Hello,
I would like to modprobe my wireless driver kernel module at startup
automatically.
This works when I generate a rootfs and then boot up the first time so
the modules file gets generated and then I can manually add the kernel
module in that file and then reboot.
When I look in the manpage of update-modules it states that a config
file should be added in /etc/modutils but that directory is not in my
rootfs.
So I was wondering what I have to do to get /etc/modutils directory or
an other way to get the kernel module loaded at startup.
I am using the Poky 4.0 Laverne release.
Regards,
Gerard van den Bosch

I believe you can just add the name of the module to:
/etc/modules
Can you try that?

module_autoload_module_name to do that, is not supported in Poky?

I am not familiar with this technique.

That's true and that works but the problem is when I generate the rootfs the /etc/modules file isn't there.
It is generated by the update-modules script that is located in recipes-kernel, and as far as I can understand that script looks in /etc/modutils directory but I don't have that directory either.

Gerard

I've checked Poky 5.0 and according to git log it was there from the
beginning, so also in Poky 4.0. And also it's inherited by
linux-yocto(-stable).
if you read classes/kernel.bbclass you'll notice ie:
module_autoload_ipv6 = "ipv6"
which adds postinst to kernel-module-ipv6 package to "modprobe ipv6" and
also creates /etc/modutils/ipv6 file with "ipv6" in it to autoload ipv6
module after reboot.
similar
module_conf_bluez = "alias net-pf-31 bluez"
creates
/etc/modprobe.d/bluez.conf (or /etc/modutils/bluez.conf for 2.4 kernel)
with "alias net-pf-31 bluez"
and those files are added to kernel-module-something FILES, so removing
module removes autoload and config with it properly.

Added the following line to class/kernel.bbclass:
module_autoload_libertas-sdio = "libertas-sdio"
After that I rebuilded the kernel and generated the image but didn't get the modutils file and it didn't autoload either.
Also tried adding the line inside my kernel recipe after "inherit kernel" but that also didn't work.

This part I don't understand, how can I figure out what to alias?
With some googling I came across some list where it's major number related, but there is no difference between /proc/devices when I have the module loaded or not.

I was hoping to get to this today and got derailed on something else.
Would you please open a bug that we can use to track this. I'll get to
it as soon as I can.
