|
* Please read the associated RELEASE-NOTES file !!! |
|
* This source release intended for upstream kernel releases only! |
|
|
|
Changes from 20050323 to 20050413 |
|
|
|
* Changed version number to 8.0.28 |
|
* Fixed build warning for 2.6.12-rc2 kernels: mempool_alloc now |
|
requires a function which takes an unsigned int for gfp_flags. |
|
* Removed pci dma sync calls to coherent/consistent pci memory. |
|
* Merged patch from Christoph Hellwig <[email protected]>: split helpers |
|
for fabric and nport logins out of lpfc_cmpl_els_flogi. |
|
* Removed sysfs attributes that are used to dump the various |
|
discovery lists. |
|
* Fix for issue where not all luns are seen. Search all lists |
|
other than unmap list in lpfc_find_target(). Otherwise INQUIRY |
|
to luns on nodes in NPR or other relevant states (PLOGI, |
|
PRLI...) are errored back and scan() terminates. |
|
* Removed FC_TRANSPORT_PATCHESxxx defines. They're in 2.6.12-rc1. |
|
* Compare return value of lpfc_scsi_tgt_reset against SCSI |
|
midlayer codes SUCCESS/FAILED which that function returns rather |
|
than SLI return code. |
|
* Removed extraneous calls to lpfc_sli_next_iotag which should |
|
only be called from lpfc_sli_submit_iocb. Also make |
|
lpfc_sli_next_iotag static. |
|
* Added PCI ID for LP10000-S. |
|
* Changes in lpfc_abort_handler(): Return SUCCESS if we did not |
|
find command in both TX and TX completion queues. Return ERROR |
|
if we timed out waiting for command to complete after abort was |
|
issued. |
|
* Zero-out response sense length in lpfc_scsi_prep_cmnd to prevent |
|
interpretation of stale sense length when the command completes |
|
- was causing spurious 0710 messages. |
|
* Moved clearing of host_scribble inside host_lock in IO |
|
completion path. |
|
* Fixed a bunch of mixed tab/space indentation. |
|
* Allow hex format numbers in sysfs attribute setting. Fix |
|
application hang when invalid numbers are used in sysfs |
|
settings. |
|
* Removed extra iotag allocation by lpfc_abort_handler. |
|
* Clear host_scribble in the scsi_cmnd structure when failing in |
|
queuecommand. |
|
* Changed logic at top of lpfc_abort_handler so that if the |
|
command's host_scibble field is NULL, return SUCCESS because the |
|
driver has already returned the command to the midlayer. |
|
|
|
Changes from 20050308 to 20050323 |
|
|
|
* Changed version number to 8.0.27 |
|
* Changed a few lines from patch submitted by Christoph Hellwig |
|
(3/19). MAILBOX_WSIZE * (uint32_t) is replaced with an |
|
equivalent MAILBOX_CMDSIZE macro. |
|
* Merged patch from Christoph Hellwig (3/19): some misc patches |
|
against the latest drivers: |
|
- stop using volatile. if you need special ordering use memory |
|
barriers but that doesn't seem to be the case here |
|
- switch lpfc_sli_pcimem_bcopy to take void * arguments. |
|
- remove typecast for constants - a U postfix marks them |
|
unsigned int in C |
|
- add a MAILBOX_CMD_SIZE macro, as most users of |
|
MAILBOX_CMD_WSIZE didn't really want the word count |
|
- kill struct lpfc_scsi_dma_buf and embedded the two members |
|
directly in struct lpfc_scsi_buf |
|
- don't call dma_sync function on allocations from |
|
pci_pool_alloc - it's only for streaming mappings (pci_map_*) |
|
* Merged patch from Christoph Hellwig (3/19) - nlp_failMask isn't |
|
ever used by the driver, just reported to userspace (and that in |
|
a multi-value file which is against the sysfs guidelines). |
|
* Change pci_module_init to pci_register_module() with appropriate |
|
ifdefs. |
|
* Added #include <linux/dma-mapping.h> as required by the DMA |
|
32bit and 64bit defines on some archs. |
|
* Merged patch from Christoph Hellwig (03/19) - fix initialization |
|
order - scsi_add_host must happen last from scsi POV. Also some |
|
minor style/comment fixups. |
|
* Fixed use of TRANSPORT_PATCHES_V2 by changing to |
|
FC_TRANSPORT_PATCHES_V2. |
|
|
|
Changes from 20050223 to 20050308 |
|
|
|
* Changed version number to 8.0.26 |
|
* Revise TRANSPORT_PATCHES_V2 so that lpfc_target is removed and |
|
rport data is used instead. Removed device_queue_hash[]. |
|
* Changed RW attributes of scan_down, max_luns and fcp_bind_method |
|
to R only. |
|
* Fixed RSCN handling during initial link initialization. |
|
* Fixed issue with receiving PLOGI handling when node is on NPR |
|
list and marked for ADISC. |
|
* Fixed RSCN timeout issues. |
|
* Reduced severity of "SCSI layer issued abort device" message to |
|
KERN_WARNING. |
|
* Feedback from Christoph Hellwig (on 2/5) - In the LPFC_EVT_SCAN |
|
case the caller already has the target ID handly, so pass that |
|
one in evt_arg1. |
|
* Fix compile warning/resultant panic in |
|
lpfc_register_remote_port(). |
|
|
|
Changes from 20050215 to 20050223 |
|
|
|
* Changed version number to 8.0.25 |
|
* Add appropriate comments to lpfc_sli.c. |
|
* Use DMA_64BIT_MASK and DMA_32BIT_MASK defines instead of |
|
0xffffffffffffffffULL & 0xffffffffULL respectively. Use pci |
|
equivalents instead of dma_set_mask and also modify condition |
|
clause to actually exit on error condition. |
|
* Restart els timeout handler only if txcmplq_cnt. On submission, |
|
mod_timer the els_tmofunc. This prevents the worker thread from |
|
waking up the els_tmo handler un-necessarily. The thread was |
|
being woken up even when there were no pending els commands. |
|
* Added new typedefs for abort and reset functions. |
|
* Collapsed lpfc_sli_abort_iocb_xxx into a single function. |
|
* Collapsed lpfc_sli_sum_iocb_xxx into a single function. |
|
* Removed TXQ from all abort and reset handlers since it is never |
|
used. |
|
* Fixed Oops panic in 8.0.23 (reported on SourceForge). The |
|
driver was not handling LPFC_IO_POLL cases correctly in |
|
fast_ring_event and was setting the tgt_reset timeout to 0 in |
|
lpfc_reset_bus_handler. This 0 timeout would not allow the FW |
|
to timeout ABTS's on bad targets and allow the driver to have an |
|
iocb on two lists. Also split the lpfc_sli_ringtxcmpl_get |
|
function into two routines to match the fast and slow completion |
|
semantics - ELS completions worked for the wrong reasons. Also |
|
provided new log message number - had two 0326 entries. |
|
* Removed unused #define LPFC_SCSI_INITIAL_BPL_SIZE. |
|
* Removed unused struct lpfc_node_farp_pend definition. |
|
* Removed unused #define LPFC_SLIM2_PAGE_AREA. |
|
* Changed zeros used as pointers to NULL. |
|
* Removed unneeded braces around single line in lpfc_do_work. |
|
* Close humongous memory leak in lpfc_sli.c - driver was losing 13 |
|
iocbq structures per LIP. |
|
* Removed last of GFP_ATOMIC allocations. |
|
* Locks are not taken outside of nportdisc, hbadisc, els and most |
|
of the init, sli, mbox and ct groups of functions |
|
* Fix comment for lpfc_sli_iocb_cmd_type to fit within 80 columns. |
|
* Replaced wait_event() with wait_event_interruptible(). |
|
wait_event() puts the woker thread in an UNINTERRUPTIBLE state |
|
causing it to figure in load average calculations. Also add a |
|
BUG_ON to the ret code of wait_event_interruptible() since the |
|
premise is that the worker thread is signal-immune. |
|
|
|
Changes from 20050208 to 20050215 |
|
|
|
* Changed version number to 8.0.24 |
|
* Fixed a memory leak of iocbq structure. For ELS solicited iocbs |
|
sli layer now frees the response iocbs after processing it. |
|
* Closed large memory leak -- we were losing 13 iocbq structures |
|
per LIP. |
|
* Changing EIO and ENOMEM to -EIO and -ENOMEM respectively. |
|
* Cleanup of lpfc_sli_iocb_cmd_type array and typing of iocb type. |
|
* Implemented Christoph Hellwig's feedback from 02/05: Remove |
|
macros putLunHigh, putLunLow. Use lpfc_put_lun() inline instead. |
|
* Integrated Christoph Hellwig's feedback from 02/05: Instead of |
|
cpu_to_be32(), use swab16((uint16_t)lun). This is the same as |
|
"swab16() on LE" and "<<16 on BE". |
|
* Added updates for revised FC remote port patch (dev_loss_tmo |
|
moved to rport, hostdata renamed dd_data, add fc_remote_host() |
|
on shutdown). |
|
* Removed unnecessary function prototype. |
|
* Added code to prevent waking up worker thread after the exit of |
|
worker thread. Fixes panic seen with insmod/rmmod testing with |
|
70 disks. |
|
* Integrated Christoph Hellwig's patch from 1/30: Make some |
|
variables/code static (namely lpfcAlpaArray and |
|
process_nodev_timeout()). |
|
* Integrated Christoph Hellwig's patch from 1/30: Use |
|
switch...case instead of if...else if...else if while decoding |
|
JDEC id. |
|
|
|
Changes from 20050201 to 20050208 |
|
|
|
* Changed version number to 8.0.23 |
|
* Make lpfc_work_done, lpfc_get_scsi_buf, |
|
lpfc_mbx_process_link_up, lpfc_mbx_issue_link_down and |
|
lpfc_sli_chipset_init static. |
|
* Cleaned up references to list_head->next field in the driver. |
|
* Replaced lpfc_discq_post_event with lpfc_workq_post_event. |
|
* Implmented Christoph Hellwig's review from 2/5: Check for return |
|
values of kmalloc. |
|
* Integrated Christoph Hellwig's patch from 1/30: Protecting |
|
scan_tmo and friends in !FC_TRANSPORT_PATCHES_V2 && |
|
!USE_SCAN_TARGET. |
|
* Integrated Christoph Hellwig's patch from 1/30: Some fixes in |
|
the evt handling area. |
|
* Integrated Christoph Hellwig's patch from 1/30: Remove usage of |
|
intr_inited variable. The interrupt initilization from OS side |
|
now happens in lpfc_probe_one(). |
|
* Integrated Christoph Hellwig's patch from 1/30: remove shim |
|
lpfc_alloc_transport_attr - remove shim lpfc_alloc_shost_attrs - |
|
remove shim lpfc_scsi_host_init - allocate phba mem in scsi's |
|
hostdata readjust code so that they are no use after free's |
|
(don't use after scsi_host_put) - make lpfc_alloc_sysfs_attr |
|
return errors |
|
* Fixed panic in lpfc_probe_one(). Do not delete in a list |
|
iterator that is not safe. |
|
* Clean up fast lookup array of the fcp_ring when aborting iocbs. |
|
* Following timeout handlers moved to the lpfc worker thread: |
|
lpfc_disc_timeout, lpfc_els_timeout, lpfc_mbox, lpfc_fdmi_tmo, |
|
lpfc_nodev_timeout, lpfc_els_retry_delay. |
|
* Removed unused NLP_NS_NODE #define. |
|
* Integrated Christoph Hellwig's patch from 1/30: remove unused |
|
lpfc_hba_list; remove unused lpfc_rdrev_wd30; remove |
|
lpfc_get_brd_no and use Linux provided IDR. |
|
* Changed board reset procedure so that lpfc_sli_send_reset() |
|
writes the INITFF bit and leaves lpfc_sli_brdreset() to clear |
|
the bit. |
|
* Removed outfcpio sysfs device attribute. |
|
* VPD changes: 1) Modify driver to use the model name and |
|
description from the VPD data if it exists 2) Rework use of DUMP |
|
mailbox command to support HBAs with 256 bytes of SLIM. |
|
* Fixed compile error for implicit definition of struct |
|
scsi_target |
|
|
|
Changes from 20050124 to 20050201 |
|
|
|
* Changed version number to 8.0.22 |
|
* Moved discovery timeout handler to worker thread. There are |
|
function calls in this function which are not safe to call from |
|
HW interrupt context. |
|
* Removed free_irq from the error path of HBA initialization. |
|
This will fix the free of uninitialised IRQ when config_port |
|
fails. |
|
* Make sure function which processes unsolicited IOCBs on ELS ring |
|
still is called with the lock held. |
|
* Clear LA bit from work_ha when we are not supposed to handle LA. |
|
* Fix double locking bug in the error handling part of |
|
lpfc_mbx_cmpl_read_la. |
|
* Implemented fast IOCB processing for FCP ring. |
|
* Since mboxes are now unconditionally allocated outside of the |
|
lock, free them in cases where they are not used. |
|
* Moved out a couple of GFP_ATOMICs in lpfc_disc_timeout, to |
|
before locks so that they can GFP_KERNEL instead. Also cleaned |
|
up code. |
|
* Collapsed interrupt handling code into one function. |
|
* Removed event posting and handling of solicited and unsolicited |
|
iocbs. |
|
* Remove ELS ring handling leftovers from the lpfc_sli_inter(). |
|
* ELS ring (any slow ring) moved from the lpfc_sli_inter() into a |
|
worker thread. Link Attention, Mbox Attention, and Error |
|
Attention, as well as slow rings' attention is passed to the |
|
worker thread via worker thread copy of Host Attention |
|
register. Corresponding events are removed from the event queue |
|
handling. |
|
* Add entries to hba structure to delegate some functionality from |
|
the lpfc_sli_inter() to a worker thread. |
|
* Reduced used of GFP_ATOMIC for memory allocations. |
|
* Moved locks deeper in order to change GFP_ATOMIC to GFP_KERNEL. |
|
* IOCB initialization fix for Raw IO. |
|
* Removed qcmdcnt, iodonecnt, errcnt from lpfc_target and from |
|
driver. |
|
* Added call to lpfc_els_abort in lpfc_free_node. Modified |
|
lpfc_els_abort to reset txq and txcmplq iterator after a |
|
iocb_cmpl call. |
|
* Fixed a use after free issue in lpfc_init.c. |
|
* Defined default mailbox completion routine and removed code in |
|
the sli layer which checks the mbox_cmpl == 0 to free mail box |
|
resources. |
|
* In lpfc_workq_post_event, clean up comment formatting and remove |
|
unneeded cast of kmalloc's return. |
|
* Removed loop which calls fc_remote_port_unblock and |
|
fc_remote_port_delete for every target as this same effect is |
|
accomplished by the scsi_remove_host call. |
|
* Minor cleanup of header files. Stop header files including |
|
other header files. Removed sentinels which hide multiple |
|
inclusions. Removed unneeded #include directives. |
|
* Fixed memory leaks in mailbox error paths. |
|
* Moved lock from around of lpfc_work_done to lpfc_work_done |
|
itself. |
|
* Removed typedef for LPFC_WORK_EVT_t and left just struct |
|
lpfc_work_evt to comply with linux_scsi review coding style. |
|
* Fixed some trailing whitespaces, spaces used for indentation and |
|
ill-formatting multiline comments. |
|
* Bug fix for Raw IO errors. Reuse of IOCBs now mandates setting |
|
of ulpPU and fcpi_parm to avoid incorrect read check of Write IO |
|
and incorrect read length. |
|
|
|
Changes from 20050110 to 20050124 |
|
|
|
* Changed version number to 8.0.21 |
|
* Removed unpleasant casting in the definition and use of |
|
lpfc_disc_action function pointer array. |
|
* Makefile cleanup. Use ?= operator for setting default |
|
KERNELVERSION and BASEINCLUDE values. Use $(PWD) consistently. |
|
* Removed call to lpfc_sli_intr from lpfc_config_port_post. All |
|
Linux systems will service hardware interrupts while bringing up |
|
the driver. |
|
* Christoph Hellwig change request: Reorg of contents of |
|
lpfc_hbadisc.c, lpfc_scsi.h, lpfc_init.c, lpfc_sli.c, |
|
lpfc_attr.c, lpfc_scsi.c. |
|
* Renamed discovery thread to lpfc_worker thread. Moved handling |
|
of error attention and link attention and mbox event handler to |
|
lpfc_worker thread. |
|
* Removed .proc_info and .proc_name from the driver template and |
|
associated code. |
|
* Removed check of FC_UNLOADING flag in lpfc_queuecommand to |
|
determine what result to return. |
|
* Move modification of FC_UNLOADING flag under host_lock. |
|
* Fix IOERR_RCV_BUFFER_WAITING handling for CT and ELS subsystem. |
|
* Workaround firmware bug for IOERR_RCV_BUFFER_WAITING on ELS |
|
ring. |
|
* Fixed a couple lpfc_post_buffer problems in lpfc_init.c. |
|
* Add missing spaces to the parameter descriptions for |
|
lpfc_cr_delay, lpfc_cr_count and lpfc_discovery_threads. |
|
* Lock before calling lpfc_sli_hba_down(). |
|
* Fix leak of "host" in the error path in the remove_one() path. |
|
* Fix comment for lpfc_cr_count. It defaults to 1. |
|
* Fix issue where we are calling lpfc_disc_done() recursively from |
|
lpfc_linkdown(), but list_for_each_entry_safe() is not safe for |
|
such use. |
|
* Bump lpfc_discovery_threads (count of outstading ELS commands in |
|
discovery) to 32 |
|
* If the SCSI midlayer tries to recover from an error on a lun |
|
while the corresponding target is in the NPR state, lpfc driver |
|
will reject all the resets. This will cause the target to be |
|
moved to offline state and block all the I/Os. The fix for this |
|
is to delay the lun reset to a target which is not in MAPPED |
|
state until the target is rediscovered or nodev timeout is |
|
fired. |
|
|
|
Changes from 20041229 to 20050110 |
|
|
|
* Changed version number to 8.0.20 |
|
* rport fix: use new fc_remote_port_rolechg() function instead of |
|
direct structure change |
|
* rport fix: last null pointer check |
|
* Phase II of GFP_ATOMIC effort. Replaced iocb_mem_pool and |
|
scsibuf_mem_pool with kmalloc and linked list. Inserted list |
|
operations for mempool_alloc calls. General code cleanup. All |
|
abort and reset routines converted. Handle_ring_event |
|
converted. |
|
* If the mbox_cmpl == lpfc_sli_wake_mbox_wait in |
|
lpfc_sli_handle_mb_event, pmb->context1 points to a waitq. Do |
|
not free the structure. |
|
* rport fixes: fix for rmmod crash |
|
* rport fixes: when receiving PRLI's, set node/rport role values |
|
* rport fixes: fix for unload and for fabric port deletes |
|
* VPD info bug fix. |
|
* lpfc_linkdown() should be able to process all outstanding events |
|
by calling lpfc_disc_done() even if it is called from |
|
lpfc_disc_done() Moving all events from phba->dpc_disc to local |
|
local_dpc_disc prevents those events from being processed. |
|
Removing that queue. From now on we should not see "Illegal |
|
State Transition" messages. |
|
* Release host lock and enable interrupts when calling |
|
del_timer_sync() |
|
* All related to rports: Clean up issues with rport deletion |
|
Convert to using block/unblock on list remove (was del/add) |
|
Moved rport delete to freenode - so rport tracks node. |
|
* rport fixes: for fport, get maxframe and class support |
|
information |
|
* Added use of wait_event to work with kthread interface. |
|
* Ensure that scsi_transport_fc.h is always pulled in by |
|
lpfc_scsiport.c |
|
* In remote port changes: no longer nulling target->pnode when |
|
removing from mapped list. Pnode get nulled when the node is |
|
freed (after nodev tmo). This bug was causing i/o received in |
|
the small window while the device was blocked to be errored w/ |
|
did_no_connect. With the fix, it returns host_busy |
|
(per the pre-remote port changes). |
|
* Merge in support for fc transport remote port use. This removes |
|
any consistent bindings within the driver. All scanning is now |
|
on a per-target basis driven by the discovery engine. |
|
|
|
Changes from 20041220 to 20041229 |
|
|
|
* Changed version number to 8.0.19 |
|
* Fixed bug for handling RSCN type 3. Terminate RSCN mode |
|
properly after ADISC handling completes. |
|
* Add list_remove_head macro. Macro cleans up memory allocation |
|
list handling. Also clean up lpfc_reset_bus_handler - routine |
|
does not need to allocate its own scsi_cmnd and scsi_device |
|
structures. |
|
* Fixed potential discovery bug, nlp list corrutpion fix potential |
|
memory leak |
|
* Part 1 of the memory allocation rework request by linux-scsi. |
|
This effort fixes the number of bdes per scsi_buf to 64, makes |
|
the scatter-gather count a module parameter, builds a linked |
|
list of scsi_bufs, and removes all dependencies on lpfc_mem.h. |
|
* Reverted lpfc_do_dpc, probe_one, remove_one to original |
|
implementation. Too many problems (driver not completing |
|
initial discovery, and IO not starting to disks). Backs out |
|
kthread patch. |
|
* Fix race condition in lpfc_do_dpc. If wake_up interrupt occurs |
|
while lpfc_do_dpc is running disc_done and the dpc list is |
|
empty, the latest insertion is missed and the schedule_timeout |
|
does not wakeup. The sleep interval is MAX_SCHEDULE_TIMEOUT |
|
defined as ~0UL >> 1, a very large number. Hacked it to 5*HZ |
|
for now. |
|
* Fixed bug introduced when discovery thread implementation was |
|
moved to kthread. kthread_stop() is not able to wake up thread |
|
waiting on a semaphore and "modprobe -r lpfc" is not always |
|
(most of the times) able to complete. Fix is in not using |
|
semaphore for the interruptable sleep. |
|
* Small Makefile cleanup - Remove remnants of 2.4 vs. 2.6 |
|
determination. |
|
|
|
Changes from 20041213 to 20041220 |
|
|
|
* Changed version number to 8.0.18 |
|
* Janitorial cleanup after removal of sliinit and ringinit[] ring |
|
statistic is owned by the ring and SLI stats are in sli |
|
structure. |
|
* Integrated patch from Christoph Hellwig <[email protected]> Kill |
|
compile warnings on 64 bit platforms: %variables for %llx format |
|
specifiers must be caste to long long because %(u)int64_t can |
|
just be long on 64bit platforms. |
|
* Integrated patch from Christoph Hellwig <[email protected]> Removes |
|
dead code. |
|
* Integrated patch from Christoph Hellwig <[email protected]>: use |
|
kthread interface. |
|
* Print LPFC_MODULE_DESC banner in module init routine. |
|
* Removed sliinit structure and ringinit[] array. |
|
* Changed log message number from 324 to 326 in lpfc_sli.c. |
|
* Wait longer for commands to complete in lpfc_reset_bus_handler |
|
and lpfc_reset_bus_handler. Also use schedule_timeout() instead |
|
of msleep() and add error message in lpfc_abort_handler() |
|
* When setting lpfc_nodev_tmo, from dev_loss set routine, make 1 |
|
sec minimum value. |
|
* Functions which assume lock being held were called without lock |
|
and kernel complained about unlocking lock which is not locked. |
|
* Added code in linkdown to unreg if we know login session will be |
|
terminated. |
|
* Removed automap config parameter and fixed up use_adisc logic to |
|
include FCP2 devices. |
|
|
|
Changes from 20041207 to 20041213 |
|
|
|
* Changed version number to 8.0.17 |
|
* Fix sparse warnings by adding __iomem markers to lpfc_compat.h. |
|
* Fix some sparse warnings -- 0 used as NULL pointer. |
|
* Make sure there's a space between every if and it's (. |
|
* Fix some overly long lines and make sure hard tabs are used for |
|
indentation. |
|
* Remove all trailing whitespace. |
|
* Integrate Christoph Hellwig's patch for 8.0.14: if |
|
pci_module_init fails we need to release the transport template. |
|
(also don't print the driver name at startup, linux drivers can |
|
be loaded without hardware present, and noise in the log for |
|
that case is considered unpolite, better print messages only for |
|
hardware actually found). |
|
* Integrate Christoph Hellwig's patch for 8.0.14: Add missing |
|
__iomem annotations, remove broken casts, mark functions static. |
|
Only major changes is chaning of some offsets from word-based to |
|
byte-based so we cans simply do void pointer arithmetics (gcc |
|
extension) instead of casting to uint32_t. |
|
* Integrate Christoph Hellwig's patch for 8.0.14: flag is always |
|
LPFC_SLI_ABORT_IMED, aka 0 - remove dead code. |
|
* Modified preprocessor #ifdef, #if, #ifndef to reflect upstream |
|
kernel submission. Clean build with make clean;make and make |
|
clean;make ADVANCED=1 on SMP x86, 2.6.10-rc2 on RHEL 4 Beta |
|
1. IO with a few lips and a long cable pull behaved accordingly. |
|
* Implement full VPD support. |
|
* Abort handler will try to wait for abort completion before |
|
returning. Fixes some panics in iocb completion code path. |
