|
|
* This source release intended for upstream kernel releases only!

|
|
||
|
|
Changes from 20050323 to 20050413
|
||
|
|
|
||
|
|
* Changed version number to 8.0.28
|
||
|
|
* Fixed build warning for 2.6.12-rc2 kernels: mempool_alloc now
|
||
|
|
requires a function which takes an unsigned int for gfp_flags.
|
||
|
|
* Removed pci dma sync calls to coherent/consistent pci memory.
|
||
|
|
* Merged patch from Christoph Hellwig <hch@lst.de>: split helpers
|
||
|
|
for fabric and nport logins out of lpfc_cmpl_els_flogi.
|
||
|
|
* Removed sysfs attributes that are used to dump the various
|
||
|
|
discovery lists.
|
||
|
|
* Fix for issue where not all luns are seen. Search all lists
|
||
|
|
other than unmap list in lpfc_find_target(). Otherwise INQUIRY
|
||
|
|
to luns on nodes in NPR or other relevant states (PLOGI,
|
||
|
|
PRLI...) are errored back and scan() terminates.
|
||
|
|
* Removed FC_TRANSPORT_PATCHESxxx defines. They're in 2.6.12-rc1.
|
||
|
|
* Compare return value of lpfc_scsi_tgt_reset against SCSI
|
||
|
|
midlayer codes SUCCESS/FAILED which that function returns rather
|
||
|
|
than SLI return code.
|
||
|
|
* Removed extraneous calls to lpfc_sli_next_iotag which should
|
||
|
|
only be called from lpfc_sli_submit_iocb. Also make
|
||
|
|
lpfc_sli_next_iotag static.
|
||
|
|
* Added PCI ID for LP10000-S.
|
||
|
|
* Changes in lpfc_abort_handler(): Return SUCCESS if we did not
|
||
|
|
find command in both TX and TX completion queues. Return ERROR
|
||
|
|
if we timed out waiting for command to complete after abort was
|
||
|
|
issued.
|
||
|
|
* Zero-out response sense length in lpfc_scsi_prep_cmnd to prevent
|
||
|
|
interpretation of stale sense length when the command completes
|
||
|
|
- was causing spurious 0710 messages.
|
||
|
|
* Moved clearing of host_scribble inside host_lock in IO
|
||
|
|
completion path.
|
||
|
|
* Fixed a bunch of mixed tab/space indentation.
|
||
|
|
* Allow hex format numbers in sysfs attribute setting. Fix
|
||
|
|
application hang when invalid numbers are used in sysfs
|
||
|
|
settings.
|
||
|
|
* Removed extra iotag allocation by lpfc_abort_handler.
|
||
|
|
* Clear host_scribble in the scsi_cmnd structure when failing in
|
||
|
|
queuecommand.
|
||
|
|
* Changed logic at top of lpfc_abort_handler so that if the
|
||
|
|
command's host_scibble field is NULL, return SUCCESS because the
|
||
|
|
driver has already returned the command to the midlayer.
|
||
|
|
|
||
|
|
Changes from 20050308 to 20050323
|
||
|
|
|
||
|
|
* Changed version number to 8.0.27
|
||
|
|
* Changed a few lines from patch submitted by Christoph Hellwig
|
||
|
|
(3/19). MAILBOX_WSIZE * (uint32_t) is replaced with an
|
||
|
|
equivalent MAILBOX_CMDSIZE macro.
|
||
|
|
* Merged patch from Christoph Hellwig (3/19): some misc patches
|
||
|
|
against the latest drivers:
|
||
|
|
- stop using volatile. if you need special ordering use memory
|
||
|
|
barriers but that doesn't seem to be the case here
|
||
|
|
- switch lpfc_sli_pcimem_bcopy to take void * arguments.
|
||
|
|
- remove typecast for constants - a U postfix marks them
|
||
|
|
unsigned int in C
|
||
|
|
- add a MAILBOX_CMD_SIZE macro, as most users of
|
||
|
|
MAILBOX_CMD_WSIZE didn't really want the word count
|
||
|
|
- kill struct lpfc_scsi_dma_buf and embedded the two members
|
||
|
|
directly in struct lpfc_scsi_buf
|
||
|
|
- don't call dma_sync function on allocations from
|
||
|
|
pci_pool_alloc - it's only for streaming mappings (pci_map_*)
|
||
|
|
* Merged patch from Christoph Hellwig (3/19) - nlp_failMask isn't
|
||
|
|
ever used by the driver, just reported to userspace (and that in
|
||
|
|
a multi-value file which is against the sysfs guidelines).
|
||
|
|
* Change pci_module_init to pci_register_module() with appropriate
|
||
|
|
ifdefs.
|
||
|
|
* Added #include <linux/dma-mapping.h> as required by the DMA
|
||
|
|
32bit and 64bit defines on some archs.
|
||
|
|
* Merged patch from Christoph Hellwig (03/19) - fix initialization
|
||
|
|
order - scsi_add_host must happen last from scsi POV. Also some
|
||
|
|
minor style/comment fixups.
|
||
|
|
* Fixed use of TRANSPORT_PATCHES_V2 by changing to
|
||
|
|
FC_TRANSPORT_PATCHES_V2.
|
||
|
|
|
||
|
|
Changes from 20050223 to 20050308
|
||
|
|
|
||
|
|
* Changed version number to 8.0.26
|
||
|
|
* Revise TRANSPORT_PATCHES_V2 so that lpfc_target is removed and
|
||
|
|
rport data is used instead. Removed device_queue_hash[].
|
||
|
|
* Changed RW attributes of scan_down, max_luns and fcp_bind_method
|
||
|
|
to R only.
|
||
|
|
* Fixed RSCN handling during initial link initialization.
|
||
|
|
* Fixed issue with receiving PLOGI handling when node is on NPR
|
||
|
|
list and marked for ADISC.
|
||
|
|
* Fixed RSCN timeout issues.
|
||
|
|
* Reduced severity of "SCSI layer issued abort device" message to
|
||
|
|
KERN_WARNING.
|
||
|
|
* Feedback from Christoph Hellwig (on 2/5) - In the LPFC_EVT_SCAN
|
||
|
|
case the caller already has the target ID handly, so pass that
|
||
|
|
one in evt_arg1.
|
||
|
|
* Fix compile warning/resultant panic in
|
||
|
|
lpfc_register_remote_port().
|
||
|
|
|
||
|
|
Changes from 20050215 to 20050223
|
||
|
|
|
||
|
|
* Changed version number to 8.0.25
|
||
|
|
* Add appropriate comments to lpfc_sli.c.
|
||
|
|
* Use DMA_64BIT_MASK and DMA_32BIT_MASK defines instead of
|
||
|
|
0xffffffffffffffffULL & 0xffffffffULL respectively. Use pci
|
||
|
|
equivalents instead of dma_set_mask and also modify condition
|
||
|
|
clause to actually exit on error condition.
|
||
|
|
* Restart els timeout handler only if txcmplq_cnt. On submission,
|
||
|
|
mod_timer the els_tmofunc. This prevents the worker thread from
|
||
|
|
waking up the els_tmo handler un-necessarily. The thread was
|
||
|
|
being woken up even when there were no pending els commands.
|
||
|
|
* Added new typedefs for abort and reset functions.
|
||
|
|
* Collapsed lpfc_sli_abort_iocb_xxx into a single function.
|
||
|
|
* Collapsed lpfc_sli_sum_iocb_xxx into a single function.
|
||
|
|
* Removed TXQ from all abort and reset handlers since it is never
|
||
|
|
used.
|
||
|
|
* Fixed Oops panic in 8.0.23 (reported on SourceForge). The
|
||
|
|
driver was not handling LPFC_IO_POLL cases correctly in
|
||
|
|
fast_ring_event and was setting the tgt_reset timeout to 0 in
|
||
|
|
lpfc_reset_bus_handler. This 0 timeout would not allow the FW
|
||
|
|
to timeout ABTS's on bad targets and allow the driver to have an
|
||
|
|
iocb on two lists. Also split the lpfc_sli_ringtxcmpl_get
|
||
|
|
function into two routines to match the fast and slow completion
|
||
|
|
semantics - ELS completions worked for the wrong reasons. Also
|
||
|
|
provided new log message number - had two 0326 entries.
|
||
|
|
* Removed unused #define LPFC_SCSI_INITIAL_BPL_SIZE.
|
||
|
|
* Removed unused struct lpfc_node_farp_pend definition.
|
||
|
|
* Removed unused #define LPFC_SLIM2_PAGE_AREA.
|
||
|
|
* Changed zeros used as pointers to NULL.
|
||
|
|
* Removed unneeded braces around single line in lpfc_do_work.
|
||
|
|
* Close humongous memory leak in lpfc_sli.c - driver was losing 13
|
||
|
|
iocbq structures per LIP.
|
||
|
|
* Removed last of GFP_ATOMIC allocations.
|
||
|
|
* Locks are not taken outside of nportdisc, hbadisc, els and most
|
||
|
|
of the init, sli, mbox and ct groups of functions
|
||
|
|
* Fix comment for lpfc_sli_iocb_cmd_type to fit within 80 columns.
|
||
|
|
* Replaced wait_event() with wait_event_interruptible().
|
||
|
|
wait_event() puts the woker thread in an UNINTERRUPTIBLE state
|
||
|
|
causing it to figure in load average calculations. Also add a
|
||
|
|
BUG_ON to the ret code of wait_event_interruptible() since the
|
||
|
|
premise is that the worker thread is signal-immune.
|
||
|
|
|
||
|
|
Changes from 20050208 to 20050215
|
||
|
|
|
||
|
|
* Changed version number to 8.0.24
|
||
|
|
* Fixed a memory leak of iocbq structure. For ELS solicited iocbs
|
||
|
|
sli layer now frees the response iocbs after processing it.
|
||
|
|
* Closed large memory leak -- we were losing 13 iocbq structures
|
||
|
|
per LIP.
|
||
|
|
* Changing EIO and ENOMEM to -EIO and -ENOMEM respectively.
|
||
|
|
* Cleanup of lpfc_sli_iocb_cmd_type array and typing of iocb type.
|
||
|
|
* Implemented Christoph Hellwig's feedback from 02/05: Remove
|
||
|
|
macros putLunHigh, putLunLow. Use lpfc_put_lun() inline instead.
|
||
|
|
* Integrated Christoph Hellwig's feedback from 02/05: Instead of
|
||
|
|
cpu_to_be32(), use swab16((uint16_t)lun). This is the same as
|
||
|
|
"swab16() on LE" and "<<16 on BE".
|
||
|
|
* Added updates for revised FC remote port patch (dev_loss_tmo
|
||
|
|
moved to rport, hostdata renamed dd_data, add fc_remote_host()
|
||
|
|
on shutdown).
|
||
|
|
* Removed unnecessary function prototype.
|
||
|
|
