|
|
+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.
