Kot emulator QEMU omogo\u010da zagon programa, zgrajenega za eno strojno platformo, na sistemu z povsem druga\u010dno arhitekturo, na primer, izvajanje aplikacije za ARM na PC-ju, zdru\u017eljivim s x86. V na\u010dinu virtualizacije v QEMU je hitrost izvajanja kode v izoliranem okolju blizu strojni zmogljivosti zaradi neposrednega izvajanja ukazov na CPU-ju in uporabe hipervizorja Xen ali modula KVM v Linuxu, ali modula NVMM v NetBSD.    <\/p>\n<p>Projekt je prvotno ustvaril Fabrice Bellard z namenom, da bi omogo\u010dil zagon izvr\u0161nih datotek Linux, zgrajenih za platformo x86, na arhitekturah, ki so druga\u010dne od x86. Med razvojem so dodali podporo za popolno emulacijo za 14 strojnih arhitektur, \u0161tevilo emuliranih strojnih naprav pa je preseglo 400. Za razli\u010dico 10.0 je bilo izvedenih ve\u010d kot 2800 sprememb s strani 211 razvijalcev.     <\/p>\n<p>Klju\u010dne izbolj\u0161ave, dodane v QEMU 10.0:   <\/p>\n<ul>\n<li class=\"l\"> V gonilniku virtio-scsi, ki zagotavlja virtualni SCSI kontroler (SCSI Host Bus Adapter) za <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/sl\/vps\/\"   title=\"virtualnih naprav\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2201\">virtualnih naprav<\/a>, je bila dodana podpora za ve\u010dstopenjski sistem \u010dakalnih vrst (multiqueue), ki omogo\u010da razdelitev \u010dakalnih vrst za razli\u010dne blokovne naprave za zagotavljanje ve\u010dprocesorskega dostopa na ve\u010djedrnih sistemih (razli\u010dne \u010dakalne vrste za enega diska lahko obdelujejo razli\u010dni I\/O tokovi). V primerjavi z gonilnikom virtualne blok naprave (virtio-blk) virtualni SCSI kontroler nekoliko zaostaja po zmogljivosti, vendar omogo\u010da uporabo ve\u010d kot 28 diskov.\n<li class=\"l\"> V VFIO (Virtual Function I\/O) je bila izbolj\u0161ana podpora za preusmeritev IGD (Integrated Graphics Device) za integrirane GPU-je, uporabljene v 11 (Rocket Lake) in 12 (Alder Lake) generacijah procesorjev Intel. Dodana je bila podpora za stare GPU-je ATI (x550). Uvedena je osnovna podpora za PCI PM (Power Management).\n<li class=\"l\"> Dokumentacija za protokol QMP (QEMU Machine Protocol) je bila bistveno predelana in raz\u0161irjena, kar omogo\u010da aplikacijam upravljanje z QEMU.\n<li class=\"l\"> Dodana je nova funkcija Live-migracije &#171;cpr-transfer&#187; (CheckPoint and Restart), ki omogo\u010da premik gostiteljske naprave v nov instan\u010dno QEMU, ki deluje na istem gostitelju. Ta na\u010din minimizira \u010das zaustavitve, saj se pomnilnik gostiteljske naprave odra\u017ea v virtualnem naslovnem prostoru novega QEMU brez kopiranja vsebine.\n<li class=\"l\"> Dodane so grafi\u010dne naprave &#8216;apple-gfx-pci&#8217; in &#8216;apple-gfx-mmio&#8217;, ki uporabljajo ogrodje ParavirtualizedGraphics, ki ga nudi macOS za strojno pospe\u0161evanje grafike v gostiteljskih sistemih. Prvi gonilnik je namenjen uporabi na napravah x86-64, drugi pa na ARM64.\n<li class=\"l\"> V emulatorju arhitekture x86 je bila uvedena podpora za modele procesorjev Intel Xeon Clearwater Forest in Sierra Forest v2. Pospe\u0161ena je emulacija ukazov za manipulacijo s podatkovnimi nizi.\n<li class=\"l\"> V emulatorju arhitekture ARM je bila uvedena podpora za plo\u0161\u010de NPCM8445 Evaluation in i.MX 8M Plus EVK. Dodana je emulacija raz\u0161iritev FEAT_AFP, FEAT_RPRES in FEAT_XS, pa tudi fizi\u010dnih in virtualnih \u010dasovnikov EL2. Podpora za CPU Arm PXA2xx in emulacija ukazov iwMMXt je razgla\u0161ena za zastarelo.\n<li class=\"l\"> V emulatorju arhitekture RISC-V je bila uresni\u010dena emulacija plo\u0161\u010d Microblaze V, CPU Ascalon in CPU RV64 Xiangshan Nanhu. Dodana je podpora za raz\u0161iritve naborov ukazov &#8216;svukte&#8217;, &#8216;ssstateen&#8217;, &#8216;smrnmi&#8217;, &#8216;smdbltrp&#8217; \/ &#8217;ssdbltrp&#8217;, &#8216;supm&#8217;, &#8216;sspm&#8217;, ter oznake za prevajanje IOMMU in naprav riscv-iommu-sys.\n<li class=\"l\"> V emulatorju arhitekture HPPA je bila uvedena emulacija plo\u0161\u010d Diva GSP BMC. Do razli\u010dice 18 je bila posodobljena programska oprema SeaBIOS-hppa. Pove\u010dana je hitrost translacije. Izbolj\u0161ana je koda za ponastavitev virtualnega CPU. Na 64-bitnih sistemih je omogo\u010dena emulacija konfiguracij z velikostjo pomnilnika do 256 GB.\n<li class=\"l\"> V emulatorju arhitekture LoongArch je bila uvedena podpora za vro\u010de dodajanje CPU. Uveden je bil paravirtualizirani IPI (inter-processor interrupt). Omogo\u010deno je sledenje \u010dasu \u010dakanja na dodelitev virov s strani hipervizorja. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/sl\/vps\/abuzoustojchivye-vps\/\"   title=\"KVM\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"4440\">KVM<\/a>. Dodana je podpora za virtualno usmerjanje zunanjih prekinitev (extioi).\n<li class=\"l\"> V emulatorju arhitekture s390x je bila dodana podpora za 17. generacijo CPU-jev mainframe in uvedena podpora za virtio-mem. Za pove\u010danje zmogljivosti je bila dodana mo\u017enost interakcije s PCI-napravami obvladovanja IOMMU.    <\/ul>\n<p>Izvor: <a content=\"nofollow\" rel=\"nofollow\"
