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 kan man k\u00f8re en applikation til ARM p\u00e5 en x86-kompatibel PC. I virtualiseringsmode er kodeudf\u00f8relsens ydeevne i et isoleret milj\u00f8 t\u00e6t p\u00e5 den fysiske systems ydeevne, takket v\u00e6re direkte udf\u00f8relse af instruktioner p\u00e5 CPU'en og brug af 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 Linux-eksekverbare filer bygget til x86-platformen p\u00e5 arkitekturer, der er forskellige fra x86. I l\u00f8bet af udviklingen er der tilf\u00f8jet support til fuld emulator for 14 hardwarearkitekturer, og antallet af emulerede hardwareenheder overstiger 400. Til forberedelse af version 10.0 er der foretaget mere end 2800 \u00e6ndringer fra 211 udviklere.     <\/p>\n<p>N\u00f8gleforbedringer tilf\u00f8jet i QEMU 10.0:   <\/p>\n<ul>\n<li class=\"l\"> I virtio-scsi-driveren, der giver en virtuel SCSI-controller (SCSI Host Bus Adapter) til <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/vps\/\"   title=\"virtual machines\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2201\">virtual machines<\/a>, er der tilf\u00f8jet support til et multik\u00f8-system (multiqueue), der g\u00f8r det muligt at opdele k\u00f8erne for forskellige blokkende enheder for at sikre multitr\u00e5det adgang p\u00e5 multicore-systemer (forskellige k\u00f8er for det samme drev kan behandles af forskellige I\/O-tr\u00e5de). Sammenlignet med driveren for det virtuelle bloksystem (virtio-blk) har den virtuelle SCSI-controller en let forh\u00f8jet ydelse, men tillader brugen af mere end 28 diske.\n<li class=\"l\"> I VFIO (Virtual Function I\/O) er supporten til viderekobling af IGD (Integrated Graphics Device) til integrerede GPU'er, der bruges i 11. (Rocket Lake) og 12. (Alder Lake) generationer af Intel-processorer, forbedret. Supporten for \u00e6ldre GPU'er fra ATI (x550) er blevet tilf\u00f8jet. Grundl\u00e6ggende support for PCI PM (Power Management) er blevet implementeret.\n<li class=\"l\"> Dokumentationen til QMP-protokollen (QEMU Machine Protocol) er blevet betydeligt revideret og udvidet, som giver apps mulighed for at styre QEMU.\n<li class=\"l\"> En ny Live-migrationsfunktion &#171;cpr-transfer&#187; (CheckPoint and Restart) er tilf\u00f8jet, som muligg\u00f8r flytning af g\u00e6stesystemet til en ny QEMU-instans, der k\u00f8rer p\u00e5 den samme v\u00e6rt. Denne tilstand minimerer nedetid ved at spejle g\u00e6stesystemets hukommelse i det virtuelle adressrum af den nye QEMU uden at kopiere indholdet.\n<li class=\"l\"> Grafiske enheder &#8216;apple-gfx-pci&#8217; og &#8216;apple-gfx-mmio&#8217; er tilf\u00f8jet, der bruger rammev\u00e6rket ParavirtualizedGraphics, som er tilg\u00e6ngeligt i macOS, til hardwareaccelereret grafik i g\u00e6stesystemer. Den f\u00f8rste driver er beregnet til brug p\u00e5 x86-64-enheder, mens den anden &#8212; ARM64.\n<li class=\"l\"> I x86-arkitektur-emulatoren er der implementeret support til Intel Xeon Clearwater Forest og Sierra Forest v2 processormodeller. Emuleringen af instruktioner til manipulation af strengdata er blevet accelereret.\n<li class=\"l\"> I ARM-arkitektur-emulatoren er der implementeret support til NPCM8445 Evaluation board og i.MX 8M Plus EVK. Emuleringen af FEAT_AFP, FEAT_RPRES og FEAT_XS samt fysiske og virtuelle EL2-timere er blevet tilf\u00f8jet. Supporten for CPU Arm PXA2xx og emuleringen af iwMMXt-instruktioner er blevet erkl\u00e6ret som for\u00e6ldet.\n<li class=\"l\"> I RISC-V-arkitektur-emulatoren er der implementeret emulering af Microblaze V-kort, CPU Ascalon og CPU RV64 Xiangshan Nanhu. Der er tilf\u00f8jet support for udvidelser af instruktionss\u00e6ttet &#8216;svukte&#8217;, &#8216;ssstateen&#8217;, &#8216;smrnmi&#8217;, &#8216;smdbltrp&#8217; \/ &#8217;ssdbltrp&#8217;, &#8216;supm&#8217;, &#8216;sspm&#8217;, samt tagging af IOMMU-overs\u00e6ttelser og enheder riscv-iommu-sys.\n<li class=\"l\"> I HPPA-arkitektur-emulatoren er der sikret emulering af Diva GSP BMC boards. Firmware SeaBIOS-hppa er blevet opdateret til version 18. Hastigheden af overs\u00e6ttelsen er blevet forbedret. Koden til nulstilling af den virtuelle CPU er forbedret. P\u00e5 64-bit-systemer er der sikret emulering af konfigurationer med op til 256 GB hukommelse.\n<li class=\"l\"> I LoongArch-arkitektur-emulatoren er st\u00f8tte til hot-plugging af CPU'er blevet tilf\u00f8jet. Der er implementeret paravirtualiseret IPI (inter-processor interrupt). Overv\u00e5gning af ventetid for ressourceallokering fra hypervisoren er blevet sikret. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/vps\/abuzoustojchivye-vps\/\"   title=\"KVM\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"4440\">KVM<\/a>Supporten til virtuel routing af eksterne afbrydelser (extioi) er blevet tilf\u00f8jet.\n<li class=\"l\"> I s390x-arkitektur-emulatoren er der tilf\u00f8jet support til 17. generation af mainframe CPU'er og implementeret support til virtio-mem. For at \u00f8ge ydeevnen er muligheden for at interagere med PCI-enheder uden om IOMMU blevet tilf\u00f8jet.    <\/ul>\n<p>Kilde: <a content=\"nofollow\" rel=\"nofollow\"
