This document describes one way to create the initrd directory hierarchy
|
||||||
|
in order to allow an initrd to be built into your kernel. The trick
|
||||||
|
here is to steal the initrd file used on your Linux laptop, Ubuntu in
|
||||||
|
this case. There are probably much better ways of doing this.
|
||||||
|
|
||||||
|
That said, here are the commands:
|
||||||
|
|
||||||
|
------------------------------------------------------------------------
|
||||||
|
zcat /initrd.img > /tmp/initrd.img.zcat
|
||||||
|
mkdir initrd
|
||||||
|
cd initrd
|
||||||
|
cpio -id < /tmp/initrd.img.zcat
|
||||||
|
------------------------------------------------------------------------
|
||||||
|
|
||||||
|
Interestingly enough, if you are running rcutorture, you don't really
|
||||||
|
need userspace in many cases. Running without userspace has the
|
||||||
|
advantage of allowing you to test your kernel independently of the
|
||||||
|
distro in place, the root-filesystem layout, and so on. To make this
|
||||||
|
happen, put the following script in the initrd's tree's "/init" file,
|
||||||
|
with 0755 mode.
|
||||||
|
|
||||||
|

This document describes one way to created the rcu-test-image file
|
||||||
|
that contains the filesystem used by the guest-OS kernel. There are
|
||||||
|
probably much better ways of doing this, and this filesystem could no
|

doubt be smaller. It is probably also possible to simply download
|
||||||
|
an appropriate image from any number of places.
