+1.	Add the Online Controller Reset (OCR) to the Driver.

+
+	To add the OCR support, driver need to do: 
+		a). reset the controller chips -- Xscale and Gen2 which
+		will change the function calls and add the reset function
+		related to this two chips.
+		
+		b). during the reset, driver will store the pending cmds
+		which not returned by FW to driver's pending queue.  Driver
+		will re-issue those pending cmds again to FW after the OCR
+		finished.
+		
+		c). In driver's timeout routine, driver will report to
+		OS as reset. Also driver's queue routine will block the
+		cmds until the OCR finished.
+		
+		d). in Driver's ISR routine, if driver get the FW state as
+		state change, FW in Failure status and FW support online controller
+		reset (OCR), driver will start to do the controller reset.
+		
+		e). In driver's IOCTL routine, the application cmds will wait for the
+		OCR to finish, then issue the cmds to FW.
+		 
+		f). Before driver kill adapter, driver will do last chance of
+		OCR to see if driver can bring back the FW.

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain; charset="utf-8", Size: 2388 bytes --]

James,

Thanks for correcting that. Did you also applied 2/5, 3/5 and 4/5 patches?

By the way, I always use checkpatch.pl to check the patch before I attach the patch to the e-mail.  Also I just went to the 5/5 patch to verify the patch: the steps:

1. go to  http://marc.info/?l=linux-scsi&m=128688974201201&w=2 
2. click: ["megasas-version.patch" (application/octet-stream)] to download this patch.  
3. Used the checkpatch.pl to check (I used the cmd: "checkpatch.pl --no-tree megasas-version.patch") 

It looks OK for me (no errors).  It is maybe the checkpatch.pl I used does not get updated or some steps are not correct.  I will find out the updated one to try and find out the reasons.   


Thanks,

Bo Yang
