Compania Google a \u00eenceput s\u0103 distribuie un nou firmware bazat pe sistemul de operare Fuchsia pentru rame foto inteligente Nest Hub Max, lansate din 2019. \u00cen prima etap\u0103, firmware-ul bazat pe Fuchsia va fi livrat participan\u021bilor din programul Google Preview Program, iar dac\u0103 \u00een timpul implement\u0103rii de testare nu apar probleme neprev\u0103zute, firmware-ul va fi aplicat \u0219i pe dispozitivele altor utilizatori Nest Hub Max. <\/p>\n

Rama foto Nest Hub Max a devenit al doilea dispozitiv de consum echipat cu sistemul de operare Fuchsia. Prima actualizare bazat\u0103 pe Fuchsia a fost primit\u0103 acum un an de modelul Nest Hub, care are un ecran mai mic \u0219i nu dispune de camer\u0103 video \u00eencorporat\u0103, utilizat\u0103 \u00een sistemul de supraveghere \u0219i asigurare a securit\u0103\u021bii. \u00cen ciuda \u00eenlocuirii sistemului de operare \u00een firmware, interfa\u021ba utilizator \u0219i func\u021bionalitatea r\u0103m\u00e2n complet intacte, iar utilizatorii finali nu ar trebui s\u0103 observe diferen\u021be, deoarece interfa\u021ba este construit\u0103 pe baza framework-ului Flutter \u0219i este abstractizat\u0103 de componentele de nivel inferior. Anterior, dispozitivele Nest Hub Max, care combin\u0103 func\u021bii de ram\u0103 foto, sistem multimedia \u0219i interfa\u021b\u0103 pentru controlul casei inteligente, utilizau un firmware bazat pe shell-ul Cast \u0219i kernel-ul Linux. <\/p>\n

Sistemul de operare Fuchsia este dezvoltat de Google din 2016, av\u00e2nd \u00een vedere deficien\u021bele \u00een scalabilitate \u0219i securitate existente \u00een platforma Android. Sistemul se bazeaz\u0103 pe microkernel-ul Zircon, bazat pe lucr\u0103rile proiectului LK, extins pentru a fi utilizat pe diverse clase de dispozitive, inclusiv smartphone-uri \u0219i calculatoare personale. Zircon extinde LK prin suport pentru procese \u0219i biblioteci partajate, un nivel de utilizator, un sistem de gestionare a obiectelor \u0219i un model de securitate bazat pe capacit\u0103\u021bi. Driverele sunt implementate sub form\u0103 de biblioteci dinamice care ruleaz\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.
