||||||
|
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.
