Petr Hosek, koji vodi tim u Googleu odgovoran za sustave gradnje, kompajlere i alate za programere, predstavio je ure\u0111aj koji \u0107e dolaziti s operativnim sustavom Fuchsia. Firmware temeljen na Fuchsii po\u010det \u0107e se isporu\u010divati u pametne okvire za fotografije Nest Hub kao dio eksperimentalne nadogradnje za sudionike Google Preview Program. <\/p>\n

Ako tijekom probnog implementiranja ne do\u0111e do nepredvi\u0111enih problema, firmware temeljen na Fuchsii bit \u0107e primijenjen i na ure\u0111aje ostalih korisnika Nest Hub-a, koji ne\u0107e primijetiti razlike jer \u0107e su\u010delje, izgra\u0111eno na temelju Flutter frameworka, ostati isto, a promijenit \u0107e se samo niskorazinski sastav operativnog sustava. Ranije je na ure\u0111ajima Google Nest Hub, koji od 2018. godine kombiniraju funkcije okvira za fotografije, multimedijske sustave i su\u010delja za upravljanje pametnim domom, kori\u0161ten firmware temeljen na Shell Cast i Linux kernelu. <\/p>\n

Podsje\u0107amo da se u okviru projekta Fuchsia Google razvija univerzalni operativni sustav od 2016. godine, sposoban raditi na svim vrstama ure\u0111aja, od radnih stanica i pametnih telefona do ugra\u0111ene i potro\u0161a\u010dke opreme. Razvoj se provodi uzimaju\u0107i u obzir iskustvo iz stvaranja platforme Android i uzimaju\u0107i u obzir nedostatke u podru\u010dju skaliranja i sigurnosti. <\/p>\n

Sustav se temelji na mikrojezgri Zircon, koja se oslanja na radove projekta LK, pro\u0161irena za kori\u0161tenje na razli\u010ditim klasama ure\u0111aja, uklju\u010duju\u0107i pametne telefone i osobne ra\u010dunala. Zircon pro\u0161iruje LK podr\u0161kom za procese i dijeljene biblioteke, korisni\u010dkim razinama, sustavima obrade objekata i modelom sigurnosti temeljenim na capability. Upravlja\u010dki programi se implementiraju u obliku dinami\u010dkih knji\u017enica koje rade u korisni\u010dkom prostoru, u\u010ditavaju ih proces devhost i njima upravlja upravitelj ure\u0111aja (devmg, Device Manager). <\/p>\n

Za Fuchsia je razvijen vlastiti grafi\u010dki su\u010delje, napisano u jeziku Dart koriste\u0107i framework Flutter. Projekt tako\u0111er razvija framework za izradu korisni\u010dkih su\u010delja Peridot, paketni upravitelj Fargo, standardnu biblioteku libc, sustav za prikazivanje Escher, Vulkan voza\u010d Magma, upravitelj sastavljanja Scenic, datote\u010dne sustave MinFS, MemFS, ThinFS (FAT na jeziku Go) i Blobfs, kao i upravitelj particija FVM. Za razvoj aplikacija podr\u017eani su jezici C\/C++, Dart, dok se u sistemskim komponentama tako\u0111er mo\u017ee koristiti Rust, u mre\u017enom sloju Go, a u sustavu gradnje jezika Python. <\/p>\n

\"Google<\/center> <\/p>\n

U procesu pokretanja koristi se sistemski upravitelj koji uklju\u010duje appmgr za kreiranje inicijalnog programskog okru\u017eenja, sysmgr za formiranje pokretnog okru\u017eenja i basemgr za konfiguraciju korisni\u010dkog okru\u017eenja i organizaciju prijave u sustav. Za osiguranje sigurnosti predvi\u0111ena je napredna sistemska sandbox-izolacija, u kojoj novi procesi nemaju pristup objektima jezgre, ne mogu dodjeljivati memoriju i ne mogu izvr\u0161avati kod, dok se za pristup resursima koristi sustav imenskih prostora koji odre\u0111uje dostupna ovla\u0161tenja. Platforma pru\u017ea framework za izradu komponenti, koje su programi koji se izvr\u0161avaju u svom sandboxu i mogu komunicirati s drugim komponentama putem IPC.
