197 3 Older Version : 00.00.04.17.1-rc1
198
199 1. Add the Online Controller Reset (OCR) to the Driver.
200 OCR is the new feature for megaraid_sas driver which
201 will allow the fw to do the chip reset which will not
202 affect the OS behavior.
203
204 To add the OCR support, driver need to do:
205 a). reset the controller chips -- Xscale and Gen2 which
206 will change the function calls and add the reset function
207 related to this two chips.
208
209 b). during the reset, driver will store the pending cmds
210 which not returned by FW to driver's pending queue. Driver
211 will re-issue those pending cmds again to FW after the OCR
212 finished.
213
214 c). In driver's timeout routine, driver will report to
215 OS as reset. Also driver's queue routine will block the
216 cmds until the OCR finished.
217
218 d). in Driver's ISR routine, if driver get the FW state as
219 state change, FW in Failure status and FW support online controller
220 reset (OCR), driver will start to do the controller reset.
221
222 e). In driver's IOCTL routine, the application cmds will wait for the
223 OCR to finish, then issue the cmds to FW.
224
225 f). Before driver kill adapter, driver will do last chance of
226 OCR to see if driver can bring back the FW.
227
228 2. Add the support update flag to the driver to tell LSI megaraid_sas
229 application which driver will support the device update. So application
230 will not need to do the device update after application add/del the device
231 from the system.
232 3. In driver's timeout routine, driver will do three time reset if fw is in
233 failed state. Driver will kill adapter if can't bring back FW after the
234 this three times reset.
235 4. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
236 customer can use the input parameter max_sectors to add 1MB support to GEN2
237 controller.

249 2. Add the logic drive list to the driver. Driver will
250 keep the logic drive list internal after driver load.

253 PD delete/ADD, LD add/delete from FW.

348 1. Rollback the sense info implementation
349 Sense buffer ptr data type in the ioctl path is reverted back
350 to u32 * as in previous versions of driver.
351
352 2. Fixed the driver frame count.
353 When Driver sent wrong frame count to firmware. As this
354 particular command is sent to drive, FW is seeing continuous
355 chip resets and so the command will timeout.
356
357 3. Add the new controller(1078DE) support to the driver
358 and Increase the max_wait to 60 from 10 in the controller
359 operational status. With this max_wait increase, driver will
360 make sure the FW will finish the pending cmd for KDUMP case.

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

397 1. Setting the max_sectors_per_req based on max SGL supported by the
398 FW. Prior versions calculated this value from controller info
399 (max_sectors_1, max_sectors_2). For certain controllers/FW,
400 this was resulting in a value greater than max SGL supported
401 by the FW. Issue was first reported by users running LUKS+XFS
402 with megaraid_sas. Thanks to RB for providing the logs and
403 duplication steps that helped to get to the root cause of the
404 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
405 10. FW may take a max of 60 seconds to respond to the INIT
406 cmd.

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

466 3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.
467 4. Hibernation support added
468 5. Performing diskdump while running IO in RHEL 4 was failing. Fixed.

478 i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
479
480 The driver now waits for 10 seconds to elapse instead of 5 (as in
481 previous release) to resume IO.

489
490 i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
491
492 Fix: The driver is now throttling IO.
493 Checks added in megasas_queue_command to know if FW is able to
494 process commands within timeout period. If number of retries
495 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
496 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
497 from the time cmds were last sent to FW.
498
499 ii. FW enables WCE bit in Mode Sense cmd for drives that are configured
500 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
501 Disks are exposed with WCE=1. User is advised to enable Write Back
502 mode only when the controller has battery backup. At this time
503 Synhronize cache is not supported by the FW. Driver will short-cycle
504 the cmd and return success without sending down to FW.

518 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.
519 2. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
520 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

527
528 Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.
529
530 - Henrik Kretzschmar <henne@nachtwindheim.de>
531 ii. All compiler warnings removed
532 iii. megasas_ctrl_info struct reverted to 3.02 release
533 iv. Default value of megasas_dbg_lvl set to 0
534 v. Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
535 vi. In megasas_teardown_frame_pool(), cmd->frame was passed instead of
536 cmd->sense to pci_pool_free. Fixed. Bug was pointed out by

551 i. Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
552 New variable added to set dbg level.
553 ii. Disable interrupt made as fn pointer as they are different for 1068 / 1078
554 iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
555 3 SGE for 32 bit SGL
556 iv. Tasklet added for cmd completion
557 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.
558 vi. megasas_ctrl_prop structure updated (based on FW struct)
559 vii. Added print : FW now in Ready State during initialization

572
573 New device id 0x413 added.
574
575 ii. Bug fix : Disable controller interrupt before firing INIT cmd to FW.
576
577 Interrupt is enabled after required initialization is over.
578 This is done to ensure that driver is ready to handle interrupts when
579 it is generated by the controller.

601 are initialized with function pointers specific to the ppc or
602 xscale controllers.

622 i. New template defined to represent each family of controllers (identified by processor used).
623 The template will have definitions that will be initialised to appropriate 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.
