Add the Online Controller Reset (OCR) to the Driver.99+ OCR is the new feature for megaraid_sas driver which1010+ will allow the fw to do the chip reset which will not1111+ affact the OS behavious.1212+1313+ To add the OCR support, driver need to do:1414+ a). reset the controller chips -- Xscale and Gen2 which1515+ will change the function calls and add the reset function1616+ related to this two chips.1717+1818+ b). during the reset, driver will store the pending cmds1919+ which not returned by FW to driver's pending queue. Driver2020+ will re-issue those pending cmds again to FW after the OCR2121+ finished.2222+2323+ c). In driver's timeout routine, driver will report to2424+ OS as reset. Also driver's queue routine will block the2525+ cmds until the OCR finished.2626+2727+ d). in Driver's ISR routine, if driver get the FW state as2828+ state change, FW in Failure status and FW support online controller2929+ reset (OCR), driver will start to do the controller reset.3030+3131+ e). In driver's IOCTL routine, the application cmds will wait for the3232+ OCR to finish, then issue the cmds to FW.3333+3434+ f). Before driver kill adapter, driver will do last chance of3535+ OCR to see if driver can bring back the FW.3636+3737+2. Add the support update flag to the driver to tell LSI megaraid_sas3838+ application which driver will support the device update. So application3939+ will not need to do the device update after application add/del the device4040+ from the system.4141+3. In driver's timeout routine, driver will do three time reset if fw is in4242+ failed state. Driver will kill adapter if can't bring back FW after the4343+ this three times reset.4444+4. Add the input parameter max_sectors to 1MB support to our GEN2 controller.4545+ customer can use the input paramenter max_sectors to add 1MB support to GEN24646+ controller.4747+1481 Release Date : Thur.
