Som en emulator gj\u00f8r QEMU det mulig \u00e5 kj\u00f8re et program bygget for en maskinvareplattform p\u00e5 et system med en helt annen arkitektur, for eksempel \u00e5 kj\u00f8re en applikasjon for ARM p\u00e5 en x86-kompatibel PC. I virtualiseringsmodus er ytelsen til kodekj\u00f8ring i et isolert milj\u00f8 n\u00e6r den fysiske systemytelsen takket v\u00e6re direkte kj\u00f8ring av instruksjoner p\u00e5 CPU og bruk av hypervisoren Xen eller KVM-modulen.       <\/p>\n<p>Opprinnelig ble prosjektet opprettet av Fabrice Bellard for \u00e5 muliggj\u00f8re kj\u00f8ring av utf\u00f8rbare filer bygget for x86-plattformen p\u00e5 arkitekturer som ikke er x86. Gjennom \u00e5rene har prosjektet f\u00e5tt st\u00f8tte for full emulering for 14 maskinvarearkitekturer, og antallet emulerte maskinvareenheter har oversteget 400. I utviklingen av versjon 7.2 er det gjort mer enn 1800 endringer av 205 utviklere.     <\/p>\n<p>N\u00f8kkelforbedringer lagt til QEMU 7.2:   <\/p>\n<ul>\n<li class=\"l\"> I emulatoren for x86-arkitekturen er det lagt til st\u00f8tte for AVX, AVX2, F16C, FMA3 og VAES-instruksjoner i den klassiske TCG-kodegeneratoren, samt ytelsesoptimalisering relatert til bruk av SSE-instruksjoner. For <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/no\/vps\/abuzoustojchivye-vps\/\"   title=\"KVM\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"4417\">KVM<\/a> st\u00f8tte for mekanismen for overv\u00e5king av utgang fra den virtuelle maskinen (\u00bbnotify vmexit\u00ab) er lagt til, noe som gj\u00f8r det mulig \u00e5 omg\u00e5 feil i CPU som kan f\u00f8re til hang.\n<li class=\"l\"> I ARM-emulatoren er st\u00f8tten for CPU Cortex-A35 og prosessorutvidelsene ETS (Enhanced Translation Synchronization), PMUv3p5 (PMU Extensions 3.5), GTG (Guest Translation Granule 4KB, 16KB, 64KB), HAFDBS (maskinvarekontroll av tilgangsflagg og Status \u00abdirty\u00bb) og E0PD (forhindring av tilgang EL0 til delte adresser) implementert.\n<li class=\"l\"> I LoongArch-emulatoren er det lagt til st\u00f8tte for fw_cfg DMA, hotplugging av minne og emulering av TPM-enheter (Trusted Platform Module).\n<li class=\"l\"> I OpenRISC-arkitekturens emulator er plattformen \u2018virt\u2019 for enhetstesting og kontinuerlig integrasjon implementert. St\u00f8tte for flertr\u00e5det utf\u00f8relse av den klassiske koden TCG (Tiny Code Generator) er ogs\u00e5 implementert.\n<li class=\"l\"> I RISC-V-arkitekturens emulator i de emulerte \u2018virt\u2019-maskinene er muligheten for \u00e5 laste inn fastvare fra pflash i S-modus (S-mode) implementert. Arbeidet med enhetstre er forbedret.\n<li class=\"l\"> I emulatoren av arkitekturen 390x er det lagt til st\u00f8tte for MSA5-utvidelsen (Message-Security-Assist Extension 5 med PRNO-instruksjon for generering av pseudo-tilfeldige tall), instruksjonene KIMD\/KLM (SHA-512 implementering) og utvidet zPCI-tolkning for gjesteoperativsystemer basert p\u00e5 KVM-hypervisoren.\n<li class=\"l\"> I backendene for minneh\u00e5ndtering er det implementert forh\u00e5ndsallokering av minne med hensyn til NUMA-arkitekturen.\n<li class=\"l\"> Sikkerhetskontrollen av krypterte blokkeringsenheter LUKS er forbedret, og det er lagt til mulighet for \u00e5 opprette LUKS-bilder i macOS.\n<li class=\"l\"> I 9pfs-backend, som gj\u00f8r det mulig \u00e5 bruke Plan 9 nettverksfilssystem for tilgang fra en virtuell maskin til en annen, har overgangen til \u00e5 bruke GHashTable som hash i identitetstabellen f\u00f8rt til \u00f8kt ytelse p\u00e5 6-12 ganger i noen situasjoner.\n<li class=\"l\"> Nye netdev-backends stream og dgram er lagt til.\n<li class=\"l\"> I agenten for gjestesystemer basert p\u00e5 ARM-arkitekturen er st\u00f8tte for FreeBSD lagt til.\n<li class=\"l\"> I GUI-byggene for macOS er det n\u00e5 mulig \u00e5 inkludere grensesnitt basert p\u00e5 Cocoa og SDL\/GTK i \u00e9n kj\u00f8rbar fil.\n<li class=\"l\"> Den innebygde undermodulen \u00abslirp\u00bb er fjernet, og det anbefales \u00e5 bruke det systembiblioteket libslirp i stedet.\n<li class=\"l\"> P\u00e5 grunn av manglende testmuligheter er st\u00f8tten for verts-systemer med 32-bits MIPS-prosessorer som bruker \u2018Big endian\u2019-byte-rekkef\u00f8lge utd\u00f8dd.    <\/ul>\n<p>Kilde: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=58327\">opennet.ru<\/a>