* Added code to prevent waking up worker thread after the exit of
|
||
|
|
worker thread. Fixes panic seen with insmod/rmmod testing with
|
||
|
|
70 disks.
|
||
|
|
* Integrated Christoph Hellwig's patch from 1/30: Make some
|
||
|
|
variables/code static (namely lpfcAlpaArray and
|
||
|
|
process_nodev_timeout()).
|
||
|
|
* Integrated Christoph Hellwig's patch from 1/30: Use
|
||
|
|
switch...case instead of if...else if...else if while decoding
|
||
|
|
JDEC id.
|
||
|
|
|
||
|
|
Changes from 20050201 to 20050208
|
||
|
|
|
||
|
|
* Changed version number to 8.0.23
|
||
|
|
* Make lpfc_work_done, lpfc_get_scsi_buf,
|
||
|
|
lpfc_mbx_process_link_up, lpfc_mbx_issue_link_down and
|
||
|
|
lpfc_sli_chipset_init static.
|
||
|
|
* Cleaned up references to list_head->next field in the driver.
|
||
|
|
* Replaced lpfc_discq_post_event with lpfc_workq_post_event.
|
||
|
|
* Implmented Christoph Hellwig's review from 2/5: Check for return
|
||
|
|
values of kmalloc.
|
||
|
|
* Integrated Christoph Hellwig's patch from 1/30: Protecting
|
||
|
|
scan_tmo and friends in !FC_TRANSPORT_PATCHES_V2 &&
|
||
|
|
!USE_SCAN_TARGET.
|
||
|
|
* Integrated Christoph Hellwig's patch from 1/30: Some fixes in
|
||
|
|
the evt handling area.
|
||
|
|
* Integrated Christoph Hellwig's patch from 1/30: Remove usage of
|
||
|
|
intr_inited variable. The interrupt initilization from OS side
|
||
|
|
now happens in lpfc_probe_one().
|
||
|
|
* Integrated Christoph Hellwig's patch from 1/30: remove shim
|
||
|
|
lpfc_alloc_transport_attr - remove shim lpfc_alloc_shost_attrs -
|
||
|
|
remove shim lpfc_scsi_host_init - allocate phba mem in scsi's
|
||
|
|
hostdata readjust code so that they are no use after free's
|
||
|
|
(don't use after scsi_host_put) - make lpfc_alloc_sysfs_attr
|
||
|
|
return errors
|
||
|
|
* Fixed panic in lpfc_probe_one(). Do not delete in a list
|
||
|
|
iterator that is not safe.
|
||
|
|
* Clean up fast lookup array of the fcp_ring when aborting iocbs.
|
||
|
|
* Following timeout handlers moved to the lpfc worker thread:
|
||
|
|
lpfc_disc_timeout, lpfc_els_timeout, lpfc_mbox, lpfc_fdmi_tmo,
|
||
|
|
lpfc_nodev_timeout, lpfc_els_retry_delay.
|
||
|
|
* Removed unused NLP_NS_NODE #define.
|
||
|
|
* Integrated Christoph Hellwig's patch from 1/30: remove unused
|
||
|
|
lpfc_hba_list; remove unused lpfc_rdrev_wd30; remove
|
||
|
|
lpfc_get_brd_no and use Linux provided IDR.
|
||
|
|
* Changed board reset procedure so that lpfc_sli_send_reset()
|
||
|
|
writes the INITFF bit and leaves lpfc_sli_brdreset() to clear
|
||
|
|
the bit.
|
||
|
|
* Removed outfcpio sysfs device attribute.
|
||
|
|
* VPD changes: 1) Modify driver to use the model name and
|
||
|
|
description from the VPD data if it exists 2) Rework use of DUMP
|
||
|
|
mailbox command to support HBAs with 256 bytes of SLIM.
|
||
|
|
* Fixed compile error for implicit definition of struct
|
||
|
|
scsi_target
|
||
|
|
|
||
|
|
Changes from 20050124 to 20050201
|
||
|
|
|
||
|
|
* Changed version number to 8.0.22
|
||
|
|
* Moved discovery timeout handler to worker thread. There are
|
||
|
|
function calls in this function which are not safe to call from
|
||
|
|
HW interrupt context.
|
||
|
|
* Removed free_irq from the error path of HBA initialization.
|
||
|
|
This will fix the free of uninitialised IRQ when config_port
|
||
|
|
fails.
|
||
|
|
* Make sure function which processes unsolicited IOCBs on ELS ring
|
||
|
|
still is called with the lock held.
|
||
|
|
* Clear LA bit from work_ha when we are not supposed to handle LA.
|
||
|
|
* Fix double locking bug in the error handling part of
|
||
|
|
lpfc_mbx_cmpl_read_la.
|
||
|
|
* Implemented fast IOCB processing for FCP ring.
|
||
|
|
* Since mboxes are now unconditionally allocated outside of the
|
||
|
|
lock, free them in cases where they are not used.
|
||
|
|
* Moved out a couple of GFP_ATOMICs in lpfc_disc_timeout, to
|
||
|
|
before locks so that they can GFP_KERNEL instead. Also cleaned
|
||
|
|
up code.
|
||
|
|
* Collapsed interrupt handling code into one function.
|
||
|
|
* Removed event posting and handling of solicited and unsolicited
|
||
|
|
iocbs.
|
||
|
|
* Remove ELS ring handling leftovers from the lpfc_sli_inter().
|
||
|
|
* ELS ring (any slow ring) moved from the lpfc_sli_inter() into a
|
||
|
|
worker thread. Link Attention, Mbox Attention, and Error
|
||
|
|
Attention, as well as slow rings' attention is passed to the
|
||
|
|
worker thread via worker thread copy of Host Attention
|
||
|
|
register. Corresponding events are removed from the event queue
|
||
|
|
handling.
|
||
|
|
* Add entries to hba structure to delegate some functionality from
|
||
|
|
the lpfc_sli_inter() to a worker thread.
|
||
|
|
* Reduced used of GFP_ATOMIC for memory allocations.
|
||
|
|
* Moved locks deeper in order to change GFP_ATOMIC to GFP_KERNEL.
|
||
|
|
* IOCB initialization fix for Raw IO.
|
||
|
|
* Removed qcmdcnt, iodonecnt, errcnt from lpfc_target and from
|
||
|
|
driver.
|
||
|
|
* Added call to lpfc_els_abort in lpfc_free_node. Modified
|
||
|
|
lpfc_els_abort to reset txq and txcmplq iterator after a
|
||
|
|
iocb_cmpl call.
|
||
|
|
* Fixed a use after free issue in lpfc_init.c.
|
||
|
|
* Defined default mailbox completion routine and removed code in
|
||
|
|
the sli layer which checks the mbox_cmpl == 0 to free mail box
|
||
|
|
resources.
|
||
|
|
* In lpfc_workq_post_event, clean up comment formatting and remove
|
||
|
|
unneeded cast of kmalloc's return.
|
||
|
|
* Removed loop which calls fc_remote_port_unblock and
|
||
|
|
fc_remote_port_delete for every target as this same effect is
|
||
|
|
accomplished by the scsi_remove_host call.
|
||
|
|
* Minor cleanup of header files. Stop header files including
|
||
|
|
other header files. Removed sentinels which hide multiple
|
||
|
|
inclusions. Removed unneeded #include directives.
|
||
|
|
* Fixed memory leaks in mailbox error paths.
|
||
|
|
* Moved lock from around of lpfc_work_done to lpfc_work_done
|
||
|
|
itself.
|
||
|
|
* Removed typedef for LPFC_WORK_EVT_t and left just struct
|
||
|
|
lpfc_work_evt to comply with linux_scsi review coding style.
|
||
|
|
* Fixed some trailing whitespaces, spaces used for indentation and
|
||
|
|
ill-formatting multiline comments.
|
||
|
|
* Bug fix for Raw IO errors. Reuse of IOCBs now mandates setting
|
||
|
|
of ulpPU and fcpi_parm to avoid incorrect read check of Write IO
|
||
|
|
and incorrect read length.
|
||
|
|
|
||
|
|
Changes from 20050110 to 20050124
|
||
|
|
|
||
|
|
* Changed version number to 8.0.21
|
||
|
|
* Removed unpleasant casting in the definition and use of
|
||
|
|
lpfc_disc_action function pointer array.
|
||
|
|
* Makefile cleanup. Use ?= operator for setting default
|
||
|
|
KERNELVERSION and BASEINCLUDE values. Use $(PWD) consistently.
|
||
|
|
* Removed call to lpfc_sli_intr from lpfc_config_port_post. All
|
||
|
|
Linux systems will service hardware interrupts while bringing up
|
||
|
|
the driver.
|
||
|
|
* Christoph Hellwig change request: Reorg of contents of
|
||
|
|
lpfc_hbadisc.c, lpfc_scsi.h, lpfc_init.c, lpfc_sli.c,
|
||
|
|
lpfc_attr.c, lpfc_scsi.c.
|
||
|
|
* Renamed discovery thread to lpfc_worker thread. Moved handling
|
||
|
|
of error attention and link attention and mbox event handler to
|
||
|
|
lpfc_worker thread.
|
||
|
|
* Removed .proc_info and .proc_name from the driver template and
|
||
|
|
associated code.
|
||
|
|
* Removed check of FC_UNLOADING flag in lpfc_queuecommand to
|
||
|
|
determine what result to return.
|
||
|
|
* Move modification of FC_UNLOADING flag under host_lock.
|
||
|
|
* Fix IOERR_RCV_BUFFER_WAITING handling for CT and ELS subsystem.
|
||
|
|
* Workaround firmware bug for IOERR_RCV_BUFFER_WAITING on ELS
|
||
|
|
ring.
|
||
|
|
* Fixed a couple lpfc_post_buffer problems in lpfc_init.c.
|
||
|
|
* Add missing spaces to the parameter descriptions for
|
||
|
|
lpfc_cr_delay, lpfc_cr_count and lpfc_discovery_threads.
|
||
|
|
* Lock before calling lpfc_sli_hba_down().
|
||
|
|
* Fix leak of "host" in the error path in the remove_one() path.
|
||
|
|
* Fix comment for lpfc_cr_count. It defaults to 1.
|
||
|
|
* Fix issue where we are calling lpfc_disc_done() recursively from
|
||
|
|
lpfc_linkdown(), but list_for_each_entry_safe() is not safe for
|
||
|
|
such use.
|
||
|
|
* Bump lpfc_discovery_threads (count of outstading ELS commands in
|
||
|
|
discovery) to 32
|
||
|
|
* If the SCSI midlayer tries to recover from an error on a lun
|
||
|
|
while the corresponding target is in the NPR state, lpfc driver
|
||
|
|
will reject all the resets. This will cause the target to be
|
||
|
|
moved to offline state and block all the I/Os. The fix for this
|
||
|
|
is to delay the lun reset to a target which is not in MAPPED
|
||
|
|
state until the target is rediscovered or nodev timeout is
|
||
|
|
fired.

Changes from 20041229 to 20050110
|
||
|
|
|
||
|
|
* Changed version number to 8.0.20
|
||
|
|
* rport fix: use new fc_remote_port_rolechg() function instead of
|
||
|
|
direct structure change
|
||
|
|
* rport fix: last null pointer check
|
||
|
|
* Phase II of GFP_ATOMIC effort. Replaced iocb_mem_pool and
|
||
|
|
scsibuf_mem_pool with kmalloc and linked list. Inserted list
|
||
|
|
operations for mempool_alloc calls. General code cleanup. All
|
||
|
|
abort and reset routines converted. Handle_ring_event
|
||
|
|
converted.
|
||
|
|
* If the mbox_cmpl == lpfc_sli_wake_mbox_wait in
|
||
|
|
lpfc_sli_handle_mb_event, pmb->context1 points to a waitq. Do
|
||
|
|
not free the structure.
|
||
|
|
* rport fixes: fix for rmmod crash
|
||
|
|
* rport fixes: when receiving PRLI's, set node/rport role values
|
||
|
|
* rport fixes: fix for unload and for fabric port deletes
|
||
|
|
* VPD info bug fix.
|
||
|
|
* lpfc_linkdown() should be able to process all outstanding events
|
||
|
|
by calling lpfc_disc_done() even if it is called from
|
||
|
|
lpfc_disc_done() Moving all events from phba->dpc_disc to local
|
||
|
|
local_dpc_disc prevents those events from being processed.
|
||
|
|
Removing that queue. From now on we should not see "Illegal
|
||
|
|
State Transition" messages.
|
||
|
|
* Release host lock and enable interrupts when calling
|
||
|
|
del_timer_sync()
|
||
|
|
* All related to rports: Clean up issues with rport deletion
|
||
|
|
Convert to using block/unblock on list remove (was del/add)
|
||
|
|
Moved rport delete to freenode - so rport tracks node.
|
||
|
|
* rport fixes: for fport, get maxframe and class support
|
||
|
|
information
|
||
|
|
* Added use of wait_event to work with kthread interface.
|
||
|
|
* Ensure that scsi_transport_fc.h is always pulled in by
|
||
|
|
lpfc_scsiport.c
|
||
|
|
* In remote port changes: no longer nulling target->pnode when
|
||
|
|
removing from mapped list. Pnode get nulled when the node is
|
||
|
|
freed (after nodev tmo). This bug was causing i/o received in
|
||
|
|
the small window while the device was blocked to be errored w/
|
||
|
|
did_no_connect. With the fix, it returns host_busy
|
||
|
|
(per the pre-remote port changes).
|
||
|
|
* Merge in support for fc transport remote port use. This removes
|
||
|
|
any consistent bindings within the driver. All scanning is now
|
||
|
|
on a per-target basis driven by the discovery engine.
|
||
|
|
|
||
|
|
Changes from 20041220 to 20041229
|
||
|
|
|
||
|
|
* Changed version number to 8.0.19
|
||
|
|
* Fixed bug for handling RSCN type 3. Terminate RSCN mode
|
||
|
|
properly after ADISC handling completes.
|
||
|
|
* Add list_remove_head macro. Macro cleans up memory allocation
|
||
|
|
list handling. Also clean up lpfc_reset_bus_handler - routine
|
||
|
|
does not need to allocate its own scsi_cmnd and scsi_device
|
||
|
|
structures.
|
||
|
|
* Fixed potential discovery bug, nlp list corrutpion fix potential
|
||
|
|
memory leak
|
||
|
|
* Part 1 of the memory allocation rework request by linux-scsi.
|
||
|
|
This effort fixes the number of bdes per scsi_buf to 64, makes
|
||
|
|
the scatter-gather count a module parameter, builds a linked
|
||
|
|
list of scsi_bufs, and removes all dependencies on lpfc_mem.h.
|
||
|
|
* Reverted lpfc_do_dpc, probe_one, remove_one to original
|
||
|
|
implementation. Too many problems (driver not completing
|
||
|
|
initial discovery, and IO not starting to disks). Backs out
|
||
|
|
kthread patch.
|
||
|
|
* Fix race condition in lpfc_do_dpc. If wake_up interrupt occurs
|
||
|
|
while lpfc_do_dpc is running disc_done and the dpc list is
|
||
|
|
empty, the latest insertion is missed and the schedule_timeout
|
||
|
|
does not wakeup. The sleep interval is MAX_SCHEDULE_TIMEOUT
|
||
|
|
defined as ~0UL >> 1, a very large number. Hacked it to 5*HZ
|
||
|
|
for now.
|
||
|
|
* Fixed bug introduced when discovery thread implementation was
|
||
|
|
moved to kthread. kthread_stop() is not able to wake up thread
|
||
|
|
waiting on a semaphore and "modprobe -r lpfc" is not always
|
||
|
|
(most of the times) able to complete. Fix is in not using
|
||
|
|
semaphore for the interruptable sleep.
|
||
|
|
* Small Makefile cleanup - Remove remnants of 2.4 vs. 2.6
|
||
|
|
determination.
|
||
|
|
|
||
|
|
Changes from 20041213 to 20041220
|
||
|
|
|
||
|
|
* Changed version number to 8.0.18
|
||
|
|
* Janitorial cleanup after removal of sliinit and ringinit[] ring
|
||
|
|
statistic is owned by the ring and SLI stats are in sli
|
||
|
|
structure.
|
||
|
|
* Integrated patch from Christoph Hellwig <hch@lst.de> Kill
|
||
|
|
compile warnings on 64 bit platforms: %variables for %llx format
|
||
|
|
specifiers must be cast to long long because %(u)int64_t can
|
||
|
|
just be long on 64bit platforms.
|
||
|
|
* Integrated patch from Christoph Hellwig <hch@lst.de> Removes
|
||
|
|
dead code.
|
||
|
|
* Integrated patch from Christoph Hellwig <hch@lst.de>: use
|
||
|
|
kthread interface.
|
||
|
|
* Print LPFC_MODULE_DESC banner in module init routine.
|
||
|
|
* Removed sliinit structure and ringinit[] array.
|
||
|
|
* Changed log message number from 324 to 326 in lpfc_sli.c.
|
||
|
|
* Wait longer for commands to complete in lpfc_reset_bus_handler
|
||
|
|
and lpfc_reset_bus_handler. Also use schedule_timeout() instead
|
||
|
|
of msleep() and add error message in lpfc_abort_handler()
|
||
|
|
* When setting lpfc_nodev_tmo, from dev_loss set routine, make 1
|
||
|
|
sec minimum value.
|
||
|
|
* Functions which assume lock being held were called without lock
|
||
|
|
and kernel complained about unlocking lock which is not locked.
|
||
|
|
* Added code in linkdown to unreg if we know login session will be
|
||
|
|
terminated.
|
||
|
|
* Removed automap config parameter and fixed up use_adisc logic to
|
||
|
|
include FCP2 devices.
|
||
|
|
|
||
|
|
Changes from 20041207 to 20041213
|
||
|
|
|
||
|
|
* Changed version number to 8.0.17
|
||
|
|
* Fix sparse warnings by adding __iomem markers to lpfc_compat.h.
|
||
|
|
* Fix some sparse warnings -- 0 used as NULL pointer.
|
||
|
|
* Make sure there's a space between every if and it's (.
|
||
|
|
* Fix some overly long lines and make sure hard tabs are used for
|
||
|
|
indentation.
|
||
|
|
* Remove all trailing whitespace.
|
||
|
|
* Integrate Christoph Hellwig's patch for 8.0.14: if
|
||
|
|
pci_module_init fails we need to release the transport template.
|
||
|
|
(also don't print the driver name at startup, linux drivers can
|
||
|
|
be loaded without hardware present, and noise in the log for
|
||
|
|
that case is considered unpolite, better print messages only for
|
||
|
|
hardware actually found).
|
||
|
|
* Integrate Christoph Hellwig's patch for 8.0.14: Add missing
|
||
|
|
__iomem annotations, remove broken casts, mark functions static.
|
||
|
|
Only major changes is chaning of some offsets from word-based to
|
||
|
|
byte-based so we cans simply do void pointer arithmetics (gcc
|
||
|
|
extension) instead of casting to uint32_t.
|
||
|
|
* Integrate Christoph Hellwig's patch for 8.0.14: flag is always
|
||
|
|
LPFC_SLI_ABORT_IMED, aka 0 - remove dead code.
|
||
|
|
* Modified preprocessor #ifdef, #if, #ifndef to reflect upstream
|
||
|
|
kernel submission. Clean build with make clean;make and make
|
||
|
|
clean;make ADVANCED=1 on SMP x86, 2.6.10-rc2 on RHEL 4 Beta
|
||
|
|
1. IO with a few lips and a long cable pull behaved accordingly.
|
||
|
|
* Implement full VPD support.
|
||
|
|
* Abort handler will try to wait for abort completion before
|
||
|
|
returning. Fixes some panics in iocb completion code path.
|
||
|
|
|
||
|
|
Changes from 20041130 to 20041207
|
||
|
|
|
||
|
|
* Changed version number to 8.0.16
|
||
|
|
* Hung dt session fix. When the midlayer calls to abort a scsi
|
||
|
|
command, make sure the driver does not complete post-abort
|
||
|
|
handler. Just NULL the iocb_cmpl callback handler and let SLI
|
||
|
|
take over.
|
||
|
|
* Add Read check that uses SLI option to validate all READ data
|
||
|
|
actually received.
|
||
|
|
|
||
|
|
|
||
|
|
Changes from 20041123 to 20041130
|
||
|
|
|
||
|
|
* Changed version number to 8.0.15
|
||
|
|
* Ifdef'd unused "binary" attributes by DFC_DEBUG for clean
|
||
|
|
compiles
|
||
|
|
* Stop DID_ERROR from showing up along with QUEUE_FULL set by the
