Fuchsia-OS har v\u00e6ret under udvikling af Google siden 2016 med fokus p\u00e5 mangler i skalerbarhed og sikkerhed, der findes i Android-platformen.     <\/p>\n<p>De vigtigste \u00e6ndringer i Fuchsia 14:  <\/p>\n<ul>\n<li class=\"l\"> Mulighederne for Starnix-laget er udvidet, hvilket muligg\u00f8r k\u00f8rsel af u\u00e6ndrede Linux-programmer ved at overs\u00e6tte system-API'erne fra Linux-kernen til de tilsvarende Fuchsia-undersystemer. Den nye version har tilf\u00f8jet support til montering af fjernede filsystemer, xattrs for symbolske links er omfattet i fxfs, sporing er tilf\u00f8jet til systemkaldet mmap(), der er tilf\u00f8jet udvidet information i \/proc\/pid\/stat, support for fuchsia_sync::Mutex er inkluderet, O_TMPFILE, pidfd_getfd, sys_reboot(), timer_create, timer_delete, times() og ptrace() er underst\u00f8ttet, og den systemfil-cache, der anvendes i implementeringen af ext4, er blevet aktiveret.\n<li class=\"l\"> Bluetooth-stakken er forbedret. Der er tilf\u00f8jet st\u00f8tte til lyd i Bluetooth-profilen HSP (HandSet Profile), og forsinkelser ved streaming af lyd via A2DP-profilen er reduceret.\n<li class=\"l\"> I Matter, implementeringen af standarden for tilslutning af enheder i smart home, er der tilf\u00f8jet st\u00f8tte for gruppeopdatering og mulighed for at h\u00e5ndtere overgangstilstande ved styring af belysning.\n<li class=\"l\"> I netv\u00e6rksstakken for alle platforme er der tilf\u00f8jet st\u00f8tte til FastUDP-sockets.\n<li class=\"l\"> Der er tilf\u00f8jet support til flerkernede systemer (SMP) baseret p\u00e5 RISC-V-arkitekturen.\n<li class=\"l\"> Der er tilf\u00f8jet et API til interaktion med opgavestyreren.\n<li class=\"l\"> Support til DeviceTree er tilf\u00f8jet.\n<li class=\"l\"> Driveren til lydenheder med USB-interface er blevet konverteret til at bruge DFv2-rammen.          <\/ul>\n<p>Fuchsia er baseret p\u00e5 mikrokerne Zircon, der bygger videre p\u00e5 LK-projektets arbejde, udvidet til at bruges p\u00e5 forskellige typer enheder, herunder smartphones og personlige computere. Zircon udvider LK med st\u00f8tte til processer og delte biblioteker, brugerlaget, objektbehandlingssystemet og en security model baseret p\u00e5 capability. Drivere implementeres som dynamiske biblioteker, der k\u00f8rer i brugerrummet, indl\u00e6st af devhost-processen og styret af enhedsadministrator (devmg, Device Manager).    <\/p>\n<p>Fuchsia har f\u00e5et en egen grafisk brugergr\u00e6nseflade, der er skrevet i Dart ved hj\u00e6lp af Flutter-rammev\u00e6rket. Projektet udvikler ogs\u00e5 et rammev\u00e6rk til opbygning af brugergr\u00e6nseflader kaldet Peridot, pakkeh\u00e5ndteringssystemet Fargo, standardbiblioteket libc, renderingssystemet Escher, Vulkan-driveren Magma, sammens\u00e6tningmanageren Scenic, filsystemerne MinFS, MemFS, ThinFS (FAT p\u00e5 Go) og Blobfs samt partitionsmanageren FVM. Der tilbydes support for programmeringssprog som C\/C++, Dart, og i systemkomponenterne er brugen af Rust tilladt, mens Go anvendes i netv\u00e6rksstakken og Python i byggesystemet.    <\/p>\n<p>Under opstarten anvendes en systemmanager, der omfatter appmgr til at skabe det indledende programmilj\u00f8, sysmgr til at lave opstartsmilj\u00f8et og basemgr til at konfigurere bruger milj\u00f8et og organisere loginprocessen. For at sikre sikkerheden tilbydes et avanceret sandbox-isoleringssystem, hvor nye processer ikke har adgang til kerneobjekter, ikke kan allokere hukommelse og ikke kan k\u00f8re kode, og adgangen til ressourcer reguleres af et navnerumssystem, der definerer de tilg\u00e6ngelige bef\u00f8jelser. Platformen leverer et rammev\u00e6rk til oprettelse af komponenter, som er programmer, der k\u00f8rer i deres egen sandbox, og som kan interagere med andre komponenter via IPC.<br \/>\n<br \/>Kilde:
