1973 Older Version   : 00.00.04.17.1-rc1
198
1991.	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	affect the OS behavior.
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
2282.	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.
2323.	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.
2354.	Add the input parameter max_sectors to 1MB support to our GEN2 controller.
236	customer can use the input parameter max_sectors to add 1MB support to GEN2
237	controller.

250	keep the logic drive list internal after driver load.

253	PD delete/ADD, LD add/delete from FW.

383	interrupts are delayed. At the end of initiating IOs, the
384	driver schedules for cmd completion if there are pending cmds

3971. 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

4341.  When MegaSAS driver receives reset call from OS, driver waits in reset
435routine for max 3 minutes for all pending command completion. Now driver will
436call completion routine every 5 seconds from the reset routine instead of
437waiting 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

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.

478i.	Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors

480	The driver now waits for 10 seconds to elapse instead of 5 (as in
481	previous release) to resume IO.

490i.	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
499ii.	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.

5181. 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.
5192. 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 do not accept any processing of pending cmds/accept any cmd from OS

531ii.	All compiler warnings removed

535vi.	In megasas_teardown_frame_pool(), cmd->frame was passed instead of

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

579		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.
