27 2 Current Version : 00.00.04.31-rc1
28 3 Older Version : 00.00.04.17.1-rc1
30 1. Add the Online Controller Reset (OCR) to the Driver.
31 OCR is the new feature for megaraid_sas driver which
32 will allow the fw to do the chip reset which will not
33 affact the OS behavious.
35 To add the OCR support, driver need to do:
36 a). reset the controller chips -- Xscale and Gen2 which
37 will change the function calls and add the reset function
38 related to this two chips.
40 b). during the reset, driver will store the pending cmds
41 which not returned by FW to driver's pending queue. Driver
42 will re-issue those pending cmds again to FW after the OCR
43 finished.
45 c). In driver's timeout routine, driver will report to
46 OS as reset. Also driver's queue routine will block the
47 cmds until the OCR finished.
49 d). in Driver's ISR routine, if driver get the FW state as
50 state change, FW in Failure status and FW support online controller
51 reset (OCR), driver will start to do the controller reset.
53 e). In driver's IOCTL routine, the application cmds will wait for the
54 OCR to finish, then issue the cmds to FW.
56 f). Before driver kill adapter, driver will do last chance of
57 OCR to see if driver can bring back the FW.
59 2. Add the support update flag to the driver to tell LSI megaraid_sas
60 application which driver will support the device update. So application
61 will not need to do the device update after application add/del the device
62 from the system.
63 3. In driver's timeout routine, driver will do three time reset if fw is in
64 failed state. Driver will kill adapter if can't bring back FW after the
65 this three times reset.
66 4. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
67 customer can use the input paramenter max_sectors to add 1MB support to GEN2
68 controller.

77 1. Add the pad_0 in mfi frame structure to 0 to fix the
78 context value larger than 32bit value issue.
80 2. Add the logic drive list to the driver. Driver will
81 keep the logic drive list internal after driver load.

134 1. Add the Tape drive fix to the driver: If the command is for
135 the tape device, set the pthru timeout to the os layer timeout value.
137 2. Add Poll_wait mechanism to Gen-2 Linux driv.
138 In the aen handler, driver needs to wakeup poll handler similar to
139 the way it raises SIGIO.

179 1. Rollback the sense info implementation
180 Sense buffer ptr data type in the ioctl path is reverted back
181 to u32 * as in previous versions of driver.
183 2. Fixed the driver frame count.
184 When Driver sent wrong frame count to firmware. As this
185 particular command is sent to drive, FW is seeing continuous
186 chip resets and so the command will timeout.
188 3. Add the new controller(1078DE) support to the driver
189 and Increase the max_wait to 60 from 10 in the controller
190 operational status. With this max_wait increase, driver will
191 make sure the FW will finish the pending cmd for KDUMP case.

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

228 1. Setting the max_sectors_per_req based on max SGL supported by the
229 FW. Prior versions calculated this value from controller info
230 (max_sectors_1, max_sectors_2). For certain controllers/FW,
231 this was resulting in a value greater than max SGL supported
232 by the FW. Issue was first reported by users running LUKS+XFS
233 with megaraid_sas. Thanks to RB for providing the logs and
234 duplication steps that helped to get to the root cause of the
235 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
236 10. FW may take a max of 60 seconds to respond to the INIT
237 cmd.

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

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

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

349 1. 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.
350 2. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
351 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS
