Add the Online Controller Reset (OCR) to the Driver. 101 OCR is the new feature for megaraid_sas driver which 102 will allow the fw to do the chip reset which will not 103 affact the OS behavious. 104 105 To add the OCR support, driver need to do: 106 a). reset the controller chips -- Xscale and Gen2 which 107 will change the function calls and add the reset function 108 related to this two chips. 109 110 b). during the reset, driver will store the pending cmds 111 which not returned by FW to driver's pending queue. Driver 112 will re-issue those pending cmds again to FW after the OCR 113 finished. 114 115 c). In driver's timeout routine, driver will report to 116 OS as reset. Also driver's queue routine will block the 117 cmds until the OCR finished. 118 119 d). in Driver's ISR routine, if driver get the FW state as 120 state change, FW in Failure status and FW support online controller 121 reset (OCR), driver will start to do the controller reset. 122 123 e). In driver's IOCTL routine, the application cmds will wait for the 124 OCR to finish, then issue the cmds to FW. 125 126 f). Before driver kill adapter, driver will do last chance of 127 OCR to see if driver can bring back the FW. 128 1292. Add the support update flag to the driver to tell LSI megaraid_sas 130 application which driver will support the device update. So application 131 will not need to do the device update after application add/del the device 132 from the system. 1333. In driver's timeout routine, driver will do three time reset if fw is in 134 failed state. Driver will kill adapter if can't bring back FW after the 135 this three times reset. 1364. Add the input parameter max_sectors to 1MB support to our GEN2 controller. 137 customer can use the input paramenter max_sectors to add 1MB support to GEN2 138 controller. 139 1401 Release Date : Thur.

Rollback the sense info implementation 250 Sense buffer ptr data type in the ioctl path is reverted back 251 to u32 * as in previous versions of driver. 252 2532. Fixed the driver frame count. 254 When Driver sent wrong frame count to firmware. As this 255 particular command is sent to drive, FW is seeing continuous 256 chip resets and so the command will timeout. 257 2583. Add the new controller(1078DE) support to the driver 259 and Increase the max_wait to 60 from 10 in the controller 260 operational status. With this max_wait increase, driver will 261 make sure the FW will finish the pending cmd for KDUMP case. 262 2631 Release Date : Thur.

Added module parameter "poll_mode_io" to support for "polling" 283 (reduced interrupt operation). In this mode, IO completion 284 interrupts are delayed. At the end of initiating IOs, the 285 driver schedules for cmd completion if there are pending cmds 286 to be completed. A timer-based interrupt has also been added 287 to prevent IO completion processing from being delayed 288 indefinitely in the case that no new IOs are initiated. 289 2901 Release Date : Fri.

Setting the max_sectors_per_req based on max SGL supported by the 299 FW. Prior versions calculated this value from controller info 300 (max_sectors_1, max_sectors_2). For certain controllers/FW, 301 this was resulting in a value greater than max SGL supported 302 by the FW. Issue was first reported by users running LUKS+XFS 303 with megaraid_sas. Thanks to RB for providing the logs and 304 duplication steps that helped to get to the root cause of the 305 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 306 10. FW may take a max of 60 seconds to respond to the INIT 307 cmd. 308 3091 Release Date : Fri.

When MegaSAS driver receives reset call from OS, driver waits in reset 336routine for max 3 minutes for all pending command completion. Now driver will 337call completion routine every 5 seconds from the reset routine instead of 338waiting for depending on cmd completion from isr path. 339 3401 Release Date : Mon Apr. 30 10:25:52 PST 2007 - 341 (emaild-id:megaraidlinux@lsi.com) 342 Sumant Patro 343 Bo Yang 344 3452 Current Version : 00.00.03.11 3463 Older Version : 00.00.03.09 347 348 1. Memory Manager for IOCTL removed for 2.6 kernels. 349 pci_alloc_consistent replaced by dma_alloc_coherent.

Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors 392 393 Fix: The driver is now throttling IO. 394 Checks added in megasas_queue_command to know if FW is able to 395 process commands within timeout period. If number of retries 396 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is 397 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed 398 from the time cmds were last sent to FW. 399 400ii. FW enables WCE bit in Mode Sense cmd for drives that are configured 401 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical 402 Disks are exposed with WCE=1. User is advised to enable Write Back 403 mode only when the controller has battery backup. At this time 404 Synhronize cache is not supported by the FW. Driver will short-cycle 405 the cmd and return success without sending down to FW. 406 4071 Release Date : Sun Jan. 14 11:21:32 PDT 2007 - 408 Sumant Patro <Sumant.Patro@lsil.com>/Bo Yang 4092 Current Version : 00.00.03.07 4103 Older Version : 00.00.03.06 411 412i. bios_param entry added in scsi_host_template that returns disk geometry 413 information. 414 4151 Release Date : Fri Oct 20 11:21:32 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com>/Bo Yang 4162 Current Version : 00.00.03.06 4173 Older Version : 00.00.03.05 418 4191. 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. 4202. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead 421 (hw_crit_error=1).

Support for 1078 type (ppc IOP) controller, device id : 0x60 added. 501 During initialization, depending on the device id, the template members 502 are initialized with function pointers specific to the ppc or 503 xscale controllers. 504 505 -Sumant Patro <Sumant.Patro@lsil.com> 506 5071 Release Date : Fri Feb 03 14:16:25 PST 2006 - Sumant Patro 508 <Sumant.Patro@lsil.com> 5092 Current Version : 00.00.02.04 5103 Older Version : 00.00.02.02 511i. Register 16 byte CDB capability with scsi midlayer 512 513 "Ths patch properly registers the 16 byte command length capability of the 514 megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas 515 hardware supports 16 byte CDB's." 516 517 -Joshua Giles <joshua_giles@dell.com> 518 5191 Release Date : Mon Jan 23 14:09:01 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 5202 Current Version : 00.00.02.02 5213 Older Version : 00.00.02.01 522 523i. New template defined to represent each family of controllers (identified by processor used). 524 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. 525 526 -Sumant Patro <Sumant.Patro@lsil.com> 527 5281 Release Date : Mon Dec 19 14:36:26 PST 2005 - Sumant Patro <Sumant.Patro@lsil.com> 5292 Current Version : 00.00.02.00-rc4 5303 Older Version : 00.00.02.01 531 532i. Code reorganized to remove code duplication in megasas_build_cmd. 533 534 "There's a lot of duplicate code megasas_build_cmd.
