Som emulator g\u00f8r QEMU det muligt at k\u00f8re programmer, der er bygget til \u00e9n hardwareplatform, p\u00e5 et system med en helt anden arkitektur, for eksempel at k\u00f8re en applikation til ARM p\u00e5 en x86-kompatibel pc. I virtualiseringstilstand er kodeudf\u00f8relsens ydeevne i et isoleret milj\u00f8 t\u00e6t p\u00e5 den af den fysiske system takket v\u00e6re direkte udf\u00f8relse af instruktioner p\u00e5 CPU'en og ved at involvere hypervisoren Xen eller KVM-modulet i Linux, eller NVMM-modulet i NetBSD.    <\/p>\n<p>Projektet blev oprindeligt skabt af Fabrice Bellard med det form\u00e5l at muligg\u00f8re k\u00f8rsel af eksekverbare filer fra Linux, der er bygget til x86-platformen, p\u00e5 arkitekturer, der adskiller sig fra x86. Gennem \u00e5rene er der blevet tilf\u00f8jet st\u00f8tte til fuld emulering for 14 hardwarearkitekturer, og antallet af emulerede hardwareenheder har overskredet 400. I forberedelsen af version 10.2.0 er over 2200 \u00e6ndringer blevet implementeret af 188 udviklere.     <\/p>\n<p>N\u00f8gleforbedringer tilf\u00f8jet i QEMU 10.2:   <\/p>\n<ul>\n<li class=\"l\"> I backend 9pfs, der muligg\u00f8r brug af Plan 9 netv\u00e6rksfilsystem til adgang mellem virtuelle maskiner, er der tilf\u00f8jet underst\u00f8ttelse af FreeBSD.\n<li class=\"l\"> Der er tilf\u00f8jet en ny Live-migrationsmode &#8216;cpr-exec&#8217;, der reducerer ressourceforbruget under opdateringer. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/vps\/\"   title=\"virtual machines\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2251\">virtual machines<\/a> og potentielt genbruge eksisterende tilstande og forbindelser ved opdatering.\n<li class=\"l\"> Hovedbegivenhedscyklussen i QEMU er blevet \u00e6ndret til at bruge io_uring gr\u00e6nsefladen til asynkron input\/output p\u00e5 systemer, der underst\u00f8tter det, hvilket resulterer i \u00f8get ydeevne.\n<li class=\"l\"> Emuleringen i user-mode er blevet forbedret, hvilket muligg\u00f8r k\u00f8rsel af separate processer, der er bygget til en anden CPU. Systemopkaldet fchmodat2 er implementeret, der er tilf\u00f8jet st\u00f8tte til flagene MADV_DONTDUMP og MADV_DODUMP, og underst\u00f8ttelsen af arkitekturerne aarch64, hppa og microblaze er forbedret.\n<li class=\"l\"> Emulatoren for ARM-arkitektur har f\u00e5et support til modellen amd-versal2-virt, der implementerer AMD Versal virtuelle SoC. Underst\u00f8ttelsen af bundkortene &#8216;AST2600&#8217;, &#8216;AST2700&#8217;, &#8216;AST1030&#8217; og &#8216;xlnx-zynqmp&#8217; er forbedret. Emuleringen af CPU-udvidelserne FEAT_SCTLR2, FEAT_TCR2, FEAT_CSSC, FEAT_LSE128, FEAT_ATS1A, FEAT_RME_GPC2, FEAT_AIE, FEAT_MEC og FEAT_GCS er blevet realiseret.\n<li class=\"l\"> I HPPA-arkitektur emulatoren er der tilf\u00f8jet mulighed for at emulere HP 715\/64 workstation, SCSI-controlleren NCR 53c710 og HP LASI input\/output-controlleren.\n<li class=\"l\"> Emulatoren til PowerPC-arkitektur har tilf\u00f8jet support for PowerNV11 og PPE42 CPU'er. For pSeries-udstyr er der implementeret en FADUMP-mekanisme (Firmware-Assisted Dump) til at oprette systemtilstands-dump efter et systemfejl.\n<li class=\"l\"> I emulatoren til RISC-V-arkitektur er API MonitorDef HMP implementeret, OpenSBI (Open Supervisor Binary Interface) er opdateret til version 1.7, og der er foretaget en stor m\u00e6ngde fejlrettelser.\n<li class=\"l\"> I emulatoren til s390x-arkitektur er virtio-pci blevet optimeret ved hj\u00e6lp af teknologien til virtuel interrupt substitution ved hj\u00e6lp af irqfd for at forbedre ydeevnen.        <\/ul>\n<p>Kilde: <a
