====== Rétroportage de pilote Nvidia & Cuda sur une Debian Stretch ======

===== Rétroportage de CUDA  sous Stretch =====

La Debian Stretch ne dispose que de la version 7.5 de CUDA et du pilote 364.19. Ces versions peuvent rapidement sembler insuffisantes pour ceux qui désirent utiliser les dernières fonctionnalités de CUDA 8 ou simplement utiliser les dernières cartes video Nvidia.


Voici la méthode permettant d'installer à partir d'un rétro-portage les paquets Nvidia ainsi que tout l'environnement associé. Au 29 août 2016, il est possible de récupérer la version 367.44 indispensable pour les cartes GTX1080. 11 se trouvant dans l'archive **experimental** : le module NVIDIA se construit correctement à l'installation par DKMS. L'environnement de développement, le 6.5.19, sera rétroporté directement de l'archive **experimental**.

<note warning>Pour une compilation dans SIDUS, ne pas oublier de monter le ''/proc''</note>

==== Purge des paquets Nvidia et CUDA originels ====

<code>
dpkg -l | egrep "nvidia|cuda|cupti|nvtoolsext|nvvm|nvctrl|nvcuvid|curand|cublas|cufft|cudart|cuinj|cusparse|libnpp" | awk '{ print $2 }' | xargs -I '{}' apt-get -y purge '{}'
dpkg -l | grep opencl | grep -v openclip | awk '{ print $2 }' | xargs -I '{}' apt-get -y purge '{}'
</code>

==== Préparation du système ====

Il est nécessaire d'insérer les sources des paquets sid et expérimentaux pour disposer de la dernière version de CUDA packagée.

<code>
apt-get install -y pbuilder pciutils debhelper quilt libgtk2.0-dev libjansson-dev libvdpau-dev libxv-dev libxxf86vm-dev dh-autoreconf

[ $(grep stretch /etc/apt/sources.list | grep deb-src | wc -l) -gt 0 ] && echo "Already present" || echo "deb-src http://ftp.fr.debian.org/debian/ sid main contrib non-free" >> /etc/apt/sources.list
[ $(grep sid /etc/apt/sources.list | grep deb-src | wc -l) -gt 0 ] && echo "Already present" || echo "deb-src http://ftp.fr.debian.org/debian/ sid main contrib non-free" >> /etc/apt/sources.list
[ $(grep experimental /etc/apt/sources.list | grep deb-src | wc -l) -gt 0 ] && echo "Already present" || echo "deb-src http://ftp.fr.debian.org/debian/ experimental main contrib non-free" >> /etc/apt/sources.list
aptitude -y update
</code>

==== Rétroportage des composants Système ====

<code>