|
||
|
|
Clarion array (SCSI error ret. val. 0x70028) There is no need
|
||
|
|
for driver to hard fail command which was failed by the target
|
||
|
|
device.
|
||
|
|
* Fix for Scsi device scan bug reported on SourceForge. Driver
|
||
|
|
was returning a DID_ERROR in lpfc_handle_fcp_error causing
|
||
|
|
midlayer to mark report luns as failing even though it
|
||
|
|
succeeded.
|
||
|
|
* Don't ignore SCSI status on underrun conditions for inquiries,
|
||
|
|
test unit ready's, etc. This was causing us to lose
|
||
|
|
reservation conflicts, etc
|
||
|
|
|
||
|
|
Changes from 20041018 to 20041123
|
||
|
|
|
||
|
|
* Changed version number to 8.0.14
|
||
|
|
* Added new function "iterator" lpfc_sli_next_iocb_slot() which
|
||
|
|
returns pointer to iocb entry at cmdidx if queue is not full.
|
||
|
|
It also updates next_cmdidx, and local_getidx (but not cmdidx)
|
||
|
|
* lpfc_sli_submit_iocb() copies next_cmdidx into cmdidx. Now it is
|
||
|
|
the only place were we are updating cmdidx.
|
||
|
|
* lpfc_sli_update_ring() is split in to two --
|
||
|
|
lpfc_sli_update_ring() and lpfc_sli_update_full_ring().
|
||
|
|
* lpfc_sli_update_ring() don't to read back correct value of
|
||
|
|
cmdidx.
|
||
|
|
* Simplified lpfc_sli_resume_iocb() and its use.
|
||
|
|
* New static function lpfc_sli_next_iocb(phba, pring, &piocb) to
|
||
|
|
iterate through commands in the TX queue and new command (at the
|
||
|
|
end).
|
||
|
|
* Reduced max_lun to 256 (due to issues reported to some arrays).
|
||
|
|
Fixed comment, and macro values so def=256, min=1, max=32768.
|
||
|
|
* Fix an obvious typo/bug: kfree was used to free lpfc_scsi_buf
|
||
|
|
instead of mempool_free in lpfc_scsiport.c.
|
||
|
|
* Suppress nodev_tmo message for FABRIC nodes.
|
||
|
|
* Fixed some usage of plain integer as NULL pointer.
|
||
|
|
* Bug fix for FLOGI cmpl, lpfc_els_chk_latt error path code
|
||
|
|
cleanup.
|
||
|
|
* Fixup lpfc_els_chk_latt() to have Fabric NPorts go thru
|
||
|
|
discovery state machine as well.
|
||
|
|
* Fixes to lpfc_els_chk_latt().
|
||
|
|
* Use DID not SCSI target id as a port_id and add some missing
|
||
|
|
locks in lpfc_fcp.c.
|
||
|
|
* Changed eh_abort_handler to return FAILED if command is not
|
||
|
|
found in driver.
|
||
|
|
* Fix crash: paging request at virtual address 0000000000100108 -
|
||
|
|
a result of removing from the txcmpl list item which was already
|
||
|
|
removed (100100 is a LIST_POISON1 value from the next pointer
|
||
|
|
and 8 is an offset of the "prev") Driver runs out of iotags and
|
||
|
|
does not handle that case well. The root of the proble is in the
|
||
|
|
initialization code in lpfc_sli.c
|
||
|
|
* Changes to work with proposed linux kernel patch to support
|
||
|
|
hotplug.
|
||
|
|
* Zero out seg_cnt in prep_io failure path to prevent double sg
|
||
|
|
unmap calls.
|
||
|
|
* Fix setting of upper 32 bits for Host Group Ring Pointers if in
|
||
|
|
SLIM. Old code was inappropriately masking off low order bits.
|
||
|
|
* Use scsi_[activate|deactivate]_tcq calls provided in scsi_tcq.h.
|
||
|
|
* Integrated patch from Christoph Hellwig (hch@lst.de): don't call
|
||
|
|
pci_dma_sync_* on coherent memory. pci_dma_sync_* is need and
|
||
|
|
must be used only with streaming dma mappings pci_map_*, not
|
||
|
|
coherent mappings. Note: There are more consistent mappings
|
||
|
|
that are using pci_dma_sync calls. Probably these should be
|
||
|
|
removed as well.
|
||
|
|
* Modified lpfc_free_scsi_buf to accommodate all three scsi_buf
|
||
|
|
free types to alleviate miscellaneous panics with cable pull
|
||
|
|
testing.
|
||
|
|
* Set hotplug to default 0 and lpfc_target_remove to not remove
|
||
|
|
devices unless hotplug is enabled.
|
||
|
|
* Fixed discovery bug: plogi cmpl uses ndlp after its freed.
|
||
|
|
* Fixed discovery bug: rnid acc cmpl, can potentially use ndlp
|
||
|
|
after its freed.
|
||
|
|
* Modularize code path in lpfc_target_remove().
|
||
|
|
* Changes to support SCSI hotplug (ifdef'ed out because they need
|
||
|
|
kernel support USE_SCAN_TARGET requires kernel support to export
|
||
|
|
the interface to scsi_scan_target and to move the SCAN_WILD_CARD
|
||
|
|
define to a general scsi header file. USE_RESCAN_HOST requires
|
||
|
|
kernel support to export an interface to scan_scsi_host() with
|
||
|
|
the rescan flag turned on).
|
||
|
|
* Removed redundant variable declaration of lpfc_linkdown_tmo.
|
||
|
|
* Fix for large port count remove test.
|
||
|
|
* Added check to see if BAR1 register is valid before using BAR1
|
||
|
|
register for programming config_port mail box command.
|
||
|
|
* Added lpfc_scsi_hotplug to enable/disable driver support of SCSI
|
||
|
|
hotplug.
|
||
|
|
* Changed lpfc_disc_neverdev() to lpfc_disc_illegal() and changed
|
||
|
|
lpfc_disc_nodev() to lpfc_disc_noop(). Adjusted appropriate
|
||
|
|
events to use these routines.
|
||
|
|
* Add support for SCSI device hotplug.
|
||
|
|
* Take dummy lpfc_target's into account for lpfc_slave_destroy().
|
||
|
|
* Bug fix to store WWPN / WWNN in NameServer / FDMI lpfc_nodelist
|
||
|
|
entries.
|
||
|
|
* Added slavecnt in lpfc_target for diagnostic purposes.
|
||
|
|
* Added lpfc_hba load/unload flags to take care of special cases
|
||
|
|
for add/remove device.
|
||
|
|
* Have target add/remove delay before scanning.
|
||
|
|
* Have rmmod path cleanup blocked devices before scsi_remove_host.
|
||
|
|
* Added a #define for msleep for 2.6.5 kernels.
|
||
|
|
* In reset bus handler if memory allocation fails, return FAILED
|
||
|
|
and not SUCCESS.
|
||
|
|
* Have lpfc eh handlers, bus_reset and lun_reset, wait for all
|
||
|
|
associated I/Os to complete before returning.
|
||
|
|
* Fix memset byte count in lpfc_hba_init so that
|
||
|
|
LP1050 would initialize correctly.
|
||
|
|
* Backround nodev_timeout processing to DPC This enables us to
|
||
|
|
unblock (stop dev_loss_tmo) when appopriate.
|
||
|
|
* Fix array discovery with multiple luns. The max_luns was 0 at
|
||
|
|
the time the host structure was initialized. lpfc_cfg_params
|
||
|
|
then set the max_luns to the correct value afterwards.
|
||
|
|
* Remove unused define LPFC_MAX_LUN and set the default value of
|
||
|
|
lpfc_max_lun parameter to 512.
|
||
|
|
* Reduced stack usage of lpfc_hba_init.
|
||
|
|
* Cleaned up the following warning generated by
|
||
|
|
scripts/checkincludes.pl lpfc_fcp.c: scsi/scsi_cmnd.h is
|
||
|
|
included more than once.
|
||
|
|
* Replaced "set_current_state(TASK_UNINTERRUPTIBLE);
|
||
|
|
schedule_timeout(timeout)" with "msleep(timeout)".
|
||
|
|
* Fixnode was losing starget when rediscovered. We saw messages
|
||
|
|
like: lpfc 0000:04:02.0: 0:0263 Cannot block scsi target as a
|
||
|
|
result. Moved starget field into struct lpfc_target which is
|
||
|
|
referenced from the node.
|
||
|
|
* Add additional SLI layer logging in lpfc_sli.c.
|
||
|
|
* Ignore more unexpected completions in lpfc_nportdisc.c.
|
||
|
|
* Can not call lpfc_target_unblock from the soft interrupt
|
||
|
|
context. It seems to be not nessasery to unblock target from
|
||
|
|
nodev timeout.
|
||
|
|
* Introduce and use less lethal event handler for unexpected
|
||
|
|
events in lpfc_nportdisc.c.
|
||
|
|
* Can not call fc_target_(un)block() functions with interrupts
|
||
|
|
disabled in lpfc_scsiport.c.
|
||
|
|
* Added new configuration parameter, lpfc_max_luns range 1-32768,
|
||
|
|
default 32768.
|
||
|
|
* Allow lpfc_fcp.c to call lpfc_get_hba_sym_node_name().
|
||
|
|
* Increase nodev timeout from 20 seconds to 30 seconds.
|
||
|
|
* Replace some kfree((void*)ptr) with kfree(ptr).
|
||
|
|
* Make 3 functions static: lpfc_get_hba_sym_node_name,
|
||
|
|
lpfc_intr_prep and lpfc_setup_slim_access. Move lpfc_intr_prep
|
||
|
|
and lpfc_setup_slim_access so they're defined before being used.
|
||
|
|
* Remove an unnecessary list_del() in lpfc_hbadisc.c.
|
||
|
|
* Set nlp_state before calling lpfc_nlp_list() since this will
|
||
|
|
potentially call fc_target_unblock which may cause a race in
|
||
|
|
queuecommand by releasing host_lock.
|
||
|
|
* Since lpfc_nodev_tmo < dev_loss_tmo remove queuecommand
|
||
|
|
DID_BAD_TARGET return for now.
|
||
|
|
* Fix a problem with rcv logo.
|
||
|
|
* Remove unused portstatistics_t structure.
