Add the Online Controller Reset (OCR) to the Driver. 163 OCR is the new feature for megaraid_sas driver which 164 will allow the fw to do the chip reset which will not 165 affact the OS behavious. 166 167 To add the OCR support, driver need to do: 168 a). reset the controller chips -- Xscale and Gen2 which 169 will change the function calls and add the reset function 170 related to this two chips. 171 172 b). during the reset, driver will store the pending cmds 173 which not returned by FW to driver's pending queue. Driver 174 will re-issue those pending cmds again to FW after the OCR 175 finished. 176 177 c). In driver's timeout routine, driver will report to 178 OS as reset. Also driver's queue routine will block the 179 cmds until the OCR finished. 180 181 d). in Driver's ISR routine, if driver get the FW state as 182 state change, FW in Failure status and FW support online controller 183 reset (OCR), driver will start to do the controller reset. 184 185 e). In driver's IOCTL routine, the application cmds will wait for the 186 OCR to finish, then issue the cmds to FW. 187 188 f). Before driver kill adapter, driver will do last chance of 189 OCR to see if driver can bring back the FW. 190 1912. Add the support update flag to the driver to tell LSI megaraid_sas 192 application which driver will support the device update. So application 193 will not need to do the device update after application add/del the device 194 from the system. 1953. In driver's timeout routine, driver will do three time reset if fw is in 196 failed state. Driver will kill adapter if can't bring back FW after the 197 this three times reset. 1984. Add the input parameter max_sectors to 1MB support to our GEN2 controller. 199 customer can use the input paramenter max_sectors to add 1MB support to GEN2 200 controller. 201 2021 Release Date : Thur.

Rollback the sense info implementation 312 Sense buffer ptr data type in the ioctl path is reverted back 313 to u32 * as in previous versions of driver. 314 3152. Fixed the driver frame count. 316 When Driver sent wrong frame count to firmware. As this 317 particular command is sent to drive, FW is seeing continuous 318 chip resets and so the command will timeout. 319 3203. Add the new controller(1078DE) support to the driver 321 and Increase the max_wait to 60 from 10 in the controller 322 operational status. With this max_wait increase, driver will 323 make sure the FW will finish the pending cmd for KDUMP case. 324 3251 Release Date : Thur.

Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 10. FW may take 334 a max of 60 seconds to respond to the INIT cmd. 335 3361 Release Date : Fri. Sep. 07 16:30:43 PST 2007 - 337 (emaild-id:megaraidlinux@lsi.com) 338 Sumant Patro 339 Bo Yang 340 3412 Current Version : 00.00.03.15 3423 Older Version : 00.00.03.14 343 3441. Added module parameter "poll_mode_io" to support for "polling" 345 (reduced interrupt operation). In this mode, IO completion 346 interrupts are delayed. At the end of initiating IOs, the 347 driver schedules for cmd completion if there are pending cmds 348 to be completed. A timer-based interrupt has also been added 349 to prevent IO completion processing from being delayed 350 indefinitely in the case that no new IOs are initiated. 351 3521 Release Date : Fri.

Setting the max_sectors_per_req based on max SGL supported by the 361 FW. Prior versions calculated this value from controller info 362 (max_sectors_1, max_sectors_2). For certain controllers/FW, 363 this was resulting in a value greater than max SGL supported 364 by the FW. Issue was first reported by users running LUKS+XFS 365 with megaraid_sas. Thanks to RB for providing the logs and 366 duplication steps that helped to get to the root cause of the 367 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 368 10. FW may take a max of 60 seconds to respond to the INIT 369 cmd. 370 3711 Release Date : Fri.

Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors 454 455 Fix: The driver is now throttling IO. 456 Checks added in megasas_queue_command to know if FW is able to 457 process commands within timeout period. If number of retries 458 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is 459 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed 460 from the time cmds were last sent to FW. 461 462ii. FW enables WCE bit in Mode Sense cmd for drives that are configured 463 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical 464 Disks are exposed with WCE=1. User is advised to enable Write Back 465 mode only when the controller has battery backup. At this time 466 Synhronize cache is not supported by the FW. Driver will short-cycle 467 the cmd and return success without sending down to FW. 468 4691 Release Date : Sun Jan. 14 11:21:32 PDT 2007 - 470 Sumant Patro <Sumant.Patro@lsil.com>/Bo Yang 4712 Current Version : 00.00.03.07 4723 Older Version : 00.00.03.06 473 474i. bios_param entry added in scsi_host_template that returns disk geometry 475 information. 476 4771 Release Date : Fri Oct 20 11:21:32 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com>/Bo Yang 4782 Current Version : 00.00.03.06 4793 Older Version : 00.00.03.05 480 4811. 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. 4822. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead 483 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS 484 4851 Release Date : Mon Oct 02 11:21:32 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com> 4862 Current Version : 00.00.03.05 4873 Older Version : 00.00.03.04 488 489i.

Bug was pointed out by 500 Eric Sesterhenn 501 5021 Release Date : Wed Sep 13 14:22:51 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5032 Current Version : 00.00.03.04 5043 Older Version : 00.00.03.03 505 506i. Added Reboot notify 507ii. Reduced by 1 max cmds sent to FW from Driver to make the reply_q_sz same 508 as Max Cmds FW can support 509 5101 Release Date : Tue Aug 22 16:33:14 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5112 Current Version : 00.00.03.03 5123 Older Version : 00.00.03.02 513 514i. Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead. 515 New varible added to set dbg level. 516ii. Disable interrupt made as fn pointer as they are different for 1068 / 1078 517iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and 518 3 SGE for 32 bit SGL 519iv. Tasklet added for cmd completion 520v. 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. 521vi. megasas_ctrl_prop structure updated (based on FW struct) 522vii. Added print : FW now in Ready State during initialization 523 5241 Release Date : Sun Aug 06 22:49:52 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5252 Current Version : 00.00.03.02 5263 Older Version : 00.00.03.01 527 528i.

Added support for ZCR controller. 535 536 New device id 0x413 added. 537 538ii. Bug fix : Disable controller interrupt before firing INIT cmd to FW. 539 540 Interrupt is enabled after required initialization is over. 541 This is done to ensure that driver is ready to handle interrupts when 542 it is generated by the controller. 543 544 -Sumant Patro <Sumant.Patro@lsil.com> 545 5461 Release Date : Wed Feb 03 14:31:44 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5472 Current Version : 00.00.02.04 5483 Older Version : 00.00.02.04 549 550i. Remove superflous instance_lock 551 552 gets rid of the otherwise superflous instance_lock and avoids an unsave 553 unsynchronized access in the error handler. 554 555 - Christoph Hellwig <hch@lst.de> 556 557 5581 Release Date : Wed Feb 03 14:31:44 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5592 Current Version : 00.00.02.04 5603 Older Version : 00.00.02.04 561 562i. Support for 1078 type (ppc IOP) controller, device id : 0x60 added. 563 During initialization, depending on the device id, the template members 564 are initialized with function pointers specific to the ppc or 565 xscale controllers. 566 567 -Sumant Patro <Sumant.Patro@lsil.com> 568 5691 Release Date : Fri Feb 03 14:16:25 PST 2006 - Sumant Patro 570 <Sumant.Patro@lsil.com> 5712 Current Version : 00.00.02.04 5723 Older Version : 00.00.02.02 573i. Register 16 byte CDB capability with scsi midlayer 574 575 "This patch properly registers the 16 byte command length capability of the 576 megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas 577 hardware supports 16 byte CDB's." 578 579 -Joshua Giles <joshua_giles@dell.com> 580 5811 Release Date : Mon Jan 23 14:09:01 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5822 Current Version : 00.00.02.02 5833 Older Version : 00.00.02.01 584 585i. New template defined to represent each family of controllers (identified by processor used). 586 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. 587 588 -Sumant Patro <Sumant.Patro@lsil.com> 589 5901 Release Date : Mon Dec 19 14:36:26 PST 2005 - Sumant Patro <Sumant.Patro@lsil.com> 5912 Current Version : 00.00.02.00-rc4 5923 Older Version : 00.00.02.01 593 594i. Code reorganized to remove code duplication in megasas_build_cmd. 595 596 "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" 597 598 - Christoph Hellwig <hch@lst.de> 599 600ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems. 601 602 "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" 603 604 - Christoph Hellwig <hch@lst.de> 605
