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. 135 136 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. 140 141 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. 145 146 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. 149 150 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. 153 154 e). In driver's IOCTL routine, the application cmds will wait for the 155 OCR to finish, then issue the cmds to FW. 156 157 f). Before driver kill adapter, driver will do last chance of 158 OCR to see if driver can bring back the FW. 159 1602. 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. 1643. 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. 1674. 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. 170 1711 Release Date : Thur.

Rollback the sense info implementation 281 Sense buffer ptr data type in the ioctl path is reverted back 282 to u32 * as in previous versions of driver. 283 2842. 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. 288 2893. 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. 293 2941 Release Date : Thur.

Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 10. FW may take 303 a max of 60 seconds to respond to the INIT cmd. 304 3051 Release Date : Fri. Sep. 07 16:30:43 PST 2007 - 306 (emaild-id:megaraidlinux@lsi.com) 307 Sumant Patro 308 Bo Yang 309 3102 Current Version : 00.00.03.15 3113 Older Version : 00.00.03.14 312 3131. 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. 320 3211 Release Date : Fri.

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. 339 3401 Release Date : Fri.

When MegaSAS driver receives reset call from OS, driver waits in reset 367routine for max 3 minutes for all pending command completion. Now driver will 368call completion routine every 5 seconds from the reset routine instead of 369waiting for depending on cmd completion from isr path. 370 3711 Release Date : Mon Apr. 30 10:25:52 PST 2007 - 372 (emaild-id:megaraidlinux@lsi.com) 373 Sumant Patro 374 Bo Yang 375 3762 Current Version : 00.00.03.11 3773 Older Version : 00.00.03.09 378 379 1.

Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors 423 424 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. 430 431ii. 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.

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. 4512. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead 452 (hw_crit_error=1).

Added support for ZCR controller. 504 505 New device id 0x413 added. 506 507ii. Bug fix : Disable controller interrupt before firing INIT cmd to FW. 508 509 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. 512 513 -Sumant Patro <Sumant.Patro@lsil.com> 514 5151 Release Date : Wed Feb 03 14:31:44 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5162 Current Version : 00.00.02.04 5173 Older Version : 00.00.02.04 518 519i. Remove superflous instance_lock 520 521 gets rid of the otherwise superflous instance_lock and avoids an unsave 522 unsynchronized access in the error handler. 523 524 - Christoph Hellwig <hch@lst.de> 525 526 5271 Release Date : Wed Feb 03 14:31:44 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5282 Current Version : 00.00.02.04 5293 Older Version : 00.00.02.04 530 531i. 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. 535 536 -Sumant Patro <Sumant.Patro@lsil.com> 537 5381 Release Date : Fri Feb 03 14:16:25 PST 2006 - Sumant Patro 539 <Sumant.Patro@lsil.com> 5402 Current Version : 00.00.02.04 5413 Older Version : 00.00.02.02 542i. Register 16 byte CDB capability with scsi midlayer 543 544 "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." 547 548 -Joshua Giles <joshua_giles@dell.com> 549 5501 Release Date : Mon Jan 23 14:09:01 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5512 Current Version : 00.00.02.02 5523 Older Version : 00.00.02.01 553 554i. 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. 556 557 -Sumant Patro <Sumant.Patro@lsil.com> 558 5591 Release Date : Mon Dec 19 14:36:26 PST 2005 - Sumant Patro <Sumant.Patro@lsil.com> 5602 Current Version : 00.00.02.00-rc4 5613 Older Version : 00.00.02.01 562 563i. Code reorganized to remove code duplication in megasas_build_cmd. 564 565 "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" 566 567 - Christoph Hellwig <hch@lst.de> 568 569ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems. 570 571 "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" 572 573 - Christoph Hellwig <hch@lst.de> 574
