Construction du paquet RPM OFED driver pour Xeon Phi

Intel fournit avec son Manycore Platform Software Stack (MPSS) un pilote pour OFED (utile pour l'InfiniBand notamment) sous la forme d'un paquet RPM. Le seul problème est qu'il n'est installable qu'avec la version de base du kernel de la RHEL/CentOS 6.4 (la 2.6.32-358).

Fort heureusement, Intel fournit également le src.rpm du paquet permettant une reconstruction.
Mais si on tente un
rpmbuild --rebuild ofed-driver-3.1-0.1.build0.fc13.src.rpm


Ce dernier échoue si le système fonctionne avec un kernel à jour (comme le 2.6.32-358.23.2) :

On remarque des redéclarations de fonctions et d'objets dans les en-têtes qui provoquent des erreurs de compilation.

En fait, les en-têtes du kernel standard (2.6.32-358) de la RHEL/CentOS 6.4 ne contiennent pas ces définitions, alors que les en-têtes d'un kernel mis à jour (2.6.32-358.23.2 par exemple) les contiennent et entrent en conflit avec celles du pilote OFED...

Il va donc falloir patcher les pilotes OFED contenus dans le src.rpm pour supprimer ces erreurs.

Voici comment procéder.

Préparation du système



  • Mettre à jour sa RHEL et sa CentOS


yum update


  • Vérifier que le système utilise bien une version à jour du kernel


uname -a


  • Installer les paquets nécessaires


yum install rpm-build redhat-lsb kernel-devel gcc

Modification de ofed-driver.src.rpm


Installation des en-têtes de mpss-modules pour un kernel à jour



  • Télécharger la dernière version du MPSS, l'extraire avec tar, puis aller dans mpss/src et reconstruire le paquet mpss-modules pour avoir les fichiers de développement de mpss-modules pour le kernel mis à jour


rpmbuild --rebuild mpss-modules-3.1-0.1.build0.el6.src.rpm


  • Installer le paquet mpss-modules-dev résultant


yum install ~/rpmbuild/RPMS/x86_64/mpss-modules-dev-2.6.32-358.23.2.el6.x86_64-3.1-0.1.build0.el6.x86_64.rpm

Patchage de ofed-driver



  • Dans le répertoire mpss/src, extraire le fichier ofed-driver-3.1-0.1.build0.fc13.src.rpm


rpm2cpio ofed-driver-3.1-0.1.build0.fc13.src.rpm | cpio -idmv


  • On obtient le fichier ofed-driver-3.1.tgz à extraire :


tar xfz ofed-driver-3.1.tgz


  • Aller dans ofed-driver-3.1/src/patches/2.6.32-EL6.1 et créer un 1er fichier patch pour ethtool.h :