|
|
|
Changes from 20041130 to 20041207 |
|
|
|
* Changed version number to 8.0.16 |
|
* Hung dt session fix. When the midlayer calls to abort a scsi |
|
command, make sure the driver does not complete post-abort |
|
handler. Just NULL the iocb_cmpl callback handler and let SLI |
|
take over. |
|
* Add Read check that uses SLI option to validate all READ data |
|
actually received. |
|
|
|
|
|
Changes from 20041123 to 20041130 |
|
|
|
* Changed version number to 8.0.15 |
|
* Ifdef'd unused "binary" attributes by DFC_DEBUG for clean |
|
compiles |
|
* Stop DID_ERROR from showing up along with QUEUE_FULL set by the |
|
Clarion array (SCSI error ret. val. 0x70028) There is no need |
|
for driver to hard fail command which was failed by the target |
|
device. |
|
* Fix for Scsi device scan bug reported on SourceForge. Driver |
|
was returning a DID_ERROR in lpfc_handle_fcp_error causing |
|
midlayer to mark report luns as failing even though it |
|
succeeded. |
|
* Don't ignore SCSI status on underrun conditions for inquiries, |
|
test unit ready's, etc. This was causing us to lose |
|
reservation conflicts, etc |
|
|
|
Changes from 20041018 to 20041123 |
|
|
|
* Changed version number to 8.0.14 |
|
* Added new function "iterator" lpfc_sli_next_iocb_slot() which |
|
returns pointer to iocb entry at cmdidx if queue is not full. |
|
It also updates next_cmdidx, and local_getidx (but not cmdidx) |
|
* lpfc_sli_submit_iocb() copies next_cmdidx into cmdidx. Now it is |
|
the only place were we are updating cmdidx. |
|
* lpfc_sli_update_ring() is split in to two -- |
|
lpfc_sli_update_ring() and lpfc_sli_update_full_ring(). |
|
* lpfc_sli_update_ring() don't to read back correct value of |
|
cmdidx. |
|
* Simplified lpfc_sli_resume_iocb() and its use. |
|
* New static function lpfc_sli_next_iocb(phba, pring, &piocb) to |
|
iterate through commands in the TX queue and new command (at the |
|
end). |
|
* Reduced max_lun to 256 (due to issues reported to some arrays). |
|
Fixed comment, and macro values so def=256, min=1, max=32768. |
|
* Fix an obvious typo/bug: kfree was used to free lpfc_scsi_buf |
|
instead of mempool_free in lpfc_scsiport.c. |
|
* Suppress nodev_tmo message for FABRIC nodes. |
|
* Fixed some usage of plain integer as NULL pointer. |
|
* Bug fix for FLOGI cmpl, lpfc_els_chk_latt error path code |
|
cleanup. |
|
* Fixup lpfc_els_chk_latt() to have Fabric NPorts go thru |
|
discovery state machine as well. |
|
* Fixes to lpfc_els_chk_latt(). |
|
* Use DID not SCSI target id as a port_id and add some missing |
|
locks in lpfc_fcp.c. |
|
* Changed eh_abort_handler to return FAILED if command is not |
|
found in driver. |
|
* Fix crash: paging request at virtual address 0000000000100108 - |
|
a result of removing from the txcmpl list item which was already |
|
removed (100100 is a LIST_POISON1 value from the next pointer |
|
and 8 is an offset of the "prev") Driver runs out of iotags and |
|
does not handle that case well. The root of the proble is in the |
|
initialization code in lpfc_sli.c |
|
* Changes to work with proposed linux kernel patch to support |
|
hotplug. |
|
* Zero out seg_cnt in prep_io failure path to prevent double sg |
|
unmap calls. |
|
* Fix setting of upper 32 bits for Host Group Ring Pointers if in |
|
SLIM. Old code was inappropriately masking off low order bits. |
|
* Use scsi_[activate|deactivate]_tcq calls provided in scsi_tcq.h. |
|
* Integrated patch from Christoph Hellwig ([email protected]): don't call |
|
pci_dma_sync_* on coherent memory. pci_dma_sync_* is need and |
|
must be used only with streaming dma mappings pci_map_*, not |
|
coherent mappings. Note: There are more consistent mappings |
|
that are using pci_dma_sync calls. Probably these should be |
|
removed as well. |
|
* Modified lpfc_free_scsi_buf to accommodate all three scsi_buf |
|
free types to alleviate miscellaneous panics with cable pull |
|
testing. |
|
* Set hotplug to default 0 and lpfc_target_remove to not remove |
|
devices unless hotplug is enabled. |
|
* Fixed discovery bug: plogi cmpl uses ndlp after its freed. |
|
* Fixed discovery bug: rnid acc cmpl, can potentially use ndlp |
|
after its freed. |
|
* Modularize code path in lpfc_target_remove(). |
|
* Changes to support SCSI hotplug (ifdef'ed out because they need |
|
kernel support USE_SCAN_TARGET requires kernel support to export |
|
the interface to scsi_scan_target and to move the SCAN_WILD_CARD |
|
define to a general scsi header file. USE_RESCAN_HOST requires |
|
kernel support to export an interface to scan_scsi_host() with |
|
the rescan flag turned on). |
|
* Removed redundant variable declaration of lpfc_linkdown_tmo. |
|
* Fix for large port count remove test. |
|
* Added check to see if BAR1 register is valid before using BAR1 |
|
register for programming config_port mail box command. |
|
* Added lpfc_scsi_hotplug to enable/disable driver support of SCSI |
|
hotplug. |
|
* Changed lpfc_disc_neverdev() to lpfc_disc_illegal() and changed |
|
lpfc_disc_nodev() to lpfc_disc_noop(). Adjusted appropriate |
|
events to use these routines. |
|
* Add support for SCSI device hotplug. |
|
* Take dummy lpfc_target's into account for lpfc_slave_destroy(). |
|
* Bug fix to store WWPN / WWNN in NameServer / FDMI lpfc_nodelist |
|
entries. |
|
* Added slavecnt in lpfc_target for diagnostic purposes. |
|
* Added lpfc_hba load/unload flags to take care of special cases |
|
for add/remove device. |
|
* Have target add/remove delay before scanning. |
|
* Have rmmod path cleanup blocked devices before scsi_remove_host. |
|
* Added a #define for msleep for 2.6.5 kernels. |
|
* In reset bus handler if memory allocation fails, return FAILED |
|
and not SUCCESS. |
|
* Have lpfc eh handlers, bus_reset and lun_reset, wait for all |
|
associated I/Os to complete before returning. |
|
* Fix memset byte count in lpfc_hba_init so that |
|
LP1050 would initialize correctly. |
|
* Backround nodev_timeout processing to DPC This enables us to |
|
unblock (stop dev_loss_tmo) when appopriate. |
|
* Fix array discovery with multiple luns. The max_luns was 0 at |
|
the time the host structure was initialized. lpfc_cfg_params |
|
then set the max_luns to the correct value afterwards. |
|
* Remove unused define LPFC_MAX_LUN and set the default value of |
|
lpfc_max_lun parameter to 512. |
|
* Reduced stack usage of lpfc_hba_init. |
|
* Cleaned up the following warning generated by |
|
scripts/checkincludes.pl lpfc_fcp.c: scsi/scsi_cmnd.h is |
|
included more than once. |
|
* Replaced "set_current_state(TASK_UNINTERRUPTIBLE); |
|
schedule_timeout(timeout)" with "msleep(timeout)". |
|
* Fixnode was losing starget when rediscovered. We saw messages |
|
like: lpfc 0000:04:02.0: 0:0263 Cannot block scsi target as a |
|
result. Moved starget field into struct lpfc_target which is |
|
referenced from the node. |
|
* Add additional SLI layer logging in lpfc_sli.c. |
|
* Ignore more unexpected completions in lpfc_nportdisc.c. |
|
* Can not call lpfc_target_unblock from the soft interrupt |
|
context. It seems to be not nessasery to unblock target from |
|
nodev timeout. |
|
* Introduce and use less lethal event handler for unexpected |
|
events in lpfc_nportdisc.c. |
|
* Can not call fc_target_(un)block() functions with interrupts |
|
disabled in lpfc_scsiport.c. |
|
* Added new configuration parameter, lpfc_max_luns range 1-32768, |
|
default 32768. |
|
* Allow lpfc_fcp.c to call lpfc_get_hba_sym_node_name(). |
|
* Increase nodev timeout from 20 seconds to 30 seconds. |
|
* Replace some kfree((void*)ptr) with kfree(ptr). |
|
* Make 3 functions static: lpfc_get_hba_sym_node_name, |
|
lpfc_intr_prep and lpfc_setup_slim_access. Move lpfc_intr_prep |
|
and lpfc_setup_slim_access so they're defined before being used. |
|
* Remove an unnecessary list_del() in lpfc_hbadisc.c. |
|
* Set nlp_state before calling lpfc_nlp_list() since this will |
|
potentially call fc_target_unblock which may cause a race in |
|
queuecommand by releasing host_lock. |
|
* Since lpfc_nodev_tmo < dev_loss_tmo remove queuecommand |
|
DID_BAD_TARGET return for now. |
|
* Fix a problem with rcv logo. |
|
* Remove unused portstatistics_t structure. |
|
* Remove #if 0 and unnecessary checks in lpfc_fcp.c. |
|
* Simplify lpfc_issue_lip: Extra layer of protection removed. |
|
* Grab lock before calling lpfc_sli_issue_mbox(phba, pmb, |
|
MBX_NOWAIT) in lpfc_sli_issue_mbox_wait(). |
|
|
|
Changes from 20040920 to 20041018 |
|
|
|
* Changed version number to 8.0.13 |
|
* Hide some attributes using #ifndef DFC_DEBUG ... #endif. |
|
* Modify Makefile to (1) make BUILD_NO_DEBUG=1 will hide some |
|
(binary) attributes (2) make BUILD_FC_TRANS=0 will build driver |
|
for 2.6.5 kernel with block/unblock patch. |
|
* Modified #ifdef names. |
|
* Added support for proposed FC transport host attributes (which |
|
replaces some of the attributes we had local to the driver). |
|
Removed the binary statistics sysfs attribute. |
|
* Added extra ELS verbose logging for ELS responses. |
|
* Added recognition for BUILD_FC_TRANS=2 to Makefile to define |
|
FC_TRANS_VER2. |
|
* Add a pointer for link stats allocation. |
|
* Exported lpfc_get_hba_sym_node_name for use by FC_TRANS_VER2 |
|
sysfs routines. |
|
* Fix discovery problem in lip testing: if device sends an ELS cmd |
|
(i.e. LOGO) before our FLOGI completes it should be LS_RJT'ed. |
|
* Moved #defines around to provide target_add/remove for upstream |
|
kernel deliverables only not SLES9. Provided ifdefs to #include |
|
target_block/unblock only if FC_TRANS_VER1. |
|
* Add sanity check in lpfc_nlp_list move setting nlp_Target |
|
outside #ifdef. |
|
* Added a blocked member to the lpfc_target structure for |
|
block/unblock. This member allows the driver to know when to |
|
unblock for pci_remove_one or pci_add_one. #ifdef'd some more |
|
block/unblock stuff and removed some defensive checks from |
|
target_block/unblock. |
|
* Moved + 5 second window to dev_loss_tmo setting and updated |
|
comments. |
|
* Removed NULL target check from target_block/unblock and fixed up |
|
a few comments. |
|
* Enable sysfs attributes on 2.6.5 kernels and remove extra |
|
compatibility code. |
|
* Remove any and all trailing whitespace. |
|
* Added message 0718 and return error when dma_map_single fails. |
|
* Changed the fcpCntl2 commands to include an FCP_ prefix to get |
|
rid of build warnings on later 2.6.9-rc kernels. Build |
|
conflicts with scsi/scsi.h. Remove inclusions of scsi/scsi.h |
|
from hbadisc.c, sli.c, and fcp.c since these modules had no |
|
dependencies on scsi.h. |
|
* Fixed a bug with RSCN handling. A RSCN received on one device, |
|
shouldn't affect other devices not referenced by the RSCN. |
|
* Moved #if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,6) to include |
|
lpfc_jedec_to_ascii to prevent warning in SLES 9. |
|
* Update Makefile to account for SLES 9 and scsi-target upstream |
|
kernel. |
|
* This checkin provides block/unblock hooks for the upstream scsi |
|
target kernel and 2.6.5 on SLES9 SP1 with the block/unblock |
|
patch. |
|
* Discovery changes regarding setting targetp->pnode and |
|
ndlp->nlp_Target Ensure fc_target_* routines are called properly |
|
from discovery. Remove list_del's from lpfc_cleanup(). Ensure |
|
all the lpfc_consistent_bind_* routines don't set any driver |
|
structure objects. |
|
* Fix for timeout of READ_LA or READ_SPARAM mailbox command |
|
causing panic. |
|
* Cleanup list_del()'s for Discovery ndlp lists. |
|
* Bug fixes for some insmod/rmmod crashes, link down crashes and |
|
device loss crashes. |
|
* Removed NLP_SEARCH_DEQUE. |
|
* Call lpfc_target_unblock only if the targetp is nonNull and with |
|
the host_lock held. |
|
* Added qcmdcnt back along with misc bug fixes to discovery. |
|
* Changed tgt_io to outfcpio lpfc_fcp.c. |
|
* Fixed errors caused by LIP and cable pulls both with and without |
|
block/unblock patch. |
|
* For now we have to call fc_target_unblock and fc_target_block |
|
with interrupts enabled. |
|
* Save seg_cnt from dma_map_sg. Save scatter-gather start address |
|
and pass back to dma_unmap_sg in error with seg_cnt. |
|
* Incorporating block/unblock calls into driver with ifdefs. This |
|
change is supported by scsi-target-2.6 kernel and forward only. |
|
* Merged in some discovery bug fixes and added tgt io counters. |
|
* Added sysfs attributes/interfaces: read only attribute |
|
"management_version" and write only attribute "issue_lip". |
|
* Fix build on big endian machines: while #if was OK with |
|
__BIG_ENDIAN which defined as 4321, __BIG_ENDIAN_BITFIELD has to |
|
be tested with #ifdef because it does not have any value, it is |
|
either defined or not. |
|
* Add fabric_name and port_type attributes. |
|
* Change mdelay to msleep. mdelay works, but wastefully uses cpu |
|
resources without a lock held. Revert to msleep. Tested with |
|
sg_reset for bus and three attached targets. |
|
* Added the customary #ifndef...#define...#endif to |
|
lpfc_version.h. |
|
* Integrate patches from Christoph Hellwig: two new helpers common |
|
to lpfc_sli_resume_iocb and lpfc_sli_issue_iocb - singificant |
|
cleanup of those two functions - the unused SLI_IOCB_USE_TXQ is |
|
gone - lpfc_sli_issue_iocb_wait loses its flags argument |
|
totally. |
|
* Fix in lpfc_sli.c: we can not store a 5 bit value in a 4-bit |
|
field. |
|
* Moved some routines out of lpfc_fcp.c into more appropriate |
|
files. |
|
* Whitespace cleanup: remove all trailing whitespace. |
|
* Make lpfc_disc_ndlp_show static to lpfc_fcp.c. |
|
* Remove leftover printk and replace some with |
|
printk(KERN_WARNING) |
|
* Trivial: fix a few long lines and a soft tab. |
|
* Remove warnings generated by Sparse against driver (make |
|
C=1). Mostly these are "using integer as pointer warnings" |
|
i.e. use NULL instead of 0. |
|
* Integrated patch from Christoph Hellwig: Quite a lot of changes |
|
here, the most notable is that the phba->slim2p lpfc_dmabuf goes |
|
away in favour of a typede pointer and a dma_addr_t. Due to the |
|
typed pointer lots of the cast mess can go away, and while at it |
|
I also replaced the messy SLI2_SLIM_t with a simple struct |
|
lpfc2_sli2_slim that only contains the part of the union we care |
|
about while using SLI2_SLIM_SIZE for all size calculations |
|
directly. |
|
* Integrated patch from Christoph Hellwig: This streamlines the |
|
I/O completion path a little more, especially taking care of |
|
fast-pathing the non-error case. Also removes tons of dead |
|
members and defines from lpfc_scsi.h - e.g. lpfc_target is down |
|
to nothing more than the lpfc_nodelist pointer. |
|
* Added binary sysfs file to issue mbox commands |
|
* Replaced #if __BIG_ENDIAN with #if __BIG_ENDIAN_BITFIELD for |
|
compatibility with the user space applications. |
|
* Decrease the amount of data in proc_info. |
|
* Condense nodelist flag members. |
|
* Expand INFO for discovery sysfs shost entries. |
|
* Notify user if information exceeds 4k sysfs limit. |
|
* Removed a bunch of unused #defines. |
|
* Added initial sysfs discovery shost attributes. |
|
* Remove unused #defines lpfc_disc.h. |
|
* Fixed failMask nodelist settings. |
|
* Cleanup some old comments / unused variables. |
|
* Add LP101 to list of recognized adapters. |
|
|
|
Changes from 20040908 to 20040920 |
|
|
|
* Changed version number to 8.0.12 |
|
* Removed used #defines: DEFAULT_PCI_LATENCY_CLOCKS and |
|
PCI_LATENCY_VALUE from lpfc_hw.h. |
|
* Changes to accommodate rnid. |
|
* Fix RSCN handling so RSCN NS queries only effect NPorts found in |
|
RSCN data. |
|
* If we rcv a plogi on a NPort queued up for discovery, clear the |
|
NLP_NPR_2B_DISC bit since rcv plogi logic will force NPort thru |
|
discovery. |
|
* Ensure lpfc_target is also cleaned up in lpfc_cleanup(). |
|
* Preliminary changes for block/unblock kernel API extensions in |
|
progress with linux-scsi list. These are name changes and |
|
prototype changes only. |
|
* Added send_abts flag to lpfc_els_abort. For rcv LOGO when ADISC |
|
sent, the XRI of the LOGO rcv'ed is the same as the ADISC |
|
sent. Thus we cannot ABTS the ADISC before sending the LOGO ACC. |
|
* Weed out some unused fc_flags. Add FC_DISC_TMO. |
|
* board_online sysfs attribute added to support libdfc functions |
|
InitDiagEnv and SetBrdEnv. |
|
* Streamline code in lpfc_els_retry fixup abort case in |
|
lpfc_els_timeout_handler(). |
|
* Flush discovery/ELS events when we bring SLI layer down. |
|
* ctlreg and slimem binary attributes added to support libdfc |
|
read/write mem/ctl functions. |
|
* Integrated Christoph Hellwig's patch: Cleanup |
|
lpfc_sli_ringpostbuf_get. |
|
* Modified lpfc_slave_alloc and lpfc_slave_destroy to allocate and |
|
free a dummy target pointer. This allows queuecommand to skip |
|
the NULL target pointer check and avoid the console spam when |
|
slave_alloc fails. |
|
* Fix cfg_scan_down logic, it was reversed. |
|
* Init list head ctrspbuflist. |
|
* Change name of lpfc_driver_abort to lpfc_els_abort since it is |
|
only valid for ELS ring. |
|
* Remove unused third argument for lpfc_consistent_bind_get(). |
|
* Fix up iotag fields in lpfc_prep_els_iocb(). |
|
* Remove log message on code path triggered by lpfc_els_abort(). |
|
* Set host->unique_id in lpfc_fcp.c. |
|
* Removed deadwood: lpfc_target.pHba not necessary anymore. |
|
* Integrated patch from Christoph Hellwig: remove dead |
|
SLI_IOCB_POLL handling. |
|
* Integrated patch from Christoph Hellwig: Streamline I/O |
|
submission and completion path a little. |
|
* Remove unnecessary lpfc_brd_no. Ensure brd_no assignment is |
|
unique. |
|
* Removed unused MAX_FCP_LUN. |
|
* Use mod_timer instead of add_timer for fdmi in lpfc_ct.c. |
|
* Fixed misc discovery problems. |
|
* Move stopping timers till just before lpfc_mem_free() call. |
|
* Fix up NameServer reglogin error path. |
|
* Cleanup possible outstanding discovery timers on rmmod. |
|
* Fix discovery NPort to NPort pt2pt problem. |
|
* Get rid of ip_tmofunc / scsi_tmofunc. |
|
* Integrated patch from Christoph Hellwig: |
|
lpfc_disc_done/lpfc_do_dpc cleanup - lpfc_disc_done can return |
|
void - move lpfc_do_dpc and lpfc_disc_done to lpfc_hbadisc.c - |
|
remove checking of list emptiness before calling lpfc_disc_done, |
|
it handles the empty list case just fine and the additional |
|
instructions cost less then the bustlocked spinlock operations. |
|
* Integrated patch from Christoph Hellwig: This adds a new 64bit |
|
counter instead, brd_no isn't reused anymore. Also some tiny |
|
whitespace cleanups in surrounding code. |
|
* Reorder functions in lpfc_els.c to remove need for prototypes. |
|
* Removed unused prototypes from lpfc_crtn.h - |
|
lpfc_ip_timeout_handler, lpfc_read_pci and lpfc_revoke. |
|
* Removed some unused prototypes from lpfc_crtn.h - |
|
lpfc_scsi_hba_reset, lpfc_scsi_issue_inqsn, |
|
lpfc_scsi_issue_inqp0, lpfc_scsi_timeout_handler. |
|
* Integrated patch from Christoph Hellwig: remove TRUE/FALSE |
|
usage. |
|
* Integrated patch from Christoph Hellwig: Remove unused function |
|
prototypes lpfc_set_pkt_len and lpfc_get_pkt_data from |
|
lpfc_crtn.h - fixes build warnings. |
|
* Removed unused struct lpfc_dmabufip definition from lpfc_mem.h. |
|
* Removed pre-2.6.5 MODULE_VERSION macro from lpfc_compat.h. |
|
* Fixing missing static and removing dead code. |
|
* Adding nodewwn, portwwn and portfcid shost attributes. |
|
* Initial support for CT via sysfs. request payloads of size less |
|
than PAGE_SIZE and rsp payloads of size PAGE_SIZE are supported. |
|
Driver maintains a list of rsp's and passes back rsp's |
|
corresponding to the pid of the calling process. |
|
* Support for RefreshInformation, GetAdapterAttributes, |
|
GetPortStatistics. |
|
* Make nodev-tmo default to 20 seconds. |
|
* Fix up some DSM error cases, unreg_login rpi where needed. |
|
* Fix up comments for fc_target_block / fc_target_unblock. |
|
* Fix up code for scsi_block_requests / scsi_unblock_requests. |
|
* Add NLP_FCP_TARGET for nodeinfo support. |
|
* Move suspend/resume in lpfc_nlp_list under appropriate case - |
|
Used host_lock for DPC to avoid race (remove dpc_lock) |
|
* Fix some corner cases for PLOGI receive - simplify error case |
|
for cmpl_reglogin_reglogin_issue. |
|
* Bug fix for ppc64 EEH MMIO panic - always do readl after |
|
writel's of HBA registers to force flush. |
|
* Get rid of initial static routine declarations in lpfc_hbadisc.c |
|
and lpfc_els.c. |
|
* Updates to discovery processing. |
|
|
|
Changes from 20040823 to 20040908 |
|
|
|
* Changed version number to 8.0.11 |
|
* Removed persistent binding code. |
|
* Display both ASC and ASCQ info. |
|
* Fixed link down->up transitions when linkdown tmo expires. Fix |
|
was in the defensive error checking at the start of |
|
queuecommand. |
|
* Removed lpfc_scsi_timeout_handler as this timer is no longer |
|
required. The midlayer will exhaust retries and then call |
|
lpfc_abort_handler, lpfc_reset_lun_handler, and |
|
lpfc_reset_target_handler. |
|
* Minimal support for SCSI flat space addressing/volume set |
|
addressing. Use 16 bits of LUN address so that flat |
|
addressing/VSA will work. |
|
* Changed 2 occurrences of if( 1 != f(x)) to if(f(x) != 1) |
|
* Drop include of lpfc_cfgparm.h. |
|
* Reduce stack usage of lpfc_fdmi_cmd in lpfc_ct.c. |
|
* Add minimum range checking property to /sys write/store |
|
functions. |
|
* Fix display of node_name and port_name via fc transport |
|
attr. |
|
* Removed biosparam code. |
|
* Removed range checking. phba->config[] array elements are now |
|
embedded into the hba struct. lpfc_config_setup() has been |
|
removed. |
|
* Collapsed lpfc_scsi_cmd_start into lpfc_queuecommand and cleaned |
|
up combined routines. |
|
* Removed unused prototypes myprint and |
|
lpfc_sched_service_high_priority_queue. |
|
* Removed unused function lpfc_nodev. |
|
* Removed scsi_cmnd->timeout_per_command cancelation. SCSI midlayer |
|
now times out all commands - FW is instructed to not timeout. |
|
* Removed polling code from lpfc_scsi_cmd_start. Reorganized |
|
queuecommand and cmd_start some. |
|
|
|
Changes from 20040810 to 20040823 |
|
|
|
* Changed version number to 8.0.10 |
|
* Additional timer changes as per Arjan / Christoph's comments. |
|
* Used mod_timer() instead of del_timer_sync() where appropriate. |
|
* Fixed a use after free case (panic on 2.6.8.1 with |
|
CONFIG_DEBUG_SLAB set). |
|
* Fix compile warning in lpfc_fcp.c. |
|
* Minor fix for log message, that prints unassigned brdno which is |
|
zero. |
|
* Move scsi_host_alloc() to the beginning of probe_one(). This |
|
ensures that host_lock is available at later stages and also |
|
avoids tons of unnecessary initializing if host_alloc() |
|
fails. |
|
* Removed else clause from lpfc_slave_configure that set |
|
sdev->queue_depth. The driver informs the midlayer of its |
|
setting in the template and only overrides if queue tagging is |
|
enabled. |
|
* Added PCI_DEVICE_ID_ZEPHYR and PCI_DEVICE_ID_ZFLY (Junior |
|
Zephyr) support |
|
|
|
Changes from 20040730 to 20040810 |

