[Solved] How do I make and install modules?

utente · n00b Joined: 12 Aug 2005 Posts: 17

OK, being a clueless noob as I am, let me ask the plain question...

Things I did:
I configured a 2.6.12-r8 kernel on an AMD64 platform with module support;
Configured some minor options (parallel port, gameport, TV cards and something else) to build as modules;
Done "make bzImage", "make modules", "make modules_install";
"cp arch/x86_64/boot/bzImage /boot/kernel-2.6.12-gentoo-r8";
"cp .config /boot/config-2.6.12-gentoo-r8";
"rm /etc/modules.d/kernel-2.6";
created above file as new with the list of modules just built (find /lib/modules/2.6.12-gentoo-r8/ -name ecc.ecc.); (UHM didn't took full pathnames, only module filenames as stated in the gentoo installation guide...)
"modules-update";
rebooted system.
Result: NOT A SINGLE MODULE LOADS at boot time ("FATAL: Module xxx not found" for each one). After the boot, the system is working but /proc/modules is empty, /proc/ksyms does not exist, there is no way to load any module with insmod or modprobe.

What did I do wrong?

uname -r returns "2.6.12-gentoo-r8".
The running kernel is the right one (the last I compiled), since uname -a returns the right timestamp...
other clues?

lsmod:
Module Size Used by
(nothing)

modprobe -ls:
the full content of /etc/modules.d/kernel-2.6 file, verbatim, but in reverse order (first rows last and vice versa)

modprobe foo:
FATAL: Module foo not found.

lsmod:
Module Size Used by
(nothing)

I put in /etc/modules.d/kernel-2.6 the full pathnames for each module, rebooting system now... BRB few minutes

Are you sure you did make modules_install? See if the modules are actually present:
ls -R /lib/modules/2.6.12-gentoo-r8/

Yes I am sure... modules are where they are supposed to be.

Putting full pathname in the /etc/modules.d/kernel-2.6 file didn't solved anything, I got the same errors.
Tried the same "lsmod + modprobe -ls + modprobe foo + lsmod" command sequence as above: same result. No change.

UPDATE: after rebooting, now there is ONE module installed!!!

lsmod:
Module Size Used by
ntfs 89664 1

Funny though... I configured NTFS support NOT to be modulixed, but builtin the kernel... :?:

Tried MODPROBE FOO: same old error: FATAL: Module foo not found...

UPDATE: at last I discovered that the file /lib/modules/2.6.12-gentoo-r8/modules.dep was empty.
So I ran depmod but it didn't had effect on modules.dep: so I did

depmod -n > /root/modulesdep.raw

to get a file to edit, to craft a working copy of modules.dep... and after doing this and edited the raw copy I take a look to the original modules.dep and... there were all of the dependency data!

I think there is something wrong with my depmod exe... however, now modprobe <module> works, modules are loaded and unloaded correctly and lsmod shows loaded modules. But, but... autoload script at boot still fails miserably to load any module

Oh well... maybe I should erase all that gentoo modules crap and write a good old "modprobe x modprobe y modprobe z..." script :wink:

put your good ol' modprobe x modprobe y modprobe z stuff in /etc/conf.d/local.start

FINAL UPDATE: now it's (almost) all OK.

Putting only the module names (no path & no extension) in the /etc/modules.autoload.d/kernel-2.6 fixed the autoload problem too. Now it's just the module fglrx (ATI RADEON graphic drivers) that refuses to load, but this should be another story...
I hope this thread be useful to someone else
