V\u00fdvoj\u00e1\u0159 cakehonolulu portoval Linux na hern\u00ed konzoli Atari Jaguar<\/a> v roce 1993. Na konzoli se poda\u0159ilo spustit j\u00e1dro Linux 7.2.0-rc1+ a minim\u00e1ln\u00ed u\u017eivatelsk\u00e9 prost\u0159ed\u00ed zalo\u017een\u00e9 na BusyBox, a to nejen na emul\u00e1toru, ale i na skute\u010dn\u00e9m hardwaru p\u0159es cartridge.<\/p>\n

\u00dakol nebyl trivi\u00e1ln\u00ed kv\u016fli architektu\u0159e Jaguar. Konzole m\u00e1 pouze 2 MB RAM, a\u017e 6 MB ROM na cartridgi a hlavn\u00ed procesor Motorola 68000 bez MMU. Pro takov\u00fd hardware obvykl\u00fd zp\u016fsob bootov\u00e1n\u00ed Linuxu nevyhovuje, proto v\u00fdvoj\u00e1\u0159 pou\u017eil NOMMU re\u017eim pro m68k\/uClinux a ploch\u00fd model pam\u011bti<\/a>.<\/p>\n

Aby se j\u00e1dro ve\u0161lo do omezen\u00ed konzole, bylo rozd\u011bleno mezi pam\u011bt\u00ed a cartridge: nem\u011bnn\u00e9 sekce jako .text a .rodata se prov\u00e1d\u011bj\u00ed p\u0159\u00edmo z ROM pl\u00e1nem XIP, zat\u00edmco m\u011bniteln\u00e9 .data a .bss jsou um\u00edst\u011bny v RAM. Pro \u010dasn\u00fd v\u00fdstup zpr\u00e1v byl pou\u017eit DSP \u010dip Jerry, kter\u00fd m\u00e1 s\u00e9riov\u00e9 linky TXD\/RXD a \u010dasova\u010de, a pozd\u011bji v\u00fdvoj\u00e1\u0159 p\u0159idal jednoduch\u00fd konzolov\u00fd ovlada\u010d pro \u010dip Tom, aby v\u00fdstup fungoval i na skute\u010dn\u00e9 konzoli. Tyto detaily jsou pops\u00e1ny v sekci o tom, co je pot\u0159eba pro zaveden\u00ed Linuxu na Jaguar<\/a>.<\/p>\n

U\u017eivatelsk\u00e9 prost\u0159ed\u00ed muselo b\u00fdt maxim\u00e1ln\u011b zredukov\u00e1no. Kv\u016fli absenci MMU se pou\u017e\u00edvaj\u00ed nikoli ELF soubory, ale FLAT bin\u00e1rky; BusyBox se spou\u0161t\u00ed p\u0159\u00edmo jako shell, bez standardn\u00ed instalace sady odkaz\u016f na applet, proto\u017ee to vedlo k nedostatku pam\u011bti. Tak\u00e9 byla pot\u0159eba konfigurace uClibc p\u0159es Buildroot, v\u010detn\u011b jednodu\u0161\u0161\u00ed strategie alokace pam\u011bti malloc-simple; v\u00edce je podrobn\u011b pops\u00e1no v sekci Userspace<\/a>.<\/p>\n

Praktick\u00fd p\u0159\u00ednos takov\u00e9ho portu je t\u00e9m\u011b\u0159 \u017e\u00e1dn\u00fd: Atari Jaguar se nest\u00e1v\u00e1 pohodln\u00fdm Linux po\u010d\u00edta\u010dem. Experiment v\u0161ak dob\u0159e ukazuje, jak daleko lze posunout podporu star\u00e9ho hardwaru v Linuxu a jak odoln\u00e1 z\u016fst\u00e1v\u00e1 architektura m68k.
