Petr Hosek, juhtiv Googles meeskonda, mis vastutab ehituss\u00fcsteemide, kompilaatorite ja arendust\u00f6\u00f6riistade eest, esitles esimest seadet, mis varustatakse Fuchsia operatsioonis\u00fcsteemiga. Fuchsia-p\u00f5hine tarkvara hakkab j\u00f5udma nutikatele fotoraamidele Nest Hub, katsetava v\u00e4rskenduse kaudu Google Preview programmi osalejatele. <\/p>\n

Kui katseperioodi jooksul ei esine etten\u00e4gematuid probleeme, rakendatakse Fuchsia-p\u00f5hist tarkvara ka \u00fclej\u00e4\u00e4nud Nest Hubi seadmetele, mille kasutajad ei m\u00e4rka mingeid erinevusi, kuna Flutteri raamistiku p\u00f5hjal loodud liides j\u00e4\u00e4b samaks, muutes ainult operatsioonis\u00fcsteemi madalama taseme komponente. Varasemates alates 2018. aastast v\u00e4lja antud Google Nest Hub seadmetes, mis kombineerivad fotoraami, meelelahutuss\u00fcsteemi ja nutika kodu juhtimise liidese funktsioone, kasutati Cast'i liidese ja Linuxi tuuma p\u00f5hjal loodud tarkvara. <\/p>\n

Tuletame meelde, et Google'i Fuchsia projekti raames arendatakse alates 2016. aastast mitmekesist operatsioonis\u00fcsteemi, mis suudab t\u00f6\u00f6tada igat t\u00fc\u00fcpi seadmetel, alates t\u00f6\u00f6jaamadest ja nutitelefonidest kuni sisseehitatavate ja tarbijaseadmeteni. Arendust\u00f6\u00f6s on arvesse v\u00f5etud Androidi platvormi loomise kogemust ning p\u00fc\u00fcdmist lahendada skaleeritavuse ja turvalisuse probleeme. <\/p>\n

S\u00fcsteem p\u00f5hineb mikrokeral Zircon, mis on loodud LK projekti arenduste p\u00f5hjal ja mis on laiaulatuslikuks kohandamiseks erinevatesse seadmeklassidesse, sealhulgas nutitelefonidesse ja isiklikesse arvutitesse. Zircon laiendab LK-d, lisades protsesside ja jagatud teekide toe, kasutaja taseme, objektide t\u00f6\u00f6tlemise s\u00fcsteemi ja capability-p\u00f5hise turvalisuse mudeli. Draiverid rakendatakse d\u00fcnaamiliste teekidena, mis t\u00f6\u00f6tavad kasutajaruumi, mida laadib devhost protsess ja haldab seadmehaldur (devmg, Device Manager). <\/p>\n

Fuchsia jaoks on loodud oma graafiline liides, mis on kirjutatud Dart keeles, kasutades Flutter raamistikku. Projektis arendatakse ka kasutajaliidese loomise raamistikku Peridot, pakihaldurit Fargo, standardset raamatukogu libc, renderdus s\u00fcsteemi Escher, Vulkan draiverit Magma, komposiitmanegerit Scenic, failis\u00fcsteeme MinFS, MemFS, ThinFS (FAT Go keeles) ja Blobfs, samuti sektsioonide haldurit FVM. Rakenduste arendamiseks on toetatud keeli C\/C++, Dart, s\u00fcsteemikomponentides on samuti lubatud Rusti kasutamine, v\u00f5rgu stackis Go ja ehituss\u00fcsteemis Python. <\/p>\n

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

Laadimise protsessis kasutatakse s\u00fcsteemihaldurit, mis sisaldab appmgr'i algse programmikeskkonna loomiseks, sysmgr'i laadimis keskkonna kujundamiseks ja basemgr'i kasutajakeskkonna seadistamiseks ning sisselogimise korraldamiseks. Turvalisuse tagamiseks on pakutud t\u00e4iustatud sandbox-isolatsiooni s\u00fcsteem, kus uudsed protsessid ei p\u00e4\u00e4se juurdep\u00e4\u00e4su tuumobjektidele, ei saa eraldada m\u00e4lu ega saata koodi, ning ressurssidele juurdep\u00e4\u00e4suks rakendatakse nimede ruumide s\u00fcsteem, mis m\u00e4\u00e4ratleb k\u00e4ttesaadavad \u00f5igused. Platvorm pakub raamistikku komponentide loomiseks, mis on programmid, mida k\u00e4itatakse oma sandboxes ja mis saavad teiste komponentidega suhelda l\u00e4bi IPC.
