169	2 Current Version : 00.00.04.31-rc1
170	3 Older Version   : 00.00.04.17.1-rc1
171	
172	1.	Add the Online Controller Reset (OCR) to the Driver.
173		OCR is the new feature for megaraid_sas driver which
174		will allow the fw to do the chip reset which will not
175		affact the OS behavious.
176	
177		To add the OCR support, driver need to do:
178			a). reset the controller chips -- Xscale and Gen2 which
179			will change the function calls and add the reset function
180			related to this two chips.
181	
182			b). during the reset, driver will store the pending cmds
183			which not returned by FW to driver's pending queue.  Driver
184			will re-issue those pending cmds again to FW after the OCR
185			finished.
186	
187			c). In driver's timeout routine, driver will report to
188			OS as reset. Also driver's queue routine will block the
189			cmds until the OCR finished.
190	
191			d). in Driver's ISR routine, if driver get the FW state as
192			state change, FW in Failure status and FW support online controller
193			reset (OCR), driver will start to do the controller reset.
194	
195			e). In driver's IOCTL routine, the application cmds will wait for the
196			OCR to finish, then issue the cmds to FW.
197	
198			f). Before driver kill adapter, driver will do last chance of
199			OCR to see if driver can bring back the FW.
200	
201	2.	Add the support update flag to the driver to tell LSI megaraid_sas
202		application which driver will support the device update.  So application
203		will not need to do the device update after application add/del the device
204		from the system.
205	3.	In driver's timeout routine, driver will do three time reset if fw is in
206		failed state.  Driver will kill adapter if can't bring back FW after the
207		this three times reset.
208	4.	Add the input parameter max_sectors to 1MB support to our GEN2 controller.
209		customer can use the input paramenter max_sectors to add 1MB support to GEN2
210		controller.

218	
219	1.	Add the pad_0 in mfi frame structure to 0 to fix the
220		context value larger than 32bit value issue.
221	
222	2.	Add the logic drive list to the driver.  Driver will
223		keep the logic drive list internal after driver load.
224	
225	3.	driver fixed the device update issue after get the AEN
226		PD delete/ADD, LD add/delete from FW.

324	
325	2. Fixed the driver frame count.
326		When Driver sent wrong frame count to firmware.  As this
327		particular command is sent to drive, FW is seeing continuous
328		chip resets and so the command will timeout.
329	
330	3. Add the new controller(1078DE) support to the driver
331		and Increase the max_wait to 60 from 10 in the controller
332		operational status.  With this max_wait increase, driver will
333		make sure the FW will 	finish the pending cmd for KDUMP case.

353	
354	1. Added module parameter "poll_mode_io" to support for "polling"
355		(reduced interrupt operation).  In this mode, IO completion
356		interrupts are delayed. At the end of initiating IOs, the
357		driver schedules for cmd completion if there are pending cmds
358		to be completed.  A timer-based interrupt has also been added
359		to prevent IO completion processing from being delayed
360		indefinitely in the case that no new IOs are initiated.

369	
370	1. Setting the max_sectors_per_req based on max SGL supported by the
371		FW. Prior versions calculated this value from controller info
372		(max_sectors_1, max_sectors_2). For certain controllers/FW,
373		this was resulting in a value greater than max SGL supported
374		by the FW. Issue was first reported by users running LUKS+XFS
375		with megaraid_sas.  Thanks to RB for providing the logs and
376		duplication steps that helped to get to the root cause of the
377		issue.  2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
378		10. FW may take a max of 60 seconds to respond to the INIT
379		cmd.

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

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

432	
433		It does, but the DMA API was expanded to cope with this exact case, so
434		use dma_alloc_coherent() directly in the megaraid code instead.  The dev
435		is just &pci_dev->dev.

437		James <James.Bottomley@SteelEye.com>
438	
439		3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.
440		4. Hibernation support added
441		5. Performing diskdump while running IO in RHEL 4 was failing. Fixed.

450	
451	i.	Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
452	
453		The driver now waits for 10 seconds to elapse instead of 5 (as in
454		previous release) to resume IO.

462	
463	i.	Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
464	
465		Fix:	The driver is now throttling IO.
466		Checks added in megasas_queue_command to know if FW is able to
467		process commands within timeout period. If number of retries
468		is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
469		resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
470		from the time cmds were last sent to FW.
471	
472	ii.	FW enables WCE bit in Mode Sense cmd for drives that are configured
473		as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
474		Disks are exposed with WCE=1. User is advised to enable Write Back
475		mode only when the controller has battery backup. At this time
476		Synhronize cache is not supported by the FW. Driver will short-cycle
477		the cmd and return success without sending down to FW.

490	
491	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.
492	2. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
493	   (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

501		Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.
502	
503			- Henrik Kretzschmar <henne@nachtwindheim.de>
504	ii.	All compiler warnings removed

506	iv.	Default value of megasas_dbg_lvl set to 0
507	v.	Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
508	vi.	In megasas_teardown_frame_pool(), cmd->frame was passed instead of
509		cmd->sense to pci_pool_free. Fixed. Bug was pointed out by

524	i.	Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
525		New varible added to set dbg level.
526	ii.	Disable interrupt made as fn pointer as they are different for 1068 / 1078
527	iii.	Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
528		3 SGE for 32 bit SGL
529	iv.	Tasklet added for cmd completion
530	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.
531	vi.	megasas_ctrl_prop structure updated (based on FW struct)
532	vii.	Added print : FW now in Ready State during initialization

549	
550			Interrupt is enabled after required initialization is over.
551			This is done to ensure that driver is ready to handle interrupts when
552			it is generated by the controller.

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.
