87	2 Current Version : 00.00.04.31-rc1
88	3 Older Version   : 00.00.04.17.1-rc1
89	
90	1.	Add the Online Controller Reset (OCR) to the Driver.
91		OCR is the new feature for megaraid_sas driver which
92		will allow the fw to do the chip reset which will not
93		affact the OS behavious.
94	
95		To add the OCR support, driver need to do:
96			a). reset the controller chips -- Xscale and Gen2 which
97			will change the function calls and add the reset function
98			related to this two chips.
99	
100			b). during the reset, driver will store the pending cmds
101			which not returned by FW to driver's pending queue.  Driver
102			will re-issue those pending cmds again to FW after the OCR
103			finished.
104	
105			c). In driver's timeout routine, driver will report to
106			OS as reset. Also driver's queue routine will block the
107			cmds until the OCR finished.
108	
109			d). in Driver's ISR routine, if driver get the FW state as
110			state change, FW in Failure status and FW support online controller
111			reset (OCR), driver will start to do the controller reset.
112	
113			e). In driver's IOCTL routine, the application cmds will wait for the
114			OCR to finish, then issue the cmds to FW.
115	
116			f). Before driver kill adapter, driver will do last chance of
117			OCR to see if driver can bring back the FW.
118	
119	2.	Add the support update flag to the driver to tell LSI megaraid_sas
120		application which driver will support the device update.  So application
121		will not need to do the device update after application add/del the device
122		from the system.
123	3.	In driver's timeout routine, driver will do three time reset if fw is in
124		failed state.  Driver will kill adapter if can't bring back FW after the
125		this three times reset.
126	4.	Add the input parameter max_sectors to 1MB support to our GEN2 controller.
127		customer can use the input paramenter max_sectors to add 1MB support to GEN2
128		controller.

137	1.	Add the pad_0 in mfi frame structure to 0 to fix the
138		context value larger than 32bit value issue.
139	
140	2.	Add the logic drive list to the driver.  Driver will
141		keep the logic drive list internal after driver load.
142	
143	3.	driver fixed the device update issue after get the AEN
144		PD delete/ADD, LD add/delete from FW.

240		Sense buffer ptr data type in the ioctl path is reverted back
241		to u32 * as in previous versions of driver.
242	
243	2. Fixed the driver frame count.
244		When Driver sent wrong frame count to firmware.  As this
245		particular command is sent to drive, FW is seeing continuous
246		chip resets and so the command will timeout.
247	
248	3. Add the new controller(1078DE) support to the driver
249		and Increase the max_wait to 60 from 10 in the controller
250		operational status.  With this max_wait increase, driver will
251		make sure the FW will 	finish the pending cmd for KDUMP case.

271	
272	1. Added module parameter "poll_mode_io" to support for "polling"
273		(reduced interrupt operation).  In this mode, IO completion
274		interrupts are delayed. At the end of initiating IOs, the
275		driver schedules for cmd completion if there are pending cmds
276		to be completed.  A timer-based interrupt has also been added
277		to prevent IO completion processing from being delayed
278		indefinitely in the case that no new IOs are initiated.

287	
288	1. Setting the max_sectors_per_req based on max SGL supported by the
289		FW. Prior versions calculated this value from controller info
290		(max_sectors_1, max_sectors_2). For certain controllers/FW,
291		this was resulting in a value greater than max SGL supported
292		by the FW. Issue was first reported by users running LUKS+XFS
293		with megaraid_sas.  Thanks to RB for providing the logs and
294		duplication steps that helped to get to the root cause of the
295		issue.  2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
296		10. FW may take a max of 60 seconds to respond to the INIT
297		cmd.

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

356	
357		3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.
358		4. Hibernation support added
359		5. Performing diskdump while running IO in RHEL 4 was failing. Fixed.

380	
381	i.	Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
382	
383		Fix:	The driver is now throttling IO.
384		Checks added in megasas_queue_command to know if FW is able to
385		process commands within timeout period. If number of retries
386		is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
387		resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
388		from the time cmds were last sent to FW.
389	
390	ii.	FW enables WCE bit in Mode Sense cmd for drives that are configured
391		as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
392		Disks are exposed with WCE=1. User is advised to enable Write Back
393		mode only when the controller has battery backup. At this time
394		Synhronize cache is not supported by the FW. Driver will short-cycle
395		the cmd and return success without sending down to FW.

409	1. 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.
410	2. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
411	   (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

416	
417	i.	PCI_DEVICE macro used
418	
419		Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.
420	
421			- Henrik Kretzschmar <henne@nachtwindheim.de>
422	ii.	All compiler warnings removed
423	iii.	megasas_ctrl_info struct reverted to 3.02 release
424	iv.	Default value of megasas_dbg_lvl set to 0
425	v.	Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
426	vi.	In megasas_teardown_frame_pool(), cmd->frame was passed instead of
427		cmd->sense to pci_pool_free. Fixed. Bug was pointed out by
428		Eric Sesterhenn

433	
434	i.	Added Reboot notify
435	ii.	Reduced by 1 max cmds sent to FW from Driver to make the reply_q_sz same
436		as Max Cmds FW can support

439	2 Current Version : 00.00.03.03
440	3 Older Version   : 00.00.03.02
441	
442	i.	Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
443		New varible added to set dbg level.
444	ii.	Disable interrupt made as fn pointer as they are different for 1068 / 1078
445	iii.	Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
446		3 SGE for 32 bit SGL
447	iv.	Tasklet added for cmd completion
448	v.	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.
449	vi.	megasas_ctrl_prop structure updated (based on FW struct)
450	vii.	Added print : FW now in Ready State during initialization

462	i.	Added support for ZCR controller.
463	
464			New device id 0x413 added.
465	
466	ii.	Bug fix : Disable controller interrupt before firing INIT cmd to FW.
467	
468			Interrupt is enabled after required initialization is over.
469			This is done to ensure that driver is ready to handle interrupts when
470			it is generated by the controller.

491		During initialization, depending on the device id, the template members 
492		are initialized with function pointers specific to the ppc or 
493		xscale controllers.

513	i.	New template defined to represent each family of controllers (identified by processor used). 
514		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.

529	
530		"MEGASAS_IOC_FIRMWARE can't be redefined if CONFIG_COMPAT is set, we need to define a MEGASAS_IOC_FIRMWARE32 define so native binaries continue to work"
