Drew DeVault p\u0159edstavil sv\u016fj nov\u00fd projekt \u2014 mikro j\u00e1dro Helios. V sou\u010dasn\u00e9 podob\u011b je projekt v po\u010d\u00e1te\u010dn\u00ed f\u00e1zi v\u00fdvoje a zat\u00edm podporuje pouze demonstra\u010dn\u00ed bootov\u00e1n\u00ed na syst\u00e9mech s architekturou x86_64. V budoucnu se pl\u00e1nuje podpora architektur iscv64 a aarch64. K\u00f3d projektu je naps\u00e1n v jazyce syst\u00e9mov\u00e9ho programov\u00e1n\u00ed Hare, bl\u00edzk\u00e9m C, s assemblerov\u00fdmi vlo\u017ekami a je distribuov\u00e1n pod licenc\u00ed GPLv3. Pro sezn\u00e1men\u00ed se se stavem v\u00fdvoje byl p\u0159ipraven testovac\u00ed iso obraz (1 MB). <\/p>\n

Architektura Helios je postavena s ohledem na koncepty mikroj\u00e1der seL4, ve kter\u00fdch jsou komponenty pro spr\u00e1vu zdroj\u016f j\u00e1dra um\u00edst\u011bny do prostoru u\u017eivatele a pro n\u011b se pou\u017e\u00edvaj\u00ed stejn\u00e9 prost\u0159edky pro rozd\u011blov\u00e1n\u00ed p\u0159\u00edstupu, jako pro u\u017eivatelsk\u00e9 zdroje. Mikroj\u00e1dro poskytuje minim\u00e1ln\u00ed mechanismy pro spr\u00e1vu p\u0159\u00edstupu k fyzick\u00e9mu adresn\u00edmu prostoru, p\u0159eru\u0161en\u00ed a zdroj\u016fm procesoru, zat\u00edmco vysoce \u00farov\u0148ov\u00e9 abstrakce ovlada\u010d\u016f pro interakci s hardwarem jsou realizov\u00e1ny odd\u011blen\u011b nad mikroj\u00e1drem ve form\u011b \u00faloh b\u011b\u017e\u00edc\u00edch na u\u017eivatelsk\u00e9 \u00farovni. <\/p>\n

V Helios je pou\u017eita model rozd\u011blen\u00ed p\u0159\u00edstupu zalo\u017een\u00fd na \"capability\". J\u00e1dro poskytuje primitiva pro alokaci str\u00e1nek pam\u011bti, odr\u00e1\u017een\u00ed fyzick\u00e9 pam\u011bti do adresn\u00edho prostoru, \u0159\u00edzen\u00ed \u00faloh a zpracov\u00e1n\u00ed po\u017eadavk\u016f na porty hardwarov\u00fdch za\u0159\u00edzen\u00ed.

V del\u0161\u00ed perspektiv\u011b se pl\u00e1nuje podpora SMP, IOMMU a VT-x. <\/p>\n

Pokud jde o u\u017eivatelsk\u00fd prostor, pl\u00e1nov\u00e1no je roz\u0161\u00ed\u0159en\u00ed n\u00edzko\u00farov\u0148ov\u00fdch slu\u017eeb a syst\u00e9mov\u00e9ho mana\u017eera Mercury, vrstvy kompatibility s POSIX (Luna), sb\u00edrky ovlada\u010d\u016f Venus, prost\u0159ed\u00ed pro v\u00fdvoj\u00e1\u0159e Gaia a r\u00e1mce pro testov\u00e1n\u00ed j\u00e1dra Vulcan.

Po tomto se o\u010dek\u00e1v\u00e1 vznik ovlada\u010d\u016f pro GPU AMD a desky Raspberry Pi. <\/p>\n

Jako d\u016fvod vzniku projektu se zmi\u0148uje touha po experimentech a pr\u00e1ce jako z\u00e1bava (princip \u201ejust for fun\u201c). Drew DeWalt r\u00e1d p\u0159ed sebou nastavuje ambici\u00f3zn\u00ed c\u00edle a pak, navzdory obecn\u00e9mu skepticismu, je realizuje.
