O Fuchsia est\u00e1 sendo desenvolvido pela Google desde 2016, levando em conta as falhas em escalabilidade e seguran\u00e7a da plataforma Android.     <\/p>\n<p>Principais mudan\u00e7as no Fuchsia 14:  <\/p>\n<ul>\n<li class=\"l\"> As capacidades da camada Starnix foram ampliadas, permitindo a execu\u00e7\u00e3o de programas Linux n\u00e3o modificados atrav\u00e9s da tradu\u00e7\u00e3o das interfaces de sistema do n\u00facleo Linux para as chamadas das subsistemas correspondentes do Fuchsia. A nova vers\u00e3o adicionou suporte ao montagem de sistemas de arquivos remotos, adicionou xattrs para links simb\u00f3licos no fxfs, incluiu pontos de rastreamento na chamada de sistema mmap(), ampliou as informa\u00e7\u00f5es em \/proc\/pid\/stat, incluiu suporte a fuchsia_sync::Mutex, implementou suporte a O_TMPFILE, pidfd_getfd, sys_reboot(), timer_create, timer_delete, times() e ptrace(), e realizou o uso do cache de arquivo do sistema na implementa\u00e7\u00e3o do ext4.\n<li class=\"l\"> A pilha Bluetooth foi aprimorada. Suporte ao \u00e1udio no perfil Bluetooth HSP (HandSet Profile) foi adicionado e os atrasos na transmiss\u00e3o de \u00e1udio atrav\u00e9s do perfil A2DP foram reduzidos.\n<li class=\"l\"> No Matter, a implementa\u00e7\u00e3o do padr\u00e3o para conectar dispositivos em casas inteligentes, foi adicionado o suporte para grupos de atualiza\u00e7\u00e3o e a capacidade de lidar com estados de transi\u00e7\u00e3o ao gerenciar a ilumina\u00e7\u00e3o.\n<li class=\"l\"> O suporte a sockets FastUDP foi inclu\u00eddo na pilha de rede para todas as plataformas.\n<li class=\"l\"> O suporte a sistemas multicores (SMP) com arquitetura RISC-V foi adicionado.\n<li class=\"l\"> Uma API foi adicionada para intera\u00e7\u00e3o com o planejador de tarefas.\n<li class=\"l\"> O suporte ao DeviceTree foi adicionado.\n<li class=\"l\"> O driver para dispositivos de som com interface USB foi migrado para o uso da estrutura DFv2.          <\/ul>\n<p>O Fuchsia \u00e9 baseado no microkernel Zircon, que se baseia nos desenvolvimentos do projeto LK, ampliado para uso em v\u00e1rias classes de dispositivos, incluindo smartphones e computadores pessoais. O Zircon expande o LK com suporte a processos e bibliotecas compartilhadas, n\u00edvel de usu\u00e1rio, sistema de gerenciamento de objetos e modelo de seguran\u00e7a baseado em capabilities. Os drivers s\u00e3o implementados como bibliotecas din\u00e2micas que operam no espa\u00e7o do usu\u00e1rio, carregadas pelo processo devhost e gerenciadas pelo gerenciador de dispositivos (devmg, Device Manager).    <\/p>\n<p>Para o Fuchsia, foi desenvolvido uma interface gr\u00e1fica pr\u00f3pria, escrita na linguagem Dart usando o framework Flutter. O projeto tamb\u00e9m desenvolve o framework Peridot para a cria\u00e7\u00e3o de interfaces de usu\u00e1rio, o gerenciador de pacotes Fargo, a biblioteca padr\u00e3o libc, o sistema de renderiza\u00e7\u00e3o Escher, o driver Vulkan Magma, o gerenciador de composi\u00e7\u00e3o Scenic, os sistemas de arquivos MinFS, MemFS, ThinFS (FAT na linguagem Go) e Blobfs, assim como o gerenciador de parti\u00e7\u00f5es FVM. Para o desenvolvimento de aplicativos, h\u00e1 suporte para as linguagens C\/C++, Dart, e nos componentes do sistema tamb\u00e9m \u00e9 permitido o uso de Rust, no stack de rede Go, e no sistema de constru\u00e7\u00e3o da linguagem Python.    <\/p>\n<p>Durante o processo de inicializa\u00e7\u00e3o, utiliza-se um gerenciador de sistema, que inclui o appmgr para criar o ambiente de programa inicial, sysmgr para configurar o ambiente de inicializa\u00e7\u00e3o e basemgr para definir o ambiente do usu\u00e1rio e organizar o login no sistema. Para garantir a seguran\u00e7a, \u00e9 oferecido um avan\u00e7ado sistema de isolamento sandbox, onde novos processos n\u00e3o t\u00eam acesso aos objetos do kernel, n\u00e3o podem alocar mem\u00f3ria e n\u00e3o podem executar c\u00f3digo, e para acesso a recursos \u00e9 aplicada uma sistema de espa\u00e7os de nome, determinando as permiss\u00f5es dispon\u00edveis. A plataforma fornece um framework para a cria\u00e7\u00e3o de componentes, que s\u00e3o programas que s\u00e3o executados em seu pr\u00f3prio sandbox e podem interagir uns com os outros atrav\u00e9s de IPC.<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=60221\">opennet.ru<\/a>
