Drew DeVault predstavil svoj nov\u00fd projekt \u2014 mikrojadro Helios. V s\u00fa\u010dasnej podobe sa projekt nach\u00e1dza v po\u010diato\u010dnej f\u00e1ze v\u00fdvoja a zatia\u013e podporuje iba demonstra\u010dn\u00e9 spustenie na syst\u00e9moch s architekt\u00farou x86_64. V bud\u00facnosti pl\u00e1nuj\u00fa implementova\u0165 podporu architekt\u00far iscv64 a aarch64. K\u00f3d projektu je nap\u00edsan\u00fd v jazyku systematick\u00e9ho programovania Hare, ve\u013emi podobnom C, so zasunut\u00fdmi assemblerov\u00fdmi \u010das\u0165ami a je \u0161\u00edren\u00fd pod licenciou GPLv3. Na obozn\u00e1menie sa so stavom v\u00fdvoja bol pripraven\u00fd testovac\u00ed iso-obraz (1 MB). <\/p>\n

Architekt\u00fara Helios je postaven\u00e1 s oh\u013eadom na koncepty mikrojadra seL4, kde s\u00fa komponenty na riadenie zdrojov jadra presunut\u00e9 do pou\u017e\u00edvate\u013esk\u00e9ho priestoru a pre ne sa pou\u017e\u00edvaj\u00fa rovnak\u00e9 prostriedky na obmedzenie pr\u00edstupu, ako pre pou\u017e\u00edvate\u013esk\u00e9 zdroje. Mikrojadro poskytuje minim\u00e1lne mechanizmy na riadenie pr\u00edstupu k fyzick\u00e9mu adresn\u00e9mu priestoru, preru\u0161en\u00edm a procesorov\u00fdm zdrojom, pri\u010dom vysoko\u00farov\u0148ov\u00e9 abstrakcie ovl\u00e1da\u010dov na interakciu s hardv\u00e9rom s\u00fa implementovan\u00e9 samostatne nad mikrojadrom vo forme \u00faloh vykon\u00e1van\u00fdch na pou\u017e\u00edvate\u013eskej \u00farovni. <\/p>\n

V Helios sa uplat\u0148uje model pr\u00edstupov\u00fdch pr\u00e1v zalo\u017een\u00fd na \u201ecapability\u201c. Jadrou s\u00fa poskytovan\u00e9 primitivy na pridelenie str\u00e1n pam\u00e4te, mapovanie fyzickej pam\u00e4te do adresn\u00e9ho priestoru, spr\u00e1vu \u00faloh a spracovanie po\u017eiadaviek na porty hardv\u00e9rov\u00fdch zariaden\u00ed. Okrem slu\u017eieb jadra, ako je spr\u00e1va virtu\u00e1lnej pam\u00e4te, projekt tie\u017e pripravil ovl\u00e1da\u010de pre pr\u00e1cu s konzolou cez s\u00e9riov\u00fd port a BIOS VGA API. V nasleduj\u00facej f\u00e1ze v\u00fdvoja jadra bud\u00fa zabezpe\u010den\u00e9 preempt\u00edvna multitasking, IPC, PCI, spracovanie v\u00fdnimiek, anal\u00fdza tabuliek ACPI a obsluhy preru\u0161enia funguj\u00face v u\u017e\u00edvate\u013eskom priestore. V dlhodobej\u0161ej perspekt\u00edve sa pl\u00e1nuje implement\u00e1cia podpory SMP, IOMMU a VT-x. <\/p>\n

Pokia\u013e ide o u\u017e\u00edvate\u013esk\u00fd priestor, v pl\u00e1ne je rozvoj n\u00edzko\u00farov\u0148ov\u00fdch slu\u017eieb a syst\u00e9mov\u00e9ho mana\u017e\u00e9ra Mercury, vrstvy kompatibility s POSIX (Luna), zbierky ovl\u00e1da\u010dov Venus, prostredia pre v\u00fdvoj\u00e1rov Gaia a r\u00e1mca na testovanie jadra Vulcan. V\u00fdvoj prebieha s oh\u013eadom na pou\u017eitie na re\u00e1lnom hardv\u00e9ri \u2014 v po\u010diato\u010dnej f\u00e1ze sa pl\u00e1nuje vytvorenie ovl\u00e1da\u010dov pre ThinkPad vr\u00e1tane ovl\u00e1da\u010dov pre GPU Intel HD, HD Audio a Intel Gigabit Ethernet. Po tom sa o\u010dak\u00e1va vznik ovl\u00e1da\u010dov pre GPU AMD a dosky Raspberry Pi. <\/p>\n

Kone\u010dn\u00fdm cie\u013eom projektu je vytvorenie plnohodnotn\u00e9ho opera\u010dn\u00e9ho syst\u00e9mu Ares so svoj\u00edm bal\u00edkov\u00fdm mana\u017e\u00e9rom a grafick\u00fdm rozhran\u00edm. Ako d\u00f4vod vzniku projektu sa uv\u00e1dza t\u00fa\u017eba po experimentoch a pr\u00e1ca ako z\u00e1bava (princip «just for fun»). Drew DeWalt r\u00e1d stavia pred seba ambici\u00f3zne ciele a potom, napriek v\u0161eobecnej skepsi, ich realizuje. Tak tomu bolo s pou\u017e\u00edvate\u013esk\u00fdm prostred\u00edm Sway, e-mailov\u00fdm klientom Aerc, platformou pre spolupr\u00e1cu SourceHut a programovac\u00edm jazykom Hare. Ale aj ke\u010f nov\u00fd projekt nez\u00edska potrebn\u00e9 roz\u0161\u00edrenie, posl\u00fa\u017ei ako odrazov\u00fd bod pre v\u00fdvoj nov\u00fdch u\u017eito\u010dn\u00fdch syst\u00e9mov. Napr\u00edklad ladic\u00ed n\u00e1stroj vyvinut\u00fd pre Helios sa pl\u00e1nuje portova\u0165 na platformu Linux, pri\u010dom kni\u017enice na tvorbu grafick\u00e9ho rozhrania nebud\u00fa viazan\u00e9 na konkr\u00e9tnu platformu.
