182 2 Current Version : 00.00.04.31-rc1
183 3 Older Version : 00.00.04.17.1-rc1
185 1. Add the Online Controller Reset (OCR) to the Driver.
186 OCR is the new feature for megaraid_sas driver which
187 will allow the fw to do the chip reset which will not
188 affact the OS behavious.
190 To add the OCR support, driver need to do:
191 a). reset the controller chips -- Xscale and Gen2 which
192 will change the function calls and add the reset function
193 related to this two chips.
195 b). during the reset, driver will store the pending cmds
196 which not returned by FW to driver's pending queue. Driver
197 will re-issue those pending cmds again to FW after the OCR
198 finished.
200 c). In driver's timeout routine, driver will report to
201 OS as reset. Also driver's queue routine will block the
202 cmds until the OCR finished.
204 d). in Driver's ISR routine, if driver get the FW state as
205 state change, FW in Failure status and FW support online controller
206 reset (OCR), driver will start to do the controller reset.
208 e). In driver's IOCTL routine, the application cmds will wait for the
209 OCR to finish, then issue the cmds to FW.
211 f). Before driver kill adapter, driver will do last chance of
212 OCR to see if driver can bring back the FW.
214 2. Add the support update flag to the driver to tell LSI megaraid_sas
215 application which driver will support the device update. So application
216 will not need to do the device update after application add/del the device
217 from the system.
218 3. In driver's timeout routine, driver will do three time reset if fw is in
219 failed state. Driver will kill adapter if can't bring back FW after the
220 this three times reset.
221 4. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
222 customer can use the input paramenter max_sectors to add 1MB support to GEN2
223 controller.

335 Sense buffer ptr data type in the ioctl path is reverted back
336 to u32 * as in previous versions of driver.
338 2. Fixed the driver frame count.
339 When Driver sent wrong frame count to firmware. As this
340 particular command is sent to drive, FW is seeing continuous
341 chip resets and so the command will timeout.
343 3. Add the new controller(1078DE) support to the driver
344 and Increase the max_wait to 60 from 10 in the controller
345 operational status. With this max_wait increase, driver will
346 make sure the FW will finish the pending cmd for KDUMP case.

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

385 (max_sectors_1, max_sectors_2). For certain controllers/FW,
386 this was resulting in a value greater than max SGL supported
387 by the FW. Issue was first reported by users running LUKS+XFS
388 with megaraid_sas. Thanks to RB for providing the logs and
389 duplication steps that helped to get to the root cause of the
390 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from

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

479 Checks added in megasas_queue_command to know if FW is able to
480 process commands within timeout period. If number of retries
481 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
482 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
483 from the time cmds were last sent to FW.
485 ii. FW enables WCE bit in Mode Sense cmd for drives that are configured
486 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
487 Disks are exposed with WCE=1. User is advised to enable Write Back
488 mode only when the controller has battery backup. At this time
489 Synhronize cache is not supported by the FW. Driver will short-cycle
490 the cmd and return success without sending down to FW.

504 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.
505 2. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
506 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

512 i. PCI_DEVICE macro used
514 Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.

517 ii. All compiler warnings removed
518 iii. megasas_ctrl_info struct reverted to 3.02 release
519 iv. Default value of megasas_dbg_lvl set to 0
520 v. Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
521 vi. In megasas_teardown_frame_pool(), cmd->frame was passed instead of
522 cmd->sense to pci_pool_free. Fixed. Bug was pointed out by

529 i. Added Reboot notify
530 ii. Reduced by 1 max cmds sent to FW from Driver to make the reply_q_sz same
531 as Max Cmds FW can support

537 i. Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
538 New varible added to set dbg level.
539 ii. Disable interrupt made as fn pointer as they are different for 1068 / 1078
540 iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
541 3 SGE for 32 bit SGL
542 iv. Tasklet added for cmd completion
543 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.
544 vi. megasas_ctrl_prop structure updated (based on FW struct)
545 vii. Added print : FW now in Ready State during initialization

557 i. Added support for ZCR controller.
559 New device id 0x413 added.
561 ii. Bug fix : Disable controller interrupt before firing INIT cmd to FW.
563 Interrupt is enabled after required initialization is over.
564 This is done to ensure that driver is ready to handle interrupts when
565 it is generated by the controller.

586 During initialization, depending on the device id, the template members
587 are initialized with function pointers specific to the ppc or
588 xscale controllers.

596 i. Register 16 byte CDB capability with scsi midlayer
598 "This patch properly registers the 16 byte command length capability of the
599 megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas
600 hardware supports 16 byte CDB's."

608 i. New template defined to represent each family of controllers (identified by processor used).
609 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.

617 i. Code reorganized to remove code duplication in megasas_build_cmd.
619 "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"

623 ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems.
625 "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"
