1311. Add the Online Controller Reset (OCR) to the Driver.
132 OCR is the new feature for megaraid_sas driver which
133 will allow the fw to do the chip reset which will not
134 affact the OS behavious.
135
136 To add the OCR support, driver need to do:
137 a). reset the controller chips -- Xscale and Gen2 which
138 will change the function calls and add the reset function
139 related to this two chips.
140
141 b). during the reset, driver will store the pending cmds
142 which not returned by FW to driver's pending queue. Driver
143 will re-issue those pending cmds again to FW after the OCR
144 finished.
145
146 c). In driver's timeout routine, driver will report to
147 OS as reset. Also driver's queue routine will block the
148 cmds until the OCR finished.
149
150 d). in Driver's ISR routine, if driver get the FW state as
151 state change, FW in Failure status and FW support online controller
152 reset (OCR), driver will start to do the controller reset.
153
154 e). In driver's IOCTL routine, the application cmds will wait for the
155 OCR to finish, then issue the cmds to FW.
156
157 f). Before driver kill adapter, driver will do last chance of
158 OCR to see if driver can bring back the FW.
159
1602. Add the support update flag to the driver to tell LSI megaraid_sas
161 application which driver will support the device update. So application
162 will not need to do the device update after application add/del the device
163 from the system.
1643. In driver's timeout routine, driver will do three time reset if fw is in
165 failed state. Driver will kill adapter if can't bring back FW after the
166 this three times reset.
1674. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
168 customer can use the input paramenter max_sectors to add 1MB support to GEN2
169 controller.

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

422i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
423
424 Fix: The driver is now throttling IO.
425 Checks added in megasas_queue_command to know if FW is able to
426 process commands within timeout period. If number of retries
427 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
428 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
429 from the time cmds were last sent to FW.
430
431ii. FW enables WCE bit in Mode Sense cmd for drives that are configured
432 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
433 Disks are exposed with WCE=1. User is advised to enable Write Back
434 mode only when the controller has battery backup. At this time
435 Synhronize cache is not supported by the FW. Driver will short-cycle

4501. 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.
4512. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
452 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

458i. PCI_DEVICE macro used
459
460 Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.

463ii. All compiler warnings removed
464iii. megasas_ctrl_info struct reverted to 3.02 release
465iv. Default value of megasas_dbg_lvl set to 0
466v. Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
467vi. In megasas_teardown_frame_pool(), cmd->frame was passed instead of
468 cmd->sense to pci_pool_free. Fixed. Bug was pointed out by

483i. Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
484 New varible added to set dbg level.
485ii. Disable interrupt made as fn pointer as they are different for 1068 / 1078
486iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
487 3 SGE for 32 bit SGL
488iv. Tasklet added for cmd completion
489v. 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.
490vi. megasas_ctrl_prop structure updated (based on FW struct)
491vii. Added print : FW now in Ready State during initialization

503i. Added support for ZCR controller.
504
505 New device id 0x413 added.
506
507ii. Bug fix : Disable controller interrupt before firing INIT cmd to FW.
508
509 Interrupt is enabled after required initialization is over.
510 This is done to ensure that driver is ready to handle interrupts when
511 it is generated by the controller.

532 During initialization, depending on the device id, the template members
533 are initialized with function pointers specific to the ppc or
534 xscale controllers.

554i. New template defined to represent each family of controllers (identified by processor used).
555 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.

569ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems.
570
571 "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"
