Add shutdown DCMD cmd to the shutdown routine to make FW shutdown proper. 1002. Unexpected interrupt occurs in HWR Linux driver, add the dumy readl pci flush will fix this issue. 101 1021 Release Date : Mon. March 10 11:02:31 PDT 2008 - 103 (emaild-id:megaraidlinux@lsi.com) 104 Sumant Patro 105 Bo Yang 106 1072 Current Version : 00.00.03.20-RC1 1083 Older Version : 00.00.03.16 109 1101. Rollback the sense info implementation 111 Sense buffer ptr data type in the ioctl path is reverted back 112 to u32 * as in previous versions of driver. 113 1142. Fixed the driver frame count. 115 When Driver sent wrong frame count to firmware. As this 116 particular command is sent to drive, FW is seeing continuous 117 chip resets and so the command will timeout. 118 1193. Add the new controller(1078DE) support to the driver 120 and Increase the max_wait to 60 from 10 in the controller 121 operational status. With this max_wait increase, driver will 122 make sure the FW will finish the pending cmd for KDUMP case. 123 1241 Release Date : Thur. Nov. 07 16:30:43 PST 2007 - 125 (emaild-id:megaraidlinux@lsi.com) 126 Sumant Patro 127 Bo Yang 128 1292 Current Version : 00.00.03.16 1303 Older Version : 00.00.03.15 131 1321. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 10. FW may take 133 a max of 60 seconds to respond to the INIT cmd. 134 1351 Release Date : Fri. Sep. 07 16:30:43 PST 2007 - 136 (emaild-id:megaraidlinux@lsi.com) 137 Sumant Patro 138 Bo Yang 139 1402 Current Version : 00.00.03.15 1413 Older Version : 00.00.03.14 142 1431. Added module parameter "poll_mode_io" to support for "polling" 144 (reduced interrupt operation). In this mode, IO completion 145 interrupts are delayed. At the end of initiating IOs, the 146 driver schedules for cmd completion if there are pending cmds 147 to be completed. A timer-based interrupt has also been added 148 to prevent IO completion processing from being delayed 149 indefinitely in the case that no new IOs are initiated. 150 1511 Release Date : Fri. Sep. 07 16:30:43 PST 2007 - 152 (emaild-id:megaraidlinux@lsi.com) 153 Sumant Patro 154 Bo Yang 155 1562 Current Version : 00.00.03.14 1573 Older Version : 00.00.03.13 158 1591. Setting the max_sectors_per_req based on max SGL supported by the 160 FW. Prior versions calculated this value from controller info 161 (max_sectors_1, max_sectors_2). For certain controllers/FW, 162 this was resulting in a value greater than max SGL supported 163 by the FW. Issue was first reported by users running LUKS+XFS 164 with megaraid_sas. Thanks to RB for providing the logs and 165 duplication steps that helped to get to the root cause of the 166 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 167 10. FW may take a max of 60 seconds to respond to the INIT 168 cmd. 169 1701 Release Date : Fri.

