Add the Online Controller Reset (OCR) to the Driver. 141 OCR is the new feature for megaraid_sas driver which 142 will allow the fw to do the chip reset which will not 143 affact the OS behavious. 144 145 To add the OCR support, driver need to do: 146 a). reset the controller chips -- Xscale and Gen2 which 147 will change the function calls and add the reset function 148 related to this two chips. 149 150 b). during the reset, driver will store the pending cmds 151 which not returned by FW to driver's pending queue. Driver 152 will re-issue those pending cmds again to FW after the OCR 153 finished. 154 155 c). In driver's timeout routine, driver will report to 156 OS as reset. Also driver's queue routine will block the 157 cmds until the OCR finished. 158 159 d). in Driver's ISR routine, if driver get the FW state as 160 state change, FW in Failure status and FW support online controller 161 reset (OCR), driver will start to do the controller reset. 162 163 e). In driver's IOCTL routine, the application cmds will wait for the 164 OCR to finish, then issue the cmds to FW. 165 166 f). Before driver kill adapter, driver will do last chance of 167 OCR to see if driver can bring back the FW. 168 1692. Add the support update flag to the driver to tell LSI megaraid_sas 170 application which driver will support the device update. So application 171 will not need to do the device update after application add/del the device 172 from the system. 1733. In driver's timeout routine, driver will do three time reset if fw is in 174 failed state. Driver will kill adapter if can't bring back FW after the 175 this three times reset. 1764. Add the input parameter max_sectors to 1MB support to our GEN2 controller. 177 customer can use the input paramenter max_sectors to add 1MB support to GEN2 178 controller. 179 1801 Release Date : Thur.

Rollback the sense info implementation 290 Sense buffer ptr data type in the ioctl path is reverted back 291 to u32 * as in previous versions of driver. 292 2932. Fixed the driver frame count. 294 When Driver sent wrong frame count to firmware. As this 295 particular command is sent to drive, FW is seeing continuous 296 chip resets and so the command will timeout. 297 2983. Add the new controller(1078DE) support to the driver 299 and Increase the max_wait to 60 from 10 in the controller 300 operational status. With this max_wait increase, driver will 301 make sure the FW will finish the pending cmd for KDUMP case. 302 3031 Release Date : Thur.

Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 10. FW may take 312 a max of 60 seconds to respond to the INIT cmd. 313 3141 Release Date : Fri. Sep. 07 16:30:43 PST 2007 - 315 (emaild-id:megaraidlinux@lsi.com) 316 Sumant Patro 317 Bo Yang 318 3192 Current Version : 00.00.03.15 3203 Older Version : 00.00.03.14 321 3221. Added module parameter "poll_mode_io" to support for "polling" 323 (reduced interrupt operation). In this mode, IO completion 324 interrupts are delayed. At the end of initiating IOs, the 325 driver schedules for cmd completion if there are pending cmds 326 to be completed. A timer-based interrupt has also been added 327 to prevent IO completion processing from being delayed 328 indefinitely in the case that no new IOs are initiated. 329 3301 Release Date : Fri. Sep. 07 16:30:43 PST 2007 - 331 (emaild-id:megaraidlinux@lsi.com) 332 Sumant Patro 333 Bo Yang 334 3352 Current Version : 00.00.03.14 3363 Older Version : 00.00.03.13 337 3381. Setting the max_sectors_per_req based on max SGL supported by the 339 FW. Prior versions calculated this value from controller info 340 (max_sectors_1, max_sectors_2). For certain controllers/FW, 341 this was resulting in a value greater than max SGL supported 342 by the FW. Issue was first reported by users running LUKS+XFS 343 with megaraid_sas. Thanks to RB for providing the logs and 344 duplication steps that helped to get to the root cause of the 345 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 346 10. FW may take a max of 60 seconds to respond to the INIT 347 cmd. 348 3491 Release Date : Fri.

When MegaSAS driver receives reset call from OS, driver waits in reset 376routine for max 3 minutes for all pending command completion. Now driver will 377call completion routine every 5 seconds from the reset routine instead of 378waiting for depending on cmd completion from isr path. 379 3801 Release Date : Mon Apr. 30 10:25:52 PST 2007 - 381 (emaild-id:megaraidlinux@lsi.com) 382 Sumant Patro 383 Bo Yang 384 3852 Current Version : 00.00.03.11 3863 Older Version : 00.00.03.09 387 388 1.

Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors 432 433 Fix: The driver is now throttling IO. 434 Checks added in megasas_queue_command to know if FW is able to 435 process commands within timeout period. If number of retries 436 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is 437 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed 438 from the time cmds were last sent to FW. 439 440ii. FW enables WCE bit in Mode Sense cmd for drives that are configured 441 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical 442 Disks are exposed with WCE=1. User is advised to enable Write Back 443 mode only when the controller has battery backup. At this time 444 Synhronize cache is not supported by the FW. Driver will short-cycle 445 the cmd and return success without sending down to FW. 446 4471 Release Date : Sun Jan. 14 11:21:32 PDT 2007 - 448 Sumant Patro <Sumant.Patro@lsil.com>/Bo Yang 4492 Current Version : 00.00.03.07 4503 Older Version : 00.00.03.06 451 452i. bios_param entry added in scsi_host_template that returns disk geometry 453 information. 454 4551 Release Date : Fri Oct 20 11:21:32 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com>/Bo Yang 4562 Current Version : 00.00.03.06 4573 Older Version : 00.00.03.05 458 4591. 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. 4602. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead 461 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS 462 4631 Release Date : Mon Oct 02 11:21:32 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com> 4642 Current Version : 00.00.03.05 4653 Older Version : 00.00.03.04 466 467i.

This is used to do soft reset. 499vi. megasas_ctrl_prop structure updated (based on FW struct) 500vii. Added print : FW now in Ready State during initialization 501 5021 Release Date : Sun Aug 06 22:49:52 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5032 Current Version : 00.00.03.02 5043 Older Version : 00.00.03.01 505 506i. Added FW tranistion state for Hotplug scenario 507 5081 Release Date : Sun May 14 22:49:52 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5092 Current Version : 00.00.03.01 5103 Older Version : 00.00.02.04 511 512i. Added support for ZCR controller. 513 514 New device id 0x413 added. 515 516ii. Bug fix : Disable controller interrupt before firing INIT cmd to FW. 517 518 Interrupt is enabled after required initialization is over. 519 This is done to ensure that driver is ready to handle interrupts when 520 it is generated by the controller. 521 522 -Sumant Patro <Sumant.Patro@lsil.com> 523 5241 Release Date : Wed Feb 03 14:31:44 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5252 Current Version : 00.00.02.04 5263 Older Version : 00.00.02.04 527 528i. Remove superflous instance_lock 529 530 gets rid of the otherwise superflous instance_lock and avoids an unsave 531 unsynchronized access in the error handler. 532 533 - Christoph Hellwig <hch@lst.de> 534 535 5361 Release Date : Wed Feb 03 14:31:44 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5372 Current Version : 00.00.02.04 5383 Older Version : 00.00.02.04 539 540i. Support for 1078 type (ppc IOP) controller, device id : 0x60 added. 541 During initialization, depending on the device id, the template members 542 are initialized with function pointers specific to the ppc or 543 xscale controllers. 544 545 -Sumant Patro <Sumant.Patro@lsil.com> 546 5471 Release Date : Fri Feb 03 14:16:25 PST 2006 - Sumant Patro 548 <Sumant.Patro@lsil.com> 5492 Current Version : 00.00.02.04 5503 Older Version : 00.00.02.02 551i. Register 16 byte CDB capability with scsi midlayer 552 553 "This patch properly registers the 16 byte command length capability of the 554 megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas 555 hardware supports 16 byte CDB's." 556 557 -Joshua Giles <joshua_giles@dell.com> 558 5591 Release Date : Mon Jan 23 14:09:01 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5602 Current Version : 00.00.02.02 5613 Older Version : 00.00.02.01 562 563i. New template defined to represent each family of controllers (identified by processor used). 564 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. 565 566 -Sumant Patro <Sumant.Patro@lsil.com> 567 5681 Release Date : Mon Dec 19 14:36:26 PST 2005 - Sumant Patro <Sumant.Patro@lsil.com> 5692 Current Version : 00.00.02.00-rc4 5703 Older Version : 00.00.02.01 571 572i. Code reorganized to remove code duplication in megasas_build_cmd. 573 574 "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" 575 576 - Christoph Hellwig <hch@lst.de> 577 578ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems. 579 580 "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" 581 582 - Christoph Hellwig <hch@lst.de> 583
