50 2 Current Version : 00.00.04.31-rc1
51 3 Older Version : 00.00.04.17.1-rc1
53 1. Add the Online Controller Reset (OCR) to the Driver.
54 OCR is the new feature for megaraid_sas driver which
55 will allow the fw to do the chip reset which will not
56 affact the OS behavious.
58 To add the OCR support, driver need to do:
59 a). reset the controller chips -- Xscale and Gen2 which
60 will change the function calls and add the reset function
61 related to this two chips.
63 b). during the reset, driver will store the pending cmds
64 which not returned by FW to driver's pending queue. Driver
65 will re-issue those pending cmds again to FW after the OCR
66 finished.
68 c). In driver's timeout routine, driver will report to
69 OS as reset. Also driver's queue routine will block the
70 cmds until the OCR finished.
72 d). in Driver's ISR routine, if driver get the FW state as
73 state change, FW in Failure status and FW support online controller
74 reset (OCR), driver will start to do the controller reset.
76 e). In driver's IOCTL routine, the application cmds will wait for the
77 OCR to finish, then issue the cmds to FW.
79 f). Before driver kill adapter, driver will do last chance of
80 OCR to see if driver can bring back the FW.
82 2. Add the support update flag to the driver to tell LSI megaraid_sas
83 application which driver will support the device update. So application
84 will not need to do the device update after application add/del the device
85 from the system.
86 3. In driver's timeout routine, driver will do three time reset if fw is in
87 failed state. Driver will kill adapter if can't bring back FW after the
88 this three times reset.
89 4. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
90 customer can use the input paramenter max_sectors to add 1MB support to GEN2
91 controller.

100 1. Add the pad_0 in mfi frame structure to 0 to fix the
101 context value larger than 32bit value issue.

104 keep the logic drive list internal after driver load.

158 the tape device, set the pthru timeout to the os layer timeout value.
160 2. Add Poll_wait mechanism to Gen-2 Linux driv.
161 In the aen handler, driver needs to wakeup poll handler similar to
162 the way it raises SIGIO.

203 Sense buffer ptr data type in the ioctl path is reverted back
204 to u32 * as in previous versions of driver.
206 2. Fixed the driver frame count.
207 When Driver sent wrong frame count to firmware. As this
208 particular command is sent to drive, FW is seeing continuous
209 chip resets and so the command will timeout.
211 3. Add the new controller(1078DE) support to the driver
212 and Increase the max_wait to 60 from 10 in the controller
213 operational status. With this max_wait increase, driver will
214 make sure the FW will finish the pending cmd for KDUMP case.

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

251 1. Setting the max_sectors_per_req based on max SGL supported by the
252 FW. Prior versions calculated this value from controller info
253 (max_sectors_1, max_sectors_2). For certain controllers/FW,
254 this was resulting in a value greater than max SGL supported
255 by the FW. Issue was first reported by users running LUKS+XFS
256 with megaraid_sas. Thanks to RB for providing the logs and
257 duplication steps that helped to get to the root cause of the
258 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
259 10. FW may take a max of 60 seconds to respond to the INIT
260 cmd.

289 routine for max 3 minutes for all pending command completion. Now driver will
290 call completion routine every 5 seconds from the reset routine instead of
291 waiting for depending on cmd completion from isr path.

314 It does, but the DMA API was expanded to cope with this exact case, so
315 use dma_alloc_coherent() directly in the megaraid code instead. The dev
316 is just &pci_dev->dev.
318 James <James.Bottomley@SteelEye.com>
320 3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.
321 4. Hibernation support added

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

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