1282 Current Version : 00.00.04.31-rc1
1293 Older Version   : 00.00.04.17.1-rc1
130
1311.	Add the Online Controller Reset (OCR) to the Driver.
132	OCR is the new feature for megaraid_sas driver which
133	will allow the fw to do the chip reset which will not
134	affact the OS behavious.
135
136	To add the OCR support, driver need to do:
137		a). reset the controller chips -- Xscale and Gen2 which
138		will change the function calls and add the reset function
139		related to this two chips.
140
141		b). during the reset, driver will store the pending cmds
142		which not returned by FW to driver's pending queue.  Driver
143		will re-issue those pending cmds again to FW after the OCR
144		finished.
145
146		c). In driver's timeout routine, driver will report to
147		OS as reset. Also driver's queue routine will block the
148		cmds until the OCR finished.
149
150		d). in Driver's ISR routine, if driver get the FW state as
151		state change, FW in Failure status and FW support online controller
152		reset (OCR), driver will start to do the controller reset.
153
154		e). In driver's IOCTL routine, the application cmds will wait for the
155		OCR to finish, then issue the cmds to FW.
156
157		f). Before driver kill adapter, driver will do last chance of
158		OCR to see if driver can bring back the FW.
159
1602.	Add the support update flag to the driver to tell LSI megaraid_sas
161	application which driver will support the device update.  So application
162	will not need to do the device update after application add/del the device
163	from the system.
1643.	In driver's timeout routine, driver will do three time reset if fw is in
165	failed state.  Driver will kill adapter if can't bring back FW after the
166	this three times reset.
1674.	Add the input parameter max_sectors to 1MB support to our GEN2 controller.
168	customer can use the input paramenter max_sectors to add 1MB support to GEN2
169	controller.

179	context value larger than 32bit value issue.
180
1812.	Add the logic drive list to the driver.  Driver will
182	keep the logic drive list internal after driver load.
183
1843.	driver fixed the device update issue after get the AEN
185	PD delete/ADD, LD add/delete from FW.

3131. Added module parameter "poll_mode_io" to support for "polling"
314	(reduced interrupt operation).  In this mode, IO completion
315	interrupts are delayed. At the end of initiating IOs, the
316	driver schedules for cmd completion if there are pending cmds
317	to be completed.  A timer-based interrupt has also been added
318	to prevent IO completion processing from being delayed
319	indefinitely in the case that no new IOs are initiated.

3291. Setting the max_sectors_per_req based on max SGL supported by the
330	FW. Prior versions calculated this value from controller info
331	(max_sectors_1, max_sectors_2). For certain controllers/FW,
332	this was resulting in a value greater than max SGL supported
333	by the FW. Issue was first reported by users running LUKS+XFS
334	with megaraid_sas.  Thanks to RB for providing the logs and
335	duplication steps that helped to get to the root cause of the
336	issue.  2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
337	10. FW may take a max of 60 seconds to respond to the INIT
338	cmd.

392	It does, but the DMA API was expanded to cope with this exact case, so
393	use dma_alloc_coherent() directly in the megaraid code instead.  The dev
394	is just &pci_dev->dev.

4203 Older Version   : 00.00.03.07
421
422i.	Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
423
424	Fix:	The driver is now throttling IO.
425	Checks added in megasas_queue_command to know if FW is able to
426	process commands within timeout period. If number of retries
427	is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
428	resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
429	from the time cmds were last sent to FW.
430
431ii.	FW enables WCE bit in Mode Sense cmd for drives that are configured
432	as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
433	Disks are exposed with WCE=1. User is advised to enable Write Back
434	mode only when the controller has battery backup. At this time
435	Synhronize cache is not supported by the FW. Driver will short-cycle
436	the cmd and return success without sending down to FW.

4501. Added new memory management module to support the IOCTL memory allocation. For IOCTL we try to allocate from the memory pool created during driver initialization. If mem pool is empty then we allocate at run time.
4512. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
452   (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

458i.	PCI_DEVICE macro used
459
460	Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.
461

463ii.	All compiler warnings removed
464iii.	megasas_ctrl_info struct reverted to 3.02 release
465iv.	Default value of megasas_dbg_lvl set to 0
466v.	Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
467vi.	In megasas_teardown_frame_pool(), cmd->frame was passed instead of
468	cmd->sense to pci_pool_free. Fixed. Bug was pointed out by
469	Eric Sesterhenn

476ii.	Reduced by 1 max cmds sent to FW from Driver to make the reply_q_sz same
477	as Max Cmds FW can support

482
483i.	Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
484	New varible added to set dbg level.
485ii.	Disable interrupt made as fn pointer as they are different for 1068 / 1078
486iii.	Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
487	3 SGE for 32 bit SGL
488iv.	Tasklet added for cmd completion
489v.	If FW in operational state before firing INIT, now we send RESET Flag to FW instead of just READY. This is used to do soft reset.
490vi.	megasas_ctrl_prop structure updated (based on FW struct)
491vii.	Added print : FW now in Ready State during initialization

504
505		New device id 0x413 added.
506
507ii.	Bug fix : Disable controller interrupt before firing INIT cmd to FW.
508
509		Interrupt is enabled after required initialization is over.
510		This is done to ensure that driver is ready to handle interrupts when
511		it is generated by the controller.

533	are initialized with function pointers specific to the ppc or
534	xscale controllers.

543
544	"This patch properly registers the 16 byte command length capability of the
545	megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas
546	hardware supports 16 byte CDB's."

554i.	New template defined to represent each family of controllers (identified by processor used).
555	The template will have defintions that will be initialised to appropritae values for a specific family of controllers. The template definition has four function pointers. During driver initialisation the function pointers will be set based on the controller family type. This change is done to support new controllers that has different processors and thus different register set.
