpfc_sli_hba_setup() return negative error codes on error | 
|  | and correct the comment left over in lpfc_fcp.c | 
|  | * Removed the lpfc_loadtime variable. | 
|  | * Put a space between all ifs and their open parens '('. | 
|  | * Change Studly_Caps LPFC_SCSI_BUF_t to struct lpfc_scsi_buf. | 
|  | * Fixed insmod hang after hardware error. | 
|  | * Relocated scsi_host alloc to before we enable the interrupt | 
|  | handler | 
|  | * Add .tmp_versions directory to Makefile clean target.  This | 
|  | directory is created in the 2.6.5+ build process (with Red Hat | 
|  | kernels at least). | 
|  | * Changing phba->config to kmalloc lpfc_icfgparam and not | 
|  | *phba->config. This is manifesting itself as a panic in | 
|  | pci_release_region(). | 
|  | * Fix for firmware download / board reset problem. | 
|  | * Integrated patch from Christoph Hellwig (hch@infradead.org) to | 
|  | reorganize and cleanup lpfc_fcp.c | 
|  | * Don't abort commands immediately when there is an RSCN event to | 
|  | give driver time to rediscover targets before the midlayer | 
|  | retries the SCSI commands. | 
|  |  | 
|  | Changes from 20040604 to 20040614 | 
|  |  | 
|  | * Changed version number to 8.0.4 | 
|  | * Removed lpfc_valid_lun function. | 
|  | * Added scsi_buf safety pool to address scsi_buf failures in | 
|  | queuecommand under low memory conditions.  Allocations now come | 
|  | from kmalloc initially, but if kmalloc fails, the allocation | 
|  | comes from the safety pool. | 
|  | * Modified lpfc_slave_alloc to only set the scsi_device->hostdata | 
|  | pointer if the driver has discovered the target.  This routine | 
|  | always returns success now as well since no error ever occurs in | 
|  | the alloc routine. | 
|  | * Mask only info and warning messages.  Print all error messages | 
|  | irrespective of mask. | 
|  | * Removing lpfc_log_chk_msg_disabled() | 
|  | * Changed lpfc_printf_log to take struct lpfc_hba * directly | 
|  | instead of a "board number". | 
|  | * Convert dma_sync_single to pci_dma_sync_single_for_{device/cpu}. | 
|  | * Implemented new style log messages. The message strings are now | 
|  | embedded in the call to lpfc_printf_log. | 
|  | * Decreased FLOGI discovery timeout to 20 seconds. | 
|  | * On error in lpfc_pci_probe_one() return -1 and not 1. | 
|  | * Allow for board numbers that are not sequential, paving the way | 
|  | for hotplug support. | 
|  | * scsi_add_host() can fail, so wrap it around in an if(). Also | 
|  | initiate scsi_scan_host() after attaching the sysfs attributes. | 
|  | * lpfc_release_version is used only in lpfc_ct.c, so move it there | 
|  | and mark it as static. | 
|  | * Removed lpfc_sleep_ms and replaced with mdelay or schedule calls | 
|  | directly | 
|  | * Removed all (struct list_head *) casts from clkData-related list | 
|  | handling in list_add, list_del macros. | 
|  | * Removed EXPORT_SYMBOLs. | 
|  | * Removed LPFC_MIN_QFULL and lpfc_qthrottle_up. | 
|  | * Replace LPFCSCSITARGET_t with struct lpfc_target. | 
|  | * Replace LPFCSCSILUN_t with struct lpfc_lun. | 
|  | * Remove unused struct declarations (fcPathId and fcRouteId) from | 
|  | lpfc_scsi.h. | 
|  | * Rewrite use of FC transport attributes. | 
|  | * Fix crash when link is lost.  This was due to lpfc_delay_iodone | 
|  | calling list_del on an object that was never put on a list. | 
|  | * Remove trailing spaces at the end of all lines. | 
|  | * Set MAX_FCP_TARGET to 256 from 0xff.  Set MAX_FCP_LUN and | 
|  | MAX_FCP_CMDS to their decimal equivalents and updated | 
|  | documentation. | 
|  |  | 
|  | Changes from 20040526 to 20040604 | 
|  |  | 
|  | * Changed version number to 8.0.3 | 
