DISCLAIMER

==========

All files and instructions in this repo provided "as is", without any warranty 

and so on.



I've just got few sources and made them work together for myself and i'll be 

glad if my work will help someone else.



Apologize in advance for my English and note: this is my first repository 

publishing so i could do something wrong.



SYNOPSIS

========

This repository contains result of my little work with upgrading FreeBSD 7.0 

STABLE to FreeBSD 9.2 STABLE on production web server with MegaRAID SAS 8704ELP 

card on board which is not supported by the native FreeBSD mfi driver.



Files in this repository are based on stable versions of FreeBSD: 7.4, 8.2 and 

9.2 obtained using CVS and LSI MegaRAID Driver from an official LSI website:



Description: http://www.lsi.com/downloads/Public/MegaRAID%20Common%20Files/4.410.01.00_freebsd_components.txt.txt

Download: http://www.lsi.com/downloads/Public/MegaRAID%20Common%20Files/freebsd_components.tgz



According to LSI statement, this mfi driver supports all models below: 



MegaRAID SAS 9240-4i

MegaRAID SAS 9240-8i

MegaRAID SAS 9260-4i

MegaRAID SAS 9260CV-4i

MegaRAID SAS 9260-8i

MegaRAID SAS 9260CV-8i

MegaRAID SAS 9260DE-8i

MegaRAID SAS 9261-8i

MegaRAID SAS 9280-4i4e

MegaRAID SAS 9280-8e

MegaRAID SAS 9280DE-8e

MegaRAID SAS 9280-24i4e

MegaRAID SAS 9280-16i4e

MegaRAID SAS 9260-16i

MegaRAID SAS 8704ELP

MegaRAID SAS 8704EM2

MegaRAID SAS 8708ELP

MegaRAID SAS 8708EM2 

MegaRAID SAS 8880EM2

MegaRAID SAS 8888ELP



Also, current version of LSI's driver and driver from this repository does not 

supports Thunderbolt (whatever it is).



In my case mfi driver was statically built into kernel and works fine so far.



WHAT FOR?

=========

LSI mfi driver probably doesn't work as it is. At least mfiutil (native mfi tool 

from FreeBSD) can not be built with LSI sources and you won't be able to build

the world. 



Don't know if this is a real problem, because mfiutil won't work anyway and you 

will use MegaCli util from FreeBSD ports.



Also driver files have few typos, like it was never really tested.



WHAT IS IN REPO

===============

Repository contains directories for FreeBSD 7.4, 8.2 and 9.2 in which you'll 

find sources for mfi driver and mfiutil, ready for compilation. 



INSTALLATION INSTRUCTIONS

=========================

Upgrade FreeBSD step by step. In my case I went 7.0 => 7.4 => 8.2 => 9.2



1) Obtaining FreeBSD source



First, install cvsup from ports:



	cd /usr/ports/net/cvsup-without-gui

	make install clean



than copy sample config file to /usr/local/etc



	cp /usr/share/examples/cvsup/stable-supfile /usr/local/etc/

	

Edit this copied file and set host and required version of FreeBSD:



	default host=cvsup1.us.FreeBSD.org

	default release=cvs tag=RELENG_7



RELENG fetches STABLE version of sources. Change it to RELENG_8 or RELENG_9 if 

you need 8.2 STABLE or 9.2 STABLE.



Than fetch sources:



	cvsup -L 2 /usr/local/etc/stable-supfile

	

You are now ready to apply our mfi source.



2) Installing mfi source files (target dirs are always the same, source dir is

for 7.4 in this example): 



	cd /usr/src/sys/dev/mfi

	rm *

	cp /this_repo/bsd7/mfi/* ./

	cd /usr/src/sys/modules/mfi

	rm *

	cp /this_repo/bsd7/mfi_module/* ./

	cd /usr/src/usr.sbin/mfiutil/

	rm *

	cp /this_repo/bsd7/mfiutil/* ./

	

3) Adjusting installation files:



Open your kernel configuration file, for example

	

	ee /usr/src/sys/amd64/conf/GENERIC

	

make sure that this line is not commented:



	device          mfi		# LSI MegaRAID SAS



make sure that these lines are commented: 



#	device         cbb             # cardbus (yenta) bridge

#	device         mpt             # LSI-Logic MPT-Fusion

#	device         mps             # LSI-Logic MPT-Fusion 2



Save changes and close the file.

	

Open /usr/src/sys/conf/files



	ee /usr/src/sys/conf/files

	

Make sure that there is a line:

 

	dev/mfi/mfi_syspd.c   optional mfi

	

If there is no such line, add it after "dev/mfi/mfi_cam.c"	



Also, comment lines below, if there are any of them:



#           dev/mfi/mfi_fp.c      optional mfi

#           dev/mfi/mfi_tbolt.c   optional mfi



Last two lines are for thunderbolt support which is disabled in the driver 

provided by LSI.



Save changes and close the file. 



Congrats, you are now ready to build and install your world and kernel:
