196	2 Current Version : 00.00.04.31-rc1
197	3 Older Version   : 00.00.04.17.1-rc1
198	
199	1.	Add the Online Controller Reset (OCR) to the Driver.
200		OCR is the new feature for megaraid_sas driver which
201		will allow the fw to do the chip reset which will not
202		affact the OS behavious.
203	
204		To add the OCR support, driver need to do:
205			a). reset the controller chips -- Xscale and Gen2 which
206			will change the function calls and add the reset function
207			related to this two chips.
208	
209			b). during the reset, driver will store the pending cmds
210			which not returned by FW to driver's pending queue.  Driver
211			will re-issue those pending cmds again to FW after the OCR
212			finished.
213	
214			c). In driver's timeout routine, driver will report to
215			OS as reset. Also driver's queue routine will block the
216			cmds until the OCR finished.
217	
218			d). in Driver's ISR routine, if driver get the FW state as
219			state change, FW in Failure status and FW support online controller
220			reset (OCR), driver will start to do the controller reset.
221	
222			e). In driver's IOCTL routine, the application cmds will wait for the
223			OCR to finish, then issue the cmds to FW.
224	
225			f). Before driver kill adapter, driver will do last chance of
226			OCR to see if driver can bring back the FW.
227	
228	2.	Add the support update flag to the driver to tell LSI megaraid_sas
229		application which driver will support the device update.  So application
230		will not need to do the device update after application add/del the device
231		from the system.
232	3.	In driver's timeout routine, driver will do three time reset if fw is in
233		failed state.  Driver will kill adapter if can't bring back FW after the
234		this three times reset.
235	4.	Add the input parameter max_sectors to 1MB support to our GEN2 controller.
236		customer can use the input paramenter max_sectors to add 1MB support to GEN2
237		controller.

245	
246	1.	Add the pad_0 in mfi frame structure to 0 to fix the
247		context value larger than 32bit value issue.
248	
249	2.	Add the logic drive list to the driver.  Driver will
250		keep the logic drive list internal after driver load.
251	
252	3.	driver fixed the device update issue after get the AEN
253		PD delete/ADD, LD add/delete from FW.

347	
348	1. Rollback the sense info implementation
349		Sense buffer ptr data type in the ioctl path is reverted back
350		to u32 * as in previous versions of driver.
351	
352	2. Fixed the driver frame count.
353		When Driver sent wrong frame count to firmware.  As this
354		particular command is sent to drive, FW is seeing continuous
355		chip resets and so the command will timeout.
356	
357	3. Add the new controller(1078DE) support to the driver
358		and Increase the max_wait to 60 from 10 in the controller
359		operational status.  With this max_wait increase, driver will
360		make sure the FW will 	finish the pending cmd for KDUMP case.

381	1. Added module parameter "poll_mode_io" to support for "polling"
382		(reduced interrupt operation).  In this mode, IO completion
383		interrupts are delayed. At the end of initiating IOs, the
384		driver schedules for cmd completion if there are pending cmds
385		to be completed.  A timer-based interrupt has also been added
386		to prevent IO completion processing from being delayed
387		indefinitely in the case that no new IOs are initiated.

396	
397	1. Setting the max_sectors_per_req based on max SGL supported by the
398		FW. Prior versions calculated this value from controller info
399		(max_sectors_1, max_sectors_2). For certain controllers/FW,
400		this was resulting in a value greater than max SGL supported
401		by the FW. Issue was first reported by users running LUKS+XFS
402		with megaraid_sas.  Thanks to RB for providing the logs and
403		duplication steps that helped to get to the root cause of the
404		issue.  2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
405		10. FW may take a max of 60 seconds to respond to the INIT
406		cmd.

433	
434	1.  When MegaSAS driver receives reset call from OS, driver waits in reset
435	routine for max 3 minutes for all pending command completion. Now driver will
436	call completion routine every 5 seconds from the reset routine instead of
437	waiting for depending on cmd completion from isr path.

447		1. Memory Manager for IOCTL removed for 2.6 kernels.
448		   pci_alloc_consistent replaced by dma_alloc_coherent. With this
449		   change there is no need of memory manager in the driver code

459	
460		It does, but the DMA API was expanded to cope with this exact case, so
461		use dma_alloc_coherent() directly in the megaraid code instead.  The dev
462		is just &pci_dev->dev.
463	
464		James <James.Bottomley@SteelEye.com>
465	
466		3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.
467		4. Hibernation support added
468		5. Performing diskdump while running IO in RHEL 4 was failing. Fixed.

477	
478	i.	Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
479	
480		The driver now waits for 10 seconds to elapse instead of 5 (as in
481		previous release) to resume IO.

489	
490	i.	Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
491	
492		Fix:	The driver is now throttling IO.
493		Checks added in megasas_queue_command to know if FW is able to
494		process commands within timeout period. If number of retries
495		is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
496		resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
497		from the time cmds were last sent to FW.
498	
499	ii.	FW enables WCE bit in Mode Sense cmd for drives that are configured
500		as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
501		Disks are exposed with WCE=1. User is advised to enable Write Back
502		mode only when the controller has battery backup. At this time
503		Synhronize cache is not supported by the FW. Driver will short-cycle
504		the cmd and return success without sending down to FW.

516	3 Older Version   : 00.00.03.05
517	
518	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.
519	2. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
520	   (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

528		Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.
529	
530			- Henrik Kretzschmar <henne@nachtwindheim.de>
531	ii.	All compiler warnings removed
532	iii.	megasas_ctrl_info struct reverted to 3.02 release
533	iv.	Default value of megasas_dbg_lvl set to 0
534	v.	Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
535	vi.	In megasas_teardown_frame_pool(), cmd->frame was passed instead of
536		cmd->sense to pci_pool_free. Fixed. Bug was pointed out by
537		Eric Sesterhenn

551	i.	Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
552		New varible added to set dbg level.
553	ii.	Disable interrupt made as fn pointer as they are different for 1068 / 1078
554	iii.	Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
555		3 SGE for 32 bit SGL
556	iv.	Tasklet added for cmd completion
557	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.
558	vi.	megasas_ctrl_prop structure updated (based on FW struct)
559	vii.	Added print : FW now in Ready State during initialization

572	
573			New device id 0x413 added.
574	
575	ii.	Bug fix : Disable controller interrupt before firing INIT cmd to FW.
576	
577			Interrupt is enabled after required initialization is over.
578			This is done to ensure that driver is ready to handle interrupts when
579			it is generated by the controller.

623		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.
