2 Current Version : 00.00.04.31-rc1

3 Older Version   : 00.00.04.17.1-rc1



1.	Add the Online Controller Reset (OCR) to the Driver.

	OCR is the new feature for megaraid_sas driver which

	will allow the fw to do the chip reset which will not

	affact the OS behavious.



	To add the OCR support, driver need to do:

		a). reset the controller chips -- Xscale and Gen2 which

		will change the function calls and add the reset function

		related to this two chips.



		b). during the reset, driver will store the pending cmds

		which not returned by FW to driver's pending queue.  Driver

		will re-issue those pending cmds again to FW after the OCR

		finished.



		c). In driver's timeout routine, driver will report to

		OS as reset. Also driver's queue routine will block the

		cmds until the OCR finished.



		d). in Driver's ISR routine, if driver get the FW state as

		state change, FW in Failure status and FW support online controller

		reset (OCR), driver will start to do the controller reset.



		e). In driver's IOCTL routine, the application cmds will wait for the

		OCR to finish, then issue the cmds to FW.



		f). Before driver kill adapter, driver will do last chance of

		OCR to see if driver can bring back the FW.



2.	Add the support update flag to the driver to tell LSI megaraid_sas

	application which driver will support the device update.  So application

	will not need to do the device update after application add/del the device

	from the system.

3.	In driver's timeout routine, driver will do three time reset if fw is in

	failed state.  Driver will kill adapter if can't bring back FW after the

	this three times reset.

4.	Add the input parameter max_sectors to 1MB support to our GEN2 controller.

	customer can use the input paramenter max_sectors to add 1MB support to GEN2

	controller.