|  | * Completed sysfs FC transport support. | 
|  | * Removed unused fields in SCSI LUN and SCSI Target structures: | 
|  | void *pTargetProto; void *pTargetOSEnv; void *pLunOSEnv; | 
|  | * Modified list_for_each to list_for_each_entry. Modified | 
|  | list_for_each_safe to list_for_each_entry_safe. | 
|  | * Remove lpfc_dfc.h file. | 
|  | * Changed pHba->phba, pCommand->pcmd | 
|  | * Changed plogi_ndlp -> plogindlp, pos_tmp->postmp, pRsp->prsp, | 
|  | pCmd->pcmd | 
|  | * Changed pText -> ptext | 
|  | * Changed p_tmp_buff -> ptmpbuff | 
|  | * Changed pBufList -> pbuflist, pRsp -> prsp, pCmd -> pcmd | 
|  | * Changed *pos_tmp -> *postmp, *p_mbuf -> *pmbuf | 
|  | * Following changes are made to the SCSI fast path: Added | 
|  | DMA_BUF_t member to the lpfc_scsi_buf_t.  This will reduce a | 
|  | memory allocation in the scsi fast path.  Added check for | 
|  | targetp == NULL in the scsi fast path.  Increased number of | 
|  | scatter gather entries in lpfc_scsi_dma_ext to 4 from 3 and | 
|  | changed the size of lpfc_scsi_dma_ext to 264 | 
|  | * Fixing some missing static lpfc_nportdisc.c. | 
|  | * Reordered #include lines so that lpfc.h doesn't have to #include | 
|  | other header files. | 
|  | * Remove lpfc_get_hba_sym_node_name() as a global EXPORT and make | 
|  | it static. | 
|  | * Move struct clk_data definition from lpfc_hw.h to lpfc_sli.h. | 
|  | * Changed LPFC_IOCBQ_t to struct lpfc_iocbq. | 
|  | * Changed LPFC_SLI_RING_t to struct lpfc_sli_ring. | 
|  | * Changed LPFC_NODELIST_t to struct lpfc_nodelist. | 
|  | * Rearranged lpfc_nportdisc.c by moving state machine array | 
|  | (lpfc_disc_action) and the one function that uses it, | 
|  | lpfc_disc_state_machine, to the end of the file, removing the | 
|  | need for the raft of prototypes at the top. | 
|  | * Changed LPFC_BINDLIST_t to struct lpfc_bindlist. | 
|  | * Removed lpfc_issue_ct_rsp(), lpfc_sleep(), lpfc_add_bind(), | 
|  | lpfc_del_bind(), lpfc_sli_wake_mbox_wait() and | 
|  | lpfc_sli_issue_mbox_wait(). | 
|  | * Fixed a large number of overly-long lines. | 
|  | * Fixed some discovery problems: Introduced deferred ndlp removal | 
|  | when in DSM to avoid panic when in nested DMSs Fix NportId | 
|  | fffc01 handling to not relogin after LOGO fixed handling of LOGO | 
|  | on PLOGI issue. | 
|  | * Changed SLI_CT_REQUEST to lpfc_sli_ct_request. | 
|  | * Changed NAME_TYPE to struct lpfc_name. | 
|  | * Changed lpfcCfgParam_t to struct lpfc_cfgparam. | 
|  | * Changed LPFC_STAT_t to struct lpfc_stats. | 
|  | * Changed HBAEVT_t to struct lpfc_hba_event. | 
|  | * Changed Studly_Caps lpfcHBA_t to struct lpfc_hba. | 
|  | * Removed no longer used tasklet_running flag. | 
|  | * Removing *PSOME_VAR typedefs and using SOME_VAR* directly. | 
|  | * Changing .use_clustering to ENABLE_CLUSTERING. | 
|  | * Modify lpfc_queuecommand to return SCSI_MLQUEUE_HOST_BUSY when | 
|  | it can't queue a SCSI command.  Also, remove cmnds_in_flight | 
|  | member of struct lpfcHBA for 2.6 kernels as it was only needed | 
|  | to determine what to return from queuecommand. | 
|  | * Change return type of lpfc_evt_iocb_free to void as it doesn't | 
|  | return anything. | 
|  | * Remove unused cmnd_retry_list and in_retry members in struct | 
|  | lpfcHBA. | 
|  | * Remove some instances of unneeded casting of kmalloc's return in | 
|  | lpfc_scsiport.c | 
|  | * Remove lpfc_linux_attach() and lpfc_linux_detach(). Integrate | 
|  | them into lpfc_probe_one() and lpfc_release_one() respectively. | 
|  | * Remove lpfc_num_iocbs, lpfc_num_bufs module parameters | 
|  | * Remove #defines for NUM_NODES, NUM_BUFS and NUM_IOCBS | 
|  |  | 
