 170 3 Older Version   : 00.00.04.17.1-rc1
 171
 172 1.      Add the Online Controller Reset (OCR) to the Driver.
 173         OCR is the new feature for megaraid_sas driver which
 174         will allow the fw to do the chip reset which will not
 175         affact the OS behavious.
 176
 177         To add the OCR support, driver need to do:
 178                 a). reset the controller chips -- Xscale and Gen2 which
 179                 will change the function calls and add the reset function
 180                 related to this two chips.
 181
 182                 b). during the reset, driver will store the pending cmds
 183                 which not returned by FW to driver's pending queue.  Driver
 184                 will re-issue those pending cmds again to FW after the OCR
 185                 finished.
 186
 187                 c). In driver's timeout routine, driver will report to
 188                 OS as reset. Also driver's queue routine will block the
 189                 cmds until the OCR finished.
 190
 191                 d). in Driver's ISR routine, if driver get the FW state as
 192                 state change, FW in Failure status and FW support online controller
 193                 reset (OCR), driver will start to do the controller reset.
 194
 195                 e). In driver's IOCTL routine, the application cmds will wait for the
 196                 OCR to finish, then issue the cmds to FW.
 197
 198                 f). Before driver kill adapter, driver will do last chance of
 199                 OCR to see if driver can bring back the FW.
 200
 201 2.      Add the support update flag to the driver to tell LSI megaraid_sas
 202         application which driver will support the device update.  So application
 203         will not need to do the device update after application add/del the device
 204         from the system.
 205 3.      In driver's timeout routine, driver will do three time reset if fw is in
 206         failed state.  Driver will kill adapter if can't bring back FW after the
 207         this three times reset.
 208 4.      Add the input parameter max_sectors to 1MB support to our GEN2 controller.
 209         customer can use the input paramenter max_sectors to add 1MB support to GEN2
 210         controller.

 220         context value larger than 32bit value issue.
 221
 222 2.      Add the logic drive list to the driver.  Driver will
 223         keep the logic drive list internal after driver load.
 224
 225 3.      driver fixed the device update issue after get the AEN
 226         PD delete/ADD, LD add/delete from FW.

 320
 321 1. Rollback the sense info implementation
 322         Sense buffer ptr data type in the ioctl path is reverted back
 323         to u32 * as in previous versions of driver.
 324
 325 2. Fixed the driver frame count.
 326         When Driver sent wrong frame count to firmware.  As this
 327         particular command is sent to drive, FW is seeing continuous
 328         chip resets and so the command will timeout.
 329
 330 3. Add the new controller(1078DE) support to the driver
 331         and Increase the max_wait to 60 from 10 in the controller
 332         operational status.  With this max_wait increase, driver will
 333         make sure the FW will   finish the pending cmd for KDUMP case.

 353
 354 1. Added module parameter "poll_mode_io" to support for "polling"
 355         (reduced interrupt operation).  In this mode, IO completion
 356         interrupts are delayed. At the end of initiating IOs, the
 357         driver schedules for cmd completion if there are pending cmds
 358         to be completed.  A timer-based interrupt has also been added
 359         to prevent IO completion processing from being delayed
 360         indefinitely in the case that no new IOs are initiated.

 369
 370 1. Setting the max_sectors_per_req based on max SGL supported by the
 371         FW. Prior versions calculated this value from controller info
 372         (max_sectors_1, max_sectors_2). For certain controllers/FW,
 373         this was resulting in a value greater than max SGL supported
 374         by the FW. Issue was first reported by users running LUKS+XFS
 375         with megaraid_sas.  Thanks to RB for providing the logs and
 376         duplication steps that helped to get to the root cause of the
 377         issue.  2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
 378         10. FW may take a max of 60 seconds to respond to the INIT
 379         cmd.

 406
 407 1.  When MegaSAS driver receives reset call from OS, driver waits in reset
 408 routine for max 3 minutes for all pending command completion. Now driver will
 409 call completion routine every 5 seconds from the reset routine instead of
 410 waiting for depending on cmd completion from isr path.

 420         1. Memory Manager for IOCTL removed for 2.6 kernels.
 421            pci_alloc_consistent replaced by dma_alloc_coherent. With this
 422            change there is no need of memory manager in the driver code

 432
 433         It does, but the DMA API was expanded to cope with this exact case, so
 434         use dma_alloc_coherent() directly in the megaraid code instead.  The dev
 435         is just &pci_dev->dev.

 438
 439         3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.
 440         4. Hibernation support added
 441         5. Performing diskdump while running IO in RHEL 4 was failing. Fixed.

 450
 451 i.      Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
 452
 453         The driver now waits for 10 seconds to elapse instead of 5 (as in
 454         previous release) to resume IO.

 462
 463 i.      Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
 464
 465         Fix:    The driver is now throttling IO.
 466         Checks added in megasas_queue_command to know if FW is able to
 467         process commands within timeout period. If number of retries
 468         is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
 469         resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
 470         from the time cmds were last sent to FW.
 471
 472 ii.     FW enables WCE bit in Mode Sense cmd for drives that are configured
 473         as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
 474         Disks are exposed with WCE=1. User is advised to enable Write Back
 475         mode only when the controller has battery backup. At this time
 476         Synhronize cache is not supported by the FW. Driver will short-cycle
 477         the cmd and return success without sending down to FW.

 490
 491 1. Added new memory management module to support the IOCTL memory allocation. For IOCTL we try to allocate from the memory pool created during driver initialization. If mem pool is empty then we allocate at run time.
 492 2. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
 493    (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

 507 v.      Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
 508 vi.     In megasas_teardown_frame_pool(), cmd->frame was passed instead of
 509         cmd->sense to pci_pool_free. Fixed. Bug was pointed out by

 525         New varible added to set dbg level.
 526 ii.     Disable interrupt made as fn pointer as they are different for 1068 / 1078
 527 iii.    Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
 528         3 SGE for 32 bit SGL
 529 iv.     Tasklet added for cmd completion
 530 v.      If FW in operational state before firing INIT, now we send RESET Flag to FW instead of just READY. This is used to do soft reset.
 531 vi.     megasas_ctrl_prop structure updated (based on FW struct)
 532 vii.    Added print : FW now in Ready State during initialization

 545
 546                 New device id 0x413 added.
 547
 548 ii.     Bug fix : Disable controller interrupt before firing INIT cmd to FW.
 549
 550                 Interrupt is enabled after required initialization is over.
 551                 This is done to ensure that driver is ready to handle interrupts when
 552                 it is generated by the controller.
