 |
|
hi,
i installed the also driver correctly and sound worked well.
but after a kernel re-configuration/compilation, the modules
get lost.
what should i configure / patch / ... to get alsa along with
my kernel?
regards,
-didi |

emerge alsa-driver again.
After compiling a kernel, you should re-emerge addon modules (e.g. alsa, nvidia etc...).

thanks!
is there any chance to avoid this for each kernel
modification/compilation?

Hmm, I never tested it, but you can try to build the kernel without setting version information on modules.
This is in Loadable module support | Set version information on all module symbols.
To quote from the above option's help:
| Quote: | | CONFIG_MODVERSIONS: Usually, modules have to be recompiled whenever you switch to a new kernel. Saying Y here makes it possible, and safe, to use the same modules even after compiling a new kernel; this requires the program modprobe. All the software needed for module support is in the modutils package (check the file Documentation/Changes for location and latest version). NOTE: if you say Y here but don't have the program genksyms (which is also contained in the above mentioned modutils package), then the building of your kernel will fail. If you are going to use modules that are generated from non-kernel sources, you would benefit from this option. Otherwise it's not that important. So, N ought to be a safe bet. |
After that recompile the kernel and external modules, and from this point you can use the extrnal modules without compiling them after kernel recompilation.
I'd still recomend rebuiliding the modules if you switch kernel versions. It is safer and quote easy to do

About alsa-driver, how do I only make it compile for my soundcard? I don't need 40 or so modules for 40 different cards.
and about modversions, it isn't all that beautiful a system: when recompiling the whole kernel, versions md5's change and alsa modules become unusable again. only when recompiling modules, the system works.

To build only specific cards (from alsa-driver ebuild):
"If you want to only compile for specific card(s), set ALSA_CARDS environment variable accordingly".
So,
| Code: | | ALSA_CARDS="_the_cards_you_want" emerge alsa-driver |
