72 2 Current Version : 00.00.04.31-rc1
73 3 Older Version : 00.00.04.17.1-rc1
75 1. Add the Online Controller Reset (OCR) to the Driver.
76 OCR is the new feature for megaraid_sas driver which
77 will allow the fw to do the chip reset which will not
78 affact the OS behavious.
80 To add the OCR support, driver need to do:
81 a). reset the controller chips -- Xscale and Gen2 which
82 will change the function calls and add the reset function
83 related to this two chips.
85 b). during the reset, driver will store the pending cmds
86 which not returned by FW to driver's pending queue. Driver
87 will re-issue those pending cmds again to FW after the OCR
88 finished.
90 c). In driver's timeout routine, driver will report to
91 OS as reset. Also driver's queue routine will block the
92 cmds until the OCR finished.
94 d). in Driver's ISR routine, if driver get the FW state as
95 state change, FW in Failure status and FW support online controller
96 reset (OCR), driver will start to do the controller reset.
98 e). In driver's IOCTL routine, the application cmds will wait for the
99 OCR to finish, then issue the cmds to FW.
101 f). Before driver kill adapter, driver will do last chance of
102 OCR to see if driver can bring back the FW.
104 2. Add the support update flag to the driver to tell LSI megaraid_sas
105 application which driver will support the device update. So application
106 will not need to do the device update after application add/del the device
107 from the system.
108 3. In driver's timeout routine, driver will do three time reset if fw is in
109 failed state. Driver will kill adapter if can't bring back FW after the
110 this three times reset.
111 4. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
112 customer can use the input paramenter max_sectors to add 1MB support to GEN2
113 controller.

225 Sense buffer ptr data type in the ioctl path is reverted back
226 to u32 * as in previous versions of driver.
228 2. Fixed the driver frame count.
229 When Driver sent wrong frame count to firmware. As this
230 particular command is sent to drive, FW is seeing continuous
231 chip resets and so the command will timeout.
233 3. Add the new controller(1078DE) support to the driver
234 and Increase the max_wait to 60 from 10 in the controller
235 operational status. With this max_wait increase, driver will
236 make sure the FW will finish the pending cmd for KDUMP case.

257 1. Added module parameter "poll_mode_io" to support for "polling"
258 (reduced interrupt operation). In this mode, IO completion
259 interrupts are delayed. At the end of initiating IOs, the
260 driver schedules for cmd completion if there are pending cmds
261 to be completed. A timer-based interrupt has also been added
262 to prevent IO completion processing from being delayed
263 indefinitely in the case that no new IOs are initiated.

273 1. Setting the max_sectors_per_req based on max SGL supported by the
274 FW. Prior versions calculated this value from controller info
275 (max_sectors_1, max_sectors_2). For certain controllers/FW,
276 this was resulting in a value greater than max SGL supported
277 by the FW. Issue was first reported by users running LUKS+XFS
278 with megaraid_sas. Thanks to RB for providing the logs and
279 duplication steps that helped to get to the root cause of the
280 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
281 10. FW may take a max of 60 seconds to respond to the INIT
282 cmd.

336 It does, but the DMA API was expanded to cope with this exact case, so
337 use dma_alloc_coherent() directly in the megaraid code instead. The dev
338 is just &pci_dev->dev.
340 James <James.Bottomley@SteelEye.com>
342 3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.

366 i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
368 Fix: The driver is now throttling IO.
369 Checks added in megasas_queue_command to know if FW is able to
370 process commands within timeout period. If number of retries
371 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
372 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
373 from the time cmds were last sent to FW.
375 ii. FW enables WCE bit in Mode Sense cmd for drives that are configured
376 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
377 Disks are exposed with WCE=1. User is advised to enable Write Back
378 mode only when the controller has battery backup. At this time
379 Synhronize cache is not supported by the FW. Driver will short-cycle
380 the cmd and return success without sending down to FW.

498 i. New template defined to represent each family of controllers (identified by processor used).
499 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.

507 i. Code reorganized to remove code duplication in megasas_build_cmd.
509 "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"
511 - Christoph Hellwig <hch@lst.de>
513 ii. Defined MEGASAS_IOC_FIRMWARE32 for code paths that handles 32 bit applications in 64 bit systems.
515 "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"