|  | Changes from 20040515 to 20040526 | 
|  |  | 
|  | * Changing version number to 8.0.2. | 
|  | * Including dma-mapping.h as one of the include headers.  Also | 
|  | rearrange the #include order. | 
|  | * Make functions static as appropriate. | 
|  | * queuecommand() will now return SCSI_MLQUEUE_HOST_BUSY instead of | 
|  | 1 to backpressure midlayer. | 
|  | * Removed function prototypes for lpfc_start_timer() and | 
|  | lpfc_stop_timer() | 
|  | * Changed timer support to be inline.  Clk_data is now declared | 
|  | right next to the corresponding timer_list entry so we don't | 
|  | have to allocate these clk_data dynamically. | 
|  | * Add readls after writels to PCI space to flush the writes. | 
|  | * Fix misspelled word "safety" in function names. | 
|  | * Fix up comments in lpfc.conf for per HBA parameters to reflect | 
|  | new implementation. | 
|  | * Change lpfc_proc_info handler to get the Nodename from | 
|  | fc_nodename and not fc_portname. | 
|  | * Fix up some comments and whitespace in lpfc_fcp.c. | 
|  | * Formatting changes: get rid of leading spaces in code | 
|  | * Move discovery processing from tasklet to a kernel thread. | 
|  | * Move ndlp node from unmap list to map list if ADISC completed | 
|  | successfully. | 
|  | * Flush all the ELS IOCBs when there is a link event. | 
|  | * LP9802 qdepth is twice the LP9802DC qdepth.  Delay | 
|  | elx_sched_init after READ_CONFIG to get max_xri from the | 
|  | firmware.  Reset ELX_CFG_DFT_HBA_Q_DEPTH to max_xri after | 
|  | READ_CONFIG | 
|  | * Fix fc_get_cfg_parm() to be more robust and support embedded hex | 
|  | values.  The lpfc_param's are now defined as: | 
|  | lpfc_log_verbose="lpfc:0,lpfc0:0x10,lpfc1:4,lpfc100:0xffff" The | 
|  | "," delimter does not matter. It can be anything or not exist at | 
|  | all. ie param = "lpfc:0lpfc0:0x10.lpfc1:4txtlpfc100:0xffff" will | 
|  | also work.  Additionally the string is treated as case | 
|  | insensitive. | 
|  | * Changed all usage of lpfc_find_lun_device() to lpfc_find_lun(). | 
|  | * Removed unnecessary wrappers lpfc_find_lun_device() and | 
|  | lpfc_tran_find_lun(). | 
|  | * Switch from using internal bus/id/lun to similar data from | 
|  | scsi_device structure. | 
|  | * Eliminate one-line function lpfc_find_target() | 
|  | * Added slave_alloc, slave_destory | 
|  | * lpfc_scsi_cmd_start can now acquire lun pointer from | 
|  | scsi_device->hostdata, which is setup in slave_alloc. | 
|  | * Eliminate unnecessary checking on every cmd just to see if we | 
|  | are accessing the device the first time. | 
|  | * Remove assumption in lpfc_reset_lun_handler that a valid | 
|  | lpfc_scsi_buf is hung off of linux's scsi_cmnd->host_scribble | 
|  | when our reset is called. | 
|  |  | 
|  | Changes from 20040507 to 20040515 | 
|  |  | 
|  | * Changed version to 8.0.1 | 
|  | * Fixed crash on driver rmmod after error injection tests and | 
|  | lpfc_tasklet deadlock. | 
|  | * Modified lpfc.conf to remove limit on number of support hosts | 
|  | * Removed HBAAPI | 
|  | * Removed duplication of SCSI opcodes from lpfc_fcp.h that are | 
|  | available in scsi/scsi.h | 
|  | * Rework module_param usage | 
|  | * Added MODULE_PARAM_DESC for various module_params | 
|  | * Removed #define EXPORT_SYMTAB | 
|  | * Removed #includes of if_arp.h and rtnetlink.h | 
|  | * Removed string "Open Source" from MODULE_DESC | 
|  | * Cleanup duplicated string definitions used by MODULE_DESC | 
|  | * Renamed lpfc_pci_[detect|release] to lpfc_pci_[probe|remove]_one | 
|  | * Fix formatting of lpfc_driver | 
|  | * Remove unnecessary memset to 0 of lpfcDRVR | 
|  | * Attach driver attributes always unless pci_module_init failed | 
