1Known issues :
2 * Please read the associated RELEASE-NOTES file !!!
3 * This source release intended for upstream kernel releases only!
4
5Changes from 20050323 to 20050413
6
7 * Changed version number to 8.0.28
8 * Fixed build warning for 2.6.12-rc2 kernels: mempool_alloc now
9 requires a function which takes an unsigned int for gfp_flags.
10 * Removed pci dma sync calls to coherent/consistent pci memory.
11 * Merged patch from Christoph Hellwig <hch@lst.de>: split helpers
12 for fabric and nport logins out of lpfc_cmpl_els_flogi.
13 * Removed sysfs attributes that are used to dump the various
14 discovery lists.
15 * Fix for issue where not all luns are seen. Search all lists
16 other than unmap list in lpfc_find_target(). Otherwise INQUIRY
17 to luns on nodes in NPR or other relevant states (PLOGI,
18 PRLI...) are errored back and scan() terminates.
19 * Removed FC_TRANSPORT_PATCHESxxx defines. They're in 2.6.12-rc1.
20 * Compare return value of lpfc_scsi_tgt_reset against SCSI
21 midlayer codes SUCCESS/FAILED which that function returns rather
22 than SLI return code.
23 * Removed extraneous calls to lpfc_sli_next_iotag which should
24 only be called from lpfc_sli_submit_iocb. Also make
25 lpfc_sli_next_iotag static.
26 * Added PCI ID for LP10000-S.
27 * Changes in lpfc_abort_handler(): Return SUCCESS if we did not
28 find command in both TX and TX completion queues. Return ERROR
29 if we timed out waiting for command to complete after abort was
30 issued.
31 * Zero-out response sense length in lpfc_scsi_prep_cmnd to prevent
32 interpretation of stale sense length when the command completes
33 - was causing spurious 0710 messages.
34 * Moved clearing of host_scribble inside host_lock in IO
35 completion path.
36 * Fixed a bunch of mixed tab/space indentation.
37 * Allow hex format numbers in sysfs attribute setting. Fix
38 application hang when invalid numbers are used in sysfs
39 settings.
40 * Removed extra iotag allocation by lpfc_abort_handler.
41 * Clear host_scribble in the scsi_cmnd structure when failing in
42 queuecommand.
43 * Changed logic at top of lpfc_abort_handler so that if the
44 command's host_scibble field is NULL, return SUCCESS because the
45 driver has already returned the command to the midlayer.
46
47Changes from 20050308 to 20050323
48
49 * Changed version number to 8.0.27
50 * Changed a few lines from patch submitted by Christoph Hellwig
51 (3/19). MAILBOX_WSIZE * (uint32_t) is replaced with an
52 equivalent MAILBOX_CMDSIZE macro.
53 * Merged patch from Christoph Hellwig (3/19): some misc patches
54 against the latest drivers:
55 - stop using volatile. if you need special ordering use memory
56 barriers but that doesn't seem to be the case here
57 - switch lpfc_sli_pcimem_bcopy to take void * arguments.
58 - remove typecast for constants - a U postfix marks them
59 unsigned int in C
60 - add a MAILBOX_CMD_SIZE macro, as most users of
61 MAILBOX_CMD_WSIZE didn't really want the word count
62 - kill struct lpfc_scsi_dma_buf and embedded the two members
63 directly in struct lpfc_scsi_buf
64 - don't call dma_sync function on allocations from
65 pci_pool_alloc - it's only for streaming mappings (pci_map_*)
66 * Merged patch from Christoph Hellwig (3/19) - nlp_failMask isn't
67 ever used by the driver, just reported to userspace (and that in
68 a multi-value file which is against the sysfs guidelines).
69 * Change pci_module_init to pci_register_module() with appropriate
70 ifdefs.
71 * Added #include <linux/dma-mapping.h> as required by the DMA
72 32bit and 64bit defines on some archs.
73 * Merged patch from Christoph Hellwig (03/19) - fix initialization
74 order - scsi_add_host must happen last from scsi POV. Also some
75 minor style/comment fixups.
76 * Fixed use of TRANSPORT_PATCHES_V2 by changing to
77 FC_TRANSPORT_PATCHES_V2.
78
79Changes from 20050223 to 20050308
80
81 * Changed version number to 8.0.26
82 * Revise TRANSPORT_PATCHES_V2 so that lpfc_target is removed and
83 rport data is used instead. Removed device_queue_hash[].
84 * Changed RW attributes of scan_down, max_luns and fcp_bind_method
85 to R only.
86 * Fixed RSCN handling during initial link initialization.
87 * Fixed issue with receiving PLOGI handling when node is on NPR
88 list and marked for ADISC.
89 * Fixed RSCN timeout issues.
90 * Reduced severity of "SCSI layer issued abort device" message to
91 KERN_WARNING.
92 * Feedback from Christoph Hellwig (on 2/5) - In the LPFC_EVT_SCAN
93 case the caller already has the target ID handly, so pass that
94 one in evt_arg1.
95 * Fix compile warning/resultant panic in
96 lpfc_register_remote_port().
97
98Changes from 20050215 to 20050223
99
100 * Changed version number to 8.0.25
101 * Add appropriate comments to lpfc_sli.c.
102 * Use DMA_64BIT_MASK and DMA_32BIT_MASK defines instead of
103 0xffffffffffffffffULL & 0xffffffffULL respectively. Use pci
104 equivalents instead of dma_set_mask and also modify condition
105 clause to actually exit on error condition.
106 * Restart els timeout handler only if txcmplq_cnt. On submission,
107 mod_timer the els_tmofunc. This prevents the worker thread from
108 waking up the els_tmo handler un-necessarily. The thread was
109 being woken up even when there were no pending els commands.
110 * Added new typedefs for abort and reset functions.
111 * Collapsed lpfc_sli_abort_iocb_xxx into a single function.
112 * Collapsed lpfc_sli_sum_iocb_xxx into a single function.
113 * Removed TXQ from all abort and reset handlers since it is never
114 used.
115 * Fixed Oops panic in 8.0.23 (reported on SourceForge). The
116 driver was not handling LPFC_IO_POLL cases correctly in
117 fast_ring_event and was setting the tgt_reset timeout to 0 in
118 lpfc_reset_bus_handler. This 0 timeout would not allow the FW
119 to timeout ABTS's on bad targets and allow the driver to have an
120 iocb on two lists. Also split the lpfc_sli_ringtxcmpl_get
121 function into two routines to match the fast and slow completion
122 semantics - ELS completions worked for the wrong reasons. Also
123 provided new log message number - had two 0326 entries.
124 * Removed unused #define LPFC_SCSI_INITIAL_BPL_SIZE.
125 * Removed unused struct lpfc_node_farp_pend definition.
126 * Removed unused #define LPFC_SLIM2_PAGE_AREA.
127 * Changed zeros used as pointers to NULL.
128 * Removed unneeded braces around single line in lpfc_do_work.
129 * Close humongous memory leak in lpfc_sli.c - driver was losing 13
130 iocbq structures per LIP.
131 * Removed last of GFP_ATOMIC allocations.
132 * Locks are not taken outside of nportdisc, hbadisc, els and most
133 of the init, sli, mbox and ct groups of functions
134 * Fix comment for lpfc_sli_iocb_cmd_type to fit within 80 columns.
135 * Replaced wait_event() with wait_event_interruptible().
136 wait_event() puts the woker thread in an UNINTERRUPTIBLE state
137 causing it to figure in load average calculations. Also add a
138 BUG_ON to the ret code of wait_event_interruptible() since the
139 premise is that the worker thread is signal-immune.
140
141Changes from 20050208 to 20050215
142
143 * Changed version number to 8.0.24
144 * Fixed a memory leak of iocbq structure. For ELS solicited iocbs
145 sli layer now frees the response iocbs after processing it.
146 * Closed large memory leak -- we were losing 13 iocbq structures
147 per LIP.
148 * Changing EIO and ENOMEM to -EIO and -ENOMEM respectively.
149 * Cleanup of lpfc_sli_iocb_cmd_type array and typing of iocb type.
150 * Implemented Christoph Hellwig's feedback from 02/05: Remove
151 macros putLunHigh, putLunLow. Use lpfc_put_lun() inline instead.
152 * Integrated Christoph Hellwig's feedback from 02/05: Instead of
153 cpu_to_be32(), use swab16((uint16_t)lun). This is the same as
154 "swab16() on LE" and "<<16 on BE".
155 * Added updates for revised FC remote port patch (dev_loss_tmo
156 moved to rport, hostdata renamed dd_data, add fc_remote_host()
157 on shutdown).
158 * Removed unnecessary function prototype.
159 * Added code to prevent waking up worker thread after the exit of
160 worker thread. Fixes panic seen with insmod/rmmod testing with
161 70 disks.
162 * Integrated Christoph Hellwig's patch from 1/30: Make some
163 variables/code static (namely lpfcAlpaArray and
164 process_nodev_timeout()).
165 * Integrated Christoph Hellwig's patch from 1/30: Use
166 switch...case instead of if...else if...else if while decoding
167 JDEC id.
168
169Changes from 20050201 to 20050208
170
171 * Changed version number to 8.0.23
172 * Make lpfc_work_done, lpfc_get_scsi_buf,
173 lpfc_mbx_process_link_up, lpfc_mbx_issue_link_down and
174 lpfc_sli_chipset_init static.
175 * Cleaned up references to list_head->next field in the driver.
176 * Replaced lpfc_discq_post_event with lpfc_workq_post_event.
177 * Implmented Christoph Hellwig's review from 2/5: Check for return
178 values of kmalloc.
179 * Integrated Christoph Hellwig's patch from 1/30: Protecting
180 scan_tmo and friends in !FC_TRANSPORT_PATCHES_V2 &&
181 !USE_SCAN_TARGET.
182 * Integrated Christoph Hellwig's patch from 1/30: Some fixes in
183 the evt handling area.
184 * Integrated Christoph Hellwig's patch from 1/30: Remove usage of
185 intr_inited variable. The interrupt initilization from OS side
186 now happens in lpfc_probe_one().
187 * Integrated Christoph Hellwig's patch from 1/30: remove shim
188 lpfc_alloc_transport_attr - remove shim lpfc_alloc_shost_attrs -
189 remove shim lpfc_scsi_host_init - allocate phba mem in scsi's
190 hostdata readjust code so that they are no use after free's
191 (don't use after scsi_host_put) - make lpfc_alloc_sysfs_attr
192 return errors
193 * Fixed panic in lpfc_probe_one(). Do not delete in a list
194 iterator that is not safe.
195 * Clean up fast lookup array of the fcp_ring when aborting iocbs.
196 * Following timeout handlers moved to the lpfc worker thread:
197 lpfc_disc_timeout, lpfc_els_timeout, lpfc_mbox, lpfc_fdmi_tmo,
198 lpfc_nodev_timeout, lpfc_els_retry_delay.
199 * Removed unused NLP_NS_NODE #define.
200 * Integrated Christoph Hellwig's patch from 1/30: remove unused
201 lpfc_hba_list; remove unused lpfc_rdrev_wd30; remove
202 lpfc_get_brd_no and use Linux provided IDR.
