169 2 Current Version : 00.00.04.31-rc1
170 3 Older Version : 00.00.04.17.1-rc1
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.
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.
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.
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.
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.
195 e). In driver's IOCTL routine, the application cmds will wait for the
196 OCR to finish, then issue the cmds to FW.
198 f). Before driver kill adapter, driver will do last chance of
199 OCR to see if driver can bring back the FW.
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.

322 Sense buffer ptr data type in the ioctl path is reverted back
323 to u32 * as in previous versions of driver.
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.
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.

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.

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.

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.

463 i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
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.
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.

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

496 2 Current Version : 00.00.03.05
497 3 Older Version : 00.00.03.04
499 i. PCI_DEVICE macro used
501 Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.
503 - Henrik Kretzschmar <henne@nachtwindheim.de>
504 ii. All compiler warnings removed
505 iii. megasas_ctrl_info struct reverted to 3.02 release
506 iv. Default value of megasas_dbg_lvl set to 0
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
510 Eric Sesterhenn

514 3 Older Version : 00.00.03.03
516 i. Added Reboot notify
517 ii. Reduced by 1 max cmds sent to FW from Driver to make the reply_q_sz same
518 as Max Cmds FW can support

521 2 Current Version : 00.00.03.03
522 3 Older Version : 00.00.03.02
524 i. Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
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

541 2 Current Version : 00.00.03.01
542 3 Older Version : 00.00.02.04
544 i. Added support for ZCR controller.
546 New device id 0x413 added.
548 ii. Bug fix : Disable controller interrupt before firing INIT cmd to FW.
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.

560 i. Remove superflous instance_lock
562 gets rid of the otherwise superflous instance_lock and avoids an unsave
563 unsynchronized access in the error handler.

570 3 Older Version : 00.00.02.04
572 i. Support for 1078 type (ppc IOP) controller, device id : 0x60 added.
573 During initialization, depending on the device id, the template members
574 are initialized with function pointers specific to the ppc or
575 xscale controllers.

583 i. Register 16 byte CDB capability with scsi midlayer
585 "This patch properly registers the 16 byte command length capability of the
586 megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas
587 hardware supports 16 byte CDB's."

595 i. New template defined to represent each family of controllers (identified by processor used).
596 The template will have defintions that will be initialised to appropritae values for a specific family of controllers. The template definition has four function pointers. During driver initialisation the function pointers will be set based on the controller family type. This change is done to support new controllers that has different processors and thus different register set.

604 i. Code reorganized to remove code duplication in megasas_build_cmd.
606 "There's a lot of duplicate code megasas_build_cmd. Move that out of the different codepathes and merge the reminder of megasas_build_cmd into megasas_queue_command"
608 - Christoph Hellwig <hch@lst.de>
610 ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems.
612 "MEGASAS_IOC_FIRMWARE can't be redefined if CONFIG_COMPAT is set, we need to define a MEGASAS_IOC_FIRMWARE32 define so native binaries continue to work"
