[gentoo-user] Kernel Modules

[gentoo-user] Kernel Modules

[Ignas Anikevicius]

Hello list,

I was wondering if it is possible to have a tool with which it would be
possible to have external modules installed for _all_ kernel versions in
my computer. Now I am using 2.6.38 kernel, but would like to try 2.6.39
and the thing is that I would like to have tp_smapi and phc-intel
modules in both kernels. Is it possible to have it without any serious
hacking?

I have only 3 ideas how I could achieve that:
* Making a custom ebuild, which would build the modules, but install
itself as a different package depending on the kernel version (eg
tp_smapi-2.6.39-gentoo)?
* Making a custom ebuild, which would build the modules for all kernel
versions in one go... (is this possible?)
* patching the gentoo-sources each time.

Is any of these solutions sensible?

Cheers,
Ignas

kernel modules are CONFIG_PROTECTED, so they are not automatically
removed when you uninstall / remerge the package (you have to remove
them manually), so you just have to remerge the package after you change
the /usr/src/linux symlink
there is also the module-rebuild utility, that automatically remerges
packages that installed a kernel module

i.e.

ln -sfn linux-VERSION1 /usr/src/linux
module-rebuild -X rebuild
ln -sfn linux-VERSION2 /usr/src/linux
module-rebuild -X rebuild
...

you might have to do 
module-rebuild populate
before the first time...

why you making so much work for yourself?

set the /usr/src/linux symlink to each set of installed sources in turn,
 run emerge @module-rebuild
 or run module-rebuild rebuild

you could even script it

cd /usr/src
for I in linux-*
do
  ln -sfn $I linux
  module-rebuild rebuils
done

Fixing my bash syntax errors is left as an exercise for the interested reader

why not emerging them several times with linux pointing to the different 
kernels?

I that does not work:
ebuild .... unpack
ebuild .... compile
ebuild .... install
cp .ko from image directory to modules directory
depmod -ae

Thanks very much!

I am a former Arch user, so I was used for a lot of inconvenience while
doing such things, but gentoo seems to make my life easier and easier.

You actually don't need to the symlinks yourself.  Try:

   eselect kernel list

Then choose one with something like:

   eselect kernel set 2

Sure, but I can use ln in my sleep.

eselect OTOH, is something I always have to run bit by bit to recall the 
invocation. That's just way too much effort for this here old git....

Wasn't on this list that I saw the correct procedure for eselect?

eselect
eselect kernel
eselect kernel list
eselect kernel set 6

<sigh> It's so true....

I'm still not used to eselect and its options.  They are sensible but I 
just haven't got the hang of it.  I been practicing tho.  I do eselect 
modules list then go from there.  You are right tho Alan, in the end, it 
takes longer.  I bet it was supposed to save time too. lol

In my case there's usually a lot of wondering which one it is after step 1. 
Try this, poke around, nope. Try that, nope not that one. Sometime after the 
third try I find it.

On the whole, eselect is a good idea, just some of it's modules are extreme.

eselect opengl and eselect python are just two examples of things I have no 
idea how to accomplish manually

I'm okay with most of them, but whenever I need to use "eselect news"
my brain comes up empty.

Aha!  I had to memorise that because it kept popping up every time I would run 
emerge (and couldn't be bothered to run eselect at the time).  So it is:

  eselect news read new

it sort of rhymes.  ;-)

eselect bashcomp enable gentoo
eselect bashcomp enable eselect

I always do those when doing a new install. Of course, don't forget to do USE=bash-completion and the subsequent emerge --update --newuse --deep @world ;)

Never happened to me.  I simply enter "eselect" and then press TAB twice 
and get a list of every module :-P

You need to first incantate the 2-line spell I posted earlier, followed by a logout and a login.

And bash will from then on automagically provide a contextual command completion.

Oh.  Ohhhhh!!!  NEATO.  Now to remember I can do this the next time I 
can't remember the name of a module.  lol

Double neato !  It works after each option too.  Holy crap.  OK.  We 
need to start a thread and list all the NEATO things like this that 
others may not know about.  Sound like a idea?