203 * Changed board reset procedure so that lpfc_sli_send_reset()
204 writes the INITFF bit and leaves lpfc_sli_brdreset() to clear
205 the bit.
206 * Removed outfcpio sysfs device attribute.
207 * VPD changes: 1) Modify driver to use the model name and
208 description from the VPD data if it exists 2) Rework use of DUMP
209 mailbox command to support HBAs with 256 bytes of SLIM.
210 * Fixed compile error for implicit definition of struct
211 scsi_target
212
213Changes from 20050124 to 20050201
214
215 * Changed version number to 8.0.22
216 * Moved discovery timeout handler to worker thread. There are
217 function calls in this function which are not safe to call from
218 HW interrupt context.
219 * Removed free_irq from the error path of HBA initialization.
220 This will fix the free of uninitialised IRQ when config_port
221 fails.
222 * Make sure function which processes unsolicited IOCBs on ELS ring
223 still is called with the lock held.
224 * Clear LA bit from work_ha when we are not supposed to handle LA.
225 * Fix double locking bug in the error handling part of
226 lpfc_mbx_cmpl_read_la.
227 * Implemented fast IOCB processing for FCP ring.
228 * Since mboxes are now unconditionally allocated outside of the
229 lock, free them in cases where they are not used.
230 * Moved out a couple of GFP_ATOMICs in lpfc_disc_timeout, to
231 before locks so that they can GFP_KERNEL instead. Also cleaned
232 up code.
233 * Collapsed interrupt handling code into one function.
234 * Removed event posting and handling of solicited and unsolicited
235 iocbs.
236 * Remove ELS ring handling leftovers from the lpfc_sli_inter().
237 * ELS ring (any slow ring) moved from the lpfc_sli_inter() into a
238 worker thread. Link Attention, Mbox Attention, and Error
239 Attention, as well as slow rings' attention is passed to the
240 worker thread via worker thread copy of Host Attention
241 register. Corresponding events are removed from the event queue
242 handling.
243 * Add entries to hba structure to delegate some functionality from
244 the lpfc_sli_inter() to a worker thread.
245 * Reduced used of GFP_ATOMIC for memory allocations.
246 * Moved locks deeper in order to change GFP_ATOMIC to GFP_KERNEL.
247 * IOCB initialization fix for Raw IO.
248 * Removed qcmdcnt, iodonecnt, errcnt from lpfc_target and from
249 driver.
250 * Added call to lpfc_els_abort in lpfc_free_node. Modified
251 lpfc_els_abort to reset txq and txcmplq iterator after a
252 iocb_cmpl call.
253 * Fixed a use after free issue in lpfc_init.c.
254 * Defined default mailbox completion routine and removed code in
255 the sli layer which checks the mbox_cmpl == 0 to free mail box
256 resources.
257 * In lpfc_workq_post_event, clean up comment formatting and remove
258 unneeded cast of kmalloc's return.
259 * Removed loop which calls fc_remote_port_unblock and
260 fc_remote_port_delete for every target as this same effect is
261 accomplished by the scsi_remove_host call.
262 * Minor cleanup of header files. Stop header files including
263 other header files. Removed sentinels which hide multiple
264 inclusions. Removed unneeded #include directives.
265 * Fixed memory leaks in mailbox error paths.
266 * Moved lock from around of lpfc_work_done to lpfc_work_done
267 itself.
268 * Removed typedef for LPFC_WORK_EVT_t and left just struct
269 lpfc_work_evt to comply with linux_scsi review coding style.
270 * Fixed some trailing whitespaces, spaces used for indentation and
271 ill-formatting multiline comments.
272 * Bug fix for Raw IO errors. Reuse of IOCBs now mandates setting
273 of ulpPU and fcpi_parm to avoid incorrect read check of Write IO
274 and incorrect read length.
275
276Changes from 20050110 to 20050124
277
278 * Changed version number to 8.0.21
279 * Removed unpleasant casting in the definition and use of
280 lpfc_disc_action function pointer array.
281 * Makefile cleanup. Use ?= operator for setting default
282 KERNELVERSION and BASEINCLUDE values. Use $(PWD) consistently.
283 * Removed call to lpfc_sli_intr from lpfc_config_port_post. All
284 Linux systems will service hardware interrupts while bringing up
285 the driver.
286 * Christoph Hellwig change request: Reorg of contents of
287 lpfc_hbadisc.c, lpfc_scsi.h, lpfc_init.c, lpfc_sli.c,
288 lpfc_attr.c, lpfc_scsi.c.
289 * Renamed discovery thread to lpfc_worker thread. Moved handling
290 of error attention and link attention and mbox event handler to
291 lpfc_worker thread.
292 * Removed .proc_info and .proc_name from the driver template and
293 associated code.
294 * Removed check of FC_UNLOADING flag in lpfc_queuecommand to
295 determine what result to return.
296 * Move modification of FC_UNLOADING flag under host_lock.
297 * Fix IOERR_RCV_BUFFER_WAITING handling for CT and ELS subsystem.
298 * Workaround firmware bug for IOERR_RCV_BUFFER_WAITING on ELS
299 ring.
300 * Fixed a couple lpfc_post_buffer problems in lpfc_init.c.
301 * Add missing spaces to the parameter descriptions for
302 lpfc_cr_delay, lpfc_cr_count and lpfc_discovery_threads.
303 * Lock before calling lpfc_sli_hba_down().
304 * Fix leak of "host" in the error path in the remove_one() path.
305 * Fix comment for lpfc_cr_count. It defaults to 1.
306 * Fix issue where we are calling lpfc_disc_done() recursively from
307 lpfc_linkdown(), but list_for_each_entry_safe() is not safe for
308 such use.
309 * Bump lpfc_discovery_threads (count of outstading ELS commands in
310 discovery) to 32
311 * If the SCSI midlayer tries to recover from an error on a lun
312 while the corresponding target is in the NPR state, lpfc driver
313 will reject all the resets. This will cause the target to be
314 moved to offline state and block all the I/Os. The fix for this
315 is to delay the lun reset to a target which is not in MAPPED
316 state until the target is rediscovered or nodev timeout is
317 fired.
318
319Changes from 20041229 to 20050110
320
321 * Changed version number to 8.0.20
322 * rport fix: use new fc_remote_port_rolechg() function instead of
323 direct structure change
324 * rport fix: last null pointer check
325 * Phase II of GFP_ATOMIC effort. Replaced iocb_mem_pool and
326 scsibuf_mem_pool with kmalloc and linked list. Inserted list
327 operations for mempool_alloc calls. General code cleanup. All
328 abort and reset routines converted. Handle_ring_event
329 converted.
330 * If the mbox_cmpl == lpfc_sli_wake_mbox_wait in
331 lpfc_sli_handle_mb_event, pmb->context1 points to a waitq. Do
332 not free the structure.
333 * rport fixes: fix for rmmod crash
334 * rport fixes: when receiving PRLI's, set node/rport role values
335 * rport fixes: fix for unload and for fabric port deletes
336 * VPD info bug fix.
337 * lpfc_linkdown() should be able to process all outstanding events
338 by calling lpfc_disc_done() even if it is called from
339 lpfc_disc_done() Moving all events from phba->dpc_disc to local
340 local_dpc_disc prevents those events from being processed.
341 Removing that queue. From now on we should not see "Illegal
342 State Transition" messages.
343 * Release host lock and enable interrupts when calling
344 del_timer_sync()
345 * All related to rports: Clean up issues with rport deletion
346 Convert to using block/unblock on list remove (was del/add)
347 Moved rport delete to freenode - so rport tracks node.
348 * rport fixes: for fport, get maxframe and class support
349 information
350 * Added use of wait_event to work with kthread interface.
351 * Ensure that scsi_transport_fc.h is always pulled in by
352 lpfc_scsiport.c
353 * In remote port changes: no longer nulling target->pnode when
354 removing from mapped list. Pnode get nulled when the node is
355 freed (after nodev tmo). This bug was causing i/o recieved in
356 the small window while the device was blocked to be errored w/
357 did_no_connect. With the fix, it returns host_busy
358 (per the pre-remote port changes).
359 * Merge in support for fc transport remote port use. This removes
360 any consistent bindings within the driver. All scanning is now
361 on a per-target basis driven by the discovery engine.
362
363Changes from 20041220 to 20041229
364
365 * Changed version number to 8.0.19
366 * Fixed bug for handling RSCN type 3. Terminate RSCN mode
367 properly after ADISC handling completes.
368 * Add list_remove_head macro. Macro cleans up memory allocation
369 list handling. Also clean up lpfc_reset_bus_handler - routine
370 does not need to allocate its own scsi_cmnd and scsi_device
371 structures.
372 * Fixed potential discovery bug, nlp list corrutpion fix potential
373 memory leak
374 * Part 1 of the memory allocation rework request by linux-scsi.
375 This effort fixes the number of bdes per scsi_buf to 64, makes
376 the scatter-gather count a module parameter, builds a linked
377 list of scsi_bufs, and removes all dependencies on lpfc_mem.h.
378 * Reverted lpfc_do_dpc, probe_one, remove_one to original
379 implementation. Too many problems (driver not completing
380 initial discovery, and IO not starting to disks). Backs out
381 kthread patch.
382 * Fix race condition in lpfc_do_dpc. If wake_up interrupt occurs
383 while lpfc_do_dpc is running disc_done and the dpc list is
384 empty, the latest insertion is missed and the schedule_timeout
385 does not wakeup. The sleep interval is MAX_SCHEDULE_TIMEOUT
386 defined as ~0UL >> 1, a very large number. Hacked it to 5*HZ
387 for now.
388 * Fixed bug introduced when discovery thread implementation was
389 moved to kthread. kthread_stop() is not able to wake up thread
390 waiting on a semaphore and "modprobe -r lpfc" is not always
391 (most of the times) able to complete. Fix is in not using
392 semaphore for the interruptable sleep.
393 * Small Makefile cleanup - Remove remnants of 2.4 vs. 2.6
394 determination.
395
396Changes from 20041213 to 20041220
397
398 * Changed version number to 8.0.18
399 * Janitorial cleanup after removal of sliinit and ringinit[] ring
400 statistic is owned by the ring and SLI stats are in sli
401 structure.
402 * Integrated patch from Christoph Hellwig <hch@lst.de> Kill
403 compile warnings on 64 bit platforms: %variables for %llx format
404 specifiers must be caste to long long because %(u)int64_t can
405 just be long on 64bit platforms.
406 * Integrated patch from Christoph Hellwig <hch@lst.de> Removes
407 dead code.
408 * Integrated patch from Christoph Hellwig <hch@lst.de>: use
409 kthread interface.
410 * Print LPFC_MODULE_DESC banner in module init routine.
411 * Removed sliinit structure and ringinit[] array.
412 * Changed log message number from 324 to 326 in lpfc_sli.c.
413 * Wait longer for commands to complete in lpfc_reset_bus_handler
414 and lpfc_reset_bus_handler. Also use schedule_timeout() instead
415 of msleep() and add error message in lpfc_abort_handler()
416 * When setting lpfc_nodev_tmo, from dev_loss set routine, make 1
417 sec minimum value.
