 Posted: Tue Dec 20, 2005 6:14 pm Post subject: Looking for a Howto about compiling source kernel modules |
 |
|
Hello gentoo,
Can some one please point me to a guide explaining how to compile kernel modules that come as source into my kernel.
I'm tried of searching the web and not finding anything relevent.
I'm using a 2.6 ofcurse and tring (and failing) to compile a mpt fusion scsi controller into my kernel.
The thing is that this drivers comes either as an rpm or as source, which is cool if only I know how to compile it in.
Please (please) do me a favor and go over your bookmarks to pull me the link.
Ahhh.
Thank's,
Maxim.

I would go with the tar'd and bzip'd source code over the rpm.
Here's what I would do.
*Download the file
*First create a directory for the source file and put in in there before you extract it. Just in case the files are not compressed in a directory. untar/unzip it (varies depending how it was done) try | Code: | | tar -zxvf <file name> |
*look for a readme file or an install file and read it.. it should tell you how
If you can't fine the install/readme file with instructions, go into the source directory and try
| Code: | ./configure
make install
|
give me a link to the driver file and I can look at it. |

OK.. I've been looking around for a solution for you.. Looks like good news and bad news...
First of all the good news. It appears that there is already support for you in the 2.6.? kernel... sorry, I don't know when it was added, but it's in my 2.6.14-r2 gentoo sources
| Code: | grep -i fusion /usr/src/linux/.config
# Fusion MPT device support
# CONFIG_FUSION is not set
# CONFIG_FUSION_SPI is not set
# CONFIG_FUSION_FC is not set
# CONFIG_FUSION_SAS is not set
|
Have you tried these yet?
| Code: |
Device Drivers --->
Fusion MPT device support --->
< > Fusion MPT ScsiHost drivers for SPI
< > Fusion MPT ScsiHost drivers for FC
< > Fusion MPT ScsiHost drivers for SAS |
The bad news, it also appears that the Fusion-MPT controller is slow under several 2.6.x kernels.
http://seclists.org/lists/linux-kernel/2005/Nov/0180.html
If the controller is acting slow for you and you want to try the work-around, I recommend backing up your kernel source before hand. |

Thanks, that usefull.
I'm not using gentoo patched kernel.
I have downloaded the vanilla 2.6.14 source & the 2.6.15-rc6 patch and am trying to get this working (on serveral different distro's) for now the kernel compilies but I have another problem : The module doesn't find the controller and existed.
Even when I try to modprobe mptspi it.
Any ideas ?
b.t.w.
Thank you very much for helping me

umm.. not really.. Can you see the device with "lspci" ? Can you copy the exact error message here? What relivant information about your card is printed during boot and when you try to load the module?
__possibly__ you can try using the exact kernel that the patch was made for. If the ebuild isn't on your system, do an emerge sync.
| Code: | echo "=sys-kernel/vanilla-sources-2.6.15_rc6 ~x86" >> /etc/portage/package.keywords
emerge -vp =sys-kernel/vanilla-sources-2.6.15_rc6
emerge -v =sys-kernel/vanilla-sources-2.6.15_rc6 |
then apply your patch and try again. |
