D\u00e9veloppeur cakehonolulu a port\u00e9 Linux sur la console de jeu Atari Jaguar<\/a> de 1993. Il a r\u00e9ussi \u00e0 charger le noyau Linux 7.2.0-rc1+ et un environnement utilisateur minimal bas\u00e9 sur BusyBox, cela ne concerne pas seulement un \u00e9mulateur, mais \u00e9galement un lancement sur du mat\u00e9riel r\u00e9el via une cartouche.<\/p>\n

<\/noindex> <\/p>\n

La t\u00e2che n'\u00e9tait pas triviale en raison de l'architecture Jaguar. La console dispose de seulement 2 Mo de RAM, jusqu'\u00e0 6 Mo de ROM sur la cartouche et d'un processeur principal Motorola 68000 sans MMU. Pour ce type de mat\u00e9riel, le sch\u00e9ma de chargement classique de Linux n'est pas adapt\u00e9, c'est pourquoi le d\u00e9veloppeur a utilis\u00e9 le mode NOMMU pour m68k\/uClinux et un mod\u00e8le de m\u00e9moire plate<\/a>.<\/p>\n

<\/noindex> <\/p>\n

Pour que le noyau s'ins\u00e8re dans les contraintes de la console, il a \u00e9t\u00e9 divis\u00e9 entre la m\u00e9moire et la cartouche : les sections immuables comme .text et .rodata s'ex\u00e9cutent directement depuis la ROM selon le sch\u00e9ma XIP, tandis que les sections modifiables .data et .bss sont plac\u00e9es en RAM. Pour la sortie pr\u00e9coce des messages, le chip DSP Jerry a \u00e9t\u00e9 utilis\u00e9, qui poss\u00e8de des lignes s\u00e9rie TXD\/RXD et des minuteries, et plus tard, le d\u00e9veloppeur a ajout\u00e9 un simple pilote de console pour le chip Tom, afin que la sortie fonctionne \u00e9galement sur la console r\u00e9elle. Ces d\u00e9tails sont d\u00e9crits dans la section sur ce qui est n\u00e9cessaire pour que Linux se charge sur le Jaguar<\/a>.<\/p>\n

L'environnement utilisateur a d\u00fb \u00eatre r\u00e9duit au minimum. En l'absence de MMU, des binaires FLAT sont utilis\u00e9s au lieu de fichiers ELF ; BusyBox est lanc\u00e9 directement comme shell, sans installation standard d'un ensemble de liens d'applet, car cela entra\u00eenait un manque de m\u00e9moire. Une configuration de uClibc via Buildroot a \u00e9galement \u00e9t\u00e9 n\u00e9cessaire, y compris une strat\u00e9gie d'allocation de m\u00e9moire malloc-simple plus simple ; cela est discut\u00e9 en d\u00e9tail dans la section Userspace<\/a>.<\/p>\n

<\/noindex> <\/p>\n

L'utilit\u00e9 pratique de ce port est quasi inexistante : l'Atari Jaguar ne devient pas un ordinateur Linux fonctionnel. Cependant, l'exp\u00e9rience montre bien jusqu'o\u00f9 il est possible d'\u00e9tendre le support de l'ancien mat\u00e9riel sous Linux et \u00e0 quel point l'architecture m68k reste robuste. Les sources du noyau modifi\u00e9 ont \u00e9t\u00e9 publi\u00e9es dans le d\u00e9p\u00f4t cakehonolulu\/linux_jag<\/a>.<\/p>\n
