107
1081. Add the Online Controller Reset (OCR) to the Driver.
109 OCR is the new feature for megaraid_sas driver which
110 will allow the fw to do the chip reset which will not
111 affact the OS behavious.
112
113 To add the OCR support, driver need to do:
114 a). reset the controller chips -- Xscale and Gen2 which
115 will change the function calls and add the reset function
116 related to this two chips.
117
118 b). during the reset, driver will store the pending cmds
119 which not returned by FW to driver's pending queue. Driver
120 will re-issue those pending cmds again to FW after the OCR
121 finished.
122
123 c). In driver's timeout routine, driver will report to
124 OS as reset. Also driver's queue routine will block the
125 cmds until the OCR finished.
126
127 d). in Driver's ISR routine, if driver get the FW state as
128 state change, FW in Failure status and FW support online controller
129 reset (OCR), driver will start to do the controller reset.
130
131 e). In driver's IOCTL routine, the application cmds will wait for the
132 OCR to finish, then issue the cmds to FW.
133
134 f). Before driver kill adapter, driver will do last chance of
135 OCR to see if driver can bring back the FW.
136
1372. Add the support update flag to the driver to tell LSI megaraid_sas
138 application which driver will support the device update. So application
139 will not need to do the device update after application add/del the device
140 from the system.
1413. In driver's timeout routine, driver will do three time reset if fw is in
142 failed state. Driver will kill adapter if can't bring back FW after the
143 this three times reset.
1444. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
145 customer can use the input paramenter max_sectors to add 1MB support to GEN2
146 controller.

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

399i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
400
401 Fix: The driver is now throttling IO.
402 Checks added in megasas_queue_command to know if FW is able to
403 process commands within timeout period. If number of retries
404 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
405 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
406 from the time cmds were last sent to FW.
407
408ii. FW enables WCE bit in Mode Sense cmd for drives that are configured
409 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
410 Disks are exposed with WCE=1. User is advised to enable Write Back
411 mode only when the controller has battery backup. At this time
412 Synhronize cache is not supported by the FW. Driver will short-cycle
André Goddard Rosaaf901ca2009-11-14 13:09:05 -0200413 the cmd and return success without sending down to FW.

435i. PCI_DEVICE macro used
436
437 Convert the pci_device_id-table of the megaraid_sas-driver to the PCI_DEVICE-macro, to safe some lines.

440ii. All compiler warnings removed
441iii. megasas_ctrl_info struct reverted to 3.02 release
442iv. Default value of megasas_dbg_lvl set to 0
443v. Removing in megasas_exit the sysfs entry created for megasas_dbg_lvl
444vi. In megasas_teardown_frame_pool(), cmd->frame was passed instead of
445 cmd->sense to pci_pool_free. Fixed. Bug was pointed out by

452i. Added Reboot notify
453ii. Reduced by 1 max cmds sent to FW from Driver to make the reply_q_sz same
454 as Max Cmds FW can support

460i. Send stop adapter to FW & Dump pending FW cmds before declaring adapter dead.
461 New varible added to set dbg level.
462ii. Disable interrupt made as fn pointer as they are different for 1068 / 1078
463iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
464 3 SGE for 32 bit SGL
465iv. Tasklet added for cmd completion
466v. 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.
467vi. megasas_ctrl_prop structure updated (based on FW struct)
468vii. Added print : FW now in Ready State during initialization

480i. Added support for ZCR controller.
481
482 New device id 0x413 added.
483
484ii. Bug fix : Disable controller interrupt before firing INIT cmd to FW.
485
486 Interrupt is enabled after required initialization is over.
487 This is done to ensure that driver is ready to handle interrupts when
488 it is generated by the controller.

509 During initialization, depending on the device id, the template members
510 are initialized with function pointers specific to the ppc or
511 xscale controllers.

531i. New template defined to represent each family of controllers (identified by processor used).
532 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.

546ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems.
547
548 "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"