|  | * Remove all one-line wrappers from lpfc_mem. | 
|  | * Remove lpfc_sysfs_set_[show|store] as it is no longer needed | 
|  | * Redo lpfc_sysfs_params_[show|store] to one value per attribute rule | 
|  | * Breakdown lpfc_sysfs_info_show into smaller one value per attribute | 
|  | * Use device attributes instead of driver attributes where appropriate | 
|  | * Remove no longer needed EXPORT_SYMBOLs | 
|  | * Remove some unused code (1600 msg's related) | 
|  |  | 
|  | Changes from 20040429 to 20040507 | 
|  |  | 
|  | * Change version to 8.0.0 | 
|  | * Fix the number of cmd / rsp ring entries in lpfc_fcp.c to match | 
|  | the divisions setup in lpfc_hw.h. | 
|  | * Remove phba->iflag reference. | 
|  | * Several locking improvements. | 
|  | * Remove functions lpfc_drvr_init_lock, lpfc_drvr_lock, | 
|  | lpfc_drvr_unlock and lpfc_hipri_*. | 
|  | * Remove LPFC_DRVR_LOCK and LPFC_DRVR_UNLOCK macros. | 
|  | * Make lpfc_info() use lpfc_get_hba_model_desc() instead of | 
|  | rewriting almost identical code. | 
|  | * Fix 1 overly long line in each of lpfc_cfgparm.h, lpfc_ftp.c and | 
|  | lpfc_sli.c. | 
|  | * Fix build for Red Hat 2.6.3 kernel by #defining MODULE_VERSION | 
|  | only if it isn't already defined. | 
|  | * Change elx_sli_issue_mbox_wait to return correct error code to | 
|  | the caller. | 
|  | * In some of the els completion routines, after calling | 
|  | lpfc_elx_chk_latt, driver ignores the return code of the | 
|  | lpfc_elx_chk_latt. This will prevent the discovery state machine | 
|  | restarting correctly when there are link events in the middle of | 
|  | discovery state machine running. Fix this by exiting discovery | 
|  | state machine if lpfc_els_chk_latt returns a non zero value. | 
|  | * Removed MAX_LPFC_BRDS from lpfc_diag.h | 
|  | * Removed unused first_check. | 
|  | * Remove some unused fields and defines. | 
|  | * Change lpfc-param names to lpfc_param. | 
|  | * Add use of MODULE_VERSION macro for 2.6 kernels. | 
|  | * Shorten length of some of the comment lines to make them more | 
|  | readable. | 
|  | * Move FCP_* definitions to their own header file, lpfc_fcp.h. | 
|  | * Remove unused prototypes from lpfc_crtn.h: fcptst, iptst, | 
|  | lpfc_DELAYMS. | 
|  | * Remove duplicated prototypes from lpfc_crtn.h: | 
|  | lpfc_config_port_prep, lpfc_config_port_post, | 
|  | lpfc_hba_down_prep. | 
|  | * Removed some unused export_symbols. | 
|  | * Install driver files into */drivers/scsi/lpfc instead of | 
|  | */drivers/scsi. | 
|  |  | 
|  | Changes from 20040426 to 20040429 | 
|  |  | 
|  | * Declared export symbol lpfc_page_alloc and lpfc_page_free | 
|  | * Changed lpfc version number to 6.98.3 | 
|  | * Move the definition of MAX_LPFC_BRDS to the only header file | 
|  | that uses it (lpfc_diag.h). | 
|  | * Change lpfc_sli_wake_iocb_wait to do a regular wake_up since | 
|  | lpfc_sli_issue_iocb_wait now sleeps uninterruptible. | 
|  | * Replace list_for_each() with list_for_each_safe() when a list | 
|  | element could be deleted. | 
|  | * Fix IOCB memory leak | 
|  |  | 
|  | Changes from 20040416 to 20040426 | 
|  |  | 
|  | * Change lpfc_config_port_prep() to interpret word 4 of the DUMP | 
|  | mbox response as a byte-count | 
|  | * Add info attribute to sysfs | 
|  | * Minor formatting (spaces to tabs) cleanup in lpfc_sched.h | 
|  | * Remove unused log message number 732 | 
|  | * Completing MODULE_PARM -> module_param changes | 
|  | * Removed unused targetenable module parameter | 
|  | * Removed locks from lpfc_sli_issue_mbox_wait routine | 
|  | * Removed code that retry 29,00 check condition | 
|  | * Removed code that manipulates rspSnsLen. | 