|
shipped with the 2.6.5 kernel. |
|
* Applied patch from Christoph Hellwig ([email protected]) as follows |
|
"[PATCH] use scsi host private data in ->proc_info. |
|
* Applied patch from Christoph Hellwig ([email protected]) as follows |
|
"Re: [Emulex] Ready for next round. This patch cleans up the memory |
|
allocation routines a little and fixes a missing mempool_destroy and |
|
some missing error handling." |
|
* Changed pointers assignments from 0 to NULL. |
|
* Added fixes to the lpfc_reset_lun_handler and lpfc_reset_bus_handler |
|
entry points that caused kernel to Oops or hang. |
|
* Added fixes to targetless hosts that caused modprobe and insmod to hang. |
|
* Ongoing cleanup to many files |
|

|
create_flag). |
|
* Make lpfc_sli_reset_on_init = 1 |
|
* Minor cleanup to quieten sparse. |
|
* Removed missing function = 0 in tmo routine in lpfc_els.c. |
|
* Moved additional binding parameters into lpfc_defaults.c: |
|
lpfc_automap / lpfc_fcp_bind_method |
|
* Use msecs_to_jiffies() where applicable. |
|
* Only use queue depth attribute only after SLI HBA setup was |
|
completed. |
|
* Put in memory barriers for PPC |
|
* Added PCI_DEVICE_ID_HELIOS and PCI_DEVICE_ID_JFLY (Junior |
|
Helios) support |
|
* Added 4&10 gigabit choices in user option link_speed |
|
* Updated timer logic: Set timer data after init_timer use |
|
timer_pending() instead of expires. |
|
* Removed some remnants of IP over FC support from Kconfig and |
|
Makefile. |
|
* Remove redundant prototypes for lpfc_handle_eratt, |
|
lpfc_handle_latt and lpfc_read_pci. |
|
* Ongoing cleanup of lpfc_init.c. |
|
* Changed LPFC_CFG_DFT_HBA_Q_DEPTH -> LPFC_CFG_HBA_Q_DEPTH. |
|
* Another cleanup stab at lpfc_ct.c. Remove castings, structure |
|
code sanely, remove redundant code, reorganize code so that |
|
functions are invoked after definition. |
|
|
|
Changes from 20040716 to 20040723 |
|
|
|
* Changed version number to 8.0.7 |

