1603 Older Version   : 00.00.04.17.1-rc1
161
1621.	Add the Online Controller Reset (OCR) to the Driver.
163	OCR is the new feature for megaraid_sas driver which
164	will allow the fw to do the chip reset which will not
165	affact the OS behavious.
166
167	To add the OCR support, driver need to do:
168		a). reset the controller chips -- Xscale and Gen2 which
169		will change the function calls and add the reset function
170		related to this two chips.
171
172		b). during the reset, driver will store the pending cmds
173		which not returned by FW to driver's pending queue.  Driver
174		will re-issue those pending cmds again to FW after the OCR
175		finished.
176
177		c). In driver's timeout routine, driver will report to
178		OS as reset. Also driver's queue routine will block the
179		cmds until the OCR finished.
180
181		d). in Driver's ISR routine, if driver get the FW state as
182		state change, FW in Failure status and FW support online controller
183		reset (OCR), driver will start to do the controller reset.
184
185		e). In driver's IOCTL routine, the application cmds will wait for the
186		OCR to finish, then issue the cmds to FW.
187
188		f). Before driver kill adapter, driver will do last chance of
189		OCR to see if driver can bring back the FW.
190
1912.	Add the support update flag to the driver to tell LSI megaraid_sas
192	application which driver will support the device update.  So application
193	will not need to do the device update after application add/del the device
194	from the system.
1953.	In driver's timeout routine, driver will do three time reset if fw is in
196	failed state.  Driver will kill adapter if can't bring back FW after the
197	this three times reset.
1984.	Add the input parameter max_sectors to 1MB support to our GEN2 controller.
199	customer can use the input paramenter max_sectors to add 1MB support to GEN2
200	controller.

213	keep the logic drive list internal after driver load.

3601. Setting the max_sectors_per_req based on max SGL supported by the
361	FW. Prior versions calculated this value from controller info
362	(max_sectors_1, max_sectors_2). For certain controllers/FW,
363	this was resulting in a value greater than max SGL supported
364	by the FW. Issue was first reported by users running LUKS+XFS
365	with megaraid_sas.  Thanks to RB for providing the logs and
366	duplication steps that helped to get to the root cause of the
367	issue.  2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
368	10. FW may take a max of 60 seconds to respond to the INIT
369	cmd.

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

429	3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.
430	4. Hibernation support added
431	5. Performing diskdump while running IO in RHEL 4 was failing. Fixed.

441i.	Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
442
443	The driver now waits for 10 seconds to elapse instead of 5 (as in
444	previous release) to resume IO.

452
453i.	Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
454
455	Fix:	The driver is now throttling IO.
456	Checks added in megasas_queue_command to know if FW is able to
457	process commands within timeout period. If number of retries
458	is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
459	resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
460	from the time cmds were last sent to FW.
461
462ii.	FW enables WCE bit in Mode Sense cmd for drives that are configured
463	as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
464	Disks are exposed with WCE=1. User is advised to enable Write Back
465	mode only when the controller has battery backup. At this time
466	Synhronize cache is not supported by the FW. Driver will short-cycle
467	the cmd and return success without sending down to FW.

4811. 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.
4822. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
483   (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

492

494ii.	All compiler warnings removed
495iii.	megasas_ctrl_info struct reverted to 3.02 release
496iv.	Default value of megasas_dbg_lvl set to 0
497v.	Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
498vi.	In megasas_teardown_frame_pool(), cmd->frame was passed instead of
499	cmd->sense to pci_pool_free. Fixed. Bug was pointed out by

514i.	Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
515	New varible added to set dbg level.
516ii.	Disable interrupt made as fn pointer as they are different for 1068 / 1078
517iii.	Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
518	3 SGE for 32 bit SGL
519iv.	Tasklet added for cmd completion
520v.	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.
521vi.	megasas_ctrl_prop structure updated (based on FW struct)
522vii.	Added print : FW now in Ready State during initialization

539
540		Interrupt is enabled after required initialization is over.
541		This is done to ensure that driver is ready to handle interrupts when
542		it is generated by the controller.

585i.	New template defined to represent each family of controllers (identified by processor used).
586	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.