|  | * Fix use of lun-q-depth config param | 
|  | * Fix severity inconsistency with log message 249 | 
|  | * Removed lpfc_max_target from lpfc_linux_attach | 
|  | * Replace references to lpfcDRVR.pHba[] with lpfc_get_phba_by_inst() | 
|  | * Change lpfc_param to lpfc-param | 
|  | * Partially removed 32 HBA restriction within driver.  Incorported | 
|  | lpfc_instcnt, lpfc_instance[], and pHba[] into lpfcDRVR | 
|  | structure Added routines lpfc_get_phba_by_inst() | 
|  | lpfc_get_inst_by_phba() lpfc_check_valid_phba() | 
|  | * Turn on attributes "set" & "params" by default. | 
|  | * Further formatting/whitespace/line length cleanup on: lpfc_ct.c | 
|  | lpfc_els.c lpfc_fcp.c lpfc_hbadisc.c lpfc_init.c lpfc_ipport.c | 
|  | lpfc_mbox.c lpfc_nportdisc.c lpfc_sched.c lpfc_sched.h | 
|  | lpfc_scsi.h lpfc_scsiport.c lpfc_sli.c and lpfc_sli.h | 
|  | * Add log message 249 to log any unsupported device addressing | 
|  | modes encountered. | 
|  | * Add support for 256 targets and 256 LUNs | 
|  | * Fixed panic in lpfc_linkdown. | 
|  | * Removed (struct list_head*) casting in several calls to list_del | 
|  | * Free irq reservation and kill running timers when insmod or | 
|  | modprobe are killed via ctrl-c | 
|  | * Remove drivers/scsi from include path | 
|  | * Wrap use of log message 311 in macro | 
|  | * Detect failure return from pci_map_sg call in lpfc_os_prep_io | 
|  | * Fix use-after-free of IOCB in lpfc_sli_process_sol_iocb which | 
|  | was causing an Oops on 2.6.5 kernel. | 
|  | * Cleanup use of several gotos not used for error exit. | 
|  | * Replace memcpy_toio() and memcpy_toio() with endian-dependent | 
|  | lpfc_memcpy_to_slim() and lpfc_memcpy_from_slim() so that for | 
|  | big endian hosts like PPC64, the SLIM is accessed 4 bytes at a | 
|  | time instead of as a byte-stream. | 
|  |  | 
|  | Changes from 20040409 to 20040416 | 
|  |  | 
|  | * The scsi_register and scsi_alloc_host OS calls can fail and | 
|  | return a zero-valued host pointer.  A ctrl-C on 2.6 kernels | 
|  | during driver load will cause this and the driver to panic. | 
|  | Fixed this bug.  Also found a bug in the error_x handling with | 
|  | lpfc_sli_hba_down - it was in the wrong place and the driver | 
|  | lock was not held, but needed to be (in lpfc_linux_attach) Fixed | 
|  | both.  Did some minor comment clean up. | 
|  | * Removed unwanted (void *) castings. | 
|  | * Replace define of INVALID_PHYS, with kernel 2.6.5's | 
|  | dma_mapping_error() and add a inline function for earlier | 
|  | kernels.  Remove lpfc_bad_scatterlist(). | 
|  | * Clean up formatting in hbaapi.h, lpfc.h, lpfc_cfgparm.h, | 
|  | lpfc_crtn.h, lpfc_ct.c, lpfc_diag.h, lpfc_disc.h, lpfc_els.c, | 
|  | lpfc_fcp.c, lpfc_hbadisc.c, lpfc_hw.h, lpfc_init.c, | 
|  | lpfc_ipport.c, lpfc_logmsg.c, lpfc_logmsg.h and lpfc_scsiport.c | 
|  | - mostly replacing groups of 8 spaces with hard tabs and keeping | 
|  | lines to 80 column max.. | 
|  | * Removed LPFC_DRVR_LOCK call from lpfc_unblock_requests for 2.4 | 
|  | kernels.  The lpfc_scsi_done routine already unlocks the driver | 
|  | lock since it expects this lock to be held. | 
|  | * Removed global lock capabilities from driver lock routines | 
|  | * Remove SA_INTERRUPT flag from request_irq | 
|  | * Move dma_addr_t cast inside of getPaddr macro as everywhere | 
|  | getPaddr is used, the return is cast to dma_addr_t. | 
|  | * Clean up formatting in lpfc_sli.c and lpfc_sysfs.c - mostly | 
|  | replacing groups of 8 spaces with hard tabs and keeping lines | 
|  | to 80 column max. | 
|  | * Fix build for RHEL 2.1 BOOT kernels by always #including | 
|  | interrupt.h in lpfc.h. | 
