Drew DeVault predstavio je svoj novi projekt \u2014 mikrojezgru Helios. U svom trenutnom obliku, projekt je u ranoj fazi razvoja i podr\u017eava samo demonstracijsko pokretanje na sustavima s arhitekturom x86_64. U budu\u0107nosti planiraju implementirati podr\u0161ku za arhitekture iscv64 i aarch64. Izvorni kod projekta napisan je na jeziku sistemskog programiranja sli\u010dnom C-u, poznatom kao Hare, s in-line asembilerskim umetanjima, i distribuira se pod GPLv3 licencom. Za upoznavanje sa stanjem razvoja pripremljena je testna iso slika (1 MB). <\/p>\n

Arhitektura Helios izgra\u0111ena je s obzirom na koncept mikrojezgra seL4, u kojem su komponente za upravljanje resursima jezgre premje\u0161tene u prostor korisnika, a za njih se primjenjuju isti alati za ograni\u010davanje pristupa kao i za korisni\u010dke resurse. Mikrojezgro pru\u017ea minimalne mehanizme za upravljanje pristupom fizi\u010dkom adresnom prostoru, prekidima i resursima procesora, dok se visoko razine apstrakcije za upravljanje ure\u0111ajima implementiraju odvojeno iznad mikrojezgra u obliku zadataka koji se izvr\u0161avaju na korisni\u010dkoj razini. <\/p>\n

U Heliosu se primjenjuje model pristupne kontrole temeljen na 'capability'. Jezgra pru\u017ea primitivne alate za dodjelu stranica memorije, preslikavanje fizi\u010dke memorije u adresni prostor, upravljanje zadacima i obradu poziva prema portovima hardverskih ure\u0111aja. Osim kernel usluga, kao \u0161to su upravljanje virtualnom memorijom, projekt tako\u0111er obuhva\u0107a upravlja\u010dke programe za rad konzole putem serijskog porta i BIOS VGA API. Sljede\u0107a faza razvoja jezgre uklju\u010duje implementaciju preemptivne vi\u0161ezada\u0107nosti, IPC, PCI, obrade iznimaka, analizu ACPI tablica i prekida\u010de koji rade u korisni\u010dkom prostoru. U daljoj budu\u0107nosti planira se implementacija podr\u0161ke za SMP, IOMMU i VT-x. <\/p>\n

\u0160to se ti\u010de korisni\u010dkog prostora, planira se razvoj niskonivojskih usluga i sistemskog menad\u017eera Mercury, sloja kompatibilnosti s POSIX-om (Luna), kolekcije upravlja\u010dkih programa Venus, okru\u017eenja za programere Gaia i okvira za testiranje jezgre Vulcan. Razvoj se provodi s naglaskom na kori\u0161tenje na stvarnom hardveru \u2014 u po\u010detnoj fazi planira se izrada upravlja\u010dkih programa za ThinkPad, uklju\u010duju\u0107i upravlja\u010dke programe za Intel HD GPU, HD Audio i Intel Gigabit Ethernet. Nakon toga o\u010dekuje se razvoj upravlja\u010dkih programa za AMD GPU i Raspberry Pi plo\u010de. <\/p>\n

Krajnji cilj projekta je stvaranje potpune operativne sustava Ares s vlastitim upraviteljem paketa i grafi\u010dkim korisni\u010dkim su\u010deljem. Kao razlog za stvaranje projekta spominje se sklonost eksperimentiranju i rad kao zabava (princip «just for fun»). Drew DeVault voli postavljati ambiciozne ciljeve i zatim, unato\u010d op\u0107em skepticizmu, ostvarivati ih. Tako je bilo s korisni\u010dkim okru\u017eenjem Sway, email klijentom Aerc, platformom za zajedni\u010dki razvoj SourceHut i programskim jezikom Hare. No, \u010dak i ako novi projekt ne dobije adekvatnu popularnost, poslu\u017eiti \u0107e kao izvor za razvoj novih korisnih sustava. Na primjer, debugger razvijen za Helios planira se prenijeti na Linux platformu, a biblioteke za izgradnju grafi\u010dkog su\u010delja ne\u0107e biti vezane uz platformu.
