dea3101e | 1 | Known issues : |
2 | * Please read the associated RELEASE-NOTES file !!! | |
3 | * This source release intended for upstream kernel releases only! | |
4 | ||
5 | Changes 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 | ||
47 | Changes 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 | ||
79 | Changes 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 | ||
98 | Changes 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 | ||
141 | Changes 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 | ||
169 | Changes 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 | ||
213 | Changes 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 | ||
276 | Changes 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 | ||
319 | Changes 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 | |
25985edc | 355 | freed (after nodev tmo). This bug was causing i/o received in |
dea3101e | 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 | ||
363 | Changes 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 | ||
396 | Changes 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 | ||
425 | Changes 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 | ||
455 | Changes 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 | ||
466 | Changes 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 | ||
483 | Changes 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. | |
25985edc | 533 | * Modified lpfc_free_scsi_buf to accommodate all three scsi_buf |
dea3101e | 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 | |
b595076a | 576 | the time the host structure was initialized. lpfc_cfg_params |
dea3101e | 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)". | |
25985edc | 586 | * Fixnode was losing starget when rediscovered. We saw messages |
dea3101e | 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. | |
25985edc | 607 | * Remove an unnecessary list_del() in lpfc_hbadisc.c. |
dea3101e | 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 | ||
620 | Changes 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 | |
a33f3224 | 710 | gone - lpfc_sli_issue_iocb_wait loses its flags argument |
dea3101e | 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 | |
025dfdaf | 736 | to nothing more than the lpfc_nodelist pointer. |
dea3101e | 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 | ||
751 | Changes 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. | |
25985edc | 756 | * Changes to accommodate rnid. |
dea3101e | 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, | |
a7ce2e0d | 810 | it handles the empty list case just fine and the additional |
dea3101e | 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. | |
25985edc | 816 | * Removed unused prototypes from lpfc_crtn.h - |
dea3101e | 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 | ||
851 | Changes 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. | |
25985edc | 866 | * Changed 2 occurrences of if( 1 != f(x)) to if(f(x) != 1) |
dea3101e | 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 | ||
887 | Changes 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 | ||
908 | Changes 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 | ||
926 | Changes from 20040723 to 20040730 | |
927 | ||
928 | * Changed version number to 8.0.8 | |
929 | * Removed unused LPFN_DRIVER_VERSION #define. | |
930 | * Folded lpfc_findnode_scsiid into lpfc_find_target, its only | |
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 | ||
958 | Changes 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 | ||
979 | Changes 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. | |
3ad2f3fb DM |
992 | * Clock changes: separate nodev_tmo and els_retry_delay into 2 |
993 | separate timers and convert to 1 argument changed | |
dea3101e | 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 | ||
1000 | Changes from 20040614 to 20040709 | |
1001 | ||
1002 | * Changed version number to 8.0.5 | |
1003 | * Make lpfc_info static. | |
1004 | * Make lpfc_get_scsi_buf static. | |
1005 | * Print a warning if pci_set_mwi returns an error. | |
1006 | * Changed SERV_PARM to struct serv_parm. | |
1007 | * Changed LS_RJT to struct ls_rjt. | |
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. | |
1028 | * Remove the need for buf_tmo. | |
1029 | * Changed ULP_BDE64 to struct ulp_bde64. | |
1030 | * Changed ULP_BDE to struct ulp_bde. | |
a33f3224 | 1031 | * Cleanup lpfc_os_return_scsi_cmd() and its call path. |
dea3101e | 1032 | * Removed lpfc_no_device_delay. |
1033 | * Consolidating lpfc_hba_put_event() into lpfc_put_event(). | |
1034 | * Removed following attributes and their functionality: | |
1035 | lpfc_extra_io_tmo, lpfc_nodev_holdio, lpfc_delay_rsp_err, | |
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 | ||
1110 | Changes 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 | ||
1156 | Changes 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 | ||
1224 | Changes 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(). | |
1263 | * Switch from using internal bus/id/lun to similar data from | |
1264 | scsi_device structure. | |
1265 | * Eliminate one-line function lpfc_find_target() | |
1266 | * Added slave_alloc, slave_destory | |
1267 | * lpfc_scsi_cmd_start can now acquire lun pointer from | |
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 | ||
1275 | Changes from 20040507 to 20040515 | |
1276 | ||
1277 | * Changed version to 8.0.1 | |
1278 | * Fixed crash on driver rmmod after error injection tests and | |
1279 | lpfc_tasklet deadlock. | |
1280 | * Modified lpfc.conf to remove limit on number of support hosts | |
1281 | * Removed HBAAPI | |
1282 | * Removed duplication of SCSI opcodes from lpfc_fcp.h that are | |
1283 | available in scsi/scsi.h | |
1284 | * Rework module_param usage | |
1285 | * Added MODULE_PARAM_DESC for various module_params | |
1286 | * Removed #define EXPORT_SYMTAB | |
1287 | * Removed #includes of if_arp.h and rtnetlink.h | |
1288 | * Removed string "Open Source" from MODULE_DESC | |
1289 | * Cleanup duplicated string definitions used by MODULE_DESC | |
1290 | * Renamed lpfc_pci_[detect|release] to lpfc_pci_[probe|remove]_one | |
1291 | * Fix formatting of lpfc_driver | |
1292 | * Remove unnecessary memset to 0 of lpfcDRVR | |
1293 | * Attach driver attributes always unless pci_module_init failed | |
1294 | * Remove all one-line wrappers from lpfc_mem. | |
1295 | * Remove lpfc_sysfs_set_[show|store] as it is no longer needed | |
1296 | * Redo lpfc_sysfs_params_[show|store] to one value per attribute rule | |
1297 | * Breakdown lpfc_sysfs_info_show into smaller one value per attribute | |
1298 | * Use device attributes instead of driver attributes where appropriate | |
1299 | * Remove no longer needed EXPORT_SYMBOLs | |
1300 | * Remove some unused code (1600 msg's related) | |
1301 | ||
1302 | Changes 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, | |
1310 | lpfc_drvr_unlock and lpfc_hipri_*. | |
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. | |
1326 | * Removed MAX_LPFC_BRDS from lpfc_diag.h | |
1327 | * Removed unused first_check. | |
1328 | * Remove some unused fields and defines. | |
1329 | * Change lpfc-param names to lpfc_param. | |
1330 | * Add use of MODULE_VERSION macro for 2.6 kernels. | |
1331 | * Shorten length of some of the comment lines to make them more | |
1332 | readable. | |
1333 | * Move FCP_* definitions to their own header file, lpfc_fcp.h. | |
1334 | * Remove unused prototypes from lpfc_crtn.h: fcptst, iptst, | |
1335 | lpfc_DELAYMS. | |
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 | ||
1343 | Changes from 20040426 to 20040429 | |
1344 | ||
1345 | * Declared export symbol lpfc_page_alloc and lpfc_page_free | |
1346 | * Changed lpfc version number to 6.98.3 | |
1347 | * Move the definition of MAX_LPFC_BRDS to the only header file | |
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 | ||
1355 | Changes 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 | |
1361 | * Remove unused log message number 732 | |
1362 | * Completing MODULE_PARM -> module_param changes | |
1363 | * Removed unused targetenable module parameter | |
1364 | * Removed locks from lpfc_sli_issue_mbox_wait routine | |
1365 | * Removed code that retry 29,00 check condition | |
1366 | * Removed code that manipulates rspSnsLen. | |
1367 | * Fix use of lun-q-depth config param | |
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 | |
1387 | modprobe are killed via ctrl-c | |
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 | ||
1399 | Changes 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 | ||
1440 | Changes 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 | |

dea3101e | 1518 | |
1519 | Changes 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. | |
1529 | * Remove nle. reference. | |
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 | |
3ad2f3fb | 1537 | rearranged code so this could be easily separated into a |
dea3101e | 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. | |
3ad2f3fb | 1554 | * Replace separate next and prev pointers in struct |
dea3101e | 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 | |
1561 | routines. Remove generic'ness and rely on set attribute. | |
1562 | * Remove unused log message. | |
1563 | * Collapse elx_crtn.h and prod_crtn.h into lpfc_crtn.h | |
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 | |
25985edc | 1593 | attribute "set" to be used in conjunction with the above |
dea3101e | 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 | |
1650 | write to ndlp structure from lpfc_cmpl_els_acc function. | |
1651 | This ndlp structure was freed from lpfc_els_unsol_event. | |
1652 | * lpfc_disc_timeout() and lpfc_establish_link_tmo() now use | |
1653 | system timer. Also update lpfc_els_retry_delay() to do a | |
1654 | single lock release at the end. | |
1655 | * Remove use of PAN (pseudo adapter number). | |
1656 | * Reintroduced usage of the cross compiler for building on | |
1657 | ppc64 to remove build errors that were cropping up when | |
1658 | using the standard gcc compiler. | |
1659 | * Fix no-unlock-before return in lpfc_els_retry_delay which was | |
1660 | causing a deadlock on insmod in some environments. | |
1661 | * Minor format changes fix up comments | |
1662 | * Create utility clock function elx_start_timer() and | |
1663 | elx_stop_timer(). All timeout routines now use these common | |
1664 | routines. | |

