122 make sure the FW will finish the pending cmd for KDUMP case.

145 interrupts are delayed. At the end of initiating IOs, the
146 driver schedules for cmd completion if there are pending cmds
147 to be completed. A timer-based interrupt has also been added
148 to prevent IO completion processing from being delayed
149 indefinitely in the case that no new IOs are initiated.

1591. Setting the max_sectors_per_req based on max SGL supported by the
160 FW. Prior versions calculated this value from controller info
161 (max_sectors_1, max_sectors_2). For certain controllers/FW,
162 this was resulting in a value greater than max SGL supported
163 by the FW. Issue was first reported by users running LUKS+XFS
164 with megaraid_sas. Thanks to RB for providing the logs and
165 duplication steps that helped to get to the root cause of the
166 issue. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from
167 10. FW may take a max of 60 seconds to respond to the INIT
168 cmd.

221
222 It does, but the DMA API was expanded to cope with this exact case, so
223 use dma_alloc_coherent() directly in the megaraid code instead. The dev
224 is just &pci_dev->dev.

228 3. SYNCHRONIZE_CACHE is not supported by FW and thus blocked by driver.

252i. Under heavy IO mid-layer prints "DRIVER_TIMEOUT" errors
253
254 Fix: The driver is now throttling IO.
255 Checks added in megasas_queue_command to know if FW is able to
256 process commands within timeout period. If number of retries
257 is 2 or greater,the driver stops sending cmd to FW temporarily. IO is
258 resumed if pending cmd count reduces to 16 or 5 seconds has elapsed
259 from the time cmds were last sent to FW.
260
261ii. FW enables WCE bit in Mode Sense cmd for drives that are configured
262 as WriteBack. The OS may send "SYNCHRONIZE_CACHE" cmd when Logical
263 Disks are exposed with WCE=1. User is advised to enable Write Back
264 mode only when the controller has battery backup. At this time
265 Synhronize cache is not supported by the FW. Driver will short-cycle
André Goddard Rosaaf901ca2009-11-14 13:09:05 -0200266 the cmd and return success without sending down to FW.

2801. 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.
2812. Added check in megasas_queue_command and dpc/isr routine to see if we have already declared adapter dead
282 (hw_crit_error=1). If hw_crit_error==1, now we donot accept any processing of pending cmds/accept any cmd from OS