When MegaSAS driver receives reset call from OS, driver waits in reset 197routine for max 3 minutes for all pending command completion. Now driver will 198call completion routine every 5 seconds from the reset routine instead of 199waiting for depending on cmd completion from isr path. 200 2011 Release Date : Mon Apr. 30 10:25:52 PST 2007 - 202 (emaild-id:megaraidlinux@lsi.com) 203 Sumant Patro 204 Bo Yang 205 2062 Current Version : 00.00.03.11 2073 Older Version : 00.00.03.09 208 209 1. Memory Manager for IOCTL removed for 2.6 kernels. 210 pci_alloc_consistent replaced by dma_alloc_coherent. With this 211 change there is no need of memory manager in the driver code 212 213 On Wed, 2007-02-07 at 13:30 -0800, Andrew Morton wrote: 214 > I suspect all this horror is due to stupidity in the DMA API. 215 > 216 > pci_alloc_consistent() just goes and assumes GFP_ATOMIC, whereas 217 > the caller (megasas_mgmt_fw_ioctl) would have been perfectly happy 218 > to use GFP_KERNEL. 219 > 220 > I bet this fixes it 221 222 It does, but the DMA API was expanded to cope with this exact case, so 223 use dma_alloc_coherent() directly in the megaraid code instead. The dev 224 is just &pci_dev->dev. 225 226 James <James.Bottomley@SteelEye.com> 227 228 3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver. 229 4. Hibernation support added 230 5. Performing diskdump while running IO in RHEL 4 was failing. Fixed. 231 2321 Release Date : Fri Feb. 09 14:36:28 PST 2007 - 233 (emaild-id:megaraidlinux@lsi.com) 234 Sumant Patro 235 Bo Yang 236 2372 Current Version : 00.00.03.09 2383 Older Version : 00.00.03.08 239 240i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors 241 242 The driver now waits for 10 seconds to elapse instead of 5 (as in 243 previous release) to resume IO. 244 2451 Release Date : Mon Feb. 05 11:35:24 PST 2007 - 246 (emaild-id:megaraidlinux@lsi.com) 247 Sumant Patro 248 Bo Yang 2492 Current Version : 00.00.03.08 2503 Older Version : 00.00.03.07 251 252i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors 253 254 Fix: The driver is now throttling IO. 255 Checks added in megasas_queue_command to know if FW is able to 256 process commands within timeout period. If number of retries 257 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is 258 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed 259 from the time cmds were last sent to FW. 260 261ii. FW enables WCE bit in Mode Sense cmd for drives that are configured 262 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical 263 Disks are exposed with WCE=1. User is advised to enable Write Back 264 mode only when the controller has battery backup. At this time 265 Synhronize cache is not supported by the FW. Driver will short-cycle 266 the cmd and return success without sending down to FW. 267 2681 Release Date : Sun Jan. 14 11:21:32 PDT 2007 - 269 Sumant Patro <Sumant.Patro@lsil.com>/Bo Yang 2702 Current Version : 00.00.03.07 2713 Older Version : 00.00.03.06 272 273i. bios_param entry added in scsi_host_template that returns disk geometry 274 information. 275 2761 Release Date : Fri Oct 20 11:21:32 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com>/Bo Yang 2772 Current Version : 00.00.03.06 2783 Older Version : 00.00.03.05 279 2801. 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. 2812. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead 282 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS 283 2841 Release Date : Mon Oct 02 11:21:32 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com> 2852 Current Version : 00.00.03.05 2863 Older Version : 00.00.03.04 287 288i. PCI_DEVICE macro used 289 290 Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines. 291 292 - Henrik Kretzschmar <henne@nachtwindheim.de> 293ii. All compiler warnings removed 294iii. megasas_ctrl_info struct reverted to 3.02 release 295iv. Default value of megasas_dbg_lvl set to 0 296v. Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl 297vi. In megasas_teardown_frame_pool(), cmd->frame was passed instead of 298 cmd->sense to pci_pool_free. Fixed.

Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead. 314 New varible added to set dbg level. 315ii. Disable interrupt made as fn pointer as they are different for 1068 / 1078 316iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and 317 3 SGE for 32 bit SGL 318iv. Tasklet added for cmd completion 319v. 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. 320vi. megasas_ctrl_prop structure updated (based on FW struct) 321vii. Added print : FW now in Ready State during initialization 322 3231 Release Date : Sun Aug 06 22:49:52 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com> 3242 Current Version : 00.00.03.02 3253 Older Version : 00.00.03.01 326 327i.

Support for 1078 type (ppc IOP) controller, device id : 0x60 added. 362 During initialization, depending on the device id, the template members 363 are initialized with function pointers specific to the ppc or 364 xscale controllers. 365 366 -Sumant Patro <Sumant.Patro@lsil.com> 367 3681 Release Date : Fri Feb 03 14:16:25 PST 2006 - Sumant Patro 369 <Sumant.Patro@lsil.com> 3702 Current Version : 00.00.02.04 3713 Older Version : 00.00.02.02 372i. Register 16 byte CDB capability with scsi midlayer 373 374 "Ths patch properly registers the 16 byte command length capability of the 375 megaraid_sas controlled hardware with the scsi midlayer. All megaraid_sas 376 hardware supports 16 byte CDB's." 377 378 -Joshua Giles <joshua_giles@dell.com> 379 3801 Release Date : Mon Jan 23 14:09:01 PST 2006 - Sumant Patro <Sumant.Patro@lsil.com> 3812 Current Version : 00.00.02.02 3823 Older Version : 00.00.02.01 383 384i. New template defined to represent each family of controllers (identified by processor used). 385 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. 386 387 -Sumant Patro <Sumant.Patro@lsil.com> 388 3891 Release Date : Mon Dec 19 14:36:26 PST 2005 - Sumant Patro <Sumant.Patro@lsil.com> 3902 Current Version : 00.00.02.00-rc4 3913 Older Version : 00.00.02.01 392 393i. Code reorganized to remove code duplication in megasas_build_cmd. 394 395 "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" 396 397 - Christoph Hellwig <hch@lst.de> 398 399ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems. 400 401 "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" 402 403 - Christoph Hellwig <hch@lst.de> 404
