321. Rollback the sense info implementation
33 Sense buffer ptr data type in the ioctl path is reverted back
34 to u32 * as in previous versions of driver.
35
362. Fixed the driver frame count.
37 When Driver sent wrong frame count to firmware. As this
38 particular command is sent to drive, FW is seeing continuous
39 chip resets and so the command will timeout.
40
413. Add the new controller(1078DE) support to the driver
42 and Increase the max_wait to 60 from 10 in the controller
43 operational status. With this max_wait increase, driver will
44 make sure the FW will finish the pending cmd for KDUMP case.

651. Added module parameter "poll_mode_io" to support for "polling"
66 (reduced interrupt operation). In this mode, IO completion
67 interrupts are delayed. At the end of initiating IOs, the
68 driver schedules for cmd completion if there are pending cmds
69 to be completed. A timer-based interrupt has also been added
70 to prevent IO completion processing from being delayed
71 indefinitely in the case that no new IOs are initiated.

811. Setting the max_sectors_per_req based on max SGL supported by the
82 FW. Prior versions calculated this value from controller info
83 (max_sectors_1, max_sectors_2). For certain controllers/FW,
84 this was resulting in a value greater than max SGL supported
85 by the FW. Issue was first reported by users running LUKS+XFS
86 with megaraid_sas. Thanks to RB for providing the logs and
87 duplication steps that helped to get to the root cause of the
88 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
89 10. FW may take a max of 60 seconds to respond to the INIT
90 cmd.

1181. When MegaSAS driver receives reset call from OS, driver waits in reset
119routine for max 3 minutes for all pending command completion. Now driver will
120call completion routine every 5 seconds from the reset routine instead of
121waiting for depending on cmd completion from isr path.

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

143
144 It does, but the DMA API was expanded to cope with this exact case, so
145 use dma_alloc_coherent() directly in the megaraid code instead. The dev
146 is just &pci_dev->dev.

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

165 previous release) to resume IO.

173
174i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
175
176 Fix: The driver is now throttling IO.
177 Checks added in megasas_queue_command to know if FW is able to
178 process commands within timeout period. If number of retries
179 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
180 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
181 from the time cmds were last sent to FW.
182
183ii. FW enables WCE bit in Mode Sense cmd for drives that are configured
184 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
185 Disks are exposed with WCE=1. User is advised to enable Write Back
186 mode only when the controller has battery backup. At this time
187 Synhronize cache is not supported by the FW. Driver will short-cycle
188 the cmd and return sucess without sending down to FW.

2021. 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.
2032. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
204 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS

238iii. Frame count optimization. Main frame can contain 2 SGE for 64 bit SGLs and
239 3 SGE for 32 bit SGL
240iv. Tasklet added for cmd completion
241v. 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.
242vi. megasas_ctrl_prop structure updated (based on FW struct)

263 it is generated by the controller.
