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 hbhavious. + + To add the OCR support, driver need to do: + a). reset the controller chip -- Xscale and Gen2. + + b). during the reset, driver will store the pending + cmds to pending queue. + + c). Also in driver's timeout routine, driver will + report to OS as reset. + + d). in Driver's ISR routine, if driver get the FW + state as state change and FW in Failure status, + driver will start to do the controller reset. + + e). If driver goes to timeout, but driver is in + operational status, driver will check if fw in failed + status, if yes, driver will do OCR to FW upto three times. + + f). Before driver kill adapter, driver will do last chance of + OCR to see if driver can bring back the FW. + +2. Add the CTIO support to the driver. +3. 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. + +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. + 1 Release Date : Thur.