418 * Functions which assume lock being held were called without lock
419 and kernel complained about unlocking lock which is not locked.
420 * Added code in linkdown to unreg if we know login session will be
421 terminated.
422 * Removed automap config parameter and fixed up use_adisc logic to
423 include FCP2 devices.
424
425Changes from 20041207 to 20041213
426
427 * Changed version number to 8.0.17
428 * Fix sparse warnings by adding __iomem markers to lpfc_compat.h.
429 * Fix some sparse warnings -- 0 used as NULL pointer.
430 * Make sure there's a space between every if and it's (.
431 * Fix some overly long lines and make sure hard tabs are used for
432 indentation.
433 * Remove all trailing whitespace.
434 * Integrate Christoph Hellwig's patch for 8.0.14: if
435 pci_module_init fails we need to release the transport template.
436 (also don't print the driver name at startup, linux drivers can
437 be loaded without hardware present, and noise in the log for
438 that case is considered unpolite, better print messages only for
439 hardware actually found).
440 * Integrate Christoph Hellwig's patch for 8.0.14: Add missing
441 __iomem annotations, remove broken casts, mark functions static.
442 Only major changes is chaning of some offsets from word-based to
443 byte-based so we cans simply do void pointer arithmetics (gcc
444 extension) instead of casting to uint32_t.
445 * Integrate Christoph Hellwig's patch for 8.0.14: flag is always
446 LPFC_SLI_ABORT_IMED, aka 0 - remove dead code.
447 * Modified preprocessor #ifdef, #if, #ifndef to reflect upstream
448 kernel submission. Clean build with make clean;make and make
449 clean;make ADVANCED=1 on SMP x86, 2.6.10-rc2 on RHEL 4 Beta
450 1. IO with a few lips and a long cable pull behaved accordingly.
451 * Implement full VPD support.
452 * Abort handler will try to wait for abort completion before
453 returning. Fixes some panics in iocb completion code path.
454
455Changes from 20041130 to 20041207
456
457 * Changed version number to 8.0.16
458 * Hung dt session fix. When the midlayer calls to abort a scsi
459 command, make sure the driver does not complete post-abort
460 handler. Just NULL the iocb_cmpl callback handler and let SLI
461 take over.
462 * Add Read check that uses SLI option to validate all READ data
463 actually received.
464
465
466Changes from 20041123 to 20041130
467
468 * Changed version number to 8.0.15
469 * Ifdef'd unused "binary" attributes by DFC_DEBUG for clean
470 compiles
471 * Stop DID_ERROR from showing up along with QUEUE_FULL set by the
472 Clarion array (SCSI error ret. val. 0x70028) There is no need
473 for driver to hard fail command which was failed by the target
474 device.
475 * Fix for Scsi device scan bug reported on SourceForge. Driver
476 was returning a DID_ERROR in lpfc_handle_fcp_error causing
477 midlayer to mark report luns as failing even though it
478 succeeded.
479 * Don't ignore SCSI status on underrun conditions for inquiries,
480 test unit ready's, etc. This was causing us to lose
481 reservation conflicts, etc
482
483Changes from 20041018 to 20041123
484
485 * Changed version number to 8.0.14
486 * Added new function "iterator" lpfc_sli_next_iocb_slot() which
487 returns pointer to iocb entry at cmdidx if queue is not full.
488 It also updates next_cmdidx, and local_getidx (but not cmdidx)
489 * lpfc_sli_submit_iocb() copies next_cmdidx into cmdidx. Now it is
490 the only place were we are updating cmdidx.
491 * lpfc_sli_update_ring() is split in to two --
492 lpfc_sli_update_ring() and lpfc_sli_update_full_ring().
493 * lpfc_sli_update_ring() don't to read back correct value of
494 cmdidx.
495 * Simplified lpfc_sli_resume_iocb() and its use.
496 * New static function lpfc_sli_next_iocb(phba, pring, &piocb) to
497 iterate through commands in the TX queue and new command (at the
498 end).
499 * Reduced max_lun to 256 (due to issues reported to some arrays).
500 Fixed comment, and macro values so def=256, min=1, max=32768.
501 * Fix an obvious typo/bug: kfree was used to free lpfc_scsi_buf
502 instead of mempool_free in lpfc_scsiport.c.
503 * Suppress nodev_tmo message for FABRIC nodes.
504 * Fixed some usage of plain integer as NULL pointer.
505 * Bug fix for FLOGI cmpl, lpfc_els_chk_latt error path code
506 cleanup.
507 * Fixup lpfc_els_chk_latt() to have Fabric NPorts go thru
508 discovery state machine as well.
509 * Fixes to lpfc_els_chk_latt().
510 * Use DID not SCSI target id as a port_id and add some missing
511 locks in lpfc_fcp.c.
512 * Changed eh_abort_handler to return FAILED if command is not
513 found in driver.
514 * Fix crash: paging request at virtual address 0000000000100108 -
515 a result of removing from the txcmpl list item which was already
516 removed (100100 is a LIST_POISON1 value from the next pointer
517 and 8 is an offset of the "prev") Driver runs out of iotags and
518 does not handle that case well. The root of the proble is in the
519 initialization code in lpfc_sli.c
520 * Changes to work with proposed linux kernel patch to support
521 hotplug.
522 * Zero out seg_cnt in prep_io failure path to prevent double sg
523 unmap calls.
524 * Fix setting of upper 32 bits for Host Group Ring Pointers if in
525 SLIM. Old code was inappropriately masking off low order bits.
526 * Use scsi_[activate|deactivate]_tcq calls provided in scsi_tcq.h.
527 * Integrated patch from Christoph Hellwig (hch@lst.de): don't call
528 pci_dma_sync_* on coherent memory. pci_dma_sync_* is need and
529 must be used only with streaming dma mappings pci_map_*, not
530 coherent mappings. Note: There are more consistent mappings
531 that are using pci_dma_sync calls. Probably these should be
532 removed as well.
533 * Modified lpfc_free_scsi_buf to accomodate all three scsi_buf
534 free types to alleviate miscellaneous panics with cable pull
535 testing.
536 * Set hotplug to default 0 and lpfc_target_remove to not remove
537 devices unless hotplug is enabled.
538 * Fixed discovery bug: plogi cmpl uses ndlp after its freed.
539 * Fixed discovery bug: rnid acc cmpl, can potentially use ndlp
540 after its freed.
541 * Modularize code path in lpfc_target_remove().
542 * Changes to support SCSI hotplug (ifdef'ed out because they need
543 kernel support USE_SCAN_TARGET requires kernel support to export
544 the interface to scsi_scan_target and to move the SCAN_WILD_CARD
545 define to a general scsi header file. USE_RESCAN_HOST requires
546 kernel support to export an interface to scan_scsi_host() with
547 the rescan flag turned on).
548 * Removed redundant variable declaration of lpfc_linkdown_tmo.
549 * Fix for large port count remove test.
550 * Added check to see if BAR1 register is valid before using BAR1
551 register for programming config_port mail box command.
552 * Added lpfc_scsi_hotplug to enable/disable driver support of SCSI
553 hotplug.
554 * Changed lpfc_disc_neverdev() to lpfc_disc_illegal() and changed
555 lpfc_disc_nodev() to lpfc_disc_noop(). Adjusted appropriate
556 events to use these routines.
557 * Add support for SCSI device hotplug.
558 * Take dummy lpfc_target's into account for lpfc_slave_destroy().
559 * Bug fix to store WWPN / WWNN in NameServer / FDMI lpfc_nodelist
560 entries.
561 * Added slavecnt in lpfc_target for diagnostic purposes.
562 * Added lpfc_hba load/unload flags to take care of special cases
563 for add/remove device.
564 * Have target add/remove delay before scanning.
565 * Have rmmod path cleanup blocked devices before scsi_remove_host.
566 * Added a #define for msleep for 2.6.5 kernels.
567 * In reset bus handler if memory allocation fails, return FAILED
568 and not SUCCESS.
569 * Have lpfc eh handlers, bus_reset and lun_reset, wait for all
570 associated I/Os to complete before returning.
571 * Fix memset byte count in lpfc_hba_init so that
572 LP1050 would initialize correctly.
573 * Backround nodev_timeout processing to DPC This enables us to
574 unblock (stop dev_loss_tmo) when appopriate.
575 * Fix array discovery with multiple luns. The max_luns was 0 at
576 the time the host structure was intialized. lpfc_cfg_params
577 then set the max_luns to the correct value afterwards.
578 * Remove unused define LPFC_MAX_LUN and set the default value of
579 lpfc_max_lun parameter to 512.
580 * Reduced stack usage of lpfc_hba_init.
581 * Cleaned up the following warning generated by
582 scripts/checkincludes.pl lpfc_fcp.c: scsi/scsi_cmnd.h is
583 included more than once.
584 * Replaced "set_current_state(TASK_UNINTERRUPTIBLE);
585 schedule_timeout(timeout)" with "msleep(timeout)".
586 * Fixnode was loosing starget when rediscovered. We saw messages
587 like: lpfc 0000:04:02.0: 0:0263 Cannot block scsi target as a
588 result. Moved starget field into struct lpfc_target which is
589 referenced from the node.
590 * Add additional SLI layer logging in lpfc_sli.c.
591 * Ignore more unexpected completions in lpfc_nportdisc.c.
592 * Can not call lpfc_target_unblock from the soft interrupt
593 context. It seems to be not nessasery to unblock target from
594 nodev timeout.
595 * Introduce and use less lethal event handler for unexpected
596 events in lpfc_nportdisc.c.
597 * Can not call fc_target_(un)block() functions with interrupts
598 disabled in lpfc_scsiport.c.
599 * Added new configuration parameter, lpfc_max_luns range 1-32768,
600 default 32768.
601 * Allow lpfc_fcp.c to call lpfc_get_hba_sym_node_name().
602 * Increase nodev timeout from 20 seconds to 30 seconds.
603 * Replace some kfree((void*)ptr) with kfree(ptr).
604 * Make 3 functions static: lpfc_get_hba_sym_node_name,
605 lpfc_intr_prep and lpfc_setup_slim_access. Move lpfc_intr_prep
606 and lpfc_setup_slim_access so they're defined before being used.
607 * Remove an unecessary list_del() in lpfc_hbadisc.c.
608 * Set nlp_state before calling lpfc_nlp_list() since this will
609 potentially call fc_target_unblock which may cause a race in
610 queuecommand by releasing host_lock.
611 * Since lpfc_nodev_tmo < dev_loss_tmo remove queuecommand
612 DID_BAD_TARGET return for now.
613 * Fix a problem with rcv logo.
614 * Remove unused portstatistics_t structure.
615 * Remove #if 0 and unnecessary checks in lpfc_fcp.c.
616 * Simplify lpfc_issue_lip: Extra layer of protection removed.
617 * Grab lock before calling lpfc_sli_issue_mbox(phba, pmb,
618 MBX_NOWAIT) in lpfc_sli_issue_mbox_wait().
619
620Changes from 20040920 to 20041018
621
622 * Changed version number to 8.0.13
623 * Hide some attributes using #ifndef DFC_DEBUG ... #endif.