Well, it's called bash completion and works pretty much for everything 
that has a completion file.  It needs "app-shells/bash-completion" to be 
installed.  There's a also global USE flag called bash-completion.

And also an eselect module called bashcomp, where you can enable this 
feature for specific tools and packages.  "eselect bashcomp list" shows 
the packages that support this.  For example, try "ls --<tab><tab>" and 
you get a list options.  Or gcc, or unrar, or...

This is one of those, 'I have heard of this but didn't know what is was' 
things.  I did set the USE flag and updated the needed things, -N and 
all, but this is pretty darn cool.

I notice a really long list of things when I do this:

eselect bashcomp list

Is there a way to just enable them all?  Is there some that should NOT 
be enabled, maybe for good reason?

Thanks.

The wiki has a bunch of info, including a command to set them all at
once. I've pasted it below, but e-mail formatting may ruin it.
http://en.gentoo-wiki.com/wiki/TAB-Completion

(quote)
If you want to enable all Bash tab-completions available for your system, type:

    if using eselect (just remove the --global option if you don't
want to enable them globally):

( shopt -s extglob; eselect bashcomp list | while read -r s; do
s="${s##*][[:space:]]}"; [[ $s != Available* ]] && eselect bashcomp
enable --global "${s%%?([[:space:]]\\*)}"; done )

Remember, for the changes to have an immediate effect, issue the
following command:
source /etc/bash/bashrc
(unquote)

Additional sources of fun info:

I was just starting to use the wiki when it crashed long ago.  After 
that, lots of stuff was missing so I haven't been back in a while.  I 
mostly learn off this list.  I don't even go to the forums much any more.

Looks like it would have a ALL option to me.  ;-)

Thanks for the link.  It is in process as I type.

Looks like maybe you didn't have the bash-completion USE flag set when
you emerged the eselect package.

Yes, that's why nothing more comes up in the list.  I was about to post this

Personally, I do some cherry-picking and enable a bashcomp when I found out I need it. I have 2 concerns (which may or may not be true):

1. It will make bash (or the whole system) slower

2. For some commands I *might* want the standard completion

That results in a short list of 'essential' bashcomps that I enable this way:

for m in $ESSENTIAL_BASHCOMP; do eselect bashcomp enable $m; done

Shove that line (prepended by ESSENTIAL_BASHCOMP) into a script, save the script somewhere safe and retrievable, and everytime I need to enable the bashcomp modules, I'll just download the script and execute it :)

So far, I'm just enjoying not having to type so much.  I'm not a great 
typer anyway so the less I have to do the better.

If I run into something that I don't want bash completion on, I can 
always disable it.  The man page tells how to do that but doesn't have a 
enable all option.

Since I have a quad core 3.2Ghz machine, I'm not to worried about 
speed.  I actually can't tell any difference, at least so far.  I may 
not do this on my old x86 rig tho.  It's a single 2500+ CPU and IDE 
drives.  That may slow things down there.

Thanks for sharing tho.  I'll keep that in mind when I mess with my old 
rig.

well, only when you are hitting tab ... ;)
I know it can be annoying to have to wait a long time when you
accidentally hit tab on a "complex" command..., but when you know how to
do the explicit filename only completion...

> 
> 2. For some commands I *might* want the standard completion

meta-/ (or  ESC then /) for the complete-filename, there are also others
for some other things (variable, username...)
man bash
/Completing

I'd like to use this but I don't have shopt. Which package is it in? If I 
ask Google I get a list of places to buy T-shirts.

Or just "eselect news read".

I found that while messing about trying to find out why one box listed news

It's a Bash built-in.

Hmm. It seems that the command from the Wiki can't be run as an ordinary 
user via sudo; that's what was causing the errors that made me think shopt 
was not on the system - I got "syntax error near unexpected token `shopt' "

Thanks.

Did you try: 
  sudo bash -c 'whatever'
?

Personally, I haven't used Gentoo's bash completion since 2009.

I don't really feel that I can trust it.