1671 | declaration. | |
1672 | * Cleanup casting around DMA masks. | |
1673 | * Comment out lpfndd.o modules_install section as lpfndd.o is | |
1674 | not generated if CONFIG_NET_LPFC is not set. Also refer to | |
1675 | BASEINCLUDE only in out of kernel source module builds as it | |
1676 | will not exist otherwise. | |
1677 | * Removed unused malloc counters from lpfcLINUXfcp.c. | |
1678 | * Remove some unnecessary #includes in lpfcLINUXfcp.c | |

1688 | kernel compile. Does not recompile all files on every | |
1689 | build. Uses the kernel build's definitions of CFLAGS, | |
1690 | MODFLAGS etc. Removed "make rpm" option. | |
1691 | * Removed unused #defines CLOSED, DEAD, OPENED, NORMAL_OPEN | |
1692 | and unneeded #include of elx_sched.h in elx.h. | |

1786 | * Cleaned up some memory pool implementation code. | |
1787 | * Fix panic with char dev changes. Turns out that 2.6.4 code does | |
1788 | the same in kernel space with the 2.4 interface style | |
1789 | definitions. So remove the new char dev code altogether. | |
1790 | * Remove typecasting from fc_get_cfg_param and consolidate | |
1791 | multiple instances of the parameter switch into a single | |
1792 | instance. | |
1793 | * Use lpfc_is_LC_HBA() macro that tests pcidev->device directly | |
1794 | instead of saving a private copy that undergoes varied shifting | |
1795 | & casting. | |
1796 | * Removed usage of all memory pools. | |

1803 | * Change void *pOScmd to struct sk_buff *pCmd | |
1804 | * Remove data directon code. | |
1805 | * Removed memory pool for buf/bpl buffers and use kmalloc/kfree | |
1806 | pci_pool_alloc/free directly. | |
1807 | * Move PPC check for DMA address 0 in scatter-gather list, into | |
1808 | lpfc_compat.h | |

1810 | * Clean up the 2.6 vs 2.4 #if blocks. | |
1811 | * Conditionalize Scheduler | |
1812 | * Add a comment to explain a little what the first Makefile | |
1813 | section does. | |
1814 | * Removed lpfc_intr_post | |
1815 | * Sysfs new display format. Also added write functionality. You | |
1816 | can [ echo "0 log_verbose 3" > | |
1817 | /sys/bus/pci/drivers/lpfc/params]. Hex support yet to be added. | |
1818 | * Removed several #ifdef powerpc, including for a discovery issue | |
1819 | in lpfc_ValidLun() | |
1820 | * Change elx_printf_log to use vsprintf. | |
1821 | * Added lpfc_compat.h provides macros to aid compilation in the | |
1822 | Linux 2.4 kernel over various platform architectures. Initially | |
1823 | support mapping to a DMA address. | |
1824 | * Removed memory pool for nlp/bind buffers and use kmalloc/kfree | |
1825 | directly. | |
1826 | * Removed memory pool for iocb buffers and use kmalloc/kfree | |
1827 | directly. | |
1828 | * Removed memory pool for mailbox buffers and use kmalloc/kfree | |
1829 | directly. | |
1830 | * Cleaned up back and forth casts | |
1831 | * Initial support for sysfs for 2.6 kernel. | |
1832 | * Changed elx_dma_addr_t to dma_addr_t | |
1833 | * Fix a 2.6 kernel check to be >= 2.6.0 instead of > (was missing | |
1834 | 2.6.0). | |
1835 | * Remove elx_printf and elx_str_sprintf. Replace elx_print with | |
1836 | printk. | |
1837 | * Replace elx_printf with printk. | |
1838 | * Replace elx_str_sprintf with sprintf. | |
1839 | * Removed the mem_lock, its prototype, function, macro, and | |
1840 | iflags. | |
1841 | * Use kmalloc/kfree for ELX_SCSI_BUF_t | |
1842 | * Use linux pci_pools for SCSI_DMA_EXT | |
1843 | * Use linux pci_pools for BPLs. | |
1844 | * Minor cleanup of DFC args for PPC64. | |
1845 | * Several small indentation cleanups. | |
1846 | * New Linux 2.6 style of char device registration. | |
1847 | * Migrated members of LPFCHBA_t and LINUX_HBA_t into elxHBA_t | |
1848 | * Use strcpy, strncmp, isdigit, strlen instead of abstractions | |
1849 | * Cleanup of driver_template. | |
1850 | * Facilitate compile time turn on/off of lpfc_network_on. | |
1851 | * Split large source files into smaller, better named ones. | |
