184
1851. Add the Online Controller Reset (OCR) to the Driver.
186 OCR is the new feature for megaraid_sas driver which
187 will allow the fw to do the chip reset which will not
188 affact the OS behavious.
189
190 To add the OCR support, driver need to do:
191 a). reset the controller chips -- Xscale and Gen2 which
192 will change the function calls and add the reset function
193 related to this two chips.
194
195 b). during the reset, driver will store the pending cmds
196 which not returned by FW to driver's pending queue. Driver
197 will re-issue those pending cmds again to FW after the OCR
198 finished.
199
200 c). In driver's timeout routine, driver will report to
201 OS as reset. Also driver's queue routine will block the
202 cmds until the OCR finished.
203
204 d). in Driver's ISR routine, if driver get the FW state as
205 state change, FW in Failure status and FW support online controller
206 reset (OCR), driver will start to do the controller reset.
207
208 e). In driver's IOCTL routine, the application cmds will wait for the
209 OCR to finish, then issue the cmds to FW.
210
211 f). Before driver kill adapter, driver will do last chance of
212 OCR to see if driver can bring back the FW.
213
2142. Add the support update flag to the driver to tell LSI megaraid_sas
215 application which driver will support the device update. So application
216 will not need to do the device update after application add/del the device
217 from the system.
2183. In driver's timeout routine, driver will do three time reset if fw is in
219 failed state. Driver will kill adapter if can't bring back FW after the
220 this three times reset.
2214. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
222 customer can use the input paramenter max_sectors to add 1MB support to GEN2
223 controller.

384 FW. Prior versions calculated this value from controller info
385 (max_sectors_1, max_sectors_2). For certain controllers/FW,
386 this was resulting in a value greater than max SGL supported

4201. When MegaSAS driver receives reset call from OS, driver waits in reset
421routine for max 3 minutes for all pending command completion. Now driver will
422call completion routine every 5 seconds from the reset routine instead of
423waiting for depending on cmd completion from isr path.

433 1. Memory Manager for IOCTL removed for 2.6 kernels.
434 pci_alloc_consistent replaced by dma_alloc_coherent. With this
435 change there is no need of memory manager in the driver code

445
446 It does, but the DMA API was expanded to cope with this exact case, so
447 use dma_alloc_coherent() directly in the megaraid code instead. The dev
448 is just &pci_dev->dev.

452 3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.
453 4. Hibernation support added
454 5. Performing diskdump while running IO in RHEL 4 was failing. Fixed.

464i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
465
466 The driver now waits for 10 seconds to elapse instead of 5 (as in
467 previous release) to resume IO.

476i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
477
478 Fix: The driver is now throttling IO.
479 Checks added in megasas_queue_command to know if FW is able to
480 process commands within timeout period. If number of retries
481 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
482 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
483 from the time cmds were last sent to FW.
484
485ii. FW enables WCE bit in Mode Sense cmd for drives that are configured
486 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
487 Disks are exposed with WCE=1. User is advised to enable Write Back
488 mode only when the controller has battery backup. At this time
489 Synhronize cache is not supported by the FW. Driver will short-cycle
André Goddard Rosaaf901ca2009-11-14 13:09:05 -0200490 the cmd and return success without sending down to FW.

5041. 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.
5052. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
506 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

538 New varible added to set dbg level.
539ii. Disable interrupt made as fn pointer as they are different for 1068 / 1078
540iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
541 3 SGE for 32 bit SGL
542iv. Tasklet added for cmd completion
543v. 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.
544vi. megasas_ctrl_prop structure updated (based on FW struct)
545vii. Added print : FW now in Ready State during initialization

562
563 Interrupt is enabled after required initialization is over.
564 This is done to ensure that driver is ready to handle interrupts when
565 it is generated by the controller.

609 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.
