Firma Google rozpocz\u0119\u0142a wdra\u017canie nowego oprogramowania opartego na systemie Fuchsia dla inteligentnych ram elektronicznych Nest Hub Max, produkowanych od 2019 roku. Na pocz\u0105tkowym etapie oprogramowanie oparte na Fuchsia zacznie by\u0107 dostarczane uczestnikom programu Google Preview Program, a je\u015bli w trakcie test\u00f3w nie wyst\u0105pi\u0105 nieprzewidziane problemy, oprogramowanie zostanie zastosowane tak\u017ce na urz\u0105dzeniach innych u\u017cytkownik\u00f3w Nest Hub Max. <\/p>\n

Ramka Nest Hub Max sta\u0142a si\u0119 drugim urz\u0105dzeniem konsumenckim, kt\u00f3re zosta\u0142o wyposa\u017cone w system operacyjny Fuchsia. Pierwszym urz\u0105dzeniem, kt\u00f3re otrzyma\u0142o oprogramowanie oparte na Fuchsia rok temu, by\u0142 model Nest Hub, kt\u00f3ry r\u00f3\u017cni si\u0119 mniejszym ekranem i brakiem wbudowanej kamery, wykorzystywanej w systemie monitorowania i zapewnienia bezpiecze\u0144stwa. Pomimo zmiany systemu operacyjnego w oprogramowaniu, interfejs u\u017cytkownika i funkcjonalno\u015b\u0107 zosta\u0142y w pe\u0142ni zachowane, a u\u017cytkownicy ko\u0144cowi nie powinni zauwa\u017cy\u0107 r\u00f3\u017cnic, poniewa\u017c interfejs oparty jest na frameworku Flutter i jest abstrakcyjny wzgl\u0119dem komponent\u00f3w niskiego poziomu. Wcze\u015bniej w urz\u0105dzeniach Nest Hub Max, \u0142\u0105cz\u0105cych funkcje ramki do zdj\u0119\u0107, systemu multimedialnego oraz interfejsu do zarz\u0105dzania inteligentnym domem, stosowano oprogramowanie oparte na pow\u0142oce Cast i j\u0105drze Linux. <\/p>\n

System operacyjny Fuchsia rozwija si\u0119 w firmie Google od 2016 roku, maj\u0105c na uwadze niedoskona\u0142o\u015bci w zakresie skalowalno\u015bci i bezpiecze\u0144stwa, kt\u00f3re wyst\u0119puj\u0105 w platformie Android. System oparty jest na mikroj\u0105drze Zircon, kt\u00f3re powsta\u0142o na bazie projektu LK, rozszerzonego do wykorzystania w r\u00f3\u017cnych klasach urz\u0105dze\u0144, w tym smartfonach i komputerach osobistych. Zircon rozszerza LK o wsparcie dla proces\u00f3w i bibliotek wsp\u00f3\u0142dzielonych, poziom u\u017cytkownika, system przetwarzania obiekt\u00f3w oraz model zapewnienia bezpiecze\u0144stwa oparty na capability. Sterowniki s\u0105 realizowane w postaci dynamicznych bibliotek dzia\u0142aj\u0105cych w przestrzeni u\u017cytkownika, \u0142adowanych przez proces devhost i zarz\u0105dzanych przez mened\u017cera urz\u0105dze\u0144 (devmg, Device Manager). <\/p>\n

Dla Fuchsia przygotowano w\u0142asny interfejs graficzny napisany w j\u0119zyku Dart z u\u017cyciem frameworka Flutter. Projekt rozwija r\u00f3wnie\u017c framework do budowy interfejs\u00f3w u\u017cytkownika Peridot, mened\u017cer pakiet\u00f3w Fargo, standardow\u0105 bibliotek\u0119 libc, system renderowania Escher, sterownik Vulkan Magma, mened\u017cer kompozycji Scenic, systemy plik\u00f3w MinFS, MemFS, ThinFS (FAT w j\u0119zyku Go) i Blobfs oraz mened\u017cer partycji FVM. Dla rozwoju aplikacji udost\u0119pniona jest obs\u0142uga j\u0119zyk\u00f3w C\/C++, Dart, w komponentach systemowych mo\u017cliwe jest tak\u017ce u\u017cycie Rust, w stosie sieciowym Go, a w systemie budowy j\u0119zyka Python. <\/p>\n

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

W trakcie \u0142adowania u\u017cywany jest mened\u017cer systemu, kt\u00f3ry obejmuje appmgr do stworzenia pocz\u0105tkowego \u015brodowiska programowego, sysmgr do formowania \u015brodowiska \u0142adowania oraz basemgr do konfiguracji \u015brodowiska u\u017cytkownika i organizacji logowania do systemu. Aby zapewni\u0107 bezpiecze\u0144stwo, wprowadzono zaawansowany system izolacji sandbox, w kt\u00f3rym nowe procesy nie maj\u0105 dost\u0119pu do obiekt\u00f3w j\u0105dra, nie mog\u0105 przydziela\u0107 pami\u0119ci i nie mog\u0105 uruchamia\u0107 kodu, a dost\u0119p do zasob\u00f3w realizowany jest przez system przestrzeni nazw, kt\u00f3ry okre\u015bla dost\u0119pne uprawnienia. Platforma udost\u0119pnia framework do tworzenia komponent\u00f3w, kt\u00f3re s\u0105 programami uruchamianymi w swoim sandboksie, kt\u00f3re mog\u0105 komunikowa\u0107 si\u0119 z innymi komponentami poprzez IPC.
