Erik Moqvist, auteur de la plateforme Simba<\/a><\/noindex> et des outils cantools<\/a><\/noindex>, d\u00e9veloppe une nouvelle distribution Monolinux<\/a><\/noindex>, ax\u00e9e sur la cr\u00e9ation de syst\u00e8mes Linux embarqu\u00e9s pour le lancement isol\u00e9 d'applications sp\u00e9cifiques \u00e9crites en C. Cette distribution se distingue par le fait que son contenu logiciel est pr\u00e9sent\u00e9 sous la forme d'un seul fichier ex\u00e9cutable statiquement li\u00e9, incluant tous les composants n\u00e9cessaires au fonctionnement de l'application (en substance, la distribution se compose du noyau Linux et d'un ram-disk avec un processus init statiquement li\u00e9, int\u00e9grant l'application et les biblioth\u00e8ques n\u00e9cessaires). Le code est distribu\u00e9<\/a><\/noindex> sous licence MIT.<\/p>\n

Dans l'environnement, toutes les sous-syst\u00e8mes et appels syst\u00e8me du noyau Linux sont fournis, y compris l'acc\u00e8s au FS, la pile r\u00e9seau et les pilotes de dispositifs. Les biblioth\u00e8ques disponibles pour lier \u00e0 l'application comprennent ml<\/a><\/noindex> (biblioth\u00e8que C de Monolinux avec shell, clients DHCP et NTP, Device-mapper, etc.), async<\/a><\/noindex> (cadre asynchrone), bitstream<\/a><\/noindex>, curl<\/a><\/noindex> (HTTP, FTP, \u2026), detools<\/a><\/noindex> (patchs delta), heatshrink<\/a><\/noindex> (algorithme de compression), humanfriendly<\/a><\/noindex> (outils auxiliaires), mbedTLS<\/a><\/noindex>, xz<\/a><\/noindex> et zlib<\/a><\/noindex>. Un cycle de d\u00e9veloppement rapide est pris en charge, permettant d'\u00e9valuer en quelques secondes une nouvelle version apr\u00e8s modification du code. <\/p>\n

Les variantes de Monolinux sont pr\u00e9par\u00e9es pour les cartes Raspberry Pi 3<\/a><\/noindex> et Jiffy<\/a><\/noindex>. La taille finale des assemblages est d'environ 800 Ko. La carte Jiffy<\/a><\/noindex> \u00e9quip\u00e9 d'un SoC i.MX6UL avec un CPU ARMv7-A (528 MHz), 1 Go de RAM DDR3 et 4 Go eMMC. Le temps de d\u00e9marrage de la carte Jiffy est de seulement 0,37 seconde \u2014 de l'allumage \u00e0 la disponibilit\u00e9 du syst\u00e8me de fichiers Ext4. Parmi ce temps, 1 ms est consacr\u00e9e \u00e0 l'initialisation mat\u00e9rielle du SoC, 184 ms \u00e0 l'ex\u00e9cution du code du firmware, 86 ms au fonctionnement du chargeur de d\u00e9marrage, 62 ms au d\u00e9marrage du noyau Linux et 40 ms \u00e0 l'activation d'Ext4. Le temps de red\u00e9marrage est de 0,26 seconde. En cas d'utilisation d'une pile r\u00e9seau, en raison des d\u00e9lais d'\u00e9tablissement de la connexion Ethernet et d'obtention des param\u00e8tres r\u00e9seau, le syst\u00e8me devient pr\u00eat pour l'interaction r\u00e9seau en 2,2 secondes. <\/p>\n

Le syst\u00e8me utilise le noyau Linux 4.14.78 dans une configuration minimale avec des des correctifs<\/a><\/noindex>, \u00e9liminant les retards inutiles dans le pilote MMC (MMC se connecte au firmware de la carte et au moment du d\u00e9marrage du pilote est d\u00e9j\u00e0 activ\u00e9) et initialisant les pilotes MMC et FEC (Ethernet) en mode parall\u00e8le.<\/p>\n
