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.