|  | * Fix RHEL 3 build by #defining EXPORT_SYMTAB. | 
|  | * Replace sprintf with snprintf in lpfc_proc_info. | 
|  | * Fix build warnings on 2.6 kernels - remove no longer used calls | 
|  | to  character device initialization. | 
|  | * Initial support code for discovery in tasklet conversion. | 
|  | * Removing char interface and ioctl code. | 
|  | * Change all elx prefixes to lpfc | 
|  | * Replace lpfc_write_slim() & lpfc_read_slim() with memcpy_toio(), | 
|  | memcpy_fromio(), writel() & readl(). | 
|  |  | 
|  | Changes from 20040402 to 20040409 | 
|  |  | 
|  | * Replaced lpfc_read_hbaregs_plus_offset and | 
|  | lpfc_write_hbaregs_plus_offset functions with readl and writel. | 
|  | * Get rid of long mdelay's in insmod path | 
|  | * Changed the way our pci_device_id structures are initialized | 
|  | * Replace lpfc_read/write_CA/HA/HC/HS with calls to readl() & | 
|  | writel() directly. | 
|  | * Increase SLI2_SLIM to 16K Increase cmd / rsp IOCBs accordingly | 
|  | * Removed lpfc_els_chk_latt from the lpfc_config_post function. | 
|  | lpfc_els_chk_latt will enable the link event interrupts when | 
|  | flogi is pending which causes two discovery state machines | 
|  | running 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. | 
|  | * Change sleep to uninterruptible in lpfc_sli_issue_icob_wait | 
|  | because this function doesn't handle signals. | 
|  | * Move lpfc_wakeup_event from lpfc_fcp.c to lpfc_ioctl.c | 
|  | * Remove unneeded #include <linux/netdevice.h> | 
|  | * Remove unused clock variables lpfc_clkCnt and lpfc_sec_clk. | 
|  | * Get rid of capitalization of function names. | 
|  | * Removed lpfc_addr_sprintf. | 
|  | * Implemented gotos in lpfc_linux_attach for error cases. | 
|  | * Replace mlist->dma.list = dmp->dma.list; to mlist = dmp. | 
|  | * Remove functions lpfc_get_OsNameVersion and elx_wakeup. Change | 
|  | elx_wakeup to wake_up_interruptible | 
|  | * Add function lpfc_get_os_nameversion and change | 
|  | lpfc_get_OsNameVersion to lpfc_get_os_nameversion. | 
|  | * Remove lpfc_get_OsNameVersion | 
|  | * Change driver name to a consistent lpfc in every visible place. | 
|  | * Fix build warning: removed unused variable ret in lpfc_fdmi_tmo. | 
|  | * Remove lpfc_utsname_nodename_check function | 
|  | * Remove functions lpfc_register_intr and lpfc_unregister_intr | 
|  | * Fill in owner field in lpfc_ops file_operations struct and | 
|  | remove now unnecessary open and close entry points. | 
|  | * Change function name prefixes from elx_ to lpfc_ | 
|  | * Remove special case check for TUR in elx_os_prep_io() | 
|  | * Renamed elx_scsi.h to lpfc_scsi.h | 
|  | * Renamed elx_sched.h to lpfc_sched.h | 
|  | * Renamed elx_mem.h to lpfc_mem.h | 
|  | * Renamed elx_sli.h to lpfc_sli.h | 
|  | * Renamed elx_logmsg.h to lpfc_logmsg.h | 
|  | * Renamed elx.h to lpfc.h | 
|  | * Renamed elx_sli.c to lpfc_sli.c | 
|  | * Renamed elx_sched.c to lpfc_sched.c | 
|  | * Renamed elx_mem.c to lpfc_mem.c | 
|  | * Renamed elx_logmsg.c to lpfc_logmsg.c | 
|  | * Renamed lpfcLINUXfcp.c lpfc_fcp.c | 
|  | * Renamed elx_clock.c to lpfc_clock.c | 
|  | * Reduce stack usage in lpfc_info(). | 
|  | * Move lpip_stats structure from lpfc_hba.h to lpfc_ip.h. | 
|  | * Move lpfc_stats and HBAEVT_t structures from lpfc_hba.h to | 
|  | lpfc.h | 
|  | * Remove lpfc_hba.h | 
|  | * Remove duplicate rc definitions from | 
|  | * Removed code which used next pointer to store mbox structure. | 
|  | * Cleaned up list iterations. | 
|  | * Removed non list manipulation of the next pointers. | 
|  | * Change list_del()/INIT_LIST_HEAD sequences to list_del_init() | 
|  | * In ELX_IOCBQ_t: Moved hipri_trigger field to iocb_flag. Combined | 