* Fixed Persistent binding implementation |
|
* Removed all references to lpfc_scsi_req_tmo |
|
* Removed last references to lun_skip config parameter. |
|
* Removed LPFC_DEV_RPTLUN node failure bit because we don't issue |
|
REPORT_LUNS from the driver anymore. |
|
* Removed LUN-tracking in driver. Removed lpfc_lun struct and |
|
moved any functionality we still need to lpfc_target. |
|
* Added new lpfc_jedec_to_ascii() call and replace two instances |
|
of duplicate code with calls to this function. |
|
* Removed Volume Set Addressing handling on LUN IDs. |
|
* Applied patch from Christoph Hellwig ([email protected]) that |
|
removes dead code belonging to lpfc_build_scsi_cmnd() and its |
|
call path. This is related to the recently removed report_lun |
|
code. |
|
|
|
Changes from 20040709 to 20040716 |
|
|
|
* Changed version number to 8.0.6 |
|
* Removed internal report LUNs usage. Removed functions: |
|
lpfc_disc_issue_rptlun, lpfc_disc_cmpl_rptlun, |
|
lpfc_disc_retry_rptlun and their use. |
|
* Removed usused scheduler prototypes in lpfc_crtn.h |
|
* Replace lpfc_geportname() with generic memcmp(). |
|
* Rearrange code in lpfc_rcv_plogi_plogi_issue() to make it a |

