Como emulador, o QEMU permite executar programas compilados para uma plataforma de hardware em um sistema com uma arquitetura totalmente diferente, por exemplo, executar um aplicativo para ARM em um PC compat\u00edvel com x86. No modo de virtualiza\u00e7\u00e3o, o desempenho da execu\u00e7\u00e3o de c\u00f3digo em um ambiente isolado \u00e9 pr\u00f3ximo ao de um sistema f\u00edsico, gra\u00e7as \u00e0 execu\u00e7\u00e3o direta de instru\u00e7\u00f5es na CPU e \u00e0 utiliza\u00e7\u00e3o do hipervisor Xen ou do m\u00f3dulo KVM no Linux, ou do m\u00f3dulo NVMM no NetBSD.    <\/p>\n<p>O projeto foi inicialmente criado por Fabrice Bellard com o objetivo de permitir a execu\u00e7\u00e3o de arquivos execut\u00e1veis Linux compilados para a plataforma x86 em arquiteturas diferentes de x86. Ao longo dos anos de desenvolvimento, foi adicionada suporte completo para 14 arquiteturas de hardware, e o n\u00famero de dispositivos de hardware emulados ultrapassou 400. Para a vers\u00e3o 10.0, mais de 2800 altera\u00e7\u00f5es foram feitas por 211 desenvolvedores.     <\/p>\n<p>Melhorias principais adicionadas ao QEMU 10.0:   <\/p>\n<ul>\n<li class=\"l\"> No driver virtio-scsi, que fornece um controlador SCSI virtual (SCSI Host Bus Adapter) para <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/vps\/\"   title=\"m\u00e1quinas virtuais\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2201\">m\u00e1quinas virtuais<\/a>, foi adicionada a suporte para um sistema de filas multiqueue, permitindo a divis\u00e3o de filas para diferentes dispositivos de bloco, garantindo acesso multithread em sistemas multin\u00facleos (diferentes filas de um \u00fanico dispositivo podem ser processadas por diferentes threads de entrada\/sa\u00edda). Em compara\u00e7\u00e3o com o driver de dispositivo de bloco virtual (virtio-blk), o controlador SCSI virtual tem um desempenho ligeiramente inferior, mas permite o uso de mais de 28 discos.\n<li class=\"l\"> No VFIO (Virtual Function I\/O), melhorou-se o suporte ao encaminhamento de IGD (Integrated Graphics Device) para GPUs integrados utilizados nas 11\u00aa (Rocket Lake) e 12\u00aa (Alder Lake) gera\u00e7\u00f5es de processadores Intel. Adicionou-se suporte para GPUs mais antigas da ATI (x550). Implementou-se suporte b\u00e1sico para PCI PM (Power Management).\n<li class=\"l\"> A documenta\u00e7\u00e3o do protocolo QMP (QEMU Machine Protocol) foi significativamente reescrita e expandida, permitindo que aplicativos gerenciem o QEMU.\n<li class=\"l\"> Foi adicionado um novo modo de migra\u00e7\u00e3o ao vivo &#171;cpr-transfer&#187; (Checkpoint and Restart), permitindo mover o sistema convidado para uma nova inst\u00e2ncia do QEMU, executada no mesmo host. O modo minimiza o tempo de pausa ao refletir a mem\u00f3ria do sistema convidado no espa\u00e7o de endere\u00e7o virtual do novo QEMU sem copiar o conte\u00fado.\n<li class=\"l\"> Foram adicionados dispositivos gr\u00e1ficos &#8216;apple-gfx-pci&#8217; e &#8216;apple-gfx-mmio&#8217;, que utilizam o framework ParavirtualizedGraphics, fornecido no macOS para acelera\u00e7\u00e3o gr\u00e1fica de hardware em sistemas convidados. O primeiro driver \u00e9 destinado a uso em dispositivos x86-64, enquanto o segundo &#8212; ARM64.\n<li class=\"l\"> No emulador da arquitetura x86, foi implementado suporte para os modelos de processadores Intel Xeon Clearwater Forest e Sierra Forest v2. A emula\u00e7\u00e3o de instru\u00e7\u00f5es para manipula\u00e7\u00e3o de dados de string foi acelerada.\n<li class=\"l\"> No emulador da arquitetura ARM, foi implementado suporte para as placas NPCM8445 Evaluation e i.MX 8M Plus EVK. Foram adicionadas emula\u00e7\u00f5es das extens\u00f5es FEAT_AFP, FEAT_RPRES e FEAT_XS, assim como temporizadores f\u00edsicos e virtuais EL2. O suporte para CPU Arm PXA2xx e a emula\u00e7\u00e3o de instru\u00e7\u00f5es iwMMXt foram declarados obsoletos.\n<li class=\"l\"> No emulador da arquitetura RISC-V, foi implementada a emula\u00e7\u00e3o de placas Microblaze V, CPU Ascalon e CPU RV64 Xiangshan Nanhu. Foi adicionada a suporte para extens\u00f5es do conjunto de instru\u00e7\u00f5es &#8216;svukte&#8217;, &#8216;ssstateen&#8217;, &#8216;smrnmi&#8217;, &#8216;smdbltrp&#8217;\/'ssdbltrp&#8217;, &#8216;supm&#8217;, &#8216;sspm&#8217;, assim como tags de tradu\u00e7\u00e3o IOMMU e dispositivos riscv-iommu-sys.\n<li class=\"l\"> No emulador da arquitetura HPPA, foi assegurada a emula\u00e7\u00e3o das placas Diva GSP BMC. A firmware SeaBIOS-hppa foi atualizada at\u00e9 a vers\u00e3o 18. A velocidade de tradu\u00e7\u00e3o foi aumentada. O c\u00f3digo para redefinir o CPU virtual foi aprimorado. Em sistemas de 64 bits, foi assegurada a emula\u00e7\u00e3o de configura\u00e7\u00f5es com tamanho de mem\u00f3ria de at\u00e9 256 GB.\n<li class=\"l\"> No emulador da arquitetura LoongArch, foi introduzido suporte para conex\u00e3o quente de CPU. Foi implementado um IPI (interrup\u00e7\u00e3o entre processadores) paravirtualizado. O rastreamento do tempo de espera para fornecimento de recursos pelo hipervisor foi assegurado. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/vps\/abuzoustojchivye-vps\/\"   title=\"KVM\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"4440\">KVM<\/a>Foi adicionada a suporte \u00e0 roteamento virtual de interrup\u00e7\u00f5es externas (extioi).\n<li class=\"l\"> No emulador da arquitetura s390x, foi adicionado suporte para a 17\u00aa gera\u00e7\u00e3o de CPUs de mainframes e implementado suporte ao virtio-mem. Para melhorar o desempenho, foi adicionada a capacidade de intera\u00e7\u00e3o com dispositivos PCI contornando o IOMMU.    <\/ul>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
