Here is the step by step recipe of kmview kernel module installation.

Contents

[edit] step 0

be aware that you are testing experimental software

[edit] step 1

download the kmview_kernel_module software from our svn repository on sourceforge

[edit] step 2 up to linux 2.6.37

download your favourite kernel (>2.6.22 <2.6.37). Check into the kernel_patches subdirectory that we have already updated the kernel patches for that kernel.

[edit] step 3 up to linux 2.6.37

download and install the latest utrace patches for the kernel you downloaded (from [1] or from [2])

[edit] steps 2-3 for kernels 3.0 and newer

get the utrace enabled source code from git: https://github.com/utrace e.g. 

 git clone git://github.com/utrace/linux utrace-3.2

[edit] step 4

(optional) apply also our ptrace patches (it is not needed for runninng kmview, it provides extensions to ptrace: this patch speeds up umview.)

[edit] step 5

compile and install the kernel as usual.

Note: We use kvm and qemu as a developing environment for kmview. If you want to test kmview without updating your kernel you can also have the kernel loaded by kvm or qemu: 

 $ kvm bzImage -append root=/dev/hda1 -m 256 -hda hd.image -net nic -net vde -monitor stdio

This command loads the kernel image on kvm (and starts a vde network connection to the main vde-switch).

[edit] step 6

change directory to the directory kmview_kernel_module you downloaded from our svn and type: 

 # make

if the new kernel has already been installed, otherwise type: 

 # make KERNELDIR="/path/to/your/kernel_source/"

[edit] step 7

boot the kernel, then run 

 # insmod kmview

[edit] step 8

create the device: 

 # mkdev /dev/kmview c 10 233
 # chmod 666 /dev/kmview

[edit] step 9

Compile kmview included in our svn repository (Directory UMVIEW). 

$ autoreconf -i
$ make
$ sudo make install

Now you can enjoy kmview.