624 * Modify Makefile to (1) make BUILD_NO_DEBUG=1 will hide some
625 (binary) attributes (2) make BUILD_FC_TRANS=0 will build driver
626 for 2.6.5 kernel with block/unblock patch.
627 * Modified #ifdef names.
628 * Added support for proposed FC transport host attributes (which
629 replaces some of the attributes we had local to the driver).
630 Removed the binary statistics sysfs attribute.
631 * Added extra ELS verbose logging for ELS responses.
632 * Added recognition for BUILD_FC_TRANS=2 to Makefile to define
633 FC_TRANS_VER2.
634 * Add a pointer for link stats allocation.
635 * Exported lpfc_get_hba_sym_node_name for use by FC_TRANS_VER2
636 sysfs routines.
637 * Fix discovery problem in lip testing: if device sends an ELS cmd
638 (i.e. LOGO) before our FLOGI completes it should be LS_RJT'ed.
639 * Moved #defines around to provide target_add/remove for upstream
640 kernel deliverables only not SLES9. Provided ifdefs to #include
641 target_block/unblock only if FC_TRANS_VER1.
642 * Add sanity check in lpfc_nlp_list move setting nlp_Target
643 outside #ifdef.
644 * Added a blocked member to the lpfc_target structure for
645 block/unblock. This member allows the driver to know when to
646 unblock for pci_remove_one or pci_add_one. #ifdef'd some more
647 block/unblock stuff and removed some defensive checks from
648 target_block/unblock.
649 * Moved + 5 second window to dev_loss_tmo setting and updated
650 comments.
651 * Removed NULL target check from target_block/unblock and fixed up
652 a few comments.
653 * Enable sysfs attributes on 2.6.5 kernels and remove extra
654 compatibility code.
655 * Remove any and all trailing whitespace.
656 * Added message 0718 and return error when dma_map_single fails.
657 * Changed the fcpCntl2 commands to include an FCP_ prefix to get
658 rid of build warnings on later 2.6.9-rc kernels. Build
659 conflicts with scsi/scsi.h. Remove inclusions of scsi/scsi.h
660 from hbadisc.c, sli.c, and fcp.c since these modules had no
661 dependencies on scsi.h.
662 * Fixed a bug with RSCN handling. A RSCN received on one device,
663 shouldn't affect other devices not referenced by the RSCN.
664 * Moved #if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,6) to include
665 lpfc_jedec_to_ascii to prevent warning in SLES 9.
666 * Update Makefile to account for SLES 9 and scsi-target upstream
667 kernel.
668 * This checkin provides block/unblock hooks for the upstream scsi
669 target kernel and 2.6.5 on SLES9 SP1 with the block/unblock
670 patch.
671 * Discovery changes regarding setting targetp->pnode and
672 ndlp->nlp_Target Ensure fc_target_* routines are called properly
673 from discovery. Remove list_del's from lpfc_cleanup(). Ensure
674 all the lpfc_consistent_bind_* routines don't set any driver
675 structure objects.
676 * Fix for timeout of READ_LA or READ_SPARAM mailbox command
677 causing panic.
678 * Cleanup list_del()'s for Discovery ndlp lists.
679 * Bug fixes for some insmod/rmmod crashes, link down crashes and
680 device loss crashes.
681 * Removed NLP_SEARCH_DEQUE.
682 * Call lpfc_target_unblock only if the targetp is nonNull and with
683 the host_lock held.
684 * Added qcmdcnt back along with misc bug fixes to discovery.
685 * Changed tgt_io to outfcpio lpfc_fcp.c.
686 * Fixed errors caused by LIP and cable pulls both with and without
687 block/unblock patch.
688 * For now we have to call fc_target_unblock and fc_target_block
689 with interrupts enabled.
690 * Save seg_cnt from dma_map_sg. Save scatter-gather start address
691 and pass back to dma_unmap_sg in error with seg_cnt.
692 * Incorporating block/unblock calls into driver with ifdefs. This
693 change is supported by scsi-target-2.6 kernel and forward only.
694 * Merged in some discovery bug fixes and added tgt io counters.
695 * Added sysfs attributes/interfaces: read only attribute
696 "management_version" and write only attribute "issue_lip".
697 * Fix build on big endian machines: while #if was OK with
698 __BIG_ENDIAN which defined as 4321, __BIG_ENDIAN_BITFIELD has to
699 be tested with #ifdef because it does not have any value, it is
700 either defined or not.
701 * Add fabric_name and port_type attributes.
702 * Change mdelay to msleep. mdelay works, but wastefully uses cpu
703 resources without a lock held. Revert to msleep. Tested with
704 sg_reset for bus and three attached targets.
705 * Added the customary #ifndef...#define...#endif to
706 lpfc_version.h.
707 * Integrate patches from Christoph Hellwig: two new helpers common
708 to lpfc_sli_resume_iocb and lpfc_sli_issue_iocb - singificant
709 cleanup of those two functions - the unused SLI_IOCB_USE_TXQ is
710 gone - lpfc_sli_issue_iocb_wait loses it's flags argument
711 totally.
712 * Fix in lpfc_sli.c: we can not store a 5 bit value in a 4-bit
713 field.
714 * Moved some routines out of lpfc_fcp.c into more appropriate
715 files.
716 * Whitespace cleanup: remove all trailing whitespace.
717 * Make lpfc_disc_ndlp_show static to lpfc_fcp.c.
718 * Remove leftover printk and replace some with
719 printk(KERN_WARNING)
720 * Trivial: fix a few long lines and a soft tab.
721 * Remove warnings generated by Sparse against driver (make
722 C=1). Mostly these are "using integer as pointer warnings"
723 i.e. use NULL instead of 0.
724 * Integrated patch from Christoph Hellwig: Quite a lot of changes
725 here, the most notable is that the phba->slim2p lpfc_dmabuf goes
726 away in favour of a typede pointer and a dma_addr_t. Due to the
727 typed pointer lots of the cast mess can go away, and while at it
728 I also replaced the messy SLI2_SLIM_t with a simple struct
729 lpfc2_sli2_slim that only contains the part of the union we care
730 about while using SLI2_SLIM_SIZE for all size calculations
731 directly.
732 * Integrated patch from Christoph Hellwig: This streamlines the
733 I/O completion path a little more, especially taking care of
734 fast-pathing the non-error case. Also removes tons of dead
735 members and defines from lpfc_scsi.h - e.g. lpfc_target is down
736 to nothing more then the lpfc_nodelist pointer.
737 * Added binary sysfs file to issue mbox commands
738 * Replaced #if __BIG_ENDIAN with #if __BIG_ENDIAN_BITFIELD for
739 compatibility with the user space applications.
740 * Decrease the amount of data in proc_info.
741 * Condense nodelist flag members.
742 * Expand INFO for discovery sysfs shost entries.
743 * Notify user if information exceeds 4k sysfs limit.
744 * Removed a bunch of unused #defines.
745 * Added initial sysfs discovery shost attributes.
746 * Remove unused #defines lpfc_disc.h.
747 * Fixed failMask nodelist settings.
748 * Cleanup some old comments / unused variables.
749 * Add LP101 to list of recognized adapters.
750
751Changes from 20040908 to 20040920
752
753 * Changed version number to 8.0.12
754 * Removed used #defines: DEFAULT_PCI_LATENCY_CLOCKS and
755 PCI_LATENCY_VALUE from lpfc_hw.h.
756 * Changes to accomodate rnid.
757 * Fix RSCN handling so RSCN NS queries only effect NPorts found in
758 RSCN data.
759 * If we rcv a plogi on a NPort queued up for discovery, clear the
760 NLP_NPR_2B_DISC bit since rcv plogi logic will force NPort thru
761 discovery.
762 * Ensure lpfc_target is also cleaned up in lpfc_cleanup().
763 * Preliminary changes for block/unblock kernel API extensions in
764 progress with linux-scsi list. These are name changes and
765 prototype changes only.
766 * Added send_abts flag to lpfc_els_abort. For rcv LOGO when ADISC
767 sent, the XRI of the LOGO rcv'ed is the same as the ADISC
768 sent. Thus we cannot ABTS the ADISC before sending the LOGO ACC.
769 * Weed out some unused fc_flags. Add FC_DISC_TMO.
770 * board_online sysfs attribute added to support libdfc functions
771 InitDiagEnv and SetBrdEnv.
772 * Streamline code in lpfc_els_retry fixup abort case in
773 lpfc_els_timeout_handler().
774 * Flush discovery/ELS events when we bring SLI layer down.
775 * ctlreg and slimem binary attributes added to support libdfc
776 read/write mem/ctl functions.
777 * Integrated Christoph Hellwig's patch: Cleanup
778 lpfc_sli_ringpostbuf_get.
779 * Modified lpfc_slave_alloc and lpfc_slave_destroy to allocate and
780 free a dummy target pointer. This allows queuecommand to skip
781 the NULL target pointer check and avoid the console spam when
782 slave_alloc fails.
783 * Fix cfg_scan_down logic, it was reversed.
784 * Init list head ctrspbuflist.
785 * Change name of lpfc_driver_abort to lpfc_els_abort since it is
786 only valid for ELS ring.
787 * Remove unused third argument for lpfc_consistent_bind_get().
788 * Fix up iotag fields in lpfc_prep_els_iocb().
789 * Remove log message on code path triggered by lpfc_els_abort().
790 * Set host->unique_id in lpfc_fcp.c.
791 * Removed deadwood: lpfc_target.pHba not necessary anymore.
792 * Integrated patch from Christoph Hellwig: remove dead
793 SLI_IOCB_POLL handling.
794 * Integrated patch from Christoph Hellwig: Streamline I/O
795 submission and completion path a little.
796 * Remove unnecessary lpfc_brd_no. Ensure brd_no assignment is
797 unique.
798 * Removed unused MAX_FCP_LUN.
799 * Use mod_timer instead of add_timer for fdmi in lpfc_ct.c.
800 * Fixed misc discovery problems.
801 * Move stopping timers till just before lpfc_mem_free() call.
802 * Fix up NameServer reglogin error path.
803 * Cleanup possible outstanding discovery timers on rmmod.
804 * Fix discovery NPort to NPort pt2pt problem.
805 * Get rid of ip_tmofunc / scsi_tmofunc.
806 * Integrated patch from Christoph Hellwig:
807 lpfc_disc_done/lpfc_do_dpc cleanup - lpfc_disc_done can return
808 void - move lpfc_do_dpc and lpfc_disc_done to lpfc_hbadisc.c -
809 remove checking of list emptiness before calling lpfc_disc_done,
810 it handles the emtpy list case just fine and the additional
811 instructions cost less then the bustlocked spinlock operations.
812 * Integrated patch from Christoph Hellwig: This adds a new 64bit
813 counter instead, brd_no isn't reused anymore. Also some tiny
814 whitespace cleanups in surrounding code.
815 * Reorder functions in lpfc_els.c to remove need for prototypes.
816 * Removed unsed prototypes from lpfc_crtn.h -
817 lpfc_ip_timeout_handler, lpfc_read_pci and lpfc_revoke.
818 * Removed some unused prototypes from lpfc_crtn.h -
819 lpfc_scsi_hba_reset, lpfc_scsi_issue_inqsn,
820 lpfc_scsi_issue_inqp0, lpfc_scsi_timeout_handler.