|  | hipri_wait_queue and rsp_iocb in union | 
|  | * Replaced casting from list_head with list_entry macro. | 
|  | * Added ct_ndlp_context field to the ELX_IOCBQ_t. | 
|  | * Do not use DMABUf_t list to store ndlp context | 
|  | * Return 0 from lpfc_process_iotcl_util() when ELX_INITBRDS | 
|  | succeeds. | 
|  | * remove elx_os_scsiport.h | 
|  | * Do not use DMABUf_t list to hold rpi context | 
|  | * Replace elx_cfg_* names with lpfc_cfg-* | 
|  | * Moved FCP activity to ring 0.  Moved ELS/CT activity to ring 2. | 
|  | * Clean up formatting of elx_sli.h (tabs for indents, 80 column | 
|  | lines). | 
|  | * Remove unused elxclock declaration in elx_sli.h. | 
|  | * Since everywhere IOCB_ENTRY is used, the return value is cast, | 
|  | move the cast into the macro. | 
|  | * Split ioctls out into separate files | 
|  |  | 
|  | Changes from 20040326 to 20040402 | 
|  |  | 
|  | * Updated ChangeLog for 20040402 SourceForge drop. | 
|  | * Use safe list iterator for ndlp list | 
|  | * Added code to return NLP_STE_FREED_NODE from the discovery | 
|  | state machine functions if the node is freed from the | 
|  | function. | 
|  | * Fixes to DMABUF_t handling | 
|  | * Fix for load error in discovery | 
|  | * Remove loop_cnt variable from lpfc_rcv_plogi_unused_node. | 
|  | * Remove nle. reference. | 
|  | * Remove support for building 2.4 drivers | 
|  | * Remove elx_util.h and replace elx_disc.h with lpfc_disc.h | 
|  | * Implemented the Linux list macros in the discovery code. | 
|  | Also moved elx_disc.h contents into lpfc_disc.h | 
|  | * Unused variable cleanup | 
|  | * Use Linux list macros for DMABUF_t | 
|  | * Break up ioctls into 3 sections, dfc, util, hbaapi | 
|  | rearranged code so this could be easily separated into a | 
|  | differnet module later All 3 are currently turned on by | 
|  | defines in lpfc_ioctl.c LPFC_DFC_IOCTL, LPFC_UTIL_IOCTL, | 
|  | LPFC_HBAAPI_IOCTL | 
|  | * Misc cleanup: some goto's; add comments; clarify function | 
|  | args | 
|  | * Added code to use list macro for ELXSCSITARGET_t. | 
|  | * New list implementation for ELX_MBOXQ_t | 
|  | * Cleaned up some list_head casting. | 
|  | * Put IPFC ifdef around two members of struct lpfc_nodelist. | 
|  | * Cleaned up iocb list using list macros and list_head data | 
|  | structure. | 
|  | * lpfc_online() was missing some timer routines that were | 
|  | started by lpfc_linux_attach().  These routines are now also | 
|  | started by lpfc_online().  lpfc_offline() only stopped | 
|  | els_timeout routine.  It now stops all timeout routines | 
|  | associated with that hba. | 
|  | * Replace separate next and prev pointers in struct | 
|  | lpfc_bindlist with list_head type.  In elxHBA_t, replace | 
|  | fc_nlpbind_start and _end with fc_nlpbind_list and use | 
|  | list_head macros to access it. | 
|  | * Fix ulpStatus for aborting I/Os overlaps with newer firmware | 
|  | ulpStatus values | 
|  | * Rework params_show/store to be consistent as the other |

|  | * Remove unused log message. | 
|  | * Collapse elx_crtn.h and prod_crtn.h into lpfc_crtn.h | 
|  | * Ifdef Scheduler specific routines | 
|  | * Removed following ununsed ioclt's: ELX_READ_IOCB | 
|  | ELX_READ_MEMSEG ELX_READ_BINFO ELX_READ_EINVAL ELX_READ_LHBA | 
|  | ELX_READ_LXHBA ELX_SET ELX_DBG LPFC_TRACE | 
|  | * Removed variable fc_dbg_flg | 
|  | * Fixed a bug where HBA_Q_DEPTH was set incorrectly for | 
|  | 3-digit HBAs.  Also changed can_queue so midlayer will only | 
|  | send (HBA_Q_DEPTH - 10) cmds. | 
|  | * Clean up code in the error path, check condition.  Remove | 
|  | ununsed sense-related fields in lun structure. | 
