Add the Online Controller Reset (OCR) to the Driver. 91 OCR is the new feature for megaraid_sas driver which 92 will allow the fw to do the chip reset which will not 93 affact the OS behavious. 94 95 To add the OCR support, driver need to do: 96 a). reset the controller chips -- Xscale and Gen2 which 97 will change the function calls and add the reset function 98 related to this two chips. 99 100 b). during the reset, driver will store the pending cmds 101 which not returned by FW to driver's pending queue. Driver 102 will re-issue those pending cmds again to FW after the OCR 103 finished. 104 105 c). In driver's timeout routine, driver will report to 106 OS as reset. Also driver's queue routine will block the 107 cmds until the OCR finished. 108 109 d). in Driver's ISR routine, if driver get the FW state as 110 state change, FW in Failure status and FW support online controller 111 reset (OCR), driver will start to do the controller reset. 112 113 e). In driver's IOCTL routine, the application cmds will wait for the 114 OCR to finish, then issue the cmds to FW. 115 116 f). Before driver kill adapter, driver will do last chance of 117 OCR to see if driver can bring back the FW. 118 1192. Add the support update flag to the driver to tell LSI megaraid_sas 120 application which driver will support the device update. So application 121 will not need to do the device update after application add/del the device 122 from the system. 1233. In driver's timeout routine, driver will do three time reset if fw is in 124 failed state. Driver will kill adapter if can't bring back FW after the 125 this three times reset. 1264. Add the input parameter max_sectors to 1MB support to our GEN2 controller. 127 customer can use the input paramenter max_sectors to add 1MB support to GEN2 128 controller. 129 1301 Release Date : Thur.

Rollback the sense info implementation 240 Sense buffer ptr data type in the ioctl path is reverted back 241 to u32 * as in previous versions of driver. 242 2432. Fixed the driver frame count. 244 When Driver sent wrong frame count to firmware. As this 245 particular command is sent to drive, FW is seeing continuous 246 chip resets and so the command will timeout. 247 2483. Add the new controller(1078DE) support to the driver 249 and Increase the max_wait to 60 from 10 in the controller 250 operational status. With this max_wait increase, driver will 251 make sure the FW will finish the pending cmd for KDUMP case. 252 2531 Release Date : Thur.

Added module parameter "poll_mode_io" to support for "polling" 273 (reduced interrupt operation). In this mode, IO completion 274 interrupts are delayed. At the end of initiating IOs, the 275 driver schedules for cmd completion if there are pending cmds 276 to be completed. A timer-based interrupt has also been added 277 to prevent IO completion processing from being delayed 278 indefinitely in the case that no new IOs are initiated. 279 2801 Release Date : Fri.

Setting the max_sectors_per_req based on max SGL supported by the 289 FW. Prior versions calculated this value from controller info 290 (max_sectors_1, max_sectors_2). For certain controllers/FW, 291 this was resulting in a value greater than max SGL supported 292 by the FW. Issue was first reported by users running LUKS+XFS 293 with megaraid_sas. Thanks to RB for providing the logs and 294 duplication steps that helped to get to the root cause of the 295 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 296 10. FW may take a max of 60 seconds to respond to the INIT 297 cmd. 298 2991 Release Date : Fri.

When MegaSAS driver receives reset call from OS, driver waits in reset 326routine for max 3 minutes for all pending command completion. Now driver will 327call completion routine every 5 seconds from the reset routine instead of 328waiting for depending on cmd completion from isr path. 329 3301 Release Date : Mon Apr. 30 10:25:52 PST 2007 - 331 (emaild-id:megaraidlinux@lsi.com) 332 Sumant Patro 333 Bo Yang 334 3352 Current Version : 00.00.03.11 3363 Older Version : 00.00.03.09 337 338 1. Memory Manager for IOCTL removed for 2.6 kernels. 339 pci_alloc_consistent replaced by dma_alloc_coherent.

Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors 382 383 Fix: The driver is now throttling IO. 384 Checks added in megasas_queue_command to know if FW is able to 385 process commands within timeout period. If number of retries 386 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is 387 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed 388 from the time cmds were last sent to FW. 389 390ii. FW enables WCE bit in Mode Sense cmd for drives that are configured 391 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical 392 Disks are exposed with WCE=1. User is advised to enable Write Back 393 mode only when the controller has battery backup. At this time 394 Synhronize cache is not supported by the FW.

All megaraid_sas 505 hardware supports 16 byte CDB's." 506 507 -Joshua Giles <joshua_giles@dell.com> 508 5091 Release Date : Mon Jan 23 14:09:01 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5102 Current Version : 00.00.02.02 5113 Older Version : 00.00.02.01 512 513i. New template defined to represent each family of controllers (identified by processor used). 514 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. 515 516 -Sumant Patro <Sumant.Patro@lsil.com> 517 5181 Release Date : Mon Dec 19 14:36:26 PST 2005 - Sumant Patro <Sumant.Patro@lsil.com> 5192 Current Version : 00.00.02.00-rc4 5203 Older Version : 00.00.02.01 521 522i. Code reorganized to remove code duplication in megasas_build_cmd. 523 524 "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" 525 526 - Christoph Hellwig <hch@lst.de> 527 528ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems. 529 530 "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" 531 532 - Christoph Hellwig <hch@lst.de> 533