|
||
|
|
* Remove #if 0 and unnecessary checks in lpfc_fcp.c.
|
||
|
|
* Simplify lpfc_issue_lip: Extra layer of protection removed.
|
||
|
|
* Grab lock before calling lpfc_sli_issue_mbox(phba, pmb,
|
||
|
|
MBX_NOWAIT) in lpfc_sli_issue_mbox_wait().
|
||
|
|
|
||
|
|
Changes from 20040920 to 20041018
|
||
|
|
|
||
|
|
* Changed version number to 8.0.13
|
||
|
|
* Hide some attributes using #ifndef DFC_DEBUG ... #endif.
|
||
|
|
* Modify Makefile to (1) make BUILD_NO_DEBUG=1 will hide some
|
||
|
|
(binary) attributes (2) make BUILD_FC_TRANS=0 will build driver
|
||
|
|
for 2.6.5 kernel with block/unblock patch.
|
||
|
|
* Modified #ifdef names.
|
||
|
|
* Added support for proposed FC transport host attributes (which
|
||
|
|
replaces some of the attributes we had local to the driver).
|
||
|
|
Removed the binary statistics sysfs attribute.
|
||
|
|
* Added extra ELS verbose logging for ELS responses.
|
||
|
|
* Added recognition for BUILD_FC_TRANS=2 to Makefile to define
|
||
|
|
FC_TRANS_VER2.
|
||
|
|
* Add a pointer for link stats allocation.
|
||
|
|
* Exported lpfc_get_hba_sym_node_name for use by FC_TRANS_VER2
|
||
|
|
sysfs routines.
|
||
|
|
* Fix discovery problem in lip testing: if device sends an ELS cmd
|
||
|
|
(i.e. LOGO) before our FLOGI completes it should be LS_RJT'ed.
|
||
|
|
* Moved #defines around to provide target_add/remove for upstream
|
||
|
|
kernel deliverables only not SLES9. Provided ifdefs to #include
|
||
|
|
target_block/unblock only if FC_TRANS_VER1.
|
||
|
|
* Add sanity check in lpfc_nlp_list move setting nlp_Target
|
||
|
|
outside #ifdef.
|
||
|
|
* Added a blocked member to the lpfc_target structure for
|
||
|
|
block/unblock. This member allows the driver to know when to
|
||
|
|
unblock for pci_remove_one or pci_add_one. #ifdef'd some more
|
||
|
|
block/unblock stuff and removed some defensive checks from
|
||
|
|
target_block/unblock.
|
||
|
|
* Moved + 5 second window to dev_loss_tmo setting and updated
|
||
|
|
comments.
|
||
|
|
* Removed NULL target check from target_block/unblock and fixed up
|
||
|
|
a few comments.
|
||
|
|
* Enable sysfs attributes on 2.6.5 kernels and remove extra
|
||
|
|
compatibility code.
|
||
|
|
* Remove any and all trailing whitespace.
|
||
|
|
* Added message 0718 and return error when dma_map_single fails.
|
||
|
|
* Changed the fcpCntl2 commands to include an FCP_ prefix to get
|
||
|
|
rid of build warnings on later 2.6.9-rc kernels. Build
|
||
|
|
conflicts with scsi/scsi.h. Remove inclusions of scsi/scsi.h
|
||
|
|
from hbadisc.c, sli.c, and fcp.c since these modules had no
|
||
|
|
dependencies on scsi.h.
|
||
|
|
* Fixed a bug with RSCN handling. A RSCN received on one device,
|
||
|
|
shouldn't affect other devices not referenced by the RSCN.
|
||
|
|
* Moved #if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,6) to include
|
||
|
|
lpfc_jedec_to_ascii to prevent warning in SLES 9.
|
||
|
|
* Update Makefile to account for SLES 9 and scsi-target upstream
|
||
|
|
kernel.
|
||
|
|
* This checkin provides block/unblock hooks for the upstream scsi
|
||
|
|
target kernel and 2.6.5 on SLES9 SP1 with the block/unblock
|
||
|
|
patch.
|
||
|
|
* Discovery changes regarding setting targetp->pnode and
|
||
|
|
ndlp->nlp_Target Ensure fc_target_* routines are called properly
|
||
|
|
from discovery. Remove list_del's from lpfc_cleanup(). Ensure
|
||
|
|
all the lpfc_consistent_bind_* routines don't set any driver
|
||
|
|
structure objects.
|
||
|
|
* Fix for timeout of READ_LA or READ_SPARAM mailbox command
|
||
|
|
causing panic.
|
||
|
|
* Cleanup list_del()'s for Discovery ndlp lists.
|
||
|
|
* Bug fixes for some insmod/rmmod crashes, link down crashes and
|
||
|
|
device loss crashes.
|
||
|
|
* Removed NLP_SEARCH_DEQUE.
|
||
|
|
* Call lpfc_target_unblock only if the targetp is nonNull and with
|
||
|
|
the host_lock held.
|
||
|
|
* Added qcmdcnt back along with misc bug fixes to discovery.
|
||
|
|
* Changed tgt_io to outfcpio lpfc_fcp.c.
|
||
|
|
* Fixed errors caused by LIP and cable pulls both with and without
|
||
|
|
block/unblock patch.
|
||
|
|
* For now we have to call fc_target_unblock and fc_target_block
|
||
|
|
with interrupts enabled.
|
||
|
|
* Save seg_cnt from dma_map_sg. Save scatter-gather start address
|
||
|
|
and pass back to dma_unmap_sg in error with seg_cnt.
|
||
|
|
* Incorporating block/unblock calls into driver with ifdefs. This
|
||
|
|
change is supported by scsi-target-2.6 kernel and forward only.
|
||
|
|
* Merged in some discovery bug fixes and added tgt io counters.
|
||
|
|
* Added sysfs attributes/interfaces: read only attribute
|
||
|
|
"management_version" and write only attribute "issue_lip".
|
||
|
|
* Fix build on big endian machines: while #if was OK with
|
||
|
|
__BIG_ENDIAN which defined as 4321, __BIG_ENDIAN_BITFIELD has to
|
||
|
|
be tested with #ifdef because it does not have any value, it is
|
||
|
|
either defined or not.
|
||
|
|
* Add fabric_name and port_type attributes.
|
||
|
|
* Change mdelay to msleep. mdelay works, but wastefully uses cpu
|
||
|
|
resources without a lock held. Revert to msleep. Tested with
|
||
|
|
sg_reset for bus and three attached targets.
|
||
|
|
* Added the customary #ifndef...#define...#endif to
|
||
|
|
lpfc_version.h.
|
||
|
|
* Integrate patches from Christoph Hellwig: two new helpers common
|
||
|
|
to lpfc_sli_resume_iocb and lpfc_sli_issue_iocb - singificant
|
||
|
|
cleanup of those two functions - the unused SLI_IOCB_USE_TXQ is
|
||
|
|
gone - lpfc_sli_issue_iocb_wait loses its flags argument
|
||
|
|
totally.
|
||
|
|
* Fix in lpfc_sli.c: we can not store a 5 bit value in a 4-bit
|
||
|
|
field.
|
||
|
|
* Moved some routines out of lpfc_fcp.c into more appropriate
|
||
|
|
files.
|
||
|
|
* Whitespace cleanup: remove all trailing whitespace.
|
||
|
|
* Make lpfc_disc_ndlp_show static to lpfc_fcp.c.
|
||
|
|
* Remove leftover printk and replace some with
|
||
|
|
printk(KERN_WARNING)
|
||
|
|
* Trivial: fix a few long lines and a soft tab.
|
||
|
|
* Remove warnings generated by Sparse against driver (make
|
||
|
|
C=1). Mostly these are "using integer as pointer warnings"
|
||
|
|
i.e. use NULL instead of 0.
|
||
|
|
* Integrated patch from Christoph Hellwig: Quite a lot of changes
|
||
|
|
here, the most notable is that the phba->slim2p lpfc_dmabuf goes
|
||
|
|
away in favour of a typede pointer and a dma_addr_t. Due to the
|
||
|
|
typed pointer lots of the cast mess can go away, and while at it
|
||
|
|
I also replaced the messy SLI2_SLIM_t with a simple struct
|
||
|
|
lpfc2_sli2_slim that only contains the part of the union we care
|
||
|
|
about while using SLI2_SLIM_SIZE for all size calculations
|
||
|
|
directly.
|
||
|
|
* Integrated patch from Christoph Hellwig: This streamlines the
|
||
|
|
I/O completion path a little more, especially taking care of
|
||
|
|
fast-pathing the non-error case. Also removes tons of dead
|
||
|
|
members and defines from lpfc_scsi.h - e.g. lpfc_target is down
|
||
|
|
to nothing more than the lpfc_nodelist pointer.
|
||
|
|
* Added binary sysfs file to issue mbox commands
|
||
|
|
* Replaced #if __BIG_ENDIAN with #if __BIG_ENDIAN_BITFIELD for
|
||
|
|
compatibility with the user space applications.
|
||
|
|
* Decrease the amount of data in proc_info.
|
||
|
|
* Condense nodelist flag members.
|
||
|
|
* Expand INFO for discovery sysfs shost entries.
|
||
|
|
* Notify user if information exceeds 4k sysfs limit.
|
||
|
|
* Removed a bunch of unused #defines.
|
||
|
|
* Added initial sysfs discovery shost attributes.
|
||
|
|
* Remove unused #defines lpfc_disc.h.
|
||
|
|
* Fixed failMask nodelist settings.
|
||
|
|
* Cleanup some old comments / unused variables.
|
||
|
|
* Add LP101 to list of recognized adapters.
|
||
|
|
|
||
|
|
Changes from 20040908 to 20040920
|
||
|
|
|
||
|
|
* Changed version number to 8.0.12
|
||
|
|
* Removed used #defines: DEFAULT_PCI_LATENCY_CLOCKS and
|
||
|
|
PCI_LATENCY_VALUE from lpfc_hw.h.
|
||
|
|
* Changes to accommodate rnid.
|
||
|
|
* Fix RSCN handling so RSCN NS queries only effect NPorts found in
|
||
|
|
RSCN data.
|
||
|
|
* If we rcv a plogi on a NPort queued up for discovery, clear the
|
||
|
|
NLP_NPR_2B_DISC bit since rcv plogi logic will force NPort thru
|
||
|
|
discovery.
|
||
|
|
