Add the Online Controller Reset (OCR) to the Driver. 109 OCR is the new feature for megaraid_sas driver which 110 will allow the fw to do the chip reset which will not 111 affact the OS behavious. 112 113 To add the OCR support, driver need to do: 114 a). reset the controller chips -- Xscale and Gen2 which 115 will change the function calls and add the reset function 116 related to this two chips. 117 118 b). during the reset, driver will store the pending cmds 119 which not returned by FW to driver's pending queue. Driver 120 will re-issue those pending cmds again to FW after the OCR 121 finished. 122 123 c). In driver's timeout routine, driver will report to 124 OS as reset. Also driver's queue routine will block the 125 cmds until the OCR finished. 126 127 d). in Driver's ISR routine, if driver get the FW state as 128 state change, FW in Failure status and FW support online controller 129 reset (OCR), driver will start to do the controller reset. 130 131 e). In driver's IOCTL routine, the application cmds will wait for the 132 OCR to finish, then issue the cmds to FW. 133 134 f). Before driver kill adapter, driver will do last chance of 135 OCR to see if driver can bring back the FW. 136 1372. Add the support update flag to the driver to tell LSI megaraid_sas 138 application which driver will support the device update. So application 139 will not need to do the device update after application add/del the device 140 from the system. 1413. In driver's timeout routine, driver will do three time reset if fw is in 142 failed state. Driver will kill adapter if can't bring back FW after the 143 this three times reset. 1444. Add the input parameter max_sectors to 1MB support to our GEN2 controller. 145 customer can use the input paramenter max_sectors to add 1MB support to GEN2 146 controller. 147 1481 Release Date : Thur.

Rollback the sense info implementation 258 Sense buffer ptr data type in the ioctl path is reverted back 259 to u32 * as in previous versions of driver. 260 2612. Fixed the driver frame count. 262 When Driver sent wrong frame count to firmware. As this 263 particular command is sent to drive, FW is seeing continuous 264 chip resets and so the command will timeout. 265 2663. Add the new controller(1078DE) support to the driver 267 and Increase the max_wait to 60 from 10 in the controller 268 operational status. With this max_wait increase, driver will 269 make sure the FW will finish the pending cmd for KDUMP case. 270 2711 Release Date : Thur.

Added module parameter "poll_mode_io" to support for "polling" 291 (reduced interrupt operation). In this mode, IO completion 292 interrupts are delayed. At the end of initiating IOs, the 293 driver schedules for cmd completion if there are pending cmds 294 to be completed. A timer-based interrupt has also been added 295 to prevent IO completion processing from being delayed 296 indefinitely in the case that no new IOs are initiated. 297 2981 Release Date : Fri.

Setting the max_sectors_per_req based on max SGL supported by the 307 FW. Prior versions calculated this value from controller info 308 (max_sectors_1, max_sectors_2). For certain controllers/FW, 309 this was resulting in a value greater than max SGL supported 310 by the FW. Issue was first reported by users running LUKS+XFS 311 with megaraid_sas. Thanks to RB for providing the logs and 312 duplication steps that helped to get to the root cause of the 313 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 314 10. FW may take a max of 60 seconds to respond to the INIT 315 cmd. 316 3171 Release Date : Fri.

When MegaSAS driver receives reset call from OS, driver waits in reset 344routine for max 3 minutes for all pending command completion. Now driver will 345call completion routine every 5 seconds from the reset routine instead of 346waiting for depending on cmd completion from isr path. 347 3481 Release Date : Mon Apr. 30 10:25:52 PST 2007 - 349 (emaild-id:megaraidlinux@lsi.com) 350 Sumant Patro 351 Bo Yang 352 3532 Current Version : 00.00.03.11 3543 Older Version : 00.00.03.09 355 356 1.

Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors 400 401 Fix: The driver is now throttling IO. 402 Checks added in megasas_queue_command to know if FW is able to 403 process commands within timeout period. If number of retries 404 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is 405 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed 406 from the time cmds were last sent to FW. 407 408ii. FW enables WCE bit in Mode Sense cmd for drives that are configured 409 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical 410 Disks are exposed with WCE=1. User is advised to enable Write Back 411 mode only when the controller has battery backup. At this time 412 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. 4282. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead 429 (hw_crit_error=1).

Remove superflous instance_lock 497 498 gets rid of the otherwise superflous instance_lock and avoids an unsave 499 unsynchronized access in the error handler. 500 501 - Christoph Hellwig <hch@lst.de> 502 503 5041 Release Date : Wed Feb 03 14:31:44 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5052 Current Version : 00.00.02.04 5063 Older Version : 00.00.02.04 507 508i. Support for 1078 type (ppc IOP) controller, device id : 0x60 added. 509 During initialization, depending on the device id, the template members 510 are initialized with function pointers specific to the ppc or 511 xscale controllers. 512 513 -Sumant Patro <Sumant.Patro@lsil.com> 514 5151 Release Date : Fri Feb 03 14:16:25 PST 2006 - Sumant Patro 516 <Sumant.Patro@lsil.com> 5172 Current Version : 00.00.02.04 5183 Older Version : 00.00.02.02 519i. Register 16 byte CDB capability with scsi midlayer 520 521 "This patch properly registers the 16 byte command length capability of the 522 megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas 523 hardware supports 16 byte CDB's." 524 525 -Joshua Giles <joshua_giles@dell.com> 526 5271 Release Date : Mon Jan 23 14:09:01 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5282 Current Version : 00.00.02.02 5293 Older Version : 00.00.02.01 530 531i. New template defined to represent each family of controllers (identified by processor used). 532 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. 533 534 -Sumant Patro <Sumant.Patro@lsil.com> 535 5361 Release Date : Mon Dec 19 14:36:26 PST 2005 - Sumant Patro <Sumant.Patro@lsil.com> 5372 Current Version : 00.00.02.00-rc4 5383 Older Version : 00.00.02.01 539 540i. Code reorganized to remove code duplication in megasas_build_cmd. 541 542 "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" 543 544 - Christoph Hellwig <hch@lst.de> 545 546ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems. 547 548 "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" 549 550 - Christoph Hellwig <hch@lst.de> 551
