Kot emulator QEMU omogo\u010da zagon programa, sestavljenega za eno strojno platformo, na sistemu z povsem druga\u010dno arhitekturo, na primer, izvajanje aplikacije za ARM na x86-zdru\u017eljivem osebnem ra\u010dunalniku. V na\u010dinu virtualizacije QEMU zmogljivost izvajanja kode v izoliranem okolju je blizu strojni sistemski zmogljivosti zaradi neposrednega izvajanja ukazov na CPU in anga\u017eiranja hipervizorja Xen ali modula KVM v Linuxu, ali modula NVMM v NetBSD.    <\/p>\n<p>Projekt je prvotno ustvaril Fabrice Bellard z namenom omogo\u010diti zagon izvr\u0161nih datotek Linux, zbranih za platformo x86, na arhitekturah, ki se razlikujejo od x86. Skozi leta razvoja je bila dodana podpora za popolno emulacijo za 14 strojnih arhitektur, \u0161tevilo emuliranih strojnih naprav pa je preseglo 400. Pri pripravi razli\u010dice 11.0.0 je bilo izvedenih ve\u010d kot 2500 sprememb od 237 razvijalcev.     <\/p>\n<p>Klju\u010dne izbolj\u0161ave, dodane v QEMU 11.0:   <\/p>\n<ul>\n<li class=\"l\"> Podpora za 32-bitne hlejenjske sisteme je bila odstranjena, kar je bilo razgla\u0161eno za zastarelo aprila lani v QEMU 10.0. V decembrskem izidu 10.2 je prenehala podpora za platforme mips32 in ppc32 v generatorju kode TCG (Tiny Code Generator), v izidu QEMU 11.0 pa so odstranjene preostale platforme i386, arm, ppc in riscv32, prav tako je bila izvedena \u010di\u0161\u010denja kode in zbiralne sistema od komponent za delo na 32-bitnih hlejenjskih sistemih.\n<li class=\"l\"> Implementiran je akcelerator virtualizacije \"nitro\" (\"-accel nitor\") i nova vrsta emuliranih sistema \"nitro\", koja omogu\u0107ava pokretanje izolovanih enklava baziranih na tehnologiji poverljivih ra\u010dunarstva AWS Nitro Enclave u QEMU, na primer, za lokalno testiranje Nitro Enclave okru\u017eenja u QEMU. U AWS EC2, tehnologija Nitro Enclave omogu\u0107ava pokretanje u virtuelnoj ma\u0161ini ugnije\u017edenih izolovanih enklava za rad sa poverljivim podacima, dodeljuju\u0107i im deo svojih resursa.\n<li class=\"l\"> Izbolj\u0161ana je podpora za pospe\u0161evalnike virtualizacije MSHV (Microsoft Hypervisor) in WHPX (Microsoft Windows Hypervisor Platform Extensions).\n<li class=\"l\"> Kada se koristi hipervizor KVM (\"-accel kvm\"), podr\u017eava se virtualizacija Intel CET (Control-flow Enforcement Technology) za primenu u <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/sl\/vps\/abuzoustojchivye-vps\/\"   title=\"virtualnim ma\u0161inama\" data-wpil-keyword-link=\"linked\">virtualnim ma\u0161inama<\/a> za\u0161titi od eksploata koji koriste metode povratno-orijentisanog programiranja (ROP \u2014 Return-Oriented Programming). Tako\u0111e je dodata podr\u0161ka za ponovno pokretanje poverljivih <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/sl\/vps\/\"   title=\"virtualnih naprav\" data-wpil-keyword-link=\"linked\">virtualnih naprav<\/a>, koriste\u0107i za \u0161ifrovanje memorije pro\u0161irenja AMD SEV-SNP (Secure Encrypted Virtualization \u2014 Secure Nested Paging) i Intel TDX (Trust Domain Extensions).