* Ensure lpfc_target is also cleaned up in lpfc_cleanup().
|
||
|
|
* Preliminary changes for block/unblock kernel API extensions in
|
||
|
|
progress with linux-scsi list. These are name changes and
|
||
|
|
prototype changes only.
|
||
|
|
* Added send_abts flag to lpfc_els_abort. For rcv LOGO when ADISC
|
||
|
|
sent, the XRI of the LOGO rcv'ed is the same as the ADISC
|
||
|
|
sent. Thus we cannot ABTS the ADISC before sending the LOGO ACC.
|
||
|
|
* Weed out some unused fc_flags. Add FC_DISC_TMO.
|
||
|
|
* board_online sysfs attribute added to support libdfc functions
|
||
|
|
InitDiagEnv and SetBrdEnv.
|
||
|
|
* Streamline code in lpfc_els_retry fixup abort case in
|
||
|
|
lpfc_els_timeout_handler().
|
||
|
|
* Flush discovery/ELS events when we bring SLI layer down.
|
||
|
|
* ctlreg and slimem binary attributes added to support libdfc
|
||
|
|
read/write mem/ctl functions.
|
||
|
|
* Integrated Christoph Hellwig's patch: Cleanup
|
||
|
|
lpfc_sli_ringpostbuf_get.
|
||
|
|
* Modified lpfc_slave_alloc and lpfc_slave_destroy to allocate and
|
||
|
|
free a dummy target pointer. This allows queuecommand to skip
|
||
|
|
the NULL target pointer check and avoid the console spam when
|
||
|
|
slave_alloc fails.
|
||
|
|
* Fix cfg_scan_down logic, it was reversed.
|
||
|
|
* Init list head ctrspbuflist.
|
||
|
|
* Change name of lpfc_driver_abort to lpfc_els_abort since it is
|
||
|
|
only valid for ELS ring.
|
||
|
|
* Remove unused third argument for lpfc_consistent_bind_get().
|
||
|
|
* Fix up iotag fields in lpfc_prep_els_iocb().
|
||
|
|
* Remove log message on code path triggered by lpfc_els_abort().
|
||
|
|
* Set host->unique_id in lpfc_fcp.c.
|
||
|
|
* Removed deadwood: lpfc_target.pHba not necessary anymore.
|
||
|
|
* Integrated patch from Christoph Hellwig: remove dead
|
||
|
|
SLI_IOCB_POLL handling.
|
||
|
|
* Integrated patch from Christoph Hellwig: Streamline I/O
|
||
|
|
submission and completion path a little.
|
||
|
|
* Remove unnecessary lpfc_brd_no. Ensure brd_no assignment is
|
||
|
|
unique.
|
||
|
|
* Removed unused MAX_FCP_LUN.
|
||
|
|
* Use mod_timer instead of add_timer for fdmi in lpfc_ct.c.
|
||
|
|
* Fixed misc discovery problems.
|
||
|
|
* Move stopping timers till just before lpfc_mem_free() call.
|
||
|
|
* Fix up NameServer reglogin error path.
|
||
|
|
* Cleanup possible outstanding discovery timers on rmmod.
|
||
|
|
* Fix discovery NPort to NPort pt2pt problem.
|
||
|
|
* Get rid of ip_tmofunc / scsi_tmofunc.
|
||
|
|
* Integrated patch from Christoph Hellwig:
|
||
|
|
lpfc_disc_done/lpfc_do_dpc cleanup - lpfc_disc_done can return
|
||
|
|
void - move lpfc_do_dpc and lpfc_disc_done to lpfc_hbadisc.c -
|
||
|
|
remove checking of list emptiness before calling lpfc_disc_done,
|
||
|
|
it handles the empty list case just fine and the additional
|
||
|
|
instructions cost less then the bustlocked spinlock operations.
|
||
|
|
* Integrated patch from Christoph Hellwig: This adds a new 64bit
|
||
|
|
counter instead, brd_no isn't reused anymore. Also some tiny
|
||
|
|
whitespace cleanups in surrounding code.
|
||
|
|
* Reorder functions in lpfc_els.c to remove need for prototypes.
|
||
|
|
* Removed unused prototypes from lpfc_crtn.h -
|
||
|
|
lpfc_ip_timeout_handler, lpfc_read_pci and lpfc_revoke.
|
||
|
|
* Removed some unused prototypes from lpfc_crtn.h -
|
||
|
|
lpfc_scsi_hba_reset, lpfc_scsi_issue_inqsn,
|
||
|
|
lpfc_scsi_issue_inqp0, lpfc_scsi_timeout_handler.
|
||
|
|
* Integrated patch from Christoph Hellwig: remove TRUE/FALSE
|
||
|
|
usage.
|
||
|
|
* Integrated patch from Christoph Hellwig: Remove unused function
|
||
|
|
prototypes lpfc_set_pkt_len and lpfc_get_pkt_data from
|
||
|
|
lpfc_crtn.h - fixes build warnings.
|
||
|
|
* Removed unused struct lpfc_dmabufip definition from lpfc_mem.h.
|
||
|
|
* Removed pre-2.6.5 MODULE_VERSION macro from lpfc_compat.h.
|
||
|
|
* Fixing missing static and removing dead code.
|
||
|
|
* Adding nodewwn, portwwn and portfcid shost attributes.
|
||
|
|
* Initial support for CT via sysfs. request payloads of size less
|
||
|
|
than PAGE_SIZE and rsp payloads of size PAGE_SIZE are supported.
|
||
|
|
Driver maintains a list of rsp's and passes back rsp's
|
||
|
|
corresponding to the pid of the calling process.
|
||
|
|
* Support for RefreshInformation, GetAdapterAttributes,
|
||
|
|
GetPortStatistics.
|
||
|
|
* Make nodev-tmo default to 20 seconds.
|
||
|
|
* Fix up some DSM error cases, unreg_login rpi where needed.
|
||
|
|
* Fix up comments for fc_target_block / fc_target_unblock.
|
||
|
|
* Fix up code for scsi_block_requests / scsi_unblock_requests.
|
||
|
|
* Add NLP_FCP_TARGET for nodeinfo support.
|
||
|
|
* Move suspend/resume in lpfc_nlp_list under appropriate case -
|
||
|
|
Used host_lock for DPC to avoid race (remove dpc_lock)
|
||
|
|
* Fix some corner cases for PLOGI receive - simplify error case
|
||
|
|
for cmpl_reglogin_reglogin_issue.
|
||
|
|
* Bug fix for ppc64 EEH MMIO panic - always do readl after
|
||
|
|
writel's of HBA registers to force flush.
|
||
|
|
* Get rid of initial static routine declarations in lpfc_hbadisc.c
|
||
|
|
and lpfc_els.c.
|
||
|
|
* Updates to discovery processing.
|
||
|
|
|
||
|
|
Changes from 20040823 to 20040908
|
||
|
|
|
||
|
|
* Changed version number to 8.0.11
|
||
|
|
* Removed persistent binding code.
|
||
|
|
* Display both ASC and ASCQ info.
|
||
|
|
* Fixed link down->up transitions when linkdown tmo expires. Fix
|
||
|
|
was in the defensive error checking at the start of
|
||
|
|
queuecommand.
|
||
|
|
* Removed lpfc_scsi_timeout_handler as this timer is no longer
|
||
|
|
required. The midlayer will exhaust retries and then call
|
||
|
|
lpfc_abort_handler, lpfc_reset_lun_handler, and
|
||
|
|
lpfc_reset_target_handler.
|
||
|
|
* Minimal support for SCSI flat space addressing/volume set
|
||
|
|
addressing. Use 16 bits of LUN address so that flat
|
||
|
|
addressing/VSA will work.
|
||
|
|
* Changed 2 occurrences of if( 1 != f(x)) to if(f(x) != 1)
|
||
|
|
* Drop include of lpfc_cfgparm.h.
|
||
|
|
* Reduce stack usage of lpfc_fdmi_cmd in lpfc_ct.c.
|
||
|
|
* Add minimum range checking property to /sys write/store
|
||
|
|
functions.
|
||
|
|
* Fix display of node_name and port_name via fc transport
|
||
|
|
attr.
|
||
|
|
* Removed biosparam code.
|
||
|
|
* Removed range checking. phba->config[] array elements are now
|
||
|
|
embedded into the hba struct. lpfc_config_setup() has been
|
||
|
|
removed.
|
||
|
|
* Collapsed lpfc_scsi_cmd_start into lpfc_queuecommand and cleaned
|
||
|
|
up combined routines.
|
||
|
|
* Removed unused prototypes myprint and
|
||
|
|
lpfc_sched_service_high_priority_queue.
|
||
|
|
* Removed unused function lpfc_nodev.
|
||
|
|
* Removed scsi_cmnd->timeout_per_command cancelation. SCSI midlayer
|
||
|
|
now times out all commands - FW is instructed to not timeout.
|
||
|
|
* Removed polling code from lpfc_scsi_cmd_start. Reorganized
|
||
|
|
queuecommand and cmd_start some.
|
||
|
|
|
||
|
|
Changes from 20040810 to 20040823
|
||
|
|
|
||
|
|
* Changed version number to 8.0.10
|
||
|
|
* Additional timer changes as per Arjan / Christoph's comments.
|
||
|
|
* Used mod_timer() instead of del_timer_sync() where appropriate.
|
||
|
|
* Fixed a use after free case (panic on 2.6.8.1 with
|
||
|
|
CONFIG_DEBUG_SLAB set).
|
||
|
|
* Fix compile warning in lpfc_fcp.c.
|
||
|
|
* Minor fix for log message, that prints unassigned brdno which is
|
||
|
|
zero.
|
||
|
|
* Move scsi_host_alloc() to the beginning of probe_one(). This
|
||
|
|
ensures that host_lock is available at later stages and also
|
||
|
|
avoids tons of unnecessary initializing if host_alloc()
|
||
|
|
fails.
|
||
|
|
* Removed else clause from lpfc_slave_configure that set
|
||
|
|
sdev->queue_depth. The driver informs the midlayer of its
|
||
|
|
setting in the template and only overrides if queue tagging is
|
||
|
|
enabled.
|
||
|
|
* Added PCI_DEVICE_ID_ZEPHYR and PCI_DEVICE_ID_ZFLY (Junior
|
||
|
|
Zephyr) support
|
||
|
|
|
||
|
|
Changes from 20040730 to 20040810
|
||
|
|
|
||
|
|
* Changed version number to 8.0.9
|
||
|
|
* Removed per HBA driver lock. Driver now uses the host->host_lock
|
||
|
|
* Restored support for the 2.6.5 kernel for those linux distributions
|
||
|
|
shipped with the 2.6.5 kernel.
|
||

