* [SCSI] megaraid_sas: Add Online Controller Reset to MegaRAID SAS drivebo yang2010-10-07
| | | | | | | | | | | | | | | | | | | | | To add the Online controller reset 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.

When driver receive add or delete AEN from FW, driver will send the DCMD cmd to get the System PD list from FW. Then driver will check if this device already in the OS: If add event and OS don't have the device (but it is in the list), driver add the device to OS, otherwise driver will not add. If remove event, driver will check the list, if is not in the list, but OS have the device, driver will remove the device.

| | | | | | | | | | | | | Added module parameter "poll_mode_io" to support for "polling" (reduced interrupt operation). In this mode, IO completion interrupts are delayed. At the end of initiating IOs, the driver schedules for cmd completion if there are pending cmds. A timer-based interrupt has also been added to prevent IO completion from being delayed indefinitely in the case that no new IOs are initiated.

Prior versions calculated this value from controller info's max_sectors_1, max_sectors_2. For certain controllers/FW, this was resulting in a value greater than max SGL supported by the FW. Now we take the min of max sgl from FW and max_sectors calculation. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 10. FW may take a max of 60 seconds to respond to the INIT cmd.
