11 Release Date : Thur. May 03, 2010 09:12:45 PST 2009 - 2 (emaild-id:megaraidlinux@lsi.com) 3 Bo Yang 4 52 Current Version : 00.00.04.31-rc1 63 Older Version : 00.00.04.17.1-rc1 7 81. Add the Online Controller Reset (OCR) to the Driver. 9 OCR is the new feature for megaraid_sas driver which 10 will allow the fw to do the chip reset which will not 11 affact the OS behavious. 12 13 To add the OCR support, driver need to do: 14 a). reset the controller chips -- Xscale and Gen2 which 15 will change the function calls and add the reset function 16 related to this two chips. 17 18 b). during the reset, driver will store the pending cmds 19 which not returned by FW to driver's pending queue. Driver 20 will re-issue those pending cmds again to FW after the OCR 21 finished. 22 23 c). In driver's timeout routine, driver will report to 24 OS as reset. Also driver's queue routine will block the 25 cmds until the OCR finished. 26 27 d). in Driver's ISR routine, if driver get the FW state as 28 state change, FW in Failure status and FW support online controller 29 reset (OCR), driver will start to do the controller reset. 30 31 e). In driver's IOCTL routine, the application cmds will wait for the 32 OCR to finish, then issue the cmds to FW. 33 34 f). Before driver kill adapter, driver will do last chance of 35 OCR to see if driver can bring back the FW. 36 372. Add the support update flag to the driver to tell LSI megaraid_sas 38 application which driver will support the device update. So application 39 will not need to do the device update after application add/del the device 40 from the system. 413. In driver's timeout routine, driver will do three time reset if fw is in 42 failed state. Driver will kill adapter if can't bring back FW after the 43 this three times reset. 444. Add the input parameter max_sectors to 1MB support to our GEN2 controller. 45 customer can use the input paramenter max_sectors to add 1MB support to GEN2 46 controller. 47 481 Release Date : Thur.

Add the new controller (0078, 0079) support to the driver 136 Those controllers are LSI's next generatation(gen2) SAS controllers. 137 1381 Release Date : Mon.June. 23 10:12:45 PST 2008 - 139 (emaild-id:megaraidlinux@lsi.com) 140 Sumant Patro 141 Bo Yang 142 1432 Current Version : 00.00.03.22 1443 Older Version : 00.00.03.20 145 1461. Add shutdown DCMD cmd to the shutdown routine to make FW shutdown proper. 1472. Unexpected interrupt occurs in HWR Linux driver, add the dumy readl pci flush will fix this issue. 148 1491 Release Date : Mon. March 10 11:02:31 PDT 2008 - 150 (emaild-id:megaraidlinux@lsi.com) 151 Sumant Patro 152 Bo Yang 153 1542 Current Version : 00.00.03.20-RC1 1553 Older Version : 00.00.03.16 156 1571. Rollback the sense info implementation 158 Sense buffer ptr data type in the ioctl path is reverted back 159 to u32 * as in previous versions of driver. 160 1612. Fixed the driver frame count. 162 When Driver sent wrong frame count to firmware. As this 163 particular command is sent to drive, FW is seeing continuous 164 chip resets and so the command will timeout. 165 1663. Add the new controller(1078DE) support to the driver 167 and Increase the max_wait to 60 from 10 in the controller 168 operational status. With this max_wait increase, driver will 169 make sure the FW will finish the pending cmd for KDUMP case. 170 1711 Release Date : Thur.

Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 10. FW may take 180 a max of 60 seconds to respond to the INIT cmd. 181 1821 Release Date : Fri. Sep. 07 16:30:43 PST 2007 - 183 (emaild-id:megaraidlinux@lsi.com) 184 Sumant Patro 185 Bo Yang 186 1872 Current Version : 00.00.03.15 1883 Older Version : 00.00.03.14 189 1901. Added module parameter "poll_mode_io" to support for "polling" 191 (reduced interrupt operation). In this mode, IO completion 192 interrupts are delayed. At the end of initiating IOs, the 193 driver schedules for cmd completion if there are pending cmds 194 to be completed. A timer-based interrupt has also been added 195 to prevent IO completion processing from being delayed 196 indefinitely in the case that no new IOs are initiated. 197 1981 Release Date : Fri. Sep. 07 16:30:43 PST 2007 - 199 (emaild-id:megaraidlinux@lsi.com) 200 Sumant Patro 201 Bo Yang 202 2032 Current Version : 00.00.03.14 2043 Older Version : 00.00.03.13 205 2061. Setting the max_sectors_per_req based on max SGL supported by the 207 FW. Prior versions calculated this value from controller info 208 (max_sectors_1, max_sectors_2). For certain controllers/FW, 209 this was resulting in a value greater than max SGL supported 210 by the FW. Issue was first reported by users running LUKS+XFS 211 with megaraid_sas. Thanks to RB for providing the logs and 212 duplication steps that helped to get to the root cause of the 213 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 214 10. FW may take a max of 60 seconds to respond to the INIT 215 cmd. 216 2171 Release Date : Fri.