821 * Integrated patch from Christoph Hellwig: remove TRUE/FALSE
822 usage.
823 * Integrated patch from Christoph Hellwig: Remove unused function
824 prototypes lpfc_set_pkt_len and lpfc_get_pkt_data from
825 lpfc_crtn.h - fixes build warnings.
826 * Removed unused struct lpfc_dmabufip definition from lpfc_mem.h.
827 * Removed pre-2.6.5 MODULE_VERSION macro from lpfc_compat.h.
828 * Fixing missing static and removing dead code.
829 * Adding nodewwn, portwwn and portfcid shost attributes.
830 * Initial support for CT via sysfs. request payloads of size less
831 than PAGE_SIZE and rsp payloads of size PAGE_SIZE are supported.
832 Driver maintains a list of rsp's and passes back rsp's
833 corresponding to the pid of the calling process.
834 * Support for RefreshInformation, GetAdapterAttributes,
835 GetPortStatistics.
836 * Make nodev-tmo default to 20 seconds.
837 * Fix up some DSM error cases, unreg_login rpi where needed.
838 * Fix up comments for fc_target_block / fc_target_unblock.
839 * Fix up code for scsi_block_requests / scsi_unblock_requests.
840 * Add NLP_FCP_TARGET for nodeinfo support.
841 * Move suspend/resume in lpfc_nlp_list under appropriate case -
842 Used host_lock for DPC to avoid race (remove dpc_lock)
843 * Fix some corner cases for PLOGI receive - simplify error case
844 for cmpl_reglogin_reglogin_issue.
845 * Bug fix for ppc64 EEH MMIO panic - always do readl after
846 writel's of HBA registers to force flush.
847 * Get rid of initial static routine declarations in lpfc_hbadisc.c
848 and lpfc_els.c.
849 * Updates to discovery processing.
850
851Changes from 20040823 to 20040908
852
853 * Changed version number to 8.0.11
854 * Removed persistent binding code.
855 * Display both ASC and ASCQ info.
856 * Fixed link down->up transitions when linkdown tmo expires. Fix
857 was in the defensive error checking at the start of
858 queuecommand.
859 * Removed lpfc_scsi_timeout_handler as this timer is no longer
860 required. The midlayer will exhaust retries and then call
861 lpfc_abort_handler, lpfc_reset_lun_handler, and
862 lpfc_reset_target_handler.
863 * Minimal support for SCSI flat space addressing/volume set
864 addressing. Use 16 bits of LUN address so that flat
865 addressing/VSA will work.
866 * Changed 2 occurences of if( 1 != f(x)) to if(f(x) != 1)
867 * Drop include of lpfc_cfgparm.h.
868 * Reduce stack usage of lpfc_fdmi_cmd in lpfc_ct.c.
869 * Add minimum range checking property to /sys write/store
870 functions.
871 * Fix display of node_name and port_name via fc transport
872 attr.
873 * Removed biosparam code.
874 * Removed range checking. phba->config[] array elements are now
875 embedded into the hba struct. lpfc_config_setup() has been
876 removed.
877 * Collapsed lpfc_scsi_cmd_start into lpfc_queuecommand and cleaned
878 up combined routines.
879 * Removed unused prototypes myprint and
880 lpfc_sched_service_high_priority_queue.
881 * Removed unused function lpfc_nodev.
882 * Removed scsi_cmnd->timeout_per_command cancelation. SCSI midlayer
883 now times out all commands - FW is instructed to not timeout.
884 * Removed polling code from lpfc_scsi_cmd_start. Reorganized
885 queuecommand and cmd_start some.
886
887Changes from 20040810 to 20040823
888
889 * Changed version number to 8.0.10
890 * Additional timer changes as per Arjan / Christoph's comments.
891 * Used mod_timer() instead of del_timer_sync() where appropriate.
892 * Fixed a use after free case (panic on 2.6.8.1 with
893 CONFIG_DEBUG_SLAB set).
894 * Fix compile warning in lpfc_fcp.c.
895 * Minor fix for log message, that prints unassigned brdno which is
896 zero.
897 * Move scsi_host_alloc() to the beginning of probe_one(). This
898 ensures that host_lock is available at later stages and also
899 avoids tons of unnecessary initializing if host_alloc()
900 fails.
901 * Removed else clause from lpfc_slave_configure that set
902 sdev->queue_depth. The driver informs the midlayer of its
903 setting in the template and only overrides if queue tagging is
904 enabled.
905 * Added PCI_DEVICE_ID_ZEPHYR and PCI_DEVICE_ID_ZFLY (Junior
906 Zephyr) support
907
908Changes from 20040730 to 20040810
909
910 * Changed version number to 8.0.9
911 * Removed per HBA driver lock. Driver now uses the host->host_lock
912 * Restored support for the 2.6.5 kernel for those linux distributions
913 shipped with the 2.6.5 kernel.
914 * Applied patch from Christoph Hellwig (hch@infradead.org) as follows
915 "[PATCH] use scsi host private data in ->proc_info.
916 * Applied patch from Christoph Hellwig (hch@infradead.org) as follows
917 "Re: [Emulex] Ready for next round. This patch cleans up the memory
918 allocation routines a little and fixes a missing mempool_destroy and
919 some missing error handling."
920 * Changed pointers assignments from 0 to NULL.
921 * Added fixes to the lpfc_reset_lun_handler and lpfc_reset_bus_handler
922 entry points that caused kernel to Oops or hang.
923 * Added fixes to targetless hosts that caused modprobe and insmod to hang.
924 * Ongoing cleanup to many files
925
926Changes from 20040723 to 20040730
927
928 * Changed version number to 8.0.8

931 caller.
932 * Removed 2 unneeded arguments to lpfc_find_target (lun and
933 create_flag).
934 * Make lpfc_sli_reset_on_init = 1
935 * Minor cleanup to quieten sparse.
936 * Removed missing function = 0 in tmo routine in lpfc_els.c.
937 * Moved additional binding parameters into lpfc_defaults.c:
938 lpfc_automap / lpfc_fcp_bind_method
939 * Use msecs_to_jiffies() where applicable.
940 * Only use queue depth attribute only after SLI HBA setup was
941 completed.
942 * Put in memory barriers for PPC
943 * Added PCI_DEVICE_ID_HELIOS and PCI_DEVICE_ID_JFLY (Junior
944 Helios) support
945 * Added 4&10 gigabit choices in user option link_speed
946 * Updated timer logic: Set timer data after init_timer use
947 timer_pending() instead of expires.
948 * Removed some remnants of IP over FC support from Kconfig and
949 Makefile.
950 * Remove redundant prototypes for lpfc_handle_eratt,
951 lpfc_handle_latt and lpfc_read_pci.
952 * Ongoing cleanup of lpfc_init.c.
953 * Changed LPFC_CFG_DFT_HBA_Q_DEPTH -> LPFC_CFG_HBA_Q_DEPTH.
954 * Another cleanup stab at lpfc_ct.c. Remove castings, structure
955 code sanely, remove redundant code, reorganize code so that
956 functions are invoked after definition.
957
958Changes from 20040716 to 20040723
959
960 * Changed version number to 8.0.7
961 * Cleanup of lpfc_ct.c. Removed number of casts, removed tons of
962 dead/redundant code, cleaned up badly and poorly written code,
963 cleaned up return values.
964 * Fixed Persistent binding implementation
965 * Removed all references to lpfc_scsi_req_tmo
966 * Removed last references to lun_skip config parameter.
967 * Removed LPFC_DEV_RPTLUN node failure bit because we don't issue
968 REPORT_LUNS from the driver anymore.
969 * Removed LUN-tracking in driver. Removed lpfc_lun struct and
970 moved any functionality we still need to lpfc_target.
971 * Added new lpfc_jedec_to_ascii() call and replace two instances
972 of duplicate code with calls to this function.
973 * Removed Volume Set Addressing handling on LUN IDs.
974 * Applied patch from Christoph Hellwig (hch@infradead.org) that
975 removes dead code belonging to lpfc_build_scsi_cmnd() and its
976 call path. This is related to the recently removed report_lun
977 code.
978
979Changes from 20040709 to 20040716
980
981 * Changed version number to 8.0.6
982 * Removed internal report LUNs usage. Removed functions:
983 lpfc_disc_issue_rptlun, lpfc_disc_cmpl_rptlun,
984 lpfc_disc_retry_rptlun and their use.
985 * Removed usused scheduler prototypes in lpfc_crtn.h
986 * Replace lpfc_geportname() with generic memcmp().
987 * Rearrange code in lpfc_rcv_plogi_plogi_issue() to make it a
988 little more readable.
989 * Remove redundant port_cmp != 2 check in if
990 (!port_cmp) { .... if (port_cmp != 2).... }
991 * Clock changes: removed struct clk_data and timerList.
992 * Clock changes: seperate nodev_tmo and els_retry_delay into 2
993 seperate timers and convert to 1 argument changed
994 LPFC_NODE_FARP_PEND_t to struct lpfc_node_farp_pend convert
995 ipfarp_tmo to 1 argument convert target struct tmofunc and
996 rtplunfunc to 1 argument * cr_count, cr_delay and
997 discovery_threads are only needed to be module_params and not
998 visible via sysfs.
999
1000Changes from 20040614 to 20040709
1001
1002 * Changed version number to 8.0.5

1008 * Changed CSP to struct csp.
1009 * Changed CLASS_PARMS to struct class_parms.
1010 * Some cosmetic coding style cleanups to lpfc_fcp.c.
1011 * Providing a sysfs interface that dumps the last 32
1012 LINK_[UP|DOWN] and RSCN events.
1013 * Get rid of delay_iodone timer.
1014 * Remove qfull timers and qfull logic.
1015 * Convert mbox_tmo, nlp_xri_tmo to 1 argment clock handler
1016 * Removed duplicate extern defs of the bind variables.
1017 * Streamline usage of the defines CLASS2 and CLASS3, removing
1018 un-necessary checks on config[LPFC_CFG_FCP_CLASS].
1019 * Moving the persistent binding variables to new file
1020 lpfc_defaults.c
1021 * Changed LPFC_SCSI_BUF_t to struct lpfc_scsi_buf.
1022 * Moved config specific code from probe_one() into
1023 config_setup(). Removing a redundant check on scandown value
1024 from bind_setup() as this is already done in config_setup().
1025 * Changed LPFC_SLI_t to struct lpfc_sli.
1026 * Changed FCP_CMND to struct fcp_cmnd.
1027 * Changed FCP_RSP to struct fcp_rsp.

1036 lpfc_tgt_queue_depth and lpfc_check_cond_err.
1037 * Clock changes consolidating timers, just in the struct lpfc_hba,
1038 to get rid of clkData and pass only one argument to timeout
1039 routine. Also, removing need for outstanding clock linked list
1040 to stop these timers at rmmod.
1041 * Move lpfc.conf contents into lpfc_fcp.c. Removing per adapter
1042 attributes in favor of global attributes.
1043 * Fix a potential null pointer reference of pmbuf in lpfc_ct.c.
