1001. 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.

300 (max_sectors_1, max_sectors_2). For certain controllers/FW,

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

391i. 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
André Goddard Rosaaf901ca2009-11-14 13:09:05 -0200405 the cmd and return success without sending down to FW.

433iii. megasas_ctrl_info struct reverted to 3.02 release
434iv. Default value of megasas_dbg_lvl set to 0
435v. Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
436vi. In megasas_teardown_frame_pool(), cmd->frame was passed instead of
437 cmd->sense to pci_pool_free. Fixed. Bug was pointed out by
438 Eric Sesterhenn

4423 Older Version : 00.00.03.03
443
444i. Added Reboot notify
445ii. Reduced by 1 max cmds sent to FW from Driver to make the reply_q_sz same
446 as Max Cmds FW can support

451
452i. Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
453 New varible added to set dbg level.
454ii. Disable interrupt made as fn pointer as they are different for 1068 / 1078
455iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
456 3 SGE for 32 bit SGL
457iv. Tasklet added for cmd completion
458v. 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.
459vi. megasas_ctrl_prop structure updated (based on FW struct)
460vii. Added print : FW now in Ready State during initialization

471
472i. Added support for ZCR controller.
473
474 New device id 0x413 added.
475
476ii. Bug fix : Disable controller interrupt before firing INIT cmd to FW.
477
478 Interrupt is enabled after required initialization is over.
479 This is done to ensure that driver is ready to handle interrupts when
480 it is generated by the controller.

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.

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.

532i. Code reorganized to remove code duplication in megasas_build_cmd.
533
534 "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"

536 - Christoph Hellwig <hch@lst.de>
537
538ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems.
539
540 "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"
