binary packages and use it. If there are no packages ready for your system, you
will have to install from sources (section 2) instead.
-These operations are made for installing the LTTng 0.4.2 tracer on a
-linux 2.6.12-rc4-mm2 kernel. You will also find instructions for installtion of
-LTTV 0.6.x : the Linux Trace Toolkit Viewer.
-
-At this point, the -mm tree of the kernel is used because it has RelayFS support
-in it. In a nearby future, a vanilla kernel 2.6.14 will be used, as RelayFS has
-been integrated in the linux 2.6.14-rc series.
+These operations are made for installing the LTTng 0.5.6 tracer on a
+linux 2.6.15 kernel. You will also find instructions for installation of
+LTTV 0.8.x : the Linux Trace Toolkit Viewer.
The following lttng patch is necessary to have the tracing hooks in the kernel.
The following ltt-control module controls the tracing.

** Section 1 * Installation from Debian or RPM packages **
***********************************************************
+** NOTE : RPM and debian packages are only made once a version has been
+ thoroughly tested. If they do not exist at the moment, please install from
+ sources (see section 2 below).
+
+
* Install from RPM packages on Fedora Core 4 :
Get LTTV RPM from :
http://ltt.polymtl.ca/packages/fedora/RPMS
-No RPM packages for LTTng are ready yet.
+LTTV RPM are ready.
+
+LTTng kernel and lttng-modules RPM are available for some architectures (i586,
+i686). Feel free to help fix the spec files to have correct lttng-modules RPM
+package.
* Install from Deb packages on Debian :
su -
apt-get update
apt-get install lttv lttv-doc
-apt-get install kernel-image-2.6.12-rc4-mm2-lttng-0.4.1
-apt-get install lttng-modules-modules-2.6.12-rc4-mm2-lttng-0.4.1
+apt-get install kernel-image-2.6.12-rc4-mm2-lttng-0.4.2
+apt-get install lttng-modules-modules-2.6.12-rc4-mm2-lttng-0.4.2
* note : the packages are signed by myself. I am not considered a trusted
Debian source yet, so warnings are normal.
su -
cd /usr/src
apt-get source lttv
-cd lttv-0.6.8
+cd lttv-0.6.9
dpkg-buildpackage -rfakeroot
You should then have your LTTV .deb files created for your architecture.
For building LTTng Debian packages :
su -
-apt-get install kernel-source-2.6.12-rc4-mm2-lttng-0.4.1
+apt-get install kernel-source-2.6.12-rc4-mm2-lttng-0.4.2
cd /usr/src
-bzip2 -cd kernel-source-2.6.12-rc4-mm2-lttng-0.4.1.tar.bz2 | tar xvof -
-cd kernel-source-2.6.12-rc4-mm2-lttng-0.4.1
+bzip2 -cd kernel-source-2.6.12-rc4-mm2-lttng-0.4.2.tar.bz2 | tar xvof -
+cd kernel-source-2.6.12-rc4-mm2-lttng-0.4.2
make menuconfig (or xconfig or config) (customize your configuration)
make-kpkg kernel_image
su -
cd /usr/src
apt-get source lttng-modules
-cd kernel-source-2.6.12-rc4-mm2-lttng-0.4.1
+cd kernel-source-2.6.12-rc4-mm2-lttng-0.4.2
make-kpkg --added_modules /usr/src/lttng-modules-0.3 modules_image
You will then see your freshly created .deb in /usr/src. Install it with
mkdir /usr/src/lttng
cd /usr/src/lttng

Items preceded by [*] means they has to be built into the kernel.
Items preceded by [M] means they has to be built as modules.
Items preceded by [ ] means they should be removed.

Select the following options :
[*] Linux Trace Toolkit Instrumentation Support
- [M] or [*] Linux Trace Toolkit Tracer
+ <M> or <*> Linux Trace Toolkit Tracer
It makes no difference for the rest of the procedure whether the Tracer
is compiled built-in or as a module.

+ [*] Align Linux Trace Toolkit Traces
do NOT activate (not ready yet) :
- [ ] Align Linux Trace Toolkit Traces
[ ] Activate Linux Trace Toolkit Heartbeat Timer
- IMPORTANT : This is enabled by default : you must disable it!
+ You may or may not activate instrumentation per facility. They are all
+ selected for logging by default. It can be used as a compile time filter to
+ enable/disable logging of events. It is useful to discard events with a
