0197 3 Older Version : 00.00.04.17.1-rc1
0198
0199 1. Add the Online Controller Reset (OCR) to the Driver.
0200 OCR is the new feature for megaraid_sas driver which
0201 will allow the fw to do the chip reset which will not
0202 affect the OS behavior.
0203
0204 To add the OCR support, driver need to do:
0205 a). reset the controller chips -- Xscale and Gen2 which
0206 will change the function calls and add the reset function
0207 related to this two chips.
0208
0209 b). during the reset, driver will store the pending cmds
0210 which not returned by FW to driver's pending queue. Driver
0211 will re-issue those pending cmds again to FW after the OCR
0212 finished.
0213
0214 c). In driver's timeout routine, driver will report to
0215 OS as reset. Also driver's queue routine will block the
0216 cmds until the OCR finished.
0217
0218 d). in Driver's ISR routine, if driver get the FW state as
0219 state change, FW in Failure status and FW support online controller
0220 reset (OCR), driver will start to do the controller reset.
0221
0222 e). In driver's IOCTL routine, the application cmds will wait for the
0223 OCR to finish, then issue the cmds to FW.
0224
0225 f). Before driver kill adapter, driver will do last chance of
0226 OCR to see if driver can bring back the FW.
0227
0228 2. Add the support update flag to the driver to tell LSI megaraid_sas
0229 application which driver will support the device update. So application
0230 will not need to do the device update after application add/del the device
0231 from the system.
0232 3. In driver's timeout routine, driver will do three time reset if fw is in
0233 failed state. Driver will kill adapter if can't bring back FW after the
0234 this three times reset.
0235 4. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
0236 customer can use the input parameter max_sectors to add 1MB support to GEN2
0237 controller.

0352 2. Fixed the driver frame count.
0353 When Driver sent wrong frame count to firmware. As this
0354 particular command is sent to drive, FW is seeing continuous
0355 chip resets and so the command will timeout.
0356

0358 and Increase the max_wait to 60 from 10 in the controller
0359 operational status. With this max_wait increase, driver will
0360 make sure the FW will finish the pending cmd for KDUMP case.

0382 (reduced interrupt operation). In this mode, IO completion
0383 interrupts are delayed. At the end of initiating IOs, the
0384 driver schedules for cmd completion if there are pending cmds
0385 to be completed. A timer-based interrupt has also been added
0386 to prevent IO completion processing from being delayed
0387 indefinitely in the case that no new IOs are initiated.

0397 1. Setting the max_sectors_per_req based on max SGL supported by the
0398 FW. Prior versions calculated this value from controller info
0399 (max_sectors_1, max_sectors_2). For certain controllers/FW,
0400 this was resulting in a value greater than max SGL supported
0401 by the FW. Issue was first reported by users running LUKS+XFS
0402 with megaraid_sas. Thanks to RB for providing the logs and
0403 duplication steps that helped to get to the root cause of the
0404 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
0405 10. FW may take a max of 60 seconds to respond to the INIT
0406 cmd.

0434 1. When MegaSAS driver receives reset call from OS, driver waits in reset
0435 routine for max 3 minutes for all pending command completion. Now driver will
0436 call completion routine every 5 seconds from the reset routine instead of
0437 waiting for depending on cmd completion from isr path.

0447 1. Memory Manager for IOCTL removed for 2.6 kernels.
0448 pci_alloc_consistent replaced by dma_alloc_coherent. With this
0449 change there is no need of memory manager in the driver code

0459
0460 It does, but the DMA API was expanded to cope with this exact case, so
0461 use dma_alloc_coherent() directly in the megaraid code instead. The dev
0462 is just &pci_dev->dev.

0464 James <James.Bottomley@SteelEye.com>
0465
0466 3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.
0467 4. Hibernation support added
0468 5. Performing diskdump while running IO in RHEL 4 was failing. Fixed.

0478 i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
0479
0480 The driver now waits for 10 seconds to elapse instead of 5 (as in
0481 previous release) to resume IO.

0489
0490 i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
0491
0492 Fix: The driver is now throttling IO.
0493 Checks added in megasas_queue_command to know if FW is able to
0494 process commands within timeout period. If number of retries
0495 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
0496 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
0497 from the time cmds were last sent to FW.
0498
0499 ii. FW enables WCE bit in Mode Sense cmd for drives that are configured
0500 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
0501 Disks are exposed with WCE=1. User is advised to enable Write Back
0502 mode only when the controller has battery backup. At this time
0503 Synhronize cache is not supported by the FW. Driver will short-cycle
0504 the cmd and return success without sending down to FW.

0517
0518 1. 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.
0519 2. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
0520 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

0528 Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.
0529
0530 - Henrik Kretzschmar <henne@nachtwindheim.de>
0531 ii. All compiler warnings removed
0532 iii. megasas_ctrl_info struct reverted to 3.02 release
0533 iv. Default value of megasas_dbg_lvl set to 0
0534 v. Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
0535 vi. In megasas_teardown_frame_pool(), cmd->frame was passed instead of
0536 cmd->sense to pci_pool_free. Fixed. Bug was pointed out by

0551 i. Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
0552 New variable added to set dbg level.
0553 ii. Disable interrupt made as fn pointer as they are different for 1068 / 1078
0554 iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
0555 3 SGE for 32 bit SGL
0556 iv. Tasklet added for cmd completion
0557 v. 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.
0558 vi. megasas_ctrl_prop structure updated (based on FW struct)
0559 vii. Added print : FW now in Ready State during initialization

0573 New device id 0x413 added.
0574
0575 ii. Bug fix : Disable controller interrupt before firing INIT cmd to FW.
0576
0577 Interrupt is enabled after required initialization is over.
0578 This is done to ensure that driver is ready to handle interrupts when
0579 it is generated by the controller.

0622 i. New template defined to represent each family of controllers (identified by processor used).
0623 The template will have definitions that will be initialised to appropriate 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.