|
separate timers and convert to 1 argument changed |
|
LPFC_NODE_FARP_PEND_t to struct lpfc_node_farp_pend convert |
|
ipfarp_tmo to 1 argument convert target struct tmofunc and |
|
rtplunfunc to 1 argument * cr_count, cr_delay and |
|
discovery_threads are only needed to be module_params and not |
|
visible via sysfs. |
|

|
* Changed LS_RJT to struct ls_rjt. |
|
* Changed CSP to struct csp. |
|
* Changed CLASS_PARMS to struct class_parms. |
|
* Some cosmetic coding style cleanups to lpfc_fcp.c. |
|
* Providing a sysfs interface that dumps the last 32 |
|
LINK_[UP|DOWN] and RSCN events. |
|

|
* Remove qfull timers and qfull logic. |
|
* Convert mbox_tmo, nlp_xri_tmo to 1 argment clock handler |
|
* Removed duplicate extern defs of the bind variables. |
|
* Streamline usage of the defines CLASS2 and CLASS3, removing |
|
un-necessary checks on config[LPFC_CFG_FCP_CLASS]. |
|
* Moving the persistent binding variables to new file |
|
lpfc_defaults.c |
|
* Changed LPFC_SCSI_BUF_t to struct lpfc_scsi_buf. |
|
* Moved config specific code from probe_one() into |
|
config_setup(). Removing a redundant check on scandown value |
|
from bind_setup() as this is already done in config_setup(). |
|
* Changed LPFC_SLI_t to struct lpfc_sli. |
|
* Changed FCP_CMND to struct fcp_cmnd. |
|
* Changed FCP_RSP to struct fcp_rsp. |

|
lpfc_extra_io_tmo, lpfc_nodev_holdio, lpfc_delay_rsp_err, |
|
lpfc_tgt_queue_depth and lpfc_check_cond_err. |
|
* Clock changes consolidating timers, just in the struct lpfc_hba, |
|
to get rid of clkData and pass only one argument to timeout |
|
routine. Also, removing need for outstanding clock linked list |
|
to stop these timers at rmmod. |
|
* Move lpfc.conf contents into lpfc_fcp.c. Removing per adapter |
|
attributes in favor of global attributes. |
|
* Fix a potential null pointer reference of pmbuf in lpfc_ct.c. |
|
* On reset_lun, issue LUN_RESET as opposed to ABORT_TASK_SET. |
|

|
* Introducing two new defines LPFC_ATTR_R and LPFC_ATTR_RW that do |
|
a module_param, MODULE_PARM_DESC, lpfc_param_show, |

