http://www.kroah.com/lkn/

there. 

You can download it there. It helps you with building.

btw:
make -jX && make modules_install install

With make all modules_install install
or
make && make modules_install

you only have one make instance. Which is very slow.

I apply the update package.keywords and package.use ,but I still can't

This got a *lot* easier back when sysfs was added.

cd /sys/module//drivers/

And go from there

lspci will help you see the 'text' name for the device in question.

For example, let's say I don't know what the 'ahci' module is for.

$ cd /sys/module/ahci/drivers
$ ls
pci:ahci
$ cd pci\:ahci/
$ ls
:00:11.0  bind  module  new_id  remove_id  uevent  unbind
$ sudo lspci|grep 11.0
00:11.0 SATA controller: ATI Technologies Inc SB700/SB800 SATA
Controller [AHCI mode]
$

So now I know the ahci module manages my SATA controller.

Pretty sure we've all been there before. It helps to have some
foreknowledge about hardware standards and the like, but it's not
strictly necessary. As long as you're interested in *how* to find
information, and use that knowledge once you find it, I don't doubt
people will be interested in helping.

Came up with something possibly a little handier. This command should
tell you what driver is associated with every device on the system.

find /sys/devices -name driver -print0|xargs -0 ls -l|cut -d' '
-f10-|sed -e 's/\.\.\///g'

Output could probably still be a bit better cleaned up, but it should help.

Hi,

when I am setup a new system for example after changing the
motherboard and CPU for some reason, I normally boot into
a live sysrtem like ubuntoo or such, check whether the most
things are running and do a lsmod. Then I mount the tmp dir rw 
of my hd, which is on a separate filesystem, and paste all
valuable info on that like the output of lsmod, lsusb and such.

Then I use this infos for setting up a new kernel.

Only ashot in the dark...

HTH!
Best regards,
mcc

Your -f got stuck attached to the -d argument.

Wordwrap reconstruction fail. :-|

Try this for an alternate representation:

find /sys/devices -name driver \
  -print0|xargs -0 ls -l|cut -d' ' \

That worked better.  I did have to copy it from the email to kwrite,

No, that is not a better name for the USE flag.

Anyone who has read the docs for rxvt-unicode knows that the perl
extension is just that, an *extension*.  It is perfectly valid to
configure rxvt-unicode with --disable-perl.  And on some smaller
boxen it may even be necessary.  (Sometimes conserving ram is more
important than extra functionality.)

perl is the right USE flag for rxvt-unciode, and should remain a
USE flag.  It enables much more functionality than just the tabbed
extension, but does so at an expense.  An expense which is easily
noticed on smaller boxen.

Fair enough. I suspected the flag might enable plugins and considered
finding out what it actually does. But I didn't bother because I don't
use rxvt myself and that specific wasn't the point of my post anyway.

I still maintain the "perl" is not a good name for that flag. It does
not describe what the flag accomplishes, it describes an implementation
detail of how it is used. USE="perl" communicates very little; it might
communicate a lot to you if you know the guts of the app, but very
little to the casual observer wanting to find out what rxvt is.

I run into this kind of thing all the time, and not just with USE
flags, it's endemic amongst coders. The problem is best described like
so "high level description should expose what your code does, not how it
does it". I understand why coders make this kind of mistake -
expediency. It's easier to re-use the existing perl flag than to make a
whole new one in use.local.desc

For rxvt, a suitable flag name would be "plugins"

Or if there were some package-specific documentation that said, "perl:

In fact, that would be my favorite solution.

Agree.

The current USE flags are already proper.

What's lacking is a list of consequences for disabling/enabling each
applicable flag.