1044 * On reset_lun, issue LUN_RESET as opposed to ABORT_TASK_SET.
1045 * Removed SCSI_REQ_TMO related code.
1046 * Introducing two new defines LPFC_ATTR_R and LPFC_ATTR_RW that do
1047 a module_param, MODULE_PARM_DESC, lpfc_param_show,
1048 [lpfc_param_store] and CLASS_DEVICE_ATTRIBUTE.
1049 * Properly clean up when allocation of a linked BDE fails in the
1050 SCSI queuecommand path.
1051 * Fail SCSI command if dma_map_sg call fails.
1052 * Remove unused macros SWAP_ALWAYS and SWAP_ALWAYS16.
1053 * Reset context2 to 0 on exit in
1054 lpfc_sli_issue_iocb_wait_high_priority() and
1055 lpfc_sli_issue_iocb_wait().
1056 * Arranging lpfc_scsiport.c to follow style of use after
1057 definition. This removes the need for the cruft of forward
1058 declarations. Also removing a redundant #define ScsiResult as it
1059 already available elsewhere.
1060 * Applying "Streamline lpfc error handling" patch from Christoph
1061 Hellwig (hch@infradead.org) with following modifications: fix
1062 mem leaks, remove some misplaced code that need not be there,
1063 print a message on exit (old code prints two (entry/exit)), make
1064 ret values consistent (either 1/0 or SUCCESS/FAILURE), keep all
1065 eh routines in a single file (lpfc_scsiport.c).
1066 * Move contents of lpfc_module_param.h into lpfc_fcp.c.
1067 * Changed sysfs attributes to CLASS_DEVICE_ATTRIBUTES (previously
1068 DEVICE_ATTRIBUTES). They now appear in
1069 /sys/class/scsi_host/hostx (previously in
1070 /sys/bus/pci/drivers/lpfc/devx).
1071 * Removed lpfc_syfs.h and lpfc_sysfs.c.
1072 * Cleanup of config params. Throttle params have been removed.
1073 max_lun has been removed. max_target is replaced with a #define,
1074 lun_skip is removed. Remove ipfc config params and related
1075 code.
1076 * Changed DMABUF_t usage to struct lpfc_dmabuf.
1077 * Downsizing iCfgParam structure to include a_string, a_low, a_hi
1078 and a_default values only.
1079 * Free SCSI buf safety memory pool on shutdown to eliminate memory
1080 leak.
1081 * Change lpfc_printf_log to a #define. Also include phba->brd_no
1082 and newline in the print string rather than in the #define.
1083 * Remove code that optionally locates Host Group Pointers in host
1084 memory SLIM since this is no longer needed for PPC64, once
1085 CONFIG_PORT uses HBA's view of its BAR0.
1086 * Removed the forward declarations of the sli functions and
1087 rearranging the code in lpfc_sli.c.
1088 * Removed the preamble functionality from logging.
1089 * Make lpfc_sli_hba_setup() return negative error codes on error
1090 and correct the comment left over in lpfc_fcp.c
1091 * Removed the lpfc_loadtime variable.
1092 * Put a space between all ifs and their open parens '('.
1093 * Change Studly_Caps LPFC_SCSI_BUF_t to struct lpfc_scsi_buf.
1094 * Fixed insmod hang after hardware error.
1095 * Relocated scsi_host alloc to before we enable the interrupt
1096 handler
1097 * Add .tmp_versions directory to Makefile clean target. This
1098 directory is created in the 2.6.5+ build process (with Red Hat
1099 kernels at least).
1100 * Changing phba->config to kmalloc lpfc_icfgparam and not
1101 *phba->config. This is manifesting itself as a panic in
1102 pci_release_region().
1103 * Fix for firmware download / board reset problem.
1104 * Integrated patch from Christoph Hellwig (hch@infradead.org) to
1105 reorganize and cleanup lpfc_fcp.c
1106 * Don't abort commands immediately when there is an RSCN event to
1107 give driver time to rediscover targets before the midlayer
1108 retries the SCSI commands.
1109
1110Changes from 20040604 to 20040614
1111
1112 * Changed version number to 8.0.4
1113 * Removed lpfc_valid_lun function.
1114 * Added scsi_buf safety pool to address scsi_buf failures in
1115 queuecommand under low memory conditions. Allocations now come
1116 from kmalloc initially, but if kmalloc fails, the allocation
1117 comes from the safety pool.
1118 * Modified lpfc_slave_alloc to only set the scsi_device->hostdata
1119 pointer if the driver has discovered the target. This routine
1120 always returns success now as well since no error ever occurs in
1121 the alloc routine.
1122 * Mask only info and warning messages. Print all error messages
1123 irrespective of mask.
1124 * Removing lpfc_log_chk_msg_disabled()
1125 * Changed lpfc_printf_log to take struct lpfc_hba * directly
1126 instead of a "board number".
1127 * Convert dma_sync_single to pci_dma_sync_single_for_{device/cpu}.
1128 * Implemented new style log messages. The message strings are now
1129 embedded in the call to lpfc_printf_log.
1130 * Decreased FLOGI discovery timeout to 20 seconds.
1131 * On error in lpfc_pci_probe_one() return -1 and not 1.
1132 * Allow for board numbers that are not sequential, paving the way
1133 for hotplug support.
1134 * scsi_add_host() can fail, so wrap it around in an if(). Also
1135 initiate scsi_scan_host() after attaching the sysfs attributes.
1136 * lpfc_release_version is used only in lpfc_ct.c, so move it there
1137 and mark it as static.
1138 * Removed lpfc_sleep_ms and replaced with mdelay or schedule calls
1139 directly
1140 * Removed all (struct list_head *) casts from clkData-related list
1141 handling in list_add, list_del macros.
1142 * Removed EXPORT_SYMBOLs.
1143 * Removed LPFC_MIN_QFULL and lpfc_qthrottle_up.
1144 * Replace LPFCSCSITARGET_t with struct lpfc_target.
1145 * Replace LPFCSCSILUN_t with struct lpfc_lun.
1146 * Remove unused struct declarations (fcPathId and fcRouteId) from
1147 lpfc_scsi.h.
1148 * Rewrite use of FC transport attributes.
1149 * Fix crash when link is lost. This was due to lpfc_delay_iodone
1150 calling list_del on an object that was never put on a list.
1151 * Remove trailing spaces at the end of all lines.
1152 * Set MAX_FCP_TARGET to 256 from 0xff. Set MAX_FCP_LUN and
1153 MAX_FCP_CMDS to their decimal equivalents and updated
1154 documentation.
1155
1156Changes from 20040526 to 20040604
1157
1158 * Changed version number to 8.0.3
1159 * Completed sysfs FC transport support.
1160 * Removed unused fields in SCSI LUN and SCSI Target structures:
1161 void *pTargetProto; void *pTargetOSEnv; void *pLunOSEnv;
1162 * Modified list_for_each to list_for_each_entry. Modified
1163 list_for_each_safe to list_for_each_entry_safe.
1164 * Remove lpfc_dfc.h file.
1165 * Changed pHba->phba, pCommand->pcmd
1166 * Changed plogi_ndlp -> plogindlp, pos_tmp->postmp, pRsp->prsp,
1167 pCmd->pcmd
1168 * Changed pText -> ptext
1169 * Changed p_tmp_buff -> ptmpbuff
1170 * Changed pBufList -> pbuflist, pRsp -> prsp, pCmd -> pcmd
1171 * Changed *pos_tmp -> *postmp, *p_mbuf -> *pmbuf
1172 * Following changes are made to the SCSI fast path: Added
1173 DMA_BUF_t member to the lpfc_scsi_buf_t. This will reduce a
1174 memory allocation in the scsi fast path. Added check for
1175 targetp == NULL in the scsi fast path. Increased number of
1176 scatter gather entries in lpfc_scsi_dma_ext to 4 from 3 and
1177 changed the size of lpfc_scsi_dma_ext to 264
1178 * Fixing some missing static lpfc_nportdisc.c.
1179 * Reordered #include lines so that lpfc.h doesn't have to #include
1180 other header files.
1181 * Remove lpfc_get_hba_sym_node_name() as a global EXPORT and make
1182 it static.
1183 * Move struct clk_data definition from lpfc_hw.h to lpfc_sli.h.
1184 * Changed LPFC_IOCBQ_t to struct lpfc_iocbq.
1185 * Changed LPFC_SLI_RING_t to struct lpfc_sli_ring.
1186 * Changed LPFC_NODELIST_t to struct lpfc_nodelist.
1187 * Rearranged lpfc_nportdisc.c by moving state machine array
1188 (lpfc_disc_action) and the one function that uses it,
1189 lpfc_disc_state_machine, to the end of the file, removing the
1190 need for the raft of prototypes at the top.
1191 * Changed LPFC_BINDLIST_t to struct lpfc_bindlist.
1192 * Removed lpfc_issue_ct_rsp(), lpfc_sleep(), lpfc_add_bind(),
1193 lpfc_del_bind(), lpfc_sli_wake_mbox_wait() and
1194 lpfc_sli_issue_mbox_wait().
1195 * Fixed a large number of overly-long lines.
1196 * Fixed some discovery problems: Introduced deferred ndlp removal
1197 when in DSM to avoid panic when in nested DMSs Fix NportId
1198 fffc01 handling to not relogin after LOGO fixed handling of LOGO
1199 on PLOGI issue.
1200 * Changed SLI_CT_REQUEST to lpfc_sli_ct_request.
1201 * Changed NAME_TYPE to struct lpfc_name.
1202 * Changed lpfcCfgParam_t to struct lpfc_cfgparam.
1203 * Changed LPFC_STAT_t to struct lpfc_stats.
1204 * Changed HBAEVT_t to struct lpfc_hba_event.
1205 * Changed Studly_Caps lpfcHBA_t to struct lpfc_hba.
1206 * Removed no longer used tasklet_running flag.
1207 * Removing *PSOME_VAR typedefs and using SOME_VAR* directly.
1208 * Changing .use_clustering to ENABLE_CLUSTERING.
1209 * Modify lpfc_queuecommand to return SCSI_MLQUEUE_HOST_BUSY when
1210 it can't queue a SCSI command. Also, remove cmnds_in_flight
1211 member of struct lpfcHBA for 2.6 kernels as it was only needed
1212 to determine what to return from queuecommand.
1213 * Change return type of lpfc_evt_iocb_free to void as it doesn't
1214 return anything.
1215 * Remove unused cmnd_retry_list and in_retry members in struct
1216 lpfcHBA.
1217 * Remove some instances of unneeded casting of kmalloc's return in
1218 lpfc_scsiport.c
1219 * Remove lpfc_linux_attach() and lpfc_linux_detach(). Integrate
1220 them into lpfc_probe_one() and lpfc_release_one() respectively.
1221 * Remove lpfc_num_iocbs, lpfc_num_bufs module parameters
1222 * Remove #defines for NUM_NODES, NUM_BUFS and NUM_IOCBS
1223
1224Changes from 20040515 to 20040526
1225
1226 * Changing version number to 8.0.2.
1227 * Including dma-mapping.h as one of the include headers. Also
1228 rearrange the #include order.
1229 * Make functions static as appropriate.