|
||
|
|
"Re: [Emulex] Ready for next round. This patch cleans up the memory

|
||
|
|

|
code.
|
||
|
|
|
||
|
|
Changes from 20040709 to 20040716
|
||
|

|
|
little more readable.
|
||
|
|
* Remove redundant port_cmp != 2 check in if
|
||
|
|
(!port_cmp) { .... if (port_cmp != 2).... }
|
||
|
|
* Clock changes: removed struct clk_data and timerList.
|
||
|

|
||
|

|
||
|
|
* 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.

|
||
|
|
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.
|
||

|
||
|
|
lpfc_extra_io_tmo, lpfc_nodev_holdio, lpfc_delay_rsp_err,
|
||
|
|
lpfc_tgt_queue_depth and lpfc_check_cond_err.
|
||
|
|
* Clock changes consolidating timers, just in the struct lpfc_hba,
|
||
|
|
to get rid of clkData and pass only one argument to timeout
|
||
|
|
routine. Also, removing need for outstanding clock linked list
|
||
|
|
to stop these timers at rmmod.
|
||
|
|
* Move lpfc.conf contents into lpfc_fcp.c. Removing per adapter
|
||
|
|
attributes in favor of global attributes.
|
||
|
|
* Fix a potential null pointer reference of pmbuf in lpfc_ct.c.
|
||
|
|
* On reset_lun, issue LUN_RESET as opposed to ABORT_TASK_SET.
|
||
|
|
* Removed SCSI_REQ_TMO related code.
|
||
|
|
* Introducing two new defines LPFC_ATTR_R and LPFC_ATTR_RW that do
|
||
|
|
a module_param, MODULE_PARM_DESC, lpfc_param_show,
|
||
|
|
[lpfc_param_store] and CLASS_DEVICE_ATTRIBUTE.
|
||
|
|
* Properly clean up when allocation of a linked BDE fails in the
|
||
|
|
SCSI queuecommand path.
|
||
|
|
* Fail SCSI command if dma_map_sg call fails.
|
||
|

|
||
|
|
lpfc_sli_issue_iocb_wait_high_priority() and
|
||
|
|
lpfc_sli_issue_iocb_wait().
|
||
|
|
* Arranging lpfc_scsiport.c to follow style of use after
|
||
|
|
definition. This removes the need for the cruft of forward
|
||
|
|
declarations. Also removing a redundant #define ScsiResult as it
|
||
|
|
already available elsewhere.
|
||
|
|
* Applying "Streamline lpfc error handling" patch from Christoph
|
||
|
|
Hellwig (hch@infradead.org) with following modifications: fix
|
||
|
|
mem leaks, remove some misplaced code that need not be there,
|
||
|
|
print a message on exit (old code prints two (entry/exit)), make
|
||
|
|
ret values consistent (either 1/0 or SUCCESS/FAILURE), keep all
|
||
|
|
eh routines in a single file (lpfc_scsiport.c).
|
||
|
|
* Move contents of lpfc_module_param.h into lpfc_fcp.c.
|
||
|
|
* Changed sysfs attributes to CLASS_DEVICE_ATTRIBUTES (previously
|
||
|
|
DEVICE_ATTRIBUTES). They now appear in
|
||
|
|
/sys/class/scsi_host/hostx (previously in
|
||
|
|
/sys/bus/pci/drivers/lpfc/devx).
|
||
|
|
* Removed lpfc_syfs.h and lpfc_sysfs.c.
|
||
|
|
* Cleanup of config params. Throttle params have been removed.
|
||
|
|
max_lun has been removed. max_target is replaced with a #define,
|
||
|
|
lun_skip is removed. Remove ipfc config params and related
|
||
|
|
code.
|
||
|
|
* Changed DMABUF_t usage to struct lpfc_dmabuf.
|
||
|
|
* Downsizing iCfgParam structure to include a_string, a_low, a_hi
|
||
|
|
and a_default values only.
|
||
|
|
* Free SCSI buf safety memory pool on shutdown to eliminate memory
|
||
|
|
leak.
|
||
|
|
* Change lpfc_printf_log to a #define. Also include phba->brd_no
|
||
|
|
and newline in the print string rather than in the #define.
|
||
|
|
* Remove code that optionally locates Host Group Pointers in host
|
||
|
|
memory SLIM since this is no longer needed for PPC64, once
|
||
|
|
CONFIG_PORT uses HBA's view of its BAR0.
|
||
|
|
* Removed the forward declarations of the sli functions and
|
||
|
|
rearranging the code in lpfc_sli.c.
|
||
|
|
* Removed the preamble functionality from logging.
|
||
|
|
* Make lpfc_sli_hba_setup() return negative error codes on error
|
||
|
|
and correct the comment left over in lpfc_fcp.c
|
||
|
|
* Removed the lpfc_loadtime variable.
|
||
|
|
* Put a space between all ifs and their open parens '('.
|
||
|
|
* Change Studly_Caps LPFC_SCSI_BUF_t to struct lpfc_scsi_buf.
|
||
|
|
* Fixed insmod hang after hardware error.
|
||
|
|
* Relocated scsi_host alloc to before we enable the interrupt
|
||
|
|
handler
|
||
|
|
* Add .tmp_versions directory to Makefile clean target. This
|
||
|
|
directory is created in the 2.6.5+ build process (with Red Hat
|
||
|
|
kernels at least).
|
||
|
|
* Changing phba->config to kmalloc lpfc_icfgparam and not
|
||
|
|
*phba->config. This is manifesting itself as a panic in
|
||
|
|
pci_release_region().
|
||
|
|
* Fix for firmware download / board reset problem.
|
||
|
|
* Integrated patch from Christoph Hellwig (hch@infradead.org) to
|
||
|
|
reorganize and cleanup lpfc_fcp.c
|
||
|
|
* Don't abort commands immediately when there is an RSCN event to
|
||
|
|
give driver time to rediscover targets before the midlayer
|
||
|
|
retries the SCSI commands.
|
||
|
|
|
||
|
|
Changes from 20040604 to 20040614
|
||
|
|
|
||
|
|
* Changed version number to 8.0.4
|
||
|
|
* Removed lpfc_valid_lun function.
|
||
|
|
* Added scsi_buf safety pool to address scsi_buf failures in
|
||
|
|
queuecommand under low memory conditions. Allocations now come
|
||
|
|
from kmalloc initially, but if kmalloc fails, the allocation
|
||
|
|
comes from the safety pool.
|
||
|
|
* Modified lpfc_slave_alloc to only set the scsi_device->hostdata
|
||
|
|
pointer if the driver has discovered the target. This routine
|
||
|
|
always returns success now as well since no error ever occurs in
|
||
|
|
the alloc routine.
|
||
|
|
* Mask only info and warning messages. Print all error messages
|
||
|
|
irrespective of mask.
|
||
|
|
* Removing lpfc_log_chk_msg_disabled()
|
||
|
|
* Changed lpfc_printf_log to take struct lpfc_hba * directly
|
||
|
|
instead of a "board number".
|
||
|
|
* Convert dma_sync_single to pci_dma_sync_single_for_{device/cpu}.
|
||
|
|
* Implemented new style log messages. The message strings are now
|
||
|
|
embedded in the call to lpfc_printf_log.
|
||
|
|
* Decreased FLOGI discovery timeout to 20 seconds.
|
||
|
|
* On error in lpfc_pci_probe_one() return -1 and not 1.
|
||
|
|
* Allow for board numbers that are not sequential, paving the way
|
||
|
|
for hotplug support.
|
||
|
|
* scsi_add_host() can fail, so wrap it around in an if(). Also
|
||
|
|
initiate scsi_scan_host() after attaching the sysfs attributes.
|
||
|
|
* lpfc_release_version is used only in lpfc_ct.c, so move it there
|
||
|
|
and mark it as static.
|
||
|
|
* Removed lpfc_sleep_ms and replaced with mdelay or schedule calls
|
||
|
|
directly
|
||
|
|
* Removed all (struct list_head *) casts from clkData-related list
|
||
|
|
handling in list_add, list_del macros.
|
||
|
|
* Removed EXPORT_SYMBOLs.
|
||
|
|
* Removed LPFC_MIN_QFULL and lpfc_qthrottle_up.
|
||
|
|
* Replace LPFCSCSITARGET_t with struct lpfc_target.
|
||
|
|
* Replace LPFCSCSILUN_t with struct lpfc_lun.
|
||
|
|
* Remove unused struct declarations (fcPathId and fcRouteId) from
|
||
|
|
lpfc_scsi.h.
|
||
|
|
* Rewrite use of FC transport attributes.
|
||
|
|
* Fix crash when link is lost. This was due to lpfc_delay_iodone
|
||
|
|
calling list_del on an object that was never put on a list.
|
||
|
|
* Remove trailing spaces at the end of all lines.
|
||
|
|
* Set MAX_FCP_TARGET to 256 from 0xff. Set MAX_FCP_LUN and
|
||
|
|
MAX_FCP_CMDS to their decimal equivalents and updated
|
||
|
|
documentation.
|
||
|
|
|
||
|
|
Changes from 20040526 to 20040604
|
||
|
|
|
||
|
|
* Changed version number to 8.0.3
|
||
|
|
* Completed sysfs FC transport support.
|
||
|
|
* Removed unused fields in SCSI LUN and SCSI Target structures:
|
||
|
|
void *pTargetProto; void *pTargetOSEnv; void *pLunOSEnv;
|
||
|
|
* Modified list_for_each to list_for_each_entry. Modified
|
||
|
|
list_for_each_safe to list_for_each_entry_safe.
|
||
|
|
* Remove lpfc_dfc.h file.
|
||
|
|
* Changed pHba->phba, pCommand->pcmd
|
||
|
|
* Changed plogi_ndlp -> plogindlp, pos_tmp->postmp, pRsp->prsp,
|
||
|
|
pCmd->pcmd
|
||
|
|
* Changed pText -> ptext
|
||
|
|
* Changed p_tmp_buff -> ptmpbuff
|
||
|
|
* Changed pBufList -> pbuflist, pRsp -> prsp, pCmd -> pcmd
|
||
|
|
* Changed *pos_tmp -> *postmp, *p_mbuf -> *pmbuf
|
||
|
|
* Following changes are made to the SCSI fast path: Added
|
||
|
|
DMA_BUF_t member to the lpfc_scsi_buf_t. This will reduce a
|
||
|
|
memory allocation in the scsi fast path. Added check for
|
||
|
|
targetp == NULL in the scsi fast path. Increased number of
|
||
|
|
scatter gather entries in lpfc_scsi_dma_ext to 4 from 3 and
|
||
|
|
changed the size of lpfc_scsi_dma_ext to 264
|
||
|
|
* Fixing some missing static lpfc_nportdisc.c.
|
||
|
|
* Reordered #include lines so that lpfc.h doesn't have to #include
|
||
|
|
other header files.
|
||
|
|
* Remove lpfc_get_hba_sym_node_name() as a global EXPORT and make
|
||
|
|
it static.
|
||
|
|
* Move struct clk_data definition from lpfc_hw.h to lpfc_sli.h.
|
||
|
|
* Changed LPFC_IOCBQ_t to struct lpfc_iocbq.
|
||
|
|
* Changed LPFC_SLI_RING_t to struct lpfc_sli_ring.
|
||
|
|
* Changed LPFC_NODELIST_t to struct lpfc_nodelist.
|
||
|
|
* Rearranged lpfc_nportdisc.c by moving state machine array
|
||
|
|
(lpfc_disc_action) and the one function that uses it,
|
||
|
|
lpfc_disc_state_machine, to the end of the file, removing the
|
||
|
|
need for the raft of prototypes at the top.
|
||
|
|
* Changed LPFC_BINDLIST_t to struct lpfc_bindlist.
|
||
|
|
* Removed lpfc_issue_ct_rsp(), lpfc_sleep(), lpfc_add_bind(),
|
||
|
|
lpfc_del_bind(), lpfc_sli_wake_mbox_wait() and
|
||
|
|
lpfc_sli_issue_mbox_wait().
|
||
|
|
* Fixed a large number of overly-long lines.
|
||
|
|
* Fixed some discovery problems: Introduced deferred ndlp removal
|
||
|
|
when in DSM to avoid panic when in nested DMSs Fix NportId
|
||
|
|
fffc01 handling to not relogin after LOGO fixed handling of LOGO
|
||
|
|
on PLOGI issue.
|
||
|
|
* Changed SLI_CT_REQUEST to lpfc_sli_ct_request.
|
||
|
|

