Come emulatore, QEMU consente di eseguire un programma compilato per una piattaforma hardware su un sistema con un'architettura completamente diversa, ad esempio eseguire un'applicazione per ARM su un PC compatibile x86. In modalit\u00e0 di virtualizzazione, QEMU offre prestazioni di esecuzione del codice in un ambiente isolato quasi paragonabili a quelle di un sistema hardware grazie all'esecuzione diretta delle istruzioni sulla CPU e all'uso dell'ipersemplificatore Xen o del modulo KVM.       <\/p>\n<p>Originariamente, il progetto \u00e8 stato creato da Fabrice Bellard con l'obiettivo di fornire la possibilit\u00e0 di eseguire eseguibili Linux compilati per la piattaforma x86 su architetture diverse da x86. Nel corso degli anni di sviluppo, \u00e8 stato aggiunto il supporto per l'emulazione completa di 14 architetture hardware, superando i 400 dispositivi hardware emulati. Per la versione 7.1 sono state apportate oltre 2800 modifiche da 238 sviluppatori.     <\/p>\n<p>Miglioramenti chiave aggiunti in QEMU 7.1:   <\/p>\n<ul>\n<li class=\"l\"> Sulla piattaforma Linux \u00e8 stata implementata l'opzione zero-copy-send, che consente il trasferimento di pagine di memoria durante la live-migration senza buffering intermedio.\n<li class=\"l\"> In QMP (QEMU Machine Protocol) the ability to use the block-export-add command for exporting NBD images with page information in the 'dirty' state has been added. New commands 'query-stats' and 'query-stats-schema' have also been added for querying statistics from various QEMU subsystems.\n<li class=\"l\"> The agent for guest systems has improved support for the Solaris platform, and new commands 'guest-get-diskstats' and 'guest-get-cpustats' have been added to display the status of disks and CPU. The 'guest-get-disks' command now includes output from NVMe SMART, while the 'guest-get-fsinfo' command outputs data about the NVMe bus type.\n<li class=\"l\"> \u00c8 stato aggiunto un nuovo emulatore LoongArch con supporto per la variante a 64 bit dell'architettura del set di istruzioni LoongArch (LA64). L'emulatore supporta i processori Loongson 3 5000 e i bridge nordici Loongson 7A1000.\n<li class=\"l\"> New types of emulated machines have been implemented in the ARM emulator: Aspeed AST1030 SoC, Qualcomm and AST2600 \/ AST1030 (fby35). Emulation support for Cortex-A76 and Neoverse-N1 CPUs has been added, along with processor extensions SME (Scalable Matrix Extensions), RAS (Reliability, Availability, Serviceability) and commands to prevent cache leaks during speculative instruction execution on CPU. For 'virt' machines, emulation of the GICv4 interrupt controller has been introduced.\n<li class=\"l\"> Nel simulatore architettonico x86 \u00e8 stata <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/vps\/abuzoustojchivye-vps\/\"   title=\"KVM\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"4410\">KVM<\/a>  aggiunta la supporto per la virtualizzazione del meccanismo di tracciamento LBR (Last Branch Record).\n<li class=\"l\"> Nel simulatore architettonico HPPA \u00e8 stato proposto un nuovo firmware basato su SeaBIOS v6, che supporta l'uso della tastiera PS\/2 nel menu di avvio. \u00c8 stata migliorata l'emulazione della porta seriale. Sono stati aggiunti font della console STI.\n<li class=\"l\"> Nel simulatore architettonico MIPS per schede Nios2 (-machine 10m50-ghrd) \u00e8 stata implementata l'emulazione del controller di interruzione vettoriale (Vectored Interrupt Controller) e del set di registri shadow. \u00c8 stata migliorata la gestione delle eccezioni.\n<li class=\"l\"> In the OpenRISC architecture emulator for the 'or1k-sim' machine, the use of up to 4 UART devices 16550A has been enabled.\n<li class=\"l\"> In the RISC-V architecture emulator, support for new instruction set extensions (ISA) defined in specification 1.12.0 has been added, along with support for the Sdtrig extension and improved support for vector instructions. Debugging capabilities have been expanded. The 'virt' emulated machine now includes support for TPM (Trusted Platform Module), while the 'OpenTitan' machine supports Ibex SPI.\n<li class=\"l\"> L'emulatore dell'architettura 390x supporta le estensioni VEF 2 (Vector-Enhancements Facility 2). Nel BIOS s390-ccw \u00e8 stata implementata la possibilit\u00e0 di avvio da dischi con dimensioni del settore diverse da 512 byte.\n<li class=\"l\"> Nell'emulatore dell'architettura Xtensa \u00e8 stato aggiunto il supporto per i core lx106 e i codici oggetto per il testing della cache.  <\/ul>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