1230 * queuecommand() will now return SCSI_MLQUEUE_HOST_BUSY instead of
1231 1 to backpressure midlayer.
1232 * Removed function prototypes for lpfc_start_timer() and
1233 lpfc_stop_timer()
1234 * Changed timer support to be inline. Clk_data is now declared
1235 right next to the corresponding timer_list entry so we don't
1236 have to allocate these clk_data dynamically.
1237 * Add readls after writels to PCI space to flush the writes.
1238 * Fix misspelled word "safety" in function names.
1239 * Fix up comments in lpfc.conf for per HBA parameters to reflect
1240 new implementation.
1241 * Change lpfc_proc_info handler to get the Nodename from
1242 fc_nodename and not fc_portname.
1243 * Fix up some comments and whitespace in lpfc_fcp.c.
1244 * Formatting changes: get rid of leading spaces in code
1245 * Move discovery processing from tasklet to a kernel thread.
1246 * Move ndlp node from unmap list to map list if ADISC completed
1247 successfully.
1248 * Flush all the ELS IOCBs when there is a link event.
1249 * LP9802 qdepth is twice the LP9802DC qdepth. Delay
1250 elx_sched_init after READ_CONFIG to get max_xri from the
1251 firmware. Reset ELX_CFG_DFT_HBA_Q_DEPTH to max_xri after
1252 READ_CONFIG
1253 * Fix fc_get_cfg_parm() to be more robust and support embedded hex
1254 values. The lpfc_param's are now defined as:
1255 lpfc_log_verbose="lpfc:0,lpfc0:0x10,lpfc1:4,lpfc100:0xffff" The
1256 "," delimter does not matter. It can be anything or not exist at
1257 all. ie param = "lpfc:0lpfc0:0x10.lpfc1:4txtlpfc100:0xffff" will
1258 also work. Additionally the string is treated as case
1259 insensitive.
1260 * Changed all usage of lpfc_find_lun_device() to lpfc_find_lun().
1261 * Removed unnecessary wrappers lpfc_find_lun_device() and
1262 lpfc_tran_find_lun().

1268 scsi_device->hostdata, which is setup in slave_alloc.
1269 * Eliminate unnecessary checking on every cmd just to see if we
1270 are accessing the device the first time.
1271 * Remove assumption in lpfc_reset_lun_handler that a valid
1272 lpfc_scsi_buf is hung off of linux's scsi_cmnd->host_scribble
1273 when our reset is called.
1274

1299 * Remove no longer needed EXPORT_SYMBOLs
1300 * Remove some unused code (1600 msg's related)
1301
1302Changes from 20040429 to 20040507
1303
1304 * Change version to 8.0.0
1305 * Fix the number of cmd / rsp ring entries in lpfc_fcp.c to match
1306 the divisions setup in lpfc_hw.h.
1307 * Remove phba->iflag reference.
1308 * Several locking improvements.
1309 * Remove functions lpfc_drvr_init_lock, lpfc_drvr_lock,

1311 * Remove LPFC_DRVR_LOCK and LPFC_DRVR_UNLOCK macros.
1312 * Make lpfc_info() use lpfc_get_hba_model_desc() instead of
1313 rewriting almost identical code.
1314 * Fix 1 overly long line in each of lpfc_cfgparm.h, lpfc_ftp.c and
1315 lpfc_sli.c.
1316 * Fix build for Red Hat 2.6.3 kernel by #defining MODULE_VERSION
1317 only if it isn't already defined.
1318 * Change elx_sli_issue_mbox_wait to return correct error code to
1319 the caller.
1320 * In some of the els completion routines, after calling
1321 lpfc_elx_chk_latt, driver ignores the return code of the
1322 lpfc_elx_chk_latt. This will prevent the discovery state machine
1323 restarting correctly when there are link events in the middle of
1324 discovery state machine running. Fix this by exiting discovery
1325 state machine if lpfc_els_chk_latt returns a non zero value.

1327 * Removed unused first_check.
1328 * Remove some unused fields and defines.
1329 * Change lpfc-param names to lpfc_param.

1336 * Remove duplicated prototypes from lpfc_crtn.h:
1337 lpfc_config_port_prep, lpfc_config_port_post,
1338 lpfc_hba_down_prep.
1339 * Removed some unused export_symbols.
1340 * Install driver files into */drivers/scsi/lpfc instead of
1341 */drivers/scsi.
1342
1343Changes from 20040426 to 20040429
1344
1345 * Declared export symbol lpfc_page_alloc and lpfc_page_free

1348 that uses it (lpfc_diag.h).
1349 * Change lpfc_sli_wake_iocb_wait to do a regular wake_up since
1350 lpfc_sli_issue_iocb_wait now sleeps uninterruptible.
1351 * Replace list_for_each() with list_for_each_safe() when a list
1352 element could be deleted.
1353 * Fix IOCB memory leak
1354
1355Changes from 20040416 to 20040426
1356
1357 * Change lpfc_config_port_prep() to interpret word 4 of the DUMP
1358 mbox response as a byte-count
1359 * Add info attribute to sysfs
1360 * Minor formatting (spaces to tabs) cleanup in lpfc_sched.h

1368 * Fix severity inconsistency with log message 249
1369 * Removed lpfc_max_target from lpfc_linux_attach
1370 * Replace references to lpfcDRVR.pHba[] with lpfc_get_phba_by_inst()
1371 * Change lpfc_param to lpfc-param
1372 * Partially removed 32 HBA restriction within driver. Incorported
1373 lpfc_instcnt, lpfc_instance[], and pHba[] into lpfcDRVR
1374 structure Added routines lpfc_get_phba_by_inst()
1375 lpfc_get_inst_by_phba() lpfc_check_valid_phba()
1376 * Turn on attributes "set" & "params" by default.
1377 * Further formatting/whitespace/line length cleanup on: lpfc_ct.c
1378 lpfc_els.c lpfc_fcp.c lpfc_hbadisc.c lpfc_init.c lpfc_ipport.c
1379 lpfc_mbox.c lpfc_nportdisc.c lpfc_sched.c lpfc_sched.h
1380 lpfc_scsi.h lpfc_scsiport.c lpfc_sli.c and lpfc_sli.h
1381 * Add log message 249 to log any unsupported device addressing
1382 modes encountered.
1383 * Add support for 256 targets and 256 LUNs
1384 * Fixed panic in lpfc_linkdown.
1385 * Removed (struct list_head*) casting in several calls to list_del
1386 * Free irq reservation and kill running timers when insmod or

1388 * Remove drivers/scsi from include path
1389 * Wrap use of log message 311 in macro
1390 * Detect failure return from pci_map_sg call in lpfc_os_prep_io
1391 * Fix use-after-free of IOCB in lpfc_sli_process_sol_iocb which
1392 was causing an Oops on 2.6.5 kernel.
1393 * Cleanup use of several gotos not used for error exit.
1394 * Replace memcpy_toio() and memcpy_toio() with endian-dependent
1395 lpfc_memcpy_to_slim() and lpfc_memcpy_from_slim() so that for
1396 big endian hosts like PPC64, the SLIM is accessed 4 bytes at a
1397 time instead of as a byte-stream.
1398
1399Changes from 20040409 to 20040416
1400
1401 * The scsi_register and scsi_alloc_host OS calls can fail and
1402 return a zero-valued host pointer. A ctrl-C on 2.6 kernels
1403 during driver load will cause this and the driver to panic.
1404 Fixed this bug. Also found a bug in the error_x handling with
1405 lpfc_sli_hba_down - it was in the wrong place and the driver
1406 lock was not held, but needed to be (in lpfc_linux_attach) Fixed
1407 both. Did some minor comment clean up.
1408 * Removed unwanted (void *) castings.
1409 * Replace define of INVALID_PHYS, with kernel 2.6.5's
1410 dma_mapping_error() and add a inline function for earlier
1411 kernels. Remove lpfc_bad_scatterlist().
1412 * Clean up formatting in hbaapi.h, lpfc.h, lpfc_cfgparm.h,
1413 lpfc_crtn.h, lpfc_ct.c, lpfc_diag.h, lpfc_disc.h, lpfc_els.c,
1414 lpfc_fcp.c, lpfc_hbadisc.c, lpfc_hw.h, lpfc_init.c,
1415 lpfc_ipport.c, lpfc_logmsg.c, lpfc_logmsg.h and lpfc_scsiport.c
1416 - mostly replacing groups of 8 spaces with hard tabs and keeping
1417 lines to 80 column max..
1418 * Removed LPFC_DRVR_LOCK call from lpfc_unblock_requests for 2.4
1419 kernels. The lpfc_scsi_done routine already unlocks the driver
1420 lock since it expects this lock to be held.
1421 * Removed global lock capabilities from driver lock routines
1422 * Remove SA_INTERRUPT flag from request_irq
1423 * Move dma_addr_t cast inside of getPaddr macro as everywhere
1424 getPaddr is used, the return is cast to dma_addr_t.
1425 * Clean up formatting in lpfc_sli.c and lpfc_sysfs.c - mostly
1426 replacing groups of 8 spaces with hard tabs and keeping lines
1427 to 80 column max.
1428 * Fix build for RHEL 2.1 BOOT kernels by always #including
1429 interrupt.h in lpfc.h.
1430 * Fix RHEL 3 build by #defining EXPORT_SYMTAB.
1431 * Replace sprintf with snprintf in lpfc_proc_info.
1432 * Fix build warnings on 2.6 kernels - remove no longer used calls
1433 to character device initialization.
1434 * Initial support code for discovery in tasklet conversion.
1435 * Removing char interface and ioctl code.
1436 * Change all elx prefixes to lpfc
1437 * Replace lpfc_write_slim() & lpfc_read_slim() with memcpy_toio(),
1438 memcpy_fromio(), writel() & readl().
1439
1440Changes from 20040402 to 20040409
1441
1442 * Replaced lpfc_read_hbaregs_plus_offset and
1443 lpfc_write_hbaregs_plus_offset functions with readl and writel.
1444 * Get rid of long mdelay's in insmod path
1445 * Changed the way our pci_device_id structures are initialized
1446 * Replace lpfc_read/write_CA/HA/HC/HS with calls to readl() &
1447 writel() directly.
1448 * Increase SLI2_SLIM to 16K Increase cmd / rsp IOCBs accordingly
1449 * Removed lpfc_els_chk_latt from the lpfc_config_post function.
1450 lpfc_els_chk_latt will enable the link event interrupts when
1451 flogi is pending which causes two discovery state machines
1452 running parallely.
1453 * Add pci_disable_device to unload path.
1454 * Move lpfc_sleep_event from lpfc_fcp.c to lpfc_util_ioctl.c
1455 * Call dma_map_single() & pci_map_single() directly instead of via
1456 macro lpfc_pci_map(). Allow address 0 for PPC64.
1457 * Change sleep to uninterruptible in lpfc_sli_issue_icob_wait
1458 because this function doesn't handle signals.
1459 * Move lpfc_wakeup_event from lpfc_fcp.c to lpfc_ioctl.c
1460 * Remove unneeded #include <linux/netdevice.h>
1461 * Remove unused clock variables lpfc_clkCnt and lpfc_sec_clk.