|  | * Added code for safety pools for following objects: mbuf/bpl, | 
|  | mbox, iocb, ndlp, bind | 
|  | * Wrapped '#include <elx_sched.h>' in '#ifdef USE_SCHEDULER'. | 
|  | * Fixed 'make clean' target. | 
|  | * Build now ignores elx_sched.o, and includes lpfc_sysfs.o. | 
|  | * Wrapped lpfndd.o target in BUILD_IPFC ifdef. | 
|  | * Removed elx_os.h inclusion in implementation files. | 
|  | * Removed ELX_OS_IO_t data structure and put data direction | 
|  | and non scatter/gather physical address into the scsi buffer | 
|  | structure directly.  Moved DRVR_LOCK, putPaddr, getPaddr | 
|  | macros and some defines into elx.h since they are required | 
|  | by the whole driver. | 
|  | * Migrated following ioctls (debug) ELX_DISPLAY_PCI_ALL | 
|  | ELX_DEVP ELX_READ_BPLIST ELX_RESET_QDEPTH ELX_STAT. | 
|  | * Step 1 of attempt to move all Debug ioctls to sysfs. | 
|  | Implemented the following IOCTLs in sysfs: ELX_WRITE_HC | 
|  | ELX_WRITE_HS ELX_WRITE_HA ELX_WRITE_CA ELX_READ_HC | 
|  | ELX_READ_HS ELX_READ_HA ELX_READ_CA ELX_READ_MB ELX_RESET | 
|  | ELX_READ_HBA ELX_INSTANCE ELX_LIP.  Also introduced | 
|  | attribute "set" to be used in conjunction with the above | 
|  | attributes. | 
|  | * Removed DLINK, enque and deque declarations now that clock | 
|  | doesn't use them anymore | 
|  | * Separated install rule so that BUILD_IPFC has to be set when | 
|  | make is called in order for the install rule to attempt to | 
|  | copy the lpfndd.o driver.  This change fixes a bug that | 
|  | occurs because the install rule by default attempted to | 
|  | install lpfndd.o, whereas the default make rule did not by | 
|  | default build lpfndd.o. | 
|  | * Keep track if hbaapi index numbers need to be refreshed. | 
|  | * Removed prod_os.h from include list. | 
|  | * Removed LPFC_LOCK and LPFC_UNLOCK macros.  Added OS calls | 
|  | into elx_os_scsiport.c.  This file is now empty. | 
|  | * Added spin_lock_irqsave and spin_unlock_irqrestore calls | 
|  | into code directly and removed LPFC_LOCK_ and _UNLOCK_ | 
|  | macros | 
|  | * Remove references to "elx_clock.h" | 
|  | * Added utsname.h to include list.  The previous checkin to | 
|  | elx_os.h removed its inclusion of utsname.h since there is | 
|  | precious little in the file.  However, lpfcLINUXfcp.c needs | 
|  | it and now has it. | 
|  | * Removed some commented-out code | 
|  | * Removed elx_lck_t data structure, stray elxDRVR_t type, and | 
|  | include from file.  No longer used. | 
|  | * Removed two PCI Sync defines.  Removed includes - not | 
|  | needed.  Cleaned up macro lines. |

|  | were IPFC specific. | 
|  | * Removed hipri lock abstractions and added OS call into code. |

|  | IPFC functions into lpfc_ipport.c | 
|  | * Moved IP specific structures to lpfc_ip.h file. | 
|  | * lpfc_ipfarp_timeout() uses system timer.  Remove all usages | 
|  | of old internal clock support. | 
|  | * Made changes to compile without IPFC support for the default | 
|  | build.  Added ifdef IPFC for all lpfc_ip.h includes. | 
|  | * Patched elx_free_scsi_buf | 
|  | * Removed elx_sched.o from 2.6 dependencies | 
|  | * Reworked lpfc_pcimap. | 
|  | * Use Linux swap macros to replace ELX swapping macros | 
|  | (SWAP_SHORT, SWAP_LONG, SWAP_DATA, SWAP_DATA16, |

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

|  | * Minor formatting changes get rid of failover defines for | 
|  | syntax checking | 
|  | * Minor formatting changes remove ISCSI defines. |

|  | * Rewrite of Makefile. Fixes breakages with make -j4 during | 
|  | kernel compile. Does not recompile all files on every | 
|  | build. Uses the kernel build's definitions of CFLAGS, | 
|  | MODFLAGS etc. Removed "make rpm" option. |
