>&#13;The goal of this guide is not to describe the Linux Trace Toolkit project in
details, as it is a
seperate project for now. It just gives pointers to the basic steps you must
take in order to generate a trace suitable for conversion.

><P
>&#13;First, go to the <A
HREF="http://ltt.polymtl.ca"
TARGET="_top"
>ltt.polymtl.ca</A
>
website, in the "Patches for the Official LTT" section. Use the latest version
of patches available. The file name convention used goes like this : 
aaaaaa-x.x--bbbbb-y.y.patch. That means a patch made for aaaaa, release x.x,
that adds bbbbb, release y.y to it. Notice the presence of the -- sign that
separates the "from" field from the name of the patch applied. This way, it's
impossible to be mixed up on the specific sequence of patch application. I
suggest that you use the "relayfs", "ltt" and then "md" patches. The "md" patch
adds events useful to LTTV that are not in the official LTT.
</P
><P
>&#13;Once you have the patches you need, get the matching Linux kernel version, apply
the patches on it, configure it, install it, reboot with the new kernel. You then
have an instrumented kernel ready for tracing. If you have problems during this phase,
please refer to <A

instructions about how to recompile a kernel, see
