 Hi,

 ist there a tool, which displays the dependencies of loaded modules as
 a tree like pstree does for tasks?

 Thank you very much for any help in advance! :)

 Well, it's not a tool and it cannot print to terminal but you might want
 to try out the bash skript below. It depends on media-gfx/graphviz to
 create a postscript file visualizing the dependencies. The file will be
 opened by your default postscript viewer (evince, okular, etc.).

 Hi Florian,
 
 thank you for your mail and the script.
 Unfortunately this is a little of a Lambourghini
 solution where a bicycle would completly suffice... ;)
 
 I had searched for a terminal related tool as pstree.

The problem with doing this non-graphically is that module dependencies
do not form a tree. They form a graph (multiple parents per child,
multiple childs per parent). Visualizing this likely exceeds the graphic
capabilities of terminals (you note that even with graphviz' advanced
automatic arrangement, there are still lines that cross half the image).

You could still create a tree, but only by making most modules appear
multiple times.

Florian Philipp

Just like the '--tree' option for 'emerge'

In that case something like:

# for m in `lsmod |awk '{print $1}'; do echo $m; modprobe \
  --show-depends $m|sed s'/^insmod \/.*\//  `-/;s/\.ko//'; done

[gentoo-user] pstree for modules ?

Hi,

ist there a tool, which displays the dependencies of loaded modules as
a tree like pstree does for tasks?

Thank you very much for any help in advance! :)
