will have to install from sources (section 2) instead.
-These operations are made for installing the LTTng 0.4.1 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 0.5.18 tracer on a

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 **
***********************************************************
-No RPM packages are ready yet.
-No Debian kernel LTTng patch is ready yet.
+** 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
+
+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 :
You can use the ltt.polymtl.ca apt source to get LTTV for Debian :
deb http://ltt.polymtl.ca/packages/debian experimental main
deb-src http://ltt.polymtl.ca/packages/debian experimental main
-Then, perform the following :
+
+* Install from precompiled binary packages (LTTV compiled only for i386, and
+ LTTng only for i686 smp), perform the following :
su -
apt-get update
apt-get install lttv lttv-doc
+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.
-Packages are only available for i386. If you want to create packages for other
-platforms, do :
+Then, follow the section "Editing the system wide configuration" in section 2.
+* Create custom LTTV Debian packages
+
+Binary packages are only available for i386. If you want to create your own LTTV
+packages for other platforms, do :
+
+su -
+cd /usr/src
apt-get source lttv
-cd lttv-0.6.7
+cd lttv-0.6.9
dpkg-buildpackage -rfakeroot
-You should then have your .deb files created for your architecture.
+You should then have your LTTV .deb files created for your architecture.
+
+* Create custom LTTng packages
+
+For building LTTng Debian packages :
+
+su -
+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-0.4.2.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
+
+You will then see your freshly created .deb in /usr/src. Install it with
+dpkg -i /usr/src/(image-name).deb
+
+You will also need to create a package for the lttng-modules :
+
+su -
+cd /usr/src
+apt-get source lttng-modules
+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
+dpkg -i /usr/src/lttng-modules-modules-(your version).deb
+
+Then, follow the section "Editing the system wide configuration" in section 2.

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.
- go to the "General setup" section

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.
+ activate :
+ [*] 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

+ Select the Linux 2.6.15-lttng-0.5.18 kernel in your boot loader.

+
+* Install the ltt-modules
+
+su -

+* Editing the system wide configuration
+
You must activate relayfs and specify a mount point. This is typically done in
fstab such that it happens at boot time.
cp /etc/fstab /etc/fstab.lttng.bkp
echo "relayfs /mnt/relayfs relayfs rw 0 0" >> /etc/fstab
-reboot
-
- Select the Linux 2.6.12-rc4-mm2-lttng-0.4.1 kernel in your boot loader.
+then, rebooting or issuing the following command will activate relayfs :
-
-* Install the ltt-modules
-
-su -
-cd /usr/src/lttng/lttng-modules-0.3
-KERNELDIR=/usr/src/linux-2.6.12-rc4-mm2-lttng-0.4.1 make
-KERNELDIR=/usr/src/linux-2.6.12-rc4-mm2-lttng-0.4.1 make modules_install
+mount /mnt/relayfs
You need to load the ltt-control module to be able to control tracing from user
space. This is done by issuing the command :
modprobe ltt-control
+If you want to have complete information about the kernel state (including all
+the process names), you need to load the ltt-statedump module. This is done by
+issuing the command :
+
+modprobe ltt-statedump
+
You can automate at boot time loading the ltt-control module by :
echo ltt-control >> /etc/modules
+echo ltt-statedump >> /etc/modules