[lpfc_param_store] and CLASS_DEVICE_ATTRIBUTE. |
|
* Properly clean up when allocation of a linked BDE fails in the |
|
SCSI queuecommand path. |
|
* Fail SCSI command if dma_map_sg call fails. |
|
* Remove unused macros SWAP_ALWAYS and SWAP_ALWAYS16. |
|
* Reset context2 to 0 on exit in |
|
lpfc_sli_issue_iocb_wait_high_priority() and |
|
lpfc_sli_issue_iocb_wait(). |
|
* Arranging lpfc_scsiport.c to follow style of use after |
|
definition. This removes the need for the cruft of forward |
|
declarations. Also removing a redundant #define ScsiResult as it |
|
already available elsewhere. |
|
* Applying "Streamline lpfc error handling" patch from Christoph |
|
Hellwig ([email protected]) with following modifications: fix |
|
mem leaks, remove some misplaced code that need not be there, |
|
print a message on exit (old code prints two (entry/exit)), make |
|
ret values consistent (either 1/0 or SUCCESS/FAILURE), keep all |
|
eh routines in a single file (lpfc_scsiport.c). |
|
* Move contents of lpfc_module_param.h into lpfc_fcp.c. |
|
* Changed sysfs attributes to CLASS_DEVICE_ATTRIBUTES (previously |
|
DEVICE_ATTRIBUTES). They now appear in |
|
/sys/class/scsi_host/hostx (previously in |
|
/sys/bus/pci/drivers/lpfc/devx). |
|
* Removed lpfc_syfs.h and lpfc_sysfs.c. |
|
* Cleanup of config params. Throttle params have been removed. |
|
max_lun has been removed. max_target is replaced with a #define, |
|
lun_skip is removed. Remove ipfc config params and related |
|
code. |
|
* Changed DMABUF_t usage to struct lpfc_dmabuf. |
|
* Downsizing iCfgParam structure to include a_string, a_low, a_hi |
|
and a_default values only. |
|
* Free SCSI buf safety memory pool on shutdown to eliminate memory |
|
leak. |
|
* Change lpfc_printf_log to a #define. Also include phba->brd_no |
|
and newline in the print string rather than in the #define. |
|
* Remove code that optionally locates Host Group Pointers in host |
|
memory SLIM since this is no longer needed for PPC64, once |
|
CONFIG_PORT uses HBA's view of its BAR0. |
|
* Removed the forward declarations of the sli functions and |
|
rearranging the code in lpfc_sli.c. |
|
* Removed the preamble functionality from logging. |
|
* Make lpfc_sli_hba_setup() return negative error codes on error |
|
and correct the comment left over in lpfc_fcp.c |
|
* Removed the lpfc_loadtime variable. |
|
* Put a space between all ifs and their open parens '('. |
|
* Change Studly_Caps LPFC_SCSI_BUF_t to struct lpfc_scsi_buf. |
|
* Fixed insmod hang after hardware error. |
|
* Relocated scsi_host alloc to before we enable the interrupt |
|
handler |
|
* Add .tmp_versions directory to Makefile clean target. This |
|
directory is created in the 2.6.5+ build process (with Red Hat |
|
kernels at least). |
|
* Changing phba->config to kmalloc lpfc_icfgparam and not |
|
*phba->config. This is manifesting itself as a panic in |
|
pci_release_region(). |
|
* Fix for firmware download / board reset problem. |
|
* Integrated patch from Christoph Hellwig ([email protected]) to |
|
reorganize and cleanup lpfc_fcp.c |
|
* Don't abort commands immediately when there is an RSCN event to |
|
give driver time to rediscover targets before the midlayer |
|
retries the SCSI commands. |
|
|
|
Changes from 20040604 to 20040614 |
|
|
|
* Changed version number to 8.0.4 |
|
* Removed lpfc_valid_lun function. |
|
* Added scsi_buf safety pool to address scsi_buf failures in |
|
queuecommand under low memory conditions. Allocations now come |
|
from kmalloc initially, but if kmalloc fails, the allocation |
|
comes from the safety pool. |
|
* Modified lpfc_slave_alloc to only set the scsi_device->hostdata |
|
pointer if the driver has discovered the target. This routine |
|
always returns success now as well since no error ever occurs in |
|
the alloc routine. |
|
* Mask only info and warning messages. Print all error messages |
|
irrespective of mask. |
|
* Removing lpfc_log_chk_msg_disabled() |
|
* Changed lpfc_printf_log to take struct lpfc_hba * directly |
|
instead of a "board number". |
|
* Convert dma_sync_single to pci_dma_sync_single_for_{device/cpu}. |
|
* Implemented new style log messages. The message strings are now |
|
embedded in the call to lpfc_printf_log. |
|
* Decreased FLOGI discovery timeout to 20 seconds. |
|
* On error in lpfc_pci_probe_one() return -1 and not 1. |
|
* Allow for board numbers that are not sequential, paving the way |
|
for hotplug support. |
|
* scsi_add_host() can fail, so wrap it around in an if(). Also |
|
initiate scsi_scan_host() after attaching the sysfs attributes. |
|
* lpfc_release_version is used only in lpfc_ct.c, so move it there |
|
and mark it as static. |
|
* Removed lpfc_sleep_ms and replaced with mdelay or schedule calls |
|
directly |
|
* Removed all (struct list_head *) casts from clkData-related list |
|
handling in list_add, list_del macros. |
|
* Removed EXPORT_SYMBOLs. |
|
* Removed LPFC_MIN_QFULL and lpfc_qthrottle_up. |
|
* Replace LPFCSCSITARGET_t with struct lpfc_target. |
|
* Replace LPFCSCSILUN_t with struct lpfc_lun. |
|
* Remove unused struct declarations (fcPathId and fcRouteId) from |
|
lpfc_scsi.h. |
|
* Rewrite use of FC transport attributes. |
|
* Fix crash when link is lost. This was due to lpfc_delay_iodone |
|
calling list_del on an object that was never put on a list. |
|
* Remove trailing spaces at the end of all lines. |
|
* Set MAX_FCP_TARGET to 256 from 0xff. Set MAX_FCP_LUN and |
|
MAX_FCP_CMDS to their decimal equivalents and updated |
|
documentation. |
|
|
|
Changes from 20040526 to 20040604 |
|
|
|
* Changed version number to 8.0.3 |
|
* Completed sysfs FC transport support. |
|
* Removed unused fields in SCSI LUN and SCSI Target structures: |
|
void *pTargetProto; void *pTargetOSEnv; void *pLunOSEnv; |
|
* Modified list_for_each to list_for_each_entry. Modified |
|
list_for_each_safe to list_for_each_entry_safe. |
|
* Remove lpfc_dfc.h file. |
|
* Changed pHba->phba, pCommand->pcmd |
|
* Changed plogi_ndlp -> plogindlp, pos_tmp->postmp, pRsp->prsp, |
|
pCmd->pcmd |
|
* Changed pText -> ptext |
|
* Changed p_tmp_buff -> ptmpbuff |
|
* Changed pBufList -> pbuflist, pRsp -> prsp, pCmd -> pcmd |
|
* Changed *pos_tmp -> *postmp, *p_mbuf -> *pmbuf |
|
* Following changes are made to the SCSI fast path: Added |
|
DMA_BUF_t member to the lpfc_scsi_buf_t. This will reduce a |
|
memory allocation in the scsi fast path. Added check for |
|
targetp == NULL in the scsi fast path. Increased number of |
|
scatter gather entries in lpfc_scsi_dma_ext to 4 from 3 and |
|
changed the size of lpfc_scsi_dma_ext to 264 |
|
* Fixing some missing static lpfc_nportdisc.c. |
|
* Reordered #include lines so that lpfc.h doesn't have to #include |
|
other header files. |
|
* Remove lpfc_get_hba_sym_node_name() as a global EXPORT and make |
|
it static. |
|
* Move struct clk_data definition from lpfc_hw.h to lpfc_sli.h. |
|
* Changed LPFC_IOCBQ_t to struct lpfc_iocbq. |
|
* Changed LPFC_SLI_RING_t to struct lpfc_sli_ring. |
|
* Changed LPFC_NODELIST_t to struct lpfc_nodelist. |
|
* Rearranged lpfc_nportdisc.c by moving state machine array |
|
(lpfc_disc_action) and the one function that uses it, |
|
lpfc_disc_state_machine, to the end of the file, removing the |
|
need for the raft of prototypes at the top. |
|
* Changed LPFC_BINDLIST_t to struct lpfc_bindlist. |
|
* Removed lpfc_issue_ct_rsp(), lpfc_sleep(), lpfc_add_bind(), |
|
lpfc_del_bind(), lpfc_sli_wake_mbox_wait() and |
|
lpfc_sli_issue_mbox_wait(). |
|
* Fixed a large number of overly-long lines. |
|
* Fixed some discovery problems: Introduced deferred ndlp removal |
|
when in DSM to avoid panic when in nested DMSs Fix NportId |
|
fffc01 handling to not relogin after LOGO fixed handling of LOGO |
|
on PLOGI issue. |
|
* Changed SLI_CT_REQUEST to lpfc_sli_ct_request. |
|
* Changed NAME_TYPE to struct lpfc_name. |
|
* Changed lpfcCfgParam_t to struct lpfc_cfgparam. |
|
* Changed LPFC_STAT_t to struct lpfc_stats. |
|
* Changed HBAEVT_t to struct lpfc_hba_event. |
|
* Changed Studly_Caps lpfcHBA_t to struct lpfc_hba. |
|
* Removed no longer used tasklet_running flag. |
|
* Removing *PSOME_VAR typedefs and using SOME_VAR* directly. |
|
* Changing .use_clustering to ENABLE_CLUSTERING. |
|
* Modify lpfc_queuecommand to return SCSI_MLQUEUE_HOST_BUSY when |
|
it can't queue a SCSI command. Also, remove cmnds_in_flight |
|
member of struct lpfcHBA for 2.6 kernels as it was only needed |
|
to determine what to return from queuecommand. |
|
* Change return type of lpfc_evt_iocb_free to void as it doesn't |
|
return anything. |
|
* Remove unused cmnd_retry_list and in_retry members in struct |
|
lpfcHBA. |
|
* Remove some instances of unneeded casting of kmalloc's return in |
|
lpfc_scsiport.c |
|
* Remove lpfc_linux_attach() and lpfc_linux_detach(). Integrate |
|
them into lpfc_probe_one() and lpfc_release_one() respectively. |
|
* Remove lpfc_num_iocbs, lpfc_num_bufs module parameters |
|
* Remove #defines for NUM_NODES, NUM_BUFS and NUM_IOCBS |
|
|
|
Changes from 20040515 to 20040526 |
|
|
|
* Changing version number to 8.0.2. |
|
* Including dma-mapping.h as one of the include headers. Also |
|
rearrange the #include order. |
|
* Make functions static as appropriate. |
|
* queuecommand() will now return SCSI_MLQUEUE_HOST_BUSY instead of |
|
1 to backpressure midlayer. |
|
* Removed function prototypes for lpfc_start_timer() and |
|
lpfc_stop_timer() |
|
* Changed timer support to be inline. Clk_data is now declared |
|
right next to the corresponding timer_list entry so we don't |
|
have to allocate these clk_data dynamically. |
|
* Add readls after writels to PCI space to flush the writes. |
|
* Fix misspelled word "safety" in function names. |
|
* Fix up comments in lpfc.conf for per HBA parameters to reflect |
|
new implementation. |
|
* Change lpfc_proc_info handler to get the Nodename from |
|
fc_nodename and not fc_portname. |
|
* Fix up some comments and whitespace in lpfc_fcp.c. |
|
* Formatting changes: get rid of leading spaces in code |
|
* Move discovery processing from tasklet to a kernel thread. |
|
* Move ndlp node from unmap list to map list if ADISC completed |
|
successfully. |
|
* Flush all the ELS IOCBs when there is a link event. |
|
* LP9802 qdepth is twice the LP9802DC qdepth. Delay |
|
elx_sched_init after READ_CONFIG to get max_xri from the |
|
firmware. Reset ELX_CFG_DFT_HBA_Q_DEPTH to max_xri after |
|
READ_CONFIG |
|
* Fix fc_get_cfg_parm() to be more robust and support embedded hex |
|
values. The lpfc_param's are now defined as: |
|
lpfc_log_verbose="lpfc:0,lpfc0:0x10,lpfc1:4,lpfc100:0xffff" The |
|
"," delimter does not matter. It can be anything or not exist at |
|
all. ie param = "lpfc:0lpfc0:0x10.lpfc1:4txtlpfc100:0xffff" will |
|
also work. Additionally the string is treated as case |
|
insensitive. |
|
* Changed all usage of lpfc_find_lun_device() to lpfc_find_lun(). |
|
* Removed unnecessary wrappers lpfc_find_lun_device() and |
|
lpfc_tran_find_lun(). |
|
* Switch from using internal bus/id/lun to similar data from |
|
scsi_device structure. |
|
* Eliminate one-line function lpfc_find_target() |
|
* Added slave_alloc, slave_destory |
|
* lpfc_scsi_cmd_start can now acquire lun pointer from |
|
scsi_device->hostdata, which is setup in slave_alloc. |
|
* Eliminate unnecessary checking on every cmd just to see if we |
|
are accessing the device the first time. |
|
* Remove assumption in lpfc_reset_lun_handler that a valid |
|
lpfc_scsi_buf is hung off of linux's scsi_cmnd->host_scribble |
|
when our reset is called. |
|
|
|
Changes from 20040507 to 20040515 |
|
|
|
* Changed version to 8.0.1 |
|
* Fixed crash on driver rmmod after error injection tests and |
|
lpfc_tasklet deadlock. |
|
* Modified lpfc.conf to remove limit on number of support hosts |
|
* Removed HBAAPI |
|
* Removed duplication of SCSI opcodes from lpfc_fcp.h that are |
|
available in scsi/scsi.h |
|
* Rework module_param usage |