|
||
|
|

|
||
|
|
* Changed 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 lpfc_num_iocbs, lpfc_num_bufs module parameters

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.
|
||
|
|

|
||
|

|
||
|
|
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().
|
||
|
|

|
||
|

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

|
||
|
|
* Several locking improvements.
|

|
||
|
|
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
|

||
|
|
the caller.
|
||

|
||
|
|
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.

|
lpfc_DELAYMS.
|
||
|
|
* Remove duplicated prototypes from lpfc_crtn.h:
|
||
|

lpfc_config_port_prep, lpfc_config_port_post,
|
||
|
|
lpfc_hba_down_prep.
|
||
|
|
* Removed some unused export_symbols.
|
||
|
|

|
||
|
|
*/drivers/scsi.

|
||
|
|
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.
|
||
|

|
|
element could be deleted.
|
||

|
||
|
|
|

|
||
|
|
|
||
|
|
* Change lpfc_config_port_prep() to interpret word 4 of the DUMP
|
||
|
|
mbox response as a byte-count

|
* Add info attribute to sysfs
|
||
|

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

|
|
was causing an Oops on 2.6.5 kernel.
|
||
|
|
* Cleanup use of several gotos not used for error exit.
|
||
|
|
* Replace memcpy_toio() and memcpy_toio() with endian-dependent
|
||
|
|
lpfc_memcpy_to_slim() and lpfc_memcpy_from_slim() so that for
|
||
|
|
big endian hosts like PPC64, the SLIM is accessed 4 bytes at a
|
||
|
|
time instead of as a byte-stream.
|
||
|
|
|
||
|
|
Changes from 20040409 to 20040416
|
||
|
|
|
||
|
|
* The scsi_register and scsi_alloc_host OS calls can fail and
|
||
|
|
return a zero-valued host pointer. A ctrl-C on 2.6 kernels
|
||
|
|
during driver load will cause this and the driver to panic.
|
||
|
|
Fixed this bug. Also found a bug in the error_x handling with
|
||
|
|
lpfc_sli_hba_down - it was in the wrong place and the driver
|
||
|
|
lock was not held, but needed to be (in lpfc_linux_attach) Fixed
|
||
|
|
both. Did some minor comment clean up.
|
||
|
|
* Removed unwanted (void *) castings.
|
||
|
|
* Replace define of INVALID_PHYS, with kernel 2.6.5's
|
||
|
|
dma_mapping_error() and add a inline function for earlier
|
||
|
|
kernels. Remove lpfc_bad_scatterlist().
|
||
|
|
* Clean up formatting in hbaapi.h, lpfc.h, lpfc_cfgparm.h,
|
||
|
|
lpfc_crtn.h, lpfc_ct.c, lpfc_diag.h, lpfc_disc.h, lpfc_els.c,
|
||
|
|
lpfc_fcp.c, lpfc_hbadisc.c, lpfc_hw.h, lpfc_init.c,
|
||
|
|
lpfc_ipport.c, lpfc_logmsg.c, lpfc_logmsg.h and lpfc_scsiport.c
|
||
|
|
- mostly replacing groups of 8 spaces with hard tabs and keeping
|
||
|
|
lines to 80 column max..
|
||
|
|
* Removed LPFC_DRVR_LOCK call from lpfc_unblock_requests for 2.4
|
||
|
|
kernels. The lpfc_scsi_done routine already unlocks the driver
|
||
|
|
lock since it expects this lock to be held.
|
||
|
|
* Removed global lock capabilities from driver lock routines
|
||
|
|
* Remove SA_INTERRUPT flag from request_irq
|
||
|
|
* Move dma_addr_t cast inside of getPaddr macro as everywhere
|
||
|
|
getPaddr is used, the return is cast to dma_addr_t.
|
||
|
|
* Clean up formatting in lpfc_sli.c and lpfc_sysfs.c - mostly
|
||
|
|
replacing groups of 8 spaces with hard tabs and keeping lines
|
||
|
|
to 80 column max.
|
||
|
|
* Fix build for RHEL 2.1 BOOT kernels by always #including
|
||
|
|
interrupt.h in lpfc.h.
|
||
|
|
* Fix RHEL 3 build by #defining EXPORT_SYMTAB.
|
||
|
|
* Replace sprintf with snprintf in lpfc_proc_info.
|
||
|
|
* Fix build warnings on 2.6 kernels - remove no longer used calls
|
||
|
|
to character device initialization.
|
||
|
|
* Initial support code for discovery in tasklet conversion.
|
||
|
|
* Removing char interface and ioctl code.
|
||
|
|
* Change all elx prefixes to lpfc
|
||
|
|
* Replace lpfc_write_slim() & lpfc_read_slim() with memcpy_toio(),
|
||
|

memcpy_fromio(), writel() & readl().
|
||
|
|
|
||
|
|
Changes from 20040402 to 20040409
|
||
|
|
|
||
|
|
* Replaced lpfc_read_hbaregs_plus_offset and
|
||
|
|
lpfc_write_hbaregs_plus_offset functions with readl and writel.
|
||
|
|
* Get rid of long mdelay's in insmod path
|
||
|
|
* Changed the way our pci_device_id structures are initialized

||
|
|
* Replace lpfc_read/write_CA/HA/HC/HS with calls to readl() &
|
||
|
|
writel() directly.
|
||
|
|
* Increase SLI2_SLIM to 16K Increase cmd / rsp IOCBs accordingly
|
||
|
|
* Removed lpfc_els_chk_latt from the lpfc_config_post function.
|
||
|
|
lpfc_els_chk_latt will enable the link event interrupts when
|
||
|
|
flogi is pending which causes two discovery state machines
|
||
|
|
running parallelly.
|
||
|
|
* Add pci_disable_device to unload path.
|
||
|
|
* Move lpfc_sleep_event from lpfc_fcp.c to lpfc_util_ioctl.c
|
||
|
|
* Call dma_map_single() & pci_map_single() directly instead of via
|
||
|
|
macro lpfc_pci_map(). Allow address 0 for PPC64.
|
||
|
|
* Change sleep to uninterruptible in lpfc_sli_issue_icob_wait
|
||
|
|
because this function doesn't handle signals.
|
||
|
|

|
||
|
|
elx_wakeup to wake_up_interruptible
|
||
|
|
* Add function lpfc_get_os_nameversion and change
|
||
|
|
lpfc_get_OsNameVersion to lpfc_get_os_nameversion.
|
||
|
|
* Remove lpfc_get_OsNameVersion
|
||
|
|
* Change driver name to a consistent lpfc in every visible place.
|
||
|

|
||
|
|
* Remove functions lpfc_register_intr and lpfc_unregister_intr
|
||
|
|
* Fill in owner field in lpfc_ops file_operations struct and
|
||
|
|
remove now unnecessary open and close entry points.
|
||
|
|
* Change function name prefixes from elx_ to lpfc_
|
||
|
|

|
||
|
|
hipri_wait_queue and rsp_iocb in union

|
|
|

|
||
|
|
|
||
|
|
* Updated ChangeLog for 20040402 SourceForge drop.
|
||
|
|
* Use safe list iterator for ndlp list
|
||
|
|
* Added code to return NLP_STE_FREED_NODE from the discovery
|
||
|
|
state machine functions if the node is freed from the
|
||
|
|
function.
|
||
|
|
* Fixes to DMABUF_t handling
|
||
|
|
* Fix for load error in discovery
|
||
|
|
* Remove loop_cnt variable from lpfc_rcv_plogi_unused_node.
|
||
|
|
* Remove nle. reference.
|
||
|
|
* Remove support for building 2.4 drivers
|
||
|
|
* Remove elx_util.h and replace elx_disc.h with lpfc_disc.h
|
||
|
|
* Implemented the Linux list macros in the discovery code.
|
||
|
|
Also moved elx_disc.h contents into lpfc_disc.h
|
||
|
|
* Unused variable cleanup
|
||
|
|
* Use Linux list macros for DMABUF_t
|
||
|
|
* Break up ioctls into 3 sections, dfc, util, hbaapi
|
||
|
|
rearranged code so this could be easily separated into a
|
||
|
|
differnet module later All 3 are currently turned on by
|
||
|
|
defines in lpfc_ioctl.c LPFC_DFC_IOCTL, LPFC_UTIL_IOCTL,
|
||
|
|
LPFC_HBAAPI_IOCTL
|
||
|
|
* Misc cleanup: some goto's; add comments; clarify function
|
||
|
|
args
|
||
|
|
* Added code to use list macro for ELXSCSITARGET_t.
|
||
|
|
* New list implementation for ELX_MBOXQ_t
|
||
|
|
* Cleaned up some list_head casting.
|

|
||
|
|
* 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

|
* 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.

|
||
|
|
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).
|
||
|
|

|
||
|
|
* 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

||
|
|
* Minor format changes fix up comments
|
||
|
|
* Create utility clock function elx_start_timer() and
|

|
|
routines.

|
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.

build. Uses the kernel build's definitions of CFLAGS,
|
||
|
|
MODFLAGS etc. Removed "make rpm" option.
|
||
