128 2 Current Version : 00.00.04.31-rc1
129 3 Older Version : 00.00.04.17.1-rc1
131 1. Add the Online Controller Reset (OCR) to the Driver.
132 OCR is the new feature for megaraid_sas driver which
133 will allow the fw to do the chip reset which will not
134 affact the OS behavious.
136 To add the OCR support, driver need to do:
137 a). reset the controller chips -- Xscale and Gen2 which
138 will change the function calls and add the reset function
139 related to this two chips.
141 b). during the reset, driver will store the pending cmds
142 which not returned by FW to driver's pending queue. Driver
143 will re-issue those pending cmds again to FW after the OCR
144 finished.
146 c). In driver's timeout routine, driver will report to
147 OS as reset. Also driver's queue routine will block the
148 cmds until the OCR finished.
150 d). in Driver's ISR routine, if driver get the FW state as
151 state change, FW in Failure status and FW support online controller
152 reset (OCR), driver will start to do the controller reset.
154 e). In driver's IOCTL routine, the application cmds will wait for the
155 OCR to finish, then issue the cmds to FW.
157 f). Before driver kill adapter, driver will do last chance of
158 OCR to see if driver can bring back the FW.
160 2. Add the support update flag to the driver to tell LSI megaraid_sas
161 application which driver will support the device update. So application
162 will not need to do the device update after application add/del the device
163 from the system.
164 3. In driver's timeout routine, driver will do three time reset if fw is in
165 failed state. Driver will kill adapter if can't bring back FW after the
166 this three times reset.
167 4. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
168 customer can use the input paramenter max_sectors to add 1MB support to GEN2
169 controller.

182 keep the logic drive list internal after driver load.

281 Sense buffer ptr data type in the ioctl path is reverted back
282 to u32 * as in previous versions of driver.
284 2. Fixed the driver frame count.
285 When Driver sent wrong frame count to firmware. As this
286 particular command is sent to drive, FW is seeing continuous
287 chip resets and so the command will timeout.
289 3. Add the new controller(1078DE) support to the driver
290 and Increase the max_wait to 60 from 10 in the controller
291 operational status. With this max_wait increase, driver will
292 make sure the FW will finish the pending cmd for KDUMP case.

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

329 1. Setting the max_sectors_per_req based on max SGL supported by the
330 FW. Prior versions calculated this value from controller info
331 (max_sectors_1, max_sectors_2). For certain controllers/FW,
332 this was resulting in a value greater than max SGL supported
333 by the FW. Issue was first reported by users running LUKS+XFS
334 with megaraid_sas. Thanks to RB for providing the logs and
335 duplication steps that helped to get to the root cause of the
336 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
337 10. FW may take a max of 60 seconds to respond to the INIT
338 cmd.

392 It does, but the DMA API was expanded to cope with this exact case, so
393 use dma_alloc_coherent() directly in the megaraid code instead. The dev
394 is just &pci_dev->dev.
396 James <James.Bottomley@SteelEye.com>
398 3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.

422 i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
424 Fix: The driver is now throttling IO.
425 Checks added in megasas_queue_command to know if FW is able to
426 process commands within timeout period. If number of retries
427 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
428 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
429 from the time cmds were last sent to FW.
431 ii. FW enables WCE bit in Mode Sense cmd for drives that are configured
432 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
433 Disks are exposed with WCE=1. User is advised to enable Write Back
434 mode only when the controller has battery backup. At this time
435 Synhronize cache is not supported by the FW. Driver will short-cycle
436 the cmd and return success without sending down to FW.

452 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

480 2 Current Version : 00.00.03.03
481 3 Older Version : 00.00.03.02
483 i. Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
484 New varible added to set dbg level.
485 ii. Disable interrupt made as fn pointer as they are different for 1068 / 1078
486 iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
487 3 SGE for 32 bit SGL
488 iv. Tasklet added for cmd completion
489 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.
490 vi. megasas_ctrl_prop structure updated (based on FW struct)
491 vii. Added print : FW now in Ready State during initialization

494 2 Current Version : 00.00.03.02
495 3 Older Version : 00.00.03.01
497 i. Added FW tranistion state for Hotplug scenario
499 1 Release Date : Sun May 14 22:49:52 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com>
500 2 Current Version : 00.00.03.01
501 3 Older Version : 00.00.02.04
503 i. Added support for ZCR controller.
505 New device id 0x413 added.
507 ii. Bug fix : Disable controller interrupt before firing INIT cmd to FW.
509 Interrupt is enabled after required initialization is over.
510 This is done to ensure that driver is ready to handle interrupts when
511 it is generated by the controller.

519 i. Remove superflous instance_lock
521 gets rid of the otherwise superflous instance_lock and avoids an unsave
522 unsynchronized access in the error handler.

529 3 Older Version : 00.00.02.04
531 i. Support for 1078 type (ppc IOP) controller, device id : 0x60 added.
532 During initialization, depending on the device id, the template members
533 are initialized with function pointers specific to the ppc or
534 xscale controllers.

542 i. Register 16 byte CDB capability with scsi midlayer
544 "This patch properly registers the 16 byte command length capability of the
545 megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas
546 hardware supports 16 byte CDB's."

552 3 Older Version : 00.00.02.01
554 i. New template defined to represent each family of controllers (identified by processor used).
555 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.

560 2 Current Version : 00.00.02.00-rc4
561 3 Older Version : 00.00.02.01
563 i. Code reorganized to remove code duplication in megasas_build_cmd.
565 "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"
567 - Christoph Hellwig <hch@lst.de>
569 ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems.
571 "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"
