Intro

UPDATE: I updated the main list, please, if you can write in the main list, near the module name why you think this module should be removed from the default image. Please, also mark which modules you think should be included into the kernel, and which should remain as modules. Please prefix modules with M (keep as module) X (remove) or K (include into kernel)

Please update both the modules list and the lsmod list (don't paste yours, just add what you have, that we don't).

This list consists of all the kernel modules used in SHR by default, feel free to edit this page to add comments and suggest the removal of some. We know not all of those are necessary and that's why we created this page.

Discussion

No edits since this page was created. Maybe the problem is, that nobody knows what all the modules are for (like me). With that much modules it might be easier to start with an empty list and add necessary modules. And not with the complete list and removing modules. If some people provide the output of lsmod we should have a good starting point...

Removal Suggestions

Also, do we really need all these advanced packet filtering modules? Relaying a GPRS connection to a PC via USB network can be done with these modules:

kernel-module-ipt-masquerade
kernel-module-iptable-mangle
kernel-module-iptable-nat //AFAIK this one is required for tethering
kernel-module-xt-conntrack
kernel-module-iptable-filter

Needs clarification ^{Which modules should be removed (the ones referred to as "advanced").}

Alternative Proposal - Metapackages

Move modules out of the default install and into metapackages targeting particular use cases. Module packages can be a dependency of more than one metapackage. Users can then install metapackages for their use case without needing to know all the individual modules. See #948

Metapackages like this already exists see task-base-bluetooth, task-base-irda, task-base-usbgadget in  task-base.bb

All we need is to remove kernel-modules (metapackage with ALL kernel modules) from machine config om-gta02.conf and replace it with sane subset of modules:  om-gta02.conf.patch

BTW: don't forget to clean & rebuild task-base.bb of bump PR after MACHINE_EXTRA_RRECOMMENDS change.

After this change

Number of modules in feeds (for 2.6.29-rc3) => 310

Number of modules installed in image => 42

TAsn: This list doesn't include:

kernel-module-pl2303 - do we really need this?

and does include the oss modules which we probably don't need because we use alsa. and a coulpe of unwanted modules:

kernel-module-snd-mixer-oss
kernel-module-snd-pcm-oss

beniwtv: I think we should keep snd-pcm-oss. Some programs like Moocow can't play sound otherwise ;)

^{Then that package should depend on that module. This discussion is about modules included in image, all other modules will be avaible in feed. (Heinervdm)}
