May 03, 2010 09:12:45 PST 2009 - + (emaild-id:megaraidlinux@lsi.com) + Bo Yang + +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. + 1 Release Date : Thur.
