Petr Hosek, liderul echipei Google care se ocup\u0103 cu sistemele de compilare, compilatoarele \u0219i instrumentele pentru dezvoltatori, a prezentat primul dispozitiv care va fi echipat cu sistemul de operare Fuchsia. Firmware-ul bazat pe Fuchsia va \u00eencepe s\u0103 fie livrat pe cadrele inteligente pentru fotografii Nest Hub \u00een cadrul unei actualiz\u0103ri experimentale pentru participan\u021bii la programul Google Preview Program. <\/p>\n

Dac\u0103 \u00een timpul implement\u0103rii de test nu vor ap\u0103rea probleme neprev\u0103zute, firmware-ul bazat pe Fuchsia va fi aplicat \u0219i pe dispozitivele altor utilizatori Nest Hub, care nu vor observa diferen\u021be, deoarece interfa\u021ba, construit\u0103 pe baza framework-ului Flutter, va r\u0103m\u00e2ne aceea\u0219i, schimb\u00e2ndu-se doar componentele de baz\u0103 ale sistemului de operare. \u00cen dispozitivele Google Nest Hub lansate din 2018, care combin\u0103 func\u021biile unui cadru pentru fotografii, sistem multimedia \u0219i interfa\u021b\u0103 pentru gestionarea casei inteligente, a fost utilizat firmware-ul pe baza interfe\u021bei Cast \u0219i a nucleului Linux. <\/p>\n

Reamintim c\u0103, \u00een cadrul proiectului Fuchsia, Google dezvolt\u0103 din 2016 un sistem de operare universal, capabil s\u0103 func\u021bioneze pe orice tip de dispozitive, de la sta\u021bii de lucru \u0219i smartphone-uri la tehnologie integrat\u0103 \u0219i consumatoare. Dezvoltarea se realizeaz\u0103 av\u00e2nd \u00een vedere experien\u021ba acumulat\u0103 \u00een crearea platformei Android \u0219i \u021bin\u00e2nd cont de deficien\u021bele \u00een domeniul scal\u0103rii \u0219i asigur\u0103rii securit\u0103\u021bii. <\/p>\n

Sistemul se bazeaz\u0103 pe micro-nucleul Zircon, bazat pe descoperirile proiectului LK, extins pentru a fi utilizat pe diverse clase de dispozitive, inclusiv smartphone-uri \u0219i computere personale. Zircon extinde LK cu suport pentru procese \u0219i biblioteci partajate, nivel de utilizator, sistem de procesare a obiectelor \u0219i un model de asigurare a securit\u0103\u021bii bazat pe capacitate. Driverele sunt implementate sub form\u0103 de biblioteci dinamice care func\u021bioneaz\u0103 \u00een spa\u021biul utilizatorului, \u00eenc\u0103rcate de procesul devhost \u0219i gestionate de managerul de dispozitive (devmg, Device Manager). <\/p>\n

Pentru Fuchsia, o interfa\u021b\u0103 grafic\u0103 proprie, scris\u0103 \u00een Dart folosind cadrul Flutter, a fost preg\u0103tit\u0103. Proiectul dezvolt\u0103 de asemenea cadrul pentru construirea interfe\u021belor utilizatorului Peridot, managerul de pachete Fargo, biblioteca standard libc, sistemul de redare Escher, driverul Vulkan Magma, managerul de compunere Scenic, sistemele de fi\u0219iere MinFS, MemFS, ThinFS (FAT \u00een Go) \u0219i Blobfs, precum \u0219i managerul de parti\u021bii FVM. Pentru dezvoltarea aplica\u021biilor, suport pentru limbajele C\/C++, Dart este oferit, iar \u00een componentele de sistem se poate utiliza \u0219i Rust, \u00een stiva de re\u021bea Go \u0219i \u00een sistemul de constru\u021bie limbajul Python. <\/p>\n

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

\u00cen procesul de \u00eenc\u0103rcare, se utilizeaz\u0103 un manager de sistem care include appmgr pentru a crea un mediu ini\u021bial de programare, sysmgr pentru a forma un mediu de \u00eenc\u0103rcare \u0219i basemgr pentru configurarea unui mediu utilizator \u0219i organizarea autentific\u0103rii. Pentru a asigura securitatea, se propune un sistem avansat de izolare sandbox, \u00een care noile procese nu au acces la obiectele nucleului, nu pot aloca memorie \u0219i nu pot rula cod, iar accesul la resurse se realizeaz\u0103 printr-un sistem de namespace-uri, definind permisiunile disponibile. Platforma ofer\u0103 un cadru pentru crearea de componente care reprezint\u0103 programe ce ruleaz\u0103 \u00een sandbox-ul propriu, care pot interac\u021biona cu alte componente prin IPC.