\n<li class=\"l\"> V napravo VirtIO-GPU, ki omogo\u010da delovanje virtualnega GPU, je dodana mo\u017enost nastavitve razli\u010dnih lo\u010dljivosti zaslona za razli\u010dne izhodne naprave.\n<li class=\"l\"> U VirtIO-GPU dodata je podr\u0161ka za DRM (Direct Rendering Manager native context) kontekste, koji pobolj\u0161avaju performanse rada sa virtuelnim GPU iz gostuju\u0107eg sistema preko direktnog prosle\u0111ivanja komandi stvarnom host GPU-u. Podr\u0161ka za DRM kontekste aktivira se kada se koristi novo ure\u0111aj virtio-gpu-gl sa opcijom \"drm_native_context=on\". Za razliku od Virgl i Venus konteksta, koji rade na nivou API OpenGL i Vulkan, DRM kontekst je implementiran na nivou UAPI jezgra Linuxa.\n<li class=\"l\"> Dodana je bila mo\u017enost uporabe jezika C++ za razvoj vti\u010dnikov za generator kode TCG (Tiny Code Generator).\n<li class=\"l\"> Blokiranemu vmesniku NFS je bila dodana podpora za gradnjo z knji\u017enico libnfs 6.\n<li class=\"l\"> U blok drajveru curl dodata je opcija \"force-range\" za prisilno kori\u0161\u0107enje HTTP zaglavlja \"Range\" pri preuzimanju slika bez prethodnog proveravanja njegove podr\u0161ke zasebnim zahtevom sa zaglavljem HEAD.\n<li class=\"l\"> V blokiranem vmesniku FUSE je bila onemogo\u010dena obdelava operacij izvoza v sinhronem na\u010dinu, ki je ovirala zagon virtualnega stroja do konca obdelave drugih FUSE zahtevkov. Dodana je mo\u017enost uporabe ve\u010dih nitk vhod\/izhod (iothread) pri izvajanju izvoza v FUSE.\n<li class=\"l\"> U emulatoru arhitekture x86 dodata je podr\u0161ka za CPU Intel Diamond Rapids (\"Xeon 7\").\n<li class=\"l\"> Emulator arhitekture ARM je dodal procesorske raz\u0161iritve FEAT_ASID2 in FEAT_E2H0. V generatorju kode TCG je bila implementirana emulacija raz\u0161iritev SME (Scalable Matrix Extension).\n<li class=\"l\"> Emulator arhitekture HPPA je dodal podporo za emulacijo 64-bitnih procesorjev s 40- in 44-bitnim naslovnim prostorom. Z uporabo SeaBIOS-hppa 24 je bila omogo\u010dena inicializacija PCI-nadzornika Astro, ki omogo\u010da uporabo PCI-grafi\u010dnih kartic na 64-bitnih sistemih.\n<li class=\"l\"> V emulatorju arhitekture LoongArch je postala mo\u017ena migracija PMU (Performance Monitoring Unit) pri uporabi hipervizorja KVM. V generatorju kode TCG je bila implementirana emulacija raz\u0161iritev LA v1.1, sc.q in llacq\/screl, pa tudi ukazov FRECIP in DRECIP za izra\u010dunavanje obratnih vrednosti.\n<li class=\"l\"> Emulator arhitekture PowerPC je pridobil podporo za zajemanje.\n<li class=\"l\"> V emulatorju arhitekture RISC-V je bila implementirana podpora za CPU MIPS P8700 in raz\u0161iritve zbirke ukazov Zilsd, Zclsd, ZALASR in Smpmpmt.\n<li class=\"l\">  U emulatoru arhitekture s390 pojavila se podr\u0161ka za pokretanje sa virtio-blk-pci ure\u0111aja i implementirana je emulacija instrukcije \"DIVIDE TO INTEGER\".\n<li class=\"l\"> Usvojena su ispravka koja 50-80 puta smanjuje latencije pri radu fdmon (file descriptor monitoring) u re\u017eimu \"aio=io_uring\" i kada je sistem u stanju mirovanja (idle).<br \/>\n<br \/>Izvor: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=65269\">opennet.ru<\/a>