1462 * Get rid of capitalization of function names.
1463 * Removed lpfc_addr_sprintf.
1464 * Implemented gotos in lpfc_linux_attach for error cases.
1465 * Replace mlist->dma.list = dmp->dma.list; to mlist = dmp.
1466 * Remove functions lpfc_get_OsNameVersion and elx_wakeup. Change
1467 elx_wakeup to wake_up_interruptible
1468 * Add function lpfc_get_os_nameversion and change
1469 lpfc_get_OsNameVersion to lpfc_get_os_nameversion.
1470 * Remove lpfc_get_OsNameVersion
1471 * Change driver name to a consistent lpfc in every visible place.
1472 * Fix build warning: removed unused variable ret in lpfc_fdmi_tmo.
1473 * Remove lpfc_utsname_nodename_check function
1474 * Remove functions lpfc_register_intr and lpfc_unregister_intr
1475 * Fill in owner field in lpfc_ops file_operations struct and
1476 remove now unnecessary open and close entry points.
1477 * Change function name prefixes from elx_ to lpfc_
1478 * Remove special case check for TUR in elx_os_prep_io()
1479 * Renamed elx_scsi.h to lpfc_scsi.h
1480 * Renamed elx_sched.h to lpfc_sched.h
1481 * Renamed elx_mem.h to lpfc_mem.h
1482 * Renamed elx_sli.h to lpfc_sli.h
1483 * Renamed elx_logmsg.h to lpfc_logmsg.h
1484 * Renamed elx.h to lpfc.h
1485 * Renamed elx_sli.c to lpfc_sli.c
1486 * Renamed elx_sched.c to lpfc_sched.c
1487 * Renamed elx_mem.c to lpfc_mem.c
1488 * Renamed elx_logmsg.c to lpfc_logmsg.c
1489 * Renamed lpfcLINUXfcp.c lpfc_fcp.c
1490 * Renamed elx_clock.c to lpfc_clock.c
1491 * Reduce stack usage in lpfc_info().
1492 * Move lpip_stats structure from lpfc_hba.h to lpfc_ip.h.
1493 * Move lpfc_stats and HBAEVT_t structures from lpfc_hba.h to
1494 lpfc.h
1495 * Remove lpfc_hba.h
1496 * Remove duplicate rc definitions from
1497 * Removed code which used next pointer to store mbox structure.
1498 * Cleaned up list iterations.
1499 * Removed non list manipulation of the next pointers.
1500 * Change list_del()/INIT_LIST_HEAD sequences to list_del_init()
1501 * In ELX_IOCBQ_t: Moved hipri_trigger field to iocb_flag. Combined
1502 hipri_wait_queue and rsp_iocb in union
1503 * Replaced casting from list_head with list_entry macro.
1504 * Added ct_ndlp_context field to the ELX_IOCBQ_t.
1505 * Do not use DMABUf_t list to store ndlp context
1506 * Return 0 from lpfc_process_iotcl_util() when ELX_INITBRDS
1507 succeeds.
1508 * remove elx_os_scsiport.h
1509 * Do not use DMABUf_t list to hold rpi context
1510 * Replace elx_cfg_* names with lpfc_cfg-*
1511 * Moved FCP activity to ring 0. Moved ELS/CT activity to ring 2.
1512 * Clean up formatting of elx_sli.h (tabs for indents, 80 column
1513 lines).
1514 * Remove unused elxclock declaration in elx_sli.h.
1515 * Since everywhere IOCB_ENTRY is used, the return value is cast,
1516 move the cast into the macro.
1517 * Split ioctls out into seperate files
1518
1519Changes from 20040326 to 20040402
1520
1521 * Updated ChangeLog for 20040402 SourceForge drop.
1522 * Use safe list iterator for ndlp list
1523 * Added code to return NLP_STE_FREED_NODE from the discovery
1524 state machine functions if the node is freed from the
1525 function.
1526 * Fixes to DMABUF_t handling
1527 * Fix for load error in discovery
1528 * Remove loop_cnt variable from lpfc_rcv_plogi_unused_node.

1530 * Remove support for building 2.4 drivers
1531 * Remove elx_util.h and replace elx_disc.h with lpfc_disc.h
1532 * Implemented the Linux list macros in the discovery code.
1533 Also moved elx_disc.h contents into lpfc_disc.h
1534 * Unused variable cleanup
1535 * Use Linux list macros for DMABUF_t
1536 * Break up ioctls into 3 sections, dfc, util, hbaapi
1537 rearranged code so this could be easily seperated into a
1538 differnet module later All 3 are currently turned on by
1539 defines in lpfc_ioctl.c LPFC_DFC_IOCTL, LPFC_UTIL_IOCTL,
1540 LPFC_HBAAPI_IOCTL
1541 * Misc cleanup: some goto's; add comments; clarify function
1542 args
1543 * Added code to use list macro for ELXSCSITARGET_t.
1544 * New list implementation for ELX_MBOXQ_t
1545 * Cleaned up some list_head casting.
1546 * Put IPFC ifdef around two members of struct lpfc_nodelist.
1547 * Cleaned up iocb list using list macros and list_head data
1548 structure.
1549 * lpfc_online() was missing some timer routines that were
1550 started by lpfc_linux_attach(). These routines are now also
1551 started by lpfc_online(). lpfc_offline() only stopped
1552 els_timeout routine. It now stops all timeout routines
1553 associated with that hba.
1554 * Replace seperate next and prev pointers in struct
1555 lpfc_bindlist with list_head type. In elxHBA_t, replace
1556 fc_nlpbind_start and _end with fc_nlpbind_list and use
1557 list_head macros to access it.
1558 * Fix ulpStatus for aborting I/Os overlaps with newer firmware
1559 ulpStatus values
1560 * Rework params_show/store to be consistent as the other

1564 * Ifdef Scheduler specific routines
1565 * Removed following ununsed ioclt's: ELX_READ_IOCB
1566 ELX_READ_MEMSEG ELX_READ_BINFO ELX_READ_EINVAL ELX_READ_LHBA
1567 ELX_READ_LXHBA ELX_SET ELX_DBG LPFC_TRACE
1568 * Removed variable fc_dbg_flg
1569 * Fixed a bug where HBA_Q_DEPTH was set incorrectly for
1570 3-digit HBAs. Also changed can_queue so midlayer will only
1571 send (HBA_Q_DEPTH - 10) cmds.
1572 * Clean up code in the error path, check condition. Remove
1573 ununsed sense-related fields in lun structure.
1574 * Added code for safety pools for following objects: mbuf/bpl,
1575 mbox, iocb, ndlp, bind
1576 * Wrapped '#include <elx_sched.h>' in '#ifdef USE_SCHEDULER'.
1577 * Fixed 'make clean' target.
1578 * Build now ignores elx_sched.o, and includes lpfc_sysfs.o.
1579 * Wrapped lpfndd.o target in BUILD_IPFC ifdef.
1580 * Removed elx_os.h inclusion in implementation files.
1581 * Removed ELX_OS_IO_t data structure and put data direction
1582 and non scatter/gather physical address into the scsi buffer
1583 structure directly. Moved DRVR_LOCK, putPaddr, getPaddr
1584 macros and some defines into elx.h since they are required
1585 by the whole driver.
1586 * Migrated following ioctls (debug) ELX_DISPLAY_PCI_ALL
1587 ELX_DEVP ELX_READ_BPLIST ELX_RESET_QDEPTH ELX_STAT.
1588 * Step 1 of attempt to move all Debug ioctls to sysfs.
1589 Implemented the following IOCTLs in sysfs: ELX_WRITE_HC
1590 ELX_WRITE_HS ELX_WRITE_HA ELX_WRITE_CA ELX_READ_HC
1591 ELX_READ_HS ELX_READ_HA ELX_READ_CA ELX_READ_MB ELX_RESET
1592 ELX_READ_HBA ELX_INSTANCE ELX_LIP. Also introduced
1593 attribute "set" to be used in conjuction with the above
1594 attributes.
1595 * Removed DLINK, enque and deque declarations now that clock
1596 doesn't use them anymore
1597 * Separated install rule so that BUILD_IPFC has to be set when
1598 make is called in order for the install rule to attempt to
1599 copy the lpfndd.o driver. This change fixes a bug that
1600 occurs because the install rule by default attempted to
1601 install lpfndd.o, whereas the default make rule did not by
1602 default build lpfndd.o.
1603 * Keep track if hbaapi index numbers need to be refreshed.
1604 * Removed prod_os.h from include list.
1605 * Removed LPFC_LOCK and LPFC_UNLOCK macros. Added OS calls
1606 into elx_os_scsiport.c. This file is now empty.
1607 * Added spin_lock_irqsave and spin_unlock_irqrestore calls
1608 into code directly and removed LPFC_LOCK_ and _UNLOCK_
1609 macros
1610 * Remove references to "elx_clock.h"
1611 * Added utsname.h to include list. The previous checkin to
1612 elx_os.h removed its inclusion of utsname.h since there is
1613 precious little in the file. However, lpfcLINUXfcp.c needs
1614 it and now has it.
1615 * Removed some commented-out code
1616 * Removed elx_lck_t data structure, stray elxDRVR_t type, and
1617 include from file. No longer used.
1618 * Removed two PCI Sync defines. Removed includes - not
1619 needed. Cleaned up macro lines.
1620 * Added two functions from elxLINUXfcp.c. These functions
1621 were IPFC specific.
1622 * Removed hipri lock abstractions and added OS call into code.
1623 Removed elx_lck_t and added spinlock_t directly. Moved two
1624 IPFC functions into lpfc_ipport.c
1625 * Moved IP specific structures to lpfc_ip.h file.
1626 * lpfc_ipfarp_timeout() uses system timer. Remove all usages
1627 of old internal clock support.
1628 * Made changes to compile without IPFC support for the default
1629 build. Added ifdef IPFC for all lpfc_ip.h includes.
1630 * Patched elx_free_scsi_buf
1631 * Removed elx_sched.o from 2.6 dependencies
1632 * Reworked lpfc_pcimap.
1633 * Use Linux swap macros to replace ELX swapping macros
1634 (SWAP_SHORT, SWAP_LONG, SWAP_DATA, SWAP_DATA16,
1635 PCIMEM_SHORT, PCIMEM_LONG, PCIMEM_DATA).
1636 * move in_interrupt() check inside of elx_sleep_ms()
1637 * Moved location of pci.h include.
1638 * Restored elx_lck_t types in elxHBA_t.
1639 * Removed elx_pci_dma_sync call. Also removed some PCI
1640 defines from elx_hw.h and removed the spinlock_t locks that
1641 are no longer used in elx.h
1642 * elx_iodone() now uses system timer.
1643 * elx_qfull_retry() now uses system timer.
1644 * lpfc_put_buf(), lpfc_ip_xri_timeout() and
1645 lpfc_ip_timeout_handler() now use system timer.
1646 * lpfc_fdmi_tmo() and lpfc_qthrottle_up() now use system
1647 timer.
1648 * Removed num_bufs and num_iocbs configuration parameters.
1649 * Fixed a memory corruption bug. This was caused by a memory
