R: Dell2650/Perc 3Di: another victim

For everyone who wants to try compiling the aacraid kernel module, but never
compiled a kernel module before (like myself :-)) ... Mark's instruction are
just fine (thanks!), except for one minor detail: if you run "make
SUBDIRS=drivers/scsi/aacraid modules_install" it will overwrite your
/lib/modules/VERS-SUBCONFIG directory. Running mkinitrd would in this case
create an unusable initrd file.

The best solution seems to avoid running "make SUBDIRS=drivers/scsi/aacraid
modules_install", but instead copy the compiled module manually from
/usr/src/VERS/drivers/scsi/aacraid/aacraid.o to
/lib/modules/VERS-SUBCONFIG/kernel/drivers/scsi

It did work here. I'm not a kernel-compiling-guru, so it's doable :-)

I know I ask for it when I release sources ;->.

To compile a module based on the sources I am providing, on a RedHat kernel
source tree, perform the following steps. Your mileage will necessarily
vary, I tried my best to set up a cookbook to just build the module rather
than going through the strain of building *everything*. If anyone has
corrections, do not feel timid, tell us before `just enough information do
do oneself some harm' happens!

VERS is the kernel version, eg: RH7.3 is 2.4.18-3 etc
KERNVERS is the kernel version minus the EXTRAVERSION eg: RH7.3 is 2.4.18
DOWNLOADDIR is where you placed the aacraid driver source tarball AACVERS is
the aacraid driver version (eg 1.1.4-2256) CONFIG is your specific
configuration (eg: i686-smp) SUBCONFIG is your sub configuration (eg: smp)
You can use your favorite editor, I placed the `ed' interaction for a RH7.3
kernel, the idea is to make sure that the EXTRAVERSION in the Makefile
matches the kernel module you need to build.

# cd /usr/src/linux-VERS/drivers/scsi
# rm -rf aacraid
# tar -zxf DOWNLOADDIR/aacraid-AACVERS.tgz
# cd ../..
# make mrproper
# cp configs/kernel-KERNVERS-CONFIG.config .config
# ed Makefile
18746
/EXTRAVERSION
EXTRAVERSION = -3custom
s/custom/SUBCONFIG/p
w
q
# echo x | make menuconfig
# make dep
# make SUBDIRS=drivers/scsi/aacraid modules
# make SUBDIRS=drivers/scsi/aacraid modules_install

Then do a mkinitrd to set up the appropriate initrd image ... cross you
fingers that you do not have a pile of mudd when you are finished (it may be
a good idea to make a backup copy of the initrd image ;-> ).

I *really* hope this helps, distributing the all-seeing-all-knowing prebuild
rpm modules is a 14MB file. I do not have the resources, or the permission,
to provide those in a manner that would be timely enough to satisfy (1 month
+ matrix testing).

Sincerely -- Mark Salyzyn
