5 2 Current Version : 00.00.04.31-rc1
6 3 Older Version : 00.00.04.17.1-rc1
8 1. Add the Online Controller Reset (OCR) to the Driver.
9 OCR is the new feature for megaraid_sas driver which
10 will allow the fw to do the chip reset which will not
11 affact the OS behavious.
13 To add the OCR support, driver need to do:
14 a). reset the controller chips -- Xscale and Gen2 which
15 will change the function calls and add the reset function
16 related to this two chips.
18 b). during the reset, driver will store the pending cmds
19 which not returned by FW to driver's pending queue. Driver
20 will re-issue those pending cmds again to FW after the OCR
23 c). In driver's timeout routine, driver will report to
24 OS as reset. Also driver's queue routine will block the
25 cmds until the OCR finished.
27 d). in Driver's ISR routine, if driver get the FW state as
28 state change, FW in Failure status and FW support online controller
29 reset (OCR), driver will start to do the controller reset.
31 e). In driver's IOCTL routine, the application cmds will wait for the
32 OCR to finish, then issue the cmds to FW.
34 f). Before driver kill adapter, driver will do last chance of
35 OCR to see if driver can bring back the FW.
37 2. Add the support update flag to the driver to tell LSI megaraid_sas
38 application which driver will support the device update. So application
39 will not need to do the device update after application add/del the device
41 3. In driver's timeout routine, driver will do three time reset if fw is in
42 failed state. Driver will kill adapter if can't bring back FW after the
43 this three times reset.
44 4. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
45 customer can use the input paramenter max_sectors to add 1MB support to GEN2

55 1. Add the pad_0 in mfi frame structure to 0 to fix the
56 context value larger than 32bit value issue.
58 2. Add the logic drive list to the driver. Driver will
59 keep the logic drive list internal after driver load.

112 1. Add the Tape drive fix to the driver: If the command is for
113 the tape device, set the pthru timeout to the os layer timeout value.
115 2. Add Poll_wait mechanism to Gen-2 Linux driv.
116 In the aen handler, driver needs to wakeup poll handler similar to
117 the way it raises SIGIO.
119 3. Add new controller new SAS2 support to the driver.
121 4. Report the unconfigured PD (system PD) to OS.
123 5. Add the IEEE SGL support to the driver

154 2 Current Version : 00.00.03.20-RC1
155 3 Older Version : 00.00.03.16
157 1. Rollback the sense info implementation
158 Sense buffer ptr data type in the ioctl path is reverted back
159 to u32 * as in previous versions of driver.
161 2. Fixed the driver frame count.
162 When Driver sent wrong frame count to firmware. As this
163 particular command is sent to drive, FW is seeing continuous
164 chip resets and so the command will timeout.
166 3. Add the new controller(1078DE) support to the driver
167 and Increase the max_wait to 60 from 10 in the controller
168 operational status. With this max_wait increase, driver will
169 make sure the FW will finish the pending cmd for KDUMP case.

179 1. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 10. FW may take
180 a max of 60 seconds to respond to the INIT cmd.

187 2 Current Version : 00.00.03.15
188 3 Older Version : 00.00.03.14
190 1. Added module parameter "poll_mode_io" to support for "polling"
191 (reduced interrupt operation). In this mode, IO completion
192 interrupts are delayed. At the end of initiating IOs, the
193 driver schedules for cmd completion if there are pending cmds
194 to be completed. A timer-based interrupt has also been added
195 to prevent IO completion processing from being delayed
196 indefinitely in the case that no new IOs are initiated.

204 3 Older Version : 00.00.03.13
206 1. Setting the max_sectors_per_req based on max SGL supported by the
207 FW. Prior versions calculated this value from controller info
208 (max_sectors_1, max_sectors_2). For certain controllers/FW,
209 this was resulting in a value greater than max SGL supported
210 by the FW. Issue was first reported by users running LUKS+XFS
211 with megaraid_sas. Thanks to RB for providing the logs and
212 duplication steps that helped to get to the root cause of the
213 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
214 10. FW may take a max of 60 seconds to respond to the INIT

243 1. When MegaSAS driver receives reset call from OS, driver waits in reset
244 routine for max 3 minutes for all pending command completion. Now driver will
245 call completion routine every 5 seconds from the reset routine instead of
246 waiting for depending on cmd completion from isr path.

257 pci_alloc_consistent replaced by dma_alloc_coherent. With this
258 change there is no need of memory manager in the driver code

269 It does, but the DMA API was expanded to cope with this exact case, so
270 use dma_alloc_coherent() directly in the megaraid code instead. The dev
271 is just &pci_dev->dev.
273 James <James.Bottomley@SteelEye.com>
275 3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.
276 4. Hibernation support added
277 5. Performing diskdump while running IO in RHEL 4 was failing. Fixed.

287 i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
289 The driver now waits for 10 seconds to elapse instead of 5 (as in
290 previous release) to resume IO.

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

327 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.
328 2. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
329 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

431 i. New template defined to represent each family of controllers (identified by processor used).
432 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.