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

|
the divisions setup in lpfc_hw.h. |
|
* Remove phba->iflag reference. |
|
* Several locking improvements. |
|
* Remove functions lpfc_drvr_init_lock, lpfc_drvr_lock, |
|
lpfc_drvr_unlock and lpfc_hipri_*. |
|
* Remove LPFC_DRVR_LOCK and LPFC_DRVR_UNLOCK macros. |
|
* Make lpfc_info() use lpfc_get_hba_model_desc() instead of |
|
rewriting almost identical code. |
|
* Fix 1 overly long line in each of lpfc_cfgparm.h, lpfc_ftp.c and |
|
lpfc_sli.c. |
|
* Fix build for Red Hat 2.6.3 kernel by #defining MODULE_VERSION |
|
only if it isn't already defined. |
|
* Change elx_sli_issue_mbox_wait to return correct error code to |
|
the caller. |
|
* In some of the els completion routines, after calling |
|
lpfc_elx_chk_latt, driver ignores the return code of the |
|
lpfc_elx_chk_latt. This will prevent the discovery state machine |
|
restarting correctly when there are link events in the middle of |
|
discovery state machine running. Fix this by exiting discovery |
|
state machine if lpfc_els_chk_latt returns a non zero value. |
|

|
readable. |
|

* Declared export symbol lpfc_page_alloc and lpfc_page_free |
|
* Changed lpfc version number to 6.98.3 |
|
* Move the definition of MAX_LPFC_BRDS to the only header file |
|
that uses it (lpfc_diag.h). |
|
* Change lpfc_sli_wake_iocb_wait to do a regular wake_up since |
|
lpfc_sli_issue_iocb_wait now sleeps uninterruptible. |
|
* Replace list_for_each() with list_for_each_safe() when a list |
|
element could be deleted. |
|
* Fix IOCB memory leak |
|
|
|
Changes from 20040416 to 20040426 |

|
* Partially removed 32 HBA restriction within driver. Incorported |
|
lpfc_instcnt, lpfc_instance[], and pHba[] into lpfcDRVR |
|
structure Added routines lpfc_get_phba_by_inst() |
|
lpfc_get_inst_by_phba() lpfc_check_valid_phba() |
|
* Turn on attributes "set" & "params" by default. |
|
* Further formatting/whitespace/line length cleanup on: lpfc_ct.c |
|
lpfc_els.c lpfc_fcp.c lpfc_hbadisc.c lpfc_init.c lpfc_ipport.c |
|
lpfc_mbox.c lpfc_nportdisc.c lpfc_sched.c lpfc_sched.h |
|
lpfc_scsi.h lpfc_scsiport.c lpfc_sli.c and lpfc_sli.h |
|

|
modes encountered. |

|
modprobe are killed via ctrl-c |
|
* Remove drivers/scsi from include path |
|
* Wrap use of log message 311 in macro |
|
* Detect failure return from pci_map_sg call in lpfc_os_prep_io |
|
* Fix use-after-free of IOCB in lpfc_sli_process_sol_iocb which |
|
was causing an Oops on 2.6.5 kernel. |
|
* Cleanup use of several gotos not used for error exit. |
|
* Replace memcpy_toio() and memcpy_toio() with endian-dependent |
|
lpfc_memcpy_to_slim() and lpfc_memcpy_from_slim() so that for |
|
big endian hosts like PPC64, the SLIM is accessed 4 bytes at a |
|
time instead of as a byte-stream. |
|
|
|
Changes from 20040409 to 20040416 |
|
|
|
* The scsi_register and scsi_alloc_host OS calls can fail and |
|
return a zero-valued host pointer. A ctrl-C on 2.6 kernels |
|
during driver load will cause this and the driver to panic. |
|
Fixed this bug. Also found a bug in the error_x handling with |
|
lpfc_sli_hba_down - it was in the wrong place and the driver |
|
lock was not held, but needed to be (in lpfc_linux_attach) Fixed |
|
both. Did some minor comment clean up. |
|
* Removed unwanted (void *) castings. |
|
* Replace define of INVALID_PHYS, with kernel 2.6.5's |
|
dma_mapping_error() and add a inline function for earlier |
|
kernels. Remove lpfc_bad_scatterlist(). |
|
* Clean up formatting in hbaapi.h, lpfc.h, lpfc_cfgparm.h, |
|
lpfc_crtn.h, lpfc_ct.c, lpfc_diag.h, lpfc_disc.h, lpfc_els.c, |
|
lpfc_fcp.c, lpfc_hbadisc.c, lpfc_hw.h, lpfc_init.c, |
|
lpfc_ipport.c, lpfc_logmsg.c, lpfc_logmsg.h and lpfc_scsiport.c |
|
- mostly replacing groups of 8 spaces with hard tabs and keeping |
|
lines to 80 column max.. |
|
* Removed LPFC_DRVR_LOCK call from lpfc_unblock_requests for 2.4 |
|
kernels. The lpfc_scsi_done routine already unlocks the driver |
|
lock since it expects this lock to be held. |
|
* Removed global lock capabilities from driver lock routines |
|
* Remove SA_INTERRUPT flag from request_irq |
|
* Move dma_addr_t cast inside of getPaddr macro as everywhere |
|
getPaddr is used, the return is cast to dma_addr_t. |
|
* Clean up formatting in lpfc_sli.c and lpfc_sysfs.c - mostly |
|
replacing groups of 8 spaces with hard tabs and keeping lines |
|
to 80 column max. |
|
* Fix build for RHEL 2.1 BOOT kernels by always #including |
|
interrupt.h in lpfc.h. |
|
* Fix RHEL 3 build by #defining EXPORT_SYMTAB. |
|

|
* Fix build warnings on 2.6 kernels - remove no longer used calls |
|
to character device initialization. |

|
* Removing char interface and ioctl code. |
|
* Change all elx prefixes to lpfc |
|

|
memcpy_fromio(), writel() & readl(). |
|
|
|
Changes from 20040402 to 20040409 |
|
|
|
* Replaced lpfc_read_hbaregs_plus_offset and |
|
lpfc_write_hbaregs_plus_offset functions with readl and writel. |
|
* Get rid of long mdelay's in insmod path |
|
* Changed the way our pci_device_id structures are initialized |
|
* Replace lpfc_read/write_CA/HA/HC/HS with calls to readl() & |
|
writel() directly. |
|
* Increase SLI2_SLIM to 16K Increase cmd / rsp IOCBs accordingly |
|
* Removed lpfc_els_chk_latt from the lpfc_config_post function. |
|
lpfc_els_chk_latt will enable the link event interrupts when |
|
flogi is pending which causes two discovery state machines |
|
running parallelly. |
|
* Add pci_disable_device to unload path. |
|
* Move lpfc_sleep_event from lpfc_fcp.c to lpfc_util_ioctl.c |
|
* Call dma_map_single() & pci_map_single() directly instead of via |
|
macro lpfc_pci_map(). Allow address 0 for PPC64. |
|
* Change sleep to uninterruptible in lpfc_sli_issue_icob_wait |
|
because this function doesn't handle signals. |
|
* Move lpfc_wakeup_event from lpfc_fcp.c to lpfc_ioctl.c |
|
* Remove unneeded #include <linux/netdevice.h> |
|
* Remove unused clock variables lpfc_clkCnt and lpfc_sec_clk. |
|
* Get rid of capitalization of function names. |
|
* Removed lpfc_addr_sprintf. |
|
* Implemented gotos in lpfc_linux_attach for error cases. |
|
* Replace mlist->dma.list = dmp->dma.list; to mlist = dmp. |
|

|
lpfc_get_OsNameVersion to lpfc_get_os_nameversion. |
|

|
* Renamed elx_sched.c to lpfc_sched.c |
|
* Renamed elx_mem.c to lpfc_mem.c |
|

|
lpfc.h |
|
* Remove lpfc_hba.h |
|
* Remove duplicate rc definitions from |
|
* Removed code which used next pointer to store mbox structure. |
|
* Cleaned up list iterations. |
|
* Removed non list manipulation of the next pointers. |
|
* Change list_del()/INIT_LIST_HEAD sequences to list_del_init() |
|
* In ELX_IOCBQ_t: Moved hipri_trigger field to iocb_flag. Combined |
|
hipri_wait_queue and rsp_iocb in union |
|

|
* Clean up formatting of elx_sli.h (tabs for indents, 80 column |
|
lines). |
|
* Remove unused elxclock declaration in elx_sli.h. |
|
* Since everywhere IOCB_ENTRY is used, the return value is cast, |
|
move the cast into the macro. |
|
* Split ioctls out into separate files |
|
|
|
Changes from 20040326 to 20040402 |
|
|
|
* Updated ChangeLog for 20040402 SourceForge drop. |
|
* Use safe list iterator for ndlp list |
|
* Added code to return NLP_STE_FREED_NODE from the discovery |
|
state machine functions if the node is freed from the |
|
function. |
|
* Fixes to DMABUF_t handling |
|
* Fix for load error in discovery |

|
* Implemented the Linux list macros in the discovery code. |
|
Also moved elx_disc.h contents into lpfc_disc.h |
|
* Unused variable cleanup |
|
* Use Linux list macros for DMABUF_t |
|
* Break up ioctls into 3 sections, dfc, util, hbaapi |
|
rearranged code so this could be easily separated into a |
|
differnet module later All 3 are currently turned on by |
|
defines in lpfc_ioctl.c LPFC_DFC_IOCTL, LPFC_UTIL_IOCTL, |
|
LPFC_HBAAPI_IOCTL |
|
* Misc cleanup: some goto's; add comments; clarify function |
|
args |
|
* Added code to use list macro for ELXSCSITARGET_t. |
|
* New list implementation for ELX_MBOXQ_t |
|
* Cleaned up some list_head casting. |
|
* Put IPFC ifdef around two members of struct lpfc_nodelist. |
|
* Cleaned up iocb list using list macros and list_head data |
|
structure. |
|
* lpfc_online() was missing some timer routines that were |
|
started by lpfc_linux_attach(). These routines are now also |
|
started by lpfc_online(). lpfc_offline() only stopped |
|
els_timeout routine. It now stops all timeout routines |
|
associated with that hba. |
|
* Replace separate next and prev pointers in struct |
|
lpfc_bindlist with list_head type. In elxHBA_t, replace |
|
fc_nlpbind_start and _end with fc_nlpbind_list and use |
|
list_head macros to access it. |
|
* Fix ulpStatus for aborting I/Os overlaps with newer firmware |
|
ulpStatus values |
|
* Rework params_show/store to be consistent as the other |
|
routines. Remove generic'ness and rely on set attribute. |
|
* Remove unused log message. |
|
* Collapse elx_crtn.h and prod_crtn.h into lpfc_crtn.h |
|
* Ifdef Scheduler specific routines |
|
* Removed following ununsed ioclt's: ELX_READ_IOCB |
|
ELX_READ_MEMSEG ELX_READ_BINFO ELX_READ_EINVAL ELX_READ_LHBA |
|
ELX_READ_LXHBA ELX_SET ELX_DBG LPFC_TRACE |
|
* Removed variable fc_dbg_flg |
|
* Fixed a bug where HBA_Q_DEPTH was set incorrectly for |
|
3-digit HBAs. Also changed can_queue so midlayer will only |
|
send (HBA_Q_DEPTH - 10) cmds. |
|
* Clean up code in the error path, check condition. Remove |
|
ununsed sense-related fields in lun structure. |
|
* Added code for safety pools for following objects: mbuf/bpl, |
|
mbox, iocb, ndlp, bind |
|
* Wrapped '#include <elx_sched.h>' in '#ifdef USE_SCHEDULER'. |
|
* Fixed 'make clean' target. |
|
* Build now ignores elx_sched.o, and includes lpfc_sysfs.o. |
|
* Wrapped lpfndd.o target in BUILD_IPFC ifdef. |
|
* Removed elx_os.h inclusion in implementation files. |
|
* Removed ELX_OS_IO_t data structure and put data direction |
|
and non scatter/gather physical address into the scsi buffer |
|
structure directly. Moved DRVR_LOCK, putPaddr, getPaddr |
|
macros and some defines into elx.h since they are required |
|
by the whole driver. |
|
* Migrated following ioctls (debug) ELX_DISPLAY_PCI_ALL |
|
ELX_DEVP ELX_READ_BPLIST ELX_RESET_QDEPTH ELX_STAT. |
|
* Step 1 of attempt to move all Debug ioctls to sysfs. |
|
Implemented the following IOCTLs in sysfs: ELX_WRITE_HC |
|
ELX_WRITE_HS ELX_WRITE_HA ELX_WRITE_CA ELX_READ_HC |
|
ELX_READ_HS ELX_READ_HA ELX_READ_CA ELX_READ_MB ELX_RESET |
|
ELX_READ_HBA ELX_INSTANCE ELX_LIP. Also introduced |
|
attribute "set" to be used in conjunction with the above |
|
attributes. |
|
* Removed DLINK, enque and deque declarations now that clock |
|
doesn't use them anymore |
|
* Separated install rule so that BUILD_IPFC has to be set when |
|
make is called in order for the install rule to attempt to |
|
copy the lpfndd.o driver. This change fixes a bug that |
|
occurs because the install rule by default attempted to |
|
install lpfndd.o, whereas the default make rule did not by |
|
default build lpfndd.o. |
|
* Keep track if hbaapi index numbers need to be refreshed. |
|
* Removed prod_os.h from include list. |
|
* Removed LPFC_LOCK and LPFC_UNLOCK macros. Added OS calls |
|
into elx_os_scsiport.c. This file is now empty. |
|
* Added spin_lock_irqsave and spin_unlock_irqrestore calls |
|
into code directly and removed LPFC_LOCK_ and _UNLOCK_ |
|
macros |
|
* Remove references to "elx_clock.h" |
|
* Added utsname.h to include list. The previous checkin to |
|
elx_os.h removed its inclusion of utsname.h since there is |
|
precious little in the file. However, lpfcLINUXfcp.c needs |
|
it and now has it. |
|
* Removed some commented-out code |
|
* Removed elx_lck_t data structure, stray elxDRVR_t type, and |
|
include from file. No longer used. |
|
* Removed two PCI Sync defines. Removed includes - not |
|
needed. Cleaned up macro lines. |
|
* Added two functions from elxLINUXfcp.c. These functions |
|
were IPFC specific. |
|
* Removed hipri lock abstractions and added OS call into code. |
|
Removed elx_lck_t and added spinlock_t directly. Moved two |
|
IPFC functions into lpfc_ipport.c |
|
* Moved IP specific structures to lpfc_ip.h file. |
|
* lpfc_ipfarp_timeout() uses system timer. Remove all usages |
|
of old internal clock support. |
|
* Made changes to compile without IPFC support for the default |
|
build. Added ifdef IPFC for all lpfc_ip.h includes. |
|
* Patched elx_free_scsi_buf |
|
* Removed elx_sched.o from 2.6 dependencies |
|
* Reworked lpfc_pcimap. |
|
* Use Linux swap macros to replace ELX swapping macros |
|
(SWAP_SHORT, SWAP_LONG, SWAP_DATA, SWAP_DATA16, |
|
PCIMEM_SHORT, PCIMEM_LONG, PCIMEM_DATA). |
|
* move in_interrupt() check inside of elx_sleep_ms() |
|
* Moved location of pci.h include. |
|
* Restored elx_lck_t types in elxHBA_t. |
|
* Removed elx_pci_dma_sync call. Also removed some PCI |
|
defines from elx_hw.h and removed the spinlock_t locks that |
|
are no longer used in elx.h |
|
* elx_iodone() now uses system timer. |
|
* elx_qfull_retry() now uses system timer. |
|
* lpfc_put_buf(), lpfc_ip_xri_timeout() and |
|
lpfc_ip_timeout_handler() now use system timer. |
|
* lpfc_fdmi_tmo() and lpfc_qthrottle_up() now use system |
|
timer. |
|
* Removed num_bufs and num_iocbs configuration parameters. |
|
* Fixed a memory corruption bug. This was caused by a memory |
|
write to ndlp structure from lpfc_cmpl_els_acc function. |
|
This ndlp structure was freed from lpfc_els_unsol_event. |
|
* lpfc_disc_timeout() and lpfc_establish_link_tmo() now use |
|
system timer. Also update lpfc_els_retry_delay() to do a |
|
single lock release at the end. |
|
* Remove use of PAN (pseudo adapter number). |
|
* Reintroduced usage of the cross compiler for building on |
|
ppc64 to remove build errors that were cropping up when |
|
using the standard gcc compiler. |
|
* Fix no-unlock-before return in lpfc_els_retry_delay which was |
|
causing a deadlock on insmod in some environments. |
|
* Minor format changes fix up comments |
|
* Create utility clock function elx_start_timer() and |
|
elx_stop_timer(). All timeout routines now use these common |
|
routines. |
|
* Minor formating changes fix up comments |
|
* Minor formatting changes get rid of failover defines for |
|
syntax checking |
|
* Minor formatting changes remove ISCSI defines. |
|

|
* Removed unused elx_scsi_add_timer extern function |
|
declaration. |
|

|
* Comment out lpfndd.o modules_install section as lpfndd.o is |
|
not generated if CONFIG_NET_LPFC is not set. Also refer to |
|
BASEINCLUDE only in out of kernel source module builds as it |
|
will not exist otherwise. |
|
* Removed unused malloc counters from lpfcLINUXfcp.c. |
|
* Remove some unnecessary #includes in lpfcLINUXfcp.c |
|
* Remove unncessary #includes in elxLINUXfcp.c |
|

|
FC_MAX_SEGSZ and FC_MAX_POOL. |
|
* Rewrite of Makefile. Fixes breakages with make -j4 during |
|
kernel compile. Does not recompile all files on every |
|
build. Uses the kernel build's definitions of CFLAGS, |
|
MODFLAGS etc. Removed "make rpm" option. |
|
* Removed unused #defines CLOSED, DEAD, OPENED, NORMAL_OPEN |
|
and unneeded #include of elx_sched.h in elx.h. |
|

|
multiple instances of the parameter switch into a single |
|
instance. |
|
* Use lpfc_is_LC_HBA() macro that tests pcidev->device directly |
|