When MegaSAS driver receives reset call from OS, driver waits in reset 244routine for max 3 minutes for all pending command completion. Now driver will 245call completion routine every 5 seconds from the reset routine instead of 246waiting for depending on cmd completion from isr path. 247 2481 Release Date : Mon Apr. 30 10:25:52 PST 2007 - 249 (emaild-id:megaraidlinux@lsi.com) 250 Sumant Patro 251 Bo Yang 252 2532 Current Version : 00.00.03.11 2543 Older Version : 00.00.03.09 255 256 1. Memory Manager for IOCTL removed for 2.6 kernels. 257 pci_alloc_consistent replaced by dma_alloc_coherent. With this 258 change there is no need of memory manager in the driver code 259 260 On Wed, 2007-02-07 at 13:30 -0800, Andrew Morton wrote: 261 > I suspect all this horror is due to stupidity in the DMA API. 262 > 263 > pci_alloc_consistent() just goes and assumes GFP_ATOMIC, whereas 264 > the caller (megasas_mgmt_fw_ioctl) would have been perfectly happy 265 > to use GFP_KERNEL. 266 > 267 > I bet this fixes it 268 269 It does, but the DMA API was expanded to cope with this exact case, so 270 use dma_alloc_coherent() directly in the megaraid code instead. The dev 271 is just &pci_dev->dev. 272 273 James <James.Bottomley@SteelEye.com> 274 275 3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver. 276 4. Hibernation support added 277 5. Performing diskdump while running IO in RHEL 4 was failing. Fixed. 278 2791 Release Date : Fri Feb. 09 14:36:28 PST 2007 - 280 (emaild-id:megaraidlinux@lsi.com) 281 Sumant Patro 282 Bo Yang 283 2842 Current Version : 00.00.03.09 2853 Older Version : 00.00.03.08 286 287i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors 288 289 The driver now waits for 10 seconds to elapse instead of 5 (as in 290 previous release) to resume IO. 291 2921 Release Date : Mon Feb. 05 11:35:24 PST 2007 - 293 (emaild-id:megaraidlinux@lsi.com) 294 Sumant Patro 295 Bo Yang 2962 Current Version : 00.00.03.08 2973 Older Version : 00.00.03.07 298 299i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors 300 301 Fix: The driver is now throttling IO. 302 Checks added in megasas_queue_command to know if FW is able to 303 process commands within timeout period. If number of retries 304 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is 305 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed 306 from the time cmds were last sent to FW. 307 308ii. FW enables WCE bit in Mode Sense cmd for drives that are configured 309 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical 310 Disks are exposed with WCE=1. User is advised to enable Write Back 311 mode only when the controller has battery backup. At this time 312 Synhronize cache is not supported by the FW. Driver will short-cycle 313 the cmd and return success without sending down to FW. 314 3151 Release Date : Sun Jan. 14 11:21:32 PDT 2007 - 316 Sumant Patro <Sumant.Patro@lsil.com>/Bo Yang 3172 Current Version : 00.00.03.07 3183 Older Version : 00.00.03.06 319 320i. bios_param entry added in scsi_host_template that returns disk geometry 321 information. 322 3231 Release Date : Fri Oct 20 11:21:32 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com>/Bo Yang 3242 Current Version : 00.00.03.06 3253 Older Version : 00.00.03.05 326 3271. 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. 3282. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead 329 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS 330 3311 Release Date : Mon Oct 02 11:21:32 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com> 3322 Current Version : 00.00.03.05 3333 Older Version : 00.00.03.04 334 335i.

Disable interrupt made as fn pointer as they are different for 1068 / 1078 363iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and 364 3 SGE for 32 bit SGL 365iv. Tasklet added for cmd completion 366v. If FW in operational state before firing INIT, now we send RESET Flag to FW instead of just READY. This is used to do soft reset. 367vi. megasas_ctrl_prop structure updated (based on FW struct) 368vii.

This change is done to support new controllers that has different processors and thus different register set. 433 434 -Sumant Patro <Sumant.Patro@lsil.com> 435 4361 Release Date : Mon Dec 19 14:36:26 PST 2005 - Sumant Patro <Sumant.Patro@lsil.com> 4372 Current Version : 00.00.02.00-rc4 4383 Older Version : 00.00.02.01 439 440i. Code reorganized to remove code duplication in megasas_build_cmd. 441 442 "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" 443 444 - Christoph Hellwig <hch@lst.de> 445 446ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems. 447 448 "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" 449 450 - Christoph Hellwig <hch@lst.de> 451
